Information and Telecommunication Sciences, 2016 Background. Application of deterministic chaos oscillators in telecommunication systems requires knowledge about their dynamical properties. Mathematical models and phase portraits of such generators are well known.

Stochastic Resonance in a Multistable System Driven by Gaussian Noise
Discrete Dynamics in Nature and Society, 2016 Stochastic resonance (SR) is investigated in a multistable system driven by Gaussian white noise. Using adiabatic elimination theory and three-state theory, the signal-to-noise ratio (SNR) is derived.

Resonance fluorescence of noisy systems
New Journal of Physics, 2023 Light scattering from resonantly or nearly resonantly excited systems, known as resonance fluorescence (RF), has been gaining importance as a versatile tool for investigating quantum states of matter and readout of quantum information, recently including

Fractal and Fractional, 2023 We consider in this study the (3+1)-dimensional stochastic potential Yu–Toda–Sasa–Fukuyama with conformable derivative (SPYTSFE-CD) forced by white noise.

The asymptotics of stochastically perturbed reaction-diffusion equations and front propagation
Comptes Rendus. Mathématique, 2020 We study the asymptotics of Allen–Cahn-type bistable reaction-diffusion equations which are additively perturbed by a stochastic forcing (time white noise).

ERRATUM: White-Noise Representations in Stochastic Realization Theory [PDF]
SIAM Journal on Control and Optimization, 2010 A result of [V. S. Borkar, SIAM J. Control Optim. 31 (1993), pp. 1093–1102] concerning characterization of ergodic processes in terms of purely nondeterministic processes is corrected.

Random Weighting-Based Nonlinear Gaussian Filtering
IEEE Access, 2020 The Gaussian filtering is a commonly used method for nonlinear system state estimation. However, this method requires both system process noise and measurement noise to be white noise sequences with known statistical characteristics.

Relaxation times in a bistable system with parametric, white noise: Theory and experiment [PDF]
Physical Review A, 1985 We consider the effects of external, multiplicative white noise on the relaxation time of a general representation of a bistable system from the points of view provided by two, quite different, theoretical approaches: the classical Stratonovich decoupling of correlations and the new method due to Jung and Risken.

Random Matrix Theory Predictions of Dominant Mode Rejection Beamformer Performance
IEEE Open Journal of Signal Processing, 2022 Adaptive beamformers use a sensor covariance matrix estimated from data snapshots to mitigate directional interference and attenuate uncorrelated noise.

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
