— The use of high speed adaptive secondary mirrors (AS) in cassegrain or gregorian telescopes shows high optical efficiency as well as the possibility to make Adaptive Optics (AO) available at all foci. After 4 years of extensive and successful use of a 336-actuator AS (MMT336) at the Multi Mirror Telescope (MMT), the need for faster control methods of the(More)
In this paper, a novel method for designing a model-based two-degree-of-freedom control structure for high speed position control of large deformable mirrors with voice coil actuators is presented. Both global feedforward and glocal (decentralized accounting for global dynamics) feedback control is included allowing for separately designing tracking(More)
Previous research supports the activational role of central cholinergic mechanisms in rodent female sexual behavior. This experiment examined if similar central cholinergic mechanisms facilitate female rhesus monkey (Macaca mulatta) sexual behavior. Eight ovariectomized female rhesus monkeys received daily estradiol benzoate priming (5 microg/kg, SC). After(More)
