Scientists at Tokyo Institute of Technology and Socionext Inc. have developed a novel transceiver for enabling seamless communication between earth ground platforms and satellites in the low, middle, and geostationary earth orbits. Among other things, this transceiver could bring Internet to people in remote rural areas and at sea.
According to their new study published in Computers & Security, the ability to launch massive distributed denial-of-service (DDoS) attacks via a botnet of compromised devices is an exponentially growing risk in the Internet of Things (IoT). Such massive attacks, possibly emerging from IoT devices in home networks, impact the attack target, as well as the infrastructure of telecommunication service providers (telcos).
This study uses 2018 data from the National Health and Aging Trends Study to assess how common it is for older adults in the United States to be unprepared to access video or telephone telemedicine because of disability or inexperience with technology.
Louisiana State University Associate Professor of Physics Mark M. Wilde and his collaborator have solved a 20-year-old problem in quantum information theory on how to calculate entanglement cost--a way to measure entanglement--in a manner that's efficiently computable, useful, and broadly applicable in several quantum research areas.
New research from Professor Feng Li, Chair of Information Management at City's Business School has outlined three new approaches that digital innovators can take to reduce the risk of failure and seize competitive advantage in the industry.
Researchers from Drexel University and the Korea Institute of Science and Technology have discovered a MXene material that presents exceptional electromagnetic interference shielding abilities.
Miniaturized computer systems and wireless technology are offering scientists new ways to keep tabs on reactions without the need for larger, cumbersome equipment. In a proof-of-concept study in ACS Sensors, researchers describe an inexpensive new device that functions like a conventional magnetic stir bar, but that can automatically measure and transmit information on a solution's color, viscosity and a variety of other attributes to a smart phone or computer.
Machine learning performed by neural networks is a popular approach to developing artificial intelligence, as researchers aim to replicate brain functionalities for a variety of applications. A paper in the journal Applied Physics Reviews proposes a new approach to perform computations required by a neural network, using light instead of electricity. In this approach, a photonic tensor core performs multiplications of matrices in parallel, improving speed and efficiency of current deep learning paradigms.
'Mysterious' vibrational properties of nanoscale glasses studied by subjecting novel (and slightly explosive) particles of aluminium wrapped in a thin alumina skin to neutron spectroscopy measurement at ANSTO. Experimental/theory collaboration shows lattice vibrations in ultra-thin alumina glass result in a characteristic peak in the density of states at 2.5 meV. The boson peak frequency measured by neutron spectroscopy is in agreement with the values calculated from molecular dynamics simulations.
The Internet has deeply changed our ways of living but at the same time introduced serious security and privacy issues. The quantum internet promises to fundamentally solve these issues. Currently however, the major obstacles towards its development are the scarcity of quantum resources. Researchers in Japan have taken a major step forward by significantly reducing the number of resources required for such tasks. They published their findings on May 27 in Physical Review Letters.
