Abstract: Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays ...

NVIDIA integrates Universal Sparse Tensor into nvmath-python v0.9.0, boosting sparse deep learning and scientific computing with zero-cost PyTorch interoperability. Why it matters: Sparse data is a ...

Abstract: The sparse array could reduce the cost of physical antennas. However, implementing wideband beamforming directly based on the covariance matrix of the received signals from the sparse array ...

Transcranial focused ultrasound (tFUS) is a non-invasive neuromodulatory tool that holds promise for various neuropsychiatric disorders. While it offers several distinct advantages, it also faces ...

Accurate visualization of the focal spot in high-intensity focused ultrasound (HIFU) is essential for safe and effective therapeutic guidance. Passive acoustic mapping (PAM) provides a noninvasive ...

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 ...

Researchers at DeepSeek on Monday released a new experimental model called V3.2-exp, designed to have dramatically lower inference costs when used in long-context operations. DeepSeek announced the ...

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 ...

Ever wonder how some folks just seem to breeze through coding challenges and land those awesome tech jobs? A lot of it comes down to practice, and platforms like HackerRank are super helpful for that.

In the dynamic realm of data structures, sparse arrays represent one of the most elegant solutions to a fundamental computational challenge: efficiently managing arrays where the majority of elements ...

If you work with data, you’ve likely heard of the famous library, NumPy. And if not, well, you might have been living under a rock (!kidding(iykyk)). NumPy arrays are often celebrated for being more ...
