    Introduction: ‱Urinary incontinence (UI) is a common syndrome that often goes unreported and undiagnosed ‱As calls to action from the National Institute on Aging and American Geriatrics Society suggest, the healthcare workforce must work interprofessionally to meet the needs of people with UI ‱Understanding the challenges of and opportunities for improving continence care in Virginia is a first step ‱The primary goal of this study was to assess changes in awareness of and confidence in providing interprofessional UI care after participating in an interactive worksho

    Streaking and Wigner time delays in photoemission from atoms and surfaces

    Get PDF
    Streaked photoemission metrology allows the observation of an apparent relative time delay between the detection of photoelectrons from different initial electronic states. This relative delay is obtained by recording the photoelectron yield as a function of the delay between an ionizing ultrashort extended ultraviolet (XUV) pulse and a streaking infrared (IR) pulse. Theoretically, photoemission delays can be defined based on i) the phase shift the photoelectron wavefunction accumulates during the release and propagation of the photoelectron (``Wigner delay") and, alternatively, ii) the streaking trace in the calculated photoemission spectrum (``streaking delay"). We investigate the relation between Wigner and streaking delays in the photoemission from atomic and solid-surface targets. For solid targets and assuming a vanishing IR-skin depth, both Wigner and streaking delays can be interpreted as an average propagation time needed by photoelectrons to reach the surface, while the two delays differ for non-vanishing skin depths. For atomic targets, the difference between Wigner and streaking delays depends on the range of the ionic potential.Comment: 9 pages, 12 figures, submitted to Phys. Rev.

    Status report of the CERN light shining through the wall experiment with microwave axions and related aspects

    One way to proof or exclude the existence of axion like particles is a microwave light shining through the wall experiment. In this publication we will emphasize on the engineering aspects of such a setup, currently under development at CERN. One critical point, to achieve meaningful results, is the electromagnetic shielding between axion-emitter and -receiver cavity, which needs to be in the order of 300 dB to improve over existing experimental bounds. The RF leakage or electromagnetic crosstalk between both cavities must be well controlled and quantified during the complete duration of the experiment. A very narrow band (in the 10^-6 Hz range) homodyne detection method is used to reveal the axion signal from background thermal noise. The current status of the experiment is presented.Comment: Contributed to the "7th Patras Workshop on Axions, WIMPs and WISPs", Mykonos June 26 - July 1 201

    To detect or exclude the existence of hidden sector photons or axion like particles, a table-top "microwaves shining through the wall" experiment has been set up at CERN. An overview of the experimental layout is given, the technical challenges involved are reviewed and the measurement procedure including data-evaluation and its results to date are shown.Comment: Contributed to the 8th Patras Workshop on Axions, WIMPs and WISPs, Chicago, July 18-22, 201

    Aus Liebe sterben : Inszenierung und Perspektivierung von Elyes Liebestod in Rudolfs von Ems â€șWillehalm von Orlensâ€č

    Get PDF
    [D]ie Schlusspartie im ersten Buch des â€șWillehalm von Orlensâ€č Rudolfs von Ems [
] beginnt unmittelbar mit der breit geschilderten Totenklage ĂŒber den ermordeten FĂŒrsten Wilhelm [
]. Mitten in diesem Leid, das in Rede und GebĂ€rde zum Ausdruck gebracht wird, geschieht im â€șWillehalm von Orlensâ€č das Außerordentliche: Elye, Wilhelms Frau, stirbt aus ĂŒbergroßem Schmerz an der Leiche ihres Mannes. Obwohl solch ein „Tod an gebrochenem Herzen“ außerhalb der normalen lebensweltlichen Erfahrung steht und als Faktum des Sterbens an sich keine ‘moralische’ Komponente beinhaltet, birgt er ein gewisses Konfliktpotenzial [
]. Wie versucht nun der Text diesen beunruhigenden, ‘unfassbaren’ Tod literarisch darzustellen und damit fassbar zu machen? Werden die Wertekonflikte, die bei jedem Liebestod unweigerlich mitschwingen, angesprochen, beurteilt und wird versucht, sie zu harmonisieren? Diese Fragen werden umso brisanter, gerade wenn man die generell didaktische Tendenz des Romans berĂŒcksichtigt, der in der Forschung als ‘FĂŒrstenlehre’ fĂŒr den jungen Staufer Konrad IV. gilt. Eine Antwort darauf lohnt sich in den Klagen zu suchen, die den Liebestod von der HandlungsfĂŒgung her umrahmen. Sie finden sich im â€șWillehalm von Orlensâ€č auf verschiedene Personen aufgeteilt: die Perspektive auf den Tod resp. Liebestod vervielfĂ€ltigt sich, dieser gewinnt unter den verschiedenen Blickwinkeln unterschiedliche Facetten – so auch seine Bewertung. [
] Daneben ist es aber fĂŒr ein erweitertes VerstĂ€ndnis von Aussage und Funktion unabdingbar zu erörtern, w i e diese Klagen ‘in Szene’ gesetzt werden, d. h. wie sie und die klagenden Personen im Diskurs zur Darstellung kommen: Erst in dieser Zusammenschau darf man eine ĂŒber die Textebene hinausreichende Interpretation der Bewertung der Liebestodproblematik in dieser Textpassage versuchen und damit eine mögliche Antwort auf die Frage finden, welche ‘Lehre’ denn die ErzĂ€hlung und Kommentierung der Ereignisse rund um Elyes Liebestod transportieren könnten
