Deflected propagation of a coronal mass ejection from the corona to interplanetary space [PDF]

open access: yes, 2014
Among various factors affecting the space weather effects of a coronal mass ejection (CME), its propagation trajectory in the interplanetary space is an important one determining whether and when the CME will hit the Earth.

Coronal Mass Ejections and Coronal Structures [PDF]

open access: yes, 1989
The coronal portion of the solar atmosphere consists of a wide variety of structures which exhibit a similarly wide variety of dynamical processes and kinds of activity. The launch of the SMM presented an opportunity to study the low and intermediate corona from space with multiple instruments for protracted periods of time.

Initiation of Coronal Mass Ejections by Sunspot Rotation [PDF]

open access: yesSolar Physics, 2013
AbstractWe report observations of a filament eruption, two-ribbon flare, and coronal mass ejection (CME) that occurred in Active Region NOAA 10898 on 6 July 2006. The filament was located South of a strong sunspot that dominated the region. In the evolution leading up to the eruption, and for some time after it, a counter-clockwise rotation of the ...

A Coronal Mass Ejection Source Region Catalog and Their Associated Properties

open access: yesThe Astrophysical Journal Supplement Series, 2023
The primary objective of this study is to connect coronal mass ejections (CMEs) to their source regions, primarily to create a CME source region catalog, and secondarily to probe the influence that the source regions have on the different statistical ...

A SOLAR TYPE II RADIO BURST FROM CORONAL MASS EJECTION–CORONAL RAY INTERACTION: SIMULTANEOUS RADIO AND EXTREME ULTRAVIOLET IMAGING [PDF]

open access: yes, 2014
Simultaneous radio and extreme ultraviolet (EUV)/white-light imaging data are examined for a solar type II radio burst occurring on 2010 March 18 to deduce its source location. Using a bow-shock model, we reconstruct the three-dimensional EUV wave front (

Solar Coronal Mass Ejection and Post–Coronal Mass Ejection Blob Formation in Two-fluid Simulations

open access: yesThe Astrophysical Journal
A 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.

Rapamycin Alleviates Heart Failure Caused by Mitochondrial Dysfunction and SERCA Hypoactivity in Syntaxin 12/13 Deficient Models

open access: yesAdvanced Science, EarlyView.
Rapamycin alleviates heart failure via TFEB and CaMKII pathways in Syntaxin 12/13 deficient models. Stx12 deficiency causes heart failure via impaired iron trafficking to mitochondria, reducing respiratory complexes and sarcoplasmic reticulum Ca2+‐ATPase (SERCA).

CAMEL. II. A 3D Coronal Mass Ejection Catalog Based on Coronal Mass Ejection Automatic Detection with Deep Learning

open access: yesThe Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are major drivers of geomagnetic storms, which may cause severe space weather effects. Automating the detection, tracking, and three-dimensional (3D) reconstruction of CMEs is important for operational predictions of CME ...

Magnetically Controllable and Degradable Milliscale Swimmers as Intraocular Drug Implants

open access: yesAdvanced Science, EarlyView.
Magnetically controllable degradable milliscale swimmers (MDMS) offer a promising alternative to commercial intraocular drug implants, reducing complications like implant dislocation and uncontrolled drug release. MDMS achieve high velocities in ocular environments, enable real‐time imaging, and deliver drugs effectively without disrupting retinal ...

DIRECT OBSERVATIONS OF MAGNETIC FLUX ROPE FORMATION DURING A SOLAR CORONAL MASS EJECTION [PDF]

open access: yes, 2014
Coronal mass ejections (CMEs) are the most spectacular eruptive phenomena in the solar atmosphere. It is generally accepted that CMEs are the results of eruptions of magnetic flux ropes (MFRs).
