A two-state system driven by two inputs has been found to consistently produce a response
mirroring a logic function of the two inputs, in an optimal window of moderate noise. This …

In this work, we report a fully CMOS-compatible single silicon neuron device, by exploiting
interlinked positive and negative feedback loops. The neuron device exhibits the key …

Using a nonlinear circuit ruled by the FitzHugh–Nagumo equations, we experimentally
investigate the combined effect of noise and a biharmonic driving of respective high and low …

Order-chaos-order was observed in the relaxation oscillations of a glow discharge plasma
with variation in the discharge voltage. The first transition exhibits an inverse homoclinic …

We report on the experimental observation of canard orbit and mixed mode oscillations
(MMOs) in an excitable glow discharge plasma induced by an external magnetic field …

Glow discharge plasma in the excitable regime shows rich dynamical behavior under
external forcing. By perturbing the plasma with a subthreshold sawtooth periodic signal, we …

Recently, it has been observed [Md. Nurujjaman, Phy. Rev. E 80, 015201 (R)(2009)] that in
an excitable system, one can maintain noise-induced coherency in the coherence …

The experimental characteristics of sensors of nonelectrical quantities (temperature,
magnetic field, light, and pressure) based on a unijunction transistor (UJT), which is a …

We herein present a numerical investigation of the combined effects of parameter
heterogeneity and noise, which are unavoidable in excitable medium, on spatial coherence …

We analyze the response of a nonlinear circuit exactly ruled by the FitzHugh-Nagumo
equations. This circuit is submitted to a bichromatic signal including a high frequency and a …
