    In situ photolysis of precursor molecules trapped in a solid parahydrogen matrix has been successfully used in our group to study H atom reactions with other species at temperatures in the range of 1.6 to 4.3 K. At these temperatures, H atoms are known to continuously move through the solid by the H + H2_2 \rightarrow H2_2 + H tunneling exchange reaction. We recently studied the reaction of H atoms with 15^{15}N2_2O and in the preliminary communication of this work,\footnote{F. M. Mutunga, S. E. Follett, D. T. Anderson, \textit{J. Chem. Phys. }\textbf{139}, 151104 (2013).} we reported a very strange non-Arrhenius temperature dependence to the reactionthe reaction only occurs below 2.4 K and not at higher temperatures. This talk will present our subsequent work on the high-resolution infrared spectroscopy of 15^{15}N2_2O molecules trapped in solid parahydrogen with a focus on the ν\nu1_1 + ν\nu3_3 and 2ν\nu1_1 vibrational bands. For both these vibrational bands we observe multiple peaks and the relative intensities of the observed peaks change with temperature over the measured range similar to the temperature dependence of the ν\nu3_3 fundamental reported earlier by Lorenz and Anderson.\footnote{B. D. Lorenz and D. T. Anderson, \textit{J. Chem. Phys. }\textbf{126}, 184506 (2007).} The temperature dependent changes in intensity imply that there are at least two trapping sites which could potentially explain the observed temperature dependence to the H + 15^{15}N2_2O reaction.Made available in DSpace on 2017-01-26T21:36:49Z (GMT).

    In this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report

    Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′

    First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

F. Andreev and I. M. Lifshitz radically changed the way we think about diffusion in cryocrystals by predicting that at sufficiently low temperatures the probability of exchange tunneling of neighboring particles in quantum crystals becomes noticeable such that impurities can move freely through the crystal as narrow-band quasiparticles.\footnote{A. F. Andreev and I. M. Lifshitz, \textit{Sov. Phys. JETP. }\textbf{29}, 1107-1113 (1969).} The term “quantum crystal” was introduced by de Boer in 1948 for substances in which the energy of the zero-point vibrations of the particles is comparable to the total energy of the crystal.\footnote{J. de Boer, \textit{Physica }\textbf{14}, 139-148 (1948).} The main idea put forth by Andreev and Liftshitz is that the rate of quantum diffusion should increase with falling temperatures and should show an inverse dependence on the concentration of impurities. As we will show, the hydrogen atom (H-atom) trapped in a parahydrogen crystal is an ideal candidate for quantum diffusion owing to its small mass and neutral charge. In 2013 our group published a communication\footnote{F. M. Mutunga, S. E. Follett, D. T. Anderson, \textit{J. Chem. Phys. }\textbf{139}, 151104-4 (2013).} on the kinetics of the H + N2_{2}O reaction in solid parahydrogen that showed an anomalous temperature dependence. In these studies we generate the H-atoms as byproducts of the \textit{in situ} photodissociation of N2_{2}O and monitor the subsequent reaction kinetics using rapid scan FTIR. Specifically, if we photolyze N2_{2}O doped parahydrogen solids with 193 nm UV radiation at 4.3 K, we observe little to no reaction; however, if we then slowly reduce the temperature of the sample, we observe an abrupt onset to the reaction at temperatures below 2.4 K. In a number of studies conducted since this original work we have come to a better understanding of the effect of temperature on the reaction and will show data that the rate constant for the H + N2_{2}O reaction shows an inverse dependence on the N2_{2}O concentration. These findings support previous ESR measurements of H-atom quantum diffusion in solid parahydrogen\footnote{T. Kumada et. al., \textit{J. Chem. Phys. }\textbf{116}, 1109-1119 (2002).} and more importantly illustrate how H-atom quantum diffusion impacts the kinetics of these anomalous low temperature, condensed phase reactions

    The vanishing author in computer-generated works: a critical analysis of recent Australian case law

    Get PDF
    Abstract The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

    Appropriate Similarity Measures for Author Cocitation Analysis

    Get PDF
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
