Causal relationships between eruptive prominences and coronal mass ejections [PDF]
A close association between eruptive prominences and CMEs, both slow and fast CMEs, was reported in many studies. Sometimes it was possible to follow the material motion starting from the prominence (filament) activation to the CME in the high corona.

Accurate Hugoniots and sound velocities of bismuth under shock compression in the 38-100 GPa range
Dynamic compression experiments of bismuth (Bi) in a shock pressure range of 38-100 GPa were conducted using an explosive drive. The time-resolved particle velocity profiles at the Bi/LiF (lithium fluoride) interface and the impact velocities were ...

The effect of recanalization of a chronic total coronary occlusion on P-wave dispersion [PDF]
Introduction: P-wave dispersion (PWD) obtained from the standard 12-lead electrocardiography (ECG) is considered to reflect the homogeneity of the atrial electrical activity.

Simulated Obstructive Sleep Apnea Increases P-Wave Duration and P-Wave Dispersion. [PDF]
BACKGROUND:A high P-wave duration and dispersion (Pd) have been reported to be a prognostic factor for the occurrence of paroxysmal atrial fibrillation (PAF), a condition linked to obstructive sleep apnea (OSA).

The P wave dispersion—one pixel, one millisecond
The electrophysiological activity of the heart is recorded and presented in form of electrocardiogram (ECG). In 1998 the concept of P wave dispersion as the risk factor for atrial fibrillation (AF) recurrence was introduced.

P wave dispersion and maximum P wave duration are independently associated with rapid renal function decline. [PDF]
The P wave parameters measured by 12-lead electrocardiogram (ECG) are commonly used as noninvasive tools to assess for left atrial enlargement. There are limited studies to evaluate whether P wave parameters are independently associated with decline in ...
