Abstract: In order to solve the real-time positioning problem of flexible wearable ultrasonic transducer array unit under dynamic conditions, a new transducer array based on button flexible structure ...

Since 2008, Stack Overflow has been an immensely helpful resource for developers, allowing them to crowdsource answers to their coding questions — and resulting in a vast online repository of coding ...

"With our metasurface tweezer array approach, we hope to scale neutral-atom arrays even further, perhaps even beyond 100,000 atoms." This scaling comes from a fundamentally new approach to generating ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Abstract: This paper presents a two-dimensional (2D) wide-angle scanning phased array based on a pattern reconfigurable two-element subarray. The two-element subarray design method enables flexible 1D ...

Researchers are exploring MXenes, 2D materials that could transform air into ammonia for cleaner fertilizers and fuels. Their atomic structures can be tuned to optimize performance, making them ...

Despite the possibility of a government shutdown next week, the Education Department is slated to begin the complicated endeavor of determining how to carry out the sweeping higher ed changes in ...

Section 1. Purpose. Artificial intelligence (AI) is a foundational technology that will define the future of economic growth, national security, and global competitiveness for decades to come. The ...

Some scientists think quantum mechanics may be working in a lower-dimensional setting, giving us the illusion of our 3-dimensional universe. This idea changes the nature of our perceived reality, ...

When most people think of shapes, they imagine a triangle, a rectangle, or maybe even a fancier-sounding rhombus or trapezoid. But to mathematicians, shapes encompass a vast universe of surprising ...

In April 1982, Prof. Dan Shechtman of the Technion–Israel Institute of Technology made the discovery that would later earn him the 2011 Nobel Prize in Chemistry: the quasiperiodic crystal. According ...
