Ultrasonically Assisted Hammer-Action Penetrators in Planetary Regolith [PDF]
, 2018 This paper describes the effects of combining ultrasonic vibration with hammer-action style penetrators, such as the HP3 probe on the InSight mission. By synchronizing short pulses of vibration with the impact of the hammer, the number of hammer strikes ...

The phase shift of an ultrasonic pulse at an oil layer and determination of film thickness [PDF]
, 2005 An ultrasonic pulse incident on a lubricating oil film in a machine element will be partially reflected and partially transmitted. The proportion of the wave amplitude reflected, termed the reflection coefficient, depends on the film thickness and the ...

Molecular Oncology, EarlyView.This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.
