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 ...
Leaked API keys are no longer unusual, nor are the breaches that follow. So why are sensitive tokens still being so easily exposed? To find out, Intruder’s research team looked at what traditional ...
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 ...
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 ...
The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
To all the challenges the solar industry is facing today, add one more: cultivating a domestic market for lamb meat. It may seem an unlikely mission for clean-energy developers, but in many states, ...
Independent developer Omnaya Studios have announced Back In Time, a time travel-based side-scrolling action adventure game inspired by real-life catastrophic events. It will be available for ...
Abstract: Classical source number estimators are usually derived under the assumption of uniform white noise, which may degrade substantially with unknown nonuniform sensor noise. Advanced estimators ...
