It includes new information on cryogenic electronics and quantum information processing, added benchmarks for applications, and supplemental information and metrics from the More Moore team. There is a newly released summary from Beyond CMOS, and updates for emerging devices, outside systems connectivity technology, […]
What do dragonflies teach us about missile defense?
Science Daily July 24, 2019 Researchers at Sandia National Laboratory are examining whether dragonfly-inspired computing could improve missile defense systems, which have the similar task of intercepting an object in flight, by making on-board computers smaller without sacrificing speed or accuracy. In recent computer simulations, faux dragonflies in a simplified virtual environment successfully caught their prey using computer algorithms designed to mimic the way a dragonfly processes visual information while hunting. Missile defense systems rely on established intercept techniques that are computation heavy. The dragonfly model could potentially, shrink the size, weight and power needs of onboard computers. It may […]

1 in 5 Cities Is About to Have a Climate Unknown to Any Place on Earth
Science Alert July 11, 2019 Researchers in Switzerland analyzed city pairs for 520 major cities of the world and tested if their climate in 2050. They found that even under an optimistic climate scenario 77% of future cities are very likely to experience a climate that is closer to that of another existing city than to its own current climate. As a general trend, they found that all the cities tend to shift towards the sub-tropics, with cities from the Northern hemisphere shifting to warmer conditions, on average ~1000 km south and cities from the tropics shifting to drier conditions…read […]
Ammonia from agriculture influences cloud formation over Asia
Science Daily July 11, 2019 An international team of researchers (Germany, France, Italy) has shown that the presence of ammonium nitrate particles in the upper troposphere from the Eastern Mediterranean to the Western Pacific is fed by convection that transports large amounts of ammonia from surface sources into the upper troposphere. Solid ammonium nitrate particles in the upper troposphere play a hitherto neglected role in ice cloud formation and aerosol indirect radiative forcing…read more. Open Access TECHNICAL ARTICLE
Artificial intelligence (AI) designs metamaterials used in the invisibility cloak
EurelAlert July 14, 2019 Researchers in South Korea developed an AI system and taught it to design arbitrary photonic structures and gave additional level of freedom of the design by categorizing types of materials and adding them as a design factor, which made it possible to design appropriate materials for relevant optical properties. Previous studies required inputs of materials and structural parameters beforehand and adjusting photonic structures afterwards. The current process significantly reduced the time needed to design photonic structures…read more. Open Access TECHNICAL ARTICLE
Chaos theory produces map for predicting paths of particles emitted into the atmosphere
Eurekalert July 16, 2019 Floating air particles following disasters and other largescale geological events can have a lasting impact on life on Earth. Using available wind data, researchers in Hungary have developed a model for following air particles as they travel around the globe. They found that lifetimes of particles ranged from about two to 150 days for typical volcanic ash particles, more than 10% of smaller particles survive in the atmosphere as much as one year, and more than 1% survive two years, particles coming from the area around the equator remain in the atmosphere for the longest time, […]
Coupled exploration of light and matter
Science Daily July 15, 2019 Polaritonics is based on the strong coupling of photons to atomic or electronic excitations in an optical resonator. An international team of researchers (Switzerland, France) describes experiments which indicate that, in addition to strong correlations in the electronic ground state, exciton–electron interactions leading to the formation of polaron-polaritons have a key role in enhancing the nonlinear optical response of the system. The research opened fresh perspectives for exploring both ingredients of the polariton, novel functionalities for photonic devices and fundamental insight into exotic states of matter…read more.

Electrical engineers develop ‘beyond 5G’ wireless transceiver
Science Daily July 12, 2019 An international team of researchers (USA – UC Irvine, France) fabricated a single-channel 115-135-GHz receiver prototype in a 55-nm SiGe BiCMOS which has max conversion gain of 32 dB and a min noise figure of 10.3 dB. They measured a data rate of 36 Gb/s at 30-cm distance with the received 8PSK signal being directly demodulated on-chip at a bit-error rate of 1e-6. The prototype occupies 2.5 x 3.5 mm² of die area, including PADs and test circuit and consumes a total dc power of 200.25 mW…read more. TECHNICAL ARTICLE
Intel’s new AI chips can crunch data 1,000 times faster than normal ones
MIT Technology Review July 16, 2019 Intel has just unveiled Pohoiki Beach, a system that contains 64 of its Loihi AI processors with neuromorphic chips. They can perform certain data-crunching tasks up to 1,000 times faster than more general-purpose processors such as CPUs and GPUs, while using much less power. The company will produce a system capable of simulating 100 million neurons by the end of 2019. Researchers will then be able to apply it to a whole new set of applications…read more.
