Powered Prosthesis Locomotion on Varying Terrains: Model-Dependent Control with Real-Time Force Sensing [PDF]
RA-L 7(2):5151-5158, 2022, 2021 Lower-limb prosthesis wearers are more prone to falling than non-amputees. Powered prostheses can reduce this instability of passive prostheses. While shown to be more stable in practice, powered prostheses generally use model-independent control methods that lack formal guarantees of stability and rely on heuristic tuning.

Modes of failure of Trifecta aortic valve prosthesis
Interactive CardioVascular and Thoracic Surgery, 2022 Abstract OBJECTIVES Several concerns have been recently raised regarding the durability of Trifecta prostheses. Different mechanisms of early failure were reported. Our aim was to study in a large population the modes of failure of Trifecta valves.

Catastrophic failure of a monolithic zirconia prosthesis
The Journal of Prosthetic Dentistry, 2015 Recently, monolithic zirconia restorations have received attention as an alternative to zirconia veneered with feldspathic porcelain to eliminate chipping failures of veneer ceramics. In this clinical report, a patient with mandibular edentulism received 4 dental implants in the interforaminal area, and a screw-retained monolithic zirconia prosthesis ...
