Flexural pulse wave velocity in blood vessels

open access: yesThe Journal of the Acoustical Society of America
Arteriosclerosis is a major risk factor for cardiovascular disease and results in arterial vessel stiffening. Velocity estimation of the pulse wave sent by the heart and propagating into the arteries is a widely accepted biomarker. This symmetrical pulse wave propagates at a speed which is related to the Young's modulus through the Moens Korteweg (MK ...

Structured Multilayer Thin Films for Catalytic Applications: A Novel Approach on Catalyst Design Utilizing Microfabrication Techniques

open access: yesAdvanced Functional Materials, EarlyView.
A structured multilayer catalyst is fabricated by combining RF magnetron sputtering and picosecond laser scribing to expose Cu–ZnO interfaces. This model catalyst, developed as a proof of concept, enables precise interface accessibility for CO2 hydrogenation to methanol.

The Scintillation Velocity of the Relativistic Binary Pulsar PSR J1141-6545

open access: yes, 2002
We report a dramatic orbital modulation in the scintillation timescale of the relativistic binary pulsar J1141--6545 that both confirms the validity of the scintillation speed methodology and enables us to derive important physical parameters.

PULSE WAVE VELOCITY DETERMINANTS IN CHILDREN

open access: yesJournal of Hypertension, 2019
Objective:Arterial stiffness, measured by pulse wave velocity, is an independent predictor of cardiovascular events and mortality in adults. Recent studies have demonstrated an association between higher levels of blood pressure in youth and adverse changes in measures of vascular structure and ...

Pulse Wave Velocity Predicts Response to Renal Denervation in Isolated Systolic Hypertension

open access: yesJournal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2017
Background Renal sympathetic denervation seems to be less effective as a treatment for hypertension in patients with isolated systolic hypertension, a condition associated with elevated central arterial stiffness.

Reconfigurable 3D Magnetic Nanoarchitectures

open access: yesAdvanced Functional Materials, EarlyView.
This experimental study confirms that 3D magnetic tetrapods grown by focused electron beam‐induced deposition exhibit sequential, controllable magnetization reversal in the individual nanowire legs. The magnetic state of the nanoarchitecture can be controlled individually, on‐demand, through a variation of the direction and magnitude of the applied ...

Nonlinear surface waves in left-handed materials

open access: yes, 2003
We study both linear and nonlinear surface waves localized at the interface separating a left-handed medium (i.e. the medium with both negative dielectric permittivity and negative magnetic permeability) and a conventional (or right-handed) dielectric ...
