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.

Coronal Mass Ejections and Coronal Structures [PDF]
, 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.

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.

Effect of an Interplanetary Coronal Mass Ejection on Saturn’s Radio Emission
Frontiers in Astronomy and Space Sciences, 2022 The Saturn Kilometric Radiation (SKR) was observed for the first time during the flyby of Saturn by the Voyager spacecraft in 1980. These radio emissions, in the range of a few kHz to 1 MHz, are emitted by electrons travelling around auroral magnetic ...

Additional acceleration of solar-wind particles in current sheets of the heliosphere [PDF]
, 2015 Particles of fast solar wind in the vicinity of the heliospheric current sheet (HCS) or in a front of interplanetary coronal mass ejections (ICMEs) often reveal very peculiar energy or velocity profiles, density distributions with double or triple peaks,

PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe
Advanced Science, EarlyView.This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.

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.

Current sheet formation and nonideal behavior at three-dimensional magnetic null points [PDF]
, 2007 The nature of the evolution of the magnetic field, and of current sheet formation, at three-dimensional (3D) magnetic null points is investigated. A kinematic example is presented that demonstrates that for certain evolutions of a 3D null (specifically ...
