    Red Rural, Blue Rural; Rural Does Not Always Equal Republican

    Get PDF
    In this fact sheet, authors Dante Scala and Kenneth Johnson examine voting data for nearly 9,000 rural residents to identify how voting patterns differ across rural areas comparing farm and recreational counties to those elsewhere in rural America. They also examine voting data from the 2008 and 2012 Presidential elections for each rural county. Scala and Johnson report that rural America is not the undifferentiated Republican bastion depicted by commentators. While Republican presidential candidates do best in rural counties dominated by farming, Democratic presidential candidates do well in rural counties dominated by recreation. In “battleground” states, these rural differences may impact tightly contested elections

    Geometric phase accumulation-based effects in the quantum dynamics of an anisotropically trapped ion

    Full text link
    New physical effects in the dynamics of an ion confined in an anisotropic two-dimensional Paul trap are reported. The link between the occurrence of such manifestations and the accumulation of geometric phase stemming from the intrinsic or controlled lack of symmetry in the trap is brought to light. The possibility of observing in laboratory these anisotropy-based phenomena is briefly discussed.Comment: 10 pages. Acta Physica Hungarica B 200

    Zeno Dynamics and High-Temperature Master Equations Beyond Secular Approximation

    Get PDF
    Complete positivity of a class of maps generated by master equations derived beyond the secular approximation is discussed. The connection between such class of evolutions and physical properties of the system is analyzed in depth. It is also shown that under suitable hypotheses a Zeno dynamics can be induced because of the high temperature of the bath.Comment: 9 pages, 2 figure

    Beyond Urban Versus Rural:

    In this brief, authors Dante Scala and Kenneth Johnson examine voting patterns over the last five presidential elections. They report that although rural voters and urban voters are often portrayed as polar opposites, their differences are best understood as a continuum, not a dichotomy. From the largest urban cores to the most remote rural counties, they found significant variations in voting. Hillary Clinton nearly matched Barack Obama’s 2012 performance in most urban areas. Clinton’s defeat was due, in part, to her failure to match the performance of recent Democratic Presidential nominees in less populated areas. Though many commentators argued that the faster population growth and growing diversity on the urban side of the rural–urban continuum would give Democrats a significant advantage in 2016, the election demonstrated that what happens at the rural end of the continuum remains important

    GHZGHZ state generation of three Josephson qubits in presence of bosonic baths

    Full text link
    We analyze an entangling protocol to generate tripartite Greenberger-Horne-Zeilinger states in a system consisting of three superconducting qubits with pairwise coupling. The dynamics of the open quantum system is investigated by taking into account the interaction of each qubit with an independent bosonic bath with an ohmic spectral structure. To this end a microscopic master equation is constructed and exactly solved. We find that the protocol here discussed is stable against decoherence and dissipation due to the presence of the external baths.Comment: 16 pages and 4 figure

    Many new voters make the Granite State one to watch in November

    A third of potential voters in New Hampshire during the fall of 2008 have become eligible to vote in the state. Further, these potential new voters are more likely to identify with the Democratic Party and less likely to identify as Republicans than are established New Hampshire voters, contributing to the state\u27s purple status
