On the expectation of the local time of the fractional Brownian motion
In this paper, we prove some new formulas of the expectations of LBH and LBH the local time and the weighted local time of BH the fractional Brownian motion with Hurst parameter H.

Weak solutions and optimal controls of stochastic fractional reaction-diffusion systems
The aim of this paper is to investigate a class of nonlinear stochastic reaction-diffusion systems involving fractional Laplacian in a bounded domain. First, the existence and uniqueness of weak solutions are proved by using Galërkin’s method.

CALCULATION OF WEIGHT COEFFICIENTS IN CONTINUOUS PARTICLE FILTER
This article shows the relationship between filters based on modeling of the random process paths with terminating and branching and a continuous particle filter that are related to sequential Monte Carlo methods.

We introduce the conformable fractional (CF) noninstantaneous impulsive stochastic evolution equations with fractional Brownian motion (fBm) and Poisson jumps. The approximate controllability for the considered problem was investigated.

Time after time – circadian clocks through the lens of oscillator theory
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
