Abstract: In this letter, we devise two moving sampling schemes for two-dimensional (2D) direction-of-arrival (DOA) estimation using sparse planar arrays. The proposed schemes are applied to two ...

Neutral-atom arrays are a rapidly emerging platform to create quantum computers. In a foundational study led by graduate students Aaron Holman and Yuan Xu from the Will and Yu labs, respectively, the ...

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...

The start of the new year brings the retail industry closer to an important inflection point. By the beginning of 2027, every point of sale (POS) system must be able to scan 2D barcodes such as QR ...

Nvidia's graphics processing units are the industry standard in artificial intelligence infrastructure, but the company is truly formidable due to its full-stack strategy. Meta Platforms is using ...

XREAL is wrapping up 2025 with the launch of a new entry-level AR glasses model, the XREAL 1S. It sits below the more expensive XREAL One Pro (announced in July) in the lineup and is the first in the ...

A novel strategy employs 2D materials to construct cascaded band alignment, enabling efficient charge transport and reducing energy loss. An innovative approach utilizes donor–acceptor blends; active ...

All but 10 of the built E-2D Advanced Hawkeyes are now capable of receiving aerial refueling. Credit: Northrop Grumman The U.S. Navy’s Northrop Grumman E-2D Advanced Hawkeye has become the most ...

Copilot 3D will turn your 2D images into 3D models. The tool is freely available to anyone, though you do need a Microsoft account. Microsoft suggests using an image with a single subject, even ...

Two-dimensional (2D) semiconductors, materials that can conduct electricity and are only a few atoms thick, are promising alternatives to the conventional silicon-based semiconductors currently used ...

In Fe5GeTe2, researchers directly observe atomic-scale coherence linking charge density waves, Kondo physics, and ferromagnetism for the first time. (Nanowerk News) What if electricity and magnetism, ...
