Sigma Gamma Epsilon 2014 Service Awards And Projects, Paula Even

The Compass: Earth Science Journal of Sigma Gamma Epsilon

In 2012, the Sigma Gamma Epsilon Chapter Service Award was established. The Chapter Service Award is based upon a non-profit/non-chapter fund raising activity that benefits the department, institution, or community. Four chapters received the award in 2014. Information about their projects as well as other chapters’ service projects is listed as well as the criteria for this award.

Search For Pair Production Of Third-Generation Scalar Leptoquarks And Top Squarks In Proton–Proton Collisions At √S=8tev, Cms Collaboration, Cern, Switzerland, Samantha Hewamanage, Stephan Linn, Pete E. Markowitz, German Martinez, Jorge Luis Rodriguez

Department of Physics

A search for pair production of third-generation scalar leptoquarks and supersymmetric top quark partners, top squarks, in final states involving tau leptons and bottom quarks is presented. The search uses events from a data sample of proton–proton collisions corresponding to an integrated luminosity of 19.7fb−1, collected with the CMS detector at the LHC with √s=8TeV. The number of observed events is found to be in agreement with the expected standard model background. Third-generation scalar leptoquarks with masses below 740GeV are excluded at 95% confidence level, assuming a 100% branching fraction for the leptoquark decay to a tau lepton and a …

Viscous And Induced Current Heating In Plasma Focus Plasmoids, Ahmad Talaei, Eric Lerner

Ahmad Talaei

Recently, Abolhasani et al, proposed that the high ion energies observed in plasmoids formed in the plasma focus could be explained by viscous heating. We here elaborate this proposal, demonstrating that during plasmoid formation, ion motion along magnetic field lines can be rapidly converted, at least in part, to thermal energy through viscous diffusion. This effect is strongly enhanced by higher-z ions. We compare the theoretical predictions with the recent observation by Lerner et al, of trapped ion energies of 160 keV. In addition, we propose a second source of heating. The mildly relativistic electron beam emitted by the plasmoid, …

Exploring The Dimensions Of Nomophobia: Developing And Validating A Questionnaire Using Mixed Methods Research, Caglar Yildirim

Caglar Yildirim

Nomophobia is defined as the fear of being out of mobile phone contact and is considered a modern age phobia introduced to our lives as a byproduct of the interaction between people and mobile information and communication technologies, especially smartphones. This research study sought to contribute to the nomophobia research literature by identifying and describing the dimensions of nomophobia and developing a questionnaire to measure nomophobia. Consequently, this study adopted a two-phase, exploratory sequential mixed methods design. The first phase was a qualitative exploration of nomophobia through semi-structured interviews conducted with nine undergraduate students at a large Midwestern university in …

Reply To ‘Co2 Emissions From Crop Residue-Derived Biofuels’, Adam Liska, Haishun Yang, Matthew P. Pelton, Andrew E. Suyker

Adam Liska Papers

The soil organic carbon (SOC) model that we used was parameterized with data from arable land under normal farming conditions in North America, Europe, Africa and Asia, but the equation is insensitive to changes in tillage, soil texture and moisture. The model has reasonable accuracy, however, in predicting changes in SOC, residue remaining and CO₂ emissions from initial SOC, carbon inputs from residue, and daily temperature; the shoot-to-root ratio used in the geospatial simulation was 0.29 (that is, root carbon is 29% of total aboveground carbon), which did not underestimate carbon input to soil (Supplementary Figure 2 in Ref. …

Symplectic Mackey Theory, Francois Ziegler

Department of Mathematical Sciences Faculty Publications

Many years ago Kazhdan, Kostant and Sternberg defined the notion of inducing a hamiltonian action from a Lie subgroup. In this paper, we develop the attendant imprimitivity theorem and Mackey analysis in the full generality needed to deal with arbitrary closed normal subgroups.

At its best, a university is a collection of individuals ‐‐ students and faculty ‐‐ focused on learning and discovering new knowledge. For this goal to be realized, a critical element is having faculty members deeply engaged in such discovery within their disciplines. Scholarship, in the form of journal articles, book chapters, monographs and similar endeavors, creative activity which can take an even wider range of forms, and funded research which explores the boundaries of disciplines all contribute to such engagement. Through such participation, faculty members stay at the growing edges of their fields, and in so doing, they enrich …

A Generator-Produced Gallium-68 Radiopharmaceutical For Pet Imaging Of Myocardial Perfusion, Nigam Rath, Vijay Sharma, Jothilingam Sivapackiam, Scott Harpstrite, Julie Prior, Hannah Gu, David Piwnica-Worms

Chemistry & Biochemistry Faculty Works

Lipophilic cationic technetium-99m-complexes are widely used for myocardial perfusion imaging (MPI). However, inherent uncertainties in the supply chain of molybdenum-99, the parent isotope required for manufacturing 99Mo/99mTc generators, intensifies the need for discovery of novel MPI agents incorporating alternative radionuclides. Recently, germanium/gallium (Ge/Ga) generators capable of producing high quality 68Ga, an isotope with excellent emission characteristics for clinical PET imaging, have emerged. Herein, we report a novel 68Ga-complex identified through mechanism-based cell screening that holds promise as a generator-produced radiopharmaceutical for PET MPI.
