Carrier-envelope phase dependence in single-cycle laser pulse propagation with the inclusion of counter-rotating terms

, 2012
We focus on the propagation properties of a single-cycle laser pulse through a two-level medium by numerically solving the full-wave Maxwell-Bloch equations.

Estimated pulse wave velocity and cardiovascular events in Chinese

International Journal of Cardiology. Hypertension, 2020
The estimated pulse-wave velocity (ePWV) as measure for arterial wall stiffness is associated with an increased risk of cardiovascular disease (CVDs) and all-cause death in Western populations.

In Vivo Pulse Wave Measurement Through a Multimode Fiber Diffuse Speckle Analysis System

Frontiers in Physics, 2021
Continuous monitoring of in vivo pulsatile blood flow and pulse wave velocity (PWV) is important for clinical applications. These parameters are correlated with physiological parameters, such as blood pressure and elasticity of blood vessels. A multimode

First SDO AIA Observations of a Global Coronal EUV "Wave": Multiple Components and "Ripples"

, 2012
We present the first SDO AIA observations of a global coronal EUV disturbance (so-called "EIT wave") revealed in unprecedented detail. The disturbance observed on 2010 April 8 exhibits two components: one diffuse pulse superimposed on which are multiple ...

Determinants of Brachial-Ankle Pulse Wave Velocity and Carotid-Femoral Pulse Wave Velocity in Healthy Koreans

Journal of Korean Medical Science, 2014
The aim of this study was to determine the normal value of brachial-ankle pulse wave velocity (baPWV) and carotid-femoral pulse wave velocity (cfPWV) according to age group, gender, and the presence of cardiovascular risk factors in healthy Koreans, and to investigate the association between PWV and risk factors such as prehypertension, dyslipidemia ...

A review of X-ray laser development at Rutherford Appleton Laboratory [PDF]

, 2002
Recent experiments undertaken at the Rutherford Appleton Laboratory to produce X-ray lasing over the 5-30 nm wavelength range are reviewed. The efficiency of lasing is optimized when the main pumping pulse interacts with a preformed plasma.

Validating tomographic model with broad-band waveform modelling: an example from the LA RISTRA transect in the southwestern United States [PDF]

, 2007
Traveltime tomographic models of the LA RISTRA transect produce excellent waveform fits if we amplify the damped images. We observe systematic waveform distortions across the western edge of the Great Plains from South American events, starting about 300

Pulmonary pulse wave velocity as assessed with velocity-encoded MRI [PDF]

Journal of Cardiovascular Magnetic Resonance, 2012
Pulmonary pulse wave velocity has proven to be an excellent indicator of pulmonary vascular wall stiffness. In this study a novel MRI method was evaluated, showing rapid assessment of pulmonary pulse wave velocity with excellent repeatability and observer reproducibility.
