Numerical Solutions Of The Nonlocal Problems For The Diffusion Partial Differential Equations
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 In this work, we use the explicit and the implicit finite-difference methods to solve the nonlocal problem that consists of the diffusion equations together with nonlocal conditions.

, 2009 We consider a control- and state-constrained optimal control problem governed by a semilinear elliptic equation with nonlocal interface conditions. These conditions occur during the modeling of diffuse-gray conductive-radiative heat transfer.

Land Degradation &Development, EarlyView.ABSTRACT Rainfall‐induced physical crusting is associated with degradation of near‐surface soil structure, but its pore‐scale structural and mechanical evolution during drying remains poorly resolved. We combined time‐resolved X‐ray computed tomography (XCT), digital volume correlation (DVC), and surface‐aligned stratification to track pore ...

Quantization of Polaritons Confined in Dielectric Structures
Laser &Photonics Reviews, EarlyView.This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Laser &Photonics Reviews, EarlyView.A metasurface‐enabled full‐Stokes polarimeter is integrated with phase‐interrogated surface plasmon resonance microscopy to enable single‐shot recovery of intensity and differential phase. The non‐interferometric platform supports quantitative refractive‐index and thickness mapping, wavelength‐resolved sensing, and dynamic multi‐channel monitoring ...

Laser &Photonics Reviews, EarlyView.Nonlocal leaky mode metasurfaces reconstruct multiplexed holograms directly from unfiltered thermal light. High‐Q leaky guided modes compress broadband halogen emission into narrowband channels, enhancing temporal coherence a hundredfold, while a single nanohole array encodes independent images addressed by mode, angle, and polarization, establishing ...

Karpatsʹkì Matematičnì Publìkacìï, 2019 In this article we investigate a problem with nonlocal boundary conditions which are multipoint perturbations of mixed boundary conditions in the unit square $G$ using the Fourier method. The properties of a generalized transformation operator $R: L_2(G)

Purely Coclosed G2‐Structures on Nilmanifolds—II
Mathematische Nachrichten, EarlyView.ABSTRACT This paper completes the classification of seven‐dimensional nilpotent Lie groups endowed with a left‐invariant purely coclosed G2$\text{G}_2$‐structure, initiated in Bazzoni et al. [Mathematische Nachrichten 296 no. 6 (2023): 2236–2257], the authors provided the classification of decomposable seven‐dimensional nilpotent Lie groups and of the ...

A Class of Nonlocal Coupled Semilinear Parabolic System with Nonlocal Boundaries
The Scientific World Journal, 2014 We investigate the positive solutions of the semilinear parabolic system with coupled nonlinear nonlocal sources subject to weighted nonlocal Dirichlet boundary conditions. The blow-up and global existence criteria are obtained.
