Nicotine stimulus expectancy differentially affects reaction time in healthy nonsmokers and smokers depending on sex: a pilot study.
Effects of nicotine on neurocognitive performance have been shown but are influenced by nonpharmacological expectancies in smokers, whereas there is little knowledge about expectancy effects inExpand

Stabilizing a Fabry-Perot etalon to 3 cm/s for spectrograph calibration
We present a method of frequency stabilizing a broadband etalon that can serve as a high-precision wavelength calibrator for an Echelle spectrograph. Using a laser to probe the Doppler-free saturatedExpand

Rubidium-traced white-light etalon calibrator for radial velocity measurements at the cm s−1 level
Abstract. We report on the construction and testing of a vacuum-gap Fabry–Pérot etalon calibrator for high precision radial velocity spectrographs. Our etalon is traced against a rubidium frequencyExpand
