Abstract: Doppler shift has significant implications in Low Earth Orbit (LEO) constellations due to the rapid relative movement of satellites. This letter presents a novel approach based on stochastic ...

This repository provides code and workflows to test several state-of-the-art vehicle detection deep learning algorithms —including YOLOX, SalsaNext, RandLA-Net, and VoxelRCNN— on a Flash Lidar dataset ...

Bats are impressive navigators. Like so many mini submarines equipped with sonar, they deftly navigate dark forests and caves by listening for the echoes of their own calls. But how bats can tell ...

A survey by The Motley Fool found investors are confident that artificial intelligence companies will deliver strong returns over the long haul. Nvidia and Alphabet are positioned to benefit from AI ...

The discovery of the rotational Doppler effect (RDE) has opened new opportunities for detecting parameters of rotating targets. In recent years, the physical mechanisms underlying this effect have ...

Donald Trump’s decision to allow Nvidia Corp. to sell advanced chips to China marks more than just a shift in US tech policy. It also raises questions about how far he’ll go to steady ties with Xi ...

A popular sandwich chain known for its fresh-baked bread and Mac and Cheese is gearing up for store and bakery closures as it continues a multi-year streamlining initiative. Panera Bread, long known ...

In Alaska’s Brooks Range, rivers once clear enough to drink from now run orange and hazy with toxic metals. As warming thaws formerly frozen ground, it sets off a chemical chain reaction that is ...

COVID-19 Response: From March 2020 to February 2022, the World Bank allocated more than $1.4 billion to enhance pandemic preparedness, directly benefiting millions of people across 22 countries in ...

Two identical atomic beam vacuum systems are employed to minimize the impact of physical systems on the experiment. An ion pump with a 20 L/s pumping speed maintains long-term vacuum stability at 6E-8 ...
