While indel rate variation has been observed and analyzed in detail, it is not taken into account by current indel-aware phylogenetic reconstruction methods. In this work, we introduce a continuous time stochastic process, the geometric Poisson indel process, that generalizes the Poisson indel process by allowing insertion and deletion rates to vary across sites. We design an efficient algorithm for computing the probability of a given multiple sequence alignment based on our new indel model.

The secondary goals were to identify factors associated with missing the benchmark and to determine whether the benchmark was associated with improved 30-day patient outcomes. Patients aged 60 years or older who underwent hip fracture surgery between 2005 and 2013 were identified from the ACS-NSQIP database.

We hypothesize that the introduction of less toxic chemotherapy has increased treatment of advanced non-small-cell lung cancer resulting in improved survival.
Methods: The BC Cancer Agency provides cancer care to 4.
Objectives: The effect of ethnicity on nasopharyngeal cancer (NPC) outcomes is unclear. This retrospective analysis examines survival and the impact of concurrent chemoradiation (chemoRT) among Asian and non-Asian patients.
Methods: Subjects included 380 consecutive patients with NPC treated at a Canadian institution from 2000 to 2009.
Introduction: The IPASS trial demonstrated superior progression free survival for Asian, light/never smoking, advanced, pulmonary adenocarcinoma patients treated with first-line gefitinib compared to carboplatin/paclitaxel, of which 59% of those tested were epidermal growth factor receptor (EGFR) mutation positive. In IPASS 39% of gefitinib treated patients went on to receive platin based polychemotherapy. We hypothesized that in a population-based setting fewer patients receive second-line platin based chemotherapy than those enrolled in a clinical trial.
