Introduction. This paper describes case reports where coronal growth of soft tissue on implant threads was observed after surgery for soft tissue graft. This phenomenon is known as "creeping attachment." Methods. Two patients were submitted to gingival graft procedure including subepithelial connective tissue graft and masticatory mucosal graft. A two-year follow-up appointment was performed. R...

Consider the flow of a thin layer of non-Newtonian fluid over a solid surface. I model the case where the viscosity depends nonlinearly on the shear-rate; power law fluids are an important example, but the analysis here is for general nonlinear dependence. The modelling allows for large changes in film thickness provided the changes occur over a relatively large enough lateral length scale. Mod...

We consider stagnation point flow away from a wall for creeping flow of dilute polymer solutions. For a simplified flow geometry, we explicitly show that a narrow region of strong polymer extension (a birefringent strand) forms downstream of the stagnation point in the UCM model and extensions, like the FENE-P model. These strands are associated with the existence of an essential singularity in...

Creeping featurism is a process that produces complexity. This paper describes ways to prevent or escape from creeping featurism. We discuss limitations of current methods of user interface design and usability engineering, and propose a fitness management strategy to detect feature creep and to aid the search for innovations.

The source of repeating earthquakes on creeping faults is modeled as a weak asperity at a border between much larger locked and creeping patches on the fault plane. The x−1 2 / decrease in stress concentration with distance x from the boundary is shown to lead directly to the observed scaling T M ∝ 0 1 6 / between the average repeat time and average scalar moment for a repeating sequence. The s...
