Over the last few issues, we've been talking about the math entity called a matrix. I've given examples of how matrices are useful and how matrix algebra can simplify complicated problems. A messy ...

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 ...

Optical computing uses photons instead of electrons to perform computations, which can significantly increase the speed and energy efficiency of computations by overcoming the inherent limitations of ...

3 MHz Matrix Array Transducer – the M3dV 3 MHz Matrix Array features a new monolithic design that enhances image reconstruction and improves image quality; it utilizes 1024 elements in a 32 x 32 grid ...

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...

This paper addresses the problem of rectangular matrix multiplication on bidirectional linear systolic arrays (SAs). We analyze all bidirectional linear SAs in terms of efficiency. We conclude that ...

Using an innovative, no-loss technique for combining smaller optical-MEMS arrays, researchers built and fully evaluated an electronically controlled, 240-input × 240-output, all-optical switching ...
