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]
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.

Impact of Treatment With Protease Inhibitors on Aortic Stiffness in Adult Patients With Human Immunodeficiency Virus Infection [PDF]
Background— The role of antiretroviral therapy in acceleration of atherosclerosis in patients with human immunodeficiency virus (HIV) infection is controversial.

Pulse wave velocity (PWV) was a good marker of arterial stiffness and could predict cardiovascular (CV) outcomes. Recently, estimated PWV (ePWV) calculated by equations using age and mean blood pressure was reported to be an independent predictor of ...

Effects of beam velocity and density on an ion-beam pulse moving in magnetized plasmas [PDF]
The wakefield and stopping power of an ion-beam pulse moving in magnetized plasmas are investigated by particle-in-cell (PIC) simulations. The effects of beam velocity and density on the wake and stopping power are discussed. In the presence of magnetic field, it is found that beside the longitudinal conversed V-shaped wakes, the strong whistler wave ...

Are "EIT Waves" Fast-Mode MHD Waves? [PDF]
We examine the nature of large-scale, coronal, propagating wave fronts (``EIT waves'') and find they are incongruous with solutions using fast-mode MHD plane-wave theory. Specifically, we consider the following properties: non-dispersive single pulse manifestions, observed velocities below the local Alfven speed, and different pulses which travel at ...

The effects of antihypertensive drugs on arterial stiffness☆
Ageing and cardiovascular risk factors, particularly uncontrolled hypertension, adversely impact arterial stiffness and wave reflection leading to increased central systolic blood pressure.

Spatially multiplexed picosecond pulse-train generations through simultaneous intra-modal four wave mixing and inter-modal cross-phase modulation [PDF]
We report on the experimental generation of spatially multiplexed picosecond 40-GHz pulse trains at telecommunication wavelengths by simultaneous intra-modal multiple four wave mixing and intermodal cross-phase modulation in km-long bi-modal and 6-LP-mode graded-index few-mode fibers. More precisely, an initial beat-signal injected into the fundamental
