Simple dynamical model with history dependence for a sandpile experiment
Shuji Ishihara, Kunihiko Kaneko
A lattice dynamics model is proposed for the history dependence observed in sandpile experiments. The dependence of the stress distribution on the preparation of the sandpile is ex…
Alteration of Chemical Concentrations through Discreteness-Induced Transitions in Small Autocatalytic Systems
Yuichi Togashi, Kunihiko Kaneko
We study an autocatalytic system consisting of several interacting chemical species. We observe a strong dependence of the concentrations of the chemicals on the size of the system…
Spontaneous structure formation in a network of chaotic units with variable connection strengths
Junji Ito, Kunihiko Kaneko
As a model of temporally evolving networks, we consider a globally coupled logistic map with variable connection weights. The model exhibits self-organization of network structure,…
How Fast Elements can Affect Slow Dynamics
Koichi Fujimoto, Kunihiko Kaneko
A chain of coupled chaotic elements with different time scales is studied. In contrast with the adiabatic approximation, we find correlations between faster and slower elements whe…
Origin of genetic information from minority control in a replicating system with mutually catalytic molecules
Kunihiko Kaneko, Tetsuya Yomo
As the first step in an investigation of the origin of genetic information, we study how some species of molecules are preserved over cell generations and play an important role in…
Differentiation and Replication of Spots in a Reaction Diffusion System with Many Chemicals
Hiroaki Takagi, Kunihiko Kaneko
The replication and differentiation of spots in reaction diffusion equations are studied by extending the Gray-Scott model with self-replicating spots to include many degrees of fr…
