Digital twin models may enhance future autonomous systems

Systems controlled by next-generation computing algorithms could give rise to better and more efficient machine learning products, a new study suggests.

Using machine learning tools to create a digital twin, or a virtual copy, of an electronic circuit that exhibits chaotic behavior, researchers found that they were successful at predicting how it would behave and using that information to control it.

Many everyday devices, like thermostats and cruise control, utilize linear controllers — which use simple rules to direct a system to a desired value...

Extreme conditions on rocky planet surprise scientists. UC Riverside astrophysicist Stephen Kane had to double check his calculations. He wasn’t sure the planet he was studying could be as extreme as it seemed.

Kane never expected to learn that a planet in this faraway star system is covered with so many active volcanoes that seen from a distance it would take on a fiery, glowing-red hue.

“It was one of those discovery moments that you think, ‘wow, it’s amazing this can actually exist,” Kane said. A paper detailing the discovery has been published in The Astronomical Journal.

Launched in 2018, NASA’s Transiting Exoplanet Survey Satellite, or TESS, searches for exoplanets — planets outside our solar system — tha...

A simple oral rinse could provide early detection of gastric cancer, the fourth-leading cause of cancer deaths worldwide, according to a study scheduled for presentation at Digestive Disease Week (DDW) 2024.

“In the cancer world, if you find patients after they’ve developed cancer, it’s a little too late,” said Shruthi Reddy Perati, MD, author and general surgery resident at Rutgers Robert Wood Johnson School of Medicine. “The ideal time to try to prevent cancer is when it’s just about to turn into cancer. We were able to identify people who had precancerous conditions. As a screening and prevention tool, this has enormous potential.”

Researchers analyzed bacteria samples from the mouths of 98 patients scheduled for endoscopy, including 30 known...

The rapid advancement in photonic integrated circuits (PICs), which combine multiple optical devices and functionalities on a single chip, has revolutionized optical communications and computing systems.

For decades, silicon-based PICs have dominated the field due to their cost-effectiveness and through their integration with existing semiconductor manufacturing technologies, despite their limitations with regard to their electro-optical modulation bandwidth. Nevertheless, silicon-on-insulator optical transceiver chips were successfully commercialized, driving information traffic through millions of glass fibers in modern data centers.

Recently, the lithium niobate-on-insulator wafer platform has emerged as a superior material for photonic integrated electro-optical modulators d...
