Abnormal wave reflections and left ventricular hypertrophy late after coarctation of the aorta repair [PDF]

, 2017
Patients with repaired coarctation of the aorta are thought to have increased afterload due to abnormalities in vessel structure and function. We have developed a novel cardiovascular magnetic resonance protocol that allows assessment of central ...

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 ...

Optical tsunamis: shoaling of shallow water rogue waves in nonlinear fibers with normal dispersion [PDF]

, 2013
In analogy with ocean waves running up towards the beach, shoaling of prechirped optical pulses may occur in the normal group-velocity dispersion regime of optical fibers. We present exact Riemann wave solutions of the optical shallow water equations and

Ionization waves of arbitrary velocity driven by a flying focus

, 2017
A chirped laser pulse focused by a chromatic lens exhibits a dynamic, or "flying," focus in which the trajectory of the peak intensity decouples from the group velocity.
