Unusual shrinkage and reshaping of Earth’s magnetosphere under a strong northward interplanetary magnetic field

Communications Earth & Environment, 2023
Open magnetic flux in the polar cap almost completely disappeared and the Earth’s magnetotail was compressed into a calabash shape during the 9th April 2015 coronal mass ejection, according to magnetohydrodynamic simulations and observations from DMSP ...

Pathogenic Variants in HEPACAM Alter Protein Localization and Interactome in Astrocytes of the Developing Mouse Cortex

Glia, Volume 74, Issue 11, November 2026.
Pathogenic variants alter hepaCAM protein distribution. Astrocyte‐specific hepaCAM TurboID reveals KCNQ2 as a new interaction partner. Pathogenic variants alter hepaCAM association with key transmembrane proteins. ABSTRACT Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a rare leukodystrophy characterized by early‐onset macrocephaly,

Solar Mass Ejections and Coronal Holes [PDF]

International Astronomical Union Colloquium, 1996
AbstractIn this paper we present observations of two types of solar mass ejections, which seem to be associated with the location of coronal holes. In the first type, a filament eruption was observed near a coronal hole, which gave rise to a strong interplanetary scintillations, as detected by IPS observations.

Study of Evolution and Geo-effectiveness of Coronal Mass Ejection–Coronal Mass Ejection Interactions Using Magnetohydrodynamic Simulations with SWASTi Framework

The Astrophysical Journal
The geo-effectiveness of coronal mass ejections (CMEs) is a critical area of study in space weather, particularly in the lesser-explored domain of CME–CME interactions and their geomagnetic consequences.

“Two‐For‐One”: 4D Cardiac and Pulmonary MR Imaging From a Single Acquisition Using bSTAR

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2213-2227, November 2026.
ABSTRACT Purpose To generate 4D (3D+time) images of both the heart and lungs using a single volumetric radial free‐breathing bSSFP dual echo acquisition (bSTAR) with two image reconstructions within a single pipeline deployed inline at 0.55 and 1.5 T.

Low Coronal Signatures of a Coronal Mass Ejection [PDF]

Proceedings of the International Astronomical Union, 2004
Using the observations of the EUV Imaging Telescope(EIT) and the Large Angle Spectrometric Coronagraph(LASCO) on the Solar and Heliospheric observatory(SOHO) and solar soft X-ray flux and radio bursts data, we study the low coronal signatures of a solar limb coronal mass ejection(CME) on November 4, 2003.

An Improved Halo Coronal Mass Ejection Geoeffectiveness Prediction Model Using Multiple Coronal Mass Ejection Features Based on the DC-PCA-KNN Method

The Astrophysical Journal
Coronal mass ejections (CME) are regarded as the main drivers of geomagnetic storms (GSs). In the prediction of geoeffectiveness, various CME features have been introduced without adequately considering the geoeffectiveness of CMEs and strong ...

Radial Tiny Golden Angle UTE (tyGA‐UTE) for Cardiac MRI in the Small Animal Model

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
This study validates an 11.7‐T ultra‐high‐field tyGA‐UTE cardiac MRI workflow for murine models, featuring single‐acquisition dual reconstructions for real‐time visualization and quantitative functional assessment. It delivers performance equivalent to standard techniques, excellent reproducibility, and higher efficiency by eliminating repeated scans ...

Coronal Mass Ejections: Observations [PDF]

Living Reviews in Solar Physics, 2012
Solar eruptive phenomena embrace a variety of eruptions, including flares, solar energetic particles, and radio bursts. Since the vast majority of these are associated with the eruption, development, and evolution of coronal mass ejections (CMEs), we focus on CME observations in this review. CMEs are a key aspect of coronal and interplanetary dynamics.

Exploring Jupiter's Mid‐Latitude Dusk Magnetopause: The Impact of Magnetic Reconnection

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The Juno mission has elucidated magnetosphere processes, structure, and dynamics via multi‐instrument plasma and magnetic field observations. In this study, these instruments are used to identify magnetic reconnection during the Juno extended mission from a survey of 490 magnetopause crossings at the mid‐latitude southern dusk magnetopause ...
