We consider the rheology of soft-core frictionless disks in two dimensions in the neighborhood of the athermal jamming transition. From numerical simulations of bidisperse, overdamped, particles, we argue that the divergence of the viscosity below jamming is characteristic of the hard-core limit, independent of the particular soft-core interaction. We develop a mapping from soft-core to hardcor...

Abstract Background Hardcore smoking behaviours and test of hardening are seldom reported from low-and-middle-income countries (LMICs). We report country-wise changes in behaviors between two sequential surveys explored ecologically the relationship MPOWER scores including hardcore smoking. Methods analysed Global Adult Tobacco Survey (GATS) data done at least five years interval 10 namely Indi...

Das Aufzeichnen von Musik im Tonstudio wird bisher eher selten als eigenständige Form des Musizierens verstanden. David Waldecker untersucht diesen Prozess mit Bezug auf Adorno, praxeologische Ansätze und eigene Feldforschung Bereich Hardcore Jazz. Er zeigt, wie Studio durch dessen technische räumliche Besonderheiten Rolle in der Produktion bestimmte Formen Musikmachens erzeugt werden. Zugleich...

We derive the exact dual representation of the bosonic Hubbard model which takes the form of conserved current loops. The hardcore limit, which corresponds to the quantum spin1 2 Heisenberg antiferromagnet, is also obtained. In this limit, the dual partition function takes a particularly simple form which is very amenable to numerical simulations. In addition to the usual quantities that we can...

We derive an improved mean-field approximation for k-body annihilation reactions kA → inert, for hard-core diffusing particles on a line, annihilating in groups of k neighbors with probability 0 < q ≤ 1. The hopping and annihilation processes are correlated to mimic chemical reactions. Our new mean-field theory accounts for hardcore particle properties and has a larger region of applicability t...

We evaluate the percolation threshold values for a realistic model of continuum segregated systems, where random spherical inclusions forbid the percolating objects, modeled by hardcore spherical particles surrounded by penetrable shells, to occupy large regions inside the composite. We find that the percolation threshold is generally a nonmonotonous function of segregation, and that an optimal...

The Extra Stage Cube (ESC), a single-fault tolerant interconnection network, has been proposed for use in large-scale parallel and distributed computer systems. This paper shows how ESC fault tolerance can be improved by adopting a new reconfiguration policy. The new scheme requires only a small increase system hardware complexity; no logic need be added to the network. Also, a way to eliminate...
