Magnetic resonance elastography (MRE) is a noninvasive method of measuring tissue compliance. Current MRE methods rely on custom-built hardware to elicit vibrations that are tracked by MR imaging. Knowledge of the wave propagation can be used to calculate the local shear stiffness of the tissue. We sought to determine whether the vibrations of the patient table that result from low-frequency sw...

A _nite element formulation of the piezoelectric vibrations of quartz resonators based on Mindlin plate theory is derived[ The higher!order plate theory is employed for the development of a collection of suc! cessively higher!order plate elements which can be e}ective for a broad frequency range including the fundamental and overtone modes of thickness!shear vibrations[ The presence of electrod...

In Drosophila melanogaster, antennal hearing organs mediate the detection of conspecific songs. Combining laser Doppler vibrometry, acoustic near-field measurements and anatomical analysis, we have investigated the first steps in Drosophila audition, i.e. the conversion of acoustic energy into mechanical vibrations and the subsequent transmission of vibrations to the auditory receptors in the b...
