Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

International Journal for Numerical Methods in Fluids, Volume 98, Issue 7, Page 804-839, July 2026.
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

Decoding the Structural Complexity of Fungal α‐ and β‐Glucan Matrix via Statistical Analysis of Solid‐State NMR Chemical Shifts

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
Solid‐state NMR combined with principal component analysis enables quantitative classification of fungal α‐ and β‐glucan architectures in intact cell walls, revealing conserved triple‐helical β‐1,3‐glucan conformations across species and predominantly bundled‐sheet α‐1,3‐glucan assemblies with condition‐dependent polymorphism. Statistical clustering of

A MR Fingerprinting Development Kit for Quantitative 3D Brain Imaging

Journal of Magnetic Resonance Imaging, Volume 64, Issue 1, Page 209-217, July 2026.
ABSTRACT Background Magnetic resonance fingerprinting (MRF) is an emerging quantitative imaging technique that enables multiparametric tissue characterization, but its adoption has been hindered by the complexity of data acquisition and post‐processing. These technical and implementation challenges have limited its broader clinical deployment.

Modelling Motion‐Induced Signal Corruption in Steady‐State Diffusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 66-82, July 2026.
ABSTRACT Purpose Diffusion‐weighted steady‐state free precession (DW‐SSFP) is a diffusion imaging sequence achieving high SNR efficiency. A key challenge for in vivo DW‐SSFP is the sequence's severe motion sensitivity, currently limiting investigations to low or no motion regimes.

Simulation‐Informed Evaluation of Microvascular Parameter Mapping for Diffusion MR Imaging of Solid Tumours

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 387-402, July 2026.
ABSTRACT Purpose We aim to inform the design of new diffusion MRI (dMRI) approaches for microvasculature quantification that enhance the biological specificity of imaging towards cancer. Methods We adopted simulation‐informed modelling of the vascular dMRI signal. We synthesised signals from 1500 synthetic vascular networks, for a variety of protocols (

Enhanced 2D Spiral Cine DENSE MRI Using Low‐Rank Denoising for Improved Apparent Signal‐to‐Noise Ratio, Spatial Resolution, Efficiency, Accuracy, and Accessibility

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 403-419, July 2026.
ABSTRACT Purpose To develop a denoising technique for displacement encoding with stimulated echoes (DENSE) MRI that improves spatial resolution, efficiency, and accuracy, and enhances accessibility by implementing DENSE MRI at 0.55 T. Methods We developed a low‐rank denoising technique, which leverages multidimensional spiral cine DENSE MRI data for ...

Autonomy for MRI Field Cameras: Synchronization, Self‐Calibration, and Sequence Detection

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 485-498, July 2026.
ABSTRACT Purpose This work aims to provide a workflow for operating NMR field probes in MR scanners independently of pulse programming, scanner TTL trigger pulses and dedicated calibration sequences. Methods An independent timing system and limited prior knowledge about relative probe positions enable synchronous field measurement, probe position ...

Multiparametric Free‐Breathing 3D Whole‐Heart Cardiac MR for Anatomical Bright‐ and Black‐Blood Imaging With Co‐Registered T1/T2$$ {T}_1/{T}_2 $$ Myocardial Tissue Mapping at 0.55$$ 0.55 $$ T

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
Novel 3D CMR free‐breathing whole‐heart sequence demonstrated the feasibility of high‐resolution coronary angiography and simultaneous bright‐ and black‐blood imaging, together with joint T1/T2$$ {T}_1/{T}_2 $$ mapping despite the inherent limitations of low‐field strength at 0.55 T, suggesting its potential for comprehensive cardiac assessment in ...

Unraveling the spatial landscape of dystrophinopathies: a transcriptomic approach to Becker and Duchenne muscular dystrophies

The Journal of Pathology, Volume 269, Issue 3, Page 363-380, July 2026.
Abstract Dystrophinopathies are caused by pathogenic variants in the DMD gene, resulting in partial (Becker) or complete loss (Duchenne) of dystrophin. Becker (BMD) and Duchenne muscular dystrophy (DMD) are characterized by progressive muscle wasting, fatty replacement, fibrosis, and loss of function.
