Urbanization as a risk factor for aortic stiffness in a cohort in India. [PDF]

PLoS ONE, 2018
Urbanization is associated with higher prevalence of cardiovascular disease worldwide. Aortic stiffness, as measured by carotid-femoral pulse wave velocity is a validated predictor of cardiovascular disease. Our objective was to determine the association

A learning-based image processing approach for pulse wave velocity estimation using spectrogram from peripheral pulse wave signals: An in silico study

Frontiers in Physiology, 2023
Carotid-to-femoral pulse wave velocity (cf-PWV) is considered a critical index to evaluate arterial stiffness. For this reason, estimating Carotid-to-femoral pulse wave velocity (cf-PWV) is essential for diagnosing and analyzing different cardiovascular ...

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 ...

Influence of Blood Compressibility on Pulse Wave Propagation Properties Based on Elastic Thin-Walled Tube Theory

Physical Activity and Health, 2023
Pulse wave carries abundant physiological and pathological data about the human body. Understanding the effect of blood compressibility on the transmission qualities of pulse waves is necessary to detect, cure, and prevent cardiovascular problems.

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.

Ambulatory Pulse Wave Velocity Monitoring [PDF]

Hypertension, 2017
See related article, pp 148–157 The role of office and ambulatory 24-hour measurement of brachial blood pressure (BP) on the assessment and prediction of cardiovascular risk and mortality has been well established. In addition, the independent predictive value of office measurement of carotid-to-femoral pulse wave velocity (PWV), a surrogate of ...

Possibilities of using the ultrasonic wave transmission method to estimate initial setting time of cement paste [PDF]

, 2008
In this paper, the applicability of the ultrasonic wave transmission method to estimate the initial setting time of an arbitrary cement paste is discussed. Ultrasonic pulse velocity measurements were fully automated and measured continuously.

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 ...
