Restriction‐Weighted Q‐Space Trajectory Imaging (ResQ): Toward Mapping Diffusion‐Time Effects With Tensor‐Valued Diffusion Encoding in Human Prostate Cancer Xenografts

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Tensor‐valued diffusion MRI enables microstructure characterization but can be confounded by the presence of restricted diffusion. We introduce ResQ, a framework that incorporates restriction weighting into q‐space trajectory imaging and we evaluate it in a longitudinal study of prostate cancer xenografts treated by external radiotherapy. ResQ revealed

The Mathematical History Behind the Granger–Johansen Representation Theorem

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 587-602, August 2026.
ABSTRACT When can a vector time series that is integrated once (i.e., becomes stationary after taking first differences) be described in error correction form? The answer to this is provided by the Granger–Johansen representation theorem. From a mathematical point of view, the theorem can be viewed as essentially a statement concerning the geometry of ...

Least Trimmed Squares: Cointegration and Outliers

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 690-711, August 2026.
ABSTRACT When applying the cointegrated autoregressive distributed lag model it is common to include indicator variables for outliers. This is often done in a somewhat ad hoc way. Least Trimmed Squares estimation provides a more systematic approach. This estimator is robust to a large number of outliers of many types.

Comment on “Can Charge Transfer Across C─H···O Hydrogen Bonds Stabilize Oil Droplets in Water?”

Angewandte Chemie, Volume 138, Issue 28, 6 July 2026.
Nanoscale oil droplets in water are kinetically stable and charged, with a pH dependent electrophoretic mobility. Although the source of this charge is agreed to arise from water, 2 main hypotheses remain: OH− adsorption or electronic charge density displaced via hydrogen bonds. Molecular surface specific experiments are reviewed, that all point to the

Deep Learning‐Based Phase‐Field Modelling of Brittle Fracture in Anisotropic Media

International Journal for Numerical Methods in Engineering, Volume 127, Issue 13, 15 July 2026.
ABSTRACT This work presents a variational physics‐informed deep learning framework for phase‐field modelling of brittle crack propagation in anisotropic media. Previous variational energy‐based neural network (NN) approaches have focused on second‐order, isotropic phase‐field fracture formulations and have relied on fully connected NNs.

Overcoming Computational Bottlenecks in Quantum Hydrodynamics: A Volume‐Based Integral Formalism for Spherical Nanoparticles

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Numerical modeling of mesoscopic material response models that capture the quantum dynamics of electrons does not have to come with discouraging computational bottlenecks. The main message is that through a shift in perspective in modeling toward integral equation methods and exploiting symmetry‐based arguments, it is possible to capture complicated ...
