Influence of cavity lifetime on high-finesse microcavity two-photon absorption photodetectors [PDF]

, 2007
For optical pulse incidence as compared with continuous-wave incidence, the enhancement of two-photon absorption inside a high-finesse planar microcavity is reduced, the pulse inside the cavity and the cavity spectrum are broadened.

The Influence of Superpositional Wave Function Oscillations on Shor's Quantum Algorithm [PDF]

, 1999
We investigate the influence of superpositional wave function oscillations on the performance of Shor's quantum algorithm for factorization of integers. It is shown that the wave function oscillations can destroy the required quantum interference.

Analysis of the Radial Pulse Wave and its Clinical Applications: A Survey

IEEE Access, 2021
The arterial pulse wave is a physiological signal which can reflect the function of the human cardiovascular system. Owing to the measurement being convenient and safe, radial pulse waves have been often used in noninvasive monitoring of human health ...

Assessment of pulse rate variability by the method of pulse frequency demodulation

BioMedical Engineering OnLine, 2005
Background Due to its easy applicability, pulse wave has been proposed as a surrogate of electrocardiogram (ECG) for the analysis of heart rate variability (HRV). However, its smoother waveform precludes accurate measurement of pulse-to-pulse interval by

Comparison of arterial stiffness indices measured by pulse wave velocity and pulse wave analysis

Blood Pressure, 2019
Objective: Arterial stiffness indices measured by pulse wave velocity and pulse wave analysis have been widely studied in different populations. Only a few small studies have been reported regarding these two measurement methods.

Self-amplification of coherent spontaneous emission in a cherenkov free-electron maser [PDF]

, 2000
Ultrashort pulses of microwave radiation have been produced in a dielectric-lined Cherenkov free-electron maser (FEM) amplifier. An intense initial seed pulse, due to coherent spontaneous emission (CSE), arises at the leading edge of the electron pulse ...

Pulse wave response characteristics for thickness and hardness of the cover layer in pulse sensors to measure radial artery pulse

BioMedical Engineering OnLine, 2018
Background Piezo-resistive pressure sensors are widely used for measuring pulse waves of the radial artery. Pulse sensors are generally fabricated with a cover layer because pressure sensors without a cover layer are fragile when they come into direct ...
