Deciphering the Slow-rise Precursor of a Major Coronal Mass Ejection
The Astrophysical Journal Letters, 2023 Coronal mass ejections are explosive plasma phenomena prevalently occurring on the Sun and probably on other magnetically active stars. However, how their pre-eruptive configuration evolves toward the main explosion remains elusive.

Coronal dimming as a proxy for stellar coronal mass ejections [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractSolar coronal dimmings have been observed extensively in the past two decades and are believed to have close association with coronal mass ejections (CMEs). Recent study found that coronal dimming is the only signature that could differentiate powerful flares that have CMEs from those that do not.

Solar Coronal Mass Ejection and Post–Coronal Mass Ejection Blob Formation in Two-fluid Simulations
The Astrophysical JournalA coronal mass ejection (CME) and post-CME blob phenomena in the solar atmosphere, associated with shear flow and convergent flow perturbations in the photosphere, are investigated using a resistive two-fluid (electron–ion) code.

The Inhomogeneity of Composition Along the Magnetic Cloud Axis
Frontiers in Physics, 2021 Coronal mass ejections (CMEs) are one of the most energetic explosions in the solar system. It is generally accepted that CMEs result from eruptions of magnetic flux ropes, which are dubbed as magnetic clouds (MCs) in interplanetary space.

Drug Repurposing for Treating NCOR‐Related Intellectual Disability
Advanced Science, EarlyView.An autism‐associated NCOR1 heterozygous mutation upregulates NRGs and activates NRG backward signaling in hypothalamic GABAergic neurons in mouse models, leading to Gabra2 downregulation and cognitive deficits, which can be therapeutically targeted by repurposing FDA‐approved drugs.

Space WeatherEjections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters.

SpartanAnatomy.org: Evaluating a new interactive neuroradiology tool for early medical education
Anatomical Sciences Education, EarlyView.Abstract Teaching neuroanatomy through the lens of magnetic resonance imaging (MRI) offers medical students a strong foundation for success. However, many existing MRI learning resources lack interactivity and user‐friendliness, require payment, or include an overwhelming number of labeled structures.

Dynamics of coronal mass ejections [PDF]
Astronomy & Astrophysics, 2008 Context. Coronal and interplanetary propagation of coronal mass ejections (CMEs) is strongly affected by aerodynamic drag. Aims. The dependence of the drag acceleration on the mass of the CMEs is investigated to establish a quantitative empirical relationship, which might be important in semi-empirical space-weather forecasting. Methods.
