Abstract: A method, apparatus, system, and computer program product for generating information for modifying a model. Training data comprising entities, operations for the entities, and a number of mesh quality metrics for meshes generated from modified entities resulting from the operations being performed on the entities are selected by a computer system. A set of machine learning models is trained by the computer system using the training data. The set of machine learning models trained with the training data identifies a number of mesh quality metrics for a set of input entities in a model input into the set of machine learning models.

Abstract: A flow chamber assembly for subjecting cells or other biological reagents to laminar flow conditions and methods of using the flow chamber assembly are provided herein. The flow chamber assembly includes a bottom plate having at least one well with a bottom surface adapted to receive the cells or biological reagents, a top plate having at least one flow protrusion positioned and shaped to fit into the well of the bottom plate and a sealing element positioned between the top plate and the bottom plate when the top plate and the bottom plate are attached. The flow chamber assembly is configured to allow for laminar flow of a perfusate across the cells or biological reagents along the bottom surface of the well of the bottom plate. The cells or biological reagents can be exposed to a predetermined level of shear stress.

Abstract: A computational model of the internal human pelvic environment. The model comprises meshed finite element regions corresponding to internal tissues or organs selected from the group consisting of pelvic muscles, vagina, vaginal walls, intestinal tissues, bowel tissues, bladder, bladder walls, cervix, and combinations thereof.

Abstract: A ring spring for use in a roller bearing assembly includes one or more inner rings and an outer ring operatively connected to the inner rings. Axial compression of the inner rings displaces the outer ring radially to secure bearings in the roller bearing assembly.

Abstract: Computer software for and a method of generating a conformal all quadrilateral or hexahedral mesh comprising selecting an object with unmeshed boundaries and performing the following while unmeshed voids are larger than twice a desired element size and unrecognizable as either a midpoint subdividable or pave-and-sweepable polyhedra: selecting a front to advance; based on sizes of fronts and angles with adjacent fronts, determining which adjacent fronts should be advanced with the selected front; advancing the fronts; detecting proximities with other nearby fronts; resolving any found proximities; forming quadrilaterals or unconstrained columns of hexahedra where two layers cross; and establishing hexahedral elements where three layers cross.

Abstract: A polymeric, surgical clip having first and second curved legs joined at their proximal ends by a flexible hinge section and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces. The first leg terminates at its distal end in a female locking member comprising a resilient inwardly turned hook having a recess in the mouth of the hook, and the second leg member terminates in a male locking member complimentary to the female locking member and comprising a detent such that when the first and second leg members are moved from an open position to a closed position about the hinge section the hook member will deflect about the distal end of the second leg member thereby engulfing the male locking member in the mouth of the hook and matingly engaging the detent in the recess thereof, thus securely locking the clip in the closed position. The locking feature provides greater closure security to the clip when clamping large diameter or uncompressible tissue.
