Relationship of Arterial Stiffness Index and Pulse Pressure With Cardiovascular Disease and Mortality

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2018
Vascular aging results in stiffer arteries and may have a role in the development of cardiovascular disease (CVD). Arterial stiffness index (ASI), measured by finger photoplethysmography, and pulse pressure (PP) are 2 independent vascular aging indices ...

Formation Principle and Characteristics of Self-Supercharging Pulsed Water Jet

Chinese Journal of Mechanical Engineering, 2022
High-pressure pulsed water jet technology has considerable development potential in the field of rock fragmentation. To overcome the shortcomings of existing pulsed jets, a self-supercharging pulsed water jet (SSPWJ) generation method is proposed, which ...

High frequency pressure oscillator for microcryocoolers [PDF]

, 2008
Microminiature pulse tube cryocoolers should operate at a frequency of an order higher than the conventional macro ones because the pulse tube cryocooler operating frequency scales inversely with the square of the pulse tube diameter.

On the Properties of Plastic Ablators in Laser-Driven Material Dynamics Experiments [PDF]

, 2007
Radiation hydrodynamics simulations were used to study the effect of plastic ablators in laser-driven shock experiments. The sensitivity to composition and equation of state was found to be 5-10% in ablation pressure.

Differences in ultrasound-derived arterial wall stiffness parameters and noninvasive blood pressure between Friesian horses and Warmblood horses [PDF]

, 2020
Background: Aortic rupture is more common in Friesians compared to Warmbloods, which might be related to differences in arterial wall composition and, as such, arterial wall stiffness (AWS).
