    Sensitivity to chemically diverse phagostimulants in a single gustatory neuron of a polyphagous caterpillar (2000)

    Notes: Abstract Caterpillars of the arctiid moth, Grammia geneura, are polyphagous, but species of Plantago are amongst their preferred food plants. A neuron in the medial styloconic sensillum on the galea has been shown to have a general phagostimulatory function. Experiments with binary mixtures and cross-adaptation have demonstrated that it responds to some sugars, to several amino acids, and also to catalpol. Catalpol is a plant secondary compound in Plantago and a phagostimulant for the caterpillars. The possible significance of combining sensitivity to nutrient compounds with sensitivity to a secondary compound is discussed.

    Exploration geochemistry—Distribution of elements and recognition of anomalies (1975)
    Springer
    Mathematical geology 7 (1975), S. 415-446

    Notes: Abstract The exploration geochemist faces a serious problem in reconciling theoretical statistics with the empirical distribution of elements in materials in the earth's crust. The results of computer-simulation experiments being conducted by the Exploration Geochemistry Group at the University of New Brunswick illustrate some of the problems of the relation between frequency distributions and spatial distributions of elements and raise some interesting questions about sampling patterns and physical size of samples. Most importantly, the simulation experiments and empirical examples support the contention that attempts to make an assumption of normality more efficient by performing log transformations on positively skewed data may defeat the purpose of statistical analysis for exploration work. New developments in computer-data presentation and interpretation, including population sorting and classification, illustrate the increasing use of the computer in exploration geochemistry.

    High-spin states in neutron-rich Dy isotopes populated in deep-inelastic reactions (2001)
    Springer
    The European physical journal 10 (2001), S. 41-47 
    Details
    ISSN: 1434-601X
    Keywords: PACS. 23.20.Lv Gamma transitions and level energies – 27.70.+q 150 ?A? 189

    Topics: Physics
    Notes: Abstract: High-spin states in neutron-rich Dy isotopes, populated in deep-inelastic processes produced by the interaction of 234 MeV 37Cl ions with a 160Gd target, have been studied using the highly sensitive EUROBALL IV gamma-ray detector array. The previously known level schemes for 159,160,161,162Dy have been extended to significantly higher spin ( ? 30?) and the i 13/2 band crossing in 159Dy has been observed for the first time. The experimental results are discussed within the framework of cranked shell model and projected shell model calculations with particular reference to the observed delayed band crossing in 162Dy.
