Mutations Alter Conformations and Dynamics of APP‐TMDs: An RDC Analysis

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
How γ‐secretase selects its substrates has been an enigma because of the lack of a consensus sequence. Using residual dipolar couplings, we analyzed the conformations of one substrate and two mutants. Using snapshots of a molecular dynamics trajectory, we analyzed how well structures matched the measured RDC values.

Frequency‐Domain Subspace Identification for Noninvasive Transformer Winding Parameter Estimation and Fault Diagnostics

open access: yesInternational Journal of Circuit Theory and Applications, Volume 54, Issue 2, Page 658-677, February 2026.
Noninvasive frequency‐domain method estimates transformer winding parameters from terminal measurements, eliminating the need for design data. ABSTRACT A novel frequency‐domain subspace identification method enables precise estimation of transformer winding ladder network parameters directly from terminal measurements.

Selection of Potential Potato Cultivars With Export Quality Through Multitrait Genotype‐Ideotype Distance Index (MGIDI)

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Ranking and selection of potato varieties using the MGIDI index. MGIDI analysis identified six superior genotypes viz., BARI Alu‐7, BARI Alu‐40, BARI Alu‐46, BARI Alu‐97, BARI Alu‐62, and BARI Alu‐37 considering a selection intensity of 20%. These genotypes demonstrated strong performance, revealing both their strengths and weaknesses in relation to ...

Accelerated Diffusion Basis Spectrum Imaging With Tensor Computations

open access: yesHuman Brain Mapping, Volume 47, Issue 2, February 1, 2026.
We introduce a new framework for accelerated processing of diffusion‐weighted imaging (DWI) data using a machine learning approach to optimize parameter estimation. We demonstrate that this new method, called DBSIpy, significantly improves computational speed and robustness to Rician noise compared to the standard DBSI method, with the improvements ...

How Far Are Two Symmetric Matrices From Commuting? With an Application to Object Characterisation and Identification in Metal Detection

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 1914-1942, February 2026.
ABSTRACT Examining the extent to which measurements of rotation matrices are close to each other is challenging due measurement noise. To overcome this, data is typically smoothed, and the Riemannian and Euclidean metrics are applied. However, if rotation matrices are not directly measured and are instead formed by eigenvectors of measured symmetric ...

Few‐shot learning for highly accelerated 3D time‐of‐flight MRA reconstruction

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 770-786, February 2026.
Abstract Purpose To develop a deep learning‐based reconstruction method for highly accelerated 3D time‐of‐flight MRA (TOF‐MRA) that achieves high‐quality reconstruction with robust generalization using extremely limited acquired raw data, addressing the challenge of time‐consuming acquisition of high‐resolution, whole‐head angiograms.
