Standard methods in lattice QCD consist of calculating various hadronic amplitudes by tying together appropriate combinations of quark propagators calculated on an ensemble of Monte Carlo generated gauge fields. A number of recent lattice QCD calculations have focused increasing attention on the role of low-lying eigenmodes of the Dirac operator in typical background gauge fields. The decomposi...

We discuss here Quantum molecular dynamics models (QMD) and Dual Parton Models (DPM and QGSM). We compare RHIC data to DPM–models and we present a (Cosmic ray oriented) model comparison. The emphasis of this contribution is to high energies, therefore, QMD non–relativistic models (E < 2AGeV) are not treated here. The first relativistic QMD model was RQMD [1]. This model is no longer supported s...

The vision of a network of seamlessly integrated distributed services that provide access to computation, data, and other resources is known simply as the 'Grid'. This paper proposes an evolutionary process to standardizing services and protocols necessary to support applications on the Grid. An architecture with a minimal set of services to support interoperable High‐Performance Computing in a...

We have conducted multiwavelength observations of several northern TeV blazars employing the ground-based γ-ray observatories MAGIC and HESS, the optical KVA telescope, and the Suzaku X-ray satellite. The data taken in 2006 establish measurements of the contemporaneous spectral energy distributions of the rapidly variable blazar emission over a wide range of frequencies. Results allow us to tes...

Event-to-event fluctuations of the spatial patterns of the final states of high-enery collisions, referred to as erraticity, are studied for the data generated by a soft-interaction model called ECOMB. The moments Cp,q do not show simple power-law dependences on the bin size. New measures of erraticity are proposed that generalizes the bin-size dependence. The method should be applied not only ...

Millions of computers are now connected together by the Internet. At a fast pace, applications are taking proot of these new capabilities, and become parallel and distributed , e.g. applets on the WWW or agent technology. As we live in a world with nite resources, an important challenge is to be able to control computations in such an environment. For instance, a user might like to suspend a co...

Scheduling the power exchange between a population of heterogeneous distributed energy resources and corresponding upper level grid is an important control problem in systems. A key challenge large number (partially uncertain) variables that increase computational burden complicate structured consideration uncertainties. Reducing decision by means aggregation can help alleviate these issues. Ho...
