The research study will help engineers to develop more different measures of the nature diagnosability based on application environment, network topology, network reliability, and statistics related to fault patterns.

A group of researchers from the Hong Kong University of Science and Technology and University of California, Santa Barbara, successfully demonstrated record-small electrically pumped micro-lasers epitaxially grown on industry standard (001) silicon substrates in a recent study. A submilliamp threshold of 0.6 mA, emitting at the near-infrared (1.3?m) was achieved for a micro-laser with a radius of 5 μm. The thresholds and footprints are orders of magnitude smaller than those previously reported lasers epitaxially grown on Si.

In a new paper, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL present an Alexa-like system that allows robots to understand a wide range of commands that require contextual knowledge about objects and their environments. They've dubbed the system 'ComText,' for 'commands in context.'

Scientists at Tokyo Institute of Technology, Nagoya University, Japan Synchrotron Radiation Research Institute (JASRI), National Institute for Materials Science (NIMS) and University of New South Wales have observed high-speed switching in Pb(Zr0.4Ti0.6)O3 thin films under applied rectangular electric field pulses.

The properties of materials can behave in funny ways. Tweak one aspect to make a device smaller or less leaky, for example, and something else might change in an undesirable way, so that engineers play a game of balancing one characteristic against another. Now a team of Penn State electrical engineers have a way to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a near zero thickness and weight.

For the first time, researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city.
