Abstract

Motivated by the dynamics of twisted biopolymers such as DNA and filaments of Bacillus subtilis, we formulate the over‐damped dynamics of a twisted elastic rod. The development exploits the β€˜natural’ frame, in which curve dynamics are described by a pair of non‐linear partial differential equations, partitioning bending from twisting motions and highlighting their geometric interplay. A number of open problems are highlighted, along with connections with questions about cellular structure and statistical dynamics. Copyright Β© 2001 John Wiley & Sons, Ltd.

A distribution function, using dynamical weights, proposed previously to describe statistical mechanical systems in stationary states, is discussed from a physical point of view. The distribution function correctly describes certain large current fluctuations far from equilibrium, observed in two co

We study a master equation system modelling a population dynamics problem in a lattice. The problem is the calculation of the minimum size of a refuge that can protect a population from hostile external conditions, the so-called critical patch size problem. We analyse both cases in which the particl
