Laser Doppler technology applied to atmospheric environmental operating problems [PDF]

open access: yes
Carbon dioxide laser Doppler ground wind data were very favorably compared with data from standard anemometers. As a result of these measurements, two breadboard systems were developed for taking research data: a continuous wave velocimeter and a pulsed ...

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

open access: yesAdvanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Radial capacity and hemodynamics evaluation in vitro and implantable feasibility validation in vivo of thinner bioresorbable polymer vascular stents

open access: yesBMEMat, EarlyView.
A series of in vitro experiments, numerical simulations and in vivo experiments were conducted to jointly evaluate the effects of different thicknesses of bioabsorbable polymer vascular stents on their radial capacity, hemodynamics and in vivo outcomes.

Pulsed and continuous wave doppler in heart lesions

open access: yesArchives of Acoustics, 2015
Valvular obstructions and regurgitations can be diagnosed with either pulsed or CW Doppler. By recording the maximum velocities with CW Doppler the pressure drop across obstructions and across regurgitant valves can be obtained, permitting assessment of ...

Effect of Dispersed Particle Concentration on Photoacoustic Flowmetry Using Low-Frequency Transducers

open access: yesMetrology
Photoacoustic (PA) velocimetry offers a promising solution to the limitations of conventional techniques for measuring blood flow velocity. Given its moderate penetration depth and high spatial resolution, PA imaging is considered suitable for measuring ...

Electric fields in plasmas under pulsed currents

open access: yes, 2007
Electric fields in a plasma that conducts a high-current pulse are measured as a function of time and space. The experiment is performed using a coaxial configuration, in which a current rising to 160 kA in 100 ns is conducted through a plasma that ...

Lean ZSF1 rats in basic research on heart failure with preserved ejection fraction

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1474-1478, April 2025.
Abstract Aims ZSF1 obese rats harbouring two mutant leptin receptor alleles (Leprcp and Leprfa) develop metabolic syndrome and heart failure with preserved ejection fraction (HFpEF), making them a widely used animal model in cardiometabolic research.
