COALESCING NEUTRON STARS AS GAMMA RAY BURSTERS ?

We investigate the dynamics and evolution of coalescing neutron stars. The three-dimensional Newtonian equations of hydrodynamics are integrated by the `Piecewise Parabolic Method' However, we do include the effects of the emission of gravitational waves on the hydrodynamics. The properties of neutron star matter are described by the equation of state of Lattimer & Swesty. In addition to the fundamental hydrodynamic quantities, density, momentum, and energy, we follow the time evolution of the electron density in the stellar gas. Energy losses and changes of the electron abundance due to the emission of neutrinos are taken into account by an elaborate ``neutrino leakage scheme'', which employs a careful calculation of the lepton number and energy source terms of all neutrino types. The grid is Cartesian and equidistant with a resolution of 64**3 or 128**3, which allows us to calculate the self-gravity via fast Fourier transforms.Comment: extended abstract contribution to the proceedings of the 17th Texas Symposium, 2 pages, uuencoded compressed postscript

Does Arbitration Blossom When State Courts are Bad?

It is often conjectured that non-state dispute resolution blossoms when state courts are not independent or are perceived as low-quality courts. This conjecture implies a substitutive relationship between state and non-state dispute resolution. An alternative hypothesis argues that both the quality and the frequency of use of these two alternative mechanisms are complementary: societies with high-quality state courts would also be able to provide high-quality non-state dispute resolution. This is the first study that puts these hypotheses to an empirical test. It turns out that the lower the perceived quality of state courts, the less frequently conflicting firms resort to them. Second, firms in common-law countries turn away from state courts significantly more often than firms in civil-law countries. This result sheds doubt on the robustness of results generated within the legal traditions literature. Finally, in states that have created the preconditions for arbitration, businesspeople resort significantly more often to state courts. We interpret this as evidence in favor of the complementarity hypothesis

On a global differential geometric approach to the rational mechanics of deformable media

In the past the rational mechanics of deformable media was largely concerned with materials governed by linear constitutive equations. In recent years, the theory has expanded considerably towards covering materials for which the constitutive equations are inherently nonlinear, and/or whose mechanical properties resemble in some respects those of a fluid and in others those of a solid. In the present article we formulate a satisfactory global mathematical theory of moving deformable media, which includes all these aspects

Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics

A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together with the performance of b-tagging and the trigger. The physics potential for a variety of interesting physics processes, within the Standard Model and beyond, is examined. The study comprises a series of notes based on simulations of the detector and physics processes, with particular emphasis given to the data expected from the first years of operation of the LHC at CERN
