TL;DR: From life course, cumulative inequality, and developmental perspectives, child food insecurity may have long-term effects, including on risk of obesity, which is detrimental for children.
Abstract: Coexistence of food insecurity and obesity is expected given that both are consequences of economic and social disadvantage. Food insecurity and obesity are positively associated in adult women but not men. There is some evidence of association in adolescents, but mixed results for children. Distinct from adults, children experience cognitive, emotional, and physical awareness of food insecurity and take responsibility for it by participating in adult strategies, initiating their own strategies, and taking action to obtain additional food or money for food. Food insecurity is detrimental for children, being associated with behavior problems, disrupted social interactions, compromised school performance and attendance, poor dietary intake and physical activity, altered daily activities, and poor health. Some of these outcomes increase the risk of developing obesity. From life course, cumulative inequality, and developmental perspectives, child food insecurity may have long-term effects, including on risk of obesity. Pediatricians can help identify and respond to children who are food-insecure and at risk of obesity.

TL;DR: In this article, the minimal geometric deformation approach, which has been successfully used to generate exact interior solutions to Einstein's field equations for static braneworld stars with local and nonlocal bulk terms, is used to obtain the branworld version of the Schwarzschild's interior solution.
Abstract: In the context of the Randall–Sundrum braneworld, the minimal geometric deformation approach, which has been successfully used to generate exact interior solutions to Einstein's field equations for static braneworld stars with local and nonlocal bulk terms, is used to obtain the braneworld version of the Schwarzschild's interior solution. Using this new solution, the behavior of the Weyl functions is elucidated in terms of the compactness for different stellar distributions.

TL;DR: This work analyzes the privatized rural postman problem, which is the edge version of the traveling salesman problems with profits, and shows that it is NP-hard, its relation with known and new problems, and special cases with good algorithms.

TL;DR: The presence of a putative pathogenic ciliate protozoan of the genus Halofolliculina was found on 10 hard coral species at the National Parks of Los Roques and Morrocoy, Venezuela, suggesting it could be a new threat to the coral reefs of this region.
Abstract: This is the first report of a putative pathogenic ciliate protozoan that has been associated with Caribbean corals. Previously, only 2 species of the phylum Ciliophora had been linked to coral diseases, and they were exclusive to the Indo-Pacific region. In this study, a ciliate of the genus Halofolliculina was found on 10 hard coral species at the National Parks of Los Roques and Morrocoy, Venezuela. The general morphology of this ciliate is very similar to that of Halofolliculina corallasia from the Indo-Pacific, which is known to cause skeletal eroding band. None of the other 31 genera in the family Folliculinidae are known to cause diseases in corals or in any other animal species. The presence of this ciliate, which shows a prevalence comparable to that of other epizootics in the Caribbean, suggests it could be a new threat to the coral reefs of this region.
