A defect-enhanced silicon photodiode and heater are integrated with and used to thermally stabilize a microring modulator. These optoelectronic components are interfaced with external control circuitry to create a closed-looped feedback system for thermally stabilizing the microring modulator. The thermal stabilization system enables the microring modulator(More)
X-ray absorption (or more properly, x-ray attenuation) techniques have been applied to study the moisture movement in and moisture content of materials like cement paste, mortar, and wood. An increase in the number of x-ray counts with time at a location in a specimen may indicate a decrease in moisture content. The uncertainty of measurements from an x-ray(More)
Excitatory and inhibitory responses of sympathetic discharge were recorded in single renal postganglionic neurons of rabbits anaesthetized with urethane and chloralose. The animals were vagotomized and had transected aortic nerves. Responses were elicited by single volleys in the aortic C-fibres. Excitatory responses consisted in short-lasting increase in(More)
