Role of Volcano‐Tectonic Interactions During Early‐Phase Magma‐Assisted Continental Rifting

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract We study volcanic‐tectonic interactions during the early phase of rifting in the Natron Rift, a magmatic segment of the East African Rift System. We use the open‐source crustal deformation modeling code, PyLith, to model deflation during the 2007–2008 explosive eruptions and inflation during 2016–2023.

Variograms across spatial scales using graph geodesics and diffusion distances in heterogeneous permeability fields

Discover Geoscience
Classical variogram analysis groups squared increments by Euclidean separation. This choice is natural in homogeneous or approximately isotropic domains, but it can be misleading in heterogeneous permeability fields where physical coupling is controlled ...

Nonlinear Extreme‐Heat Responses to the Spatial Progression of Deforestation in the Maritime Continent

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Maritime Continent (MC) has undergone rapid deforestation in recent decades, altering its land‐atmosphere energy balance. Using idealized Community Earth System Model simulations, we examined heat extremes under progressively increasing deforestation extents, from localized coastal clearing to complete forest removal.

Stability of evolving cluster of stars and exotic matter

European Physical Journal C: Particles and Fields
This paper discusses the phenomenon of evolving spherically symmetric cluster of stars in the presence of an exotic matter. To discuss evolutionary mechanism, we use the Starobinsky model of f(R) gravity as exotic matter and the structure scalars as ...

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

A Recursive Scheme of First Integrals of the Geodesic Flow of a Finsler Manifold

Symmetry, Integrability and Geometry: Methods and Applications, 2007
We review properties of so-called special conformal Killing tensors on a Riemannian manifold $(Q,g)$ and the way they give rise to a Poisson-Nijenhuis structure on the tangent bundle $TQ$.

Cross-modality mapping using image varifolds to align tissue-scale atlases to molecular-scale measures with application to 2D brain sections

Nature Communications
This paper explicates a solution to building correspondences between molecular-scale transcriptomics and tissue-scale atlases. This problem arises in atlas construction and cross-specimen/technology alignment where specimens per emerging technology ...

Long‐Lived Anticyclonic Eddies Facilitate Convection in the Greenland Sea Over Multiple Consecutive Winters

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Wintertime open‐ocean convection is a key process in renewing deep water; however, the processes that promote convection on local scale remain poorly understood. We investigate the role of long‐lived anticyclonic eddies in facilitating deep convection in the Greenland Sea using a new model simulation and observations.

Adaptive Centroidal Voronoi Tessellation With Agent Dropout and Reinsertion for Multi-Agent Non-Convex Area Coverage

IEEE Access
Voronoi diagrams are widely used for area partitioning and coverage control. Nevertheless, their utilization in non-convex domains often necessitates additional computational procedures, such as diffeomorphism application, geodesic distance calculations,
