A Variational Approach to Nonsmooth Dynamics
by Samir AdlyThis brief examines mathematical models in nonsmooth mechanics and nonregular electrical circuits, including evolution variational inequalities, complementarity systems, differential inclusions, second-order dynamics, Lur'e systems and Moreau's sweeping process. The field of nonsmooth dynamics is of great interest to mathematicians, mechanicians, automatic controllers and engineers. The present volume acknowledges this transversality and provides a multidisciplinary view as it outlines fundamental results in nonsmooth dynamics and explains how to use them to study various problems in engineering. In particular, the author explores the question of how to redefine the notion of dynamical systems in light of modern variational and nonsmooth analysis. With the aim of bridging between the communities of applied mathematicians, engineers and researchers in control theory and nonlinear systems, this brief outlines both relevant mathematical proofs and models in unilateral mechanics and electronics.
Variational Methods for Machine Learning with Applications to Deep Networks
by Lucas Pinheiro Cinelli Matheus Araújo Marins Eduardo Antônio Barros da Silva Sérgio Lima NettoThis book provides a straightforward look at the concepts, algorithms and advantages of Bayesian Deep Learning and Deep Generative Models. Starting from the model-based approach to Machine Learning, the authors motivate Probabilistic Graphical Models and show how Bayesian inference naturally lends itself to this framework. The authors present detailed explanations of the main modern algorithms on variational approximations for Bayesian inference in neural networks. Each algorithm of this selected set develops a distinct aspect of the theory. The book builds from the ground-up well-known deep generative models, such as Variational Autoencoder and subsequent theoretical developments. By also exposing the main issues of the algorithms together with different methods to mitigate such issues, the book supplies the necessary knowledge on generative models for the reader to handle a wide range of data types: sequential or not, continuous or not, labelled or not. The book is self-contained, promptly covering all necessary theory so that the reader does not have to search for additional information elsewhere. Offers a concise self-contained resource, covering the basic concepts to the algorithms for Bayesian Deep Learning;Presents Statistical Inference concepts, offering a set of elucidative examples, practical aspects, and pseudo-codes;Every chapter includes hands-on examples and exercises and a website features lecture slides, additional examples, and other support material.

Variational Methods with Applications in Science and Engineering
by Kevin W. CasselThere is a resurgence of applications in which the calculus of variations has direct relevance. In addition to application to solid mechanics and dynamics, it is now being applied in a variety of numerical methods, numerical grid generation, modern physics, various optimization settings and fluid dynamics. Many applications, such as nonlinear optimal control theory applied to continuous systems, have only recently become tractable computationally, with the advent of advanced algorithms and large computer systems. This book reflects the strong connection between calculus of variations and the applications for which variational methods form the fundamental foundation. The mathematical fundamentals of calculus of variations (at least those necessary to pursue applications) is rather compact and is contained in a single chapter of the book. The majority of the text consists of applications of variational calculus for a variety of fields.
Variations on Media Thinking (Posthumanities #52)
by Siegfried ZielinskiA diverse, enriching volume of media analysis from a pioneering thinker in the field Expanding on Siegfried Zielinski&’s groundbreaking inquiry into &“deep time&” of the media, the essays in Variations on Media Thinking further the eminent media theorist&’s unique method of expanded hermeneutics, which means for him interpreting technical artifacts as essential parts of our cultural lives. Covering such topics as the televisualized &“Holocaust,&” the ubiquity of media today, the Internet, the genealogy of sound art, and history&’s first hacker movement, these essays further diversify Zielinski&’s insight into the hidden layers of media development, which he first articulated in his pioneering work Deep Time of the Media.Including many previously untranslated and scarce essays, these &“written time machines&” open new lines of investigation for cultural scholars. From the automata of the Arabic-Islamic Renaissance (800–1200) to the largest and loudest techno-event ever, known as The Symphony of Sirens—which transformed Baku in 1922 into an immense music box of modern noise—Variations on Media Thinking covers Zielinski&’s inquiries since 1975. Richly illustrated and full of provocation, brilliant insight, and fascinating research, this volume is perfect for students of media archaeology, philosophy, and technology, as well as any adventurous, rigorous thinkers engaged with culture and media.
Varicella-zoster Virus: Genetics, Pathogenesis and Immunity (Current Topics in Microbiology and Immunology #438)
by Ann M. Arvin Jennifer F. Moffat Allison Abendroth Stefan L OliverThis edited volume provides insights about the molecular virology, pathoenesis of infection and host responses to varicella-zoster virus, which is a medically important human herpesvirus. The chapters not only discuss genetics and molecular evolution of the virus, but also new structure-based knowledge on the functions of viral glycoproteins. Further, the authors illustrate how mechanisms from the virus are used to take over and remodel host cells during pathogeneis. These mechanisms also enable viral modulation of host cells and evasion of the host immune response. Part of these evasion and survival strategies, is the reaction to triggered host cell responses like autophagy, the stress response, modulation of apoptosis and other cell death pathways. This hands-on knowledge is crucial for students and clinicians in Virology, Immunology, and Infectious Diseases.Chapter "Common features between stroke following varicella in children and stroke following herpes zoster in adults" is available open access under a Creative Commons Attribution 4.0 International License via Springerlink.com.
Varying Gravity
by Helge KraghThe main focus of this book is on the interconnection of two unorthodox scientific ideas, the varying-gravity hypothesis and the expanding-earth hypothesis. As such, it provides a fascinating insight into a nearly forgotten chapter in both the history of cosmology and the history of the earth sciences. The hypothesis that the force of gravity decreases over cosmic time was first proposed by Paul Dirac in 1937. In this book the author examines in detail the historical development of Dirac's hypothesis and its consequences for the structure and history of the earth, the most important of which was that the earth must have been smaller in the past.

