—This paper presents the design and fabrication of Single-Port lapaRoscopy bImaNual roboT (SPRINT), a novel tele-operated robotic system for minimally invasive surgery. SPRINT, specifically designed for single-port laparoscopy, is a high-dexterity miniature robot, able to reproduce the movement of the hands of the surgeon, who controls the system through a(More)
A new class of asymptotically nonparametric two-sample approximate tests for discrete interval-censored data is proposed. This class extends the family developed by Pepe and Fleming (1989, Biometrics 45, 497-507) for right-censored data and is based on an integrated weighted difference in survival function estimates. The tests are sensitive to the(More)
Fig. 1. Achitecture of the STIFF-FLOP arm and dimensions of a single module. On the left inset section of the single module, on the right inset cross section of the module. Abstract— This paper presents the design of a single module composing a modular soft variable stiffness manipulator for minimal access surgery. The module exploits flexible fluidic(More)
We consider methods for selecting the joint specification of the mean and variance functions in statistical models for rates or counts. Based on analyses of diagnosis-specific hospital discharge rates in Michigan, we show that a Poisson model with an extra variance component for the systematic variation is superior to several other probability models with(More)
