The class of functions that can be uniformly approximated by weighted polynomials of the form w n P with deg P F n, depends on the behavior of the extremal n n measure associated with w as introduced by Mhaskar and Saff. It is shown that if in a neighborhood of a point t the extremal measure has a d
## Abstract We consider a system of ordinary differential operators of mixed order on an interval (0, __r__~0~), __r__~0~ > 0, where some of the coefficients are singular at 0. A special case has been dealt with by Kako, where the essential spectrum of an operator associated with a linearized magne
Early detection of abnormal development of the fetal skeletal system is only one of the structural abnormalities that have been studied with ul-trasound1-4. In order to evaluate a fetus at risk for a skeletal dysplasia, careful scanning of upper and lower extremities, cranium, thorax and abdomen is
