Excitability is an intrinsic feature of a living matter. A commonly accepted feature of an excitable medium is that a local excitation leads to a propagation of circular or spiral excitation wave-fronts. This is indeed the case in fully excitable medium. However, with a decrease of an excitability localised wave-fragments emerge and propagate ballistically. Using FitzhHugh-Nagumo model we numerically study how excitation wave-fronts behave in a geometrically constrained medium and how the wave… Expand

Disruption and recovery of reaction–diffusion wavefronts interacting with concave, fractal, and soft obstacles
Abstract In a recent publication (Smith et al., 2019), we documented the distinct recovery of reaction–diffusion wavefronts disrupted by hard convex obstacles. Here, we extend that work to includeExpand
Computing on actin bundles network
In computational experiments with a two-dimensional slice of an actin bundle network it is shown that by using an arbitrary arrangement of electrodes, it is possible to implement two-inputs-one-output circuits. Expand
On Boolean gates in fungal colony
This work uses FitzHugh-Nagumo model to imitate propagation of excitation in a single colony of Aspergillus niger, and derives sets of two-inputs-on-output logical gates implementable the fungal colony and analyse distributions of the gates. Expand
Light sensitive Belousov-Zhabotinsky medium accommodates multiple logic gates
Given that conventional or von Neumann architecture computations is proved possible on the proposed configuration, the next step would be the realization of unconventional types of computation, such as neuromorphic and fuzzy computations, where the chemical substrate may prove more efficient than silicon.

Application of Fuzzy Pushdown Automaton on Prediction of Quality Control for Spinning Yarn
The design of a suitable fuzzy pushdown automaton (FPDA) control method and the decision reasoning rules in control are given and the application of FPDA in prediction of quality control for spinning yarn is discussed. Expand


Initiation of Rotors by Fast Propagation Regions in Excitable Media: A Theoretical Study
We study the effect of geometry of a fast propagation region (FPR) in an excitable medium on the rotor initiation using a generic two-dimensional reaction-diffusion model. We find that, while theExpand
Spiral wave breakup in excitable media with an inhomogeneity of conduction anisotropy
The FitzHugh-Nagumo model of an excitable medium is used to model the conduction of the activation waves in a two-dimensional system with inhomogeneous anisotropy level to suggest that the inhomogeneity of conduction an isotropy may promote wave breakup and hence play an important role in the initiation and perpetuation of the cardiac arrhythmias.

Chemical Excitable Medium in Barcelona Street Network as a Method for Panicked Crowds Behavior Analysis
It is demonstrated that with decreasing excitability, the spanning of the street networks by an excitation wavefront shows evidence of pruning toward wider and ballistically plausible pathways. Expand
Exploring Tehran with excitable medium
It is demonstrated that excitability of the medium allows acts as a selector between omnidirectional waves and soliton-like localised excitations and a phase-transition like dynamics, controlled by the excitability, of coverage of the street network by excitation wave-fronts is uncovered. Expand
Propagation through heterogeneous substrates in simple excitable media models.
The interaction of waves and obstacles is simulated by adding heterogeneities to a FitzHugh-Nagumo model and a cellular automata model, which give insights concerning spiral wave formation in heterogeneous excitable media. Expand
Street map analysis with excitable chemical medium.
This work uses two-variable Oregonator equations, the most widely accepted and verified in laboratory experiments BZ models, to study propagation of excitation wave fronts for a range of excitability parameters, with gradual transition from excitable to subexcitable to nonexcitable. Expand
Emergence of spiral wave activity in a mechanically heterogeneous reaction-diffusion-mechanics system.
It is found that self-sustaining spiral wave activity emerges for a wide range of mechanical parameters of the inhomogeneity via five mechanisms, and how these results can be applied to understand the onset of cardiac arrhythmias due to regional mechanical heterogeneity is discussed. Expand
Wave Propagation in Inhomogeneous Excitable Media
Excitable media are ubiquitous in nature and can be found in physical, chemical, and biological systems that are far from thermodynamic equilibrium. The spatiotemporal self-organization of theseExpand

Impulses and Physiological States in Theoretical Models of Nerve Membrane.
Van der Pol's equation for a relaxation oscillator is generalized by the addition of terms to produce a pair of non-linear differential equations with either a stable singular point or a limit cycle, which qualitatively resembles Bonhoeffer's theoretical model for the iron wire model of nerve.
