Mirror-mode Structures in Coronal Mass Ejection Sheaths

The Astrophysical Journal
Coronal mass ejections (CMEs) compress the upstream solar wind as they travel through interplanetary space, forming sheath regions and preceding shocks rich in plasma dynamics.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, EarlyView.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

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.

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.

STEREO and Wind observations of a fast ICME flank triggering a prolonged geomagnetic storm on 5-7 April 2010

, 2010
On 5 April 2010 an interplanetary (IP) shock was detected by the Wind spacecraft ahead of Earth, followed by a fast (average speed 650 km/s) IP coronal mass ejection (ICME).

Left Ventricular Outflow Tract Geometry as a Predictor of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation Using the Evolut Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM

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 ...

Relating near-Earth observations of an interplanetary coronal mass ejection to the conditions at its site of origin in the solar corona [PDF]

, 2005
A halo coronal mass ejection (CME) was detected on January 20, 2004. We use solar remote sensing data (SOHO, Culgoora) and near-Earth in situ data (Cluster) to identify the CME source event and show that it was a long duration flare in which a magnetic ...

Unexpected Giant Right Coronary Artery Aneurysm Diagnosed by Computed Tomography Angiography in the Emergency Department

Journal of Clinical Ultrasound, EarlyView.
3D Volume Rendering coronary CTA reconstruction showing a giant thrombosed aneurysm of the proximal right coronary artery ABSTRACT Giant coronary artery aneurysms (GCAA) are usually defined as diameter > 8 mm or > 400% of the adjacent normal segment; they are very rare (reported prevalence ≈0.02%).
