How does a DVL work? A DVL works by using the Doppler effect, which is the change in frequency of a wave due to the relative motion between the source of the wave and the observer. DVLs transmit a series of soun
When John's clock reads "1 hour" he sends the first signal. Because he is moving away from Hunter at 60% of the speed of light, the relativistic Doppler Effect causes Hunter to observe John's transmission to be ½ the source value. From our discussion above, ½ the frequency means ...
Descemet's membrane detachment (DMD) after ocular surgery is a very important yet under-reported complication [1 ]. In clinical practice, we come across many cases with partial or complete, and peripheral or central Descemet's membrane deatchment. Whereas a focal or peripheral DMD usually ...

Valve doesn't technically sell its skins for cash. Instead, every dollar deposited to a player's account gets converted to Steam credits, which can then be traded on the site for skins, other games or ancillary products. Once dollars become credits, the company does not convert them bac...
How does it compare to medical imaging devices? And is it enough to increase cancer rates in the general population? Then there are the questions about privacy. Can TSA agents see bits and pieces they shouldn't be seeing? And do they ever store or archive scans instead of deleting them ...
