Main enabling factor of this promising paradigm is the integration of several technologies and communications solutions. Identification and tracking technologies, wired and wireless sensor and actuator networks, enhanced communication protocols (shared with the Next Generation Internet), and distributed intelligence for smart objects are just the most relevant. As one can easily imagine, any serious contribution to the advance of the Internet of Things must necessarily be the result of synergetic activities conducted in different fields of knowledge, such as telecommunications, informatics, electronics and social science. In such a complex scenario, this survey is directed to those who want to approach this complex discipline and contribute to its development. Different visions of this Internet of Things paradigm are reported and enabling technologies reviewed. What emerges is that still major issues shall be faced by the research community. The most relevant among them are addressed in details.链接：http://www.sciencedirect.com/science/article/pii/S138912861000156
2. 标题：Synthesis and surface engineering of iron oxide nanoparticles for biomedical applications • Review article 出处：Biomaterials, Volume 26, Issue 18, June 2005, Pages 3995-4021作者：Gupta, A.K.; Gupta, M. 摘要： Superparamagnetic iron oxide nanoparticles (SPION) with appropriate surface chemistry have been widely used experimentally for numerous in vivo applications such as magnetic resonance imaging contrast enhancement, tissue repair, immunoassay, detoxification of biological fluids, hyperthermia, drug delivery and in cell separation, etc. All these biomedical and bioengineering applications require that these nanoparticles have high magnetization values and size smaller than 100 nm with overall narrow particle size distribution, so that the particles have uniform physical and chemical properties. In addition, these applications need special surface coating of the magnetic particles, which has to be not only non-toxic and biocompatible but also allow a targetable delivery with particle localization in a specific area. To this end, most work in this field has been done in improving the biocompatibility of the materials, but only a few scientific investigations and developments have been carried out in improving the quality of magnetic particles, their size distribution, their shape and surface in addition to characterizing them to get a protocol for the quality control of these particles. Nature of surface coatings and their subsequent geometric arrangement on the nanoparticles determine not only the overall size of the colloid but also play a significant role in biokinetics and biodistribution of nanoparticles in the body. The types of specific coating, or derivatization, for these nanoparticles depend on the end application and should be chosen by keeping a particular application in mind, whether it be aimed at inflammation response or anti-

cancer agents. Magnetic nanoparticles can bind to drugs, proteins, enzymes, antibodies, or nucleotides and can be directed to an organ, tissue, or tumour using an external magnetic field or can be heated in alternating magnetic fields for use in hyperthermia. This review discusses the synthetic chemistry, fluid stabilization and surface modification of superparamagnetic iron oxide nanoparticles, as well as their use for above biomedical applications.链接：http://www.sciencedirect.com/science/article/pii/S0142961204009317
3. 标题：Data-intensive applications, challenges, techniques and technologies: A survey on Big Data • Article 出处：Information Sciences, Volume 275, August 2014, Pages 314-347作者：Philip Chen, C.L.; Zhang, C.Y. 摘要： It is already true that Big Data has drawn huge attention from researchers in information sciences, policy and decision makers in governments and enterprises. As the speed of information growth exceeds Moore’s Law at the beginning of this new century, excessive data is making great troubles to human beings. However, there are so much potential and highly useful values hidden in the huge volume of data. A new scientific paradigm is born as data-intensive scientific discovery (DISD), also known as Big Data problems. A large number of fields and sectors, ranging from economic and business activities to public administration, from national security to scientific researches in many areas, involve with Big Data problems. On the one hand, Big Data is extremely valuable to produce productivity in businesses and evolutionary breakthroughs in scientific disciplines, which give us a lot of opportunities to make great progresses in many fields. There is no doubt that the future competitions in business productivity and technologies will surely converge into the Big Data explorations. On the other hand, Big Data also arises with many challenges, such as difficulties in data capture, data storage, data analysis and data visualization. This paper is aimed to demonstrate a close-up view about Big Data, including Big Data applications, Big Data opportunities and challenges, as well as the state-of-the-art techniques and technologies we currently adopt to deal with the Big Data problems. We also discuss several underlying methodologies to handle the data deluge, for example, granular computing, cloud computing, bio-inspired computing, and quantum computing.链接：http://www.sciencedirect.com/science/article/pii/S0020025514000346
4. 标 题 ： A review on polymer nanofibers by electrospinning and their applications in nanocomposites • Article 出处：Composites Science and Technology, Volume 63, Issue 15, November 2003, Pages 2223-2253作者：Huang, Z.-M.; Zhang, Y.-Z.; Kotaki, M.; Ramakrishna, S. 摘要：Electrospinning has been recognized as an efficient technique for the fabrication of polymer nanofibers. Various polymers have been successfully electrospun into ultrafine fibers in recent years mostly in solvent solution and some in melt form. Potential applications based on such fibers specifically their use as reinforcement in nanocomposite development have been realized. In this paper, a comprehensive review is presented on the researches and developments related to electrospun polymer nanofibers including processing, structure and property characterization, applications, and modeling and simulations. Information of those polymers together with their processing conditions for electrospinning of ultrafine fibers has been summarized in the paper. Other issues regarding the technology limitations, research challenges, and future trends are also discussed.

5. 标题：Project management: cost, time and quality, two best guesses and a phenomenon, its time to accept other success criteria • Article 出处： International Journal of Project Management, Volume 17, Issue 6, December 1999, Pages 337-342作者：Atkinson, Roger 摘要：This paper provides some thoughts about success criteria for IS–IT project management. Cost, time and quality (The Iron Triangle), over the last 50 years have become inextricably linked with measuring the success of project management. This is perhaps not surprising, since over the same period those criteria are usually included in the description of project management. Time and costs are at best, only guesses, calculated at a time when least is known about the project. Quality is a phenomenon, it is an emergent property of peoples different attitudes and beliefs, which often change over the development life-cycle of a project. Why has project management been so reluctant to adopt other criteria in addition to the Iron Triangle, such as stakeholder benefits against which projects can be assessed? This paper proposes a new framework to consider success criteria, The Square Route.链接：http://www.sciencedirect.com/science/article/pii/S0263786398000696
6. 标题：A review of shape memory alloy research, applications and opportunities • Review article 出处：Materials & Design, Volume 56, April 2014, Pages 1078-1113作者：Mohd Jani, J.; Leary, M.; Subic, A.; Gibson, M.A. 摘要：Shape memory alloys (SMAs) belong to a class of shape memory materials (SMMs), which have the ability to ‘memorise’ or retain their previous form when subjected to certain stimulus such as thermomechanical or magnetic variations. SMAs have drawn significant attention and interest in recent years in a broad range of commercial applications, due to their unique and superior properties; this commercial development has been supported by fundamental and applied research studies. This work describes the attributes of SMAs that make them ideally suited to actuators in various applications, and addresses their associated limitations to clarify the design challenges faced by SMA developers. This work provides a timely review of recent SMA research and commercial applications, with over 100 state-of-the-art patents; which are categorised against relevant commercial domains and rated according to design objectives of relevance to these domains (particularly automotive, aerospace, robotic and biomedical). Although this work presents an extensive review of SMAs, other categories of SMMs are also discussed; including a historical overview, summary of recent advances and new application opportunities.链接：http://www.sciencedirect.com/science/article/pii/S0261306913011345

SPR sensor technology has been commercialized and SPR biosensors have become a central tool for characterizing and quantifying biomolecular interactions. This paper attempts to review the major developments in SPR technology. Main application areas are outlined and examples of applications of SPR sensor technology are presented. Future prospects of SPR sensor technology are discussed.链接：http://www.sciencedirect.com/science/article/pii/S0925400598003219
9. 标题：Parametric characterization of the geometry of honed cutting edges • Article 出处：Precision Engineering, Volume 37, Issue 3, July 2013, Pages 746-752作者：Yussefian, N.Z.; Koshy, P. 摘要：Development of methodologies for the geometric characterization of cutting edges is of significant current interest, in light of the profound influence that the edge geometry wields on virtually every machining response, and the evolving capability for generating tailored edges. This paper proposes the parametric modeling of the tool edge geometry through the application of free-knot B-splines that comprise three piecewise segments corresponding to the cutting edge profile and the two tool faces. The transition points that demarcate the cutting edge from the tool faces are objectively and robustly identified by the adaptive placement of the knots that minimizes the residual error from fitting the B-spline to the tool profile data. On identification of the cutting edge, the edge profile is modeled by parametric quadratics to yield four geometrically relevant, contour-based parameters that characterize both symmetric and asymmetric honed edges.链接：http://www.sciencedirect.com/science/article/pii/S0141635913000482、10. 标题：A survey on security issues in service delivery models of cloud computing • Review article 出处：Journal of Network and Computer Applications, Volume 34, Issue 1, January 2011, Pages 1-11作者：Subashini, S.; Kavitha, V. 摘要：Cloud computing is a way to increase the capacity or add capabilities dynamically without investing in new infrastructure, training new personnel, or licensing new software. It extends Information Technology’s (IT) existing capabilities. In the last few years, cloud computing has grown from being a promising business concept to one of the fast growing segments of the IT industry. But as more and more information on individuals and companies are placed in the cloud, concerns are beginning to grow about just how safe an environment it is. Despite of all the hype surrounding the cloud, enterprise customers are still reluctant to deploy their business in the cloud. Security is one of the major issues which reduces the growth of cloud computing and complications with data privacy
4
and data protection continue to plague the market. The advent of an advanced model should not negotiate with the required functionalities and capabilities present in the current model. A new model targeting at improving features of an existing model must not risk or threaten other important features of the current model. The architecture of cloud poses such a threat to the security of the existing technologies when deployed in a cloud environment. Cloud service users need to be vigilant in understanding the risks of data breaches in this new environment. In this paper, a survey of the different security risks that pose a threat to the cloud is presented. This paper is a survey more specific to the different security issues that has emanated due to the nature of the service delivery models of a cloud computing system.链接：http://www.sciencedirect.com/science/article/pii/S1084804510001281
11. 标题：Review on thermal energy storage with phase change: materials, heat transfer analysis and applications • Review article 出处：Applied Thermal Engineering, Volume 23, Issue 3, February 2003, Pages 251-283作者：Zalba, B.; Marn, J.M.S.T.; Cabeza, L.F.; Mehling, H. 摘要：Thermal energy storage in general, and phase change materials (PCMs) in particular, have been a main topic in research for the last 20 years, but although the information is quantitatively enormous, it is also spread widely in the literature, and difficult to find. In this work, a review has been carried out of the history of thermal energy storage with solid–liquid phase change. Three aspects have been the focus of this review: materials, heat transfer and applications. The paper contains listed over 150 materials used in research as PCMs, and about 45 commercially available PCMs. The paper lists over 230 references.链接：http://www.sciencedirect.com/science/article/pii/S1359431102001928
12. 标题：A review on buildings energy consumption information • Article 出处：Energy and Buildings, Volume 40, Issue 3, January 2008, Pages 394-398作者：Perez-Lombard, L.; Ortiz, J.; Pout, C. 摘要：The rapidly growing world energy use has already raised concerns over supply difficulties, exhaustion of energy resources and heavy environmental impacts (ozone layer depletion, global warming, climate change, etc.). The global contribution from buildings towards energy consumption, both residential and commercial, has steadily increased reaching figures between 20% and 40% in developed countries, and has exceeded the other major sectors: industrial and transportation. Growth in population, increasing demand for building services and comfort levels, together with the rise in time spent inside buildings, assure the upward trend in energy demand will continue in the future. For this reason, energy efficiency in buildings is today a prime objective for energy policy at regional, national and international levels. Among building services, the growth in HVAC systems energy use is particularly significant (50% of building consumption and 20% of total consumption in the USA). This paper analyses available information concerning energy consumption in buildings, and particularly related to HVAC systems. Many questions arise: Is the necessary information available? Which are the main building types? What end uses should be considered in the breakdown? Comparisons between different countries are presented specially for commercial buildings. The case of offices is analysed in deeper detail.链接：http://www.sciencedirect.com/science/article/pii/S0378778807001016

13. 标题：Trends in big data analytics • Article 出处：Journal of Parallel and Distributed Computing, Volume 74, Issue 7, July 2014, Pages 2561-2573作者：Kambatla, K.; Kollias, G.; Kumar, V.; Grama, A. 摘要：One of the major applications of future generation parallel and distributed systems is in big-data analytics. Data repositories for such applications currently exceed exabytes and are rapidly increasing in size. Beyond their sheer magnitude, these datasets and associated applications’ considerations pose significant challenges for method and software development. Datasets are often distributed and their size and privacy considerations warrant distributed techniques. Data often resides on platforms with widely varying computational and network capabilities. Considerations of fault-tolerance, security, and access control are critical in many applications (Dean and Ghemawat, 2004; Apache hadoop). Analysis tasks often have hard deadlines, and data quality is a major concern in yet other applications. For most emerging applications, data-driven models and methods, capable of operating at scale, are as-yet unknown. Even when known methods can be scaled, validation of results is a major issue. Characteristics of hardware platforms and the software stack fundamentally impact data analytics. In this article, we provide an overview of the state-of-the-art and focus on emerging trends to highlight the hardware, software, and application landscape of big-data analytics.链接：http://www.sciencedirect.com/science/article/pii/S0743731514000057
14. 标题：Scaffolds in tissue engineering bone and cartilage • Article 出处：Biomaterials, Volume 21, Issue 24, December 2000, Pages 2529-2543作者：Hutmacher, D.W. 摘要： Musculoskeletal tissue, bone and cartilage are under extensive investigation in tissue engineering research. A number of biodegradable and bioresorbable materials, as well as scaffold designs, have been experimentally and/or clinically studied. Ideally, a scaffold should have the following characteristics: (i) three-dimensional and highly porous with an interconnected pore network for cell growth and flow transport of nutrients and metabolic waste; (ii) biocompatible and bioresorbable with a controllable degradation and resorption rate to match cell/tissue growth in vitro and/or in vivo; (iii) suitable surface chemistry for cell attachment, proliferation, and differentation and (iv) mechanical properties to match those of the tissues at the site of implantation. This paper reviews research on the tissue engineering of bone and cartilage from the polymeric scaffold point of view.链接：http://www.sciencedirect.com/science/article/pii/S0142961200001216

