Noise exposure immediately activates cochlear mitogen-activated protein kinase signaling
Noise and Health, 2014 Noise-induced hearing loss (NIHL) is a major public health issue worldwide. Uncovering the early molecular events associated with NIHL would reveal mechanisms leading to the hearing loss.

Evaluation of the annoyance due to helicopter rotor noise [PDF]
A program was conducted in which 25 test subjects adjusted the levels of various helicopter rotor spectra until the combination of the harmonic noise and a broadband background noise was judged equally annoying as a higher level of the same broadband ...

High‐Gain Ag2Te/MoS2 Hybrid Photodetectors for Short‐Wave Infrared Imaging
Advanced Materials, EarlyView.A precision‐engineered short‐wave infrared image sensor based on a 0D/2D Ag2Te/MoS2 hybrid structure is demonstrated in this work. The device exploits photodoping at the nanoscale interface to achieve broadband detection from visible to infrared wavelengths with high responsivity and fast response.

Effects of simulated flight on the structure and noise of underexpanded jets [PDF]
Mean plume static and pitot pressures and far-field acoustic pressure were measured for an underexpanded convergent nozzle in simulated flight. Results show that supersonic jet mixing noise behaves in flight in the same way that subsonic jet mixing noise
