Computing the bridge length: the key ingredient in a continuous isometry classification of periodic point sets

Acta Crystallographica Section A, Volume 81, Issue 6, Page 427-437, November 2025.
We describe an efficient algorithm to compute the bridge length estimating the size of a complete isoset invariant, which classifies all periodic point sets under Euclidean motion.The fundamental model of any periodic crystal is a periodic set of points at all atomic centres.

Stratospheric Injection Lifetimes

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract Material injected to the stratosphere by volcanoes and pyrocumulonimbus clouds (pyroCbs) is observed to have different lifetimes depending on the altitude, latitude, season of the injection, and removal processes. We adopt a framework that describes the stratospheric lifetime of injected material as the sum of lag and decay timescales and ...

Charge Transport and Carrier Polarity Tuning by Electrolyte Gating in Nickel Benzenehexathiol Coordination Nanosheets

Advanced Materials, Volume 37, Issue 32, August 14, 2025.
This work reveals that charge transport in nickel benzenehexathiol coordination nanosheets is governed by variable‐range hopping reflecting structural disorder. Electrolyte gating induces a switch in dominant carrier polarity from p‐type to n‐type and leads to an improvement in thermoelectric performance.

Path Integral Spin Dynamics for Quantum Paramagnets

Advanced Physics Research, Volume 4, Issue 8, August 2025.
The study has developed a path integral method, which is a classical approach, combined with atomistic spin dynamics simulations to calculate thermal quantum expectation values. This method can handle Hamiltonians with non‐linear terms, which are important for describing uniaxial anisotropies and mechanical constraints.

Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

Advanced Physics Research, Volume 4, Issue 7, July 2025.
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Advanced Physics Research, Volume 4, Issue 7, July 2025.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

A simple approach to biophysical profiling of blood cells in extranodal NK/T cell lymphoma patients using deep learning‐integrated image cytometry

BMEMat, Volume 3, Issue 2, June 2025.
We developed a deep learning‐integrated image cytometry technique to profile biophysical attributes of blood cells from ENKTL patients. We demonstrate specific changes in cell size, eccentricity, and refractive index during treatment in a label‐free manner.

Simulation of bright and dark diffuse multiple scattering lines in high‐flux synchrotron X‐ray experiments

Journal of Applied Crystallography, Volume 58, Issue 3, Page 859-868, June 2025.
This research introduces a theoretical framework for analysing diffuse multiple scattering in single crystals. Using high‐intensity synchrotron X‐rays, the model accurately predicts the intensity distribution along Bragg cones, taking into account both general diffuse scattering and mosaicity to understand complex material behaviour, especially in ...

Sequential testing of complementary hypotheses about population density

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1228-1238, June 2025.
Abstract Making inferences about population density is paramount in ecology and pest management for decision‐makers who often seek to determine how a population compares to a pre‐established static or dynamic threshold through sampling or monitoring. Sequential data analysis is appealing for monitoring and decision making as it is more cost‐efficient ...
