bstract Purpose: The majority of births to young women are unintended (either mistimed or unwanted), bearing an increased risk of poor health outcomes for both mother and child. In this analysis, we describe trends of unwanted, mistimed, and intended births reported by all women and specifically by young women in the National Survey of Family Growth (NSFG). Methods: Using data from the 1982, 19...

This paper is primarily concerned with a special case of one of the leading problems of mathematical logic, the problem of finding a regular procedure to determine the truth or falsity of any given logical formula*. But in the course of this investigation it is necessary to use certain theorems on combinations which have an independent interest and are most conveniently set out by themselves be...

A finite chain calculation in terms of Hubbard X-operators is explored by setting up a vibronic Harniltonian. The model conveniently transformed into a form so that in the case of strong coupling a numerical renormalization group approach is applicable. To test the technique, a one particle Green function is calculated for the model Harniltonian
