Magnetic Structure of the High‐TN Antiferromagnet La0.5Sr3.5Fe3O7.5F2.6: A Temperature‐Dependent Mößbauer Spectroscopy and Neutron Diffraction Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.

A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

High Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Bridging the small‐angle X‐ray scattering–X‐ray diffraction gap in disordered layered materials: the CLADIFFMOD unified framework

Journal of Applied Crystallography, EarlyView.
A unified multi‐scale framework is proposed for the consistent analysis of small‐angle X‐ray scattering (SAXS) and X‐ray diffraction (XRD) in disordered clay minerals, combining morphology, stacking and turbostratic contributions within a single formalism.

Noise and Drift Models for Protonic ECRAM and Their Impact on Analog In‐Memory Computing

Advanced Computing, Volume 1, Issue 1, December 2026.
Read noise and conductance drift of protonic electrochemical random‐access memory (ECRAM) are characterized and described using physics‐informed device models. These models connect proton transport and measured current fluctuations to analog in‐memory computing (AIMC) performance.

Proper affine deformations of positive representations

Journal of Topology, Volume 19, Issue 4, December 2026.
Abstract We define, for every positive Anosov representation of a nonabelian free group into SO(2n,2n−1)$\mathrm{SO}(2n,2n-1)$, a family of R4n−1$\mathbb {R}^{4n-1}$‐valued cocycles which induce proper affine actions on R4n−1$\mathbb {R}^{4n-1}$. We construct fundamental domains in R4n−1$\mathbb {R}^{4n-1}$ bounded by generalized crooked planes for ...
