We extend the duality between massive and topologically massive antisymmetric tensor gauge theories in arbitrary space-time dimensions to include topological defects. We show explicitly that the condensation of these defects leads, in 4 dimensions, to confinement of electric strings in the two dual models. The dual phase, in which magnetic strings are confined is absent. The presence of the con...

This paper presents a language of update programs that integrates logical queries, bulk updates and hypothetical reasoning in a seamless manner. There is no syntactic or semantic distinction between queries and updates. Update programs extend logic programs with negation in both syntax and semantics. Users can specify bulk updates in which an arbitrary update is applied simultaneously for all a...

In order to make quantitative predictions for jet cross sections in perturbative QCD, it is essential to calculate them to next-to-leading accuracy. This has traditionally been an extremely laborious process. Using a new formalism, imaginatively called the dipole formalism, we are able to construct a completely general algorithm for next-to-leading order calculations of arbitrary jet quantities...

In this paper we prove that over local or global fields of characteristic 0, the Corestriction Principle holds for kernel and image of all maps which are connecting maps in group cohomology and the groups of R-equivalences. Some related questions over arbitrary fields of characteristic 0 are also discussed. AMS Mathematics Subject Classification (1991): Primary 11E72, Secondary 18G50, 20G10 Pla...

Abstract The aim of this paper is to introduce, elucidate and defend the usefulness a variant grounding, or metaphysical explanation, that has feature grounds explain some states affairs one them obtains without explaining which obtains. I will dub arbitrary grounding . After informally elucidating basic idea in first section, provide three hypotheses are best formulated terms second section. t...

In this paper, the free vibration analysis of moderately thick rectangular plates axially moving with constant velocity and subjected to uniform in-plane loads is investigated by the spectral finite element method. Two parallel edges of the plate are assumed to be simply supported and the remaining edges have any arbitrary boundary conditions. Using Hamilton’s principle, three equations of moti...

In this paper, I revisit the discussion on workplace studies in computersupported cooperative work (CSCW). Mainly this discussion has debated the designrelated outcome, direct or indirect, of doing ethnographically informed studies of workplaces. There is, however, no clear definition on what counts as a workplace study in a CSCW context. Sometimes a workplace study signifies ethnographic field...
