Breast cancer incidence rates in the United States are substantially lower among Asian-American women than among White or African-American women. The authors determined whether mammographic density reflects these ethnic differences by evaluating mammograms from 442 White, African-American, and Asian-American women without breast cancer who served as controls in one of two population-based, brea...

The prevalence of breast augmentation and breast lift surgery suggests that many women are dissatisfied with their breasts. This study analyzed women’s and men’s views about breast size and shape among 52,227 heterosexual adults, ages 18–65, who responded to an online survey.

This paper presents and discusses a fault-tolerant control model on a autonomous underwater vehicle (AUV) with six thrusters, using five degrees of freedom. Simulations were made when there are no faults and when faults occur in two of the horizontal thrusters. The kinematics and dynamics of the vehicle and the thrusters are explained and it is given an introduction of automatons and how they w...
