Abstract: A synthetic aperture radar (SAR) image transform method is proposed based on random period amplitude and frequency shifting joint modulation. The random period amplitude sequence is designed ...

Anybody can develop high frequency hearing loss, but it becomes more common with age. Exposure to loud sounds or high frequency sounds are common causes of ear damage in younger people.

The paper is published in the journal Nature. In a world-first, scientists used precisely controlled optical traps, known as "magic-wavelength optical tweezers," to create a highly stable ...