16. 标题：Wireless sensor network survey • Article 出处：Computer Networks, Volume 52, Issue 12, August 2008, Pages 2292-2330作者：Yick, J.; Mukherjee, B.; Ghosal, D. 摘要：A wireless sensor network (WSN) has important applications such as remote environmental monitoring and target tracking. This has been enabled by the availability, particularly in recent years, of sensors that are smaller, cheaper, and intelligent. These sensors are equipped with wireless interfaces with which they can communicate with one another to form a network. The design of a WSN depends significantly on the application, and it must consider factors such as the environment, the application’s design objectives, cost, hardware, and system constraints. The goal of our survey is to present a comprehensive review of the recent literature since the publication of [I.F. Akyildiz, W. Su, Y. Sankarasubramaniam, E. Cayirci, A survey on sensor networks, IEEE Communications Magazine, 2002]. Following a top-down approach, we give an overview of several new applications and then review the literature on various aspects of WSNs. We classify the problems into three different categories: (1) internal platform and underlying operating system, (2) communication protocol stack, and (3) network services, provisioning, and deployment. We review the major development in these three categories and outline new challenges.链接：http://www.sciencedirect.com/science/article/pii/S0263786301000679
17. 标题：A review of solar collectors and thermal energy storage in solar thermal applications • Article 出处：Applied Energy, Volume 104, April 2013, Pages 538-553作者：Tian, Y.; Zhao, C.Y. 摘要：Thermal applications are drawing increasing attention in the solar energy research field, due to their high performance in energy storage density and energy conversion efficiency. In these applications, solar collectors and thermal energy storage systems are the two core components. This paper focuses on the latest developments and advances in solar thermal applications, providing a review of solar collectors and thermal energy storage systems. Various types of solar collectors are reviewed and discussed, including both non-concentrating collectors (low temperature applications) and concentrating collectors (high temperature applications). These are studied in terms of optical optimisation, heat loss reduction, heat recuperation enhancement and different sun-tracking mechanisms. Various types of thermal energy storage systems are also reviewed and discussed, including sensible heat storage, latent heat storage, chemical storage and cascaded storage. They are studied in terms of design criteria, material selection and different heat transfer enhancement technologies. Last but not least, existing and future solar power stations are overviewed.链接：http://www.sciencedirect.com/science/article/pii/S0306261912008549
18. 标题：Leadership competency profiles of successful project managers • Article 出处：International Journal of Project Management, Volume 28, Issue 5, July 2010, Pages 437-448作者：Müller, Ralf; Turner, Rodney 摘要：This study examines the leadership competency profiles of successful project managers in different types of projects. Four hundred responses to the Leadership Development Questionnaire (LDQ) were used to profile the intellectual, managerial and emotional competences (IQ, MQ and EQ, respectively) of project managers of successful projects. Differences by project type were accounted
7
for through categorization of projects by their application type (engineering & construction, information & telecommunication technology, organizational change), complexity, importance and contract type. Results indicate high expressions of one IQ sub-dimension (i.e. critical thinking) and three EQ sub-dimensions (i.e. influence, motivation and conscientiousness) in successful managers in all types of projects. Other sub-dimensions varied by project type. Comparison was made to existing profiles for goal oriented, involving and engaging leadership styles. Implications derived are the need for practitioners to be trained in the soft factors of leadership, particular for their types of projects. Theoretical implications include the need for more transactional styles in relatively simple projects and more transformational leadership styles in complex projects.链接：http://www.sciencedirect.com/science/article/pii/S0263786309000970

Materials and fabrication routes for three-dimensional (3D) scaffolds with interconnected high porosities suitable for bone tissue engineering are reviewed. Different polymer and ceramic compositions applied and their impact on biodegradability and bioactivity of the scaffolds are discussed, including in vitro and in vivo assessments. The mechanical properties of today's available porous scaffolds are analyzed in detail, revealing insufficient elastic stiffness and compressive strength compared to human bone. Further challenges in scaffold fabrication for tissue engineering such as biomolecules incorporation, surface functionalization and 3D scaffold characterization are discussed, giving possible solution strategies. Stem cell incorporation into scaffolds as a future trend is addressed shortly, highlighting the immense potential for creating next-generation synthetic/living composite biomaterials that feature high adaptiveness to the biological environment.链接：http://www.sciencedirect.com/science/article/pii/S0142961206001232
20. 标题：A block-based evolutionary algorithm for flow-shop scheduling problem • Article 出处：Applied Soft Computing, Volume 13, Issue 12, December 2013, Pages 4536-4547作者：Chang, P.C.; Chen, M.H.; Tiwari, M.K.; Iquebal, A.S. 摘 要 ： Combinatorial problems like flow shop scheduling, travel salesman problem etc. get complicated and are difficult to solve when the problem size increases. To overcome this problem, we present a block-based evolutionary algorithm (BBEA) which will conduct evolutionary operations on a set of blocks instead of genes. BBEA includes the block mining and block recombination approaches. A block mining algorithm is developed to decompose a chromosome into a set of blocks and rest of genes. The block is with a fixed length and can be treated as a building block in forming a new chromosome later on. To guide the block mining process, a gene linkage probability matrix is defined that shows the linkage strength among genes. Therefore the blocks can be further evolved during the evolutionary processes using this matrix. In the block recombination approach, the blocks along with the rest of genes are recombined to form a new chromosome. This new evolutionary approach of BBEA is tested on a set of discrete problems. Experimental results show that BBEA is very competitive when compared with traditional GA, EA or ACGA and HGIA
8
approaches and it can largely improve the performance of evolutionary algorithm and save a fair amount of computational times simultaneously.摘要：http://www.sciencedirect.com/science/article/pii/S1568494613002640

In doing so, the focus on environmental management and operations is moved from local optimization of environmental factors to consideration of the entire supply chain during the production, consumption, customer service and post-disposal disposition of products. This is a critical and timely topic that captures increasing concerns over sustainability, whether driven by current legislation, public interest, or competitive opportunity. As such, sustainable development is a rich area for academic research that is still in its infancy and has the potential to affect future government policy, current production operations, and identify new business models. This paper provides a background to better understand current trends in this multidisciplinary field that intersect with operations management, and the research opportunities and challenges it presents.链接：http://www.sciencedirect.com/science/article/pii/S0272696307000149
22. 标题：Exploring the value of project management: Linking Project Management Performance and Project Success • Article 出处：International Journal of Project Management作者：Mir, Farzana Asad; Pinnington, Ashly H. 摘要： The literature on Project Management (PM) shows that, in spite of advancement in PM processes, tools and systems, project success has not significantly improved. This problem raises questions about the value and effectiveness of PM and PM systems. This paper reports a research study which tests the relationship between PM performance and project success drawing from empirical data on PM professionals working in UAE project-based organisations.
Multi-dimensional frameworks are validated and used in this study to measure PM performance and project success. A total of 154 completed questionnaires were analysed. Bi-variate correlation and multiple regression tests found a positive influence of PM performance and its contributing variables on project success. Additionally, new variable relationships that have not previously been identified are explored between individual variables of PM performance and project success.链接：http://www.sciencedirect.com/science/article/pii/S0263786313000884

They are applied as space filling agents, as delivery vehicles for bioactive molecules, and as three-dimensional structures that organize cells and present stimuli to direct the formation of a desired tissue. Much of the success of scaffolds in these roles hinges on finding an appropriate material to address the critical physical, mass transport, and biological design variables inherent to each application. Hydrogels are
9
an appealing scaffold material because they are structurally similar to the extracellular matrix of many tissues, can often be processed under relatively mild conditions, and may be delivered in a minimally invasive manner. Consequently, hydrogels have been utilized as scaffold materials for drug and growth factor delivery, engineering tissue replacements, and a variety of other applications.链接：http://www.sciencedirect.com/science/article/pii/S0142961203003405
24. 标题：Building Information Modeling (BIM) for existing buildings - Literature review and future needs • Review article 出处：Automation in Construction, Volume 38, March 2014, Pages 109-127作者：Volk, R.; Stengel, J.; Schultmann, F. 摘要：While BIM processes are established for new buildings, the majority of existing buildings is not maintained, refurbished or deconstructed with BIM yet. Promising benefits of efficient resource management motivate research to overcome uncertainties of building condition and deficient documentation prevalent in existing buildings.
Due to rapid developments in BIM research, involved stakeholders demand a state-of-the-art overview of BIM implementation and research in existing buildings. This paper presents a review of over 180 recent publications on the topic. Results show scarce BIM implementation in existing buildings yet, due to challenges of (1) high modeling/conversion effort from captured building data into semantic BIM objects, (2) updating of information in BIM and (3) handling of uncertain data, objects and relations in BIM occurring in existing buildings.
Despite fast developments and spreading standards, challenging research opportunities arise from process automation and BIM adaption to existing buildings' requirements.链接：http://www.sciencedirect.com/science/article/pii/S092658051300191X

The literature on SCM that deals with strategies and technologies for effectively managing a supply chain is quite vast. In recent years, organizational performance measurement and metrics have received much attention from researchers and practitioners. The role of these measures and metrics in the success of an organization cannot be overstated because they affect strategic, tactical and operational planning and control. Performance measurement and metrics have an important role to play in setting objectives, evaluating performance, and determining future courses of actions. Performance measurement and metrics pertaining to SCM have not received adequate attention from researchers or practitioners. We developed a framework to promote a better understanding of the importance of SCM performance measurement and metrics. Using the current literature and the results of an empirical study of selected British companies, we developed the framework presented herein, in hopes that it would stimulate more interest in this important area.链接：http://www.sciencedirect.com/science/article/pii/S0925527303002561

2. 标题：Synthesis and surface engineering of iron oxide nanoparticles for biomedical applications • Review article 出处：Biomaterials, Volume 26, Issue 18, June 2005, Pages 3995-4021作者：Gupta, A.K.; Gupta, M. 摘要： Superparamagnetic iron oxide nanoparticles (SPION) with appropriate surface chemistry have been widely used experimentally for numerous in vivo applications such as magnetic resonance imaging contrast enhancement, tissue repair, immunoassay, detoxification of biological fluids, hyperthermia, drug delivery and in cell separation, etc. All these biomedical and bioengineering applications require that these nanoparticles have high magnetization values and size smaller than 100 nm with overall narrow particle size distribution, so that the particles have uniform physical and chemical properties. In addition, these applications need special surface coating of the magnetic particles, which has to be not only non-toxic and biocompatible but also allow a targetable delivery with particle localization in a specific area. To this end, most work in this field has been done in improving the biocompatibility of the materials, but only a few scientific investigations and developments have been carried out in improving the quality of magnetic particles, their size distribution, their shape and surface in addition to characterizing them to get a protocol for the quality control of these particles. Nature of surface coatings and their subsequent geometric arrangement on the nanoparticles determine not only the overall size of the colloid but also play a significant role in biokinetics and biodistribution of nanoparticles in the body. The types of specific coating, or derivatization, for these nanoparticles depend on the end application and should be chosen by keeping a particular application in mind, whether it be aimed at inflammation response or anti-cancer agents. Magnetic nanoparticles can bind to drugs, proteins, enzymes, antibodies, or nucleotides and can be directed to an organ, tissue, or tumour using an external magnetic field or can be heated in alternating magnetic fields for use in hyperthermia. This review discusses the synthetic chemistry, fluid stabilization and surface modification of superparamagnetic iron oxide nanoparticles, as well as their use for above biomedical applications.

