Stochastic Particle Creation: From the Dynamical Casimir Effect to Cosmology.

We compare the stochastic particle creation with that of its deterministic counterpart. We go beyond the initial results using a stochastic version of the multiple scale analysis that takes into account stochastic parametric resonance. The equations are generally similar to those that describe the stochastic particle creation in a cosmological context, which we refer to in the single-mode approximation, which we redefine using multiple scale analysis.

Effect of Music Tempo on Pattern Reversal Visual Evoked Potential in Young Adults-Multisensory Stochastic Resonance: A Pilot Study.

A phenomenon in which an intermediate degree of noise increases the response of a weak input signal. We're guessing that soon enough, it will be possible to produce and produce new products that support multisensory SR in the audio-visual format for human sensorimotor enhancement and rehabilitation goals. This review was the first in which the auditory noise was used in the form of a song of different tempos and their amplitude and latency of P100 PRVEP. If the different tempos song changes the PRVEP, it may have an effect on the PRVEP. This review was based on 57 healthy volunteers in AIIMS Bhopal. Vision correction, especially in patients with low amplitude PRVEP, can be aided by music therapy. A more appropriate number of samples for further research in multisensory SR with visual evoked potentials are required.

Phenomenological bifurcation in a generally stochastic population model with Allee effect.

We obtain the model's static probability distribution with the Fokker-Planck equation, and we find that the SPD model's form changes from one structure to another when the noise level rises to a new threshold, i. e. , the P-bifurcation occurs. This paper seeks to investigate noise-induced phenomenological bifurcation in a general population model with Allee's effect owing to similar additive and multiplicative white noises. When the noise level rises to a new level, i. e. , P-bifurcation occurs, the SPD shapes change from one structure to another.
