Solitary wave structures for the stochastic Nizhnik–Novikov–Veselov system via modified generalized rational exponential function method

Results in Physics, 2023
In this article, a significant stochastic Nizhnik–Novikov–Veselov (SNNV) system with truncated M-fractional derivative (TMD) is investigated. This mathematical model is considered an isotropic Lax extension of the one-dimensional Kortewegde Vries ...

Global Ionospheric Scintillation Estimation Based on Phase Screen Modeling From One‐Dimensional Satellite Data

Space Weather, Volume 23, Issue 1, January 2025.
Abstract Ionospheric scintillations, which usually manifest as sudden, rapid fluctuations in radio wave signal phase and amplitude, challenge the reliability of satellite communication and navigation. Based on the single phase screen assumption, this study uses the one‐dimensional (1D) in‐situ plasma density data of ESA's Swarm constellation data to ...

TIE‐GCM ROPE ‐ Dimensionality Reduction: Part I

Space Weather, Volume 23, Issue 1, January 2025.
Abstract Physics‐based models of the ionosphere‐thermosphere system have been touted as the next big thing in the context of drag modeling and space operations for decades. However, the computational complexity of such models have primarily kept them being used operationally.

Fluctuational electrodynamics for nonlinear media [PDF]

EPL 115, 41002 (2016), 2016
We develop fluctuational electrodynamics for media with nonlinear optical response. In a perturbative manner, we amend the stochastic Helmholtz equation to describe fluctuations in a nonlinear setting, in agreement with the fluctuation dissipation theorem, and identify the local (Rytov) current fluctuations.

Inflation of universe due to nonlinear electrodynamics [PDF]

International Journal of Modern Physics A, Vol. 32 (2017) 1750071, 2017
A model of nonlinear electrodynamics with a dimensional parameter $\beta$ is considered. Electromagnetic fields are the source of the gravitation field and inflation of the universe. We imply that the universe is filled by stochastic magnetic fields. It is demonstrated that after the universe inflation the universe decelerates approaching the Minkowski

Economic and Sensitivity Analyses of Controllable Queues With Customer Feedback and Impatience Using Markovian Modeling

Journal of Mathematics, Volume 2025, Issue 1, 2025.
The present investigation proposes a unique strategy for the establishment of a controllable queuing system using Markovian modeling. In comparison to conventional models, this approach combines customer impatience, feedback procedure, and working vacation into the statistical modeling of queues in a novel manner.
