China’s j-20 stealth fighter is operational. It has small wings and is not optimized to beat other advanced fighters like the US F-22 raptor. Short-range tactical fighters like the F-22, F-35 and J-20 are ill-suited for operations in the Western Pacific where distances are vast and bases are scarce. The same geographic constraints also apply …
Quantum Monte Carlo methods use random sampling to analyze many-body quantum problems where the equations involved cannot be solved directly. Ringel and Kovrizhi showed that attempts to use quantum Monte Carlo to model systems exhibiting anomalies, such as the quantum Hall effect, will always become unworkable. They discovered that the complexity of the simulation increased …
The Stratolaunch team (funded by billionaire Paul Allen) is proud to announce that our aircraft is one step closer to providing convenient, reliable, and routine access to low Earth orbit. The first test flights are planned to begin in 2017, with a goal of a commercial launch by 2020. The first flight of the carrier …
IBM Watson for Oncology uses the latest deep learning techniques to provide clinicians worldwide with evidence-based treatment plans. For many of Zhao’s patients – and countless others like them – Watson provides quite literally a lifeline. At least 40 hospitals in China have deployed IBM’s Watson since it became available last year. Meanwhile, the use …
A new radar sensor that can capture real-time video through clouds has been developed and demonstrated by the U.S. military. The U.S. Defense Advanced Research Projects Agency, or DARPA, said the sensor is part of its Video Synthetic Aperture Radar, or ViSAR, program that recently completed flight testing. “The recent flight tests of the ViSAR …
