Ridge functions are a rich class of simple multivariate functions which have found applications in a variety of areas. These include partial differential equations (where they are sometimes termed 'plane waves'), computerised tomography, projection pursuit in the analysis of large multivariate data sets, the MLP model in neural networks, Waring's problem over linear forms, and approximation theory. Ridge Functions is the first book devoted to studying them as entities in and of themselves. The author describes their central properties and provides a solid theoretical foundation for researchers working in areas such as approximation or data science. He also includes an extensive bibliography and discusses some of the unresolved questions that may set the course for future research in the field.
This monograph discusses the qualitative linear theory of best L^T1-approximation from finite-dimensional subspaces. It presents a survey of recent research that extends "classical" results concerned with best-uniform approximation to the more general case. The work is organized to serve as a self-study guide or as a text for advanced courses. It begins with a basic introduction to the concepts of approximation theory before addressing 1- or 2-sided best approximations from finite-dimensional subspaces and approaches to the computation of these. At the end of each chapter is a series of exercises that give the reader an opportunity to test understanding and also contain some theoretical digressions and extensions of the text.
Bringing the word sustainability back from the brink of cliché—to a substantive, truly sustainable future Is sustainability a hopelessly vague word, with meager purpose aside from a feel-good appeal to the consumer? In The Three Sustainabilities, Allan Stoekl seeks to (re)valorize the word, for a simple reason: it is useful. Sustainability designates objects in time, their birth or genesis, their consistency, their survival, their demise. And it raises the question, as no other word does, of the role of humans in the survival of a world that is quickly disappearing—and perhaps in the genesis of another world. Stoekl considers a range of possibilities for the word, touching upon questions of object ontology, psychoanalysis, urban critique, technocracy, and religion. He argues that there are three varieties of sustainability, seen from philosophical, cultural, and economic perspectives. One involves the self-sustaining world “without us”; another, the world under our control, which can run the political spectrum from corporatism to Marxism to the Green New Deal; and a third that carries a social and communitarian charge, an energy of the “universe” affirmed through, among other things, meditation and gifting. Each of these carves out a different space in the relations between objects, humans, and their survival and degradation. Each is necessary, unavoidable, and intimately bound with, and infinitely distant from, the others. Along the way, Stoekl cites a wide range of authors, from philosophers to social thinkers, literary theorists to criminologists, anthropologists to novelists. This beautifully written, compelling, and nuanced book is a must for anyone interested in questions of ecology, energy, the environmental humanities, contemporary theories of the object, postmodern and posthuman aesthetics, or religion and the sacred in relation to community.
Historian Levine presents a vivid and distinctly human perspective on how the Jewish people survived 800 years of persecution. This is an impressive and immensely readable book, one that is an important contribution to the literature of Jewish history.
This text explains just how and why the best-of-class pump users are consistently achieving superior run lengths, low maintenance expenditures and unexcelled safety and reliability.

Since the dawn of time, man has sought to improve his health and that of his neighbour. The human race, around the world, has been on a long and complex journey, seeking to find out how our bodies work, and what heals them. Embarking on a four-thousand-year odyssey, science historian Allan Chapman brings to life the origin and development of medicine and surgery. Writing with pace and rigorous accuracy, he investigates how we have battled against injury and disease, and provides a gripping and highly readable account of the various victories and discoveries along the way. Drawing on sources from across Europe and beyond, Chapman discusses the huge contributions to medicine made by the Greeks, the Romans, the early medieval Arabs, and above all by Western Christendom, looking at how experiment, discovery, and improving technology impact upon one another to produce progress. This is a fascinating, insightful read, enlivened with many colourful characters and memorable stories of inspired experimenters, theatrical surgeons, student pranks, body-snatchers, 'mad-doctors', quacks, and charitable benefactors.
Long regarded as “the book” in the field for in-depth learning as well as decision support at the point of care, Primary Care Medicine, 8th Edition, continues its tradition as a comprehensive, evidence-based, action-oriented information resource. Presented in companion electronic format updated quarterly, its problem-based orientation spans the full spectrum of problems encountered in adult primary care practice. Chapters address screening, diagnosis, prevention and management, including indications for referral and approaches to patient education and shared decision making. Clear, practical, bulleted recommendations and an extensive annotated bibliography of best references follow detailed discussions of pathophysiology, clinical presentation, differential diagnosis, and strategies for workup and treatment. Now with its 40th-anniversary edition, this exceptional text is a must-have resource for physicians, nurse practitioners, physician assistants, students, and residents- offering the most complete and up-to-date resource available for primary care education and practice.
This textbook is designed for graduate students in mathematics, physics, engineering, and computer science. Its purpose is to guide the reader in exploring contemporary approximation theory. The emphasis is on multi-variable approximation theory, i.e., the approximation of functions in several variables, as opposed to the classical theory of functions in one variable. Most of the topics in the book, heretofore accessible only through research papers, are treated here from the basics to the currently active research, often motivated by practical problems arising in diverse applications such as science, engineering, geophysics, and business and economics. Among these topics are projections, interpolation paradigms, positive definite functions, interpolation theorems of Schoenberg and Micchelli, tomography, artificial neural networks, wavelets, thin-plate splines, box splines, ridge functions, and convolutions. An important and valuable feature of the book is the bibliography of almost 600 items directing the reader to important books and research papers. There are 438 problems and exercises scattered through the book allowing the student reader to get a better understanding of the subject.
Clinicians and students at all levels and in all primary care disciplines will benefit from the clear, practical, evidence-based writing and recommendations that address the full spectrum of clinical problems encountered in the adult primary care practice. Whether it’s the answer to a screening, prevention, evaluation, or management question or a comprehensive approach to a complex condition, the reader will find a review of best evidence integrated with considerations of affordability, cost-effectiveness, convenience and patient preference. Chapters present actionable, scientifically validated guidance that allows physicians to go beyond standard consensus guidelines and provide highly personalized care. Special consideration is given to team-based approaches of primary care delivery, recognizing its increasing importance to achieving high levels of practice performance. Primary Care Medicine’s digital format and quarterly updates ensure current, point-of-care decision support. New, online resources include a recommended curriculum for trainees and faculty, emphasizing a core knowledge base needed for all members of the primary care team, and access to state-of-the-art, condition-specific decision grids to facilitate patient participation in shared decision-making.
Now in its Sixth Edition, this comprehensive text provides pertinent information on medical diagnosis, therapy, lab tests, and health maintenance essential to decision making in primary care medicine. Every chapter has been revised to include more images, tables, and bulleted lists.
