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

open access: yesMagnetic 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

open access: yesNMR 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 ...

Spatio-Temporal Multiway Data Decomposition Using Principal Tensor Analysis on k-Modes: The R Package PTAk

open access: yes
The purpose of this paper is to describe the R package {PTAk and how the spatio-temporal context can be taken into account in the analyses. Essentially PTAk() is a multiway multidimensional method to decompose a multi-entries data-array, seen ...

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

open access: yesThe 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.

Assessing the Worth of Noble Gas Tracer Concentrations in Alluvial River‐Aquifer Systems Using Data Space Inversion

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract Alluvial systems are dynamic, structurally complex environments. Groundwater that is extracted from these systems is widely used for domestic consumption. Numerical models play an important role in the management of this extraction. To provide support for decision‐making, models must assimilate data that inform the spatial and temporal ...

Matrix Singular Value Decomposition

open access: yes, 2010
This thesis starts with the fundamentals of matrix theory and ends with applications of the matrix singular value decomposition (SVD). The background matrix theory coverage includes unitary and Hermitian matrices, and matrix norms and how they relate to ...

Integrating Soil Taxonomy With Soil and Remote Sensing Indices for Site‐Specific Management in the Egyptian Nile Delta Fringes

open access: yesSoil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT Sustainable soil management in arid regions is constrained by the limited translation of subgroup‐level soil taxonomy into site‐specific agronomic recommendations. Hence, this study integrated field observations and laboratory analyses from 18 soil profiles with freely available Google Earth Engine (GEE) datasets.

Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 16, 4 June 2026.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

The singular value decomposition and applications in geodesy

open access: yes, 2010
The paper considers the singular value decomposition (SVD) of a general matrix. Some immediate applications, such as determining the spectral and Frobenius norm, rank and pseudoinverse of the matrix are described.