3. 标题：The effect of heat treatment on the physical properties of sol-gel derived ZnO thin films • Article 出处：Applied Surface Science, Volume 255, Issue 11, March 2009, Pages 5812-5817作者：Raoufi, D.; Raoufi, T. 摘要：Zinc oxide (ZnO) thin films were deposited on microscope glass substrates by sol–gel spin coating method. Zinc acetate (ZnAc) dehydrate was used as the starting salt material source. A homogeneous and stable solution was prepared by dissolving ZnAc in the solution of monoethanolamine (MEA). ZnO thin films were obtained after preheating the spin coated thin films at 250 °C for 5 min after each coating. The films, after the deposition of the eighth layer, were annealed in air at temperatures of 300 °C, 400 °C and 500 °C for 1 h. The effect of thermal annealing in air on the physical properties of the sol–gel derived ZnO thin films are studied. The powder and its thin film were characterized by X-ray diffractometer (XRD) method. XRD analysis revealed that the annealed ZnO thin films consist of single phase ZnO with wurtzite structure (JCPDS 36-1451) and show the c-axis grain orientation. Increasing annealing temperature increased the c-axis orientation and the crystallite size of the film. The annealed films are highly transparent with average transmission exceeding 80% in the visible range (400–700 nm). The measured optical band gap values of the ZnO thin films were between 3.26 eV and 3.28 eV, which were in the range of band gap values of intrinsic ZnO (3.2–3.3 eV). SEM analysis of annealed thin films has shown a completely different surface morphology behavior.链接：http://www.sciencedirect.com/science/article/pii/S016943320900021X

出处：Surface Science Reports, Volume 48, Issue 5-8, January 2003, Pages 53-229作者：Diebold, U. 摘要：Titanium dioxide is the most investigated single-crystalline system in the surface science of metal oxides, and the literature on rutile (1 1 0), (1 0 0), (0 0 1), and anatase surfaces is reviewed. This paper starts with a summary of the wide variety of technical fields where TiO2 is of importance. The bulk structure and bulk defects (as far as relevant to the surface properties) are briefly reviewed. Rules to predict stable oxide surfaces are exemplified on rutile (1 1 0). The surface structure of rutile (1 1 0) is discussed in some detail. Theoretically predicted and experimentally determined relaxations of surface geometries are compared, and defects (step edge orientations, point and line defects, impurities, surface manifestations of crystallographic shear planes—CSPs) are discussed, as well as the image contrast in scanning tunneling microscopy (STM). The controversy about the correct model for the (1×2) reconstruction appears to be settled. Different surface preparation methods, such as reoxidation of reduced crystals, can cause a drastic effect on surface geometries and morphology, and recommendations for preparing different TiO2(1 1 0) surfaces are given. The structure of the TiO2(1 0 0)-(1×1) surface is discussed and the proposed models for the (1×3) reconstruction are critically reviewed. Very recent results on anatase (1 0 0) and (1 0 1) surfaces are included.
The electronic structure of stoichiometric TiO2 surfaces is now well understood. Surface defects can be detected with a variety of surface spectroscopies. The vibrational structure is dominated by strong Fuchs–Kliewer phonons, and high-resolution electron energy loss spectra often need to be deconvoluted in order to render useful information about adsorbed molecules.The growth of metals (Li, Na, K, Cs, Ca, Al, Ti, V, Nb, Cr, Mo, Mn, Fe, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au) as well as some metal oxides on TiO2 is reviewed. The tendency to ‘wet’ the overlayer, the growth morphology, the epitaxial relationship, and the strength of the interfacial oxidation/reduction reaction all follow clear trends across the periodic table, with the reactivity of the overlayer metal towards oxygen being the most decisive factor. Alkali atoms form ordered superstructures at low coverages. Recent progress in understanding the surface structure of metals in the ‘strong-metal support interaction’ (SMSI) state is summarized.Literature is reviewed on the adsorption and reaction of a wide variety of inorganic molecules (H2, O2, H2O, CO, CO2, N2, NH3, NOx, sulfur- and halogen-containing molecules, rare gases) as well as organic molecules (carboxylic acids, alcohols, aldehydes and ketones, alkynes, pyridine and its derivates, silanes, methyl halides). The application of TiO2-based systems in photo-active devices is discussed, and the results on UHV-based photocatalytic studies are summarized.
The review ends with a brief conclusion and outlook of TiO2-based surface science for the future.链接：http://www.sciencedirect.com/science/article/pii/S0167572902001000

This paper proposes the parametric modeling of the tool edge geometry through the application of free-knot B-splines that comprise three piecewise segments corresponding to the cutting edge profile and
15
the two tool faces. The transition points that demarcate the cutting edge from the tool faces are objectively and robustly identified by the adaptive placement of the knots that minimizes the residual error from fitting the B-spline to the tool profile data. On identification of the cutting edge, the edge profile is modeled by parametric quadratics to yield four geometrically relevant, contour-based parameters that characterize both symmetric and asymmetric honed edges.链接：http://www.sciencedirect.com/science/article/pii/S0141635913000482

During the past 20 years, it has become an extremely well researched field due to practical interest in air and water remediation, self-cleaning surfaces, and self-sterilizing surfaces. During the same period, there has also been a strong effort to use photocatalysis for light-assisted production of hydrogen. The fundamental aspects of photocatalysis on the most studied photocatalyst, titania, are still being actively researched and have recently become quite well understood. The mechanisms by which certain types of organic compounds are decomposed completely to carbon dioxide and water, for example, have been delineated. However, certain aspects, such as the photo-induced wetting phenomenon, remain controversial, with some groups maintaining that the effect is a simple one in which organic contaminants are decomposed, while other groups maintain that there are additional effects in which the intrinsic surface properties are modified by light. During the past several years, powerful tools such as surface spectroscopic techniques and scanning probe techniques performed on single crystals in ultra-high vacuum, and ultrafast pulsed laser spectroscopic techniques have been brought to bear on these problems, and new insights have become possible. Quantum chemical calculations have also provided new insights. New materials have recently been developed based on titania, and the sensitivity to visible light has improved. The new information available is staggering, but we hope to offer an overview of some of the recent highlights, as well as to review some of the origins and indicate some possible new directions.链接：http://www.sciencedirect.com/science/article/pii/S0167572908000757

The main sources exploited are two marine crustaceans, shrimp and crabs. Our objective is to appraise the state of the art concerning this polysaccharide: its morphology in the native solid state, methods of identification and characterization and chemical modifications, as well as the difficulties in utilizing and processing it for selected applications. We note the important work of P. Austin, S. Tokura and S. Hirano, who have contributed to the applications development of chitin, especially in fiber form. Then, we discuss chitosan, the most important derivative of chitin, outlining the best techniques to characterize it and the main problems encountered in its utilization. Chitosan, which is soluble in acidic aqueous media, is used in many applications (food, cosmetics, biomedical and pharmaceutical applications). We

It can be produced by micro-mechanical exfoliation of highly ordered pyrolytic graphite, epitaxial growth, chemical vapor deposition, and the reduction of graphene oxide (GO). The first three methods can produce graphene with a relatively perfect structure and excellent properties, while in comparison, GO has two important characteristics: (1) it can be produced using inexpensive graphite as raw material by cost-effective chemical methods with a high yield, and (2) it is highly hydrophilic and can form stable aqueous colloids to facilitate the assembly of macroscopic structures by simple and cheap solution processes, both of which are important to the large-scale uses of graphene. A key topic in the research and applications of GO is the reduction, which partly restores the structure and properties of graphene. Different reduction processes result in different properties of reduced GO (rGO), which in turn affect the final performance of materials or devices composed of rGO. In this contribution, we review the state-of-art status of the reduction of GO on both techniques and mechanisms. The development in this field will speed the applications of graphene.链接：http://www.sciencedirect.com/science/article/pii/S0008622311008967

摘要：Carbon nanotubes have long been recognized as the stiffest and strongest man-made material known to date. In addition, their high electrical conductivity has roused interest in the area of electrical appliances and communication related applications. However, due to their miniscule size, the excellent properties of these nanostructures can only be exploited if they are homogeneously embedded into light-weight matrices as those offered by a whole series of engineering polymers. We review the present state of polymer nanocomposites research in which the fillers are carbon nanotubes. In order to enhance their chemical affinity to engineering polymer matrices, chemical modification of the graphitic sidewalls and tips is necessary. In this review, an extended account of the various chemical strategies for grafting polymers onto carbon nanotubes and the manufacturing of carbon nanotube/polymer nanocomposites is given. The mechanical and electrical properties to date of a whole range of nanocomposites of various carbon nanotube contents are also reviewed in an attempt to facilitate progress in this emerging area.链接：http://www.sciencedirect.com/science/article/pii/S0079670009000859

The storage of latent heat provides a greater density of energy storage with a smaller temperature difference between storing and releasing heat than the sensible heat storage method. Many different groups of materials have been investigated during the technical evolution of PCMs, including inorganic systems (salt and salt hydrates), organic compounds such as paraffins or fatty acids and polymeric materials, e.g. poly(ethylene glycol). Historically, the relationships between the structure and the energy storage properties of a material have been studied to provide an understanding of the heat accumulation/emission mechanism governing the material’s imparted energy storage characteristics.
This paper reviews the present state of the art of PCMs for thermal energy storage applications and provides an insight into recent efforts to develop new PCMs with enhanced performance and safety. Specific attention is given to the improvement of thermal conductivity, encapsulation methods and shape stabilization procedures. In addition, the flame retarding properties and performance are discussed. The wide range of PCM applications in the construction, electronic, biomedical, textile and automotive industries is presented and future research directions are indicated.

A distinction is made between the film-forming techniques that are used currently such as spincoating, doctor blading and casting and the, from a processing point of view, more desirable film-forming techniques such as slot-die coating, gravure coating, knife-over-edge coating, off-set coating, spray coating and printing techniques such as ink jet printing, pad printing and screen printing. The former are used almost exclusively and are not suited for high-volume production whereas the latter are highly suited, but little explored in the context of polymer solar cells. A further distinction is made between printing and coating when a film is formed. The entire process leading to polymer solar cells is broken down into the individual steps and the available techniques and materials for each step are described with focus on the particular advantages and disadvantages associated with each case.链接：http://www.sciencedirect.com/science/article/pii/S0927024808003486

摘 要 ： Poly(lactic-co-glycolic acid) (PLGA) is one of the most successfully developed biodegradable polymers. Among the different polymers developed to formulate polymeric nanoparticles, PLGA has attracted considerable attention due to its attractive properties: (i) biodegradability and biocompatibility, (ii) FDA and European Medicine Agency approval in drug delivery systems for parenteral administration, (iii) well described formulations and methods of production adapted to various types of drugs e.g. hydrophilic or hydrophobic small molecules or macromolecules, (iv) protection of drug from degradation, (v) possibility of sustained release, (vi) possibility to modify surface properties to provide stealthness and/or better interaction with biological materials and (vii) possibility to target nanoparticles to specific organs or cells. This review presents why PLGA has been chosen to design nanoparticles as drug delivery systems in various biomedical applications such as vaccination, cancer, inflammation and other diseases. This review focuses on the understanding of specific characteristics exploited by PLGA-based nanoparticles to target a specific organ or tissue or specific cells.链接：http://www.sciencedirect.com/science/article/pii/S0168365912000752

The mixed-valence polyoxometallates method was carried out in water, an environmentally-friendly solvent. Solutions of AgNO3 containing glucose and starch in water gave starch-protected Ag NPs, which could be integrated into medical applications. Tollens process involves the reduction of Ag(NH3)2+ by saccharides forming Ag NP films with particle sizes from 50–200 nm, Ag hydrosols with particles in the order of 20–50 nm, and Ag colloid particles of different shapes. The reduction of Ag(NH3)2+ by HTAB (n-hexadecyltrimethylammonium bromide) gave Ag NPs of different morphologies: cubes, triangles, wires, and aligned wires. Ag NPs synthesis by irradiation of Ag+ ions does not involve a reducing agent and is an appealing procedure. Eco-friendly bio-organisms in plant extracts contain proteins, which act as both reducing and capping agents forming stable and shape-controlled Ag NPs. The synthetic procedures of polymer-Ag and TiO2–Ag NPs are also given. Both Ag NPs and Ag NPs modified by surfactants or polymers showed high antimicrobial activity against Gram-positive and Gram-negative bacteria. The mechanism of the Ag NP bactericidal activity is discussed in terms of Ag NP interaction with the cell membranes of bacteria. Silver-containing filters are shown to have antibacterial properties in water and air purification. Finally, human and environmental implications of Ag NPs to the ecology of aquatic environment are briefly discussed.链接：http://www.sciencedirect.com/science/article/pii/S0168365912000752

20
biodegradable polymeric materials for biomedical applications. Degradable polymeric biomaterials are preferred candidates for developing therapeutic devices such as temporary prostheses, three-dimensional porous structures as scaffolds for tissue engineering and as controlled/sustained release drug delivery vehicles. Each of these applications demands materials with specific physical, chemical, biological, biomechanical and degradation properties to provide efficient therapy. Consequently, a wide range of natural or synthetic polymers capable of undergoing degradation by hydrolytic or enzymatic route are being investigated for biomedical applications. This review summarizes the main advances published over the last 15 years, outlining the synthesis, biodegradability and biomedical applications of biodegradable synthetic and natural polymers.链接：http://www.sciencedirect.com/science/article/pii/S0079670007000664
25. 标题：Surface modification of inorganic nanoparticles for development of organic-inorganic nanocomposites-A review • Review article 出处：Progress in Polymer Science, Volume 38, Issue 8, August 2013, Pages 1232-1261作者：Kango, S.; Kalia, S.; Celli, A.; Njuguna, J.; Habibi, Y.; Kumar, R. 摘要：Nanoparticles and nanocomposites are used in a wide range of applications in various fields, such as medicine, textiles, cosmetics, agriculture, optics, food packaging, optoelectronic devices, semiconductor devices, aerospace, construction and catalysis. Nanoparticles can be incorporated into polymeric nanocomposites. Polymeric nanocomposites consisting of inorganic nanoparticles and organic polymers represent a new class of materials that exhibit improved performance compared to their microparticle counterparts. It is therefore expected that they will advance the field of engineering applications. Incorporation of inorganic nanoparticles into a polymer matrix can significantly affect the properties of the matrix. The resulting composite might exhibit improved thermal, mechanical, rheological, electrical, catalytic, fire retardancy and optical properties. The properties of polymer composites depend on the type of nanoparticles that are incorporated, their size and shape, their concentration and their interactions with the polymer matrix. The main problem with polymer nanocomposites is the prevention of particle aggregation. It is difficult to produce monodispersed nanoparticles in a polymer matrix because nanoparticles agglomerate due to their specific surface area and volume effects. This problem can be overcome by modification of the surface of the inorganic particles. The modification improves the interfacial interactions between the inorganic particles and the polymer matrix. There are two ways to modify the surface of inorganic particles. The first is accomplished through surface absorption or reaction with small molecules, such as silane coupling agents, and the second method is based on grafting polymeric molecules through covalent bonding to the hydroxyl groups existing on the particles. The advantage of the second procedure over the first lies in the fact that the polymer-grafted particles can be designed with the desired properties through a proper selection of the species of the grafting monomers and the choice of grafting conditions.链接：http://www.sciencedirect.com/science/article/pii/S0079670007000664

What it will not be is an incremental advance on 4G. The previous four generations of cellular technology have each been a major paradigm shift that has broken backward compatibility. Indeed, 5G will need to be a paradigm shift that includes very high carrier frequencies with massive bandwidths, extreme base station and device densities, and unprecedented numbers of antennas. However, unlike the previous four generations, it will also be highly integrative: tying any new 5G air interface and spectrum together with LTE and WiFi to provide universal high-rate coverage and a seamless user experience. To support this, the core network will also have to reach unprecedented levels of flexibility and intelligence, spectrum regulation will need to be rethought and improved, and energy and cost efficiencies will become even more critical considerations. This paper discusses all of these topics, identifying key challenges for future research and preliminary 5G standardization activities, while providing a comprehensive overview of the current literature, and in particular of the papers appearing in this special issue.

