Double jeopardy: Child and school characteristics that undermine school readiness and predict disruptive behavior at school entry
(School Psychology Review, 2010)
Dynamic nonparametric bayesian models for analysis of music
(Journal of the American Statistical Association, 2010-06-01)
The dynamic hierarchical Dirichlet process (dHDP) is developed to model complex sequential data, with a focus on audio signals from music. The music is represented in terms of a sequence of discrete observations, and the ...
Genome-wide scan of copy number variation in late-onset Alzheimer's disease.
(J Alzheimers Dis, 2010)
Alzheimer's disease is a complex and progressive neurodegenerative disease leading to loss of memory, cognitive impairment, and ultimately death. To date, six large-scale genome-wide association studies have been conducted ...
A longitudinal study of epigenetic variation in twins.
DNA methylation is a key epigenetic mechanism involved in the developmental regulation of gene expression. Alterations in DNA methylation are established contributors to inter-individual phenotypic variation and have been ...
Spatial vision in the purple sea urchin Strongylocentrotus purpuratus (Echinoidea).
(J Exp Biol, 2010-01-15)
Recent evidence that echinoids of the genus Echinometra have moderate visual acuity that appears to be mediated by their spines screening off-axis light suggests that the urchin Strongylocentrotus purpuratus, with its higher ...
Coherence potentials: loss-less, all-or-none network events in the cortex.
(PLoS Biol, 2010-01-12)
Transient associations among neurons are thought to underlie memory and behavior. However, little is known about how such associations occur or how they can be identified. Here we recorded ongoing local field potential (LFP) ...
How common are common mental disorders? Evidence that lifetime prevalence rates are doubled by prospective versus retrospective ascertainment.
(Psychol Med, 2010-06)
BACKGROUND: Most information about the lifetime prevalence of mental disorders comes from retrospective surveys, but how much these surveys have undercounted due to recall failure is unknown. We compared results ...
High-field FMRI reveals brain activation patterns underlying saccade execution in the human superior colliculus.
(PloS one, 2010)
BACKGROUND: The superior colliculus (SC) has been shown to play a crucial role in the initiation and coordination of eye- and head-movements. The knowledge about the function of this structure is mainly based on single-unit ...
Bayesian inference of the number of factors in gene-expression analysis: application to human virus challenge studies.
(BMC Bioinformatics, 2010-11-09)
BACKGROUND: Nonparametric Bayesian techniques have been developed recently to extend the sophistication of factor models, allowing one to infer the number of appropriate factors from the observed data. We consider such techniques ...
Parents' Incomes and Children's Outcomes: A Quasi-Experiment.
(Am Econ J Appl Econ, 2010-01)
We examine the role that an exogenous increase in household income due to a government transfer unrelated to household characteristics plays in children's long run outcomes. Children in affected households have higher levels ...
