A Parametric Study of the Acoustic Mechanism for Core-Collapse Supernovae [PDF]
, 2017 We investigate the criterion for the acoustic mechanism to work successfully in core-collapse supernovae. The acoustic mechanism is an alternative to the neutrino-heating mechanism.

The impact of vaporized nanoemulsions on ultrasound-mediated ablation [PDF]
, 2013 BACKGROUND: The clinical feasibility of using high-intensity focused ultrasound (HIFU) for ablation of solid tumors is limited by the high acoustic pressures and long treatment times required.

No Evidence Supporting Flare Driven High-Frequency Global Oscillations
, 2012 The underlying physics that generates the excitations in the global low-frequency, < 5.3 mHz, solar acoustic power spectrum is a well known process that is attributed to solar convection; However, a definitive explanation as to what causes excitations in
