A cracking sound, then silence. The Hyatt Regency collapse killed 114 people, all because of one design change approved over ...

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as ...

The achievement, confirmed by ASML technologists Michael Purvis and Teun van Gogh, does not involve a proof-of-concept demonstration or a short-lived experiment. The company says the ...

Researchers at Zhejiang University have found a way to stop performance-killing Auger recombination in perovskite lasers, using a clever additive during processing. Their method produced a ...

Abstract: Joint communication and radar/radio sensing (JCAS) is envisioned as a promising capability in various future vehicular platforms, such as smart cars. The generalized joined coupler (GJC) ...

This passive beamforming topology is not well known but is widely used — a common situation in the RF world. For many years, radar applications defined much of the world of directional antennas. These ...

The construction of concrete-filled steel tube tied-arch bridges typically employs the “beam first and arch later” methodology. In this approach, tie beams are initially constructed on temporary ...

Accurate primary beam calibration is essential for precise brightness measurements in radio astronomy. The VLA Low-band Ionosphere and Transient Experiment (VLITE) faces challenges in calibration due ...