The term big data was coined to capture the meaning of this emerging trend. In addition to its sheer volume, big data also exhibits other unique
22
characteristics as compared with traditional data. For instance, big data is commonly unstructured and require more real-time analysis. This development calls for new system architectures for data acquisition, transmission, storage, and large-scale data processing mechanisms. In this paper, we present a literature survey and system tutorial for big data analytics platforms, aiming to provide an overall picture for nonexpert readers and instill a do-it-yourself spirit for advanced audiences to customize their own big-data solutions. First, we present the definition of big data and discuss big data challenges. Next, we present a systematic framework to decompose big data systems into four sequential modules, namely data generation, data acquisition, data storage, and data analytics. These four modules form a big data value chain. Following that, we present a detailed survey of numerous approaches and mechanisms from research and industry communities. In addition, we present the prevalent Hadoop framework for addressing big data challenges. Finally, we outline several evaluation benchmarks and potential research directions for big data systems.

However, with an explosion of wireless mobile devices and services, there are still some challenges that cannot be accommodated even by 4G, such as the spectrum crisis and high energy consumption. Wireless system designers have been facing the continuously increasing demand for high data rates and mobility required by new wireless applications and therefore have started research on fifth generation wireless systems that are expected to be deployed beyond 2020. In this article, we propose a potential cellular architecture that separates indoor and outdoor scenarios, and discuss various promising technologies for 5G wireless communication systems, such as massive MIMO, energy-efficient communications, cognitive radio networks, and visible light communications. Future challenges facing these potential technologies are also discussed.

However, multi-user MIMO, as originally envisioned, with roughly equal numbers of service antennas and terminals and frequency-division duplex operation, is not a scalable technology. Massive MIMO (also known as large-scale antenna systems, very large MIMO, hyper MIMO, full-
23
dimension MIMO, and ARGOS) makes a clean break with current practice through the use of a large excess of service antennas over active terminals and time-division duplex operation. Extra antennas help by focusing energy into ever smaller regions of space to bring huge improvements in throughput and radiated energy efficiency. Other benefits of massive MIMO include extensive use of inexpensive low-power components, reduced latency, simplification of the MAC layer, and robustness against intentional jamming. The anticipated throughput depends on the propagation environment providing asymptotically orthogonal channels to the terminals, but so far experiments have not disclosed any limitations in this regard. While massive MIMO renders many traditional research problems irrelevant, it uncovers entirely new problems that urgently need attention: the challenge of making many low-cost low-precision components that work effectively together, acquisition and synchronization for newly joined terminals, the exploitation of extra degrees of freedom provided by the excess of service antennas, reducing internal power consumption to achieve total energy efficiency reductions, and finding new deployment scenarios. This article presents an overview of the massive MIMO concept and contemporary research on the topic.

There is, however, little knowledge about cellular mm-wave propagation in densely populated indoor and outdoor environments. Obtaining this information is vital for the design and operation of future fifth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation for new mm-wave cellular systems, methodology, and hardware for measurements and offer a variety of measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices.

Cloud services are delivered from data centers located throughout the world. Cloud computing facilitates its consumers by providing virtual resources via internet. General example of cloud services is Google apps, provided by Google and Microsoft SharePoint. The rapid growth in field of “cloud computing” also increases severe security concerns. Security has remained a constant issue for Open Systems and internet, when we are talking about security cloud really suffers. Lack of security is the only hurdle in wide adoption of cloud computing. Cloud computing is surrounded by many security issues like securing data, and examining the utilization of cloud by the cloud computing vendors. The wide

acceptance www has raised security risks along with the uncountable benefits, so is the case with cloud computing. The boom in cloud computing has brought lots of security challenges for the consumers and service providers. How the end users of cloud computing know that their information is not having any availability and security issues? Every one poses, Is their information secure? This study aims to identify the most vulnerable security threats in cloud computing, which will enable both end users and vendors to know about the key security threats associated with cloud computing. Our work will enable researchers and security professionals to know about users and vendors concerns and critical analysis about the different security models and tools proposed.8.标题：Cloud Networks: Enhancing Performance and Resiliency作者：Secci, S. ; Murugesan, S. 出处:Computer Volume: 47 Issue: 10 Date : Oct. 2014 Page(s): 82 - 85 DOI: 10.1109/MC.2014.277 摘要：New and ever more sophisticated cloud applications pose key challenges for improving cloud network performance and resiliency.

The METIS overall approach toward 5G builds on the evolution of existing technologies complemented by new radio concepts that are designed to meet the new and challenging requirements of use cases today's radio access networks cannot support. The integration of these new radio concepts, such as massive MIMO, ultra dense networks, moving networks, and device-to-device, ultra reliable, and massive machine communications, will allow 5G to support the expected increase in mobile data volume while broadening the range of application domains that mobile communications can support beyond 2020. In this article, we describe the scenarios identified for the purpose of driving the 5G research direction. Furthermore, we give initial directions for the technology components (e.g., link level components, multinode/multiantenna, multi-RAT, and multi-layer networks and spectrum handling) that will allow the fulfillment of the requirements of the identified 5G scenarios.

摘要：A general non-parametric technique is proposed for the analysis of a complex multimodal feature space and to delineate arbitrarily shaped clusters in it. The basic computational module of the technique is an old pattern recognition procedure: the mean shift. For discrete data, we prove the convergence of a recursive mean shift procedure to the nearest stationary point of the underlying density function and, thus, its utility in detecting the modes of the density. The relation of the mean shift procedure to the Nadaraya-Watson estimator from kernel regression and the robust M-estimators; of location is also established. Algorithms for two low-level vision tasks discontinuity-preserving smoothing and image segmentation - are described as applications. In these algorithms, the only user-set parameter is the resolution of the analysis, and either gray-level or color images are accepted as input. Extensive experimental results illustrate their excellent performance

If x is known to be compressible by transform coding with a known transform, and we reconstruct via the nonlinear procedure defined here, the number of measurements n can be dramatically smaller than the size m. Thus, certain natural classes of images with m pixels need only n=O(m1/4log5/2(m)) nonadaptive nonpixel samples for faithful recovery, as opposed to the usual m pixel samples. More specifically, suppose x has a sparse representation in some orthonormal basis (e.g., wavelet, Fourier) or tight frame (e.g., curvelet, Gabor)-so the coefficients belong to an lscrp ball for 0<ples1. The N most important coefficients in that expansion allow reconstruction with lscr2 error O(N1/2-1p/). It is possible to design n=O(Nlog(m)) nonadaptive measurements allowing reconstruction with accuracy comparable to that attainable with direct knowledge of the N most important coefficients. Moreover, a good approximation to those N important coefficients is extracted from the n measurements by solving a linear program-Basis Pursuit in signal processing. The nonadaptive measurements have the character of "random" linear combinations of basis/frame elements. Our results use the notions of optimal recovery, of n-widths, and information-based complexity. We estimate the Gel'fand n-widths of lscrp balls in high-dimensional Euclidean space in the case 0<ples1, and give a criterion identifying near- optimal subspaces for Gel'fand n-widths. We show that "most" subspaces are near-optimal, and show that convex optimization (Basis Pursuit) is a near-optimal way to extract information derived from these near-optimal subspaces

26
equipping cellular base stations (BSs) with a very large number of antennas, and has been shown to potentially allow for orders of magnitude improvement in spectral and energy efficiency using relatively simple (linear) processing. In this paper, we present a comprehensive overview of state-of-the-art research on the topic, which has recently attracted considerable attention. We begin with an information theoretic analysis to illustrate the conjectured advantages of massive MIMO, and then we address implementation issues related to channel estimation, detection and precoding schemes. We particularly focus on the potential impact of pilot contamination caused by the use of non-orthogonal pilot sequences by users in adjacent cells. We also analyze the energy efficiency achieved by massive MIMO systems, and demonstrate how the degrees of freedom provided by massive MIMO systems enable efficient single-carrier transmission. Finally, the challenges and opportunities associated with implementing massive MIMO in future wireless communications systems are discussed.

The key ideas for each technology are described, along with their potential impact on 5G and the research challenges that remain.
14.标题：Agent-Based Cloud Computing作者：Kwang Mong Sim 出处：Services Computing, IEEE Transactions on Volume: 5 Issue: 4 Date : Fourth Quarter 2012 Page(s): 564 - 577 DOI: 10.1109/TSC.2011.52 摘要：Agent-based cloud computing is concerned with the design and development of software agents for bolstering cloud service discovery, service negotiation, and service composition. The significance of this work is introducing an agent-based paradigm for constructing software tools and testbeds for cloud resource management. The novel contributions of this work include: 1) developing Cloudle: an agent-based search engine for cloud service discovery, 2) showing that agent-based negotiation mechanisms can be effectively adopted for bolstering cloud service negotiation and cloud commerce, and 3) showing that agent-based cooperative problem-solving techniques can be effectively adopted for automating cloud service composition. Cloudle consists of 1) a service discovery agent that consults a cloud ontology for determining the similarities between providers' service specifications and consumers' service requirements, and 2) multiple cloud crawlers for building its database of services. Cloudle supports three types of reasoning: similarity reasoning, compatibility reasoning, and numerical reasoning. To support cloud commerce, this work devised a
27
complex cloud negotiation mechanism that supports parallel negotiation activities in interrelated markets: a cloud service market between consumer agents and broker agents, and multiple cloud resource markets between broker agents and provider agents. Empirical results show that using the complex cloud negotiation mechanism, agents achieved high utilities and high success rates in negotiating for cloud resources. To automate cloud service composition, agents in this work adopt a focused selection contract net protocol (FSCNP) for dynamically selecting cloud services and use service capability tables (SCTs) to record the list of cloud agents and their services. Empirical results show that using FSCNP and SCTs, agents can successfully compose cloud services by autonomously selecting services.15.标题：A Survey of Software-Defined Networking: Past, Present, and Future of Programmable Networks作者：Nunes, B.A.A. ; Mendonca, M. ; Xuan-Nam Nguyen ; Obraczka, K. ; Turletti, T. 出处：Communications Surveys & Tutorials, IEEE Volume: 16 Issue: 3 Date : Third Quarter 2014 Page(s): 1617 - 1634 DOI: 10.1109/SURV.2014.012214.00180 摘要：The idea of programmable networks has recently re-gained considerable momentum due to the emergence of the Software-Defined Networking (SDN) paradigm. SDN, often referred to as a "radical new idea in networking", promises to dramatically simplify network management and enable innovation through network programmability. This paper surveys the state-of-the-art in programmable networks with an emphasis on SDN. We provide a historic perspective of programmable networks from early ideas to recent developments. Then we present the SDN architecture and the OpenFlow standard in particular, discuss current alternatives for implementation and testing of SDN-based protocols and services, examine current and future SDN applications, and explore promising research directions based on the SDN paradigm.

DOI: 10.1109/TIP.2003.819861 摘要：Objective methods for assessing perceptual image quality traditionally attempted to quantify the visibility of errors (differences) between a distorted image and a reference image using a variety of known properties of the human visual system. Under the assumption that human visual perception is highly adapted for extracting structural information from a scene, we introduce an alternative complementary framework for quality assessment based on the degradation of structural information. As a specific example of this concept, we develop a structural similarity index and demonstrate its promise through a set of intuitive examples, as well as comparison to both subjective ratings and state-of-the-art objective methods on a database of images compressed with JPEG and JPEG2000. A MATLAB implementation of the proposed algorithm is available online at http://www.cns.nyu.edu/∼lcv/ssim/.

Building a general architecture for the IoT is hence a very complex task, mainly because of the extremely large variety of devices, link layer technologies, and services that may be involved in such a system. In this paper, we focus specifically to an urban IoT system that, while still being quite a broad category, are characterized by their specific application domain. Urban IoTs, in fact, are designed to support the Smart City vision, which aims at exploiting the most advanced communication technologies to support added-value services for the administration of the city and for the citizens. This paper hence provides a comprehensive survey of the enabling technologies, protocols, and architecture for an urban IoT. Furthermore, the paper will present and discuss the technical solutions and best-practice guidelines adopted in the Padova Smart City project, a proof-of-concept deployment of an IoT island in the city of Padova, Italy, performed in collaboration with the city municipality.

