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.

UniverseWe investigate a static and spherically symmetric Schwarzschild–Letelier Black Hole immersed in a King Dark Matter Halo and analyze how the combined effects of the cloud of strings and the dark-matter environment modify the spacetime geometry, particle ...

A relative Poincaré–Birkhoff theorem
Bulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.Abstract A. Moreno and Otto van Koert proved a generalised version of the classical Poincaré–Birkhoff theorem, for Liouville domains of any dimension. In this article, we prove a relative version for Lagrangians with Legendrian boundary. This gives interior chords of arbitrary large length, provided that the twist condition introduced by Moreno and van

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The floods of 01 September 2009 in Ouagadougou, Burkina Faso, were among the most severe in the Central Sahel's history, highlighting the region's persistent flood risk. This extreme precipitation event (EPE) was influenced by various atmospheric drivers, including Convectively Coupled Equatorial Waves (CCEWs).

Gradient Vector Flow Fast Geodesic Active Contours
, 2001 This paper proposes a new front propagation flow for boundary extraction. The proposed framework is inspired by the geodesic active contour model and leads to a paradigm that is relatively free from the initial curve position.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract We performed a stress tensor inversion using focal mechanisms from intermediate‐depth and deep earthquakes to estimate the stress regime of the Pacific slab beneath southwestern Japan. We focused on the temporally averaged stress field derived from the recent 28‐year data set of the F‐net CMT solutions.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Mercury experiences the most intense and variable solar wind (SW) conditions in the solar system due to its close, eccentric orbit about the Sun. In addition to variation driven by coronal source and solar cycle, the SW arriving at Mercury varies periodically as the planet's heliocentric distance changes by over 50% per orbit.

Relativistic Dynamics of Vector Bosons in the Field of Gravitational Radiation [PDF]
, 2001 We consider a model of the state evolution of relativistic vector bosons, which includes both the dynamical equations for the particle four-velocity and the equations for the polarization four-vector evolution in the field of a nonlinear plane ...

The Lorenz manifold as a collection of geodesic level sets
, 2004 We demonstrate a method to compute a two-dimensional global stable or unstable manifold of a vector field as a sequence of approximate geodesic level sets.

A New Family of Buckled Rings on the Unit Sphere
MathematicsBuckled rings, also known as pressurized elastic circles, can be described as critical points for a variational problem, namely the integral of a quadratic polynomial in the geodesic curvature of a curve. Thus, they are a generalization of elastic curves,
