The coalescent process is a widely used approach for inferring the demographic history of a population, from samples of its genetic diversity. Several parametric and non-parametric coalescent inference methods, involving Markov chain Monte Carlo, Gaussian processes, and other algorithms, already exist. However, these techniques are not always easy to adapt and apply, thus creating a need for al...

BACKGROUND At present, there is no widely accepted classification system for partial-thickness rotator cuff tears, and as a result, optimal treatment remains controversial. PURPOSE To examine the interobserver reliability and accuracy of classifying partial rotator cuff tears using the Snyder classification system. We hypothesized that the Snyder classification would be reproducible with high...

Juvenile delinquency, adolescent antisocial behavior, and conduct problems represent a significant emphasis in extant social science research (Mallett & Stoddard-Dare, 2010; Maschi, Smith Hatcher, Schwalbe, & Scotto Rosato, 2008). This focus may be due, in part, to the relationship between antisocial behaviors and conduct problems, including diagnosable mental health disorders (Shufelt & Cocozz...

Using the parametrized relativistic particle we obtain the noncommutative Snyder space-time. In addition, we study the consistency conditions between the boundary conditions and the canonical gauges that give origin to noncommutative theories. Using these results we construct a first order action, in the reduced phase-space, for the Snyder particle with momenta fixed on the boundary. Pacs: 11.1...
