On a class of embedded cubature formulae on the simplex
ACI Avances en Ciencias e Ingenierías, 2014 In this paper we investigate a class of embedded cubature formulae on the simplex announced in [1]. Here we recall the class of formulae, we introduce the remainder and we give an estimation of this, we also investigate the convergence.

Infant Mental Health Journal: Infancy and Early Childhood, Volume 42, Issue 3, Page 423-437, May/June 2021., 2021 ABSTRACT A previous randomized controlled trial has suggested the effectiveness of a Dutch postdischarge responsive parenting program for very preterm (VPT) infants, indicating that nationwide implementation was justified. This paper describes the development and nationwide implementation of the intervention, known as the TOP program, which consisted ...

Infant Mental Health Journal: Infancy and Early Childhood, Volume 42, Issue 1, Page 21-34, January/February 2021., 2021 ABSTRACT Parental reflective functioning (PRF) is an important predictor of infant attachment, and interventions that target parent–infant/toddler dyads who are experiencing significant problems have the potential to improve PRF. A range of dyadic interventions have been developed over the past two decades, some of which explicitly target PRF as part ...

About a dubious proof of a correct result about closed Newton Cotes error formulas
Open Mathematics, 2023 In this study, we comment about a wrong proof, at least incomplete, of the closed Newton Cotes error formulas for integration in a closed interval [a,b].\left[a,b].

Some new inequalities for means of two arguments
International Journal of Mathematics and Mathematical Sciences, Volume 25, Issue 8, Page 525-532, 2001., 2001 We prove certain new inequalities for special means of two arguments, including the identric, arithmetic, and geometric means.

Numerical methods of computation of singular and hypersingular integrals
International Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 3, Page 127-179, 2001., 2001 In solving numerous problems in mathematics, mechanics, physics, and technology one is faced with necessity of calculating different singular integrals. In analytical form calculation of singular integrals is possible only in unusual cases. Therefore approximate methods of singular integrals calculation are an active developing direction of computing ...

Two-Point Quadrature Rules for Riemann–Stieltjes Integrals with Lp–error estimates
Moroccan Journal of Pure and Applied Analysis, 2018 In this work, we construct a new general two-point quadrature rules for the Riemann–Stieltjes integral ∫abf(t) du (t)$\int_a^b {f(t)} \,du\,(t)$, where the integrand f is assumed to be satisfied with the Hölder condition on [a, b] and the integrator u is
