Noise permeates biology on all levels, from the most basic molecular, sub-cellular
processes to the dynamics of tissues, organs, organisms and populations. The functional …

This paper is an introductory review of the problem of front propagation into unstable states.
Our presentation is centered around the concept of the asymptotic linear spreading velocity …

In nature, microorganisms must often cope with hostile environmental conditions. To do so
they have developed sophisticated cooperative behaviour and intricate communication …

Patterns found at driven interfaces add richness and beauty to the visual world, but they
build processing-history-dependent inhomogeneities into samples of materials whose …

We present a mean-field theory for the evolution of RNA virus populations. The theory
operates with a distribution of the population in a one-dimensional fitness space, and is valid …

Recently, polymer crystallization in ultrathin films (thickness less than 100nm) on solid
substrates has attracted increased attention. As it can be considered to be a quasi-two …

Propagating fronts are seen in varieties of nonequilibrium pattern forming systems in
Physics, Chemistry and Biology. In the last two decades, many researchers have contributed …

The problem of velocity selection for reaction fronts has been intensively investigated,
leading to the successful marginal stability (MS) approach for propagation into an unstable …

The formation of complex patterns in many non-equilibrium systems, ranging from solidifying
alloys to multiphase flow, nonlinear chemical reactions and the growth of bacterial colonies …

We study the formation of spot patterns seen in bacterial colonies when the bacteria are
subjected to oxidative stress due to hazardous by-products of respiration. The cell density is …
