A note on local formulae for the parity of Selmer ranks
Bulletin of the London Mathematical Society, EarlyView.Abstract In this note, we provide evidence for a certain ‘twisted’ version of the parity conjecture for Jacobians, introduced in prior work of Dokchitser, Green, Konstantinou and the author. To do this, we use arithmetic duality theorems for abelian varieties to study the determinant of certain endomorphisms acting on p∞$p^\infty$‐Selmer groups.

Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.Abstract In subwavelength physics, a challenging problem is to characterise the spectral properties of finite systems of subwavelength resonators. In particular, it is important to identify localised modes as well as bandgaps and associated mobility edges.

Explicit height estimates for CM curves of genus 2
Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.Abstract In this paper, we make explicit the constants of Habegger and Pazuki's work from 2017 on bounding the discriminant of cyclic Galois CM fields corresponding to genus 2 curves with CM and potentially good reduction outside a predefined set of primes. We also simplify some of the arguments.

Robust multi‐coil MRI reconstruction via self‐supervised denoising
Magnetic Resonance in Medicine, Volume 94, Issue 5, Page 1859-1877, November 2025.Abstract Purpose To examine the effect of incorporating self‐supervised denoising as a pre‐processing step for training deep learning (DL) based reconstruction methods on data corrupted by Gaussian noise. K‐space data employed for training are typically multi‐coil and inherently noisy.

A note on the magnetic Steklov operator on functions
Mathematika, Volume 71, Issue 4, October 2025.Abstract We consider the magnetic Steklov eigenvalue problem on compact Riemannian manifolds with boundary for generic magnetic potentials and establish various results concerning the spectrum. We provide equivalent characterizations of magnetic Steklov operators which are unitarily equivalent to the classical Steklov operator and study bounds for the ...

Higher order constraints for the ( $$\beta $$ β -deformed) Hermitian matrix models
European Physical Journal C: Particles and FieldsWe construct the ( $$\beta $$ β -deformed) higher order total derivative operators and analyze their remarkable properties. In terms of these operators, we derive the higher order constraints for the ( $$\beta $$ β -deformed) Hermitian matrix models.

Two‐Way Relaying for Orbital Angular Momentum LOS Transmission
International Journal of Communication Systems, Volume 38, Issue 13, 10 September 2025.This paper investigates two‐way relaying (TWR) for orbital angular momentum (OAM)‐based line‐of‐sight (LOS) transmission. Low‐complexity near‐ML detectors are proposed for OAM mode division multiplexing and index modulation. Theoretical analysis and simulations confirm that TWR significantly improves bit error performance and spectral efficiency over ...
