Accelerated Brain Atrophy in Epilepsy: A Prospective Population‐Based Study

Annals of Neurology, Volume 100, Issue 5, Page 1028-1038, November 2026.
Objective Previous longitudinal neuroimaging studies suggest that epilepsy is a progressive disorder. To date, these findings have relied largely on populations from tertiary centers, resulting in ascertainment bias, as severely affected individuals are more likely to be rescanned.

Beyond Directions: Symmetry‐Aware Rotation Sets for Triaxial Diffusion Encoding by Geometric Filter Optimization

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2489-2504, November 2026.
ABSTRACT Purpose To improve the accuracy of diffusion‐weighted powder average signals for diffusion encoding with arbitrary b‐tensors. Methods We identify an intrinsic dihedral (D2) symmetry of diffusion signals for arbitrary diffusion encoding, which defines their natural signal space (a quotient of 3D rotations). Based on this, we propose a method to

Tectonic Re‐Organization and Onset of South Caspian Escape Tectonics at 1.8–2.4 Ma

Basin Research, Volume 38, Issue 6, November‐December 2026.
We show that the presently active tectonics of the South Caspian began relatively recently, likely in the range 1.8–2.4 Myr and replacing an older tectonic configuration ending in the Miocene at ~6 Ma. The various short‐lived stages in the destruction of the South Caspian have potential for insight into the late stages of basin closure and the ...

The Haagerup property is not invariant under quasi‐isometry

Bulletin of the London Mathematical Society, Volume 58, Issue 11, November 2026.
Abstract Using the work of Cornulier–Valette and Whyte (see Appendix A for the latter), we show that neither the Haagerup property nor weak amenability is invariant under quasi‐isometry of finitely generated groups. Appendix B shows, using the same examples, that the same holds for vanishing of the equivariant Lp$L^p$‐compression.

Foliation of null cones by surfaces of constant spacetime mean curvature near MOTS

Journal of the London Mathematical Society, Volume 114, Issue 5, November 2026.
Abstract Marginally outer trapped surfaces (MOTS) in spacetimes are well‐known to indicate the existence of black holes. Using flow techniques, we prove that a neighbourhood of a stable MOTS in a null cone may be foliated by hypersurfaces of constant spacetime mean curvature.
