Researchers constructed a transmission system that makes full use of wavelength division multiplexing technology by combining different amplifier technologies, to achieve a transmission demonstration with date-rate of 319 terabits per second, over a distance of 3,001 km. Using a common comparison metric of optical fiber transmission the data-rate and distance produce of 957 petabits per …
JGC Holdings (Japanese company) has invested $40 million for a roughly 3% stake in NuScale, developing small modular pressure water nuclear reactor. The Japanese group will work with NuScale’s parent, U.S.-based engineering company Fluor, on construction management and other aspects of the Idaho project. The partners will eventually make similar projects in the Middle East …
Researchers from Yokohama National University in Japan have developed a prototype microprocessor using superconductor devices that are about 80 times more energy-efficient than CMOS semiconductor devices. Computers currently use 10% of global electricity. The adiabatic quantum-flux-parametron (AQFP) is a building block for ultra-low-power, high-performance microprocessors, and other computing hardware for the next generation of data …
Many important and valuable planning and scheduling problems in logistics and automation are combinatorial optimization problems. The most famous problem of this type is the traveling salesman problem. The salesman problem is this question: “Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits …
JapanesecChemical product maker Kurabo Industries will import and sell in Japan COVID-19 test kits developed by a Chinese firm that can detect new coronavirus in 15 minutes. This is much faster than other tests which take many or even days when they are sent to labs with large equipment. Kurabo plans to sell the kits …
Iran, South Korea and Italy have significant levels of COVID-19 coronavirus. The world total of official COVID-19 coronavirus cases is over 80,000 with 2705 deaths. This is not including mild cases with very few or no symptoms and without needing hospitalization. There are undetected cases as well. The number of coronavirus cases in South Korea …
China revised up its nominal 2018 gross domestic product (GDP) by 2.1% to 91.93 trillion yuan ($13.08 trillion) and this keeps them tracking to the promise doubling the size of its economy by 2020 from 2010. The current round of revisions is the result of the census uncovering previously unrecorded activity. China is tracking to …
Before the tsunami in 2011, Japan was generating 30% of its electricity from over 50 nuclear reactors, but all were shutdown within 14 months of the accident. A total of nine units have restarted since 2015, while 17 reactors are in the process of gaining approval to restart. Tohoku Electric Power Company has received initial …
The Carnival of Space 631 is up at Urban Astronomer. Universe Today – Hayabusa 2 has one Last Lander it’s Going to Throw at Ryugu. JAXA (Japan Space Agency) posted time-lapse photos of target markers falling towards the surface of the Ryugu asteroid. There was a slight parabolic arc to their descent. , also issued …
Japanese billionaire Yusaku Maezawa plans to sell a 30% stake in his online fashion-retail company, Zozo, and he will get $2.3 billion. Yusaku Maezawa #Space_News: Billionaire @yousuck2020 is resigning from his fashion company to make time to train for his #DearMoon mission, a 2023 voyage around the Moon with @SpaceX's #Starship, & also to fly …
Fujitsu calls its quantum device a quantum-inspired Digital Annealer. It is classical hardware emulating systems. They are trying to solve a complex combinatorial optimization problem currently unsolvable by conventional computers in practical timeframe. Fujitsu’s research scientists are leveraging quantum algorithms on digital circuit-based architecture. Inspired by the quantum phenomena within silicon architectures, they have used …
