AGU Advances, Volume 7, Issue 3, June 2026.Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

Machine Learning for Local Detection of Separators in Three‐Dimensional Magnetic Fields
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Magnetic reconnection is a major plasma phenomenon occurring in various key environments ranging from the Sun and near‐Earth space to astrophysical plasmas. While magnetic reconnection is relatively well‐understood under two‐dimensional (2D) settings, it remains challenging to characterize in three‐dimensional (3D) magnetic fields.

International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.

Fast Transitions of X-Ray Variability in the Neutron Star Low-mass X-Ray Binary Cygnus X-2
The Astrophysical JournalWe present a spectral-timing analysis of two NICER observations of the weakly magnetized neutron star low-mass X-ray binary Cygnus X-2. During these observations, we detect a rapid transition from a narrow 50 Hz horizontal-branch oscillation (HBO) to a ...

Earth and Space Science, Volume 13, Issue 5, May 2026.Abstract Sediments on Arctic continental shelves are impacted by sea ice and ice‐related processes for up to 9 months per year. As a result, seabed morphology in cold regions can exhibit features such as ice scours which are absent on lower‐latitude shelves.

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

European Physical Journal C: Particles and FieldsCosmogenic muon-induced radioactive isotopes pose a significant background source for deep-underground low-background experiments. Although rock overburdens at underground sites substantially attenuate the cosmogenic muon flux, residual muon-induced ...
