    Straightening Beta: Overdispersion of Lethal Chromosome Aberrations following Radiotherapeutic Doses Leads to Terminal Linearity in the Alpha–Beta Model by Igor Shuryak, Bradford D. Loucas, Michael N. Cornforth

    Published 2017-12-01
    “…Here, we show that the distribution of lethal chromosomal lesions among individual human cells (lymphocytes and fibroblasts) exposed to gamma rays and X rays is somewhat overdispersed, compared with the Poisson distribution. Further, we show that such overdispersion affects the predicted dose response for cell survival (the fraction of cells with zero lethal lesions). …”

    Estimation of the Tapered Gutenberg-Richter Distribution Parameters for Catalogs with Variable Completeness: An Application to the Atlantic Ridge Seismicity by Matteo Taroni, Jacopo Selva, Jiancang Zhuang

    Published 2021-12-01
    “…Differently from other estimation methods for catalogs with a variable completeness, available for example for the classical truncated Gutenberg-Richter distribution, our approach does not need the assumption on the distribution of the number of events (usually the Poisson distribution). We test the methodology checking the consistency of parameter estimations with synthetic catalogs generated with multiple completeness levels. …”

    Published 2017-04-01
    “…Our proposed algorithm uses a maximum likelihood method with image regularization as the basic principle, and constructs the joint log likelihood function for multi-frame AO images based on a Poisson distribution model. To begin with, a frame selection method based on image variance is applied to the observed multi-frame AO images to select images with better quality to improve the convergence of a blind deconvolution algorithm. …”

    Published 2021-11-01
    “…The results obtained show that the pressure distribution has a Gaussian behavior and that the hours of service have a Poisson distribution. HIGHLIGHTS A pressure range between 7 and 30 mwc is essential for user satisfaction.; A minimum of 6 hours of service is recommended in IWS systems.; The behavior of service hours is not linear but exponential in its effect on the satisfaction of demand.; Multivariate analysis is an adequate technique to facilitate the decision making in a water supply system.; Pressure variation has normal behavior regardless of the number of hours supplied…”
