An object of the present invention is to provide a novel compound which has a potent inhibitory effect on FXa and exhibits an excellent antithrombotic effect when orally administered. A delay element operably coupled into the ring oscillator configuration modifies the predetermined frequency of the ring oscillator configuration. One bits of the identifier may be encoded as unusable ones of the specific sectors and zero bits of the identifier may be encoded as usable one of the specific sectors. The torsion features and interconnects may be independently optimized to provide the interconnect with maximum stiffness and a maximum deflection at same time.
