Abstract: This paper proposes a multi-beam synthesis method for uniform sparse arrays based on visible region analysis. By analyzing the distribution characteristics of the array pattern within the ...

Abstract: Recently, structured sparse arrays have been developed for improving direction-of-arrival (DOA) estimation performance on moving platforms. By employing synthetic aperture processing ...

In April 2026, a video on X (archived) apparently showed empty seats in an arena in which Vice President JD Vance was speaking. The event, part of a tour conservative nonprofit Turning Point USA ...

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 ...

Thinking about getting into coding or leveling up your skills? You’ve probably heard of HackerRank. It’s a big name in the tech world for practice and hiring. But the big question on a lot of people’s ...

Please provide a description of what you'd like to do. I am using sparse arrays with xarray and I found that a simple DataArray.sum() operation performs poorly with skipna=True, which is the default ...

Your browser does not support the audio element. TL;DR: Caching bit shifts looks smart but makes code up to 6× slower. Modern CPUs and compilers make direct ...

error: halt reached - Sparse arrays can't be zippered with anything other than their domains and sibling arrays This is almost correct as it talks about zippering, which seems to be an internal ...
