A quite simple but useful approach is performed for the analysis of chemical wave segments with free ends. By integrating a reaction-diffusion system we can obtain an analytical expression to understand the dynamics of the wave segments. This inte...

A surface deformation wave coupled with an oscillatory hydrodynamic flow is observed in a thin solution layer of the Belousov-Zhabotinsky reaction. The observation is carried out with a Mach-Zehnder interferometric system under the excitation of c...

The present paper proposes a computational model for the realization of visual functions of edge and/or feature detection and segmentation. The model utilizes a reaction-diffusion model which is an extended version of the diffusion-based Differenc...

The excitable Belousov-Zhabotinsky (BZ) reaction coupled with diffusion can exhibit a large variety of spatial patterns. In this letter, we report on superimposed spiral structures, providing evidence of a hierarchical self-organized order that co...

An increasing attention is focused on information processing by reaction-diffusion system, in which temporal and spatial patterns are self-organized. In the system, two interesting phenomena of Turing pattern formation and stochastic resonance hav...
