TLDR
Analysis is given of ''elementary'' cellular automata consisting of a sequence of sites with values 0 or 1 on a line, with each site evolving deterministically in discrete time steps according to p definite rules involving the values of its nearest neighbors.Abstract:
Cellular automata are used as simple mathematical models to investigate self-organization in statistical mechanics. A detailed analysis is given of "elementary" cellular automata consisting of a sequence of sites with values 0 or 1 on a line, with each site evolving deterministically in discrete time steps according to definite rules involving the values of its nearest neighbors. With simple initial configurations, the cellular automata either tend to homogeneous states, or generate self-similar patterns with fractal dimensions \ensuremath{\simeq} 1.59 or \ensuremath{\simeq} 1.69. With "random" initial configurations, the irreversible character of the cellular automaton evolution leads to several self-organization phenomena. Statistical properties of the structures generated are found to lie in two universality classes, independent of the details of the initial state or the cellular automaton rules. More complicated cellular automata are briefly considered, and connections with dynamical systems theory and the formal theory of computation are discussed.read more

Discrete systems, cell-cell interactions and color pattern of animals. I. Conflicting dynamics and pattern formation.
TL;DR: The morphogenesis of the color pattern of animals is modeled within the framework of a clonal model that takes into account the, sometimes conflicting, cell-cell and cell-background interactions.

A cellular automaton model for microcarrier cultures.
TL;DR: A cellular automaton approach is recommended to model the growth of anchorage‐dependent cells on microcarriers and can be used to generate contact‐inhibition growth curves to decouple the effect of contact‐ inhibition from growth kinetics.

A cellular automaton model for ship traffic flow in waterways
Le Qi,Zhongyi Zheng,Longhui Gang +2 more
TL;DR: The simulations show that the SLM model could avoid ship pseudo lane-change efficiently, which is caused by traditional spatial discretization rules, and the relationship between traffic ability and the lengths of ships is explored.

Random Boolean network model exhibiting deterministic chaos.
TL;DR: This paper considers a simple Boolean network with N nodes, each node's state at time t being determined by a certain number of parent nodes, which may vary from one node to another, and provides a generalization of the formula for the probability of finding a node in state 1 at a time t.

Metabolic stability and epigenesis in randomly constructed genetic nets
TL;DR: The hypothesis that contemporary organisms are also randomly constructed molecular automata is examined by modeling the gene as a binary (on-off) device and studying the behavior of large, randomly constructed nets of these binary “genes”.

Diffusion-limited aggregation, a kinetic critical phenomenon
Abstract: A model for random aggregates is studied by computer simulation The model is applicable to a metal-particle aggregation process whose correlations have been measured previously Density correlations within the model aggregates fall off with distance with a fractional power law, like those of the metal aggregates The radius of gyration of the model aggregates has power-law behavior The model is a limit of a model of dendritic growth
