The Collectin Protein Family and Its Multiple Biological Activities

by Uday Kishore Taruna Madan Robert B. Sim

The topic of this book, Collectins, is a family of proteins whose major function is in innate immunity, where Collectins act as pattern recognition receptors (PRRs). In general they recognize targets such as microbial surfaces and apoptotic cells, and once bound to a target, Collectins promote the clearance of microorganisms and damaged host tissue. New cell-surface proteins and glycoproteins, which act as Collectin receptors, are currently being identified. Some Collectins, particularly MBL, activate the complement system, which enhances the ability of antibodies to fight pathogens, via three MBL-associated proteases, the MASPs. Additionally, recent research has begun to show wider-ranging activities of Collectins, such as: · Their role in metabolism, and therefore their involvement in lifestyle diseases such as obesity and cardiovascular disease.· Their ability to modulate the adaptive immune response, as well as to recognize and trigger apoptosis of cancer cells, which makes them effective in the annihilation of cancer cells with multiple mutations.· The regulation of their expression by gonadal steroid hormones implicates them with critical roles in both male and female fertility.· Altered levels of Collectins have been associated with various autoimmune diseases.This book brings together current knowledge of the structure, functions and biological activities of Collectins, to describe their integral role in human health.

Collecting Experiments: Making Big Data Biology

by Bruno J. Strasser

Databases have revolutionized nearly every aspect of our lives. Information of all sorts is being collected on a massive scale, from Google to Facebook and well beyond. But as the amount of information in databases explodes, we are forced to reassess our ideas about what knowledge is, how it is produced, to whom it belongs, and who can be credited for producing it. Every scientist working today draws on databases to produce scientific knowledge. Databases have become more common than microscopes, voltmeters, and test tubes, and the increasing amount of data has led to major changes in research practices and profound reflections on the proper professional roles of data producers, collectors, curators, and analysts. Collecting Experiments traces the development and use of data collections, especially in the experimental life sciences, from the early twentieth century to the present. It shows that the current revolution is best understood as the coming together of two older ways of knowing—collecting and experimenting, the museum and the laboratory. Ultimately, Bruno J. Strasser argues that by serving as knowledge repositories, as well as indispensable tools for producing new knowledge, these databases function as digital museums for the twenty-first century.

Collective Action and Exchange: A Game-Theoretic Approach to Contemporary Political Economy

by William D. Ferguson

In Collective Action and Exchange: A Game-Theoretic Approach to Contemporary Political Economy, William D. Ferguson presents a comprehensive political economy text aimed at advanced undergraduates in economics and graduate students in the social sciences. The text utilizes collective action as a unifying concept, arguing that collective-action problems lie at the foundation of market success, market failure, economic development, and the motivations for policy. Ferguson draws on information economics, social preference theory, cognition theory, institutional economics, as well as political and policy theory to develop this approach. The text uses classical, evolutionary, and epistemic game theory, along with basic social network analysis, as modeling frameworks. These models effectively bind the ideas presented, generating a coherent theoretic approach to political economy that stresses sometimes overlooked implications.

Collective Animal Behavior

by David J. Sumpter

How and why animals produce group behaviorsFish travel in schools, birds migrate in flocks, honeybees swarm, and ants build trails. How and why do these collective behaviors occur? Exploring how coordinated group patterns emerge from individual interactions, Collective Animal Behavior reveals why animals produce group behaviors and examines their evolution across a range of species.Providing a synthesis of mathematical modeling, theoretical biology, and experimental work, David Sumpter investigates how animals move and arrive together, how they transfer information, how they make decisions and synchronize their activities, and how they build collective structures. Sumpter constructs a unified appreciation of how different group-living species coordinate their behaviors and why natural selection has produced these groups. For the first time, the book combines traditional approaches to behavioral ecology with ideas about self-organization and complex systems from physics and mathematics. Sumpter offers a guide for working with key models in this area along with case studies of their application, and he shows how ideas about animal behavior can be applied to understanding human social behavior.Containing a wealth of accessible examples as well as qualitative and quantitative features, Collective Animal Behavior will interest behavioral ecologists and all scientists studying complex systems.

Collective Atom-Light Interactions in Dense Atomic Vapours (Springer Theses)

by James Keaveney

The propagation of light in 'dense media' where dipole-dipole interactions play a role is a fundamental topic that was first studied in the work of Clausius, Mossotti, Lorenz and Lorentz in the latter half of the nineteenth century. However, until recently there remained some areas of controversy: for example, whereas the Lorentz model for a gas predicts a resonance shift, a discrete dipole model does not. This thesis makes the first combined measurement of both the Lorentz shift and the associated collective Lamb shift. This clear experimental result stimulated new theoretical work that has significantly advanced our understanding of light propagation in interacting media.

