Dynamic boundary conditions with noise for an energy balance model coupled to geophysical flows

Mathematische Nachrichten, EarlyView.
Abstract This paper investigates a Sellers‐type energy balance model coupled to the primitive equations by a dynamic boundary condition with and without noise on the boundary. It is shown that this system is globally strongly well‐posed both in the deterministic setting for arbitrary large data in W2(1−1/p),p$W^{2(1-\nicefrac {1}{p}),p}$ for p∈[2,∞)$p \

Fluid to Solid Transition in Colloidal Suspensions of Thermo Responsive Core–Shell Soft Particles Interacting through Multi‐Hertzian Pair‐Potential: A Monte Carlo Study

Macromolecular Theory and Simulations, EarlyView.
Temperature‐driven deswelling of PNIPAM microgels transforms an ordered suspension into a fluid‐like state. The study links changes in radial distribution and diffusion of soft colloids (PNIPAM) adapt their structure and dynamics under thermal stimuli. ABSTRACT Maxime J. Bergman et al.

Enhanced Thermal and Mass Diffusion in Maxwell Nanofluid: A Fractional Brownian Motion Model

Fractal and Fractional
This paper introduces fractional Brownian motion into the study of Maxwell nanofluids over a stretching surface. Nonlinear coupled spatial fractional-order energy and mass equations are established and solved numerically by the finite difference method ...

Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...

Results on the Supremum of Fractional Brownian Motion

, 2009
We show that the distribution of the square of the supremum of reflected fractional Brownian motion up to time a, with Hurst parameter-H greater than 1/2, is related to the distribution of its hitting time to level 1, using the self similarity property of fractional Brownian motion.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Impact of Al3+ Concentration on Montmorillonite Sedimentation: Insights Into Particle Size Behavior

ChemistryOpen, EarlyView.
The current research essentially focuses on the coagulation and sedimentation characteristics of particles with two distinct particle‐size compositions. The DLVO theory confirms that under the influence of aluminum ions, the coarse and fine particle sampleS of montmorillonite essentially possess the effect of eliminating or weakening the “barrier ...
