Topological solitons occur in many nonlinear classical field theories. They are stable, particle-like objects, with finite mass and a smooth structure. Examples are monopoles and Skyrmions, ...Ginzburg-Landau vortices and sigma-model lumps, and Yang-Mills instantons. This book is a comprehensive survey of static topological solitons and their dynamical interactions. Particular emphasis is placed on the solitons which satisfy first-order Bogomolny equations. For these, the soliton dynamics can be investigated by finding the geodesics on the moduli space of static multi-soliton solutions. Remarkable scattering processes can be understood this way. The book starts with an introduction to classical field theory, and a survey of several mathematical techniques useful for understanding many types of topological soliton. Subsequent chapters explore key examples of solitons in one, two, three and four dimensions. The final chapter discusses the unstable sphaleron solutions which exist in several field theories.
Biophysics is an evolving, multidisciplinary subject which applies physics to biological systems and promotes an understanding of their physical properties and behaviour. Biophysics: An Introduction, ...is a concise balanced introduction to this subject. Written in an accessible and readable style, the book takes a fresh, modern approach with the author successfully combining key concepts and theory with relevant applications and examples drawn from the field as a whole. Beginning with a brief introduction to the origins of biophysics, the book takes the reader through successive levels of complexity, from atoms to molecules, structures, systems and ultimately to the behaviour of organisms. The book also includes extensive coverage of biopolymers, biomembranes, biological energy, and nervous systems. The text not only explores basic ideas, but also discusses recent developments, such as protein folding, DNA/RNA conformations, molecular motors, optical tweezers and the biological origins of consciousness and intelligence. Biophysics: An Introduction* Is a carefully structured introduction to biological and medical physics * Provides exercises at the end of each chapter to encourage student understanding Assuming little biological or medical knowledge, this book is invaluable to undergraduate students in physics, biophysics and medical physics. The book is also useful for graduate students and researchers looking for a broad introduction to the subject.
Containing a Preface, 3 Chpts, & a Conclusion, this book presents a study of etymological research from the nineteenth & twentieth centuries & compares this to studies from Antiquity & the Middle ...Ages. It is asserted that etymology is experiencing a period of crisis. From its zenith at the end of the nineteenth century, etymology is no longer presented as an isolated discipline, although it is included in fundamental courses in general linguistics. It is believed that etymology is accepted superficially in dictionaries, but is discouraged in lengthy monographs because of its intrinsic nature. The book is organized chronologically: Chpt 1 covers the nineteenth century, Chpt 2, the first half of the twentieth century, & Chpt 3, the second half of the twentieth century. Bibliog. M. Gordon
This vol in the Cambridge Textbooks in Linguistics series is an updated & revised second edition containing both the preface to the first edition & a new preface, & 12 Chpts. The emphasis is ...theoretical & broad-ranging, covering inflection, derivation, compounding, morphophonemics, paradigms, & iconicity. Examples from both ancient & modern languages are discussed, centering on current issues. B. Annesser Murray
