Matched Pulse Propagation in a Three-Level System

, 1997
The B\"{a}cklund transformation for the three-level Maxwell-Bloch equation is presented in the matrix potential formalism. By applying the B\"{a}cklund transformation to a constant electric field background, we obtain a general solution for matched ...

The effect of creatine supplementation on the response of central and peripheral pulse wave velocity to high-intensity resistance exercise

Cogent Medicine, 2018
Following a bout of high-intensity resistance exercise, a transient increase in arterial stiffness, as measured through central pulse wave velocity has been shown to occur.

Velocity selector with a microwave magnetic dipole transition

, 2014
We proposed a method based on microwave magnetic dipole transitions to prepare samples of atoms with well defined position and velocity. Each microwave pulse corresponds to a position measurement for the atoms and two pulses separated by a given delay ...

Hawking radiation from "phase horizons" in laser filaments?

, 2012
Belgiorno et al have reported on experiments aiming at the detection of (the analogue of) Hawking radiation using laser filaments [F. Belgiorno et al, Phys. Rev. Lett. 105, 203901 (2010)].

Attenuation law of MWD pulses in aerated drilling

Petroleum Exploration and Development, 2012
A mathematical model for predicting the attenuation of measurement while drilling (MWD) pressure pulses in aerated drilling was proposed using the two-phase flow model and considering the momentum and energy exchange at the phase interface, gravity of ...

Using Support Vector Machine to Improve Ultrasonic Pulse Velocity Test for Concrete

MATEC Web of Conferences, 2018
In the construction industry, to evaluate the compressive strength of concrete, destructive and non-destructive testing methods are used. Non-destructive testing methods are preferable due to the fact that those methods do not destroy concrete samples ...

Acute changes in indices of cardiac filling and function induced by high-dose intravenous methylprednisolone pulse therapy: a single-center prospective study

Immunological Medicine
The current study investigated acute circulatory dynamics changes induced by high-dose intravenous methylprednisolone pulse therapy (steroid pulse therapy). Eight patients who underwent steroid pulse therapy were included in the study.
