Thermodynamic Method for Measuring the B/A Nonlinear Parameter Under High Pressure
Engineering Transactions, 2014 The nonlinearity parameter B/A is a measure of the nonlinearity of the equation of state for a fluid. The nonlinearity parameter B/A is a physical parameter often used in acoustics, from underwater acoustics to biology and medicine.

The acoustic force density acting on inhomogeneous fluids in acoustic fields [PDF]
, 2016 We present a theory for the acoustic force density acting on inhomogeneous fluids in acoustic fields on time scales that are slow compared to the acoustic oscillation period.

Advanced Functional Materials, EarlyView.Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Pressure Waves During Granular Flows in Varying Gravity Environments [PDF]
EPJ Web of ConferencesWe present results of LAMMPS Molecular Dynamics simulations of 2D gravity-driven flows of 30,000 soft uniform spheres through a vertical silo. We vary the gravitational field (G), elastic modulus of the particles (E), and silo outlet diameter (D).

Acoustic Supercoupling in a Zero-Compressibility Waveguide
, 2018 Funneling acoustic waves through largely mismatched channels is of fundamental importance to tailor and transmit sound for a variety of applications. In electromagnetics, zero-permittivity metamaterials have been used to enhance the coupling of energy in
