The Contribution of Time Domain Structures to Electron Loss During the 17 March 2013 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Ring current modeling has been a subject of active research in the last two decades. However, accurately modeling of this population of particles remains a challenge. Several recent studies have demonstrated that ring current models can overestimate the trapped electron flux in the 10–50 keV range by up to two orders of magnitude during ...

ULF Wave Modulation of Energetic Electron Precipitation Caused by the Self‐Limiting of Space Radiation: May 2024 Superstorm Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The May 2024 geomagnetic superstorm provided the opportunity to explore how strong wave‐particle interactions affect energetic electron precipitation under intense driving. Using coordinated measurements from a balloon‐borne Timepix‐based X‐ray detector, ground‐based riometers and magnetometers, and Arase satellite observations, we identified ...

Joule Heating in the Northern Hemisphere During Geomagnetic Storms Driven by High‐Speed Streams and Coronal Mass Ejections

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We present a robust method for estimating the auroral Joule heating in the northern hemisphere by combining SuperMAG, SuperDARN and AMPERE data products. This method is applied to 292 storms during 2010–2023. Temporal evolution and spatial distributions of the storm‐time Joule heating are studied using a superposed epoch analysis, with the ...

A Statistical Analysis of the Wave‐Particle Dynamics Near the Kennel‐Petschek Limit

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract This study investigates how electron fluxes and chorus waves behave relative to the Kennel–Petschek (K‐P) flux limit using 7 years of Van Allen Probes observations. We combine spatial statistics of when the K‐P limit is exceeded, energy‐dependent flux–wave relationships, and frequency‐resolved chorus spectra to provide a more comprehensive ...

Identification of Interactive Genetic Loci Linked to Insulin Resistance in Metabolic Syndrome—An Update

Medicina
Metabolic syndrome is a metabolic disorder characterized by hypertension, dyslipidemia, impaired glucose tolerance, and abdominal obesity. Impaired insulin action or insulin resistance initiates metabolic syndrome. The prevalence of insulin resistance is

Imputing Missing Long‐Term Spatiotemporal Multivariate Atmospheric Data With CNN‐Transformer Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Continuous physical domains are important for scientific investigations of dynamical processes in the atmosphere. However, missing data—arising from operational constraints and adverse environmental conditions—pose significant challenges to accurate analysis and modeling.

Unraveling Super Equatorial Plasma Bubbles (EPBs) Evolution During the 23 April 2023 Storm: Multi‐Instrument Observations and GITM‐SAMI3 Simulation

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Storm‐time equatorial plasma bubble (EPB) dynamics play a critical role in space weather impacts on communication and navigation systems, yet the mechanisms governing their formation and evolution under storm conditions remain poorly understood.
