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

open access: yes, 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.

Signal Separation Using a Mathematical Model of Physiological Signals for the Measurement of Heart Pulse Wave Propagation With Array Radar [PDF]

open access: yesIEEE Access (Early Access), 24 September 2020, 2020
The arterial pulse wave, which propagates along the artery, is an important indicator of various cardiovascular diseases. By measuring the displacement at multiple parts of the human body, pulse wave velocity can be estimated from the pulse transit time.

Elevated levels of urine isocitrate, hydroxymethylglutarate, and formiminoglutamate are associated with arterial stiffness in Korean adults

open access: yesScientific Reports, 2021
Recent evidence suggests that cellular perturbations play an important role in the pathogenesis of cardiovascular diseases. Therefore, we analyzed the association between the levels of urinary metabolites and arterial stiffness. Our cross-sectional study

Memory Effect of Gravitational Wave Pulses in PP-Wave Spacetimes [PDF]

open access: yesPhys. Scr. 99 (2024) 075023, 2023
In this paper, we study the gravitational memory effect in pp-wave spacetimes due to the passage of a pulse having the form of a ramp profile through this spacetime. We have analyzed the effect of this pulse on the evolution of nearby geodesics, and have determined analytical solutions of the geodesic equations in the Brinkmann coordinates.

Comparison of arterial stiffness indices measured by pulse wave velocity and pulse wave analysis

open access: yesBlood Pressure, 2019
Objective: Arterial stiffness indices measured by pulse wave velocity and pulse wave analysis have been widely studied in different populations. Only a few small studies have been reported regarding these two measurement methods.

Pulse Wave Velocity in Familial Combined Hyperlipidemia [PDF]

open access: yesAmerican Journal of Hypertension, 2007
In the present cross-sectional study we investigated whether familial combined hyperlipidemia (FCH) is associated with an increased arterial wall stiffness, and whether measures of arterial wall stiffness in FCH family members could contribute to cardiovascular risk stratification.Ninety-eight subjects with FCH and 230 unaffected relatives filled out a

Estimation of central pulse wave velocity from radial pulse wave analysis [PDF]

open access: yesComputer Methods and Programs in Biomedicine, 2022
Arterial stiffness, commonly assessed by carotid-femoral pulse wave velocity (cfPWV), is an independent biomarker for cardiovascular disease. The measurement of cfPWV, however, has been considered impractical for routine clinical application. Pulse wave analysis using a single pulse wave measurement in the radial artery is a convenient alternative ...

Observation of natural flexural pulse waves in retinal and carotid arteries for wall elasticity estimation [PDF]

open access: yes, 2023
The risk of cardiovascular events is linked to arterial elasticity that can be estimated from the pulse wave velocity. This symmetric wave velocity is related to the wall elasticity through the Moens-Korteweg equation.
