A new mechanism for dendritic pattern formation in dense systems

Patterns are often formed when particles cluster: Since patterns reflect the connectivity of different types of material, the emergence of patterns affects the physical and chemical properties of systems and shares a close relationship to their macroscopic functions. A radial dendritic pattern (RDP) is observed in many systems such as snow crystals, polymer crystals and biological systems. Alth...

Variational Algorithms and Pattern Formation in Dendritic Solidiication

We present a completely new variational algorithm for computing den-dritic solidiication. This algorithm reproduces the Gibbs-Thomson relation as a balance between bulk and surface energy, and is able to operate in the innnite-mobility limit with no unphysical time-step restriction. It may be used with arbitrary non-smooth surface energy functions, and may include nite kinetic mobility. We perf...

Single-electron Circuits Performing Dendritic Pattern Formation with Nature-Inspired Cellular Automata

We propose a novel semiconductor device in which electronic-analogue dendritic trees grow on multilayer single-electron circuits. A simple cellular-automaton circuit was designed for generating dendritic patterns by utilizing the physical properties of single-electron devices, i.e. quantum and thermal effects in tunneling junctions. We demonstrate typical operations of the proposed circuit thro...

Nearest pattern interaction and global pattern formation

We studied the effect of nearest pattern interaction on a global pattern formation in a two-dimensional space, where patterns are to grow initially from a noise in the presence of a periodic supply of energy. Although our approach is general, we found that this study is relevant in particular to the pattern formation on a periodically vibrated granular layer, as it gives a unified perspective o...

Protein Pattern Formation

Protein pattern formation is essential for the spatial organization of many intracellular processes like cell division, flagellum positioning, and chemotaxis. A prominent example of intracellular patterns are the oscillatory pole-to-pole oscillations of Min proteins in E. coli whose biological function is to ensure precise cell division. Cell polarization, a prerequisite for processes such as s...
