Status of the Daya Bay Reactor Neutrino Oscillation Experiment
The last unknown neutrino mixing angle is one of the
fundamental parameters of nature; it is also a crucial parameter for
determining the sensitivity of future long-baseline experiments aimed to study
CP violation in the neutrino sector. Daya Bay is a reactor neutrino oscillation
experiment designed to achieve a sensitivity on the value of
to better than 0.01 at 90% CL. The experiment consists of
multiple identical detectors placed underground at different baselines to
minimize systematic errors and suppress cosmogenic backgrounds. With the
baseline design, the expected anti-neutrino signal at the far site is about 360
events per day and at each of the near sites is about 1500 events per day. An
overview and current status of the experiment will be presented.Comment: 4 pages, 4 figures. Proceedings of the 35th International Conference

The demand for lottery expenditure in Taiwan: a quantile regression approach
This paper is a pioneering attempt to apply the quantile regression method (QRM) to the demand for lottery expenditure in order to consider the extreme behavior of lottery expenditure as well as clarify the diverse results obtained from previous studies on lottery expenditure. The results of this study reveal that there exists a complementary correlation both between benevolent donations and lottery expenditure, and between entertainment expenditure and lottery expenditure. By contrast, the results from using OLS reveal that benevolent donations do not have a significant impact on lottery expenditure and that entertainment expenditure does not have a negative impact on lottery expenditure. Besides, expenditure on cigarettes and alcohol is found to have a positive impact on lottery expenditure, which coincides with the results of Balabanis (2002).