The success of the approach depends on the definition of a comprehensive set of goals for the computation of edge points. These goals must be precise enough to delimit the desired behavior of the detector while making minimal assumptions about the form of the solution. We define detection and localization criteria for a class of edges, and present mathematical forms for these criteria as functionals on the operator impulse response. A third criterion is then added to ensure that the detector has only one response to a single
29
edge. We use the criteria in numerical optimization to derive detectors for several common image features, including step edges. On specializing the analysis to step edges, we find that there is a natural uncertainty principle between detection and localization performance, which are the two main goals. With this principle we derive a single operator shape which is optimal at any scale. The optimal detector has a simple approximate implementation in which edges are marked at maxima in gradient magnitude of a Gaussian-smoothed image. We extend this simple detector using operators of several widths to cope with different signal-to-noise ratios in the image. We present a general method, called feature synthesis, for the fine-to-coarse integration of information from operators at different scales. Finally we show that step edge detector performance improves considerably as the operator point spread function is extended along the edge.

Botnets, well-organized distributed network attacks, consist of a large number of bots that generate huge volumes of spam or launch Distributed Denial of Service (DDoS) attacks on victim hosts. New emerging botnet attacks degrade the status of Internet security further. To address these problems, a practical collaborative network security management system is proposed with an effective collaborative Unified Threat Management (UTM) and traffic probers. A distributed security overlay network with a centralized security center leverages a peer-to-peer communication protocol used in the UTMs collaborative module and connects them virtually to exchange network events and security rules. Security functions for the UTM are retrofitted to share security rules. In this paper, we propose a design and implementation of a cloud-based security center for network security forensic analysis. We propose using cloud storage to keep collected traffic data and then processing it with cloud computing platforms to find the malicious attacks. As a practical example, phishing attack forensic analysis is presented and the required computing and storage resources are evaluated based on real trace data. The cloud-based security center can instruct each collaborative UTM and prober to collect events and raw traffic, send them back for deep analysis, and generate new security rules. These new security rules are enforced by collaborative UTM and the feedback events of such rules are returned to the security center. By this type of close-loop control, the collaborative network security management system can identify and address new distributed attacks more quickly and effectively.

摘要： The objective of this paper is comprehensive study related to 5G technology of mobile communication. Existing research work in mobile communication is related to 5G technology. In 5G, researches are related to the development of World Wide Wireless Web (WWWW), Dynamic Adhoc Wireless Networks (DAWN) and Real Wireless Communication.

The specification of a power-electronic interface is subject to requirements related not only to the renewable energy source itself but also to its effects on the power-system operation, especially where the intermittent energy source constitutes a significant part of the total system capacity. In this paper, new trends in power electronics for the integration of wind and photovoltaic (PV) power generators are presented. A review of the appropriate storage-system technology used for the integration of intermittent renewable energy sources is also introduced. Discussions about common and future trends in renewable energy systems based on reliability and maturity of each technology are presented
23.标题：Histograms of oriented gradients for human detection作者：Dalal, N. ; Triggs, B. 出处： Computer Vision and Pattern Recognition, 2005. CVPR 2005. IEEE Computer Society Conference on Volume: 1 Date : 25-25 June 2005 Page(s): 886 - 893 vol. 1 DOI: 10.1109/CVPR.2005.177 摘要：We study the question of feature sets for robust visual object recognition; adopting linear SVM based human detection as a test case. After reviewing existing edge and gradient based descriptors, we show experimentally that grids of histograms of oriented gradient (HOG) descriptors
31
significantly outperform existing feature sets for human detection. We study the influence of each stage of the computation on performance, concluding that fine-scale gradients, fine orientation binning, relatively coarse spatial binning, and high-quality local contrast normalization in overlapping descriptor blocks are all important for good results. The new approach gives near-perfect separation on the original MIT pedestrian database, so we introduce a more challenging dataset containing over 1800 annotated human images with a large range of pose variations and backgrounds.
24.标题：The role of small cells, coordinated multipoint, and massive MIMO in 5G作者：Jungnickel, V. ; Manolakis, K. ; Zirwas, W. ; Panzner, B. ; Braun, V. ; Lossow, M. ; Sternad, M. ; Apelfro ̈jd, R. ; Svensson, T. 出处：Communications Magazine, IEEE Volume: 52 Issue: 5 Date : May 2014 Page(s): 44 - 51 DOI: 10.1109/MCOM.2014.6815892 摘要：5G will have to support a multitude of new applications with a wide variety of requirements, including higher peak and user data rates, reduced latency, enhanced indoor coverage, increased number of devices, and so on. The expected traffic growth in 10 or more years from now can be satisfied by the combined use of more spectrum, higher spectral efficiency, and densification of cells. The focus of the present article is on advanced techniques for higher spectral efficiency and improved coverage for cell edge users. We propose a smart combination of small cells, joint transmission coordinated multipoint (JT CoMP), and massive MIMO to enhance the spectral efficiency with affordable complexity. We review recent achievements in the transition from theoretical to practical concepts and note future research directions. We show in measurements with macro-plus-smallcell scenarios that spectral efficiency can be improved by flexible clustering and efficient user selection, and that adaptive feedback compression is beneficial to reduce the overhead significantly. Moreover, we show in measurements that fast feedback reporting combined with advanced channel prediction are able to mitigate the impairment effects of JT CoMP.

The AAMAS conference series was initiated in 2002 by merging three highly respected meetings: the International Conference on Multi-Agent Systems (ICMAS); the International Workshop on Agent Theories, Architectures, and Languages (ATAL); and the International Conference on Autonomous Agents (AA).
The aim of the joint conference is to provide a single, high-profile, internationally respected archival forum for scientific research in the theory and practice of autonomous agents and multiagent systems.Information for Authors
AAMAS-15 encourages the submission of analytical, empirical, methodological, technological, and perspective papers. Authors are requested to pay particular attention to discussing how their work relates to the state of the art in autonomous agents and multiagent systems research, as evidenced in, for example, previous editions of AAMAS and related conferences. All submissions will be rigorously peer reviewed and evaluated on the basis of the overall quality of their technical contribution, including criteria such as originality, soundness, relevance, significance, quality of presentation, and understanding of the state of the art.AAMAS 2015, the fourteenth conference in the AAMAS series, seeks the submission of high-quality papers. The length of each paper is limited to 8 pages excluding the bibliographic references, except for papers submitted to the Blue Sky Ideas track, which are limited to 4 pages in length including the references. Reviewing will be double-blind, so authors must avoid including anything in their papers that can be used to identify them. Particular attention should be given to the way previous work is referred to; other frequent sources of breach of anonymity are the acknowledgements, project names, and links to supplementary material on the Web. Papers that are over the page limit or identify the authors may be rejected without reviewing. Please note that submitting an abstract is required to submit a full paper. However, the abstracts will not be reviewed and full papers must be submitted for the review process to begin. All work must be original, i.e., it must not have appeared in the proceedings of an archival conference, journal, or book, and may not be under review for another archival conference or journal. In addition to submissions in the main track, AAMAS 2015 will be soliciting submissions to four special tracks: (1) Innovative Applications, (2) Robotics, (3) Virtual Agents and Humans, and (4) Blue Sky Ideas. The review process for the special tracks will be similar to the main track, but with program committee members specially selected for each track.

4. 会议名称：3rd International Conference on Buckling and Postbuckling Behaviour of Composite Laminated Shell Structures with DESICOS Workshop会议时间：25 - 27 March 2015会议地点：Location: Braunschweig, Germany会议简介： The project DESICOS (New Robust DESign Guideline for Imperfection Sensitive COmposite Launcher Structures) is a Level 1 Project within the 7th Framework Programme (No. 282522) and will run for 3 years (February 2012 – January 2015).
The Space industry demand for lighter and cheaper launcher transport systems. DESICOS contributes to these aims by a new design approach for imperfection sensitive composite launcher structures, exploiting the worst imperfection idea efficiently: the Single Perturbation Load Approach. Currently, imperfection sensitive shell structures prone to buckling are designed according the NASA SP 8007 guideline using the conservative lower bound curve. The guideline dates from 1968, and the structural behaviour of composite material is not considered appropriately, in particular since the imperfection sensitivity of shells made from such materials depends on the lay-up design. The buckling loads of CFRP structures may vary by a factor of about 3 just by changing the lay-up. This is not considered in the NASA SP 8007, which allows designing only so called "black metal" structures. Here is a high need for a new precise and fast design approach for imperfection sensitive composite structures which allows significant reduction of structural weight and design cost. For most relevant architectures of cylindrical and conical launcher structures (monolithic, sandwich - without and with holes) DESICOS will investigate a combined methodology from the Single Perturbation Load approach and a specific stochastic approach which guarantees an effective and robust design. A recent investigation demonstrated, that an axially loaded unstiffened cylinder, which is disturbed by a large enough single perturbation load, is leading directly to the design buckling load 45% higher compared with the respective NASA SP 8007 design. All results will be summarized in a handbook for the design imperfection sensitive composite structures. The potential will be
38
demonstrated within different driven use cases.论文提交：http://www.desicos.eu/

11. 会议名称：7th International Conference on Recent Advances in Space Technologies – RAST 2015会议时间：16 - 19 June 2015会议地点：Location: Istanbul, Turkey会议简介： Preamble: Nontraditional space initiatives have been emerging in recent years from the private sector, with seemingly exotic objectives such as space tourism and asteroid mining. They are indicative of a new level of maturity and innovation in space technology and understanding. These developments have set the stage for the seventh RAST Conference (RAST2015), for which the theme was decided as "EMERGING PRIVATE SPACE". RAST2015 will be held on 16-19 June 2015 again in Istanbul. RAST Conferences are open to all areas of space although each conference tries to focus on its specific theme as well.
Objectives: Commercial space has been around for several decades, in space communications, Earth observation and launch services. However, other commercial space initiatives have been emerging recently, with completely different and "out of this World" goals. Space tourism, asteroid mining and certain curiosity driven objectives are prime areas of those initiatives. In addition to technological feasibility, there are a number of other issues which require careful analysis. While entrepreneurs may be mostly concerned with financial, operational and market viability, governments and international institutions must be prepared to deal with legal and regulatory matters. Then there are the physiological and psychological issues regarding humans in space. International space law will need new interpretations and extensions to cover probable disputes which are already being pronounced, such as unrestricted access to space resources.RAST2015 has the main objective of providing a forum for the presentation and review of recent developments in private and nontraditional space initiatives, that is, developing and using space technologies for objectives which have hitherto been considered exotic or unconventional, including new ways of accessing space with humans or robots. It has always been the wish and the goal of the organizers to make RAST 2015 a premier event in space technology developments especially those on the way to near future deployment and of interest to a large part of the space community.
41
Participants: The conference should be attractive for everyone interested in new, exotic and extravagant space developments, including those from universities, research organizations, space companies, government agencies, relevant international institutions, as well as media and the general public. The conference should serve as an opportunity for networking and fruitful exchange with fellow participants on topics of mutual interest.论文提交：http://www.rast.org.tr/index.html

14. 会议名称：22nd AIAA Lighter-Than-Air Systems Technology Conference会议时间：22-26 June 2015 D会议地点：allas, Texas会议简介：Interest in the potential of lighter-than-air (LTA) systems to meet modern requirements continues to grow as fuel prices and the cost of conventional aircraft transportation infrastructures increase. An added incentive to airship and aerostat development comes from the worldwide concern over the negative environmental effects of jet aircraft on the global climate. LTA systems have become the subject of renewed interest due to their unique qualities of low energy (propulsion) needs and significant static lift, which hold potential for commercial as well as intelligence, surveillance, and reconnaissance (ISR) missions. New hybrid LTA systems that incorporate a substantial degree of dynamic lift also offer great promise for providing additional air transportation services, and access to remote regions. At the same time, major advances are being made in the development of key enabling technologies essential to the creation and operation of long endurance, unmanned LTA systems. These topics and more will be explored by industry experts at the 21st AIAA Lighter-Than-Air Systems Technology Conference.论文提交：http://www.aiaa-aviation.org/LTA/

5. 会议名称：Airborne ISR & C2 Battle Management会议时间：March 10-12, 2015会议地点：Thistle Marble Arch , London, United Kingdom会议简介：During our inaugural AISR and C2BM conference earlier this year, nobody could have predicted the operational challenges currently facing NATO and partner nations, with the rapid rise to prominence of ISIS and the dramatic situation in Eastern Europe. The importance of accurate and timely intelligence provision and dissemination cannot be understated, but nor can the dangers of a reactionary approach to strategic planning. Consequently, AISR&C2BM will pose the question “What’s next for Joint ISR” - for NATO as an organisation, for individual NATO states and for non-member partner nations - examining operational demands, desired capabilities and asset sustainment/support over the next five years.
The aim: To deliver a comprehensive assessment from leading NATO powers and partner nations on the challenges and opportunities for ISR provision beyond the current headlines, in order to provide insight into the medium-term actions to achieve a tangible step-change in co-operation and
49
capability.Take a front row seat as leading military experts explore how a proliferation of ISR assets in the
past decade has led to the need for streamlined Process Exploitation and Dissemination to maximise collected data for informed decision making, as well as examining the complexities of working with non-traditional partners and the limitations of interoperability and intelligence sharing.论文提交：http://www.airborneisrandbmc2.com/
6. 会议名称：Integrated Air and Missile Defence会议时间：March 16-18, 2015会议地点：Seville, Spain会议简介： IAMD is essential to the territorial integrity of many states in the modern world. New requirements are driving states to upgrade the capability or operation of their Air Defence units. However such modernisation raises concerns and challenges with regards to the integration of new and old assets within an effective shield against airborne threats. The growing variety of such threats,from slow and low UAVS, to Rockets and Artillery, to ballistic missiles, increases the need to ensure effective integration of protective assets.
In official partnership with the Spanish Air Defence Regiment, Integrated Air and Missile Defence 2015 will take place at the Air Defence HQ in Sevilla, where you will also experience a site tour and live fire demonstration as part of the pre-conference day. The tour of the base will enable all attendees to gain a first-hand insight into the daily operation

