    Quiescence: a mechanism for escaping the effects of drug on cell populations

    Get PDF
    We point out that a simple and generic strategy to lower the risk for extinction consists in the developing a dormant stage in which the organism is unable to multiply but may die. The dormant organism is protected against the poisonous environment. The result is to increase the survival probability of the entire population by introducing a type of zero reproductive fitness. This is possible, because the reservoir of dormant individuals act as a buffer that can cushion fatal fluctuations in the number of births and deaths which without the dormant population would have driven the entire population to extinction.Comment: 18 pages and 9 figure

    Area limit laws for symmetry classes of staircase polygons

    Full text link
    We derive area limit laws for the various symmetry classes of staircase polygons on the square lattice, in a uniform ensemble where, for fixed perimeter, each polygon occurs with the same probability. This complements a previous study by Leroux and Rassart, where explicit expressions for the area and perimeter generating functions of these classes have been derived.Comment: 18 pages, 3 figure

    Atmospheric and Oceanographic Information Processing System (AOIPS) system description

    Get PDF
    The development of hardware and software for an interactive, minicomputer based processing and display system for atmospheric and oceanographic information extraction and image data analysis is described. The major applications of the system are discussed as well as enhancements planned for the future

    Fluctuations of 1/f1/f noise and the low frequency cutoff paradox

    Full text link
    Recent experiments on blinking quantum dots and weak turbulence in liquid crystals reveal the fundamental connection between 1/f1/f noise and power law intermittency. The non-stationarity of the process implies that the power spectrum is random -- a manifestation of weak ergodicity breaking. Here we obtain the universal distribution of the power spectrum, which can be used to identify intermittency as the source of the noise. We solve an outstanding paradox on the non integrability of 1/f1/f noise and the violation of Parseval's theorem. We explain why there is no physical low frequency cutoff and therefore cannot be found in experiments.Comment: 5 pages, 2 figures, supplementary material (4 pages

    Bagchi's Theorem for families of automorphic forms

    Full text link
    We prove a version of Bagchi's Theorem and of Voronin's Universality Theorem for family of primitive cusp forms of weight 22 and prime level, and discuss under which conditions the argument will apply to general reasonable family of automorphic LL-functions.Comment: 15 page
