With AR's advanced thermal management techniques, each amplifier model is designed to increase reliability, and comes standard with a remote control package providing flexible integration into any existing system. Optimizing the acoustics of small recital rooms A room's length-to-width ratio is crucial in determining the smoothness of its frequency response. Charles Day A quantum analysis of structured classical light beams The propagation losses of an inhomogeneously polarized light beam uniquely predict the behavior of other beams in a noisy channel. Richard J. Fitzgerald Advertisement THE SLICE-DHV DUAL-CHANNEL PZT CONTROLLER AND HV AMP The SLICE-DHV features low-noise high-bandwidth control of piezoelectric transducers and other voltage-controlled devices. With less than 0.5 mV rms noise and bandwidth up to 1 MHz, precise control over pulse repetition rates, ULE cavity lengths, grating angles, and other critical motions and positioning requirements are at your command. FROM THE VAULT: May 1993 Goals for the federal role in science and technology The arrival of a new administration in Washington raises once more the question of setting priorities for science and technology. Ralph E. Gomory Webinar Switching on Stars at the Dawn of Time The Era of the First Stars is the mysterious time when the first stars burst into life, when darkness finally gave way to light. This talk will unveil our pursuit of these incredible stars, and offers a first-hand look at the immense telescopes about to come on line to peer into the past. Register now. Social bubbles reduce risk of COVID-19 superspreader events When a small group of carriers produces most infections, reducing the size of social circles becomes an effective mitigation strategy. Heather M. Hill You might have missed A comprehensive theoretical survey of nuclei Ab initio calculations of the interactions between nucleons seek to predict whether various isotopes can hold on to all their nucleons. Andrew Grant Whitepaper Technology leaps in quantum sensing In this whitepaper we give an overview of the current proposed solutions for quantum sensors based on NV center magnetometry. Read it now. FROM THE MARCH MAGAZINE Quantum firmware and the quantum computing stack Integrated quantum-control protocols could bridge the gap between abstract algorithms and the physical manipulation of imperfect hardware.
