Recurrence of Preeclampsia in Northern Tanzania: A Registry-based Cohort Study. [PDF]

open access: yes, 2013
Preeclampsia occurs in about 4 per cent of pregnancies worldwide, and may have particularly serious consequences for women in Africa. Studies in western countries have shown that women with preeclampsia in one pregnancy have a substantially increased ...

The mathematics of generalized Fibonacci sequences: Binet's formula and identities [PDF]

open access: yesMathematica Moravica
This article considers a generalized Fibonacci sequence {Vn} with general initial conditions, V0 = a, V1 = b, and a versatile recurrence relation Vn = pVn-1 + qVn-2, where n ≥ 2 and a, b, p and q are any non-zero real numbers. The generating function and

Matrix interpretation of multiple orthogonality [PDF]

open access: yes, 2010
In this work we give an interpretation of a (s(d + 1) + 1)-term recurrence relation in terms of type II multiple orthogonal polynomials.We rewrite this recurrence relation in matrix form and we obtain a three-term recurrence relation for vector ...

On orthogonal polynomials and related discrete integrable systems [PDF]

open access: yes, 2006
Orthogonal polynomials arise in many areas of mathematics and have been the subject of interest by many mathematicians. In recent years this interest has often arisen from outside the orthogonal polynomial community after their connection with ...

Recurrence coefficients for discrete orthonormal polynomials and the Painlevé equations [PDF]

open access: yes, 2013
We investigate semi-classical generalizations of the Charlier and Meixner polynomials, which are discrete orthogonal polynomials that satisfy three-term recurrence relations.

Floor and ceiling functions for Pell numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
The analytical study of the Pell number and the role of floor and ceiling functions into their computation is examined. Closed expressions of Pell numbers were initially derived using Binet's formula, followed by an asymptotic behavior study of the ...

Asymptotic series solution of variational stokes problems in planar domain with crack-like singularity

open access: yesApplied Mathematics in Science and Engineering, 2022
A class of nonlinear variational problems describing incompressible fluids and solids by stationary Stokes equations given in a planar domain with a crack (infinitely thin flat plate in fluids) is considered.

Sigma function solution of the initial value problem for Somos 5 sequences [PDF]

open access: yes, 2007
The Somos 5 sequences are a family of sequences defined by a fifth order bilinear recurrence relation with constant coefficients. For particular choices of coefficients and initial data, integer sequences arise.
