Prevalence and Spectrum of Congenital Heart Disease in Individuals With Distal Chromosome 22q11.22–23 Deletions

open access: yesClinical Genetics, Volume 109, Issue 5, Page 859-868, May 2026.
The frequency and severity of congenital heart disease vary extensively in individuals with 22q11.22–23 distal deletions. Reduced gene dosage particularly within the low copy repeat (LCR22) D–E region including MAPK1 and HIC2 conveys risk for these defects.

Meeting Students Where They Are: A Field Experiment of Classroom Interventions for Voter Turnout Among College Students

open access: yesSocial Science Quarterly, Volume 107, Issue 3, May 2026.
ABSTRACT Objective The goal of this project is to test the effectiveness of various get‐out‐the‐vote (GOTV) strategies on college students’ propensity to vote in state and local elections. Methods We conduct a field experiment testing different types of GOTV activities at a large public university during a low salience local election.

Littlewood, Paley and almost‐orthogonality: a theory well ahead of its time

open access: yesJournal 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 ...

Lorentzian homogeneous structures with indecomposable holonomy

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract For a Lorentzian homogeneous space, we study how algebraic conditions on the isotropy group affect the geometry and curvature of the homogeneous space. More specifically, we prove that a Lorentzian locally homogeneous space is locally isometric to a plane wave if it admits an Ambrose–Singer connection with indecomposable, non‐irreducible ...

Robust Inverse Material Design With Physical Guarantees Using the Voigt‐Reuss Net

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT We apply the Voigt‐Reuss net, a spectrally normalized neural surrogate introduced in [38], for forward and inverse mechanical homogenization with a key guarantee that all predicted effective stiffness tensors satisfy Voigt‐Reuss bounds in the Löwner sense during training, inference, and gradient‐driven optimization.