Collective Behavior: Interdisciplinary Research Team Summaries

by The National Academies Keck Futures Initiative

"Collective Behavior" is the summary of the 2014 National Academies Keck Futures Initiative Conference on Collective Behavior. Participants were divided into fourteen interdisciplinary research teams. The teams spent nine hours over two days exploring diverse challenges at the interface of science, engineering, and medicine. The composition of the teams was intentionally diverse, to encourage the generation of new approaches by combining a range of different types of contributions. The teams included researchers from science, engineering, and medicine, as well as representatives from private and public funding agencies, universities, businesses, journals, and the science media. Researchers represented a wide range of experience - from postdoc to those well established in their careers - from a variety of disciplines that included science and engineering, medicine, physics, biology, economics, and behavioral science. The teams needed to address the challenge of communicating and working together from a diversity of expertise and perspectives as they attempted to solve a complicated, interdisciplinary problem in a relatively short time. This report highlights the presentations of the event and includes the team reports and pre-meeting materials.

Collective Behavior in Complex Networked Systems under Imperfect Communication

by Jianquan Lu Lulu Li Daniel W.C. Ho Jinde Cao

This book aims to explain how collective behavior is formed via local interactions under imperfect communication in complex networked systems. It also presents some new distributed protocols or algorithms for complex networked systems to comply with bandwidth limitation and tolerate communication delays. This book will be of particular interest to the readers due to the benefits: 1) it studies the effect of time delay and quantization on the collective behavior by non-smooth analytical technique and algebraic graph theory; 2) it introduces the event-based consensus method under delayed information transmission; In the meantime, it presents some novel approaches to handle the communication constraints in networked systems; 3) it gives some synchronization and control strategies for complex networked systems with limited communication abilities. Furthermore, it provides a consensus recovery approach for multi-agent systems with node failure. Also, it presents interesting results about bipartite consensus and fixed-time/finite-time bipartite consensus of networks with cooperative and antagonistic interactions.

Collective Behavior of Magnetic Micro/Nanorobots: Control, Imaging, and Applications

by Qianqian Wang Jiangfan Yu

Collective Behavior of Magnetic Micro/Nanorobots: Control, Imaging, and Applications reviews recent advances in the design and construction of magnetic collective micro/nanorobot systems, and promotes the bridging of the gap between their theoretical investigation and practical applications. By summarizing the recent progress in control, imaging, and biomedical applications of collective micro/nanorobots, the authors show the big picture of micro/nanorobotics and the roadmap of collective micro/nanorobots. They then discuss the control, imaging, and biomedical applications of collective micro/nanorobots, respectively, demonstrating the state-of-the-art techniques and ideas for designing systems of collective micro/nanorobots that can help researchers have a better understanding and further stimulate the development of such an exciting field. This book is suitable for scientists, engineers, and students involved in the study of robotics, control, materials, and mechanical/electrical engineering.

Collective Dynamics of Particles: From Viscous to Turbulent Flows (CISM International Centre for Mechanical Sciences #576)

by Cristian Marchioli

The book surveys the state-of-the-art methods that are currently available to model and simulate the presence of rigid particles in a fluid flow. For particles that are very small relative to the characteristic flow scales and move without interaction with other particles, effective equations of motion for particle tracking are formulated and applied (e.g. in gas-solid flows). For larger particles, for particles in liquid-solid flows and for particles that interact with each other or possibly modify the overall flow detailed model are presented. Special attention is given to the description of the approximate force coupling method (FCM) as a more general treatment for small particles, and derivations in the context of low Reynolds numbers for the particle motion as well as application at finite Reynolds numbers are provided. Other topics discussed in the book are the relation to higher resolution immersed boundary methods, possible extensions to non-spherical particles and examples of applications of such methods to dispersed multiphase flows.

Collective Excitations in the Antisymmetric Channel of Raman Spectroscopy (Springer Theses)

by Hsiang-Hsi Kung

This thesis contains three breakthrough results in condensed matter physics. Firstly, broken reflection symmetry in the hidden-order phase of the heavy-fermion material URu2Si2 is observed for the first time. This represents a significant advance in the understanding of this enigmatic material which has long intrigued the condensed matter community due to its emergent long range order exhibited at low temperatures (the so-called “hidden order”). Secondly and thirdly, a novel collective mode (the chiral spin wave) and a novel composite particle (the chiral exciton) are discovered in the three dimensional topological insulator Bi2Se3. This opens up new avenues of possibility for the use of topological insulators in photonic, optoelectronic, and spintronic devices. These discoveries are facilitated by using low-temperature polarized Raman spectroscopy as a tool for identifying optically excited collective modes in strongly correlated electron systems and three-dimensional topological insulators.

