Book Description
This book aims to cover a broad range of topics in statistical physics, including statistical mechanics (equilibrium and non-equilibrium), soft matter and fluid physics, for applications to biological phenomena at both cellular and macromolecular levels. It is intended to be a graduate level textbook, but can also be addressed to the interested senior level undergraduate. The book is written also for those involved in research on biological systems or soft matter based on physics, particularly on statistical physics. Typical statistical physics courses cover ideal gases (classical and quantum) and interacting units of simple structures. In contrast, even simple biological fluids are solutions of macromolecules, the structures of which are very complex. The goal of this book to fill this wide gap by providing appropriate content as well as by explaining the theoretical method that typifies good modeling, namely, the method of coarse-grained descriptions that extract the most salient features emerging at mesoscopic scales. The major topics covered in this book include thermodynamics, equilibrium statistical mechanics, soft matter physics of polymers and membranes, non-equilibrium statistical physics covering stochastic processes, transport phenomena and hydrodynamics. Generic methods and theories are described with detailed derivations, followed by applications and examples in biology. The book aims to help the readers build, systematically and coherently through basic principles, their own understanding of nonspecific concepts and theoretical methods, which they may be able to apply to a broader class of biological problems.

Book Description
A physicist's guide to the phenomena of life Interactions between the fields of physics and biology reach back over a century, and some of the most significant developments in biology—from the discovery of DNA's structure to imaging of the human brain—have involved collaboration across this disciplinary boundary. For a new generation of physicists, the phenomena of life pose exciting challenges to physics itself, and biophysics has emerged as an important subfield of this discipline. Here, William Bialek provides the first graduate-level introduction to biophysics aimed at physics students. Bialek begins by exploring how photon counting in vision offers important lessons about the opportunities for quantitative, physics-style experiments on diverse biological phenomena. He draws from these lessons three general physical principles—the importance of noise, the need to understand the extraordinary performance of living systems without appealing to finely tuned parameters, and the critical role of the representation and flow of information in the business of life. Bialek then applies these principles to a broad range of phenomena, including the control of gene expression, perception and memory, protein folding, the mechanics of the inner ear, the dynamics of biochemical reactions, and pattern formation in developing embryos. Featuring numerous problems and exercises throughout, Biophysics emphasizes the unifying power of abstract physical principles to motivate new and novel experiments on biological systems. Covers a range of biological phenomena from the physicist's perspective Features 200 problems Draws on statistical mechanics, quantum mechanics, and related mathematical concepts Includes an annotated bibliography and detailed appendixes

Book Description
This book presents an extensive treatment of the introduction of modern physical concepts into biology. In particular, the concept of coherence finds wide applications and yields novel results in context with multiple problems as they arise in biology: these include long range resonant cellular effects and resonant interactions of biological tissues with low intensity electro-magnetic radiation. Extensive experimental support of the theoretical concept is presented.

Book Description
Biophysics is a new way of looking at living matter. It uses quantitative experimental and theoretical methods to open a new window for studying and understanding life processes. This textbook gives compact introductions to the basics of the field, including molecular cell biology and statistical physics. It then presents in-depth discussions of more advanced biophysics subjects, progressing to state-of-the-art experiments and their theoretical interpretations. The book is unique by offering a general introduction to biophysics, yet at the same time restricting itself to processes that occur inside the cell nucleus and that involve biopolymers (DNA, RNA, and proteins). This allows for an accessible read for beginners and a springboard for specialists who wish to continue their study in more detail.

Book Description
Theoretical chemistry has been an area of tremendous expansion and development over the past decade; from an approach where we were able to treat only a few atoms quantum mechanically or make fairly crude molecular dynamics simulations, into a discipline with an accuracy and predictive power that has rendered it an essential complementary tool to experiment in basically all areas of science. This volume gives a flavour of the types of problems in biochemistry that theoretical calculations can solve at present, and illustrates the tremendous predictive power these approaches possess.A wide range of computational approaches, from classical MD and Monte Carlo methods, via semi-empirical and DFT approaches on isolated model systems, to Car-Parinello QM-MD and novel hybrid QM/MM studies are covered. The systems investigated also cover a broad range; from membrane-bound proteins to various types of enzymatic reactions as well as inhibitor studies, cofactor properties, solvent effects, transcription and radiation damage to DNA.

Book Description
This book is an introduction to the mechanical properties, the force generating capacity, and the sensitivity to mechanical cues of the biological system. To understand how these qualities govern many essential biological processes, we also discuss how to measure them. However, before delving into the details and the techniques, we will first learn the operational definitions in mechanics, such as force, stress, elasticity, viscosity and so on. This book will explore the mechanics at three different length scales – molecular, cellular, and tissue levels – sequentially, and discuss the measurement techniques to quantify the intrinsic mechanical properties, force generating capacity, mechanoresponsive processes in the biological systems, and rupture forces.

Book Description
This book serves as an introduction to the continuum mechanics and mathematical modeling of complex fluids in living systems. The form and function of living systems are intimately tied to the nature of surrounding fluid environments, which commonly exhibit nonlinear and history dependent responses to forces and displacements. With ever-increasing capabilities in the visualization and manipulation of biological systems, research on the fundamental phenomena, models, measurements, and analysis of complex fluids has taken a number of exciting directions. In this book, many of the world’s foremost experts explore key topics such as: Macro- and micro-rheological techniques for measuring the material properties of complex biofluids and the subtleties of data interpretation Experimental observations and rheology of complex biological materials, including mucus, cell membranes, the cytoskeleton, and blood The motility of microorganisms in complex fluids and the dynamics of active suspensions Challenges and solutions in the numerical simulation of biologically relevant complex fluid flows This volume will be accessible to advanced undergraduate and beginning graduate students in engineering, mathematics, biology, and the physical sciences, but will appeal to anyone interested in the intricate and beautiful nature of complex fluids in the context of living systems.

Book Description
The Lagrangian approach had, in many respects, yielded significant success of theoretical physics in the centuries following its discovery. Unfortunately, the Lagrangian equations, in its original form, cannot be applied to living systems. For a time-independent Lagrangian, these equations are time-reversible and lead to energy conservation, which undoubtedly is not true for the living objects. In this book we show that natural (although rather unexpected) generalization of the Lagrangian enables directly use the apparatus of Lagrangian dynamics to describe behavior the living objects. It is, ultimately, not a revolutionary modification. Rather, lost opportunity that was not considered in the development of contemporary physics has been revisited. The main difference between living creatures and non-living things is that life actively counteracts its degradation in a continuously changing environment. Attempting to minimize the likelihood of death is a basic feature of living organisms. In this book, we assume that the best candidate for an indicator of proximity to death is stress, which is naturally related to the undesirable states of an organism. It will be shown that such an assumption facilitates the design of the generalized Lagrangians and that exploring even the lowest approximation of the Lagrangians allows for a reasonable description of a wide class of behavior of living beings, ranging from bacterial chemotaxis to homeostasis, dominance a hierarchy formation in the social groups and behavior of living being in environment. Although the book intendent, mainly, for young physicists and mathematicians, whose seek promising areas to apply their professional skills, experienced researchers would find here novel powerful theoretical apparatus for their investigation.
