226 DeTar, CarletonQCD equation of state with 2+1 flavors of improved staggered quarksWe report results for the interaction measure, pressure, and energy density for nonzero-temperature QCD with 2 + 1 flavors of improved staggered quarks. In our simulations, we use a Symanzik improved gauge action and the Asqtad O(a2) improved staggered quark action for lattices with temporal extent ...Staggered quarks; Quark-gluon plasma2007-05

228 Freire, Juliana; Silva, Claudio T.Querying and creating visualizations by analogyWhile there have been advances in visualization systems, particularly in multi-view visualizations and visual exploration, the process of building visualizations remains a major bottleneck in data exploration. We show that provenance metadata collected during the creation of pipelines can be reused ...Provenance; VisTrails; Pipelines; Query-by-example2007-11
229 Dawson, KyleRadio point sources toward galaxy clusters at 30 GHzExtra-galactic radio sources are a significant contaminant in cosmic microwave background and Sunyaev-Zel'dovich effect experiments.

230 Crowe, Benjamin D.Reasons for worship: a response to Bayne and NagasawaWorship is a topic that is rarely considered by philosophers of religion. In a recent paper, Tim Bayne and Yujin Nagasawa challenge this trend by offering an analysis of worship and by considering some difficulties attendant on the claim that worship is obligatory. I argue that their case for there...Tim Bayne; Yujin Nagasawa; Obligatory worship; Divine command2007-12
231 Harrison, Reid R.; Furse, Cynthia M.Recent advances in biomedical telemetryCommunication systems for implantable medical devices are rapidly advancing.

232 Furse, Cynthia M.Recovering handset diversity and MIMO capacity with polarization-agile antennasDesign guidance is provided for multiple-input-multiple- output (MIMO) antenna systems on handsets-a strong prospect for next generation wireless devices. Handheld wireless devices are likely to be rotated out of their optimal polarization, thereby experiencing significant power losses. An existin...Adaptive arrays; Diversity methods; Multiple-intput-multiple-output; MIMO; Handset diversity; Handheld devices; Polarization agile antenna2007-11
233 Furse, Cynthia M.Recovering handset MIMO capacity with polarization-agile antennasMultiple Input Multiple Output (MIMO) communication systems rely on significant variation between multiple signal paths to create independent channels for communication. Transceiver signal strength to or from a portable handset is subject to large variations due to the "essentially random orientatio...2007-06

235 Boehme, ChristophRoom temperature electrical detection of spin coherence in C60An experimental demonstration of electrical detection of coherent spin motion of weakly coupled, localized electron spins in thin fullerene C60 films at room temperature is presented. Pulsed electrically detected magnetic resonance experiments on vertical photocurrents through Al/C60/ZnO samples sh...Spin coherence2007-05
236 Lupton, John MarkRoom-temperature exciton storage in elongated semiconductor nanocrystalsThe excited state of colloidal nanoheterostructures consisting of a spherical CdSe nanocrystal with an epitaxially attached CdS rod can be perturbed effectively by electric fields. Field-induced fluorescence quenching coincides with a conversion of the excited state species from the bright exciton ...Exciton storage; Colloidal nanoheterostructures; CdSe nanocrystal2007-01
237 DeTar, CarletonScalar meson spectroscopy with lattice staggered fermionsWith sufficiently light up and down quarks the isovector (a0) and isosinglet (f0) scalar meson propagators are dominated at large distance by two-meson states. In the staggered-fermion formulation of lattice quantum chromodynamics, taste-symmetry breaking causes a proliferation of two-meson states t...Staggered fermions; Chiral theory2007-11

239 Lupton, John MarkSimultaneous Raman and fluorescence spectroscopy of single conjugated polymer chainsSimultaneous surface enhanced Raman scattering (SERS) and fluorescence is demonstrated from single conjugated polymer chains. As resonance enhancement of SERS depends on the spectral overlap of the polymer's absorption and the incident laser, resonance Raman and fluorescence effectively probe the ab...Surface enhanced Raman scattering; SERS; Resonance enhancement2007-03
240 Mishchenko, Eugene; Raikh, Mikhail E.Smearing of the two-dimensional Kohn anomaly in a nonquantizing magnetic field: implications for interaction effectsThermodynamic and transport characteristics of a clean two-dimensional interacting electron gas are shown to be sensitive to the weak perpendicular magnetic field even at temperatures much higher than the cyclotron energy, when the quantum oscillations are completely washed out. We demonstrate this ...Kohn anomaly; Tunnel density of states2007-07

244 Caserta, Michael; Lund, Dale A.Toward the development of an inventory of daily widowed life (IDWL): guided by the duel process model of coping with bereavementThe Dual Process Model of Coping with Bereavement (Stroebe & Schut, 1999) suggests that the most effective adaptation involves oscillaton between two coping processes: loss-orientation (LO) and restoration-orientation (RO). A 22-item Inventory of Daily Widowed Life (IDWL) was developed to measure t...Bereavement; Grief reaction; Widowhood; Psychological orientation; Adaptation, Psychological2007-07
245 Wu, Yong-ShiUniversal distribution of spectral-flow gaps in the Rashba model with disorderWe report a study of disordered electron systems with spin-orbit coupling on a cylinder using methods of random matrix ensembles.

247 Millgram, ElijahWho was Nietzsche's genealogist?Nietzsche's Genealogy of Morals is deservedly part of the ethical canon, but it is also enormously and insistently absent-minded. I'm going to first present, as a textual puzzle, a handful of forgetful moments in the first two essays of the Genealogy. To address the puzzle, I will take up a familiar...2007-07
248 Mishchenko, Eugene; Raikh, Mikhail E.Zero-bias tunneling anomaly in a clean 2D electron gas caused by smooth density variationsWe show that smooth variations, δn(r), of the local electron concentration in a clean 2D electron gas give rise to a zero-bias anomaly in the tunnel density of states, v(ω), even in the absence of scatterers, and thus, without the Friedel oscillations. The energy width, ω0, of the anomaly scale...Tunnel density of states; Disordered metals2007-11
