The formation and dynamics of long living metastable structures, the pressure tensor and diffusion properties of a simple particle system confined by a (infinite) nanopore with rectangular cross section is investigated using molecular dynamics simulation. The system is characterized by a short...

Recently, a cellular automata model has been introduced (Phys. Rev. Lett. 87 (2001) 168102) to describe the spread of the HIV infection among target cells in lymphoid tissues. The model reproduces qualitatively the entire course of the infection displaying, in particular, the two time scales...

A new model is presented of a patterning mechanism in animals. It is argued that the ‘Wnt’ signaling pathway often acts in binary conjunction with a variety of other pathways to produce complex patterning. This patterning follows while involving little of the detailed biochemistry of either...

We study the pattern dynamics in a reaction–diffusion model of the activator–inhibitor type in the oscillatory regime. We consider finite systems with partially absorptive boundary conditions analysing examples in different geometries in one and two dimensions. We observe that the boundary...

The morphology diagram of ice crystal patterns, which grow freely in a supercooled water is obtained experimentally in a “supercooling-tip velocity” phase space. This diagram classifies eight nonequilibrium macroscopic structures growing in the supercooling temperature region of...

Surface instability in a thin liquid film engendered by a micro-scale wettability contrast, resulting from the spatial gradients in the intermolecular interactions, is investigated based on 3D simulations for a system displaying both the primary and secondary minima in its force vs. distance...

We present an experimental study about the Faraday instability using a highly dissipative fluid. The fluid layer is excited with a vertical periodic acceleration field. In this regimen of high viscosity and shallow fluid depth, we have found two very interesting phenomena. On the one hand, we...
