    • Uniform sparse bounds for discrete quadratic phase Hilbert transforms 

      Kesler, Robert; Mena Arias, Darío Alberto (2017-09)
      Consider the discrete quadratic phase Hilbert Transform acting on $\ell^{2}(\mathbb{Z})$ finitely supported functions $$ H^{\alpha} f(n) : = \sum_{m \neq 0} \frac{e^{i\alpha m^2} f(n - m)}{m}. $$ We prove that, ...
    • Using generalized logistics regression to forecast population infected by Covid-19 

      Villalobos Arias, Mario Alberto (2020-04-05)
      In this work, a proposal to forecast the populations using generalized logistics regression curve fitting is presented. This type of curve is used to study population growth, in this case population of people infected ...
    • Vertical Transmission in a Two-Strain Model of Dengue Fever 

      Murillo, David; Holechek, Susan A.; Murillo, Anarina L.; Sánchez Peña, Fabio Ariel; Castillo Chávez, Carlos (2014)
      The role of vertical transmission in vectors has rarely been addressed in the study of dengue dynamics and control, in part because it was not considered a critical population-level factor. In this paper, we apply the ...
