It is a sound evocative of high school: the characteristic squeak of sneakers on a basketball court. UK readers may, however, ...

Pulsed field ablation is a minimally invasive procedure to treat atrial fibrillation (AFib) and other arrhythmias. Instead of thermal energy used with traditional ablation techniques (radiofrequency ...

The squeaking of sneakers on a gym floor is usually attributed to friction, specifically a stick-slip variety that involves ...

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

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of ...

Abstract: An approach for generating frequency-hopping continuous-wave (CW) and pulsed microwave signals is proposed and demonstrated. It is based on an optoelectronic parametric oscillator (OEPO) ...

Abstract: As the electromagnetic spectrum becomes increasingly crowded, the random frequency and pulse repetition interval agile (RFPA) radar signal is proposed, which can make the transmitted ...

Nanosecond pulsed field ablation, which offers potential benefits, such as reduced muscle contraction, may enable procedures to be performed under local anesthesia.To evaluate the 12-month safety and ...
