A note on polyexponential and unipoly Bernoulli polynomials of the second kind

open access: yesOpen Mathematics, 2021
In this paper, the authors study the poly-Bernoulli numbers of the second kind, which are defined by using polyexponential functions introduced by Kims. Also by using unipoly function, we study the unipoly Bernoulli numbers of the second kind, which are ...

On the solution of (n+1)-dimensional fractional M-Burgers equation

open access: yesAlexandria Engineering Journal, 2021
In the paper, (n+1)-dimensional fractional M-Burgers equation with a force term in the sense of the Caputo fractional derivative is considered. We solve this equation using homotopy perturbation method (HPM) and find its approximate analytical solution ...

Relative effects of breastfeeding intention and practice on maternal responsiveness

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 41, Issue 1, Page 82-93, January/February 2020., 2020
ABSTRACT Our objective was to examine the differential effects of antenatal breastfeeding intention (BI) and breastfeeding practice (BP) on maternal postnatal responsiveness. We conducted a secondary analysis of longitudinal data from a subsample of 962 mother–infant dyads from a U.K.‐based birth cohort study the Avon Longitudinal Study of Parents and ...
