Nonlocal Mixed Systems With Neumann Boundary Conditions

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 13, Page 12632-12643, September 2025.
ABSTRACT We prove well posedness and stability in L1$$ {\mathbf{L}}^1 $$ for a class of mixed hyperbolic–parabolic nonlinear and nonlocal equations in a bounded domain with no flow along the boundary. While the treatment of boundary conditions for the hyperbolic equation is standard, the extension to L1$$ {\mathbf{L}}^1 $$ of classical ...

Asymptotic Analysis of Stokes Flow Through a Filter

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 13, Page 12913-12934, September 2025.
ABSTRACT This paper investigates the Stokes flow through a thin porous layer composed of a rigid, thin, periodic, and closely packed array of parallel long rods with a noncircular, anisotropic cross‐section in the shape of a slot. This shape allows for the construction of a thicker permeable filter than what is known as the Brinkman critical size.

Electrical properties based B1+ prediction for electrical properties tomography reconstruction evaluation

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 3, Page 1269-1283, September 2025.
Abstract Purpose In MR electrical properties tomography (EPT), conductivity and permittivity are reconstructed from MR measurements. However, depending on the reconstruction method, reconstructed electrical properties (EPs) show large variability in vivo, reducing confidence in the reconstructed values for clinical application in practice.

Homogeneous Multigrid for Hybrid Discretizations: Application to HHO Methods

open access: yesNumerical Methods for Partial Differential Equations, Volume 41, Issue 5, September 2025.
ABSTRACT We prove the uniform convergence of the geometric multigrid V‐cycle for hybrid high‐order (HHO) and other discontinuous skeletal methods. Our results generalize previously established results for HDG methods, and our multigrid method uses standard smoothers and local solvers that are bounded, convergent, and consistent.

Trends and Topics Evolution in Research on Giftedness in Education: A Bibliometric Analysis

open access: yesPsychology in the Schools, Volume 62, Issue 9, Page 3403-3413, September 2025.
ABSTRACT The article explores the evolution of research on giftedness and high ability through a bibliometric analysis. It highlights challenges in identifying gifted individuals, who represent approximately 6.5% of students, although biased instruments and discriminatory selection practices may affect the identification of high skilled students.
