Comparison of guided endodontic access with and without pin fixation in 3D printed teeth with simulated pulp canal obliteration
… of iatrogenic errors. Guided endodontic access (GEA) combines information from a cone-beam computed tomography (CBCT) scan with an intra-oral scan to create a stent. GEA stents with or without fixation pins have been shown to be successful in accurately negotiating a RCS with PCO. Objective: …

Dynamic-programming approaches to single-and multi-stage stochastic knapsack problems for portfolio optimization
This thesis proposes new methods, based on dynamic programming, for solving certain single-stage and multi-stage integer stochastic knapsack problems. These problems model stochastic portfolio optimization problems (SPOPs) which assume deterministic unit weight, and normally distributed unit return …

Population Genomics of the Sugar Kelp Saccharina latissima
… Results from genotype-environmental association (GEA) tests highlighted the influences of environmental heterogeneity, as well as oceanographic isolation, in driving multi-scale patterns of local adaptation. Comparisons of the two genomic datasets highlighted contrasting levels of polymorphism and …
