    Chiti examines the various forms of European administration and their associated administrative law systems. Chiti recounts the history of administration and of administrative law in the European Community, examines the main types of administrative action in the Community, and highlights the novel elements and the shortcomings of European administrative law today

    The afterglow of gamma ray bursts II: the cases of GRB 970228 and GRB 970508

    Get PDF
    Highly radiative expansion of a relativistic shell is shown to explain all observed features of the afterglows of the two bursts GRB 970228 and GRB 970508. In particular, in the first case the observed time-dependence t^-1.32 of the soft X--ray flux is easily reproduced. The same model, when the surrounding matter density scales as a r^-2, explains the afterglow of GRB 970508}, which may at first sight appear at odds with that of GRB 970228. In particular, it is shown that both the late peak in the optical luminosity and the flat time-dependence of the X--ray luminosity are simultaneously explained by nonuniformity of the surrounding matter, that the observed optical time-delay is correctly reproduced for standard parameter values, and that the time-delay and flux levels of the radio emission are also explained.Comment: 9 pages + 2 figures, AASTEX/LateX needed, submitted to Astrophysical Journal Letter

    Conformal and non Conformal Dilaton Gravity

    Get PDF
    The quantum dynamics of the gravitational field non-minimally coupled to an (also dynamical) scalar field is studied in the {\em broken phase}. For a particular value of the coupling the system is classically conformal, and can actually be understood as the group averaging of Einstein-Hilbert's action under conformal transformations. Conformal invariance implies a simple Ward identity asserting that the trace of the equation of motion for the graviton is the equation of motion of the scalar field. We perform an explicit one-loop computation to show that the DeWitt effective action is not UV divergent {\em on shell} and to find that the Weyl symmetry Ward identity is preserved {\em on shell} at that level. We also discuss the fate of this Ward identity at the two-loop level --under the assumption that the two-loop UV divergent part of the effective action can be retrieved from the Goroff-Sagnotti counterterm-- and show that its preservation in the renormalized theory requires the introduction of counterterms which exhibit a logarithmic dependence on the dilaton field.Comment: LateX, 50 pages.

    Funds Transfer: Boon or Bane to the Viability of Rural Financial Intermediaries

    Get PDF
    Institutional credit set up by the government may not necessarily be the major source of funds in the rural areas. In addition, there may be enough funds to support production and to sustain employment if financial resources are not rained. These insights are just few of authors’ findings in this paper. It suggests that addressing the problem of rural financial drain can open up the opportunities to pursue rural development without eroding the national budgetrural sector, financial intermediaries, funds transfer

    R\'enyi generalizations of quantum information measures

    Get PDF
    Quantum information measures such as the entropy and the mutual information find applications in physics, e.g., as correlation measures. Generalizing such measures based on the R\'enyi entropies is expected to enhance their scope in applications. We prescribe R\'enyi generalizations for any quantum information measure which consists of a linear combination of von Neumann entropies with coefficients chosen from the set {-1,0,1}. As examples, we describe R\'enyi generalizations of the conditional quantum mutual information, some quantum multipartite information measures, and the topological entanglement entropy. Among these, we discuss the various properties of the R\'enyi conditional quantum mutual information and sketch some potential applications. We conjecture that the proposed R\'enyi conditional quantum mutual informations are monotone increasing in the R\'enyi parameter, and we have proofs of this conjecture for some special cases.Comment: 9 pages, related to and extends the results from arXiv:1403.610

    An hphp-Adaptive Newton-Galerkin Finite Element Procedure for Semilinear Boundary Value Problems

    Full text link
    In this paper we develop an hphp-adaptive procedure for the numerical solution of general, semilinear elliptic boundary value problems in 1d, with possible singular perturbations. Our approach combines both a prediction-type adaptive Newton method and an hphp-version adaptive finite element discretization (based on a robust a posteriori residual analysis), thereby leading to a fully hphp-adaptive Newton-Galerkin scheme. Numerical experiments underline the robustness and reliability of the proposed approach for various examples.Comment: arXiv admin note: text overlap with arXiv:1408.522

    Funds Transfer Operations: Boon or Bane to the Viability of Rural Financial Intermediaries?

    Get PDF
    As far as the policies are concerned, the government has been successful in reversing the flow of loanable funds in favor of rural areas through maintenance of agricultural loan quota and deposit retention policies. This paper examines the structure of funds transfer operations of rural-based branches of banks, the factors that determine the volume of transferred funds from one branch to another and the impact of funds transfer operations on the savings mobilization efforts of rural-based financial intermediaries.banking system, rural sector, deposit liabilities, financial intermediaries, funds transfer
