Physics and the life sciences have established new connections within the past few decades, resulting in biological physics as an established subfield with strong groups working in many physics departments. These interactions between physics and biology form a two-way street with physics providing new tools and concepts for understanding life, while biological systems can yield new insights into the physics of complex systems. To address the challenges of this interdisciplinary area, The Physics of Proteins: An Introduction to Biological Physics and Molecular Biophysics is divided into three interconnected sections. In Parts I and II, early chapters introduce the terminology and describe the main biological systems that physicists will encounter. Similarities between biomolecules, glasses, and solids are stressed with an emphasis on the fundamental concepts of living systems. The central section (Parts III and IV) delves into the dynamics of complex systems. A main theme is the realization that biological systems, in particular proteins, do not exist in unique conformations but can assume a very large number of slightly different structures. This complexity is captured in the concept of a free energy landscape and leads to the conclusion that fluctuations are crucial for the functioning of biological systems. The final chapter of this section challenges the reader to apply these concepts to a problem that appears in the current literature. An extensive series of appendices (Part V) provide descriptions of the key physical tools and analytical methods that have proven powerful in the study of the physics of proteins. The appendices are designed to be consulted throughout the section on protein dynamics without breaking the deductive flow of the logic in the central section of the book.

This book is concerned with the physical aspects of molecular and electronic tunneling in biological systems, and the extent to which protein structure controls these events. The scope is very broad and this volume could almost be a textbook in biophysics. Both fundamental processes and the extrapolation to physiological events are stressed. The discussion sections are remarkably frank and offer insight into the basic problems confronting physists and chemists as they seek to apply their techniques to biological systems. This book on the physics of biomolecules reflects recent progress in understanding the biological function of the key protein molecules from detailed knowledge of their physics. New and exciting are the glasslike aspects of protein structures and the discussion of proteins as fractals. Other topics dealt with are low-temperature kinetics and reactivity, structure and charge exchange, and charge separation in photosynthetic reaction centers.

Tunneling in Biological Systems focuses on the low temperature electron transport that reveals a quantum-mechanical effect called "tunneling. This book discusses the tunneling in physical systems; detection of molecular vibrations with electron tunneling; chemical-rate theory of small-polaron hopping; and experimental approaches to electronic coupling in metal ion redox systems. The Faraday rotation and photoconductivity of photosynthetic structures at microwave frequencies; dynamics of electron transport in macromolecules; and electron transfer reactions in cytochrome oxidase are also elaborated. This text likewise covers the kinetic evidence for electron tunneling in solution; specificity and control in biological systems; molecular tunneling in heme proteins; and ligand binding. This publication is valuable to students and researchers interested in the physics of biological and medical problems.

This volume is devoted to the applications of techniques from statistical physics to the characterization and modeling of complex networks. The first two parts of the book concern theory and modeling of networks, the last two parts survey applications to a wide variety of natural and artificial networks. The tutorial reviews that form this book are aimed at students and newcomers to the field, and will also constitute a modern and comprehensive reference for experts. To this aim, all contributions have been carefully peer-reviewed not only for scientific content but also for self-consistency and readability.
