The Optical Counterparts of Compact X-ray Binaries in the Globular Cluster NGC 6266
No full textGlobular clusters provide valuable insight into the formation of galaxies and stars. As some of the oldest structures in the Milky Way Galaxy, the stars that make up clusters are some of the oldest witnesses to the formation of our Galaxy, and in some cases, the Universe itself. Additionally, clusters are an excellent source of X-ray information, and the positions of X-ray sources tend to correlate with the positions of globular clusters. As such, studying globular clusters is an excellent way to study galactic compact X-ray binary stars. We present a study of the globular cluster NGC 6266, and perform point-spread photometry on identified stars within using Hubble ACS data in the F435W, F625W, and F658N filters. After measuring HST magnitudes, we have correlated the positions of the identified stars with the position of X-ray sources observed with the Chandra X-ray Observatory, and identified candidate optical counterparts of compact X-ray binaries in the cluster. Using the combined datasets, we have created color-magnitude and color-color diagrams. We present the optical magnitudes and colors of the candidate optical counterparts of 32 X-ray sources, composed of 7 millisecond pulsars, 12 cataclysmic variables, 2 low-mass X-ray binaries, 10 active binaries, 1 black hole, and 6 background objects. 8 fields contain only saturated objects and main-sequence stars, resulting in no classification, although one can be identified as an LMXB system due to its X-ray luminosity and softness without an optical component identification

From Miso to Tray-C: The Impact of Hedonic and Utilitarian Name Preference on Non-Humanoid Service Robots in Restaurants
No full textService robots are become common in the restaurant industry. Robot suppliers recommend business name such robots to increase the likelihood of their acceptance by employees and consumers. The purpose of this study was to investigate the preferences of robot names representing Utilitarian and Hedonic attributes. Our findings show that study respondents had a significantly stronger preference for hedonic names compared to utilitarian names. Names with hedonic attributes were perceived positively and were considered more trustworthy. The name identified through this study was adopted for the service robot at a hospitality management program in the United States. This report also provides practical implications for restaurant operators on how to name their service robots. Future studies can investigate whether hedonic (vs. utilitarian) names can provide higher employee interaction and guest satisfaction in hospitality businesses deploying service robots
