In this study, the Community Multiscale Air Quality (CMAQ) modeling system is used to simulate the ozone (O3) episodes during the Program of Regional Integrated Experiments of Air Quality over the Pearl River Delta, China, in October 2004 (PRIDE-PRD2004). The simulation suggests that O3 pollution is a regional phenomenon in the Pearl River Delta (PRD). Elevated O3 levels often occurred in the s...

Experiments were conducted to evaluate the impact of groundwater chemistry and travel distance on the transport and fate behavior of PRD-1, a bacteriophage employed as a surrogate tracer for pathogenic enteric viruses. The experiments were conducted in the unconfined aquifer at the United States Geological Survey Cape Cod Toxic-Substances Hydrology Research Site in Falmouth, Massachusetts. The ...

OBJECTIVE To examine the safety and efficacy of methotrexate (MTX) plus low-dose prednisolone for induction of remission in non life- or organ-threatening courses and for remission maintenance in Churg-Strauss syndrome (CSS). METHODS In an open-label study 11 patients were treated with MTXfor induction of remission at initial diagnosis and relapse. Twenty-five patients received MTX for mainte...

Vitamin D, upon its discovery one century ago, was classified as a vitamin. This classification still greatly affects our perception about its biological role. 1,25(OH)2D (now known as the D hormone) is a pleiotropic steroid hormone that has multiple biologic effects. It is integral to the regulation of calcium homeostasis and bone turnover as well as having anti-proliferative, pro-differentiat...

A new circadian clock mutant has been isolated in Neurospora crassa. This new mutation, called period6 (pd -6 ) , has two features novel to known clock mutations. First, the mutation is temperature sensitive. At restrictive temperatures (above 21") the mutation shortens circadian period length from a wild-type value of 21.5 hr to 18 hr. At permissive temperatures (below 21") the mutant has a 20...

Increasing cost and scarcity of maize has stimulated the use of alternative feed sources (AFS) in the diets of cattle. In this study, we investigated the effects of partial or total replacement of maize on nutrient digestibility, growth performance, blood metabolites, and economics in Limousin crossbred feedlot cattle. Forty-five Limousin×Luxi crossbred bulls were randomly assigned to the three...

Title of dissertation: REUSE DISTANCE ANALYSIS FOR LARGE-SCALE CHIP MULTIPROCESSORS Meng-Ju Wu, Doctor of Philosophy, 2012 Dissertation directed by: Professor Donald Yeung Department of Electrical and Computer Engineering Multicore Reuse Distance (RD) analysis is a powerful tool that can potentially provide a parallel program’s detailed memory behavior. Concurrent Reuse Distance (CRD) and Priva...

Seven members of the Mix family of paired-type homeoproteins regulate mesoderm/endoderm differentiation in amphibians. In mammals, the MIXL1 (Mix. 1 homeobox [Xenopus laevis]-like gene 1) gene is the sole representative of this family. Unlike the amphibian Mix genes that encode an open reading frame of >300 amino acids, mammalian MIXL1 encodes a smaller protein (approximately 230aa). However, m...
