The decomposition of Feynman integrals into a basis of independent master integrals is an essential ingredient of high-precision theoretical predictions, that often represents a major bottleneck when processes with a high number of loops and legs are involved. In this thesis we present a new algorithm for the decomposition of Feynman integrals into master integrals with the formalism of intersection theory. Intersection theory is a novel approach that allows to decompose Feynman integrals into master integrals via projections, based on a scalar product between Feynman integrals called intersection number. We propose a new purely rational algorithm for the calculation of intersection numbers of differential $n-$forms that avoids the presence of algebraic extensions. We show how expansions around non-rational poles, which are a bottleneck of existing algorithms for intersection numbers, can be avoided by performing an expansion in series around a rational polynomial irreducible over $\mathbb{Q}$, that we refer to as $p(z)-$adic expansion. The algorithm we developed has been implemented and tested on several diagrams, both at one and two loops.

Purpose: The purpose of our study was to compare signal characteristics and image qualities of MR imaging at 3.0 T and 1.5 T in patients with diffuse parenchymal liver disease. Materials and methods: 25 consecutive patients with diffuse parenchymal liver disease underwent abdominal MR imaging at both 3.0 T and 1.5 T within a 6-month interval. A retrospective study was conducted to obtain quantitative and qualitative data from both 3.0 T and 1.5 T MRI. Quantitative image analysis was performed by measuring the signal-to-noise ratios (SNRs) and the contrast-to-noise ratios (CNRs) by the Students t-test. Qualitative image analysis was assessed by grading each sequence on a 3- and 4-point scale, regarding the presence of artifacts and image quality, respectively. Statistical analysis consisted of the Wilcoxon signed-rank test. Results: the mean SNRs and CNRs of the liver parenchyma and the portal vein were significantly higher at 3.0 T than at 1.5 T on portal and equilibrium phases of volumetric interpolated breath-hold examination (VIBE) images (P < 0.05). The mean SNRs were significantly higher at 3.0 T than at 1.5 T on T1-weighted spoiled gradient echo (SGE) images (P < 0.05). However, there were no significantly differences on T2-weighted short-inversion-time inversion recovery (STIR) images. Overall image qualities of the 1.5 T noncontrast T1- and T2-weighted sequences were significantly better than 3.0 T (P < 0.01). In contrast, overall image quality of the 3.0 T post-gadolinium VIBE sequence was significantly better than 1.5 T (P< 0.01). Conclusions: MR imaging of post-gadolinium VIBE sequence at 3.0 T has quantitative and qualitative advantages of evaluating for diffuse parenchymal liver disease. (C) 2008 Elsevier Ireland Ltd.

Henry Haight Collier, was born in Howard, Steuben County, N. Y., November 28, 1818. His father, Richard Collier, was from Green County, in the same State. His grandfather, Isaac Collier, and his great-grandfather were originally from England. His mother, Mary Haight, was of Dutch origin. In 1835, Henry went to St. Catharines, where his elder brother, Richard Collier, resided. He spent two years at Grantham Academy, and then returned to Steuben County, to read law in Bath, with Edward Howell, and subsequently with Hammond and Campbell. Mr. Collier never opened a law office. He studied law for two years and in 1839 he went to Texas where he was connected with the State and Treasury Departments. In 1845 Mr. Collier returned to St. Catharines and opened a general store called St. Catharines Agricultural Works with his brother. The store remained open until May, 1877. He added the manufacturing of lumber in 1850, and manufacturing of agricultural implements in 1869. He built one of the first saw mills on the canal, on Lock No. 5, in St. Catharines. In July, 1877, he was appointed Collector of Customs. He became a Village Councilor for St. Paul’s Ward in 1859, and held that office from fifteen to twenty years. He was Deputy Reeve and member of the County Council for two terms. He was the Mayor of St. Catharines in 1872 and 1873. He was also Chairman of the Board of Water Commissioners of the city, during the time that the works were being built. He was a Justice of the Peace for twenty years or more. Mr. Collier was affiliated with the Reform Party and he was a Knight Templar in the Masonic fraternity and an Odd Fellow. He was also active in the Methodist Church. On June 1, 1858, he married Cornelia, daughter of Moses Cook, of "Westchester Place," St. Catharines, and had a daughter and son. Mary J. (married name: Mrs. Frank Camp) was a graduate of the Female Seminary at Hamilton, and Henry Herbert was a student in the University of Toronto. Henry H. Collier died on July 15, 1895 and is buried in Victoria Lawn Cemetery, St. Catharines, Ontario. Sources: www.accessgeneology.com "Historical Profiles from Victoria Lawn Cemetery" by Paul E.
