Researchers have discovered a new way to produce high energy photon beams. The new method makes it possible to produce these gamma rays in a highly efficient way, compared with today's technique. The obtained energy is a billion times higher than the energy of photons in visible light. These high intensity gamma rays significantly exceed all known limits, and pave the way towards new fundamental studies.
A smart watch that takes the user to another dimension and a smart ring that provides powerful feedback are among the top technology Dartmouth College will bring to the 30th ACM User Interface Software and Technology Symposium (UIST 2017).
This study examines how small-world networks occur within bigger and more complex structures.
It's really surprising: it turns out that among simple electronic circuits, built of just a few components, many of them behave chaotically, in an extremely complicated, practically unpredictable manner. Physicists from the Institute of Nuclear Physics Polish Academy of Sciences in Cracow have discovered, examined and described dozens of new, unusual circuits of this type. What is especially interesting is that one of the circuits generates voltage pulses very similar to those produced by neurons, only it does so a thousand times faster.
'The autonomous HydroCamel II integrates state-of-the-art technologies, including high-level maneuvering in six degrees of freedom and an ability to dive almost vertically,' says Professor Hugo Guterman of the BGU Department of Electrical and Computer Engineering and head of LAR. 'Until now, these capabilities were limited to remotely operated underwater vehicles (ROVs), which must be tethered by an umbilical cable to a host ship for its power and air source. The HydroCamel II is completely autonomous.'
Slow internet speeds and the Internet 'rush hour' -- the peak time when data speeds drop by up to 30 percent -- could be history with new hardware designed and demonstrated by UCL researchers that provides consistently high-speed broadband connectivity.
Harvard computer scientist found that the Johnson-Lindenstrauss lemma, a 30-year-old therum, is the best approach to pre-process large data into a manageably low dimension for algorithmic processing.
New University of Washington research finds that for a budget of roughly $1,000, it is possible for someone to track your location and app use by purchasing and targeting mobile ads. The team hopes to raise industry awareness about the potential privacy threat.
Astrophysicist Chris Fryer was enjoying an evening with friends on Aug. 25, 2017, when he got the news of a gravitational-wave detection by LIGO, the Laser Interferometer Gravitational-wave Observatory.
Researchers from the Texas Advanced Computing Center, working with classicists and computer scientists from The University of Texas at Austin, developed a method to preserve digital humanities databases. The preservation strategy allows scholars to re-launch a database application in a variety of environments -- from individual computers, to virtual machines, to future web servers -- without compromising its interactive features. They presented the work at the 2017 ACM/IEEE Joint Conference on Digital Libraries (JCDL).
