New research has revealed exactly how sounds like squeaking trainers, bike brakes in need of a tune-up or chalk on a blackboard occur and how they ...

Tiny, repeating detachments between sole and floor — thousands of times a second — create the distinctive squeak heard on the court, data show.

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or ...

Abstract: The power supply of the T/R modules in active phased array radar is a kind of pulsed power supply (PPS). In case of low pulse repetition frequency (PRF), an active pulsed power compensator ...

Search for papers published between November 2014 and November 2024 in the PubMed database that use PRF to treat chronic pain. We used “Pulsed radiofrequency, PRF, Pulsed RF for Pain, chronic pain, ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special technique to film laser light in real time, researchers observed how ...

Silanna Semiconductor has launched the FirePower series of laser driver ICs that significantly reduce the size and increase the peak power of LiDAR applications. FirePower Laser Driver ICs are the ...

One of the projects we’ve been crowing about coming up on Netflix in 2025 is the streamer’s first-ever medical procedural series, Pulse. The series has had the lid lifted on it with an April 2025 ...

A research team has achieved a major advance in X-ray science by generating unprecedented high-power attosecond hard X-ray pulses at megahertz repetition rates. This advancement opens new frontiers in ...
