  • Type IIB on S 3 × S 3 through Q & P fluxes

    Danielsson, Ulf   Dibitetto, Giuseppe  

    We study a class of orientifold compactifications of type IIB supergravity with fluxes down to 4D in connection with truncations of half-maximal gauged supergravities yielding isotropic STU-models with minimal supersymmetry. In this context, we make use of a group-theoretical approach in order to derive flux-induced superpotentials for different IIB backgrounds. We first review the toroidal case yielding GKP-like superpotentials characterised by their no-scale behaviour. We then turn to S 3 × S 3 and S 3 × \( {\mathbb{T}}^3 \), which, surprisingly, give rise to effective descriptions of non-geometric Q- and P -fluxes through globally geometric non-toroidal compactifications. As a consequence, such constructions break the no-scale symmetry without invoking any non-perturbative effects.

  • Hexavalent (G, s)-transitive graphs

    Guo, Song-Tao   Hua, Xiao-Hui   Li, Yan-Tao  

    Let X be a finite simple undirected graph with a subgroup G of the full automorphism group Aut(X). Then X is said to be (G, s)-transitive for a positive integer s, if G is transitive on s-arcs but not on (s + 1)-arcs, and s-transitive if it is (Aut(X), s)-transitive. Let G (v) be a stabilizer of a vertex v a V (X) in G. Up to now, the structures of vertex stabilizers G (v) of cubic, tetravalent or pentavalent (G, s)-transitive graphs are known. Thus, in this paper, we give the structure of the vertex stabilizers G (v) of connected hexavalent (G, s)-transitive graphs.

  • The Way Forward for Simulation & Gaming (S&G)

    Clapper, Timothy C.  

    The fields of simulation and gaming are expanding into innovative and increasingly popular areas, including simulation in healthcare, recreational games for educational purposes, urban planning, military simulation and modeling, and more. This editorial serves as a farewell to a distinguished editor of Simulation & Gaming (S&G) and an introduction of the new editors who will maintain the highest standards for the journal and guide it to newer domains, while unveiling best-practices in underreported areas of the world.

  • ETGP: Top-K Geography-Text P/S Approach without Threshold

    Social media are more and more popular. Subsequently, geography-text data has caused wide attention. Different from the traditional publish/subscribe (P/S), geography-text data is published and subscribed in the form of dynamic data flow in the mobile network. The difference raises higher demands for facility. However, previous top-k geography-text P/S approaches want to set a set of thresholds. A user should take time to set a threshold for each subscription, which is not facile enough. The threshold yields many weaknesses to users. Therefore, we herein propose an efficient top-k geography-text P/S approach that excludes the threshold, called ETGP. Our approach does not need users to set any threshold. Subsequently, the ETGP returns the highest score results to the subscriber without setting a threshold. Therefore, our approach can lessen redundant computations, promote the query integrity rate, and make P/S system easier for the user to use. Comprehensive experiments prove the efficiency of the proposed approach with high facility.

  • The Production of K-0's in p+p Reactions

    Berger-Chen, Jia-Chii   Fabbietti, Laura  

    We present the exclusive analysis of the reactions p+p -> Y+Delta(++)/(p+pi(+))+K-0, where Y stands for the A or E hyperon. The proton-proton measurement was performed with the HADES setup at GSI, Darmstadt, at a kinetic beam energy of 3.5 GeV. A dedicated sideband technique allows to reproduce the non-strange background and its kinematics in the selected data sample. Therefore, it is possible to obtain the background subtracted missing mass distribution MM(p pi(+)pi(+)pi(-)), where we can separate the Lambda from the Sigma(0) channel. From a Monte Carlo simulation of possible reactions we see contributions also by the reactions p + p -> Sigma(+)/Sigma(1385)(+) + p + K-0. The ongoing analysis should provide exclusive cross sections of the mentioned reactions and their angular distributions.

  • Testing hydrodynamic descriptions of p+p collisions at\(\sqrt{s}=7\)TeV

    M. Habich,G. A. Miller,P. Romatschke,W. Xiang  

    In high-energy collisions of heavy ions, experimental findings of collective flow are customarily associated with the presence of a thermalized medium expanding according to the laws of hydrodynamics. Recently, the ATLAS, CMS, and ALICE experiments found signals of the same type and magnitude in ultrarelativistic proton-proton collisions. In this study, the state-of-the-art hydrodynamic model SONIC is used to simulate the systems created in p+p collisions. By varying the size of the second-order transport coefficients, the range of applicability of hydrodynamics itself to the systems created in p+p collisions is quantified. It is found that hydrodynamics can give quantitatively reliable results for the particle spectra and the elliptic momentum anisotropy coefficient . Using a simple geometric model of the proton based on the elastic form factor leads to results of similar type and magnitude to those found in experiment when allowing for a small bulk viscosity coefficient.
