The force regulation and inevitable positional inaccuracy of traditional control system can be compensated by the compliance/stiffness mechanism. The compliance/stiffness of a robotic mechanism is usually modeled by a 6 by 6 symmetric positive definite matrix at an equilibrium point using screw theory. When an external wrench is exerted on the mechanism and the mechanism moves away from its equ...

The possibility of neutron swapping between the ordinary and mirror sectors is today a subject great many theoretical experimental studies. In this paper, we investigate neutron-mirror transitions in different environments from vacuum to star. Our approach based on density matrix formalism, Lindblad Bloch equations implication seesaw mechanism Hamiltonian diagonalization.
