Book Description
Computer simulations have provided a wealth of information concerning a wide range of systems. The precision of computer simulation results depends on the degree of sampling (time scales) achieved, while the accuracy of the results (given sufficient sampling) depends on the quality of force field used. A force field provides a description of the energy for a system of interest. Recently, we have been developing a Kirkwood Buff (KB) force field for molecular dynamics simulations of biological systems. This force field is based on the KB Theory of solutions, emphasizing the accurate description of intermolecular interactions, and reasonably reproducing a range of other physical properties from experiment. In this approach simulation results in terms of KB integrals can be directly compared with experimental data through a KB analysis of the solution properties. The approach therefore provides a simple and clear method to test the capability of a force field. Here we firstly studied a series of alcohol-water mixtures in an attempt to validate the transferability and additivity of the force field. A general fluctuation theory was applied to investigate the properties of these systems, and to compare with computer simulation results. The possible effects of cosolvents on peptides and proteins were then investigated using N-methylacetamide as model for the peptide backbone and urea as cosolvent. A possible explanation for the urea denaturation of protein structure was provided using a thermodynamics point of view involving transfer free energies and preferential interactions obtained from the KB integrals. Finally, potentials for protein backbone and sidechain torsions were developed by fitting to quantum mechanical calculations and NMR data. Simulations of a variety of peptides and proteins in aqueous solutions were then performed to demonstrate the overall reliability of the force field.

Book Description
This book describes the mathematical underpinnings of algorithms used for molecular dynamics simulation, including both deterministic and stochastic numerical methods. Molecular dynamics is one of the most versatile and powerful methods of modern computational science and engineering and is used widely in chemistry, physics, materials science and biology. Understanding the foundations of numerical methods means knowing how to select the best one for a given problem (from the wide range of techniques on offer) and how to create new, efficient methods to address particular challenges as they arise in complex applications. Aimed at a broad audience, this book presents the basic theory of Hamiltonian mechanics and stochastic differential equations, as well as topics including symplectic numerical methods, the handling of constraints and rigid bodies, the efficient treatment of Langevin dynamics, thermostats to control the molecular ensemble, multiple time-stepping, and the dissipative particle dynamics method.

Book Description
Protein engineering endeavors to design new peptides and proteins or to change the structural and/or functional characteristics of existing ones for specific purposes, opening the way for the development of new drugs. This work develops in a comprehensive way the theoretical formulation for the methods used in computer-assisted modeling and predictions, starting from the basic concepts and proceeding to the more sophisticated methods, such as Monte Carlo and molecular dynamics. An evaluation of the approximations inherent to the simulations will allow the reader to obtain a perspective of the possible deficiencies and difficulties and approach the task with realistic expectations. Examples from the authors laboratories, as well as from the literature provide useful information.

Book Description
The behaviour of many complex materials extends over time- and lengthscales well beyond those that can normally be described using standard molecular dynamics or Monte Carlo simulation techniques. As progress is coming more through refined simulation methods than from increased computer power, this volume is intended as both an introduction and a review of all relevant modern methods that will shape molecular simulation in the forthcoming decade. Written as a set of tutorial reviews, the book will be of use to specialists and nonspecialists alike.

Book Description
Experts provide a unique and broad perspective of the theoretical tools available today to analyze protein structure and function. Topics at the frontier of computational biophysics, such as dynamics and thermodynamics of proteins, reaction path studies, optimization techniques, analytical theories of protein folding, sequence alignment algorithms and electrostatics of proteins are discussed in a pedagogical and complete way. Those entering the field will find the book to be a useful introduction. It will also serve as a complementary text to existing ones that focus on just one of the above subjects.

Book Description
Bayesian statistics is a powerful method for inference--possibly the uniquely correct method for inference. As described herein, when applied to a few degrees of freedom from single molecule trajectories, Bayesian statistics yield useful insights into rates, states, and motions.
