Cryogenic scintillators in searches for extremely rare events
Inorganic scintillators are important elements of a new type of cryogenic phonon scintillation detector (CPSD) being developed for single particle detection. These detectors, exhibiting superior energy resolution and the ability to identify the type of interaction in an event, are considered to be the next generation of instrumentation in the search for extremely rare events. This paper present...
متن کاملOptimizing persistent random searches.
We consider a minimal model of persistent random searcher with a short range memory. We calculate exactly for such a searcher the mean first-passage time to a target in a bounded domain and find that it admits a nontrivial minimum as function of the persistence length. This reveals an optimal search strategy which differs markedly from the simple ballistic motion obtained in the case of Poisson...
متن کاملStatistical Monitoring of Rare Events in Healthcare
There are miscellaneous quality characteristics in healthcare which are interested to be monitored. However, monitoring each characteristic needs a special statistical method. There are some characteristics with very small incidence rates that it’s usually considered not to be necessary to monitoring them, since their incidence rates are so small that p and np charts are not able to monitor t...
متن کاملKeeping rare events rare
It has been claimed that corpus-based TTS is unworkable because it is not practical to include representative units to cover all or most of the combinations of segments and prosodic characteristics found in general texts, a problem characterized as Large Numbers of Rare Events (LNRE). We argue that part of this problem is in its formulation, and that a closer look, including investigations into...
متن کاملBias-corrected Confidence Intervals for Rare Searches
We discuss the problem of selecting an optimal cut and then finding confidence limits based on that cut. Even when performing a blind analysis this may lead to a bias in the limits because the cut selected may be optimal for a real or simulated data set with limited statistics and thus may be sensitive to fluctuations in this data set. We propose to use a variant of the bootstrap to find the li...
