First Results from the Thomson Scattering Diagnostic on the Large Plasma Device

open access: yesInstruments, 2022
We present the first Thomson scattering measurements of electron density and temperature in the Large Plasma Device (LAPD), a 22 m long magnetized linear plasma device at the University of California Los Angeles (UCLA). The diagnostic spectrally resolves

Flow field and local burning velocity affected by stretch in swirl flow of turbulent premixed flames

open access: yesJournal of Thermal Science and Technology, 2022
In this study, we have investigated turbulent premixed flames affected by local stretch in a swirl flow, measured by the simultaneous OH-PLIF/SPIV system. Evaluating the transient of burning velocity and stretch rate, the flow and the flame dynamics in a

Two-Dimensional Thomson Scattering in Laser-Produced Plasmas

open access: yesInstruments, 2023
We present two-dimensional (2D) optical Thomson scattering measurements of electron density and temperature in laser-produced plasmas. The novel instrument directly measures ne(x,y) and Te(x,y) in two dimensions over large spatial regions (cm2) with sub ...

Can Photobiomodulation Therapy Using an 810-nm Diode Laser Increase the Secondary Stability of Orthodontic Mini-Screws? A Split-Mouth Double-Blind Randomized Clinical Trial

open access: yesApplied Sciences, 2023
Background: In orthodontic treatment, mini-screws can provide maximum anchorage conditions. If the miniscrew stability is compromised, this could jeopardize the outcomes of the orthodontic treatment or biomechanics.

Incoherent Thomson scattering: future implementation and measurement capabilities on the PANDORA experiment

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The PANDORA (Plasmas for Astrophysics Nuclear Decays Observation and Radiation for Archaeometry) experiment aims to study the β-decay process inside a dense plasma mimicking stellar conditions. An electron cyclotron resonance plasma trap will be built at

Evaluation of Vaporizing Diesel Spray with High-Speed Laser Absorption Scattering Technique for Measuring Vapor and Liquid Phase Concentration Distributions

open access: yesFuels, 2023
The Conventional Laser Absorption Scattering (C-LAS) technique is used to measure the mixture concentration and visualize the vapor phase. The former is determined by the attenuation of visible and ultraviolet light whereas the latter is achieved via ...

Photodynamic Therapy of Breast Cancer in Animal Models and Their Potential Use in Clinical Trials—Role of the Photosensitizers: A Review

open access: yesFrontiers in Bioscience-Landmark, 2023
In this article, we reviewed the use of photodynamic therapy (PDT) for breast cancer (BC) in animal models. These in vivo models imitate the cancer disease progression, aid diagnosis, as well as create opportunities to assess treatment during the ...
