Power-law Solutions from Heterotic Strings
In this paper, we search for accelerating power-law and ekpyrotic solutions
in heterotic string theory with NS-NS fluxes compactified on half-flat and
generalized half-flat manifolds. We restrict our searches to the STZ sector of
the theory. We also considered linear order corrections for the
half-flat case. The power-law solutions that we find are neither accelerating
nor ekpyrotic in any of the models.Comment: 21 pages. Major revision. Conclusions change
Three-loop HTLpt thermodynamics at finite temperature and chemical potential
In this proceedings we present a state-of-the-art method of calculating
thermodynamic potential at finite temperature and finite chemical potential,
using Hard Thermal Loop perturbation theory (HTLpt) up to
next-to-next-leading-order (NNLO). The resulting thermodynamic potential
enables us to evaluate different thermodynamic quantities including pressure
and various quark number susceptibilities (QNS). Comparison between our
analytic results for those thermodynamic quantities with the available lattice
data shows a good agreement.Comment: 5 pages, 6 figures, conference proceedings of XXI DAE-BRNS HEP

Representations of swine flu: Perspectives from a Malaysian pig farm
© The Author(s), 2010. This is the author's accepted manuscript. The final published article is available from the link below.Novel influenza viruses are seen, internationally, as posing considerable health challenges, but public responses to such viruses are often rooted in cultural representations of disease and risk. However, little research has been conducted in locations associated with the origin of a pandemic. We examined representations and risk perceptions associated with swine flu amongst 120 Malaysian pig farmers. Thirty-seven per cent of respondents felt at particular risk of infection, two-thirds were somewhat or very concerned about being infected. Those respondents who were the most anxious believed particular societal âout-groupsâ (homosexuals, the homeless and prostitutes) to be at higher infection risk. Although few (4%) reported direct discrimination, 46% claimed friends had avoided them since the swine flu outbreak. Findings are discussed in the context of evolutionary, social representations and terror management theories of response to pandemic threat

Renormalized Entanglement Entropy for BPS Black Branes
We compute the renormalized entanglement entropy (REE) for BPS black
solutions in , 4d gauged supergravity. We find that this quantity
decreases monotonically with the size of the entangling region until it reaches
a critical point, then increases and approaches the entropy density of the
brane. This behavior can be understood as a consequence of the REE being driven
by two competing factors, namely entanglement and the mixedness of the black
brane. In the UV entanglement dominates, whereas in the IR the mixedness takes
over.Comment: 6 pages, 4 figures; v2: Typos fixed, citation and clarifying text