Collective Phenomena in Plasmas and Elsewhere: Kinetic and Hydrodynamic Approaches

by Kamel Ourabah

The Universe is made up of systems consisting of a very large number of particles interacting in a very complex way. When studying these systems, a precise microscopic approach is unattainable. In practice, the best strategy is one that is able to “distinguish” between superfluous information and the information needed to make predictions about the evolution of the system. There are two main competing approaches: kinetic and hydrodynamic. Collective Phenomena in Plasmas and Elsewhere presents an overview of the theoretical bases of these kinetic and hydrodynamic approaches, but also discusses their limitations, the links between them and their extension to quantum mechanics and relativity. These methods were born in part out of the study of plasmas, but they also have more universal applications. A general framework for these approaches is outlined, followed by some applications in plasmas, gravitation, Bose–Einstein condensates and dark matter. Particular emphasis is placed on the analogies that can be made between all these different systems.

Collective Plasmon-Modes in Gain Media: Quantum Emitters and Plasmonic Nanostructures (SpringerBriefs in Physics)

by V. A. G. Rivera O. B. Silva Y. Ledemi Y. Messaddeq E. Marega

This book represents the first detailed description, including both theoretical aspects and experimental methods, of the interaction of rare-earth ions with surface plasmon polariton from the point of view of collective plasmon-photon interactions via resonance modes (metal nanoparticles or nanostructure arrays) with quantum emitters (rare-earth ions). These interactions are of particular interest for applications to optical telecommunications, optical displays, and laser solid state technologies. Thus, our main goal is to give a more precise overview of the rapidly emerging field of nanophotonics by means of the study of the quantum properties of light interaction with matter at the nanoscale. In this way, collective plasmon-modes in a gain medium result from the interaction/coupling between a quantum emitter (created by rare-earth ions) with a metallic surface, inducing different effects such as the polarization of the metal electrons (so-called surface plasmon polariton - SPP), a field enhancement sustained by resonance coupling, or transfer of energy due to non-resonant coupling between the metallic nanostructure and the optically active surrounding medium. These effects counteract the absorption losses in the metal to enhance luminescence properties or even to control the polarization and phase of quantum emitters. The engineering of plasmons/SPP in gain media constitutes a new field in nanophotonics science with a tremendous technological potential in integrated optics/photonics at the nanoscale based on the control of quantum effects. This book will be an essential tool for scientists, engineers, and graduate and undergraduate students interested not only in a new frontier of fundamental physics, but also in the realization of nanophotonic devices for optical telecommunication.

Collector's Guide to Fort Payne Crinoids and Blastoids (Life of the Past)

by William Morgan

Collector's Guide to Fort Payne Crinoids and Blastoids is the first comprehensive guide for identifying the fossils of echinoderms from hundreds of millions of years ago, when North America was covered by a warm, equatorial sea.Crinoids and blastoids, echinoderms (the same family of marine animals to include starfish, sea urchins, and sand dollars) from the Fort Payne Formation in Kentucky, are rarely seen at gem, mineral, and fossil shows, nor are they regularly displayed at major museums. By combining high-quality color photographs and an accompanying descriptive text, William W. Morgan provides the first comprehensive identification guide to these fascinating fossils. Collector's Guide to Fort Payne Crinoids and Blastoids features photographs, often offering more than one view, of the best-quality specimens curated in the Smithsonian and other prominent invertebrate fossil museums. Morgan includes photographs that are unlabeled so that readers can test themselves to see whether they can differentiate some of the more subtle features that may be necessary for accurate identification.

The Collectors of Lost Souls: Turning Kuru Scientists into Whitemen

by Warwick Anderson

This riveting account of medical detective work traces the story of kuru, a fatal brain disease, and the pioneering scientists who spent decades searching for its cause and cure.Winner, William H. Welch Medal, American Association for the History of MedicineWinner, Ludwik Fleck Prize, Society for Social Studies of ScienceWinner, General History Award, New South Wales Premier's History AwardsWhen whites first encountered the Fore people in the isolated highlands of colonial New Guinea during the 1940s and 1950s, they found a people in the grip of a bizarre epidemic. Women and children succumbed to muscle weakness, uncontrollable tremors, and lack of coordination, until death inevitably supervened. Facing extinction, the Fore attributed their unique and terrifying affliction to a particularly malign form of sorcery.In The Collectors of Lost Souls, Warwick Anderson tells the story of the resilience of the Fore through this devastating plague, their transformation into modern people, and their compelling attraction for a throng of eccentric and adventurous scientists and anthropologists. Battling competing scientists and the colonial authorities, the brilliant and troubled American doctor D. Carleton Gajdusek determined that the cause of the epidemic—kuru—was a new and mysterious agent of infection, which he called a slow virus (now called a prion). Anthropologists and epidemiologists soon realized that the Fore practice of eating their loved ones after death had spread the slow virus. Though the Fore were never convinced, Gajdusek received the Nobel Prize for his discovery. Now revised and updated, the book includes an extensive new afterword that situates its impact within the fields of science and technology studies and the history of science. Additionally, the author now reflects on his long engagement with the scientists and the people afflicted, describing what has happened to them since the end of kuru. This astonishing story links first-contact encounters in New Guinea with laboratory experiments in Bethesda, Maryland; sorcery with science; cannibalism with compassion; and slow viruses with infectious proteins, reshaping our understanding of what it means to do science.
