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 ...

Current Helicity in Response to Coronal Mass Ejections
The Astrophysical JournalCoronal mass ejections (CMEs), powerful solar eruptions with massive plasma ejected into the interplanetary space, are caused by the release of the magnetic free energy stored in coronal electric currents.

Evidence linking coronal mass ejections with interplanetary magnetic clouds [PDF]
Using proxy data for the occurrence of those mass ejections from the solar corona which are directed earthward, we investigate the association between the post-1970 interplanetary magnetic clouds of Klein and Burlaga and coronal mass ejections.

Testing the Empirical Shock Arrival Model using Quadrature Observations
, 2013 The empirical shock arrival (ESA) model was developed based on quadrature data from Helios (in-situ) and P-78 (remote-sensing) to predict the Sun-Earth travel time of coronal mass ejections (CMEs) [Gopalswamy et al. 2005a].

Solar Mass Ejections and Coronal Holes [PDF]
International Astronomical Union Colloquium, 1996 AbstractIn this paper we present observations of two types of solar mass ejections, which seem to be associated with the location of coronal holes. In the first type, a filament eruption was observed near a coronal hole, which gave rise to a strong interplanetary scintillations, as detected by IPS observations.

Fully Automated Plane Prescription in Cardiac MRI: A Prospective Cohort Study
Journal of Magnetic Resonance Imaging, Volume 63, Issue 3, Page 891-903, March 2026.ABSTRACT Background Accurate plane positioning is important for high‐quality cardiac MRI images but requires specialized training, limiting accessibility. Purpose To evaluate an automated plane positioning tool and compare it with manual planning. Study Type Prospective.

The dynamics of eruptive prominences
, 2014 This chapter discusses the dynamical properties of eruptive prominences in relation to coronal mass ejections (CMEs). The fact that eruptive prominences are a part of CMEs is emphasized in terms of their physical association and kinematics. The continued

Martian Atmospheric Loss Through Foreshock Transient Events
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract At Mars, the MAVEN spacecraft has made observations of Hot Flow Anomalies (HFAs) in the foreshock. Due to the bow shock's proximity to the planet, it is theorized that HFAs contribute to atmospheric escape at Mars through the excavation of ionospheric ions.

Micro-Sigmoids as Progenitors of Coronal Jets - Is Eruptive Activity Self-Similarly Multi-Scaled?
, 2010 Observations from the X-ray telescope (XRT) on Hinode are used to study the nature of X-ray bright points, sources of coronal jets. Several jet events in the coronal holes are found to erupt from small-scale, S-shaped bright regions.
