Sorghum bicolor is a close relative of maize and is a staple crop in Africa and much of the developing world because of its superior tolerance of arid growth conditions. We have generated sequence from the hypomethylated portion of the sorghum genome by applying methylation filtration (MF) technology. The evidence suggests that 96% of the genes have been(More)
Nosocomial (i.e., hospital-acquired) infections are a major cause of morbidity and mortality in the United States and throughout the world. Therefore, understanding, mediating, and limiting contagious infections are important problems, even in clinical settings. Contact networks of healthcare workers and patients provides a vehicle for modeling the spread(More)
OBJECTIVE To explore how hand hygiene observer scheduling influences the number of events and unique individuals observed. DESIGN We deployed a mobile sensor network to capture detailed movement data for 6 categories of healthcare workers over a 2-week period. SETTING   University of Iowa Hospital and Clinic medical intensive care unit (ICU). METHODS(More)
Populating large-scale structured databases from unstructured sources is a critical and challenging task in data analytics. As automated feature engineering methods grow increasingly prevalent, constructing sufficiently large labeled training sets has become the primary hurdle in building machine learning information extraction systems. In light of this, we(More)
This paper describes a method of using Craig list personal ads to better understand the movement behavior of anonymous, casual sex-seeking individuals within the men-who-have-sex-with-men community. Given recent dramatic increases in HIV and sexually transmitted disease within this community, gaining insight into how sexual networks connect neighborhoods(More)
Anonymous sexual encounters negotiated via the Internet present many challenges to public health officials addressing outbreaks of sexually transmitted infections. The anonymity and potential geographic scale of encounters weaken traditional tools like contact tracing and partner notification. These developments complicate interventions within the men who(More)
reproduction in any medium, provided the original work is properly cited. Objective This paper constructs an authorship-linked collection or corpus of anonymous, sex-seeking ads found on the classifieds website Craigslist. This corpus is then used to validate an authorship attribu-tion approach based on identifying near duplicate text in ad clusters,(More)
We present SWELLSHARK, a framework for building biomedical named entity recognition (NER) systems quickly and without hand-labeled data. Our approach views biomedical resources like lexicons as function primitives for autogenerating weak supervision. We then use a generative model to unify and denoise this supervision and construct large-scale,(More)
