Human Brain Mapping, Volume 46, Issue 10, July 2025.Dysfunctional hierarchy in major depressive disorder (MDD) features decreased SDI in regions linked to high‐order cognitive functions, like the prefrontal, parietal, and orbitofrontal cortices. Conversely, areas related to low‐level sensory‐motor functions, the somatosensory cortex, showed increased SDI in MDD.

Eigenvalue Approach to Dense Clusters in Hypergraphs
Journal of Graph Theory, Volume 109, Issue 3, Page 353-365, July 2025.ABSTRACT In this article, we investigate the problem of finding in a given weighted hypergraph a subhypergraph with the maximum possible density. Using the notion of a support matrix we prove that the density of an optimal subhypergraph is equal to ∥ A T A ∥ for an optimal support matrix A. Alternatively, the maximum density of a subhypergraph is equal

Electrospinning of Well‐Aligned P(VDF‐TrFE) Fibers Using a Benign Solvent
Macromolecular Rapid Communications, Volume 46, Issue 13, July 04, 2025.The role of solvent properties is explored in electrospinning a piezoelectric polymer popular in electromechanical devices. The relationship between solvent boiling point, process stability and fiber quality is viewed through the lens of morphological and crystalline phase characterization.

A viscous fluid model for large‐scale motion estimation in image‐guided radiotherapy
Medical Physics, Volume 52, Issue 7, July 2025.Abstract Background Image‐guided radiotherapy (IGRT) is often hampered by geometric inaccuracies introduced by anatomical and physiological motion. Although a wide array of deformable image registration (DIR) solutions have been proposed toward motion estimation and compensation during IGRT, their accuracy and precision generally deteriorates within ...

Hydrodynamics of Fault Gouges From Constitutive Modelling to the Physics of Friction
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.Abstract The development of rate‐ and state‐dependent friction laws offered important insights into the key physical mechanisms of the frictional behavior of fault gouges and their seismic cycle. However, past approaches were specifically tailored to address the problem of fault shearing, leaving questions about their ability to comprehensively ...

A Review of Green's Function Methods for Tracer Timescales and Pathways in Ocean Models
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 7, July 2025.Abstract Understanding advective‐diffusive dispersal of trace substances in environmental fluids like the global ocean is a ubiquitous challenge in geophysics. Since the turn of the millennium, substantial progress has been made in the theory, implementation in models, and application of such tracers in oceanography.

Fractional Laplacian with Supercritical Killings
Communications in Mathematical PhysicsIn this paper, we study Feynman-Kac semigroups of symmetric $\alpha$-stable processes with supercritical killing potentials belonging to a large class of functions containing functions of the form $b|x|^{-\beta}$, where $b>0$ and $\beta>\alpha$. We obtain two-sided estimates on the densities $p(t, x, y)$ of these semigroups for all $t>0$, along with ...
