		In this later study, the RFRs used were 425-MHz pulses of 125, 250, 500, 1000, and 2000 microseconds at 27 pps (respective duty cycles of 0.0034, 0.0068, 0.0135, 0.027, and 0.054) and 2.5-microsecond pulses of 8.9-GHz RFR at 400 pps (duty cycle 0.001).
		The RFR stimuli were pulses, 0.5-32 microseconds in duration, of 918-MHz or 2.45-GHz RFR from a horn or aperture 8 cm from the occipital pole of the cat.
		For pulses of constant peak amplitude, loudness was perceived to increase with duration from 5 to 50 microseconds, decrease from 70 to 100 microseconds, and increase again for 100 microseconds and upward.

	High Speed Photography
		In the microsecond region, an improved spark gap has argon gas blown into it via a hole drilled along the axis of one electrode giving a longer gap for the same voltage, and thus more light output and a repeatable line source particularly suitable for schlieren photography.
		With optically (dye-) sensitized emulsions, a further loss of speed occurs around 1 microsecond exposure, and is believed to be due to the sensitizing dyes.
		A series of 1 microsecond exposures of the arc in a typical tube made with a magneto-optic shutter shows that the arc starts as a narrow filament adjacent to the flash-tube wall on the side of the external triggering electrode.

	Split-faced study compares pulse widths - Cosmetic Surgery Times
		The N-Lite Laser (350 microsecond) had a 5-mm spot size while the V-Star (450 microsecond) had a 10-mm spot size.
		However, there was also a significant patient population that demonstrated a preference for the side treated with the longer 450 microsecond pulsed dye laser.
		As another control part of the study, patients were randomly assigned treatment of the forehead and cheek with the 450 microsecond laser to assess improvement, both subjectively and objectively.

	Accurate pyrometry with microsecond time resolution
		The development of pyrometry with time resolution in the microsecond range is required by high-speed thermophysical property experiments with millisecond duration.
		The general design criteria of a high-speed pyrometer with such a resolution are discussed and the contribution of several parameters is analysed to optimise the pyrometer performance with respect to the temperature-time characteristic of the event to be measured.
		Salient features of a pyrometer built on the basis of these criteria are described, with the details of the procedures necessary for its calibration.

	Science of Folding@Home
		Unfortunately, proteins fold on the tens of microsecond timescale (10,000 nanoseconds).
		Our group has developed multiple new ways to simulate protein folding which can break the microsecond barrier by dividing the work between multiple processors in a new way -- with a near linear speed up in the number of processors.
		Thus, with power of Folding@Home (over 100,000 processors), we have successfully smashed the microsecond barrier, simulating milliseconds of folding time and helped to unlock the mystery of how proteins fold.

		Scheduling jitter can be limited to less than two microseconds, the company claims, using its "processor reservation" technology.
