We examined the relationship between a remote history of concussions with current symptoms of depression in retired professional athletes. Thirty retired National Football League (NFL) athletes with a history of concussion and 29 age- and IQ-matched controls without a history of concussion were recruited. We found a significant correlation between the number of lifetime concussions and depressi...

Recent redescriptions of most members of the Oxyuridae Cobbold, 1864 parasitic in primates revealed that they share following derived characters: sexual dimorphism of lateral alae (single-crested in the males, double-crested in the females); in males a second pair of genital papillae always surrounded by strongly cuticularized rings; in females, uterine tube divided into 2 parts by a cellular w...

The Supreme Court’s “one person, one vote” standard imposes a measure of equality onto any individual’s ability to influence an election’s outcome. The Court has been reluctant to attach this standard to other election resources, like campaign expenditures, despite the fear that money will bring about the appearance of impropriety in democratic decision making. Recently, the Court reasserted th...

This article considers ultrahigh-dimensional forecasting problems with survival response variables. We propose a two-step model averaging procedure for improving the accuracy of true conditional mean variable. The first step is to construct class candidate models, each low-dimensional covariates. For this, feature screening developed separate active and inactive predictors through marginal Buck...

In previous work, a new adaptive meshfree advection scheme for numerically solving linear transport equations has been proposed. The scheme, being a combination of an adaptive semi-Lagrangian method and local radial basis function interpolation, is essentially a method of backward characteristics. The adaptivity of the meshfree advection scheme relies on customized rules for the refinement and ...

that the disorder involves atypical development of brain connectivity, several open questions remain with regard to the precise nature of these atypicalities. A limitation of the current neuroimaging literature is a focus on adulthood autism, with recent work beginning to examine late childhood and adolescence (Uddin et al., 2013). In this issue of EBioMedicine, Buckley and colleagues contribut...

This paper describes how the bootstrap approach to statistics can be applied to the evaluation of IR effectiveness metrics. More specifically, we describe straightforward methods for comparing the discriminative power of IR metrics based on Bootstrap Hypothesis Tests. Unlike the somewhat ad hoc Swap Method proposed by Voorhees and Buckley, our Bootstrap Sensitivity Methods estimate the overall ...

This paper compares 14 information retrieval metrics based on graded relevance, together with 10 traditional metrics based on binary relevance, in terms of stability, sensitivity and resemblance of system rankings. More specifically, we compare these metrics using the Buckley/Voorhees stability method, the Voorhees/Buckley swap method and Kendall’s rank correlation, with three data sets compris...
