Many different methods have been proposed for the analysis of cluster randomized trials (CRTs) over the last 30 years. However, the evaluation of methods on overdispersed count data has been based mostly on the comparison of results using empiric data; i.e. when the true model parameters are not known. In this study, we assess via simulation the performance(More)
A 14-year-old female presented with common clinical findings for a rare primary intracardiac tumor. Primary cardiac tumors are rare in all age groups, occurring in 0.05% of routine postmortem examinations. Pediatric primary cardiac tumors are likewise uncommon, with the most common being a rhabdomyoma. Atrial myxomas occur infrequently in the pediatric age(More)
Approved for public release; distribution is unlimited. Abstract: This report identifies rapidly colonizing and resilient grasses/forbs that are tolerant to range-relevant contaminants, with emphasis on TNT and RDX. A literature review identified herbaceous plant species with characteristics that make them potential candidates for use on ranges for(More)
Protease-activated receptor 1 (PAR1) is a G protein-coupled receptor (GPCR) for thrombin and promotes inflammatory responses through multiple pathways including p38 mitogen-activated protein kinase signaling. The mechanisms that govern PAR1-induced p38 activation remain unclear. Here, we define an atypical ubiquitin-dependent pathway for p38 activation used(More)
The Influenza Research Database (IRD) is a U.S. National Institute of Allergy and Infectious Diseases (NIAID)-sponsored Bioinformatics Resource Center dedicated to providing bioinformatics support for influenza virus research. IRD facilitates the research and development of vaccines, diagnostics and therapeutics against influenza virus by providing a(More)
Research has been conducted to develop alternatives to chemically amplified 193 nm photoresist materials that will be able to achieve the requirements associated with sub-32 nm device technology. New as well as older photoresist design concepts for non-chemically amplified 193 nm photoresists that have the potential to enable improvements in line edge(More)
—We demonstrate for the first time improvement of radio-frequency (RF) gain of SiC MESFETs by using source-connected field plates (FPs). MESFETs fabricated with this approach show a new record maximum stable gain exceeding 15.7 dB at 3.1 GHz. This is 2.7 dB higher than the baseline devices without FP. RF power output greater than 4W/mm was also achieved(More)
Approved for public release; distribution is unlimited. Abstract: This report describes a study to quantify the phytoextraction and phytostabilization capacities of TNT and RDX from spiked soil in selected herbaceous species, while paying attention to storage and quality of breakdown products in vegetative plant parts. Ten plant species were included in the(More)
