On Gaussian–Bessel Integrals in Diffusion‐Based Wind‐Turbine Wake Models
Wind Energy, Volume 29, Issue 11, November 2026.ABSTRACT The diffusion wake model provides an analytical description of turbine‐wake evolution from a top‐hat profile in the near wake to a self‐similar Gaussian profile in the far wake. The main formulation of the model involves an integral containing the product of linear, Gaussian, and modified Bessel‐function terms. This integral is closely related

Inverse spectral analysis for singular differential operators with matrix coefficients
Electronic Journal of Differential Equations, 2006 Let $L_alpha$ be the Bessel operator with matrix coefficients defined on $(0,infty)$ by $$ L_alpha U(t) = U''(t)+ {I/4-alpha^2over t^2}U(t), $$ where $alpha$ is a fixed diagonal matrix.

Selector form of Weaver's conjecture and frame sparsification
Proceedings of the London Mathematical Society, Volume 133, Issue 5, November 2026.Abstract We show an extension of a probabilistic result of Marcus, Spielman, and Srivastava, which resolved the Kadison–Singer problem, to block diagonal positive semidefinite random matrices. We use this result to show several selector results, which generalize their partition counterparts.

Dielectric Nanoparticle Dimers on a Mirror for Enhanced Photoluminescence of Quantum Dots
Nanophotonics, Volume 15, Issue 20, 27 October 2026.Hybrid metal–dielectric nanoantennas based on nanoparticle‐on‐mirror architectures are proposed to enhance quantum dot photoluminescence. Silicon nanocylinder dimers on aluminum substrates enable simultaneous excitation enhancement and directional emission through strong light–matter interactions.

A Сauchy problem for a third-order pseudo-parabolic equation with the Bessel operator
This article investigates the Cauchy problem for a third-order pseudo-parabolic equation with a Bessel operator. Using the Erdelyi-Kober operator transformation, the Riemann’s function for this equation is constructed, which is expressed through the ...
