Dynamic Matter-Wave Pulse Shaping [PDF]
Physical Review A, 2010 In this paper we discuss possibilities to manipulate a matter-wave with time-dependent potentials. Assuming a specific setup on an atom chip, we explore how one can focus, accelerate, reflect, and stop an atomic wave packet, with, for example, electric ...

Pulse Wave Velocity in Atherosclerosis [PDF]
Frontiers in Cardiovascular Medicine, 2019 Early detection of subclinical atherosclerosis is important to reduce patients' cardiovascular risk. However, current diagnostic strategy focusing on traditional risk factors or using risk scoring is not satisfactory. Non-invasive imaging tools also have

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 ...

Venous pulse wave velocity [PDF]
Vascular Pharmacology, 2020 Central venous pressure and volume status are relevant parameters for the characterization of the patient's haemodynamic condition and for the management of fluid therapy however, their invasive assessment is affected by various risks and complications while non-invasive approaches provide only imprecise and subjective indications.

British Journal of Clinical Pharmacology, 2001 ‘Since the information which the pulse affords is of so great importance, and so often consulted, surely it must be to our advantage to appreciate fully all it tells us, and to draw from it every detail that it is capable of imparting’ F.A. Mahomed 1872 [1] It is now possible to generate the ascending aortic pressure wave from the arterial pressure ...

Hypertension, 2011 Cardiovascular refers to the Cardio (heart) and vascular (blood vessels). The system has two major functional parts: central circulation system and systemic circulation system. Central circulation includes the pulmonary circulation and the heart from where the pulse wave is generated. Systemic circulation is the path that the blood goes from and to the

Gravitational wave pulse and soliton wave collision [PDF]
Physical Review D, 1987 We study the collision of a gravitational wave pulse and a soliton wave on a spatially homogeneous background. This collision is described by an exact solution of Einsteins equations in a vacuum which is generated from a nondiagonal seed by means of a soliton transformation.

Physiological Reports, 2021 We hypothesized that volume changes during 48‐h are associated with different circadian patterns of arterial stiffness on non‐dialysis day compared to dialysis day and that the night‐time increase of arterial stiffness is associated with higher mortality.

Circulation Research, 1981 This report evaluates pulse wave propagation with respect to contributions by vascular wall elastic and geometric properties, vessel wall and blood viscosity, and nonlinearities in system parameters and in the equations of motion. Discrepancies in results obtained with different experimental methods and theory are discussed and resolved.
