Assessing cerebral arterial pulse wave velocity using 4D flow MRI
Journal of Cerebral Blood Flow and Metabolism, 2021 Intracranial arterial stiffening is a potential early marker of emerging cerebrovascular dysfunction and could be mechanistically involved in disease processes detrimental to brain function via several pathways.

Pulse Wave Velocity in Postmenopausal Women [PDF]
Pulse, 2013 Cardiovascular disease (CVD) and osteoporosis are major causes of morbidity and mortality in postmenopausal women. The relationship between atherosclerosis and osteoporosis has been established by studies of the underlying pathophysiological mechanisms and biochemical pathways that seem to overlap in many places. Pulse wave velocity (PWV) is one of the

Does Estimated Pulse Wave Velocity Add Prognostic Information?
HYPERTENSION, 2020 Supplemental Digital Content is available in the text. The Reference Values for Arterial Stiffness Collaboration has derived an equation using age and mean blood pressure to estimated pulse wave velocity (ePWV), which predicted cardiovascular events ...

Hemodialysis Parameters and Pulse Wave Velocity
International Journal of Applied & Basic Medical Research, 2022 Abstract Aim: The study aimed to evaluate the acute effect of ultrafiltration on the mechanical properties of the aorta using brachial-ankle pulse wave velocity (PWV) before and after hemodialysis (HD). Patients and Methods: This study included 80 patients who were on a ...

Parametric Frequency Conversion of Short Optical Pulses Controlled by a CW Background [PDF]
, 2007 We predict that parametric sum-frequency generation of an ultra-short pulse may result from the mixing of an ultra-short optical pulse with a quasi-continuous wave control.

The velocity of pulse wave in man [PDF]
Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1922 In an investigation now being carried out by us at Manchester observations are being made, under various conditions, upon the velocity of the pulse wave in man. As a preliminary to this investigation it was thought advisable to study the theory of the transmission of the pulse wave, and the following pages contain the results arrived at, together with ...

Superluminal optical pulse propagation in nonlinear coherent media [PDF]
, 2002 The propagation of light-pulse with negative group-velocity in a nonlinear medium is studied theoretically. We show that the necessary conditions for these effects to be observable are realized in a three-level $\Lambda$-system interacting with a ...

A review of machine learning techniques in photoplethysmography for the non-invasive cuff-less measurement of blood pressure [PDF]
, 2020 Hypertension or high blood pressure is a leading cause of death throughout the world and a critical factor for increasing the risk of serious diseases, including cardiovascular diseases such as stroke and heart failure.
