Abstract: Large‐aperture antenna arrays promise fine angular resolution, but their dense layouts usually lead to prohibitive cost and design complexity. Sparse arrays present a compelling alternative, ...

Abstract: Sparse linear arrays serve as the fundamental basis for sparse signal processing and have demonstrated remarkable direction-of-arrival (DOA) estimation performance. Due to the merit of ...

So, you’ve got a HackerRank test coming up, huh? It’s pretty common these days, with lots of companies using it to see if you can code. It can feel a bit daunting, but honestly, it’s just another ...

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 ...

We’ll explore how Array’s integration of APA’s fixed-tilt and A-frame designs opens new possibilities in difficult terrains and why foundation choice is critical to structural resilience and long-term ...

Quantifying stratigraphic uncertainty is crucial for reliable risk assessment and informed decision-making in geotechnical and geological engineering. However, accurately modeling complex stratigraphy ...

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 ...

MACOM Technology Solutions Inc. has introduced a new wideband front end module (FEM) that operates across a frequency range of 2 to 18 GHz, suitable for electronic countermeasures and phased array ...

To satisfy the seafood needs of billions of people, offering them access to a more biodiverse array of fish creates opportunities to mix-and-match species to obtain better nutrition from smaller ...
