We consider theories with a spontaneously broken gauged R-symmetry, which can only occur in supergravity models. These give rise to cosmic R-strings upon which gravitino zero modes can exist. We construct solutions to the Rarita-Schwinger spin-3/2 equation describing the gravitino in the field of these cosmic strings and show that under some conditions these solutions may give rise to gravitino...

BACKGROUND This study characterizes the intake of sweetened beverages and establishes whether economic inequalities in their consumption exists. METHODS Ecological study. Mixed methods using food frequency questionnaire and inequality indices. Based on the National Nutrition Survey, Colombia, 2010. The sweetened beverage intake of 17,514 subjects in 33 geodemographic units was estimated with ...

Crowd-sourced biodiversity databases provide easy access to data and images for ecological education research. One concern with using publicly sourced databases; however, is the quality of their images, taxonomic descriptions, geographical metadata. The method presented in this paper attempts address a suite pipelines evaluate consistency, how well geo-tagging fits known distributions, image cr...

The idea that the whole can represent more than the sum of the parts is of fundamental importance in science, as illustrated in complexity theory: the emergent behavior of many complex systems cannot simply be derived from their individual components. In quantum mechanics, this phenomenon appears in a particularly subtle form: certain physical quantities, relevant to the description of quantum ...
