Firstly, in Westernised countries stroke is far less common as a cause of death than is its sister ...
متن کاملSqueezing more out of ultrafast x-ray measurements
Fluctuations are unavoidable in any physical system but they can be the bane of precision measurements. A way around this is to generate what are called squeezed states. In a squeezed state, the uncertainty in one of a pair of conjugate variables (such as position and momentum) can be reduced below the quantum limit, so long as the product of the variables satisfies the Heisenberg relation. In ...
متن کاملForty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
