Complications associated with the ureteral stump after nephrectomies rarely occur, especially after donor nephrectomies. The potential for the slippage of clips is a well-known event associated with vascular ligations. We report on the first case of clip slippage from the ureter and describe diagnosis and management of the most extreme of morbid presentations.

This paper deals with path tracking control of tracked vehicle on extremely soft cohesive soil. The dynamics of tracked vehicle is very complex and nonlinear because of the slippage of vehicle and the soil shearing. For the purpose of control of tracked vehicle we adopted simplified approaches. The vehicle is modeled as single-body vehicle. Two kinds of PD (Proportional-Differential) controller...

Cellular senescence is a tumor suppressor mechanism where cells enter a permanent growth arrest following cellular stress. Oncogene-induced senescence (OIS) is induced in non-malignant cells following the expression of an oncogene or inactivation of a tumor suppressor. Previously, we have shown that protein kinase C iota (PKCι) depletion induces cellular senescence in glioblastoma cells in the ...

Microsatellite lengths change over evolutionary time through a process of replication slippage. A recently proposed model of this process holds that the expansionary tendencies of slippage mutation are balanced by point mutations breaking longer microsatellites into smaller units and that this process gives rise to the observed frequency distributions of uninterrupted microsatellite lengths. We...

Study Design Retrospective review of prospectively collected outcome data. Purpose To compare 5-year outcomes following decompression with fusion (FU) and microendoscopic decompression (MED) in patients with degenerative lumbar spondylolisthesis (DLS) and to define surgical indication limitations regarding the use of MED for this condition. Overview of Literature There have been no comparat...

Mobile robots are increasingly being used in high-risk, rough terrain situations, such as planetary exploration and military applications. Current control and localization algorithms are not well suited to rough terrain, since they generally do not consider the physical characteristics of the vehicle and of its environment. Poor attention has been devoted to the study of the dynamic ill-effects...

A traditional view is that sexual reproduction increases the potential for phenotypic evolution by expanding the range of genetic variation upon which natural selection can act. However, when nonadditive genetic effects and genetic disequilibria underlie a genetic system, genetic slippage (a change in the mean genotypic value contrary to that promoted by selection) in response to sex may occur....

The aim of the study is to develop a design and control system wheeled underwater robot with adjustable buoyancy for under-ice monitoring objects.As part study, task generate mathematical model its computer implementation controlled movement on inner surface ice, as well set up computational experiments demonstrating operability proposed automatic an anti-slip device.The work uses both classica...

We report a quartz crystal microbalance study of the nanodynamical properties of tricresylphosphate (TCP) reaction films formed on high purity Fe, Cr, Fe oxide, and Cr oxide surfaces at elevated temperatures. The data reveal trace levels of interfacial slippage, potentially in conjunction with viscoelastic effects, for reaction films characterized by very low macroscopic friction coefficients. ...
