Clay Carter, associate professor, Department of Biology, and Wayne Xu, University of Minnesota Supercomputing Institute, have published "Parallel multiplicity and error discovery rate (EDR) in microarray experiments" in the journal BMC Bioinformatics.

Tim Craig, associate professor, Department of Biology, recently had a paper published entitled, "The resource regulation hypothesis and positive feedback loops in plant-herbivore interactions." The paper appeared in Population Ecology, vol. 52, pages 461-473.

Douglas Dunham, professor, Department of Computer Science, attended five conferences in June, July, and August, giving talks at each. The first paper, "Creating Families of Repeating Patterns," was a plenary presentation at the Sixth Mathematics & Design International Conference, Buenos Aires, Argentina, June 7-11. The paper will appear in the conference proceedings. The second paper, "Creating Repeating Patterns with Color Symmetry," was presented at the International Society of Art, Mathematics, and Architecture (ISAMA) Conference 2010, DePaul University, Chicago, IL, June 21-25. The paper appears in the conference proceedings, the summer issue of Hyperseeing. Three color prints were also displayed at the Art Exhibit of ISAMA 2010. The third paper, "M.C. Escher's Use of the Poincave, Models of Hyperbolic Geometry" was presented at the first European Society for Mathematics and Art Conference (ESMA), Institut Henri Poincare, Paris, France, July 19-22. The fourth paper, "Hyperbolic Vasarely Patterns", was presented at the Bridges 2010 Conference, Pvecs, Hungary, July 24-28, and appears in the conference proceedings. Four color prints were also displayed at the Art Exhibit. The fifth paper, "A Family of `Three Element' M.C. Escher Patterns," was presented at the 14th International Conference on Geometry and Graphics, Kyoto University, Kyoto, Japan, Aug. 5-9, and appears in the CD proceedings.

Dalibor Froncek, professor, Department of Mathematics and Statistics, was an invited speaker in the special session on Graph Labelings at the Satellite Conference of the International Congress of Mathematicians “International Conference on Recent Trends in Graph Theory and Combinatorics” in Cochin, India. He presented a lecture “Incomplete round-robin tournaments and distance magic labelings.”

Robert Hecky, professor, Department of Biology, Norine Dobiesz, Large Lakes Observatory, Richard Axler and George Host, NRRI, and Cynthia Hagley, Minnesota Sea Grant, held a workshop in Jinja, Uganda from Sept. 15-17 to discuss fisheries data management and decision support tools. The workshop was held in response to a request by the Lake Victoria Fisheries Organization for advice and assistance in managing the burgeoning amount of data and information from Africa’s largest lake. In attendance were 30 fisheries managers and IT personnel from Uganda, Kenya, and Tanzania. Participants identified key issues facing Lake Victoria fisheries and how integrated data and advanced models can help address these concerns. This workshop and a follow-up meeting are funded by an Office of International Programs Seed Grant.

John Hiller, professor, Department of Physics, and Research Fellow Sophia Chabysheva recently published "On the nonperturbative solution of Pauli-Villars-regulated light-front QED: A comparison of the sector-dependent and standard parameterizations" in volume 325 of Annals of Physics.

Zhuangyi Liu, professor, Department of Mathematics and Statistics, attended the IX Workshop on Partial Differential Equations at Rio de Janeiro, Brazil from Aug. 24-27. He was an invited speaker and a member of Scientific Committee of the conference. He gave a talk on "Stability of a Beam-Spring System with Local Damping" which is a joint work with Caihong Zhang, a Ph.D. student from Ocean University of China who was supervised by professor Liu during her one year visit to UMD.

In August 2010, Daniel Martin, assistant professor, Department of Sociology and Anthropology, presented the paper, "Between Protesters and Police: The Role of Peace Team Members" at the American Sociological Association conference in Atlanta. The paper was co-authored with John Hamlin, assistant professor, Department of Sociology and Anthropology, and supported with funding from the Vice Chancellor's Academic Administration grant. The paper is the fourth research piece supported through VCAA funding and produced by the State Suppression of Dissent Project.

James Miller, associate professor, Department of Geological Sciences, was awarded a $35,000 grant from the MN Department of Natural Resouces to collaborate on a study of sulfate release from mining in the St. Louis River watershed. The funding will largely go toward support for Stephanie Theriault, an MS candidate in the Geology Department. Stephanie will be studying the sulfur isotope composition of sulfide in the Biwabik iron formation, a possible source of sulfate in the watershed.

Debao Zhou, assistant professor, Department of Mechanical and Industrial Engineering advised Jonas Swedberg, senior student in Department of MIE, who won third place in the 2010 ASME Student Mechanism & Robot Design Competition in Montreal, Quebec, Canada on Aug. 15-18. Swedberg presented a “Path Finding Track Vehicle."

Zhou, Peter Walls, Gordon Kuhnley, Alex Houck, Aaron Stotko, and Richard Lindeke published "Development of a Flexible Contact Sensor Array for Contact Force Identification during Colonoscopy" in Proceedings of the 12th Mechatronics Forum Biennial International Conference in Zurich, Switzerland from June 28-30. Zhou and Kevin Jax also had the paper "Design a Pressure Sensor Array with Reduced Number of Wires" in Proceedings of the 2010 IEEE International Conference on Information and Automation (ICIA 2010), pp 900-905, Harbin, Heilongjiang, China, June 20-23. Zhou was invited as conference session chair to "Sensors I," and "Sensors II" at the 2010 IEEE International Conference on Information and Automation, Harbin, Heilongjiang, China from June 20-23. He also presented his findings from “Design of a Pressure Sensor Array with Reduced Number of Wires" at the conference.
