An understanding of the generalized mechanism of selfreproduction is fundamental to applications in various fields, such as the mass-production of molecular machines in nanotechnology. We have developed a model for the simulation of cellular self-reproduction in a two-dimensional cellular automaton, and we have demonstrated that the following three functions can be realized: (1) formation of a ...
The transient nature of spatiotemporal chaos is examined in reaction-diffusion systems with coexisting stable states. We find the apparent asymptotic spatiotemporal chaos of the Gray-Scott system to be transient, with the average transient lifetime increasing exponentially with medium size. The collapse of spatiotemporal chaos arises when statistical spatial correlations produce a quasihomogene...

In this article we propose a unified framework in order to study reaction–diffusion systems containing self- and cross-diffusion using free energy approach. This naturally leads the formulation of an law, numerical method respecting discrete version latter. It constitutes alternative complements standard linear stability analysis, as it allows for nonlinear patterns, while monitoring evolution,...
Scattering of particlelike patterns in dissipative systems is studied, especially we focus on the issue how the input-output relation is controlled at a head-on collision in the one-dimensional(1D) space where traveling pulses interact strongly. It remains an open problem due to the large deformation of patterns at a colliding point. We found that a special type of steady or time-periodic solut...
A broad class of soil fungi form the annular patterns known as 'fairy rings' and provide one of the only means to observe spatio-temporal dynamics of otherwise cryptic fungal growth processes in natural environments. We present observations of novel spiral and rotor patterns produced by fairy ring fungi and explain these behaviors mathematically by first showing that a well known model of fairy...
Scattering of particle-like patterns in dissipative systems is studied, especially we focus on the issue how the input-output relation is controlled at a head-on collision where traveling pulses or spots interact strongly. It remains an open problem due to the large deformation of patterns at a colliding point. We found that a special type of unstable steady or time-periodic solutions called sc...
In this article, a study of long-term behavior reaction–diffusion systems augmented with self- and cross-diffusion is reported, using an Gray–Scott system as generic example. The methodology remains general, therefore applicable to some other systems. Simulations the temporal model (nonlinear parabolic system) reveal presence steady states, often associated energy dissipation. A Newton method b...
