ON \(\Lambda\)-CONVERGENCE ALMOST EVERYWHERE OF MULTIPLE TRIGONOMETRIC FOURIER SERIES
Ural Mathematical Journal, 2017 We consider one type of convergence of multiple trigonometric Fourier series intermediate between the convergence over cubes and the \(\lambda \)-convergence for \(\lambda >1\).

Addiction, Volume 121, Issue 10, Page 2822-2832, October 2026.Abstract Background and aims Data on the presence of new psychoactive substances (NPS) mainly originate from drug‐checking, law enforcement and wastewater analysis sources, while data on NPS poisonings are scarce. In Europe, the documented incidence rate of NPS poisonings is highest in the Netherlands.

Journal of Computational Chemistry, Volume 47, Issue 24, September 15, 2026.DL_FFLUX, which houses the quantum‐topological machine‐learning potential FFLUX, is refactored and computationally optimized through software‐level code optimization and prediction caching. The new implementation accelerates molecular dynamics simulations 93‐fold for the largest models while preserving accuracy.

On Divergence of Fourier Series by Some Methods of Summability
Journal of Function Spaces and Applications, 2012 A new summability method of series is introduced and studied. The particular cases of this method are, for example, variable-order Cesaro and Riesz methods. Applications to divergence problem of Fourier series are given.

Sundman‐Like Transformations and the NRT Nonlinear Schrödinger Equation
Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14791-14810, 15 September 2026.ABSTRACT We present a new generalization of the well‐known power‐type Sundman transformation, involving not only powers of the function but also of its derivative, along with its inverse. Our aim is to explore the use of such transformations in the derivation of solutions of ordinary differential equations and in the study of their properties.

ce/papers, Volume 9, Issue 2-3, Page 791-796, September 2026.Abstract This paper proposes a shear‐deformable Generalized Beam Theory (GBT)–Ritz formulation for efficient buckling analysis of thin‐walled composite beams with unsymmetric layups, where extension–bending–twist coupling renders classical beam models inadequate. GBT is used to generate physically interpretable cross‐sectional deformation modes (global,

Solutions of two open problems on inequalities involving trigonometric and hyperbolic functions
CuboIn 2019, Bagul et al. posed two open problems dealing with inequalities involving trigonometric and hyperbolic functions and an adjustable parameter. This article is an attempt to solve these open problems.

Communications on Pure and Applied Mathematics, Volume 79, Issue 9, Page 2107-2157, September 2026.ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...
