Advanced Science, Volume 13, Issue 4, 19 January 2026.Upon ischemia/reperfusion‐induced iron overload condition, neurons and astrocytes exhibit similar oxidative stress changes but opposite alterations in endogenous antioxidant defense mechanisms, leading to divergent ferroptotic outcomes. The iron deposition and neuronal loss are increased within the perilesional cortex of stroke patients ...

A Study on the k-Mersenne and k-Mersenne-Lucas Sequences
Universal Journal of Mathematics and ApplicationsIn this study, we examine an application of $k-$Mersenne and $k-$Mersenne-Lucas sequences. We present the Catalan transforms of these sequences and give the properties of these Catalan transforms. Catalan transforms of $k-$Mersenne and $k-$Mersenne-Lucas

Delayformer: Spatiotemporal Transformation for Predicting High‐Dimensional Dynamics
Advanced Science, Volume 13, Issue 3, 14 January 2026.Delayformer introduces a multivariate spatiotemporal transformation (mvSTI) that converts observed variables into delay‐embedded states and cross‐learns their dynamics using a shared Vision Transformer encoder. This approach, grounded in dynamical systems theory, simultaneously predicts all variables in high‐dimensional systems, outperforming state‐of ...

Accelerated water residual removal in MRS: Exploring deep learning versus fitting‐based approaches
Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 38-50, January 2026.Abstract PurposeRemoving water residual signals from MRS spectra is crucial for accurate metabolite quantification. However, currently available algorithms are computationally intensive and time‐consuming, limiting their clinical applicability. This work aims to propose and validate two novel pipelines for fast water residual removal in MRS. MethodsTwo

Gradient Scheme Optimization for PRESS‐Localized Edited MRS Using Weighted Pathway Suppression
NMR in Biomedicine, Volume 39, Issue 1, January 2026.This study presents an optimized DOTCOPS‐based gradient scheme for PRESS‐localized edited MRS that integrates a volume‐based likelihood model to prioritize suppression of unwanted coherence transfer pathways. Using a dual‐penalty genetic algorithm, the scheme achieved a 197% increase in k‐space crushing efficiency and significantly reduced out‐of‐voxel

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.This paper presents a robust H∞ decentralised and centralised control approach for a microsurgical manipulator using Particle Swarm Optimisation and Gravitational Search Algorithm (PSOGSA). The proposed fixed‐structure Proportional‐Integral‐Derivative (PID)‐based controllers address implementation challenges of conventional high‐order H∞ controllers ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.In this paper, we first establish the dual‐band airborne radar wideband echo signal model and propose a space‐time‐frequency adaptive processing method based on it. Firstly, in the passive mode, the poles of the dual band are estimated by the matrix pencil method, and the incoherent components are estimated through the phase relationship between the ...