7. 会议名称：Lightweight Tactical Vehicle Summit会议时间：March 16-18, 2015会议地点：Detroit, Michigan会议简介：The limited military ground presence currently has allowed the US Army and US Marine Corps to give attention to a long withstanding issue: upgrading its light tactical vehicle fleet. Up until this point, much of what was done to the vehicle fleet during recent operations in Iraq and Afghanistan would be considered by most to be a temporary solution. As a result, the JLTV program is now headed for production, the AMPV program is approaching the final stages, the ULCV program is in pre-solicitation, and the HMMWV modernization initiative is on the horizon. However, not without challenges…. Identifying best value components is difficult to define
Assessing the full spectrum of sub contractor capabilities is easier said than done and, speed to market is essential as conflicts abroad percolate
Can you help achieve these objectives? Whether an active military stakeholder, an OEM spearheading the design, or a supplier with cutting edge solutions, don’t miss this rare opportunity to address the needs of not only the current projects but those coming in the near future by joining us for the Lightweight Tactical Vehicles Summit 2015.论文提交：http://www.lighttacticalvehiclesummit.com/

11. 会议名称：Smart Policing Summit 2015会议时间：April 27-29, 2015会议地点：Washington, DC会议简介： Limited staffing and budget cuts have pressured law enforcement agencies to adopt innovative methods in order to increase case-closure rates. Ensuring the safety of officers as well as the citizens they protect is the number one priority for law enforcement agencies. Finding the least expensive and most efficient way to do so is essentially the primary goal. Smart Policing involves defining and utilizing the paramount way to increase efficiency for law enforcement agencies. In this day and age, Chiefs of Police, Head Crime Analysts and Key Commanders of Law Enforcement agencies are pioneering a movement using technology, research and new policy.Join us as we explore the significant progress of Law Enforcement agencies in improving their case-closure rates and adopting new technologies. We are designing this conference to provide a platform that gives these ever-changing agencies the knowledge and tools they will need to reduce crime and increase efficiency.
With the advancements in technology, there is the introduction of Body-Worn Cameras, UAS and Gunshot Location Systems. The focus of leaders has shifted to making these technologies a part of the day-to-day operations of an officer, rather than getting in their way. However, as technology evolves, privacy and ease of use concerns arise.
If these issues are your priorities, you won’t want to miss IDGA’s Smart Policing Summit 2015 as we unravel the key issues in Law Enforcement and Smart Policing today and equip you with the tools you need to take on the new age of policing.论文提交：http://www.smartpolicingsummit.com/
12. 会议名称：Interoperable Open Architecture会议时间：April 29-1, 2015会议地点：London, UK会 议 简 介 ： The advantages of using interoperable open architecture for the development, procurement and use of technology are manifest in those programmes where it has been successfully rolled out. However, despite some successes within these US and UK programmes, there are still many that are not convinced that implementing such architectures is worth the required structural transformation, time and money.The Interoperable Open Architecture 2015 conference argues that common standards and open
52
architectures have the potential to revolutionise the cost and efficiency of procurement and will cover the following key areas:
The technical detail behind the development of standards and common requirements to enable ‘plug and play’
Implementing open architecture for new platforms and programmes: Lessons learned from the flagship efforts in the US and UK
The potential for transformation of defence procurement and the benefits and disadvantages of open architecture for both the military and industry communitiesEase of use and operator effectiveness on the front line
Cross-over practices and lessons-learned from the civilian sphere as open architectures are rolled out across land, air and naval systems
The benefits of open architectures also extend to the front line technology users. An interoperable open architecture can de-clutter a vehicle by enabling single screen control of multiple systems and common standards shared between allies can improve interoperability. While it might seem a pipe dream at the moment, a totally interoperable open architecture will eventually empower the operator to plug and play technology based on immediate mission parameters.Importantly interoperable open architecture is a concept that applies across different domains. Data model construction, architectural principles and layout are just some of the transferable elements that span any architecture effort whether it be for vehicles, planes or robotics.This year the conference will examine these principles whilst refocusing on the milestones reached in recent years.论文提交：http://www.ioaevent.com/

Consistent with literature, the optimal composition is Cu-poor and Zn-rich despite the precipitation of secondary phases (e.g., ZnS). Despite a very thin absorber thickness (similar to 600 nm), a reasonably good short-circuit current was obtained. Time-resolved photoluminescence measurements suggest a minority carrier-diffusion length on the order of several hundreds of nanometers and relatively good collection of photo-carriers across the entire absorber thickness.

Our attention is focused on the design of full-and reduced-order filters that guarantee the filtering error system to be asymptotically stable with a prescribed H-infinity performance. Sufficient conditions for the obtained filtering error system are proposed by applying an input-output approach and a two-term approximation method, which is employed to approximate the time-varying delay. The corresponding full-and reduced-order filter design is cast into a convex optimization problem, which can be efficiently solved by standard numerical algorithms. Finally, simulation examples are provided to illustrate the effectiveness of the proposed approaches.地址:Harbin Inst Technol, Harbin 150001, Peoples R China.Univ Glamorgan, Dept Comp & Math Sci, Pontypridd CF37 1DL, M Glam, Wales.Victoria Univ, Sch Sci & Engn, Melbourne, Vic 3000, Australia.Univ S Australia, Sch Math & Stat, Adelaide, SA 5001, Australia.Chongqing Univ, Sch Automat, Chongqing 400044, Peoples R China.电子邮件地址: [email protected]; [email protected]; [email protected]; [email protected]

However, the commercialization of Li/S battery still cannot be realized due to many problematic issues, including short cycle life, low cycling efficiency, poor safety and a high self-discharge rate. All these issues are related to the dissolution of lithium polysulfide (PS), the series of sulfur reduction intermediates, in liquid electrolyte and to resulting parasitic reactions with the lithium anode and electrolyte components. On the other hand, the dissolution of PS is essential for the performance of a Li/S cell. Without dissolution of PS, the Li/S cell cannot operate progressively due to the non-conductive nature of elemental sulfur and its reduction products. In this review article, we start with the fundamental chemistry of elemental sulfur in order to discuss the problems and solutions of liquid electrolyte Li/S battery.

In an effort to understand the benefits and drawbacks of existing methods, we empirically compare five state-of-the-art superpixel algorithms for their ability to adhere to image boundaries, speed, memory efficiency, and their impact on segmentation performance. We then introduce a new superpixel algorithm, simple linear iterative clustering (SLIC), which adapts a k-means clustering approach to efficiently generate superpixels. Despite its simplicity, SLIC adheres to boundaries as well as or better than previous methods. At the same time, it is faster and more memory efficient, improves segmentation performance, and is straightforward to extend to supervoxel generation.地址:Ecole Polytech Fed Lausanne, Sch Comp & Commun Sci, Images & Visual Representat Grp, CH-1015 Lausanne, Switzerland.ETH Swiss Fed Inst Technol, Zurich Light Microscopy Ctr, Inst Biochem, CH-4093 Zurich, Switzerland.Ecole Polytech Fed Lausanne, Comp Vis Lab, Sch Comp & Commun Sci, CH-1015 Lausanne, Switzerland.电子邮件地址: [email protected]; [email protected]; [email protected]; [email protected]; [email protected];[email protected]

摘要：This paper focuses on analyzing a new model transformation of discrete-time Takagi-Sugeno (T-S) fuzzy systems with time-varying delays and applying it to dynamic output feedback (DOF) controller design. A new comparison model is proposed by employing a new approximation for time-varying delay state, and then, a delay partitioning method is used to analyze the scaled small gain of this comparison model. A sufficient condition on discrete-time T-S fuzzy systems with time-varying delays, which guarantees the corresponding closed-loop system to be asymptotically stable and has an induced l(2) disturbance attenuation performance, is derived by employing the scaled small-gain theorem. Then, the solvability condition for the induced l(2) DOF control is also established, by which the DOF controller can be solved as linear matrix inequality optimization problems. Finally, examples are provided to illustrate the effectiveness of the proposed approaches.地址 :Harbin Inst Technol, Space Control & Inertial Technol Res Ctr, Harbin 150001, Peoples R China.Univ Glamorgan, Dept Comp & Math Sci, Pontypridd CF37 1DL, M Glam, Wales.Victoria Univ, Sch Sci & Engn, Melbourne, Vic 3030, Australia.Univ Adelaide, Sch Elect & Elect Engn, Adelaide, SA 5005, Australia.Chongqing Univ, Sch Automat, Chongqing 400044, Peoples R China.电子邮件地址: [email protected]; [email protected]; [email protected]; [email protected]

Here, we report a thin-film solar cell with solution-processed Cu(In,Ga)(S,Se)(2) (CIGS) absorber. The power conversion efficiency of 15.2% is the highest published value for a pure solution deposition technique for any photovoltaic absorber material and is on par with the best nonvacuum-processed CIGS devices. We compare the performance of our cell with a world champion vacuum-deposited CIGS cell and perform detailed characterization, such as biased quantum efficiency, temperature-dependent electrical measurement, time-resolved photoluminescence, and capacitance spectroscopy.

The nonlinear system is represented by a Takagi-Sugeno (T-S) fuzzy system, and a network-induced delay is incorporated in the modeling of the
60
connection link. In order to compensate for the network link effects and eliminate the tracking error, we employ some techniques mainly used in the predictive control and the integral control. Moreover, a quadratic cost function which includes terms related to the performance of the system and the actuating capacity is used. We assume that the lumped network-induced delay lies within a known set, and that the occurrence probability for each element in the set is known a priori. Then, the delay information will be incorporated into the delay-dependent tracking controllers. The parameters for the tracking controller are derived by solving an optimization problem. A networked inverted pendulum is used to illustrate the efficacy of the proposed design method.地址:Univ Victoria, Dept Mech Engn, Victoria, BC V8W 3P6, Canada.电子邮件地址: [email protected]; [email protected]; [email protected] 15.被引用次数: 51 题目 :A REVIEW ON THE KEY ISSUES FOR LITHIUM-ION BATTERY MANAGEMENT IN ELECTRIC VEHICLES 作者:LU LG; HAN XB; LI JQ; HUA JF; OUYANG MG 出处:J POWER SOURCES 226: 272-288 MAR 15 2013 摘要：Compared with other commonly used batteries, lithium-ion batteries are featured by high energy density, high power density, long service life and environmental friendliness and thus have found wide application in the area of consumer electronics. However, lithium-ion batteries for vehicles have high capacity and large serial-parallel numbers, which, coupled with such problems as safety, durability, uniformity and cost, imposes limitations on the wide application of lithium-ion batteries in the vehicle. The narrow area in which lithium-ion batteries operate with safety and reliability necessitates the effective control and management of battery management system. This present paper, through the analysis of literature and in combination with our practical experience, gives a brief introduction to the composition of the battery management system (BMS) and its key issues such as battery cell voltage measurement, battery states estimation, battery uniformity and equalization, battery fault diagnosis and so on, in the hope of providing some inspirations to the design and research of the battery management system.

The aim of this review paper is the investigation of the nanofluids' applications in solar thermal engineering systems. The shortage of fossil fuels and environmental considerations motivated the researchers to use alternative energy sources such as solar energy. Therefore, it is essential to enhance the efficiency and performance of the solar thermal systems. Nearly all of the former works conducted on the applications of nanofluids in solar energy is regarding their applications in collectors and solar water heaters. Therefore, a major part of this review paper allocated to the effects

of nanofluids on the performance of solar collectors and solar water heaters from the efficiency, economic and environmental considerations viewpoints. In addition, some reported works on the applications of nanofluids in thermal energy storage, solar cells, and solar stills are reviewed. Subsequently, some suggestions are made to use the nanofluids in different solar thermal systems such as photovoltaic/thermal systems, solar ponds, solar thermoelectric cells, and so on. Finally, the challenges of using nanofluids in solar energy devices are discussed. (C) 2012 Elsevier Ltd.

