We study a single-item (r, q) inventory system, where r is the reorder point and q is the order quantity. The demand is a compound-Poisson process. We investigate the behavior of the optimal policy parameters and the ...
An Evaluation of the Statistics of Rainfall Extremes in Rain Gauge Observations, and Satellite-Based and Reanalysis Products Using Universal Multifractals

Sun, Xiaoming; Barros, Ana (AMER METEOROLOGICAL SOC, 2010)

Confidence in the estimation of variations in the frequency of extreme events, and specifically extreme precipitation, in response to climate variability and change is key to the development of adaptation strategies. One ...
Stochastic E2F Activation and Reconciliation of Phenomenological Cell-Cycle Models

Lee, Tae J.; You, Lingchong (PUBLIC LIBRARY SCIENCE, 2010)

The transition of the mammalian cell from quiescence to proliferation is a highly variable process. Over the last four decades, two lines of apparently contradictory, phenomenological models have been proposed to account ...
