BACKGROUND Maternal race/ethnicity, age, and socioeconomic status (SES) are important factors determining birth outcome. Previous studies have demonstrated that, teenagers, and mothers with advanced maternal age (AMA), and Black/Non-Hispanic race/ethnicity can independently increase the risk for a poor pregnancy outcome. Similarly, public insurance has been(More)
Semi-Markov decision processes are used to formulate many control problems and also play a key role in hierarchical reinforcement learning. In this chapter we show how to translate the decision making problem into a form that can instead be solved by inference and learning techniques. In particular, we will establish a formal connection between planning in(More)
Background. To ensure an adequate supply of blood, collection centers must design campaigns that successfully recruit and maintain an active donor pool. Understanding factors that motivate and deter individuals from donating may help centers develop targeted recruitment campaigns. These factors among high school aged blood donors have not yet been fully(More)
The cohesion of replicated sister chromatids promotes chromosome biorientation, gene regulation, DNA repair, and chromosome condensation. Cohesion is mediated by cohesin, which is deposited on chromosomes by a separate conserved loading complex composed of Scc2 and Scc4 in Saccharomyces cerevisiae. Although it is known to be required, the role of Scc2/Scc4(More)
In this paper, we address parameter estimation for hybrid dynamical systems with state-dependent events and time-delayed parametric switching. Parameter estimation of hybrid systems can aid in system identification, model refinement, and contingency and stability analysis in various fields, including chemical, electrical, and power systems engineering. We(More)
