âHeirs of Freedomâ or âSlaves to Englandâ? Protestant Society and Unionist Hegemony in Nineteenth-Century Ulster
Drawing partly on Ulster Protestant emigrant correspondence and partly on new research in Irish religious demography, this article challengesconventional (ârevisionistâ) interpretations of the evolution of Ulster Protestant, especially Presbyterian, society and political culture, from Irish nationalism to British loyalism, in the half-century after the Irish Rebellion of 1798. It posits, for example, that Presbyterian nationalism and republicanism were not so much ânaturallyâ diluted in Ulster by industrialism, Orangeism, and evangelicalism as they were exported overseas, by mass migration to the USA, 1800-1850, and suppressed in Ulster by hegemonic and reactionary (and largely Anglican) systems and pressures, which many Presbyterians consciously rejected and, they believed, âescapedâ through emigration to an idealized American republic
Identification of genes associated with complex traits by testing the genetic dissimilarity between individuals
Abstract
Using the exome sequencing data from 697 unrelated individuals and their simulated disease phenotypes from Genetic Analysis Workshop 17, we develop and apply a gene-based method to identify the relationship between a gene with multiple rare genetic variants and a phenotype. The method is based on the Mantel test, which assesses the correlation between two distance matrices using a permutation procedure. Using up to 100,000 permutations to estimate the statistical significance in 200 replicate data sets, we found that the method had 5.1% type I error at an α level of 0.05 and had various power to detect genes with simulated genetic associations. FLT1 and KDR had the most significant correlations with Q1 and were replicated 170 and 24 times, respectively, in 200 simulated data sets using a Bonferroni corrected p-value of 0.05 as a threshold. These results suggest that the distance correlation method can be used to identify genotype-phenotype association when multiple rare genetic variants in a gene are involved.http://deepblue.lib.umich.edu/bitstream/2027.42/112957/1/12919_2011_Article_1171.pd

Automated extraction of chemical structure information from digital raster images
Background: To search for chemical structures in research articles, diagrams or text representing molecules need to be translated to a standard chemical file format compatible with cheminformatic search engines. Nevertheless, chemical information contained in research articles is often referenced as analog diagrams of chemical structures embedded in digital raster images. To automate analog-to-digital conversion of chemical structure diagrams in scientific research articles, several software systems have been developed. But their algorithmic performance and utility in cheminformatic research have not been investigated. Results: This paper aims to provide critical reviews for these systems and also report our recent development of ChemReader -- a fully automated tool for extracting chemical structure diagrams in research articles and converting them into standard, searchable chemical file formats. Basic algorithms for recognizing lines and letters representing bonds and atoms in chemical structure diagrams can be independently run in sequence from a graphical user interface-and the algorithm parameters can be readily changed-to facilitate additional development specifically tailored to a chemical database annotation scheme. Compared with existing software programs such as OSRA, Kekule, and CLiDE, our results indicate that ChemReader outperforms other software systems on several sets of sample images from diverse sources in terms of the rate of correct outputs and the accuracy on extracting molecular substructure patterns. Conclusion: The availability of ChemReader as a cheminformatic tool for extracting chemical structure information from digital raster images allows research and development groups to enrich their chemical structure databases by annotating the entries with published research articles. Based on its stable performance and high accuracy, ChemReader may be sufficiently accurate for annotating the chemical database with links to scientific research articles.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90875/1/Saitou8.pd
