Holgraphy and BMS field theory

We study the key ingredients of a candidate holographic correspondence in an asymptotically flat spacetimes; in particular we develop the kinematical and the classical dynamical data of a BMS invariant field theory living at null infinity.Comment: 3 pages, to appear in the Proceedings for the ``XVI SIGRAV Conference'' in Vietri sul Mare (SA) 13-16 Septembe

Thermal effects in perturbative noncommutative gauge theories

The thermodynamics of gauge theories on the noncommutative plane is studied in perturbation theory. For U(1) noncommutative Yang-Mills we compute the first quantum correction to the ideal gas free energy density and study their behavior in the low and high temperature regimes. Since the noncommutativity scale effectively cutoff interactions at large distances, the theory is regular in the infrared. In the case of U(N) noncommutative Yang-Mills we evaluate the two-loop free energy density and find that it depends on the noncommutativity parameter through the contribution of non-planar diagrams.Comment: 15 pages, harvmac.

Can Catchment Management Deliver Coordination of Resources Management in New South Wales?

In this article, the author examines the problem of the lack of integration of natural resources legislation in NSW and the application of a proposed solution – the catchment management regime. The analysis is conducted by using a case study of Lake Illawarra and its catchment. The operation of the planning system, pollution regulation and the Lake Illawarra Authority are discussed, as well as a number of other regulatory regimes being noted briefly. A history is given of the catchment management system as it has been applied in the Illawarra region. The article concludes by identifying the problems in implementing the catchment management system through the recently enacted Catchment Management Boards

Representation for the Italian Diaspora

In this Audit paper Elisa Arcioni, University of Wollongong, considers the decision to include seats for the Italian diaspora in the Italian parliament.The decision was of even greater significance since it was the results in the Australasian seat that gave the Prodi government its majority in the Senate

Elementary particles, holography and the BMS group

In the context of asymptotically flat space-times, it has been suggested to label elementary particles as unitary irreducible representations of the BMS group. We analyse this idea in the spirit of the holographic principle advocating the use of this definition.Comment: 5 pages, revtex Several comments added, enhanced bibliograph

Director configuration in the twist-bend nematic phase of CB11CB

The director distribution in the nematic phases exhibited by the 100,1100-bis(4-cyanobiphenyl-40-yl)undecane (CB11CB) liquid crystal has been studied in the bulk with the EPR spin probe technique. EPR spectra confirmed the presence of an higher temperature uniaxial nematic phase and of a lower temperature nematic phase in which the director distribution is not uniform. Spectra recorded in the lower temperature nematic phase were not fully compatible with theoretical EPR spectra calculated according to the recently proposed model for the twist-bend phase in which the local domain director twists around an axis with a fixed tilt angle, θ₀, but were well described by a “distributed-tilt” model in which the director has a relatively narrow distribution, centred at θ₀
