Single-Molecule Stochastic Resonance [PDF]
Physical Review X, 2012 Stochastic resonance (SR) is a well-known phenomenon in dynamical systems. It consists of the amplification and optimization of the response of a system assisted by stochastic (random or probabilistic) noise.

Stochastic resonance in a dipole [PDF]
Physical Review E, 1996 We show that the dipole, a system usually proposed to model relaxation phenomena, exhibits a maximum in the signal-to-noise ratio at a non-zero noise level, thus indicating the appearance of stochastic resonance. The phenomenon occurs in two different situations, i.e.

Synchronization of Chaos in Neural Systems
Frontiers in Applied Mathematics and Statistics, 2020 Multiple non-linear systems demonstrate the phenomenon where fluctuations enhance the synchronization and periodic behaviors of the system. In the phenomenon induced by stochastic additive noise, stochastic resonance, noise enhances the synchronization ...

Stochastic resonance in perspective [PDF]
Il Nuovo Cimento D, 1995 We outline the historical development of stochastic resonance (SR), a phenomenon in which the signal and/or the signal-to-noise ratio in a nonlinear system increase with increasing intensity of noise. We discuss basic theoretical ideas explaining and describing SR, and we review some revealing experimental data that place SR within the wider context of

Stochastic resonance: from climate to biology [PDF]
Nonlinear Processes in Geophysics, 2010 In this lecture, I will review some basic aspects of the mechanism of stochastic resonance, first introduced as a possible mechanism to explain long term climatic variation.

Entropic Stochastic Resonance [PDF]
Physical Review Letters, 2008 We present a novel scheme for the appearance of Stochastic Resonance when the dynamics of a Brownian particle takes place in a confined medium. The presence of uneven boundaries, giving rise to an entropic contribution to the potential, may upon application of a periodic driving force result in an increase of the spectral amplification at an optimum ...

Stochastic resonance in electrical circuits. I. Conventional stochastic resonance [PDF]
IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 1999 For pt.I see ibid., vol.46, no.9, pp.1205-14 (1999). Stochastic resonance (SR), in which a periodic signal in a nonlinear system can be amplified by added noise, is discussed. The application of circuit modeling techniques to the conventional form of SR, which occurs in static bistable potentials, was considered in a companion paper.

Gray Image Denoising Based on Array Stochastic Resonance and Improved Whale Optimization Algorithm
Applied Sciences, 2022 Aiming at the poor effect of traditional denoising algorithms on image enhancement with strong noise, an image denoising algorithm based on improved whale optimization algorithm and parameter adaptive array stochastic resonance is proposed in the paper ...

Geometric Stochastic Resonance [PDF]
Physical Review Letters, 2010 A Brownian particle moving across a porous membrane subject to an oscillating force exhibits stochastic resonance with properties which strongly depend on the geometry of the confining cavities on the two sides of the membrane. Such a manifestation of stochastic resonance requires neither energetic nor entropic barriers, and can thus be regarded as a ...
