An understanding of convective weather impacts on en route airspace capacity is a first step toward development of predictive tools to support both tactical and strategic routing decisions in storm-impacted airspace. This study presents a model for traffic reductions in en route sectors that result from convective weather impacts. A model to predict the impact of convective weather on en route ...

Tissues with the highest rates of proliferation typically exhibit the highest frequencies of apoptosis, but the mechanisms that coordinate these processes are largely unknown. The homeodomain protein Gax is down-regulated when quiescent cells are stimulated to proliferate, and constitutive Gax expression inhibits cell proliferation in a p21(WAF/CIP)-dependent manner. To understand how mitogen-i...

Hepatocellular carcinoma is one of the most common cancers worldwide. During tumorigenesis, tumor suppressor and cancer-related genes are commonly silenced by aberrant DNA methylation in their promoter regions. Zebularine (1-(β-(D)-ribofuranosyl)-1,2-dihydropyrimidin-2-one) acts as an inhibitor of DNA methylation and exhibits chemical stability and minimal cytotoxicity both in vitro and in vivo...

Metabolic profiling of plasma nonesterified fatty acids discovered that palmitic acid (PA), a natural peroxisome proliferator-activated receptor γ (PPARγ) ligand, is a reliable type 2 diabetes biomarker. We investigated whether and how PA diabetic (d-PA) concentrations affected endothelial progenitor cell (EPC) and bone marrow-derived hematopoietic cell (BM-HC) biology. PA physiologic (n-PA) an...

Single and joint effects of hydrocarbons and a shoreline cleaning agent (SCA) were studied by measuring the inhibition of the larval growth of sea urchin. Different dosage methods of hydrophobic compounds were compared. The results obtained in the evaluation of CytoSol toxicity revealed that the method of variable dilution of water accommodated fraction (WAF) led to the more conservative toxico...

A new polyacetylenic compound, araliadiol, was isolated from the leaves of Aralia cordata Thunb. (Araliaceae). The structure of araliadiol was determined to be 3( S),8( R)-pentadeca-1,9( Z)-diene-4,6-diyne-3,8-diol by MS, NMR, IR, and UV spectroscopic analysis as well as Mosher ester reaction. Araliadiol displayed a significant inhibitory effect on the growth of a human breast adenocarcinoma ce...

Slow Feature Analysis (SFA) for vector-valued functions of several variables and apply it to the problem of blind source separation, in particular to image separation. It is generally necessary to use multivariate SFA instead of univariate SFA for separating multi-dimensional signals. For the linear case, an exact mathematical analysis is given, which shows in particular that the sources are pe...

Seed characteristics and in vitro culture of C. tamala embryos were studied. Embryos desiccated below 50% (fresh weight) exhibited poor morphogenetic response in vitro and confirmed the recalcitrant nature of seeds. The immature embryos of various developmental ages (4-16 week after flowering, WAF) were cultured on different strengths of MS medium. Morphogenesis responses were recorded after 10...
