Topological photonics has emerged as a powerful paradigm for achieving robust light transport that is immune to imperfections, disorder, and structural defects. By harnessing principles from condensed ...

The Transportation Department is pushing hard for the new system to go online in 2028, with a price tag for modernization that could reach $31.5 billion. Peraton has won the massive contract to lead a ...

For frequency and voltage stability control of grid-forming converters in high-power electronic scenarios, this paper proposes a grid-forming converter grid-connection stability control strategy based ...

Creating a virtual brain may sound like a science-fiction nightmare, but for neuroscientists in Japan and at Seattle’s Allen Institute, it’s a big step toward a long-held dream. They say their ...

Neros is proud to announce its selection as one of the three primary manufacturers of FPV drones for the U.S. Army’s Purpose-Built Attritable Systems (PBAS) program Tranche 1 — an initiative designed ...

Almost everyone agrees that the US air traffic control system is broken. Longstanding staffing shortages. Antiquated technology. And now, air traffic controllers are caught in the middle of a ...

Years ago, I identified “personal control” as a key component of a resilient outlook and a resilient life. I defined personal control as the ability to focus our time and energy on factors over which ...
