BACKGROUND In Canada the incidence of Fetal Alcohol Spectrum Disorder (FASD) is estimated to be 1 in 100 live births. FASD is the leading cause of developmental and cognitive disabilities in Canada. Only one study has examined the cost of FASD in Canada. In that study we did not include prospective data for infants under the age of one year, costs for(More)
Automatic object detection is a rapidly evolving area in surveillance and autonomous vehicles. Deformable part model (DPM) is a well-known object detector for its high precision and speed bottleneck. This paper proposes a very fast object detection pipeline based on complementary techniques to accelerate DPM. A recent fast feature pyramid technique is(More)
Well log data are a common source of information for characterizing subsurface environments. A statistical methodology is developed and applied for the interpretation of such data in terms of a multi-state depositional sequence. The well log data is classified into a discrete set of states (e.g., sand, silt, clay) and stratigraphic transitions between these(More)
Connected zones of high hydraulic conductivity in subsurface environments can constitute preferential pathways for contaminant transport and fluid flow. The identification of such pathways is important for well head protection, groundwater monitoring and capture system design for groundwater remediation. Since it is not practical to exhaustively sample the(More)
Subsurface characterization is important for investigations of groundwater contamination as well as petroleum extraction potential. Bore holes or drill logs are a common source of localized stratigraphic information. Sampling and interpolation uncertainties complicate the characterization of the subsurface from these data. Geostatistical methods (Kriging(More)
Transmission of a nuclear polyhedrosis virus (NPV) was examined in uniformaged and uniform- vs mixed-age populations ofHeliothis zea (Boddie) on caged soybean. Larval collections revealed viral disease outbreaks occurred in all treatments following release of infected larvae (Primary infected larvae). Transmission of NPV in uniform-aged populations was(More)
OBJECTIVE To investigate blood lead levels in schoolchildren in two areas of Egypt to understand the current lead pollution exposure and its risk factors, aiming to improve prevention politicies. SUBJECTS AND METHOD This was a cross-sectional study in children (n=400) aged 6-12 years recruited from two areas in Egypt (industrial and urban). Blood lead(More)
