Thermal Planar and Radial Free Jets for An Ostwald‐de Waele Fluid With Shear‐Rate Dependent Thermal Diffusivity

Mathematical Methods in the Applied Sciences, Volume 49, Issue 10, Page 10312-10333, 15 July 2026.
ABSTRACT The planar and radial thermal free jets for forced convection of a non‐Newtonian power‐law fluid are investigated. The thermal diffusivity is dependent on the shear‐rate and is not a constant. The flow in planar and radial thermal free jets is governed by the momentum, continuity and energy balance equations. In the stream‐function formulation,

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

A Numerical Alternative to MR Thermometry for Safety Validation of Multi‐Channel RF Transmit Coils

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 469-484, July 2026.
ABSTRACT Purpose This study proposes a numerical technique to estimate peak local specific absorption rate (SAR) uncertainty of multi‐channel RF coils during the process of safety validation as an alternative to experimental temperature and electric‐field measurements, and demonstrates its use to enable human studies at 10.5 T.

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 ...

Source Scaling of Shallow Volcano‐Tectonic Earthquakes at Piton de la Fournaise Volcano (La Réunion, France) Estimated From Codas of Seismograms

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Despite their importance for understanding faulting processes in volcanic environments, the source scaling of volcano‐tectonic earthquakes remains poorly constrained, mainly due to the difficulty of measuring their source parameters. We analyze source parameters such as seismic moments (M0 ${M}_{0}$) and corner frequencies (fc ${f}_{c}$) of ...

Non‐Uniqueness, Symmetries and Invariance of Thermal History Modelling in Sedimentary Basins

Basin Research, Volume 38, Issue 4, July–August 2026.
This paper approaches non‐unique inverse problems by generating a representative ensemble of all possible solutions using the concept of symmetry. In the context of basin modelling, a symmetry is any manipulation of a forward model's parameters (e.g., thermal history) that leaves the model output (e.g., downhole vitrinite reflectance) unchanged ...
