Universal Approach to Optimal Photon Storage in Atomic Media [PDF]

, 2007
We present a universal physical picture for describing storage and retrieval of photon wave packets in a Lambda-type atomic medium. This physical picture encompasses a variety of different approaches to pulse storage ranging from adiabatic reduction of ...

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 ...

Do higher dialysate calcium concentrations increase vascular stiffness in haemodialysis patients as measured by aortic pulse wave velocity? [PDF]

, 2013
Background: Haemodialysis patients have an increased prevalence of hypertension and risk of cardiovascular mortality and stroke. Higher dialysate calcium concentrations have been reported to cause both an acute and chronic increase in arterial ...

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.
