The quantum-dot cellular automata (QCA) nano-technique has attracted computer scientists due to its noticeable features such as low power consumption and small size. Many papers have been published in the literature about the utilization of this technology for de-signing many QCA circuits and for presenting logic gates in an optimal structure. The T flip-flop. which is an essential pa... https://www.spidertattooz.com/Air-Force-Embroidered-OCP-Sew-On-Officer-Rank-Insignia-Major/
