Background: Microarray data sets provide relative expression levels for thousands of genes for a small number, in comparison, of different experimental conditions called assays. Data mining techniques are used to extract specific information of genes as they relate to the assays. The multivariate statistical technique of principal component analysis (PCA) has proven useful in providing effective data mining methods. This article extends the PCA approach of Rollins et al. to the development of ranking genes of microarray data sets that express most differently between two biologically different grouping of assays. This method is evaluated on real and simulated data and ...


Unleashing Biocatalysis/Chemical Catalysis Synergies For Efficient Biomass Conversion, Brent H. Shanks Jan 2007

Unleashing Biocatalysis/Chemical Catalysis Synergies For Efficient Biomass Conversion, Brent H. Shanks

Chemical and Biological Engineering Publications

The goal of incorporating renewable carbon into the fuel and chemical enterprise will most likely be successful when combined systems of biocatalysts and chemical catalysts are exploited. Significant efforts in the biocatalytic release of sugars from biomass are being pursued for subsequent use in fermentation. Two recent papers demonstrate an alternative approach to converting these sugars to a liquid fuel by using chemical catalysts.
