  1. The hybrid mean value of <em>L</em>-functions and a special character sums

    The hybrid mean value of <em>L</em>-functions and a special character sums

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    The main purpose of this paper is using the estimation of the character sums to study the 2k-th power mean of L-functions with the weight of a character sums, and give an interesting asymptotic formula for it.
  2. Fund manager characteristics and performance

    Fund manager characteristics and performance

    Item type: Journal Article • Journal: Investment Analysts Journal
    This study establishes a multitier framework to evaluate how fund manager characteristics systematically affect mutual fund performance. The framework includes three tiers of performance elements: comprehensive performance; return and risk; and timing skill and picking ability. Using performance decomposition, our...
  3. Seasonal and genotypic variation of water-soluble polysaccharide content in leaves of <em>Cyclocarya paliurus</em>

    Seasonal and genotypic variation of water-soluble polysaccharide content in leaves of <em>Cyclocarya paliurus</em>

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Cyclocarya paliurus (Batal) Iljinskaja is an important medicinal woody plant due to numerous bioactive natural products in its leaves. As an important bioactive natural product, water-soluble polysaccharides (WSP) in leaves of C. paliurus possess diverse biological activities, such as hypoglycemic,...
  4. A result on monotonically Lindelöf generalized ordered spaces

    A result on monotonically Lindelöf generalized ordered spaces

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we show that a generalized ordered space representable as the union of two closed monotonically Lindelöf subspaces is monotonically Lindelöf, which partially answers a question [7, Question 2] of Levy and Matveev. In addition, we show that...
  5. Genotypic variation in tree growth and selected flavonoids in leaves of <em>Cyclocarya paliurus</em>

    Genotypic variation in tree growth and selected flavonoids in leaves of <em>Cyclocarya paliurus</em>

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Cyclocarya paliurus is a valuable medicinal tree species in China. However, limited information is available on its genotype selection and cultivation for improvement of growth and health-promoting phytochemicals. To contribute to improved knowledge of the potential use of the species,...
  6. Myths about fundamental indexing<xref ref-type="fn" rid="EN0001"/>

    Myths about fundamental indexing<xref ref-type="fn" rid="EN0001"/>

    Item type: Journal Article • Journal: Investment Analysts Journal
    Fundamental indexing starts from the observation that in a value-weighted portfolio, any overpricing affects the stock’s portfolio weight upward and its typical return downward, and vice versa; but on average the ‘drag’ on the portfolio’s expected return caused by this...
  7. On non-surjective coarse isometries between Banach spaces

    On non-surjective coarse isometries between Banach spaces

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Assume that X, Y are real Banach spaces, Y has uniform convexity of type p (≥ 1), and f: X → Y is a standard coarse isometry. In this paper, we show that if
