The dynamics of a nanosecond discharge with an extended hollow cathode in argon is studied and the electron energy distribution function (EEDF) plasma column calculated. issues formation EEDF inside cavity are considered. conditions validity two-term approximation analyzed appropriate evaluations given. Keywords: cathode, pulse discharge, argon, function.

Background: Pulse Oximeter monitoring has become so common over previous decades that in some health care units, blood oxygen level is now considered as the fifth vital sign. However, it seems there is still some lack of knowledge and/or experience among medical staff operating pulse oximeter and interpreting its results. The aim of this study was to investigate and compare the knowledge on Pul...

Broadband supercontinuum spectra are generated in a microstructured fiber using femtosecond laser pulses. Noise properties of these spectra are studied through experiments and numerical simulations based on a generalized stochastic nonlinear Schrödinger equation. In particular, the relative intensity noise as a function of wavelength across the supercontinuum is measured over a wide range of in...

Traditional stepped frequency chirp pulse train methods suffer from high sidelobes and ambiguous peaks, known as grating lobes and difficulty in compensating Doppler effect caused by target motion. This paper investigates a class of non-linear stepped frequency chirp pulse train with low sidelobes and capability to cancel clutter and to compensate motion. We present analytic expression for its ...

This project proposes a pulse analysis system for doctors to diagnose their patients using their pulse signals. A novice and easy time-domain algorithm is applied to pulse signal for periodic function examination. Monitoring and modeling our body as a system with digitalized pulse signals is one of the linkages that we can find among Traditional Chinese Medicine (TCM), hemodynamics and modern I...

In subjects with renal disease, reduced renal function and increased arterial stiffness are significantly associated in cross-sectional studies. The relationship is independent of age, blood pressure (BP), and atherosclerosis. Because both variables are independent predictors of cardiovascular risk, time-dependent relationships between them are important to determine. Aortic pulse wave velocity...

introduction blood pressure (bp) is one of the important vital signs that need to be monitored for personal healthcare. arterial blood pressure is estimated from pulse transit time (ptt). this study uses two pulse sensors to get ptt. the aim of this study was to construct an optical system and to monitor blood pressure continuously and without cuff in people with different ages. materials and m...

medical environments such as hospital waiting rooms can affect a client’s anxiety level as wellas psychological and physiological responses to his or her situation. the aim of this research was to evaluatethe use of environmental design, specifically the design which incorporates elements of nature, in clinics andhospitals to decrease anxiety, blood pressure and pulse rates of waiting clients. ...

Abstract We study the photon statistics of weak coherent pulses propagating through a cold atomic ensemble in regime Rydberg electromagnetically induced transparency. show experimentally that value second-order autocorrelation function transmitted light strongly depends on position within pulse and heavily varies during transients pulse. In particular, we falling edge displays much lower values...

Ultrafast magnetization switching induced by a single femtosecond laser pulse, under no applied magnetic field has attracted lot of attention in the last 10 years because its high potential for low-energy and ultrafast memory applications. Single-pulse helicity-independent mostly been demonstrated $\mathrm{Gd}$-based materials. It is now necessary to optimize pulse duration energy needed switch...
