A shock-absorbing shoe structure having adjustable elasticity is disclosed. Emission from the at least one inductively stimulated implant is detected and a position of the at least one implant is determined based on the detected emission. In preferred embodiments, the second prosthesis includes a branch leg that may be disposed and anchored in an either a cross artery or a downstream artery to facilitate fluid flow. In another exemplary embodiment, a data record that satisfies the database query is generated in order to increase coverage when testing a database management system. The upper portion of the first leg forms a back plate that is displaced from the plane of the lower portion, with a generally horizontal ledge connecting the upper portion to the lower portion. Upon determining to form the processing result on the original, the image forming apparatus forms the processing result on the original, and upon determining to not form the processing result on the original, the image forming apparatus forms the processing result on a sheet other than the original.
