Managers' Decisions About Informal Accommodation Requests by Employees With and Without Disabilities
Human Resource Management, Volume 65, Issue 3, Page 823-846, May/June 2026.ABSTRACT Although formal accommodations are required by law across many jurisdictions, many employees seek informal adjustments to their work conditions. These individualized work arrangements are not rooted in legal compliance but are instead provided at managers' discretion.

A parallel algorithm for generating Pareto‐optimal radiosurgery treatment plans
Medical Physics, Volume 53, Issue 5, May 2026.Abstract Background Using inverse planning tools to create radiosurgery treatment plans is an iterative process, where clinical trade‐offs are explored by changing the relative importance given to different objectives and rerunning the optimizer until a desirable plan is found.

Coulomb branch operators and mirror symmetry in three dimensions
Journal of High Energy Physics, 2018 We develop new techniques for computing exact correlation functions of a class of local operators, including certain monopole operators, in three-dimensional N=4 $$ \mathcal{N}=4 $$ abelian gauge theories that have superconformal infrared limits.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.Abstract This study proposes a new scheme combining ensemble blending and dual‐localization of ensemble error covariance in an ensemble‐variational (EnVar) framework to better account for both the multi‐scale characteristics of the background and background error covariance for high‐resolution data assimilation and forecasting.

Geophysical Prospecting, Volume 74, Issue 4, May 2026.ABSTRACT The electrical resistivity tomography (ERT) is a geophysical method commonly used in mining exploration to reconstruct the subsurface resistivity. The associated inverse problem is typically addressed using deterministic approaches that minimize an objective function and guarantee fast convergence.

A note on the formulas for the Drazin inverse of the sum of two matrices
Open Mathematics, 2019 In this paper we derive the formula of (P + Q)D under the conditions Q(P + Q)P(P + Q) = 0, P(P + Q)P(P + Q) = 0 and QPQ2 = 0. Then, a corollary is given which satisfies the conditions (P + Q)P(P + Q) = 0 and QPQ2 = 0. Meanwhile, we show that the additive

Littlewood, Paley and almost‐orthogonality: a theory well ahead of its time
Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.Abstract The classic paper by Littlewood and Paley [J. Lond. Math. Soc. (1), 6 (1931), 230–233] marked the birth of Littlewood–Paley theory. We discuss this paper and its impact from a historical perspective, include an outline of the results in the paper and their subsequent significance in relation to developments over the last century, and set them ...

Vertex operator algebras, Higgs branches, and modular differential equations
Journal of High Energy Physics, 2018 Every four-dimensional N=2 $$ \mathcal{N}=2 $$ superconformal field theory comes equipped with an intricate algebraic invariant, the associated vertex operator algebra.

Entrywise transforms preserving matrix positivity and nonpositivity
Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.Abstract We characterize real and complex functions which, when applied entrywise to square matrices, yield a positive definite matrix if and only if the original matrix is positive definite. We refer to these transformations as sign preservers. Compared to the classical work on entrywise preservers by Schoenberg and others, we completely resolve this ...

Line defect Schur indices, Verlinde algebras and U(1) r fixed points
Journal of High Energy Physics, 2017 Given an N=2 $$ \mathcal{N}=2 $$ superconformal field theory, we reconsider the Schur index ℐ L (q) in the presence of a half line defect L. Recently Cordova-Gaiotto-Shao found that ℐ L (q) admits an expansion in terms of characters of the chiral algebra
