Odometry is widely used to localize wheeled and tracked vehicles because of its simplicity and continuity. Odometric calculations integrate the wheel or track’s rotation speed. The accuracy of position thus calculated, is affected by slippage between the ground and the wheel or track. When traveling on a loose slope, the localization accuracy of the odometry decreases remarkably due to slippage...

RNA polymerase II transcription complexes stalled shortly after initiation over a repetitive segment of the template can undergo efficient transcript slippage, during which the 3' end of the RNA slides upstream and then re-pairs with the template, allowing transcription to continue. In the present study, we have used transcript slippage as an assay to identify possible structural transitions th...

Microsatellite markers are widely used for genetic studies, but the relationship between microsatellite slippage mutation rate and the number of repeat units remains unclear. In this study, microsatellite distributions in the human genome are collected from public sequence databases. We observe that there is a threshold size for slippage mutations. We consider a model of microsatellite mutation...

With the widespread use of wheeled mobile robots (WMR) in various applications, new challenges have arisen in terms of designing its control system. One of such challenges is caused by wheel slippage. This paper proposes a new method for haptic teleoperation control of a WMR with longitudinal slippage (not including sliding). In this teleoperation system, the mobile robot’s linear velocity foll...

BACKGROUND The increase in anterior laxity and slippage is greater with metal interference screw fixation of a hamstring anterior cruciate ligament (ACL) graft than a bone-patellar tendon-bone graft. HYPOTHESIS When slippage-resistant fixation is used with a soft tissue graft, early recovery of function does not result in a clinically important increase in anterior laxity and slippage STUDY...

When the spindle assembly checkpoint (SAC) cannot be satisfied, cells exit mitosis via mitotic slippage. In microtubule (MT) poisons, slippage requires cyclin B proteolysis, and it appears to be accelerated in drug concentrations that allow some MT assembly. To determine if MTs accelerate slippage, we followed mitosis in human RPE-1 cells exposed to various spindle poisons. At 37 degrees C, the...

The dynamics of microsatellite, or short tandem repeats (STRs), is well documented for long, polymorphic loci, but much less is known for shorter ones. For example, the issue of a minimum threshold length for DNA slippage remains contentious. Model-fitting methods have generally concluded that slippage only occurs over a threshold length of about eight nucleotides, in contradiction with some di...

Spondylolysis is a stress fracture of the pars interarticularis, which in some cases progresses to spondylolisthesis (forward slippage of the vertebral body). This slip progression is prevalent in children and occurs very rarely after spinal maturation. The pathomechanism and predilection for children remains controversial despite considerable clinical and basic research into the disorder over ...
