This book is a lucid, straightforward introduction to the concepts and techniques of statistical physics that students of biology, biochemistry, and biophysics must know. It provides a sound basis for understanding random motions of molecules, subcellular particles, or cells, or of processes that depend on such motion or are markedly affected by it. Readers do not need to understand thermodynamics in order to acquire a knowledge of the physics involved in diffusion, sedimentation, electrophoresis, chromatography, and cell motility--subjects that become lively and immediate when the author discusses them in terms of random walks of individual particles.read more

Mechanistic movement models to understand epidemic spread.
TL;DR: The effect of the different types of movement on the threshold conditions for disease spread is summarized and several promising directions for future research are suggested.
Journal ArticleDOI
Kinematics of the swimming of Spiroplasma.
TL;DR: Spiroplasma swimming is studied with a simple model based on resistive-force theory that considers a bacterium shaped in the form of a helix that propagates traveling-wave distortions which flip the handedness of the helical cell body and finds that scaling collapses the swimming velocity to a universal curve.

A Mechanistic Model for the Organization of Microtubule Asters by Motor and Non-Motor Proteins in a Mammalian Mitotic Extract
TL;DR: This model proposes a precise mechanism of action of each noncentrosomal protein during micro Tubule aster organization and suggests that microtubule organization in spindles involves both motile forces from motors and static forces from non-motor cross-linking proteins.

TL;DR: It is revealed that differences in cell body shape are correlated with a diverse range of cell behaviors contributing to the directional motion of the cell, possibly resulting from varying body stiffness.

Lability and mobility effects on mixtures of ligands under steady-state conditions
TL;DR: In this paper, the steady-state flux arriving at an active surface from a mixture (in which one active species reacts with non-active ligands in the medium) can be characterized in terms of a list of dimensionless parameters involving the kinetic and mobility properties of each species.