The sampling period considered here is assumed to be time-varying that switches between two different values in a random way with given probability. The addressed synchronization control problem is first formulated as an exponentially mean-square stabilization problem for a new class of dynamical networks that involve both the multiple probabilistic interval delays (MPIDs) and the sector-bounded nonlinearities (SBNs). Then, a novel Lyapunov functional is constructed to obtain sufficient conditions under which the dynamical network is exponentially mean-square stable. Both Gronwall's inequality and Jenson integral inequality are utilized to substantially simplify the derivation of the main results. Subsequently, a set of sampled-data synchronization controllers is designed in terms of the solution to certain matrix inequalities that can be solved effectively by using available software. Finally, a numerical simulation example is employed to show the effectiveness of the proposed sampled-data synchronization control scheme.地址:Donghua Univ, Sch Informat Sci & Technol, Shanghai 200051, Peoples R China.Brunel Univ, Dept Informat Syst & Comp, Uxbridge UB8 3PH, Middx, England.电子邮件地址: [email protected]; [email protected]; [email protected] 18.被引用次数: 46 题 目 :THE STABILITY OF ORGANIC SOLVENTS AND CARBON ELECTRODE IN NONAQUEOUS LI-O-2 BATTERIES 作者:XU W; HU JZ; ENGELHARD MH; TOWNE SA; HARDY JS; XIAO J; FENG J; HU MY; ZHANG J; DING F; GROSS ME; ZHANG JG 出处:J POWER SOURCES 215: 240-247 OCT 1 2012 摘要： The effects of six types of aprotic organic solvents on the discharge performance and discharge products in Li-O-2 batteries are systematically investigated. A large amount of Li2O2 is identified in the air electrodes discharged in glyme-based electrolytes, while only a small amount of
62
Li2O2 is detected in the air electrodes discharged in the electrolytes of nitrile, ionic liquid, phosphate, and sulfoxide. Li2CO3 and LiF are also found as byproducts whose compositions are related to the solvents. Li2CO3 is produced from oxidation and decomposition of the solvent, not from the oxidation of the carbon-based air electrode, as revealed by using a C-13-labeled carbon electrode and the solid-state C-13-magic angle spinning nuclear magnetic resonance technique. LiF in the discharge products can be attributed to the attack of superoxide radical anions to the Teflon binder and/or the F-containing imide salt. The formation of these byproducts will significantly reduce the Coulombic efficiency and cycle life of the Li-air batteries. Among the studied solvents, dibutyl diglyme is the suitable solvent for Li-O-2 batteries based on its overall properties. However, better electrolytes that can ensure the formation of Li2O2 but minimize other reaction products need to be further investigated for long cycling rechargeable Li-air batteries.

However, the high cost and energy requirements of current CO2 capture processes are major barriers to their use. This paper assesses the outlook for improved, lower-cost technologies for each of the three major approaches to CO2 capture, namely, post-combustion, pre-combustion and oxy-combustion capture. The advantages and limitations of each of method are discussed, along with the current status of projects and processes at various stages in the development cycle. We then review a variety of "roadmaps" developed by governmental and private-sector organizations to project the commercial roll-out and deployment of advanced capture technologies. For perspective, we also review recent experience with R&D programs to develop lower-cost technologies for SO2 and NOx capture at coal-fired power plants. For perspective on projected cost reductions for CO2 capture we further review past experience in cost trends for SO2 and NOx capture systems. The key insight for improved carbon capture technology is that achieving significant cost reductions will require not only a vigorous and sustained level of research and development (R&D), but also a substantial level of commercial deployment, which, in turn, requires a significant market for CO2 capture technologies. At present such a market does not yet exist. While various incentive programs can accelerate the development and deployment of improved CO2 capture systems, government actions that significantly limit CO2 emissions to the atmosphere ultimately are needed to realize substantial and sustained reductions in the future cost of CO2 capture.

The system measurements are collected through a lossy sensor network subject to randomly occurring quantization errors and randomly occurring packet dropouts.

Hartnoll摘要：The anomalous transport of important materials such as high-temperature superconductors and other ‘bad metals’ is not well understood theoretically. In an incoherent metal, transport is controlled by the collective diffusion of energy and charge rather than by quasiparticle or momentum relaxation. Here, we explore the possibility of a universal bound D ≳ ℏνF2/(kBT) on the underlying diffusion constants in an incoherent metal. Such a bound is loosely motivated by results from holographic duality, the uncertainty principle and measurements of diffusion in strongly interacting non-metallic systems. Metals close to saturating this bound are shown to have a linear-in-temperature resistivity with an underlying dissipative timescale matching that recently deduced from experimental data on a wide range of metals. This bound may therefore be responsible for the ubiquitous appearance of high-temperature regimes in metals with T-linear resistivity. To establish this calls for direct measurements of diffusive processes and of charge susceptibilities in incoherent metals.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3174.html

Yin, H. T. Quan & Kihwan Kim摘要：The Jarzynski equality relates the free-energy difference between two equilibrium states to the work done on a system through far-from-equilibrium processes—a milestone that builds on the pioneering work of Clausius and Kelvin. Although experimental tests of the equality have been performed in the classical regime, the quantum Jarzynski equality has not yet been fully verified owing to experimental challenges in measuring work and work distributions in a quantum system. Here, we report an experimental test of the quantum Jarzynski equality with a single 171Yb+ ion trapped in a harmonic potential. We perform projective measurements to obtain phonon distributions of the initial thermal state. We then apply a laser-induced force to the projected energy eigenstate and find transition probabilities to final energy eigenstates after the work is done. By varying the speed with which we apply the force from the equilibrium to the far-from-equilibrium regime, we verify the quantum Jarzynski equality in an isolated system.链接：http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys3197.html
3. 标 题 ： Identifying the ‘fingerprint’ of antiferromagnetic spin fluctuations in iron pnictide superconductors AOP 作者：M. P. Allan, Kyungmin Lee, A. W. Rost, M. H. Fischer, F. Massee, K. Kihou, C-H. Lee, A. Iyo, H. Eisaki, T-M. Chuang, J. C. Davis & Eun-Ah Kim摘要： Cooper pairing in the iron-based high-Tc superconductors1, 2, 3 is often conjectured to involve bosonic fluctuations. Among the candidates are antiferromagnetic spin fluctuations1, 4, 5 and d-orbital fluctuations amplified by phonons6, 7. Any such electron–boson interaction should alter the electron’s ‘self-energy’, and then become detectable through consequent modifications in the energy dependence of the electron’s momentum and lifetime8, 9, 10. Here we introduce a novel theoretical/experimental approach aimed at uniquely identifying the relevant fluctuations of iron-based superconductors by measuring effects of their self-energy. We use innovative quasiparticle interference (QPI) imaging11 techniques in LiFeAs to reveal strongly momentum-space anisotropic self-energy signatures that are focused along the Fe–Fe (interband scattering) direction, where the spin fluctuations of LiFeAs are concentrated. These effects coincide in energy with perturbations to the density of states N(ω) usually associated with the Cooper pairing interaction. We show that all the measured phenomena comprise the predicted QPI ‘fingerprint’ of a self-energy due to antiferromagnetic spin fluctuations, thereby distinguishing them as the predominant electron–boson interaction.链接：http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys3187.html

The length scale and softness of defects in liquid crystals allow the easy observation of charges, but it is difficult to control charge creation. Here we demonstrate full control over the creation, manipulation and analysis of topological charges that are pinned to a microfibre in a nematic liquid crystal. Oppositely charged pairs are created through the Kibble–Zurek mechanism10, 11 by applying a laser-induced local temperature
65
quench in the presence of symmetry-breaking boundaries. The pairs are long-lived, oppositely charged rings or points that either attract and annihilate, or form a long-lived, charge-neutral loop made of two segments with a fractional topological charge.链接：http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys3194.html

Goldman摘要：Sixty years ago, Karplus and Luttinger pointed out that quantum particles moving on a lattice could acquire an anomalous transverse velocity in response to a force, providing an explanation for the unusual Hall effect in ferromagnetic metals1. A striking manifestation of this transverse transport was then revealed in the quantum Hall effect2 where the plateaux depicted by the Hall conductivity were attributed to a topological invariant characterizing the Bloch bands: the Chern number3. Until now, topological transport associated with non-zero Chern numbers has only been observed in electronic systems2, 4, 5. Here we use the transverse deflection of an atomic cloud in response to an optical gradient to measure the Chern number of artificially generated Hofstadter bands6. These topological bands are very flat and thus constitute good candidates for the realization of fractional Chern insulators7. Combining these deflection measurements with the determination of the band populations, we obtain an experimental value for the Chern number of the lowest band νexp = 0.99(5). This first Chern-number measurement in a non-electronic system is facilitated by an all-optical artificial gauge field scheme, generating uniform flux in optical superlattices.链接：http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys3171.html6.标题：Fractional excitations in the square-lattice quantum antiferromagnet 作者：B.

The quantum square-lattice Heisenberg antiferromagnet, for example, exhibits a striking anomaly of hitherto unknown origin in its magnetic excitation spectrum. This quantum effect manifests itself for excitations propagating with the specific wavevector (π, 0). We use polarized neutron spectroscopy to fully characterize the magnetic fluctuations in the metal-organic compound Cu(DCOO)2⋅4D2O, a known realization of the quantum square-lattice Heisenberg antiferromagnet model. Our experiments reveal an isotropic excitation continuum at the anomaly, which we analyse theoretically using Gutzwiller-projected trial wavefunctions. The excitation continuum is accounted for by the existence of spatially extended pairs of fractional S = 1/2 quasiparticles, 2D analogues of 1D spinons. Away from the anomalous wavevector, these fractional excitations are bound and form conventional magnons. Our results establish the existence of fractional quasiparticles in the high-energy spectrum of a quasi-two-dimensional antiferromagnet, even in the absence of frustration.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3172.html

Mikhail I. Katsnelson, Francesc Pérez-Murano & Julio Gómez-Herrero摘要： The extraordinary strength, stiffness1 and lightness of graphene have generated great expectations of its application in flexible electronics and as a mechanical reinforcement agent. However, the presence of lattice defects, unavoidable in sheets obtained by scalable routes, might degrade its mechanical properties2, 3. Here we report a systematic study on the elastic modulus and strength of graphene with a controlled density of defects. Counter-intuitively, the in-plane Young’s modulus increases with increasing defect density up to almost twice the initial value for a vacancy content of ~0.2%. For a higher density of vacancies, the elastic modulus decreases with defect inclusions. The initial increase in Young’s modulus is explained in terms of a dependence of the elastic coefficients on the momentum of flexural modes predicted for two-dimensional membranes4, 5. In contrast, the fracture strength decreases with defect density according to standard fracture continuum models. These quantitative structure–property relationships, measured in atmospheric conditions, are of fundamental and technological relevance and provide guidance for applications in which graphene mechanics represents a disruptive improvement.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3183.html#close

Otrokov, Evgueni V. Chulkov, Andrés Arnau, Amadeo L. Vázquez de Parga, Francisco Guinea & Rodolfo Miranda摘要：The electronic band structure of a material can acquire interesting topological properties in the presence of a magnetic field or as a result of the spin–orbit coupling1, 2, 3. We study graphene on Ir, with Pb monolayer islands intercalated between the graphene sheet and the Ir surface. Although the graphene layer is structurally unaffected by the presence of the Pb islands, its electronic properties change markedly, with regularly spaced resonances appearing. We interpret these resonances as the effect of a strong and spatially modulated spin–orbit coupling, induced in graphene by the Pb monolayer. As well as confined electronic states, the electronic spectrum has a series of gaps with non-trivial topological properties, resembling a realization of the quantum spin Hall effect proposed by Bernevig and Zhang4.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3173.html

Zelevinsky摘要：Weakly bound molecules have physical properties without atomic analogues, even as the bond length approaches dissociation. For instance, the internal symmetries of homonuclear diatomic molecules result in the formation of two-body superradiant and subradiant excited states. Whereas superradiance1, 2, 3 has been demonstrated in a variety of systems, subradiance4, 5, 6 is more elusive owing to the inherently weak interaction with the environment. Here we characterize the properties of deeply subradiant molecular states with intrinsic quality factors exceeding 1013 via precise optical spectroscopy with the longest molecule–light coherent interaction times to date. We find that two competing effects limit the lifetimes of the subradiant molecules, with different asymptotic behaviours. The first is radiative decay via weak magnetic-dipole and electric-quadrupole
67
interactions. We prove that its rate increases quadratically with the bond length, confirming quantum mechanical predictions. The second is non-radiative decay through weak gyroscopic predissociation, with a rate proportional to the vibrational mode spacing and sensitive to short-range physics. This work bridges the gap between atomic and molecular metrology based on lattice-clock techniques7, enhancing our understanding of long-range interatomic interactions.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3182.html
10.标题：Stiffening solids with liquid inclusions 作者：Robert W. Style, Rostislav Boltyanskiy, Benjamin Allen, Katharine E. Jensen, Henry P. Foote, John S. Wettlaufer & Eric R. Dufresne摘要：From bone and wood to concrete and carbon fibre, composites are ubiquitous natural and synthetic materials. Eshelby’s inclusion theory describes how macroscopic stress fields couple to isolated microscopic inclusions, allowing prediction of a composite’s bulk mechanical properties from a knowledge of its microstructure. It has been extended to describe a wide variety of phenomena from solid fracture to cell adhesion. Here, we show experimentally and theoretically that Eshelby’s theory breaks down for small liquid inclusions in a soft solid. In this limit, an isolated droplet’s deformation is strongly size-dependent, with the smallest droplets mimicking the behaviour of solid inclusions. Furthermore, in opposition to the predictions of conventional composite theory, we find that finite concentrations of small liquid inclusions enhance the stiffness of soft solids. A straightforward extension of Eshelby’s theory, accounting for the surface tension of the solid–liquid interface, explains our experimental observations. The counterintuitive stiffening of solids by fluid inclusions is expected whenever inclusion radii are smaller than an elastocapillary length, given by the ratio of the surface tension to Young’s modulus of the solid matrix. These results suggest that surface tension can be a simple and effective mechanism to cloak the far-field elastic signature of inclusions.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3181.html
11. 标题:Strong magneto-chiral dichroism in a paramagnetic molecular helix observed by hard X-rays 作者：Roberta Sessoli, Marie-Emmanuelle Boulon, Andrea Caneschi, Matteo Mannini, Lorenzo Poggini, Fabrice Wilhelm & Andrei Rogalev摘要： Magneto-chiral dichroism is a non-reciprocal—that is, directional—effect observed in magnetized chiral systems, featuring an unbalanced absorption of unpolarized light depending on the direction of the magnetization. Despite the fundamental interest in a phenomenon breaking both parity and time-reversal symmetries, magneto-chiral dichroism is one of the least investigated aspects of light–matter interaction most likely because of the weakness of the effect in most reported experiments. Here we have exploited the element selectivity of hard X-ray radiation to investigate the magneto-chiral properties of enantiopure crystals of two isostructural molecular helicoidal chains comprising either cobalt(II) or manganese(II) ions. A strong magneto-chiral dichroism, with Kuhn asymmetry of the order of a few per cent, has been observed in the cobalt chains system, whereas it is practically absent for the manganese derivative. The spectral features of the X-ray magneto-chiral dichroism signal differ significantly from the natural and magnetic dichroic contributions and have been rationalized here using the multipolar expansion of matter–radiation interaction.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3152.html

