  1. On the Maximal Function for the Generalized Ornstein-uhlenbeck Semigroup.

    On the Maximal Function for the Generalized Ornstein-uhlenbeck Semigroup.

    Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Jorge Betancor Liliana Forzani Roberto Scotto WilfredoO. Urbina
    In this note we consider the maximal function for the generalized Ornstein-Uhlenbeck semigroup in R associated with the generalized Hermite polynomials {H μ n } and prove that it is weak type (1,1) with respect to dλ...
  2. Factors associated with conception among a sample of HIV-positive women at a hospital in Uganda

    Factors associated with conception among a sample of HIV-positive women at a hospital in Uganda

    Item type: Journal Article • Journal: African Journal of AIDS Research • Authors: Peter Kisakye --- Department of Obstetrics and Gynecology, Uganda Wilfred Owot Akena --- Department of Obstetrics and Gynecology, Uganda G Kikampikaho --- Department of Obstetrics and Gynecology, Uganda DanK Kaye --- Department of Obstetrics and Gynecology, Uganda
    Conception among HIV-positive individuals is an important health and social issue. However, the proportion of HIV-positive women who conceive while being aware of their serostatus and the factors that influence this decision is not well documented. In a cross-sectional study,...
  3. On Gaussian Lipschitz spaces and the boundedness of fractional integrals and fractional derivatives on them

    On Gaussian Lipschitz spaces and the boundedness of fractional integrals and fractional derivatives on them

    Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: A. Eduardo Gatto --- Department of Mathematical Sciences, USA Wilfredo O. Urbina R. --- Department of Mathematics and Actuarial Sciences, USA
    The main purpose of this paper is to study the boundedness of Gaussian fractional integrals and derivatives associated to Hermite polynomial expansions on Gaussian Lipschitz spaces Lipα (γ). To get these results we introduce formulas for these operators in terms...
  4. Drivers of commercialization: A case of indigenous chicken production in northern Uganda

    Drivers of commercialization: A case of indigenous chicken production in northern Uganda

    Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Irene Penninah Aryemo --- Department of Rural Development and Agribusiness, Uganda Irine Akite --- Department of Rural Development and Agribusiness, Uganda Enos Katya Kule --- Department of Rural Development and Agribusiness, Uganda Donald Rugira Kugonza --- Department of Agricultural Production, College of Agricultural & Environmental Sciences (CAES), Uganda Marion Wilfred Okot --- Department of Animal Production and Range Management, Uganda Basil Mugonola --- Department of Rural Development and Agribusiness, Uganda
    This study was conducted to assess the drivers of commercialization and profitability among the smallholder farmers of indigenous chickens (IC) in northern Uganda. A market index was constructed to measure the proportion of IC marketed as a proxy for commercialization...
  5. Some new results on <em>H</em> summability of Fourier series

    Some new results on H summability of Fourier series

    Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Calixto P. Calderón --- Department of Mathematics, USA A. Susana Coré --- Department of Mathematics, USA Wilfredo O. Urbina --- Department of Mathematical and Actuarial Sciences, USA
    In this paper we shall be concerned with Hα summability, for 0 < α ≤ 2 of the Fourier series of arbitrary L1([−π, π]) functions. The methods employed here are a modification of the real variable ones introduced by J...
  6. Hardy-Littlewood maximal operator on variable Lebesgue spaces with respect to a probability measure

    Hardy-Littlewood maximal operator on variable Lebesgue spaces with respect to a probability measure

    Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Jorge Moreno --- , Venezuela Ebner Pineda --- , Ecuador Luz Rodriguez --- , Ecuador Wilfredo O. Urbina --- , USA
    In this paper we are going to prove that the Hardy-Litllewood maximal operators on variable Lebesgue spaces L p(·)(µ) with respect to a probability Borel measure µ, are weak type and strong type for two conditions of regularity on the...
  7. Factors that influence Africa&rsquo;s refusal and discontinuation of mobile applications use

    Factors that influence Africa’s refusal and discontinuation of mobile applications use

    Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Chinedu Wilfred Okonkwo --- , South Africa Magda Huisman --- , South Africa Estelle Taylor --- , South Africa
    The development, adoption, and use of mobile applications (mobile apps) in Africa are growing rapidly. Some of these mobile apps have gained widespread acceptance, while others have not due to discontinued use and absolute rejection. This study aims to investigate...
