We present a database of copy number variations (CNVs) detected in 2026 disease-free individuals, using high-density, SNP-based oligonucleotide microarrays. This large cohort, comprised mainly of Caucasians (65.2%) and African-Americans (34.2%), was analyzed for CNVs in a single study using a uniform array platform and computational process. We have(More)
OBJECTIVE An opportunity exists to use increasingly prevalent electronic health records to efficiently gather immunization, clinical, and demographic data to assess and subsequently reduce barriers to immunization. The objective of this study was to use data entered at the point of care within an electronic health record to identify factors that predispose(More)
The Resonance Ultrasonic Vibrations (RUV) technique was developed for in-line non-destructive crack detection in full-size silicon wafers and solar cells. The RUV methodology relies on deviation of the resonance frequency response curve measured on a wafer with peripheral or bulk millimeter-length crack and on identical non-cracked wafers. Three RUV(More)
A temporary increase in the conductivity of aluminum oxide sputter deposited on the surface of aluminum wafers was made by exposure to vacuum ultraviolet ~VUV! radiation produced by a synchrotron light source. The oxide was charged, either positively or negatively, by exposure to a nonreactive inductively coupled plasma, under typical plasma processing(More)
Paper presents the comparative investigation of photoluminescence and Raman scattering spectra of pure amorphous silicon films and amorphous silicon films with different size Si nanocrystallites. Several PL bands in the IR spectral range with maxima at 0.90, 0.98, 1.14 and 1.36 eV have been revealed in studied samples. The 0.90–0.98 eV PL bands are(More)
The influence of external factors, viz. reaction mixture temperature, presence of low- and high-molecular (tween-20) organic compounds, urea and the solution high ionic strength on kinetic properties of PGH synthetase has been studied. Some factors (high ionic strength, addition of organic compounds) were found to slow down irreversible inactivation of PGH(More)
INTRODUCTION Low-income child populations remain under-vaccinated. Our objective was to determine differences in the relative importance of maternal health literacy and socio-demographic characteristics that often change during early childhood on up-to-date (UTD) immunization status among a low-income population. METHODS We performed secondary data(More)
This paper presents results of porous Sic characterization using photoluminescence, Raman scattering and Atomic Force Microscopy. A comparative optical spectroscopy study on bulk Sic and porous Sic layers has shown a number of new features specific to nano-crystallite materials. The role of these effects on optical spectroscopy data in porous Sic accessed(More)
A novel method, computer TV morphodensitometry, was used to evaluate the effects of low-dose irradiation on peripheral blood lymphocytes from children affected by the Chernobyl disaster. This method uses digitized images to detect and measure changes in chromatin shape and density and to produce two-dimensional and three-dimensional pictures. Images can(More)
This retrospective cohort study aimed to describe antipyretic use among healthy patients in a pediatric emergency department (ED) with nonurgent fever defined as: triage level 4 or 5, chief complaint fever or temperature 38°C to 39°C, and otherwise normal vital signs, and determine if antipyretic administration is associated with increased ED length of stay(More)
