Potential liability of reproductive endocrinologists for high order multiple gestation

Improving the treatment of infertility: towards avoiding high order multiple gestation.

Sonographic cervical volumetry in higher order multiple gestation.

OBJECTIVE The aim of this study of multifetal pregnancies was the comparison of three-dimensional (3D) volumetry of the cervix, conventional sonographic cervical length measurement and clinical assessment. METHODS 10 mothers were investigated in an observational study between 5/1999 and 9/2000. A total of 34 consecutive 2D- and 3D-transabdominal ultrasound measurements were performed. RESUL...

High-order nonlinear solver for multiple roots

A method of order four for finding multiple zeros of nonlinear functions is developed. The method is based on Jarratt’s 4 fifth-order method (for simple roots) and it requires one evaluation of the function and three evaluations of the derivative. The 5 informational efficiency of the method is the same as previously developed schemes of lower order. For the special case of double 6 root, we fo...
