A modified Post Widder operators preserving eᴬˣ [PDF]
, 2022 In the present paper, we discuss the approximation properties of modified Post-Widder operators, which preserve the test function eᴬˣ. We establish weighted approximation and a direct quantitative estimate for the modified operators.

Infant Mental Health Journal: Infancy and Early Childhood, Volume 44, Issue 2, Page 200-217, March 2023., 2023 Abstract Parenting interventions can improve parenting outcomes, with widespread implications for children's developmental trajectories. Relational savoring (RS) is a brief attachment‐based intervention with high potential for dissemination. Here we examine data from a recent intervention trial in order to isolate the mechanisms by which savoring ...

Comparative study on Fractional Isothermal Chemical Model
Alexandria Engineering Journal, 2021 This article investigates a family of approximate solutions for the fractional isothermal chemical (FIC) equation based on mass action kinetics for autocatalytic feedback, involving the conversion of a reactant in the Liouville-Caputo sense. We apply two

Sigmoid functions for the smooth approximation to the absolute value function
Moroccan Journal of Pure and Applied Analysis, 2021 We present smooth approximations to the absolute value function |x| using sigmoid functions. In particular, x erf(x/μ) is proved to be a better smooth approximation for |x| than x tanh(x/μ) and x2+μ\sqrt {{x^2} + \mu } with respect to accuracy.

New fractional derivative with non-singular kernel for deriving Legendre spectral collocation method
Alexandria Engineering Journal, 2020 Fractional derivative models with an Abdon-Baleanu-Caputo (ABC) fractional derivative with a non-singular Mittag-Leffler kernel in the Liouville-Caputo (LC) sense are investigated using a spectral collocation method based on Legendre approximations. This

Stability results for approximation by positive definite functions on compact groups [PDF]
, 2008 We consider interpolation methods defined by positive definite functions on a compact group. Estimates for the smallest and largest eigenvalue of the interpola- tion matrix in terms of the localization of the positive definite function on G are ...

Infant Mental Health Journal: Infancy and Early Childhood, Volume 40, Issue 5, Page 640-658, September/October 2019., 2019 ABSTRACT Latina immigrant women are vulnerable to traumatic stress and sexual health disparities. Without autonomy over their reproductive health and related decision‐making, reproductive justice is elusive. We analyzed behavioral health data from 175 Latina immigrant participants (M age = 35; range = 18–64) of the International Latino Research ...
