Reaction-diffusion in a growing 3D domain of skin scales generates a discrete cellular automaton. [PDF]
Nat Commun, 2021 We previously showed that the adult ocellated lizard skin colour pattern is effectively generated by a stochastic cellular automaton (CA) of skin scales. We additionally suggested that the canonical continuous 2D reaction-diffusion (RD) process of colour

Cellular automaton decoders for topological quantum codes with noisy measurements and beyond. [PDF]
Sci Rep, 2021 We propose an error correction procedure based on a cellular automaton, the sweep rule, which is applicable to a broad range of codes beyond topological quantum codes.

Modeling and analyzing malware diffusion in wireless sensor networks based on cellular automaton
International Journal of Distributed Sensor Networks, 2020 Wireless sensor networks, as a multi-hop self-organized network system formed by wireless communication, are vulnerable to malware diffusion by breaking the data confidentiality and service availability, owing to their low configuration and weak defense ...

Phase Space Invertible Asynchronous Cellular Automata [PDF]
Electronic Proceedings in Theoretical Computer Science, 2012 While for synchronous deterministic cellular automata there is an accepted definition of reversibility, the situation is less clear for asynchronous cellular automata.

From quantum cellular automata to quantum lattice gases [PDF]
J. Stat. Phys. 85 (1996) 551-574, 1996 A natural architecture for nanoscale quantum computation is that of a quantum cellular automaton. Motivated by this observation, in this paper we begin an investigation of exactly unitary cellular automata. After proving that there can be no nontrivial, homogeneous, local, unitary, scalar cellular automaton in one dimension, we weaken the homogeneity ...

Growth of surfaces generated by a probabilistic cellular automaton [PDF]
, 1998 A one-dimensional cellular automaton with a probabilistic evolution rule can generate stochastic surface growth in $(1 + 1)$ dimensions. Two such discrete models of surface growth are constructed from a probabilistic cellular automaton which is known to show a transition from a active phase to a absorbing phase at a critical probability associated with

On the decomposition of stochastic cellular automata [PDF]
arXiv, 2015 In this paper we present two interesting properties of stochastic cellular automata that can be helpful in analyzing the dynamical behavior of such automata. The first property allows for calculating cell-wise probability distributions over the state set of a stochastic cellular automaton, i.e. images that show the average state of each cell during the

One Dimensional $n$ary Density Classification Using Two Cellular Automaton Rules [PDF]
, 1998 Suppose each site on a one-dimensional chain with periodic boundary condition may take on any one of the states $0,1,..., n-1$, can you find out the most frequently occurring state using cellular automaton? Here, we prove that while the above density classification task cannot be resolved by a single cellular automaton, this task can be performed ...

A cellular automaton model for spheroid response to radiation and hyperthermia treatments. [PDF]
Sci Rep, 2019 Thermo-radiosensitisation is a promising approach for treatment of radio-resistant tumours such as those containing hypoxic subregions. Response prediction and treatment planning should account for tumour response heterogeneity, e.g.

Cellular automata and Lyapunov exponents [PDF]
Nonlinearity 13 (2000) 1547-1560, 2003 In this article we give a new definition of some analog of Lyapunov exponents for cellular automata . Then for a shift ergodic and cellular automaton invariant probability measure we establish an inequality between the entropy of the automaton, the entropy of the shift and the Lyapunov exponent.
