We examined the association between community violence exposure and childhood asthma risk in a multilevel, multimethod, longitudinal study controlling for individual- and neighbourhood-level confounders and pathway variables. Analyses included 2,071 children aged 0-9 yrs at enrolment from the Project on Human Development in Chicago Neighborhoods. Multilevel logistic regression models estimated ...

Point sources (PS) are one of the main contaminants to recovery cosmic microwave background (CMB) signal at small scales, and their detection is important for next generation CMB experiments. We develop a method (PoSeIDoN) based on fully convolutional networks detect PS in realistic simulations, we compare its performance against most used method, Mexican hat wavelet 2 (MHW2). produce simulatio...