Shibauchi & Y. Matsuda摘要：The superconducting fluctuation effect, due to preformed Cooper pairs above the critical temperature Tc, has been generally understood by the standard Gaussian fluctuation theories in most superconductors1. The transverse thermoelectric (Nernst) effect is particularly sensitive to the fluctuations, and the large Nernst signal found in the pseudogap regime of the underdoped cuprates2, 3 has raised much debate. Here we report on the observation of a colossal Nernst signal due to the superconducting fluctuations in the heavy-fermion superconductor URu2Si2. The Nernst coefficient is anomalously enhanced (by a factor of ~106) as compared with the theoretically expected value of the Gaussian fluctuations. Moreover, contrary to the conventional wisdom, the enhancement is more significant with a reduction of the impurity scattering rate. This unconventional Nernst effect intimately reflects the highly unusual superconducting state of URu2Si2. The results invoke possible chiral or Berry-phase fluctuations associated with the broken time-reversal symmetry4, 5, 6, 7 of the superconducting order parameter.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3170.html

In graphene, however, owing to its non-harmonic spectrum, individual levels can be addressed selectively. Here, we report a time-resolved experiment directly pumping discrete Landau levels in graphene. Energetically degenerate Landau-level transitions from n = −1 to n = 0
69
and from n = 0 to n = 1 are distinguished by applying circularly polarized THz light. An analysis based on a microscopic theory shows that the zeroth Landau level is actually depleted by strong Auger scattering, even though it is optically pumped at the same time. The surprisingly strong electron–electron interaction responsible for this effect is directly evidenced through a sign reversal of the pump–probe signal.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3164.html

Zurek, Cristian D. Batista & Sang-Wook Cheong摘要：Lars Onsager and Richard Feynman envisaged that the three-dimensional (3D) superfluid-to-normal λ transition in 4He occurs through the proliferation of vortices. This process should hold for every phase transition in the same universality class. The role of topological defects in symmetry-breaking phase transitions has become a prime topic in cosmology and high-temperature superconductivity, even though direct imaging of these defects is challenging. Here we show that the U(1) continuous symmetry that emerges at the ferroelectric critical point of multiferroic hexagonal manganites leads to a similar proliferation of vortices. Moreover, the disorder field (vortices) is coupled to an emergent U(1) gauge field, which becomes massive by means of the Higgs mechanism when vortices condense (span the whole system) on heating above the ferroelectric transition temperature. Direct imaging of the vortex network in hexagonal manganites offers unique experimental access to this dual description of the ferroelectric transition, while enabling tests of the Kibble–Zurek mechanism.链接：http://www.nature.com/nphys/journal/v10/n12/full/nphys3142.html
17.标题： Hunting for topological dark matter with atomic clocks 作者：A. Derevianko & M. Pospelov摘要：The cosmological applications of atomic clocks1, 2, 3 so far have been limited to searches for the uniform-in-time drift of fundamental constants4. We point out that a transient-in-time change of fundamental constants can be induced by dark-matter objects that have large spatial extent, such as stable topological defects5 built from light non-Standard Model fields. Networks of correlated atomic clocks, some of them already in existence6, such as the Global Positioning System, can be used as a powerful tool to search for topological defect dark matter, thus providing another important fundamental physics application for the ever-improving accuracy of atomic clocks. During the encounter with an extended dark-matter object, as it sweeps through the network, initially synchronized clocks will become desynchronized. Time discrepancies between spatially separated clocks are expected to exhibit a distinct signature, encoding the defect’s space structure and its interaction strength with atoms.链接：http://www.nature.com/nphys/journal/v10/n12/full/nphys3137.html

70
quantum computation and simulation1, 2 to enhanced metrology3 and secure communication1. These applications require the quantum control of large networks of qubits to realize gains and speed increases over conventional devices. However, propagating entanglement becomes difficult or impossible as the system grows in size. Here, we demonstrate the first step in a modular approach4 to scaling entanglement by using complementary quantum buses on a collection of three atomic ion qubits stored in two remote ion trap modules. Entanglement within a module is achieved with deterministic near-field interactions through phonons5, and remote entanglement between modules is achieved with a probabilistic interaction through photons6. This minimal system allows us to address generic issues in the synchronization of entanglement with multiple buses. It points the way towards a modular large-scale quantum information architecture that promises less spectral crowding and thus potentially less decoherence as the number of qubits increases4. We generate this modular entanglement faster than the observed remotely entangled qubit-decoherence rate, showing that entanglement can be scaled simply by adding more modules.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3150.html
19.标题：Wettability-independent bouncing on flat surfaces mediated by thin air films 作者：Jolet de Ruiter, Rudy Lagraauw, Dirk van den Ende & Frieder Mugele摘要： The impingement of drops onto solid surfaces1, 2 plays a crucial role in a variety of processes, including inkjet printing, fog harvesting, anti-icing, dropwise condensation and spray coating3, 4, 5, 6. Recent efforts in understanding and controlling drop impact behaviour focused on superhydrophobic surfaces with specific surface structures enabling drop bouncing with reduced contact time7, 8. Here, we report a different universal bouncing mechanism that occurs on both wetting and non-wetting flat surfaces for both high and low surface tension liquids. Using high-speed multiple-wavelength interferometry9, we show that this bouncing mechanism is based on the continuous presence of an air film for moderate drop impact velocities. This submicrometre ‘air cushion’ slows down the incoming drop and reverses its momentum. Viscous forces in the air film play a key role in this process: they provide transient stability of the air cushion against squeeze-out, mediate momentum transfer, and contribute a substantial part of the energy dissipation during bouncing.链接：http://www.nature.com/nphys/journal/v11/n1/full/nphys3145.html

J. Bending, F. M. Peeters & W. K. Kwok摘要： Depending on the Ginzburg–Landau parameter κ, superconductors can either be fully diamagnetic if (type I superconductors) or allow magnetic flux to penetrate through Abrikosov vortices if (type II superconductors; refs 1, 2). At the Bogomolny critical point, , a state that is infinitely degenerate with respect to vortex spatial configurations arises3, 4. Despite in-depth investigations of conventional type I and type II superconductors, a thorough understanding of the magnetic behaviour in the near-Bogomolny critical regime at κ ∼ κc remains lacking. Here we report that in confined systems the critical regime expands over a finite interval of κ forming a critical superconducting state. We show that in this state, in a sample with dimensions comparable to the vortex core size, vortices merge into a multi-quanta droplet, which undergoes Rayleigh instability5 on increasing κ and decays by emitting single vortices. Superconducting vortices realize Nielsen–

Zahid Hasan & Yong P. Chen摘要：A three-dimensional (3D) topological insulator (TI) is a quantum state of matter with a gapped insulating bulk yet a conducting surface hosting topologically protected gapless surface states. One of the most distinct electronic transport signatures predicted for such topological surface states (TSS) is a well-defined half-integer quantum Hall effect (QHE) in a magnetic field, where the surface Hall conductivities become quantized in units of (1/2)e2/h (e being the electron charge, h the Planck constant) concomitant with vanishing resistance. Here, we observe a well-developed QHE arising from TSS in an intrinsic TI of BiSbTeSe2. Our samples exhibit surface-dominated conduction even close to room temperature, whereas the bulk conduction is negligible. At low temperatures and high magnetic fields perpendicular to the top and bottom surfaces, we observe well-developed integer quantized Hall plateaux, where the two parallel surfaces each contribute a half-integer e2/h quantized Hall conductance, accompanied by vanishing longitudinal resistance. When the bottom surface is gated to match the top surface in carrier density, only odd integer QH plateaux are observed, representing a half-integer QHE of two degenerate Dirac gases. This system provides an excellent platform to pursue a plethora of exotic physics and novel device applications predicted for TIs, ranging from magnetic monopoles and Majorana particles to dissipationless electronics and fault-tolerant quantum computers.链接：http://www.nature.com/nphys/journal/v10/n12/full/nphys3140.html
22.标题：Magnetic-free non-reciprocity and isolation based on parametrically modulated coupled-resonator loops 作者：Nicholas A. Estep, Dimitrios L. Sounas, Jason Soric & Andrea Alù摘要: Non-reciprocal components, which are essential to many modern communication systems, are almost exclusively based on magneto-optical materials, severely limiting their applicability. A practical and inexpensive route to magnetic-free non-reciprocity could revolutionize radio-frequency and nanophotonic communication networks. Angular-momentum biasing was recently proposed as a means of realizing isolation for sound waves travelling in a rotating medium1, and envisaged as a path towards compact, linear integrated non-reciprocal electromagnetic components2, 3. Inspired by this concept, here we demonstrate a subwavelength, linear radio-frequency non-reciprocal circulator free from magnetic materials and bias. The scheme is based on the parametric modulation of three identical, strongly and symmetrically coupled resonators. Their resonant frequencies are modulated by external signals with the same amplitude and a relative phase difference of 120°, imparting an effective electronic angular momentum to the system. We observe giant non-reciprocity, with up to six orders of magnitude difference in transmission for opposite directions. Furthermore, the device topology is tunable in real time, and can be directly embedded in a conventional integrated circuit.

Gilbert, Fangcheng Chou, Nitin Samarth & M. Zahid Hasan摘要： Superconductivity involving topological Dirac electrons has recently been proposed as a platform between concepts in high-energy and condensed-matter physics. It has been predicted that supersymmetry and Majorana fermions, both of which remain elusive in particle physics, may be realized through emergent particles in these particular superconducting systems. Using artificially fabricated topological-insulator–superconductor heterostructures, we present direct spectroscopic evidence for the existence of Cooper pairing in a weakly interacting half Dirac gas. Our studies reveal that two dimensional topological superconductivity in a helical Dirac gas is distinctly different from that in an ordinary two-dimensional superconductor in terms of the spin degrees of freedom of electrons. We further show that the pairing of Dirac electrons can be suppressed by time-reversal symmetry-breaking impurities, thereby removing the distinction. Our demonstration and momentum-space imaging of Cooper pairing in a half-Dirac-gas two-dimensional topological superconductor serve as a critically important platform for future testing of fundamental physics predictions such as emergent supersymmetry and topological quantum criticality.链接：http://www.nature.com/nphys/journal/v10/n12/full/nphys3139.html
24.标题：Collisions of matter-wave solitons 作者：Jason H. V. Nguyen, Paul Dyke, De Luo, Boris A. Malomed & Randall G. HuletShow fewer authors摘要：Solitons are localized wave disturbances that propagate without changing shape, a result of a nonlinear interaction that compensates for wave packet dispersion. Individual solitons may collide, but a defining feature is that they pass through one another and emerge from the collision unaltered in shape, amplitude, or velocity, but with a new trajectory reflecting a discontinuous jump. This remarkable property is mathematically a consequence of the underlying integrability of the one-dimensional (1D) equations, such as the nonlinear Schrödinger equation, that describe solitons in a variety of wave contexts, including matter waves1, 2. Here we explore the nature of soliton collisions using Bose–Einstein condensates of atoms with attractive interactions confined to a quasi-1D waveguide. Using real-time imaging, we show that a collision between solitons is a complex event that differs markedly depending on the relative phase between the solitons. By controlling the strength of the nonlinearity we shed light on these fundamental features of soliton collisional dynamics, and explore the implications of collisions in the proximity of the crossover between one and three dimensions where the loss of integrability may precipitate catastrophic collapse.链接：http://www.nature.com/nphys/journal/v10/n12/full/nphys3135.html

73
摘要：Topological crystalline insulators in IV–VI compounds host novel topological surface states consisting of multi-valley massless Dirac fermions at low energy. Here we show that strain generically acts as an effective gauge field on these Dirac fermions and creates pseudo-Landau orbitals without breaking time-reversal symmetry. We predict the realization of this phenomenon in IV–VI semiconductor heterostructures, due to a naturally occurring misfit dislocation array at the interface that produces a periodically varying strain field. Remarkably, the zero-energy Landau orbitals form a flat band in the vicinity of the Dirac point, and coexist with a network of snake states at higher energy. We propose that the high density of states of this flat band gives rise to interface superconductivity observed in IV–VI semiconductor multilayers at unusually high temperatures, with non-Bardeen–Cooper–Schrieffer behaviour. Our work demonstrates a new route to altering macroscopic electronic properties to achieve a partially flat band, and provides a starting point for realizing novel correlated states of matter.链接：http://www.nature.com/nphys/journal/v10/n12/full/nphys3109.html
