pulses

Central to this innovation is the ytterbium thin-disk laser, which produces high-power, femtosecond pulses at megahertz repetition rates.

The team hoped to use the light pulses to prevent the bursts by switching off neurons that contained light-sensitive proteins.

A theoretical astrophysicist from the University of Kansas may have solved a nearly two-decade-old mystery over the origins of an unusual "zebra" pattern seen in high-frequency radio pulses from the Crab Nebula.

Those pulses passed through transceivers, encountered the sandpapers, then rebounded back through the system for analysis by the team's learning model.

It was a Lidar survey, a remote sensing technique which fires thousands of radar pulses from a plane and maps objects below using the time the signal takes to return.
