The term “LASER” stands for Light Amplification by Stimulated Emission of Radiation. Lasers are a form of artificial light with a uniform phase and wavelength.

A core property of a laser is a low divergence angle that spreads out very little as it projects out further from its source. Lasers are also small enough to fit within compact instrumentation, which makes them ideal for inter-orbit optical communication systems and other systems for communicating over long distances. The Laser-based SSPS (L-SSPS) uses these unique properties to send solar-powered laser energy from space to Earth, where it is converted into electricity.

The transmittance of laser beams depends upon their wavelength. The SSPS Research Team has been studying a laser wireless power transmission technology operating at a wavelength of about 1070 nm (near-infrared) and a continuous-wave (CW).

It is known that faster-than-light (FTL) transmission of energy could be achieved if the transmission were considered in the framework of non-relativistic classical mechanics. Here we show that FTL transmission of energy could also be achieved if the transmission were considered in the framework of non-relativistic quantum mechanics. In our transmission protocol a two-spin Heisenberg model is considered and the energy is transmitted by two successive local unitary operations on the initially entangled spins. Our protocol does not mean that FTL transmission can be achieved in reality when the theory of relativity is considered, but it shows that quantum entanglement can be used in a recyclable way in energy transmission.

Known for giving classic Porsche cars second lives as modern-day beauties, LA-based Singer Vehicle Design is sharpening its competitive edge. It has teamed up with some of the masterminds behind Porsche’s most successful rally cars in building up a modern 911 off-roader fit to compete in the likes of Dakar and the Baja 1000. And boy will this carbon-bodied 911 look good doing it.

The idea for what Singer calls the All-Terrain Competition Study (ACS) came from a client who inquired about the possibility of transforming his air-cooled 964-gen Porsche 911 into an off-roader built to race and explore. The request diverged quite dramatically from what Singer was used to discussing with clients, so the company reached for some reinforcements by way of rally Porsche expert Richard Tuthill of Oxfordshire, UK-based Tuthill Porsche, teaming up on a car inspired by Dakar-winning Rothmans 911 SC/RS and 959 rally cars of the mid-80s.

Tuthill’s experience with competitive all-terrain Porsches spans generations. Richard is the son of Francis Tuthill, the rally driver who had a hand in preparing (and repairing) the Rothmans 911 SC/RS rally cars. That experience grew into a company, and the apple landed quite close to the tree. Richard and crew specialize in preparing race-ready Porsche cars for both off-road and race track, and their cars have taken home recent victories in events like the East African Safari Classic and FIA WRC R-GT championship.

Hey it’s Han from WrySci HX coming to you with exciting news out of Johns Hopkins University. A man was able to control two robotic arms simultaneously via a brain computer interface to the point of feeding himself. Amazing stuff! More below ↓↓↓

Optical micro-combs.

The invention could revolutionize neural networks and neuromorphic processing in general. “This breakthrough was achieved with ‘optical micro-combs’, as was our world-record internet data speed reported in May 2020,” said in a statement Swinburne’s Professor David Moss.

A new deep-learning algorithm could provide advanced notice when systems — from satellites to data centers — are falling out of whack.

When you’re responsible for a multimillion-dollar satellite hurtling through space at thousands of miles per hour, you want to be sure it’s running smoothly. And time series can help.

A time series is simply a record of a measurement taken repeatedly over time. It can keep track of a system’s long-term trends and short-term blips. Examples include the infamous Covid-19 curve of new daily cases and the Keeling curve that has tracked atmospheric carbon dioxide concentrations since 1958. In the age of big data, “time series are collected all over the place, from satellites to turbines,” says Kalyan Veeramachaneni. “All that machinery has sensors that collect these time series about how they’re functioning.”
