In a mesmerising blend of art and mathematics, a research student from University College London (UCL) has recently gained widespread attention for creating intricate images solely through ...

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.

Each cavity is driven by a high-power klystron, which is a tube containing electron beams. The electron beams are intensity-modulated to a frequency of 400 MHz, or 400 million oscillations per second.

It is recognized as a relatively low frequency (10–30 kHz) longitudinal oscillation of the discharge current and the plasma parameters. Although breathing instability is widely studied in the ...
