Interdependencies between acoustic and high-speed videoendoscopy parameters.

PLoS ONE, 2021
In voice research, uncovering relations between the oscillating vocal folds, being the sound source of phonation, and the resulting perceived acoustic signal are of great interest.

Which Parameters Affect Biofilm Removal with Acoustic Cavitation? A Review.

Ultrasound in Medicine and Biology, 2019
Bacterial biofilms are a cause of contamination in a wide range of medical and biological areas. Ultrasound is a mechanical energy that can remove these biofilms using cavitation and acoustic streaming, which generate shear forces to disrupt biofilm from

Acoustic radiation from a pulsating spherical cap set on a spherical baffle near a hard/soft flat surface

, 2004
Radiation of sound from a spherical piston, set in the side of a rigid sphere, undergoing harmonic radial surface vibrations in an acoustic halfspace is analyzed in an exact fashion using the classical method of separation of variables.

Enhancing SDT Efficacy of Doxorubicin‐Loaded Sonosensitizer Micelles to Overcome Resistance of Cancer Therapy by Optimizing Acoustic Parameters

Aggregate
Tumor drug resistance has been reported to be associated with drug efflux in tumor cells. Recently, a noninvasive and safe mechanism, sonodynamic therapy (SDT), has been proposed to be an oxidative stress strategy to potentially overcome drug efflux, but

Review of Acoustic Sources Alternatives to a Dodecahedron Speaker

Applied Sciences, 2019
An omnidirectional source is required in many acoustic measurements. Commonly a dodecahedron speaker is used but due to various factors (e.g., high cost, transportation difficulties) other acoustic sources are sometimes preferred. In this review, fifteen
