The use of one-way resource reservation protocols, such as JET, in OBS network means that the bursts
are sent without any prior reservation path.
Sarah Burke Spolaor, from NASA's Jet Propulsion Lab, created the software used to detect these radio bursts
out from the all the interference, such as cell phone signals.
This is the first clear evidence that long-duration gamma-ray bursts
can be either associated with supernovas which do not have [the usual] properties or they can be produced by a different phenomenon," note Massimo Della Valle of the INAF-Astrophysical Observatory of Arcetri in Firenze, Italy, and his colleagues.
are seen to occur only in galaxies with lots of very young stars, since massive stars have very short lives and can't wander far from their birthplaces.
Twelve hours after the December burst
The industry is seeking an optimal architecture for metropolitan Ethernet optical transport networks, and optical burst
switching represents a promising new technology in this area.
Writing in the journal Science, the research team say the energy of the bursts
suggest they came from an extreme astrophysical event involving black holes or neutron stars, which form after a massive star expands and collapses in a supernova event.
Stanek and his collaborators examined the home galaxies of four gamma-ray bursts
, including one of the same galaxies studied by Fruchter's team, and recently posted their results online (http://xxx.
Stan Woosley and Andrew MacFadyen (University of California, Santa Cruz) described their scenario, in which the bursts
are caused by the supernova-like implosion of a very massive, rapidly rotating stellar core, which forms a black hole.
The VSC7970 TIA and VSC7967 Integrated Burst
Mode Laser Driver and Post Amplifier together provide a complete PMD IC solution for the ONU.
But even though an experiment onboard Compton has been recording bursts
with unprecedented sensitivity since April 1991, the mystery has only deepened.
An improved image processing sequence and a better memory management method in the EOS-1D Mark II N digital SLR has ramped up its burst
capability with the camera now able to shoot up to 22 RAW frames and up to 48 full-resolution JPEGs in burst
