An Improved Algorithm for Generating Database Transactions from Relational Algebra Specifications
Alloy is a lightweight modeling formalism based on relational algebra. In
prior work with Fisler, Giannakopoulos, Krishnamurthi, and Yoo, we have
presented a tool, Alchemy, that compiles Alloy specifications into
implementations that execute against persistent databases. The foundation of
Alchemy is an algorithm for rewriting relational algebra formulas into code for
database transactions. In this paper we report on recent progress in improving
the robustness and efficiency of this transformation
Keeping the Internet Neutral?: Tim Wu and Christopher Yoo Debate
Network neutrality has emerged as one of the highest profile issues in telecommunications and Internet policy last year. Not only did it play a pivotal role in both houses of Congress during debates over proposed communications reform legislation; it also emerged as a key consideration during the Federal Communications Commission consideration of the recent SBC-AT&T, Verizon-MCI, and AT&T-BellSouth mergers. In the following exchange, Professors Tim Wu and Christopher Yoo engage in a lively debate over the merits of network neutrality that reviews the leading arguments on both sides of the issue

Assessing the discordance rate between local and central HER2 testing in women with locally determined HER2-negative breast cancer.
BackgroundThe importance of human epidermal growth factor receptor 2 (HER2) as a prognostic and predictive marker in invasive breast cancer is well established. Accurate assessment of HER2 status is essential to determine optimal treatment options.MethodsBreast cancer tumor tissue samples from the VIRGO observational cohort tissue substudy that were locally HER2-negative were retested centrally with both US Food and Drug Administration (FDA)-approved immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) assays, using FDA-approved assay cutoffs; results were compared.ResultsOf the 552 unique patient samples centrally retested with local HER2-negative results recorded, tumor samples from 22 (4.0%) patients were determined to be HER2-positive (95% confidence interval [CI] = 2.5%-5.7%). Of these, 18 had been tested locally by only one testing methodology; 15 of 18 were HER2-positive after the central retesting, based on the testing methodology not performed locally. Compared with the 530 patients with centrally confirmed HER2-negative tumors, the 22 patients with centrally determined HER2-positive tumors were younger (median age 56.5 versus 60.0 years) and more likely to have ER/PR-negative tumors (27.3% versus 22.3%). These patients also had shorter median progression-free survival (6.4 months [95% CI = 3.8-15.9 months] versus 9.1 months [95% CI = 8.3-10.3 months]) and overall survival (25.9 months [95% CI = 13.8-not estimable] versus 27.9 months [95% CI = 25.0-32.9 months]).ConclusionsThis study highlights the limitations of employing just one HER2 testing methodology in current clinical practice. It identifies a cohort of patients who did not receive potentially efficacious therapy because their tumor HER2-positivity was not determined by the test initially used. Because of inherent limitations in testing methodologies, it is inadvisable to rely on a single test to rule out potential benefit from HER2-targeted therapy
Oral History Interview: Sanghong Yoo
This interview is one of series conducted concerning the Oral History of Appalachia. Sanghong Yoo was an international student from South Korea, enrolled in ESL and the Graduate College at Marshall University in 1996. At the time of the interview, he was a research faculty member at Marshall. He discusses: his family, his educational background; why he came to Marshall; other international students at Marshall; life for international students at Marshall; what he did on September 11th, 2001; how life has changed for international students after September 11th; why he stayed at Marshall after graduation; returning to South Korea to finish graduate school; returning to Marshall; his views on international students; and other topics.https://mds.marshall.edu/oral_history/1596/thumbnail.jp
Higher congruences between newforms and Eisenstein series of squarefree level
Let be prime. For elliptic modular forms of weight 2 and level
where is squarefree, we bound the depth of Eisenstein
congruences modulo (from below) by a generalized Bernoulli number with
correction factors and show how this depth detects the local non-principality
of the Eisenstein ideal. We then use admissibility results of Ribet and Yoo to
give an infinite class of examples where the Eisenstein ideal is not locally
principal. Lastly, we illustrate these results with explicit computations and
give an interesting commutative algebra application related to Hilbert--Samuel
multiplicities.Comment: 19 pages. Minor revisions. Accepted for publication in The Journal de

Introduction: Reflections on nancy abelmann's legacy
Nancy Abelmann passed away on January 6, 2016, at the age of fifty-six. She received her PhD from the University of California, Berkeley in 1990, after completing her dissertation under Nelson Graburn. That same year, she was hired by the University of Illinois, Urbana-Champaign, where she worked for two and a half decades. She was a beloved teacher, mentor, and colleague to many, and she was a key figure in multiple departments and centers. At the time of her death, she held the Harold E. Preble Professorship in Anthropology, Asian American Studies, East Asian Languages and Cultures, and Women and Gender Studies and was also Associate Vice Chancellor for Research
