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 ...

Validity and reproducibility of arterial pulse wave velocity measurement using new device with oscillometric technique: A pilot study

BioMedical Engineering OnLine, 2005
Background Availability of a range of techniques and devices allow measurement of many variables related to the stiffness of large or medium sized arteries. There is good evidence that, pulse wave velocity is a relatively simple measurement and is a good

Novel Methods for Pulse Wave Velocity Measurement [PDF]

Journal of Medical and Biological Engineering, 2015
The great incidence of cardiovascular (CV) diseases in the world spurs the search for new solutions to enable an early detection of pathological processes and provides more precise diagnosis based in multi-parameters assessment. The pulse wave velocity (PWV) is considered one of the most important clinical parameters for evaluate the CV risk, vascular ...

Insulin-resistance HCV infection-related affects vascular stiffness in normotensives [PDF]

, 2015
Background and Aims. Arterial stiffness evaluated as pulse wave velocity, is an early marker of vascular damage and an independent predictor for cardiovascular events.

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

Computer 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 ...

P6.01 IMPLANTABLE PULSE WAVE VELOCITY SENSOR

Artery Research, 2013
In case of vascular weakness or thrombosis stents are implanted and brace vessels from the inside to assure the proper blood flow. A widespread method to monitor the state of blood vessels in terms of their stiffness and diameter is to measure the pulse ...

Arterial stiffening acts synergistically with APOE genotype and AD biomarker status to influence memory in older adults without dementia

Alzheimer’s Research & Therapy, 2021
Background Arterial stiffening has emerged as an important risk factor for Alzheimer’s disease (AD) and related dementias. Carotid-femoral pulse wave velocity has been proposed as a non-invasive and reproducible method to assess arterial stiffness ...

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.
