    Kyrgyzstan's 'manas' epos millennium celebrations : post-colonial resurgence of Turkic culture and the strategic marketing of cultural tourism

    Get PDF
    The paper addresses the symbolic nature of the Manas epos and its influence on both the unification of Kyrgyzstan and the enhancement of the country's national and Turkic identity. The case of the Manas epos millennium celebrations event is then used to illustrate the relationship between the uses of the Manas 'legend' in the construction of a national identity and in the positioning of the cultural tourism product. The paper subsequently assess the potential usefulness of the Manas epos in the creation of a destination image for Kyrgyzstan and in the positioning of Kyrgyzstan in the global tourism marketplace

    Field Theory of Many-Body Lindbladian Dynamics

    Full text link
    We review and further develop the Keldysh functional integral technique for the study of Lindbladian evolution of many-body driven-dissipative quantum systems. A systematic and pedagogical account of the dynamics of generic bosonic and fermionic Lindbladians is presented. Our particular emphasis is on unique properties of the stationary distribution function, determined by the Lyapunov equation. This framework is applied to study examples of Lindbladian dynamics in the context of band theory, disorder, collisionless collective modes, and mean-field theory

    Surface roughness interpretation of 730 kg days CRESST-II results

    Full text link
    The analysis presented in the recent publication of the CRESST-II results finds a statistically significant excess of registered events over known background contributions in the acceptance region and attributes the excess to a possible Dark Matter signal, caused by scattering of relatively light WIMPs. We propose a mechanism which explains the excess events with ion sputtering caused by 206Pb recoils and alpha particles from 210Po decay, combined with realistic surface roughness effects.Comment: 15 pages, 6 figures. v2: corrected quenching factor discussion. v3: corrected references. v4: added reference

    A Legal Update on Environmental Justice in Virginia: Where are We Now?

    Get PDF
    Environmental justice (“EJ”) is rapidly evolving in Virginia while people are still trying to understand what EJ actually means. As a result, regulators are unsure of how to incorporate environmental justice in their decisionmaking process while the regulated are uncertain of how to proceed in the ever-changing political, social, and regulatory landscape. This article gives an overview of EJ’s evolution in Virginia, synthesizing notable environmental justice legal decisions; providing supplementary research on environmental justice studies, workgroups, and reports; and offering several predictions on EJ’s fate in the Commonwealth

    Screening and surveillance CT abdomen/pelvis for metastases in patients with soft-tissue sarcoma of the extremity

    Objectives The clinical utility of routine cross sectional imaging of the abdomen and pelvis in the screening and surveillance of patients with primary soft-tissue sarcoma of the extremities for metastatic disease is controversial, based on its questionable yield paired with concerns regarding the risks of radiation exposure, cost, and morbidity resulting from false positive findings. Methods Through retrospective review of 140 patients of all ages (mean 53 years; 2 to 88) diagnosed with soft-tissue sarcoma of the extremity with a mean follow-up of 33 months (0 to 291), we sought to determine the overall incidence of isolated abdominopelvic metastases, their temporal relationship to chest involvement, the rate of false positives, and to identify disparate rates of metastases based on sarcoma subtype. Results A total of four patients (2.9%) exhibited isolated abdominopelvic metastatic disease during the surveillance period. In all cases of concomitant chest and abdominopelvic disease, chest involvement preceded abominopelvic involvement. There was a significant false positive rate requiring invasive workup. Conclusions In the setting of a relative paucity of evidence concerning a rare disease process and in difference to recently published investigations, we add a clinical cohort not supportive of routine cross sectional imaging of the abdomen and pelvis

    An exploration of some aspects of mystery

    Get PDF
    This thesis project consists of twenty-four paintings, drawings and lithographs dealing with three sub-themes of the larger subject of mystery: the mystery of existence; the mystery of religion; the mystery of the unknown. These themes are explored through manipulations of light, color, compositional arrangement and painting and drawing techniques

    Noise-induced flow in quasigeostrophic turbulence with bottom friction

    Get PDF
    Randomly-forced fluid flow in the presence of scale-unselective dissipation develops mean currents following topographic contours. Known mechanisms based on the scale-selective action of damping processes are not at work in this situation. Coarse-graining reveals that the phenomenon is a kind of noise-rectification mechanism, in which lack of detailed balance and the symmetry-breaking provided by topography play an important role.Comment: 8 pages Revtex, no figures.

    Massive Quiescent Cores in Orion: Dynamical State Revealed by High-Resolution Ammonia Maps

    Full text link
    We present combined VLA and Green Bank Telescope images of \ammonia\ inversion transitions (1,1) and (2,2) toward OMC2 and OMC3. We focus on the relatively quiescent Orion cores, which are away from the Trapezium cluster and have no sign of massive protostars nor evolved star formation, such as IRAS source, water maser, and methanol maser. The 5\arcsec\ angular resolution and 0.6km s−10.6 \rm{}km\,s^{-1} velocity resolution of these data enable us to study the thermal and dynamic state of these cores at ∌0.02pc\sim{}0.02 \rm{}pc scales, comparable to or smaller than those of the current dust continuum surveys. We measure temperatures for a total of 30 cores, with average masses of 11\,\Ms, radii of 0.039pc0.039 \rm{}pc, virial mass ratio Rvirˉ\bar{R_{vir}} = 3.9, and critical mass ratio RCˉ\bar{R_{C}} = 1.5. Twelve sources contain \textit{Spitzer} protostars. The thus defined starless and protostellar subsamples have similar temperature, line width, but different masses, with an average of 7.3\,\Ms for the former and 16\,\Ms for the latter. Compared to others Gould Belt dense cores, mores Orion cores have a high gravitational-to kinetic energy ratio and more cores have a larger thant unity critical mass ratio. Orion dense cores have velocity dispersion similar to those of cores in low-mass star-forming regions but larger masses for fiven size. Some cores appear to have truly supercritical gravitational-to-kinetic energy ratios, even when considering significant observational uncertainties: thermal and non-thermal gas mothins alone cannot prevent collapse.Comment: Accepted by ApJ, ApJ2013...768...L
