Boundary condition of the volume potential for an elliptic-parabolic equation with a scalar parameter

open access: yesElectronic Journal of Differential Equations, 2018
Using the descent method for the fundamental solution of the heat equation with a scalar parameter, we find the fundamental solution of the multidimensional Helmholtz equation in an explicit form.

Existence of global solutions to nonlinear mixed Volterra-Fredholm integrodifferential equations with nonlocal conditions

open access: yesElectronic Journal of Differential Equations, 2009
In this paper, we investigate the existence of global solutions to first-order initial-value problems, with nonlocal condition for nonlinear mixed Volterra-Fredholm integrodifferential equations in Banach spaces. The technique used in our analysis is

Interplay Between Bound State in the Continuum and the Generalized Kerker Effect in Plasmonic Metasurfaces

open access: yesAdvanced Photonics Research, Volume 7, Issue 8, August 2026.
A plasmonic metasurface comprising gold cylinders of tailored dimensions exhibits simultaneously the generalized Kerker effect and a bound state in the continuum, allowing for a detailed study of the subtle interplay between these phenomena. The numerical simulation results are in good agreement with experimental measurements, and the underlying ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Fast Calculation for the Flow and Heat Transfer of Tempered Fractional Maxwell Viscoelastic Fluid

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 8, Page 969-979, August 2026.
This study develops a tempered fractional Maxwell model to simulate unsteady thermal flow in viscoelastic fluids, capturing key rheological behaviors. A fast SOE‐based algorithm is proposed to improve the computational efficiency of the numerical scheme. Results reveal how key parameters influence fluid motion and heat transfer, demonstrating the model'

Damping amyloid‐associated conformational fluctuations in a protein by an engineered diselenide bridge

open access: yesProtein Science, Volume 35, Issue 8, August 2026.
Abstract Polypeptide cross‐β assembly, characteristic of diverse proteotoxic diseases, defines a general thermodynamic ground state and limits the shelf lives of peptide‐ and protein therapeutics. A model is provided by insulin. Although the hormone contains a predominance of α‐helix, its fibrils exhibit cross‐β reorganization.

Error Growth Characterization Associated With Lateral Boundary Conditions in Idealized Moist Baroclinic Wave Simulations

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract This study investigates numerical error growth mechanisms associated with lateral boundary conditions (LBCs) and their sensitivity to update frequency within a “Big‐Brother” framework. Using an idealized moist WRF baroclinic wave simulation, a high‐resolution reference is compared against three nested configurations: traditional one‐way 6‐hr ...
