    Wetting films on chemically heterogeneous substrates

    Full text link
    Based on a microscopic density functional theory we investigate the morphology of thin liquidlike wetting films adsorbed on substrates endowed with well-defined chemical heterogeneities. As paradigmatic cases we focus on a single chemical step and on a single stripe. In view of applications in microfluidics the accuracy of guiding liquids by chemical microchannels is discussed. Finally we give a general prescription of how to investigate theoretically the wetting properties of substrates with arbitrary chemical structures.Comment: 56 pages, RevTeX, 20 Figure

    Nearly optimal stationary strategies for the total reward Markov decision process

    No full text
    Consider a Markov decision process with countable state space S and finite action space A. If in state i鈭圫 action a鈭圓 is taken then we get an immediate reward r(i,a) and the system makes a transition to state j with probability p(i,a,j). We assume 危j鈭圫p(i,a,j)=1
