Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

Sea Surface Height Inversion Model Based on Multimodal Deep Learning for the Fusion of Heterogeneous FY-3E GNSS-R Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Sea surface height (SSH) is of great significance in oceanography and meteorology. Traditional physical altimetry methods based on delay–Doppler mapping (DDM) are subject to errors that are difficult to correct computationally.

Analysis of Ionospheric Disturbances Near 120°E in the Asia‐Pacific Sector During the May 2024 Superstorm Using Multi‐Instrument Observations

Space Weather, Volume 24, Issue 2, February 2026.
Abstract On 10 May 2024, a severe G5 geomagnetic storm—the most intense of solar cycle 25—significantly disturbed the global ionosphere. This study presents a comprehensive analysis using multi‐instrument observations, including ground‐based measurements from BDS‐GEO total electron content (TEC), digital ionosondes, and magnetometers; model outputs ...

Inequalities and counterexamples for functional intrinsic volumes and beyond

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We show that analytic analogs of Brunn–Minkowski‐type inequalities fail for functional intrinsic volumes on convex functions. This is demonstrated both through counterexamples and by connecting the problem to results of Colesanti, Hug, and Saorín Gómez.
