2021 article

mSOUND: An Open Source Toolbox for Modeling Acoustic Wave Propagation in Heterogeneous Media (vol 68, pg 1476, 2021)

Gu, J., & Jing, Y. (2021, October). IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, Vol. 68, pp. 3257–3257.

By: J. Gu n & Y. Jing n

author keywords: Mathematical model; Absorption; Media; Heating systems; Frequency control; Acoustic waves; Postal services
TL;DR: The authors regret that there were some mistakes pertaining to (1) - (3) and (5) of [1], where the frequency-independent absorption term γ∂p/∂t accounts for the absorption layer close to the computational boundary. (via Semantic Scholar)

2020 journal article

A modified mixed domain method for modeling acoustic wave propagation in strongly heterogeneous media

JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA, 147(6), 4055–4068.

By: J. Gu n & Y. Jing n

TL;DR: It is found that the MMDM is significantly more accurate than the MDM for strongly heterogeneous media, especially when the phase aberrating layer is approximately perpendicular to the acoustic beam. (via Semantic Scholar)

Dynamic assessment of dual-frequency microbubble-mediated sonothrombolysis in vitro

JOURNAL OF APPLIED PHYSICS, 125(8).

By: D. Suo n, B. Govind n, J. Gu n, P. Dayton n & Y. Jing n

TL;DR: It is found that dual- frequencies excitation in general produces a faster rate of clot dissipation in comparison to single-frequency excitation, and this observation is corroborated by cavitation signal detection. (via Semantic Scholar)
