Space Weather, Volume 24, Issue 1, January 2026.Abstract Solar Particle Events (SPEs) represent one of the most significant hazards to future crewed space missions. Accurate assessment of radiation doses received by astronauts during these events is essential for determining the shielding requirements in spacecraft and off‐planet shelter design.

Forecasting SEP Atmospheric and Space Radiation by Coupling UMASEP and NAIRAS Models
Space Weather, Volume 24, Issue 1, January 2026.Abstract The Nowcast of Aerospace Ionizing RAdiation System (NAIRAS) model predicts the radiation environment from the Earth's surface to free‐space. The model output provides dosimetric and particle flux quantities required to assess the hazardous radiation impacts to human health and adverse effects on vehicle electronic systems.

Deep Learning‐Based Gas Holdup Detection in Plunger Lift Systems: A VGG‐Unet Approach
IET Image Processing, Volume 20, Issue 1, January/December 2026.In the realm of oil and gas engineering, plunger lift systems are vital for mitigating liquid loading in gas wells. This study introduces a deep learning‐based approach for detecting gas holdup in the annulus of plunger lift systems, leveraging the VGG‐Unet architecture.

Acta Physiologica, Volume 242, Issue 1, January 2026.ABSTRACT Aim The circadian clock in the suprachiasmatic nuclei of the hypothalamus (SCN) is resistant to glucocorticoids (GC) in adults but responds to dexamethasone (DEX) during the fetal stage. Previously, this resistance of the adult SCN clock was attributed to a developmental loss of the glucocorticoid receptor (GR).

Optimising a current‐rate controlled flash sintering process for UO2 pellet fabrication
Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Abstract Field assisted sintering techniques (FASTs) are currently being presented as an attractive alternative to the energy and time intensive fabrication routes employed for UO2 and MOx nuclear fuel manufacture. Current‐rate controlled flash sintering (CR‐FS) is a novel variant of typical flash sintering (FS) methods that permits heightened sample ...

Description and modeling of the Jiddat al Harasis 091 L5 strewn field
Meteoritics &Planetary Science, Volume 61, Issue 1, Page 107-121, January 2026.Abstract With a size of 51.2 × 7.2 km, the 10.9 ± 1.7 ka old Jiddat al Harasis 091 L5 chondrite strewn field is the largest known in Oman. It consists of more than 700 meteorites with a total mass of >4.5 tons from which the largest six stones of >100 kg to 1.5 tons make up two thirds of the total mass.

MOS and RREA Processes in Thunderclouds: Intensities and Spectral Shapes
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract The Relativistic Runaway Electron Avalanche (RREA) is the primary mechanism for enhancing atmospheric electron and gamma‐ray fluxes when the electric field exceeds a density‐dependent threshold. Another, non‐threshold process—Modification of the Electron Energy Spectrum (MOS)—occurs when subcritical fields energize ambient electrons, shifting ...
