Opinion Dynamics: the Effect of the Number of Peers Met at Once
(2008)Journal of Artificial Societies and Social SimulationThe opinion dynamics model introduced by Deffuant and Weisbuch as well as the one by Hegselmann and Krause are rather similar. In both models individuals are assumed to have opinions about an issue, they meet and discuss, and they may adapt their opinions towards the other agents` opinions or may ignore each other if their positions are too different. Both models differ with respect to the number of peers they meet at once. Furthermore ...Journal Article -
Collider aspects of flavor physics at high Q
(2008)The European Physical Journal CThis chapter of the “Flavor in the era of LHC” workshop report discusses flavor-related issues in the production and decays of heavy states at the LHC at high momentum transfer Q, both from the experimental and the theoretical perspective. We review top quark physics, and discuss the flavor aspects of several extensions of the standard model, such as supersymmetry, little Higgs models or models with extra dimensions. This includes discovery ...Journal Article -
A precise measurement of the muon neutrino–nucleon inclusive charged current cross section off an isoscalar target in the energy range 2.5 < Eν < 40 GeV by NOMAD
(2008)Physics Letters BWe present a measurement of the muon neutrino-nucleon inclusive charged current cross section, off an isoscalar target, in the neutrino energy range 2.5 ≤ E ν ≤ 40 GeV. The significance of this measurement is its precision, ±4% in 2.5 ≤ E ν ≤ 10 GeV, and ±2.6% in 10 ≤ E ν ≤ 40 GeV regions, where significant uncertainties in previous experiments still exist, and its importance to the current and proposed long baseline neutrino oscillation ...Journal Article -
Local eigenvalue analysis of CMIP3 climate model errors
(2008)Tellus A: Dynamic Meteorology and OceanographyOf the two dozen or so global atmosphere—ocean general circulation models (AOGCMs), many share parameterizations, components or numerical schemes, and several are developed by the same institutions. Thus it is natural to suspect that some of the AOGCMs have correlated error patterns. Here we present a local eigenvalue analysis for the AOGCM errors based on statistically quantified correlation matrices for these errors. Our statistical ...Journal Article -
Waterborne outbreak of acute gastroenteritis in a costal area in Slovenia in June and July 2008
(2008)EurosurveillanceIn June and July 2008, an outbreak of acute gastroenteritis with a total of at least 408 cases occurred in the municipality of Piran, Slovenia. The town has 17,400 inhabitants and is located in touristic area on the Slovenian Adriatic coast. The first 20 cases were reported on 26 June to regional Institute of Public Health Koper (IPH Koper). Preliminary interviews indicated that the only common source of exposure was the local water ...Journal Article -
B , D and K decays
(2008)The European Physical Journal CThe present report documents the results of Working Group 2: B, D and K decays, of the workshop on Flavor in the Era of the LHC, held at CERN from November 2005 through March 2007. With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator facilities. While direct detection of new particles will be the main avenue to ...Journal Article -
Probing quantum gravity using photons from a flare of the active galactic nucleus Markarian 501 observed by the MAGIC telescope
(2008)Physics Letters BWe analyze the timing of photons observed by the MAGIC telescope during a flare of the active galactic nucleus Mkn 501 for a possible correlation with energy, as suggested by some models of quantum gravity (QG), which predict a vacuum refractive index ≃ 1 + (E / MQGn)n, n = 1, 2. Parametrizing the delay between γ-rays of different energies as Δ t = ± τl E or Δ t = ± τq E2, we find τl = (0.030 ± 0.012) s / GeV at the 2.5-σ level, and τq = ...Journal Article -
Flavor physics of leptons and dipole moments
(2008)The European Physical Journal CThis chapter of the report of the “Flavor in the era of the LHC” Workshop discusses the theoretical, phenomenological and experimental issues related to flavor phenomena in the charged lepton sector and in flavor conserving CP-violating processes. We review the current experimental limits and the main theoretical models for the flavor structure of fundamental particles. We analyze the phenomenological consequences of the available data, ...Journal Article -
Short-wave and long-wave surface radiation budgets in GCMs: a review based on the IPCC-AR4/CMIP3 models
(2008)Tellus A: Dynamic Meteorology and OceanographyHere I review the developments in the representation of radiation budgets in global climate models (GCMs) from a surface perspective, considering early models up to the latest model generation used in the IPCC fourth assessment report (AR4). As in previous model generations, considerable differences in the simulated global mean radiation budgets are also present in the IPCC-AR4 models, particularly in the atmosphere and at the surface. I ...Journal Article -
The inexorable spread of a newly arisen neo-Y chromosome
(2008)PLoS GeneticsA newly arisen Y-chromosome can become established in one part of a species range by genetic drift or through the effects of selection on sexually antagonistic alleles. However, it is difficult to explain why it should then spread throughout the species range after this initial episode. As it spreads into new populations, it will actually enter females. It would then be expected to perform poorly since it will have been shaped by the ...Journal Article
