Schema.

This thesis supports the Master of Fine Arts exhibition at the Slocumb Galleries in Ball Hall at East Tennessee State University, from February 23rd through February 27th 2009. The exhibition is comprised of eight graphite drawings, one ink drawing, eight vinyl prints, two hundred sixty lenticular prints, over fifty digital inkjet prints, and one video installation. The exhibition presents the artist\u27s exploration into using drawings and prints as installation as they relate to quantum physics and universal scale. Subjects discussed, on a project-by-project basis, include thought, ideas, methods, influences, and process by which the work in the exhibition was achieved

The federal plan for health science and technology’s response to the opioid crisis: understanding sex and gender differences as part of the solution is overlooked

Abstract The Fast-Track Action Committee on (the) Health Science and Technology Response to the Opioid Crisis recently released their draft report for public comment. This report provides the “roadmap” for a coordinated federal research and development response to the opioid crisis. Other than noting the important concerns regarding maternal and neonatal exposure to opioids, the report overlooks the laboratory, clinical, and epidemiological data that inform the need for further research on sex and gender differences in opioid addiction that have critical gender-based treatment and prevention implications. As we embark on research and development, investigations into the neurobiology of pain, opioid use, and addiction must include both females and males in model systems and, similarly, psychological and sociocultural investigations must study women and men. All data should be reported by sex and gender so that gender-specific treatment and prevention strategies derived from this research are provided to practitioners and the public. We encourage biomedical researchers and clinical care providers, as well as the public, to insist that a successful response to the opioid crisis should highlight the importance of understanding sex and gender differences in the current opioid epidemic.https://deepblue.lib.umich.edu/bitstream/2027.42/146784/1/13293_2018_Article_215.pd

The CFH Optical PDCS survey (COP) I: The Data

This paper presents and gives the COP (COP: CFHT Optical PDCS; CFHT: Canada-France-Hawaii Telescope; PDCS: Palomar Distant Cluster Survey) survey data. We describe our photometric and spectroscopic observations with the MOS multi-slit spectrograph at the CFH telescope. A comparison of the photometry from the PDCS (Postman et al. 1996) catalogs and from the new images we have obtained at the CFH telescope shows that the different magnitude systems can be cross-calibrated. After identification between the PDCS catalogues and our new images, we built catalogues with redshift, coordinates and V, I and Rmagnitudes. We have classified the galaxies along the lines of sight into field and structure galaxies using a gap technique (Katgert et al. 1996). In total we have observed 18 significant structures along the 10 lines of sight.Comment: 40 pages, 13 figures, accepted in A

A Turn-over in the Galaxy Luminosity Function of the Coma Cluster Core?

Our previous study of the faint end (R$\leq$21.5) of the galaxy luminosity function (GLF) was based on spectroscopic data in a small region near the Coma cluster center. In this previous study Adami et al. (1998) suggested, with moderate statistical significance, that the number of galaxies actually belonging to the cluster was much smaller than expected. This led us to increase our spectroscopic sample. Here, we have improved the statistical significance of the results of the Coma GLF faint end study (R$\leq$22.5) by using a sample of 85 redshifts. This includes both new spectroscopic data and a literature compilation. The relatively small number of faint galaxies belonging to Coma that was suggested by Adami et al. (1998) and Secker et al. (1998) has been confirmed with these new observations. We also confirm that the color-magnitude relation is not well suited for finding the galaxies inside the Coma cluster core, close to the center at magnitudes fainter than R$\sim$19. We show that there is an enhancement in the Coma line of sight of field galaxies compared to classical field counts. This can be explained by the contribution of groups and of a distant $z\sim 0.5$ cluster along the line of sight. The result is that the Coma GLF appears to turn-over or at least to become flat for the faint galaxies. We suggest that this is due to environmental effects.Comment: 8 pages, 6 postscript figures, accepted in A&A, new table 1, updated figure

Search for neutrinos from transient sources with the ANTARES telescope and optical follow-up observations

The ANTARES telescope has the opportunity to detect transient neutrino sources, such as gamma-ray bursts, core-collapse supernovae, flares of active nuclei... To enhance the sensitivity to these sources, we have developed a new detection method based on the optical follow-up of "golden" neutrino events such as neutrino doublets coincident in time and space or single neutrinos of very high energy. The ANTARES Collaboration has therefore implemented a very fast on-line reconstruction with a good angular resolution. These characteristics allow to trigger an optical telescope network; since February 2009. ANTARES is sending alert trigger one or two times per month to the two 25 cm robotic telescope of TAROT. This follow-up of such special events would not only give access to the nature of the sources but also improves the sensitivity for transient neutrino sources.Comment: 3 pages, 3 figures, Proceedings of the 31st ICRC, Lodz, Polan, July 200

The Infrared Luminosity Function of Galaxies in the Coma Cluster

An infrared survey of the central 650 arcmin$^2$ of the Coma cluster is used to determine the $H$ band luminosity function for the cluster. Redshifts are available for all galaxies in the survey with $H < 14.5$, and for this sample we obtain a good fit to a Schechter function with $H^*=11.13$ and $\alpha=-0.78$. These luminosity function parameters are similar to those measured for field galaxies in the infrared, which is surprising considering the very different environmental densities and, presumably, merger histories for field galaxies. For fainter galaxies, we use two independent techniques to correct for field galaxy contamination in the cluster population: the $B-R$ color-magnitude relation and an estimate for the level of background and foreground contamination from the literature. Using either method we find a steep upturn for galaxies with $14 < H < 16$, with slope $\alpha \simeq 1.7$.Comment: 15 pages, 2 figures Accepted by ApJ Letter

Dynamical and content evolution of a sample of clusters from z~0 to z~0.5

In this paper, we present an analysis of the dynamics and segregation of galaxies in rich clusters from z~0.32 to z~0.48 taken from the CFHT Optical PDCS (COP) survey and from the CNOC survey (Carlberg et al. 1997). Our results from the COP survey are based upon the recent observational work of Adami et al. (2000) and Holden et al. (2000) and use new spectroscopic and photometric data on six clusters selected from the Palomar Distant Cluster Survey (PDCS; Postman et al. 1996). We have compared the COP and CNOC samples to the ESO Nearby Abell Cluster Survey (ENACS: z~0.07). Our sample shows that the z<0.4 clusters have the same velocity dispersion versus magnitude, morphological type and radius relationships as nearby Abell clusters. The z~0.48 clusters exhibit, however, departures from these relations. Furthermore, there appears to be a higher fraction of late-type (or bluer, e.g. Butcher and Oemler, 1984) galaxies in the distant clusters compared to the nearby ones. The classical scenario in which massive galaxies virialize before they evolve from late into early type explain our observations. In such a scenario, the clusters of our sample began to form before a redshift of ~0.8 and the late-type galaxy population had a continuous infall into the clusters.Comment: 11 pages, 4 figures, accepted in A&
