From 1940 through the 1960s, diethylstilbestrol (DES), a synthetic oestrogen, was given to pregnant women to prevent pregnancy complications and losses. Subsequent studies showed increased risks of reproductive tract abnormalities, particularly vaginal adenocarcinoma, in exposed daughters. An increased risk of breast cancer in the DES-exposed mothers was(More)
Of 207 patients with acute bacterial meningitis previously reported by Dodge and Swartz, seizures occurred in 56 (27%). Most seizures began on the first or second day, and most stopped within two days. Seizures occurred most often at the extremes of life. Age-adjusted seizure frequency was greater with Hemophilus influenzae meningitis than with(More)
OBJECTIVE To determine whether infants at sleep in the prone side positions are at higher risk for an extreme cardiorespiratory event compared with infants at sleep in the supine position. STUDY DESIGN We used a case-control study to compare sleep position, determined with an accelerometer, in 116 infants during an extreme cardiorespiratory event with(More)
Numerical analysis is concerned with the accurate and eecient evaluation of mathematical expressions, especially on computers with oating point arithmetic. While scientists have always been concerned to some extent with numerical computation, the modern discipline of numerical analysis is almost entirely a product of the period since 1950 during which there(More)
Polynomials are very simple mathematical functions which have the flexibility to represent very general nonlinear relationships. Approximation of more complicated functions by polynomials is a basic building block for many numerical techniques. This article considers two distinct but related applications. The first is polynomial regression in which(More)
