This paper introduces several broad families of designs, such as the play-the-winner rule, randomized play-the-winner rule and its generalization to the multi-arm case, doubly biased coin adaptive design, Markov chain model.展开更多

The order parameter, the susceptibility and the stationary probability distribution have been calculated. By applying the Lee-Yang zeros method of equilibrium phase transitions, we study the distributions of the effective partition function zeros and obtain the same result for the model. Thus, the Lee-Yang theory can be applied to a more general non-equilibrium system.展开更多

To ordinary eyes, they are what they are. But to the sharp, sensitive eyes of a poet, every object has its own beauty, and carries a message deeper than what it seems to do. Through his artistic work, the poet reveals to us the beauty and truth that are hidden from our mediocre eyes, and enables us to enjoy the beauty and see the truth that nature endows to its creations.
