Holography for chiral scale-invariant models

Deformation of any d-dimensional conformal field theory by a constant null source for a vector operator of dimension (d + z -1) is exactly marginal with respect to anisotropic scale invariance, of dynamical exponent z. The holographic duals to such deformations are AdS plane waves, with z=2 being the Schrodinger geometry. In this paper we explore holography for such chiral scale-invariant models. The special case of z=0 can be realized with gravity coupled to a scalar, and is of particular interest since it is related to a Lifshitz theory with dynamical exponent two upon dimensional reduction. We show however that the corresponding reduction of the dual field theory is along a null circle, and thus the Lifshitz theory arises upon discrete light cone quantization of an anisotropic scale invariant field theory.Comment: 62 pages; v2, published version, minor improvements and references adde

Wet deposition flux of trace elements to the Adirondack region

Wet deposition samples from two locations in the Adirondack region of New York were analyzed for trace elemental composition by instrumental neutron activation analysis. Annual fluxes of the measured species were determined by precipitation-weighted and linear-regression methods. Despite several episodes of high deposition fluxes, the cumulative areal wet deposition of trace elements increased fairly linearly (r(2)>0.9) over the two year sampling period at both sites. This implies that short duration sampling programs may be used to estimate long-term fluxes and cumulative wet deposition impacts. Based on the magnitude of their fluxes. the measured species have been divided into four groups: acidic onions, electroneutral balancing cations. and minor and trace elements anthropogenic origin

Penetrating eye injuries from southeastern Anatolia region of Turkey

Objectives. This study analysed 420 patients with penetrating eye injuries who presented for treatment at the Eye Clinic of Dicle University Hospital in Turkey. The aim of the study was to identify preventable risk factors. Methods. A retrospective evaluation of patients who presented between January 1995 and December 2000 was undertaken. Cases were examined with regard to age, sex, profession, which eye was traumatized, reason for the trauma, nature of the trauma, time between injury and operation, and accompanying pathologies. Results. This study found that most penetrating eye injuries occurred in children aged 0-15 years, and these were mainly caused by accidents during play. For patients aged 16-60 years, penetrating eye injuries were mainly caused by work-related accidents. Conclusion. Most penetrating eye injuries were caused by preventable accidents. Many accidents and their resulting injuries could have been prevented by education, greater intensive care and workplace safety. (C) 2004 The Royal Institute of Public Health.
