In this paper, we present various theoretical models that accurately approximate the spectral density of the optical capture cross-section (σe0) obtained through the analysis of photo-capacitance transients using the deep-level optical spectroscopy

Results of a deep-level transient spectroscopy (DLTS) study of trapping states in Ni/Au Schottky diodes made on Si-doped GaN layers grown by metal–organic vapor-phase epitaxy (MOVPE) on highly conductive n-type Ammono-GaN substrates are reported. I

Objective Carotid-femoral pulse wave velocity (PWV) has been shown to be a powerful predictor of cardiovascular morbidity and mortality. Sympathetic neural mechanisms may have a stiffening influence on arterial mechanical properties. The relationship

Publikováno v: Journal of Hypertension. 18:437-444

Although headache is regarded a symptom of hypertension, its relation to blood pressure, especially in mild and moderate hypertension, is not clear. Thus, the aim of the study was to investigate whether headache in patients with mild to moderate hype

Duration, frequency, and temporal distribution of attacks have been objectively estimated in 11 SUNCT patients (3 women and 8 men). The mean age at the time of the study was 69 years (range 52 to 81). The duration of a total of 348 attacks was measur
