This current research is about some new optical solitons to the time-fractional integrable generalized (2+1)-dimensional nonlinear Schrödinger (NLS) system with novel truncated M-fractional derivative. The obtained results may be used in the descrip

We study all the ways that a given convex body in $d$ dimensions can break into countably many pieces that move away from each other rigidly at constant velocity, with no rotation or shearing. The initial velocity field is locally constant, but may b

In this paper, we study the generation and propagation of oscillatory solutions observed in the widely used Lorenz 96 (L96) systems. First, period-two oscillations between adjacent grid points are found in the leading-order expansions of the discrete

Linear response theory is a fundamental framework studying the macroscopic response of a physical system to an external perturbation. This paper focuses on the rigorous mathematical justification of linear response theory for Langevin dynamics. We gi

In this paper, we propose a drift-diffusion process on the probability simplex to study stochastic fluctuations in probability spaces. We construct a counting process for linear detailed balanced chemical reactions with finite species such that its t

The Random Batch Method (RBM) proposed in [Jin et al. J Comput Phys, 2020] is an efficient algorithm for simulating interacting particle systems. In this paper, we investigate the Random Batch Method with replacement (RBM-r), which is the same as the

We present a new strategy for filtering high-dimensional multiscale systems characterized by high-order non-Gaussian statistics using observations from leading-order moments. A closed stochastic-statistical modeling framework suitable for systematic

In this paper, we consider a Hele-Shaw model that describes tumor growth subject to nutrient supply. This model was recently studied in \cite{feng2022tumor} via asymptotic analysis. Our contributions are twofold: Firstly, we provide a rigorous deriva

The safety situation in the construction industry across the world has been complicated for a long time, and the high incidence of accidents poses great challenges to this situation. Research on occupational safety and health indicates that people ar

The corrosion behavior of X65 steel in the CO2/oil/water environment of gathering pipeline was investigated by mass loss, X-ray powder diffraction (XRD), scanning electron microscopy with X-ray microanalysis (SEM-EDS), and electrochemical analysis th
