BACKGROUND In addition to the conventional methods used to improve leg contours, total leg sculpture, including liposuction, selective neurectomy, and transilluminated powered phlebectomy, provides a one-time solution of leg contour problems, which is a major aesthetic concern among Asian women. The authors present the postoperative results of total leg(More)
OBJECTIVE This article presents a points-based prognostic prediction model for pediatric acquired cholesteatoma, incorporating the multidimensional factors that contribute to surgical failure. METHODS This study included 132 ears with acquired cholesteatoma from 128 children (≤18 years) identified between 1982 and 2012. Each case was scored for the extent(More)
As modern systems are integrating exceeding number of components for better performance and functionality, early full-system simulation tools have become essential for validating complex concurrent system interaction activities. In the past decades, many useful timing-accurate system simulation tools have been developed; however, we find that even for the(More)
A period-doubling route to chaos with nonstationary transverse pattern is observed in a diode-pumped Nd:YAG laser with a Cr(4+):YAG saturable absorber. The nonlinear behavior results from the multitransversemode competition with gradually adding the number of the transverse modes. By analyzing the transverse pattern, we find that the bifurcation accompanies(More)
