T-HSER: Transformer Network Enabling Heart Sound Envelope Signal Reconstruction Based on Low Sampling Rate Millimeter Wave Radar

Abstract: The four stages (first heart sound (S1), systole, second heart sound (S2), and diastole) of heartbeat sounds recorded by contact seismocardiogram (SCG) reflect the health of the heart, but ...

Phonon lasers unlock ultrabroadband acoustic frequency combs

Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

Harmonic Model Predictive Control for Tracking Sinusoidal References and Its Application to Trajectory Tracking

Abstract: Harmonic model predictive control (HMPC) is a recent model predictive control (MPC) formulation for tracking piece-wise constant references that includes a parameterized artificial harmonic ...

This Breakthrough Device Could Unlock Endless Energy, Scientists Say

The new pump has no moving parts. “Instead, it relies on thermoacoustics, the interaction between sound waves and heat, to move thermal energy,” Interesting Engineering writes. The pump uses that ...
