    Detecting Nutau Oscillations as PeV Energies

    Full text link
    It is suggested that a large deep underocean neutrino detector, given the presence of significant numbers of neutrinos in the PeV range as predicted by various models of Active Galactic Nuclei, can make unique measurements of the properties of neutrinos. It will be possible to observe the existence of the nu_tau, measure its mixing with other flavors, in fact test the mixing pattern for all three flavors based upon the mixing parameters suggested by the atmospheric and solar neutrino data, and measure the nu_tau cross section. The key signature is the charged current nu_tau interaction, which produces a double cascade, one at either end of a minimum ionizing track. At a few PeV these cascades would be separated by roughly 100 m, and thus be easily resolvable in DUMAND and similar detectors. Future applications are precise neutrino astronomy and earth tomography.Comment: 10 Pages, 2 figs included, 15 May 1994, Preprint DUMAND-3-9

    Entrepreneurial Capabilities and Resources: Sustainable Competitive Advantage through Innovation and Opportunism

    Get PDF
    Firm resource theory specifies the conditions under which resources and capabilities may lead to sustainable competitive advantage. Using the emerging organization as an example, we use firm resource theory to identify some of the resources important to the entrepreneurial capabilities of innovation and opportunism

    Face Detection with the Faster R-CNN

    The Faster R-CNN has recently demonstrated impressive results on various object detection benchmarks. By training a Faster R-CNN model on the large scale WIDER face dataset, we report state-of-the-art results on two widely used face detection benchmarks, FDDB and the recently released IJB-A.Comment: technical repor

    KM3NeT: Towards a km3 Mediterranean Neutrino Telescope

    Get PDF
    The observation of high-energy extraterrestrial neutrinos is one of the most promising future options to increase our knowledge on non-thermal processes in the universe. Neutrinos are e.g. unavoidably produced in environments where high-energy hadrons collide; in particular this almost certainly must be true in the astrophysical accelerators of cosmic rays, which thus could be identified unambiguously by sky observations in "neutrino light". To establish neutrino astronomy beyond the detection of single events, neutrino telescopes of km3 scale are needed. In order to obtain full sky coverage, a corresponding detector in the Mediterranean Sea is required to complement the IceCube experiment currently under construction at the South Pole. The groups pursuing the current neutrino telescope projects in the Mediterranean Sea, ANTARES, NEMO and NESTOR, have joined to prepare this future installation in a 3-year, EU-funded Design Study named KM3NeT. This report will highlight some of the physics issues to be addressed with the KM3NeT detector and will outline the path towards its realisation, with a focus on the upcoming Design Study.Comment: Presented at VLVnT2 Workshop, Catania, Siciliy, Italy, 8-11 Nov 200
