The dynamic behavior of epithelial cell sheets plays a central role during numerous
developmental processes. Genetic and imaging studies of epithelial morphogenesis in a …

Dynamics is central to living systems. Many experiments in the last two decades have
revealed glassy dynamics in diverse biological systems, showing a transition between a …

The kinetics of grain growth in two-dimensions (2-D) were investigated by computer
simulations based on a continuum diffuse-interface field model. In this model, a …

Computer modelling has been carried out to study normal grain growth in three dimensions.
The approach consists of digitizing the microstructure by dividing the polycrystalline material …

To elucidate the mechanisms of grain growth in nanocrystalline fcc metals, we have
performed fully three-dimensional molecular-dynamics simulations with a columnar grain …

A large class of evolving nonequilibrium systems, known collectively as cellular structures,
are composed of nearly-uniform domains of polygonal-like or polyhedral-like shape (in two …

We have studied experimentally the dynamics of soap froths in two dimensions. We observe
two temporal regimes: a transient in which the average bubble area increases in time faster …

Many materials, including soap froths, polycrystalline alloys, ceramics, lipid monolayers and
garnet films, have structures composed of either two-or three-dimensional polygonal …

A detailed comparison between the experimental evolution of a two-dimensional soap froth
and a next-nearest-neighbour Q=∞ Potts model on a square lattice starting from identical …

In this Letter we study the evolution of a two-dimensional soap froth. We present
experimental evidence for the existence of a limiting scale-invariant distribution of the …
