Statistical and Numerical Analysis of Conjugate Heat and Momentum Transfer in an Open Cavity With a Thick Wall Using Cu–Water Nanofluid

Engineering Reports, Volume 8, Issue 3, March 2026.
Considered physical model and effect of Nuav(τ = 0.1) for Re and ϕ at τ = 0.1. ABSTRACT Although open cavity configurations are common in modern electronic and solar applications, limited attention has been given to thick‐walled hollow cavity designs, particularly in the context of comprehensive sensitivity analysis.

Convolution of probabilities constant in a subgroup and outside a subgroup

Visnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika
Let be $P$ the probability on a finite group $G$, i.e. the function $P\left(g\right)$ takes non-negative values and $\sum _{g}P\left(g\right) =1$ $\left(g\in G\right)$.

Finite Element Analysis and ANN Validation of Mixed Convection Nanofluid Flow in a Star‐Shaped Corrugated Cavity With Multiple Heated Baffles

Engineering Reports, Volume 8, Issue 3, March 2026.
This study carefully examines the mixed convection heat transport properties of a water–Al2O3 nanofluid inside a corrugated chamber with heated baffles in the shape of a star. The effects of different Rayleigh numbers, nanoparticle volume fractions, and baffle placement are carefully evaluated, and the cavity is subjected to buoyancy forces. The finite

Homomorphisms of convolution algebras

Journal of Functional Analysis, 2011
\textit{P. J.~Cohen} [``On homomorphisms of group algebras'', Am. J. Math. 82, 213--226 (1960; Zbl 0099.25601)] characterised all homomorphisms \(\phi: L^1(G)\to M(H)\) between the group and measure algebras of locally compact abelian groups \(G\) and \(H\).

Amenability for discrete convolution semigroup algebras.

MATHEMATICA SCANDINAVICA, 1990
Summary: For any semigroup \(S\) we show that if the convolution algebra \(\ell^ 1(S,\omega)\) is amenable for some weight \(\omega\) then \(S\) is a regular semigroup with a finite number of idempotents: in particular, for the case of an inverse semigroup \(S\), we have \(\ell^ 1(S)\) amenable if and only if \(S\) has a finite number of idempotents ...

Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Phase‐Space Synchronization Driven by Moon‐Magnetosphere Coupling in Gas Giants

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present a new theoretical framework to describe the rapid and spatially localized loss of energetic particles in planetary radiation belts, focusing on interactions between gas giant magnetospheres and their moons. Observations show that flux depletions—known as microsignatures—often refill on timescales comparable to a single drift period,

Poroelastic Bulk Controls on Shear Localization in Fault Gouge During Earthquake Rupture: Insights From a Hybrid Numerical Framework

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Seismic ruptures that extend over kilometers along faults originate in shear zones only millimeters thick. We present a hybrid numerical framework coupling the spectral boundary integral method (SBIM) for the poroelastic bulk with a staggered‐grid finite difference method (FDM) for the fault gouge.

A Wave Tank Study on Turbulent Transport of a Passive Tracer Above Gravelly Sand Beds

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Exchange processes at the seabed interface have a non‐negligible impact on biogeochemical processes of the sea. Acknowledging this impact on the input of nutrients from the seabed into the water column further entails properly assessing the transport and mixing of these nutrients within the water column.
