Newborn boys have higher morbidity and mortality than girls. Several studies have shown that male newborn sex is an independent risk factor for adverse outcome. The specific mechanisms leading to the increased risks for newborn boys are not known. However, several sex-specific reactions and physiologic responses have been described in both the fetus and newborn infants. Some of these differences p
Saccharomyces cerevisiae ferments hexoses in lignocellulosic hydrolysates under anaerobic conditions with high rates and ethanol yields. However, S. cerevisiae is naturally unable to utilize the pentose fraction of the hydrolysates. Xylose is the most abundant pentose sugar, and although recombinant S. cerevisiae strains capable of ethanolic xylose fermentation have been obtained through metabolic

This thesis is based on five papers (A-E) treating estimation methods for unbounded densities, random fields generated by Lévy processes, behavior of Lévy processes at level crossings, and a Markov random field mixtures of multivariate Gaussian fields. In Paper A we propose an estimator of the location parameter for a density that is unbounded at the mode. The estimator maximizes a modified lik
