In an irreducible stochastic game, no single player can prevent the stochas-tic process on states from being irreducible, so the other players can ensure that the current state has little effect on events in the distant future. This paper provides a sufficient condition for the folk theorem in irreducible stochastic games with imperfect public monitoring,(More)
We isolated a beta-N-acetylglucosaminidase encoding gene from the filamentous fungus Aspergillus oryzae, and designated it nagA. The nagA gene encoded a polypeptide of 600 amino acids with significant similarity to glucosaminidases and hexosaminidases of various eukaryotes. A. oryzae strain carrying the nagA gene under the control of the improved glaA(More)
The present paper provides a limit characterization of the payoff set supported by belief-free equilibria in repeated games with private monitoring, as the discount factor approaches one and the noise on private information vanishes. Contrary to the conjecture by Ely, Hörner, and Olszewski (2005), in many of the three-or-more player games, the payoff set is(More)
In Saccharomyces cerevisiae, a-cell-specific genes are repressed in MATalpha cells by alpha2/Mcm1, acting in concert with the Ssn6-Tup1 corepressors and the Isw2 chromatin remodeling complex, and nucleosome positioning has been proposed as one mechanism of repression. However, prior studies showed that nucleosome positioning is not essential for repression(More)
This paper studies N player infinitely repeated games with imperfect private monitoring where the discount factor is close to unity. Ely and Valimaki [4] (written as EV below) construct a strategy which makes players indifferent among their actions in each period and show the folk theorem in prisoner's dilemma games with two players when monitoring is(More)

Abstract: The theory of learning in games studies how, which and what kind of equilibria might arise as a consequence of a long-run non-equilibrium process of learning, adaptation and/or imitation. If agents' strategies are completely observed at the end of each(More)
Intensity-modulated proton therapy (IMPT) is expected to improve treatment results with fewer side effects than other proton therapies. The purpose of this study was to evaluate the tumor sites for which IMPT was effective under the same beam calculation conditions by planning IMPT for typical cases treated with passive scattering proton therapy (PSPT). We(More)