The Vascular Flora of the Bosco della Mesola Nature Reserve (Geobotany Studies)
by Alessandro Alessandrini Giampaolo Balboni Lisa Brancaleoni Renato Gerdol Giovanni Nobili Mauro Pellizzari Filippo Piccoli Michele RavaglioliThe Bosco della Mesola represents one of the few remnants of coastal woodlands in Italy. A nature reserve was established in this area in 1977. No detailed checklists of the vascular flora of the nature reserve have been compiled since then. So, there was an urgent need to fill this gap. This book contains a critical updated checklist of the vascular flora in the Bosco della Mesola Nature Reserve. It also allows quantitative comparisons with a previous checklist dating back to the 1960s in order to detect temporal changes in the vascular flora over 60 years. We believe that this book represents a milestone for scientists and all people involved in nature conservation and management in this area and in similar territories in other countries. The readerships can also include high-school students and non-professional botany amateurs.

Vasculopathies: Behavioral, Chemical, Environmental, and Genetic Factors (Biomathematical and Biomechanical Modeling of the Circulatory and Ventilatory Systems #8)
by Marc ThirietThis volume presents one of the clinical foundations of vasculopathies: the biological markers and risk factors associated with cardiovascular disease. A detailed biological and clinical framework is provided as a prerequisite for adequate modeling. Chapter 1 presents cardiovascular risk factors and markers, where the search for new criteria is aimed at improving early detection of chronic diseases. The subsequent chapters focus on hypertension, which involves the kidney among other organs as well as many agents, hyperglycemia and diabetes, hyperlipidemias and obesity, and behavior. The last of these risk factors includes altered circadian rhythm, tobacco and alcohol consumption, physical inactivity, and diet. The volumes in this series present all of the data needed at various length scales for a multidisciplinary approach to modeling and simulation of flows in the cardiovascular and ventilatory systems, especially multiscale modeling and coupled simulations. The cardiovascular and respiratory systems are tightly coupled, as their primary function is to supply oxygen to and remove carbon dioxide from the body's cells. Because physiological conduits have deformable and reactive walls, macroscopic flow behavior and prediction must be coupled to nano- and microscopic events in a corrector scheme of regulated mechanisms. Therefore, investigation of flows of blood and air in anatomical conduits requires an understanding of the biology, chemistry, and physics of these systems together with the mathematical tools to describe their functioning in quantitative terms.

A Vast Machine: Computer Models, Climate Data, and the Politics of Global Warming (Infrastructures)
by Paul N. EdwardsThe science behind global warming, and its history: how scientists learned to understand the atmosphere, to measure it, to trace its past, and to model its future.Global warming skeptics often fall back on the argument that the scientific case for global warming is all model predictions, nothing but simulation; they warn us that we need to wait for real data, “sound science.” In A Vast Machine Paul Edwards has news for these skeptics: without models, there are no data. Today, no collection of signals or observations—even from satellites, which can “see” the whole planet with a single instrument—becomes global in time and space without passing through a series of data models. Everything we know about the world's climate we know through models. Edwards offers an engaging and innovative history of how scientists learned to understand the atmosphere—to measure it, trace its past, and model its future.
