Do correlations create an energy gap in electronic bilayers? Critical analysis of different approaches

This paper investigates the effect of correlations in electronic bilayers on the longitudinal collective mode structure. We employ the dielectric permeability constructed by means of the classical theory of moments. It is shown that the neglection of damping processes overestimates the role of correlations. We conclude that the correct account of damping processes leads to an absence of an energy gap.Comment: 4 page

Pseudo-random operators of the circular ensembles

We demonstrate quantum algorithms to implement pseudo-random operators that closely reproduce statistical properties of random matrices from the three universal classes: unitary, symmetric, and symplectic. Modified versions of the algorithms are introduced for the less experimentally challenging quantum cellular automata. For implementing pseudo-random symplectic operators we provide gate sequences for the unitary part of the time-reversal operator.Comment: 5 pages, 4 figures, to be published PR

The nature and extent of trace element contamination associated with fly-ash disposal sites in the Chisman Creek Watershed

This study was conducted by the Virginia Institute of Marine Science (VIMS) and the Virginia Associated Research Campus (VARC), both branches of the College of William and Mary, to document the nature, extent, and severity of environmental contamination by trace elements from the landfill disposal of fly-ash within the Chisman Creek watershed. Previous work in the area demonstrated that some metals were apparently mobile in the groundwater, and that two nearby household wells were contaminated (Va. SWCB, 1981). These short term studies were limited to the testing of only a few selected contaminants in wells near the fly-ash pits. The goal of our study was to provide a more comprehensive sampling of the basin to delineate the geographical extent of trace element contamination, and to assess whether the levels found there pose a hazard to man or to the terrestrial and aquatic ecosystem. An important aspect of the program is the use of an analytical technique which provides simultaneous measurement of a large number of elements, thereby obviating the need to speculate which elements would be found before the field work was begun. Proton Induced X-ray Emission (PIXE) is such a technique and provided data on 70 elements from each sample collected during this study

‘So presumably things have moved on since then?’ The management of risk allegations in child contact mediation.

Author's draft version. Copyright © Oxford University Press. Final version available online at http://www.oxfordjournals.org/Over the past decade, considerable efforts have been made to ensure that domestic violence and child protection issues are identifi ed, assessed, and managed appropriately within the family justice system. These efforts follow sustained criticism that allegations of harm have been previously overlooked or marginalized within court processes, including in private law cases concerning residence and contact disputes following parental separation. In this article, however, we argue that allegations of harm continue to be marginalised in court-based dispute resolution. Our fi ndings are based on a detailed study of 15 in-court conciliation or court-based dispute resolution sessions. We use conversation analysis to examine in detail precisely how allegations are overlooked or downgraded. We fi nd that conciliators routinely ignore, reframe, or reject allegations unless there is an existing external evidence to support the claim. However, the precise way in which marginalisation occurs is contextual and interactional, shaped not least by the specifi city or persistence of allegations presented by parents. We suggest that the conciliator’s handling of allegations refl ects a particular understanding of their institutional role and tasks that centre upon settlement, contact, and case processing seemingly at the expense of risk management.Data originally collected as part of a Lord Chancellor’s Department funded project.
