    Detachable circles and temperature-inversion dualities for CFTd_d

    We use a Weyl transformation between S1×Sd−1S^1 \times S^{d-1} and S1×Hd−1/ZS^1 \times \mathcal{H}^{d-1}/\mathbb{Z} to relate a conformal field theory at arbitrary temperature on Sd−1S^{d-1} to itself at the inverse temperature on Hd−1/Z\mathcal{H}^{d-1}/\mathbb{Z}. We use this equivalence to deduce a confining phase transition at finite temperature for large-NN gauge theories on hyperbolic space. In the context of gauge/gravity duality, this equivalence provides new examples of smooth bulk solutions which asymptote to conically singular geometries at the AdS boundary. We also discuss implications for the Eguchi-Kawai mechanism and a high-temperature/low-temperature duality on Sd−1S^{d-1}.Comment: 21 page

    Electrochemically Deposited Cadmium Electrode for Sealed Ni-cd Cells

    An investigation into the work on electrochemical cadmium deposition processes is describred. A beaker impregnation system is constructed to investigate the practical limits of loading and the effect of various process parameters. Reasonably high loadings of cadmium are obtained and the process appears amenable to tight control and the production of uniform consistent electrodes. A pilot impregnation facility is built to further investigate electrodeposition processes. Both the inert anode and consummable anode processes are investigated. Results of this evaluation and an analysis of associated problems are presented

    The Formation of Crystalline Dust in AGB Winds from Binary Induced Spiral Shocks

    Full text link
    As stars evolve along the Asymptotic Giant Branch, strong winds are driven from the outer envelope. These winds form a shell, which may ultimately become a planetary nebula. Many planetary nebulae are highly asymmetric, hinting at the presence of a binary companion. Some post-Asymptotic Giant Branch objects are surrounded by torii of crystalline dust, but there is no generally accepted mechanism for annealing the amorphous grains in the wind to crystals. In this Letter, we show that the shaping of the wind by a binary companion is likely to lead to the formation of crystalline dust in the orbital plane of the binary.Comment: Submitted to ApJ

    Defining pain and painful sentience in animals

    Get PDF
    Sentience is essential to most definitions of pain, including a detailed definition invoked by Sneddon et al. to argue that adult and perhaps larval fish feel pain. Because proving painful sentience in non-human animals is not feasible, multiple lines of indirect evidence are needed to implicate pain. This commentary examines the list of 17 criteria used by Sneddon et al. to conclude that fish have conscious pain. The criteria include tests of nociceptive, motivational, and cognitive properties useful for revealing pain-like states that can be understood biologically and be related evolutionarily to human pain. However, additional research is needed to define the crucial aversive component of pain-like states in fish
