One of the interesting Laser-Plasma phenomena, when the laser power is high and ultra intense, is the generation of large amplitude plasma waves (Wakefield) and electron acceleration. An intense electromagnetic laser pulse can create plasma oscillations through the action of the nonlinear pondermotive force. electrons trapped in the wake can be accelerated to high energies, more than 1 TW. Of t...

Background: The relationship between serum homocysteine levels and cardiovascular diseases has been elucidated since many years ago. In this study, the association between serum levels of homocysteine, folic acid, and vitamin B12 with the pulse wave velocity and Buckberg index or subendocardial viability ratio was assessed in individuals with diabetes and also non-diabetic subjects. Metho...

We wish to model pulse wave velocity (PWV) as a function of longitudinal measurements of pulse pressure (PP) at the same and prior visits at which the PWV is measured. A number of approaches are compared. First, we use the PP at the same visit as the PWV in a linear regression model. In addition, we also use the average of all available PP's as the explanatory variable in a linear regression mo...

BACKGROUND Systolic blood pressure and pulse pressure are substantially higher in older adults. The relative contributions of increased forward versus reflected pressure wave amplitude or earlier arrival of the reflected wave to elevated pulse pressure remain controversial. METHODS AND RESULTS We measured proximal aortic pressure and flow, forward pressure wave amplitude, global wave reflecti...

The findings of Nadi Vijnana of 53 asymptomatic adult males were compared with the results of the blood examinations and the radial pulse pressure wave analysis conducted concomitantly. K pulse had elongated fatty pulse wave contour which is opposite to the slime V one, on the other hand, P pulse had the vibratory contour as the basic principles of Ayurveda. K pulse or K/P pulse had the largest...

OBJECTIVES Recently, echo-tracking-derived measures of arterial stiffness have been introduced in clinical practice for the assessment of one-point pulse wave velocity. The purpose of this study was to find a relation between carotid-femoral pulse wave velocity and one-point carotid pulse wave velocity, and to find a value of one-point carotid pulse wave velocity that predicts carotid-femoral p...
