The resonance behaviors, such as coherence resonance and stochastic resonance, are studied in a delayed bistable system subject to correlated noises and a weak harmonic excitation. For weak noise intensities and small feedback gains, the analytic expressions of output spectrum and linear...

Multiplicative stochastic resonance in linear systems with delay is studied for the discrete case. The overdamped linear system with symmetric multiplicative Markovian dichotomous noise (DN) is considered. The stability range of the solutions for different values of delay is analyzed. The...

We consider the overdamped version of two coupled anharmonic oscillators with the external periodic force fsinωt and Gaussian noise term η(t) added to one of the two state variables of the system. Linear stability analysis is carried out in the absence of external periodic force and noise....

In many cell types, intracellular calcium is released from internal stores through calcium release channels which are distributed in clusters with a few tens of channels. Localized calcium release events, i.e. Ca2 + puffs, are subjected to stochastic channel dynamics and fluctuations of...

In this paper, we investigate the Sznajd model of opinion dynamics with anticonformity on a complete graph. We show that below some threshold value of anticonformal behavior spontaneous reorientations occur between two stable states. Dealing with a complete graph allows us also for an analytical...

In this paper, we consider the phenomenon of stochastic resonance (SR) in an asymmetric bistable system with coloured noises and periodic rectangular signal. Expression of the signal-to-noise ratio (SNR) has been obtained under the adiabatic limit. We investigate the effect of any system...

The phenomenon of stochastic resonance (SR) is reported in a completely noise-free situation, with the role of thermal noise being taken by low-dimensional chaos. A one-dimensional, piecewise linear map and a pair of coupled excitatory-inhibitory neurons are the systems used for the...

We present experimental results on the information transmission and storage via stochastic resonance in circuits designed and built around Schmitt triggers (STs). First, we investigate the performance of a transmission line comprised of five STs and show it to exhibit stochastic resonance. Each...

The effect of diversity on a system of coupled threshold elements is investigated, where each element is driven by a common periodic signal. Diversity is introduced to the system by assuming that the thresholds of all units are heterogeneous, e.g. the thresholds follow a Gaussian or other...

We have recently shown that a stochastic driving in an opinion spreading model has a tremendous impact on the system dynamics, spontaneously leading to system's agents which are analogous to Galam's contrarians. We have analyzed the existence of stochastic resonance phenomena in this social...
