Purpose Cataract blindness accounts for a substantial proportion of blindness worldwide. Understanding the correlations between national levels of socioeconomic development with the quantity and quality of cataract surgery may provide insight for the prioritization and resource allocation for blindness prevention programs. Methods The relationships between human development index (HDI), gross...

We study N N spinless fermions in their ground state confined by an external potential one dimension with long range interactions of the general Calogero-Sutherland type. For some choices this system maps to standard random matrix ensembles for values Dyson index \beta display="inline">...

OBJECTIVES To identify factors associated with children's motor skills. DESIGN Cross-sectional. METHODS Australian preschool-aged children were recruited in 2009 as part of a larger study. Parent proxy-report of child factors (age, sex, parent perception of child skill, participation in unstructured and structured activity), self-report of parent factors (confidence in their own skills to s...

OBJECTIVE Although there is growing awareness of the long-term cognitive effects of repetitive mild traumatic brain injury (rmTBI; eg, sports concussions), whether repeated concussions cause long-term cognitive deficits remains controversial. Moreover, whether cognitive deficits depend on increased amyloid β deposition and tau phosphorylation or are worsened by the apolipoprotein E4 allele rema...

OBJECTIVES The purpose of this study was to examine the effectiveness of a 30-week fundamental motor skill program in typically developing young children and to investigate possible sex differences. DESIGN A multicenter quasi experimental design was set up for this study which involved 992 children aged 3-8 years. METHODS All participants received their typical Physical Education curriculum...

We consider the 3D quantum BBGKY hierarchy which corresponds to the N -particle Schrödinger equation. We assume the pair interaction is N3β−1V (N•). For interaction parameter β ∈ (0, 23 ), we prove that, as N →∞, the limit points of the solutions to the BBGKY hierarchy satisfy the space-time bound conjectured by Klainerman-Machedon [37] in 2008. This allows for the application of the Klainerman...

We propose marginal integration estimation and testing methods for the coefficients of varying-coefficient multivariate regression models. Asymptotic distribution theory is developed for the estimation method, which enjoys the same rate of convergence as univariate function estimation. For the test statistic, asymptotic normal theory is established. These theoretical results are derived under t...

A male Thoroughbred fetus was aborted on day 251 of pregnancy. Gross and histological examinations detected systemic granulomatous lesions in many superficial and visceral lymph nodes and organs including the liver, tonsils, lungs, thymus, spleen, right thyroid gland and gastrointestinal tract, and suppurative placentitis, pyogranulomatous amnionitis and intralesional acid-fast bacilli were als...

Background: Measurement of gross , gross activities, and cosmogenic beryllium-7 (7Be) concentrations were made both daily and weekly during the years 2001- 2004 from samples of atmospheric aerosols filtered from the air at Tehran Nuclear Research Center (35 41' N) and Zahedan (28 29' N). Materials and Methods: Weekly aerosol samples were collected with the high-volume air samplers on cellul...

Potato crops are one of the main sources income for farmers living in Bekaa Valley Lebanon. Given high sensitivity potatoes to water stress, shortages can cause considerable losses terms potato yield and quality. To overcome this challenge, use water-saving technologies such as micro-irrigation systems very important. However, adoption technique remains quite low among region, who still ordinar...
