Modeling Polarized Radio Sounding Observations of a Coronal Mass Ejection

The Astrophysical Journal
Coronal mass ejections (CMEs) evolve significantly as they propagate from the Sun to the Earth, so remote observations of their changes in speed, strength of the magnetic field, density, and overall structure are critical for predicting their arrival ...

Quantitative MRI Values for Atrial and Ventricular Parameters in Altitude‐Dwelling Youth

Journal of Magnetic Resonance Imaging, Volume 63, Issue 3, Page 828-845, March 2026.
ABSTRACT Background The hypoxic environment on the Qinghai Plateau significantly exacerbates myocardial remodeling, with sex/ethnicity‐specific variations in cardiac parameters among local youth. Current cardiac MRI reference values lack data from physiologically adapted populations on this plateau.

Identifying Coronal Mass Ejection Active Region Sources: An Automated Approach

The Astrophysical Journal
Identifying the source regions of coronal mass ejections (CMEs) is crucial for understanding their origins and improving space weather forecasting. We present an automated algorithm for matching CMEs detected by the Large Angle Spectrometric Coronagraph ...

Alcohol Septal Ablation in Hypertrophic Obstructive Cardiomyopathy: Long‐Term Follow‐Up of Deformations and Hemodynamics

Journal of Magnetic Resonance Imaging, Volume 63, Issue 3, Page 859-871, March 2026.
ABSTRACT Background A detailed evaluation of hemodynamics, supportive morphology, and deformation may help uncover the pathophysiology of hypertrophic obstructive cardiomyopathy (HOCM) and the changes wrought by alcohol septal ablation (ASA). Purpose To investigate the global cardiac volume, myocardial deformation, and hemodynamic characteristics ...

Understanding Interplanetary Coronal Mass Ejection Signatures

, 2006
While interplanetary coronal mass ejections (ICMEs) are understood to be the heliospheric counterparts of CMEs, with signatures undeniably linked to the CME process, the variability of these signatures and questions about mapping to observed CME features raise issues that remain on the cutting edge of ICME research.
