The acoustic properties of single crystals of the high temperature superconductor YBa sub 2 Cu sub 3 O sub 7 have been measured at temperatures between 0.1 and 300K for frequencies near 10 sup 3 an
While the surface Rayleigh phonon is normally the dominant long wavelength acoustic feature for a film on a substrate, the rich spectrum of higher order excitations also offers novel possibilities
This letter reports picosecond laser-based measurements of acoustic waveguiding in a thin film of nanoporous silica (similar to silica aerogel or xerogel) on silicon for wavelengths between 2.5 and
Previous research by the authors has been directed toward phonetic transcription of fluent speech. We have applied our techniques to speech recognition on the DARPA Resource Management Task.
E A S U R E M E N T S in acoustics may be said to date from the fifth century B.C., when Pythagoras observed that the lengths of strings giving the fifth, the fourth and the octave had the ratios 6
Changes in magnitude and variability of duration, fundamental frequency, formant frequencies, and spectral envelope of children's speech are investigated as a function of age and gender using data
Be able to distinguish and characterize abnormal auscultation sounds is important for an accurate medical diagnosis.

Neocortical pyramidal neurons have extensive axonal arborizations that make thousands of synapses.
The dynamics of magnetic fluctuations have been investigated in the random frustrated antiferromagnet Cd sub (1-x) Mn sub x Te.
