    Nation and/or Homeland: Identity in 19th-Century Music and Literature between Central and Mediterranean Europe

    Get PDF
    The aim of this book is to focus on the development of national awareness elaborated around a series of different case studies, in which the terms nation, homeland and people have been applied. This Romantic lexicon identifies similar but various conceptions of the national idea in some countries dominated by Italian, German and Slavic cultures, and in some groups or minorities such as the Jews and the Vlachs in Central and Mediterranean Europe. In order to clarify the cultural framework, the authors explore the construction of identity through folk tunes, poetry inspired by popular culture, and opera in which the national myths or heroes appear. In the self-making tradition, the national traits are sustained by the process of embodiment of any regional utterance, and also by disregarding the \u201cother\u201d, in particular the minorities. The symbols of the nation, as an achievement of the power that flourishes from the sense of belonging, are defined \u201cper differentiam\u201d. Theoretical perspectives are shaped by the new approaches to this topic, taking into consideration the artistic issues as socio-historical events and subsequently evaluating them in their aesthetic quality

    Experimental Study of the Shortest Reset Word of Random Automata

    In this paper we describe an approach to finding the shortest reset word of a finite synchronizing automaton by using a SAT solver. We use this approach to perform an experimental study of the length of the shortest reset word of a finite synchronizing automaton. The largest automata we considered had 100 states. The results of the experiments allow us to formulate a hypothesis that the length of the shortest reset word of a random finite automaton with nn states and 2 input letters with high probability is sublinear with respect to nn and can be estimated as $1.95 n^{0.55}.

    Event-by-event fluctuations of average transverse momentum in central Pb+Pb collisions at 158 GeV per nucleon

    Get PDF
    We present first data on event-by-event fluctuations in the average transverse momentum of charged particles produced in Pb+Pb collisions at the CERN SPS. This measurement provides previously unavailable information allowing sensitive tests of microscopic and thermodynamic collision models and to search for fluctuations expected to occur in the vicinity of the predicted QCD phase transition. We find that the observed variance of the event-by-event average transverse momentum is consistent with independent particle production modified by the known two-particle correlations due to quantum statistics and final state interactions and folded with the resolution of the NA49 apparatus. For two specific models of non-statistical fluctuations in transverse momentum limits are derived in terms of fluctuation amplitude. We show that a significant part of the parameter space for a model of isospin fluctuations predicted as a consequence of chiral symmetry restoration in a non-equilibrium scenario is excluded by our measurement.Comment: 6 pages, 2 figures, submitted to Phys.

    Flavivirus Cell Entry and Membrane Fusion

    Get PDF
    Flaviviruses, such as dengue virus and West Nile virus, are enveloped viruses that infect cells through receptor-mediated endocytosis and fusion from within acidic endosomes. The cell entry process of flaviviruses is mediated by the viral E glycoprotein. This short review will address recent advances in the understanding of flavivirus cell entry with specific emphasis on the recent study of Zaitseva and coworkers, indicating that anionic lipids might play a crucial role in the fusion process of dengue virus [1]

    Two-proton correlations from 158 AGeV Pb+Pb central collisions

    Get PDF
    The two-proton correlation function at midrapidity from Pb+Pb central collisions at 158 AGeV has been measured by the NA49 experiment. The results are compared to model predictions from static thermal Gaussian proton source distributions and transport models RQMD and VENUS. An effective proton source size is determined by minimizing CHI-square/ndf between the correlation functions of the data and those calculated for the Gaussian sources, yielding 3.85 +-0.15(stat.) +0.60-0.25(syst.) fm. Both the RQMD and the VENUS model are consistent with the data within the error in the correlation peak region.Comment: RevTeX style, 6 pages, 4 figures, 1 table. More discussion are added about the structure on the tail of the correlation function. The systematic error is revised. To appear in Phys. Lett.

    Baryon Stopping and Charged Particle Distributions in Central Pb+Pb Collisions at 158 GeV per Nucleon

    Get PDF
    Net proton and negative hadron spectra for central \PbPb collisions at 158 GeV per nucleon at the CERN SPS were measured and compared to spectra from lighter systems. Net baryon distributions were derived from those of net protons, utilizing model calculations of isospin contributions as well as data and model calculations of strange baryon distributions. Stopping (rapidity shift with respect to the beam) and mean transverse momentum \meanpt of net baryons increase with system size. The rapidity density of negative hadrons scales with the number of participant nucleons for nuclear collisions, whereas their \meanpt is independent of system size. The \meanpt dependence upon particle mass and system size is consistent with larger transverse flow velocity at midrapidity for \PbPb compared to \SS central collisions.Comment: This version accepted for publication in PRL. 4 pages, 3 figures.
