A dynamic welding sweater musculoskeletal model of the elbow joint in which muscle, ligament, and articular surface contact forces are predicted concurrently would be an ideal tool for patient-specific preoperative planning, computer-aided surgery, and rehabilitation.Existing musculoskeletal elbow joint models have limited clinical applicability be
Ceramic articular surfaces are now widely used as total hip replacements for young and active patients.However, while the excellent tribological properties and high biocompatibility of ceramic articular surfaces prevent loosening and osteolysis, their high stiffness and low ductility occasionally result in ceramic surface fractures.Therefore, this
Abstract Background Feature selection and prediction are the most important tasks for big data mining.The common strategies for feature selection in big data mining are L 1, SCAD and MC+.However, none of the existing algorithms optimizes L 0, which penalizes the number of nonzero features directly.Results In this paper, we develop a novel sparse ge
