Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The role of inherited lithospheric structures in active rift seismicity and magma intrusion remains a key uncertainty in continental breakup dynamics. We investigate the January 2025 Northern Main Ethiopian Rift swarm using constrained 3‐D gravity inversion and D‐InSAR observations to characterize crustal architecture, seismicity, and active ...

Infinite horizon economies with borrowing constraints [PDF]
We consider infinite horizon economies with incomplete financial markets. Securities are in positive net supply and may be infinite-lived. We establish existence of equilibria by requiring borrowing constrains instead of portfolio restrictions ...

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presence of aseismic slip and compare this behavior with structural evidence from

Ionospheric tomography by Over-The-Horizon radar
, 2014 La plupart des méthodes récentes de tomographie de l’ionosphère sont basées sur l'inversion du contenu électronique total mesuré par des récepteurs GPS basés au sol. A cause de la haute fréquence du signal GPS et l'absence de rayon horizontal, la structure de la densité électronique est principalement reconstruite dans la région F2 (300 km d’altitude),

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

Advanced Science, Volume 13, Issue 49, 3 September 2026.This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...

Applied Numerical Modelling of Landscape Evolution in Anthropogenic Landscapes: A Systematic Review
Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.This systematic review examines how landscape evolution models have been applied to analyse long‐term change in anthropogenic landscapes. The review evaluates modelling approaches, applications, limitations and key knowledge gaps to assess the potential of these models for long‐term landscape and risk management.
