Design studies for a long base-line neutrino beam
Strong interest has recently been shown in very long base-line neutrino beams, directed at existing or planned massive detector facilities, in order to extend the search for neutrino oscillations. Among such possibilities are beams from CERN pointing towards the Gran Sasso Underground Laboratory in the Ionian Sea off the west coast of the Peloponnese. In order to establish the basic parameters, a number of possible configurations for such beams have been studies covering a range of neutrino energy bands, estimates of the neutrino fluxes, event rates and backgrounds at typical detectors are reported. Considerations have been gioven to the optimum lenght and radius of the decay tunnels. It is shown that with one year of operation, a neutrino oscillation search down to limits of sin2 Ø = 0.01 and m2 = 0.001eV2 could be made with currently proposed detectors
Future large-scale water-Cherenkov detector
MEMPHYS (MEgaton Mass PHYSics) is a proposed large-scale water-Cherenkov
experiment to be performed deep underground. It is dedicated to nucleon decay
searches and the detection of neutrinos from supernovae, solar, and atmospheric
neutrinos, as well as neutrinos from a future beam to measure the CP violating
phase in the leptonic sector and the mass hierarchy. This paper provides an
overview of the latest studies on the expected performance of MEMPHYS in view
of detailed estimates of its physics reach, mainly concerning neutrino beams
Study of the performance of a large scale water-Cherenkov detector (MEMPHYS)
MEMPHYS (MEgaton Mass PHYSics) is a proposed large-scale water Cherenkov
experiment to be performed deep underground. It is dedicated to nucleon decay
searches, neutrinos from supernovae, solar and atmospheric neutrinos, as well
as neutrinos from a future Super-Beam or Beta-Beam to measure the CP violating
phase in the leptonic sector and the mass hierarchy. A full simulation of the
detector has been performed to evaluate its performance for beam physics. The
results are given in terms of "Migration Matrices" of reconstructed versus true
neutrino energy, taking into account all the experimental effects.Comment: Updated after JCAP's referee's comment
Intraday Markets for Power: Discretizing the Continuous Trading
A fundamental question regarding the design of electricity markets is whether adding auctions to the continuous intraday trading is improving the performance of the market. To approach this question, we assess the experience with the implementation of the 3 pm local auction for quarters in Germany at the European Power Exchange (EPEX SPOT) in December 2014 to assess the impact on trading volumes/liquidity, prices, as well as market depth. We discuss further opportunities and challenges that are linked with a potential implementation of an intraday auction

CNGS: Effects of possible alignment errors
Simulations of the CNGS neutrino beam from CERN to the Gran Sasso Laboratory (LNGS)assume that the proton beam and all secondary beam elements are perfectly aligned on an axis between the two laboratories. This study examines the effects on the neutrino flux at Gran Sasso of deviations from the axis of the primary proton beam and misalignment of secondary beam elements. It also examines how such deviation or misalignment can be detected at monitors placed along the secondary beam line at CERN and at Gran Sasso. Calculations are based on the CNGS neutrino beam, optimized for nu_mu ->nu_tau appearance experiments as described in the Addendum to the Conceptual Technical Design Report of CNGS. It is shown that the number of neutrino charged current events predicted at Gran Sasso is insensitive to all but the most extreme misalignments
Linking shyness to social anxiety in children through the Clark and Wells cognitive model
This is the author accepted manuscript. The final version is available from Ellinika Grammata via the link in this record.Past research has begun to show that cognitive biases partially mediate the relation between shyness and social anxiety. In addition, it has been showed that the Clark and Wells (1995) cognitive model generalizes to youth. This study investigated the mediating role of the model in the link between shyness and social anxiety. Participants were 306 preadolescents, who completed measures of shyness, social anxiety, and cognitive variables implicated by the model (anticipatory processing, post-event processing, and social attitudes). The results confirmed that shyness, social anxiety and maladaptive cognitive processes were intercorrelated. Further, in a multiple mediator model, social attitudes, but not anticipatory or post-event processing, partially mediated the relation between shyness and social anxiety. Implications for school prevention interventions are briefly discussed
Updated results of the Horn Study for the Nufact
An updated study of a magnetic horn as a possible option for the pion collection system at the Neutrino Factory is presented. The pion yield is similar to that obtained from the standard benchmark solenoid
Analytical model of asymmetrical Mixed-Mode Bending test of adhesively bonded GFRP joint
This paper presents new analytical model of asymmetric mixed-mode bending (MMB) specimen ofadhesively bonded pultruded GFRP joints. An easily applicable relationship for the calculation of the strainenergy release rate of the asymmetric MMB specimens is proposed based on the beam theory. The model iscapable to analyze stacking sequence as well as various crack propagation paths. In the paper the effect of thevarious fiber bridging length and different crack propagation paths is analyzed analytically and supported byexperimental results. The methodology and results presented in this paper could be utilized for the design ofboth joint geometry and lay-up of the laminates constituting the joint or for the prediction of the fracturebehavior of such structures
