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 ...

Abstract: In a sparse array, the holes in the corresponding difference co-array (DCA) limit the length of the consecutive subarray, which in turn reduces the number of achievable uniform degrees of ...

HackerRank is a pretty cool place to get better at coding. It’s got tons of challenges that really make you think and figure things out faster. Whether you’re just starting out or you’ve been coding ...

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

Near-field focused antenna arrays have emerged as a critical technology for optimising electromagnetic energy delivery and imaging. By finely controlling the phases and amplitudes of individual ...

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 ...

Pull requests help you collaborate on code with other people. As pull requests are created, they’ll appear here in a searchable and filterable list. To get started, you should create a pull request.

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 ...

Add a description, image, and links to the sparse-array topic page so that developers can more easily learn about it.
