Matter wave interference using two-level atoms and resonant optical fields [PDF]

, 1998
A theory of matter wave interference is developed in which resonant optical fields interact with two-level atoms. When recoil effects are included, spatial modulation of the atomic density can occur for times that are greater than or comparable with the ...

Pulse wave analysis and pulse wave velocity techniques: are they ready for the clinic? [PDF]

Hypertension Research, 2010
interestingly describe animportant factor when arterial stiffness is clini-cally assessed: subject’s body position. Althoughthis is an important question, especially ifwe want to bring this research tool to the clinicin a regular basis, there are several other factorsthat should be considered.

Ionization waves of arbitrary velocity driven by a flying focus

, 2017
A chirped laser pulse focused by a chromatic lens exhibits a dynamic, or "flying," focus in which the trajectory of the peak intensity decouples from the group velocity.

Evaluation of Distensibility and Stiffness of Ascending Aortic Aneurysm using Magnetic Resonance Imaging

Journal of Nepal Medical Association, 2016
Introduction: Magnetic resonance imaging emerging as a new tool for the diagnosis and evaluation of ascending aortic aneurysm. The aim of our study is to evaluate in vivo distensibility and pulse wave velocity of the aortic wall using functional magnetic

Comparison between estimated and brachial‐ankle pulse wave velocity for cardiovascular and overall mortality prediction

The Journal of Clinical Hypertension, 2021
Pulse wave velocity (PWV) was a good marker of arterial stiffness and could predict cardiovascular (CV) outcomes. Recently, estimated PWV (ePWV) calculated by equations using age and mean blood pressure was reported to be an independent predictor of ...

The effect of creatine supplementation on the response of central and peripheral pulse wave velocity to high-intensity resistance exercise

Cogent Medicine, 2018
Following a bout of high-intensity resistance exercise, a transient increase in arterial stiffness, as measured through central pulse wave velocity has been shown to occur.
