High purity NaI(Tl) scintillator to search for dark matter

Kavli Affiliate: Kunio Inoue | First 5 Authors: Ken-Ichi Fushimi, Hiroyasu Ejiri, Ryuta Hazama, Haruo Ikeda, Kunio Inoue | Summary: A high purity and large volume NaI(Tl) scintillator was developed to search for cosmic dark matter. The required densities of radioactive impurities (RIs) such as U-chain, Th-chain are less than a few ppt to establish […]

Markov Chains and Unambiguous Automata

Kavli Affiliate: David Muller | First 5 Authors: Christel Baier, Stefan Kiefer, Joachim Klein, David Müller, James Worrell | Summary: Unambiguous automata are nondeterministic automata in which every word has at most one accepting run. In this paper we give a polynomial-time algorithm for model checking discrete-time Markov chains against omega-regular specifications represented as unambiguous […]
