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 ...

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 ...

Data-driven constitutive models, owing to their inherent flexibility, can outperform traditional plasticity-based models in certain aspects. When calibrating these models, ensuring adherence to ...

Abstract: Designing sparse arrays with fewer antenna elements and lower peak sidelobe level (PSLL) is critical and challenging for antenna arrays in terminal devices in Internet of Things (IoT) ...

This paper investigates sidelobe level (SLL) optimization in multi-wavelength inter-element spaced sparse aperiodic arrays, a critical component of 6 G sparse transmitarray systems. A convex ...

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 ...

JavaScript is a sprawling and ever-changing behemoth, and may be the single-most connective piece of web technology. From AI to functional programming, from the client to the server, here are nine ...

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 ...

The AI industry stands at an inflection point. While the previous era pursued larger models—GPT-3's 175 billion parameters to PaLM's 540 billion—focus has shifted toward efficiency and economic ...
