## Abstract An optimal universal cloning transformation is derived that produces __M__ copies of an unknown qubit from a pair of orthogonal qubits. For __M__>6, the corresponding cloning fidelity is higher than that of the optimal copying of a pair of identical qubits.
## Abstract Joint stiffness is a major manifestation of joint disease. Nevertheless, an extensive review of the literature reveals that little has been done to characterize joint stiffness quantitatively or qualitatively. A method is described whereby joint stiffness can be measured in precise phys
