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).

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 ...

Rapid Recharge and Descent of Thundercloud Core Producing Gamma‐Ray Glow
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.Abstract We report two gamma‐ray glows observed on 22 December 2023, during a winter thunderstorm in Japan, using an array of four radiation detectors. The first glow, detected by one sensor, was quenched by a lightning discharge. The second glow appeared 2–3 min later and was tracked by three other detectors.
