Case Report of a Giant Mediastinal Neurofibroma Misdiagnosed as Massive Pleural Effusion. [PDF]
Clin Case RepABSTRACT Mediastinal neurogenic tumors are benign neoplasms commonly found along nerves in the posterior mediastinum, with rare malignant transformation. We report a case of a 36‐year‐old woman admitted to the respiratory department with complaints of chest tightness, cough, and sputum production.

Proton beam velocity distributions in an interplanetary coronal mass ejection [PDF]
Annales Geophysicae, 2009 The plasma and magnetic-field instruments on the Helios 2 spacecraft, which was on 3 April 1979 located at 0.68 AU, detected an interplanetary coronal mass ejection (ICME) that revealed itself by the typical signature of magnetic field rotation.

Planar magnetic structures in coronal mass ejection-driven sheath regions [PDF]
Annales Geophysicae, 2016 Planar magnetic structures (PMSs) are periods in the solar wind during which interplanetary magnetic field vectors are nearly parallel to a single plane.

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 Ejection Image Edge Detection In Heliospheric Imager STEREO SECCHI Data
The Open Journal of Astrophysics, 2022 We present an algorithm to detect the outer edges of Coronal Mass Ejection (CME) events as seen in differences of Heliospheric Imager STEREO SECCHI HI-1 images from either A or B spacecraft, as well as its implementation in Python.

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.

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 ...

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.
