In this paper a novel all-optical logic NAND, NOR and XOR gate based on nonlinear directional coupler theory is demonstrated. We use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. In other words, while a beam with 4 W/μm in power considered as logical one, the output is NAND gate and if a beam w...

We study gate capacitance of deep submicron MOSFETs with high-K gate dielectrics. Schrödinger’s equation is solved by applying an open boundary condition at silicon-gate dielectric interface. Self-consistent numerical results reveal that accounting for wave function penetration into the gate dielectric causes the carrier distribution to be shifted closer to the gate dielectric. This effect incr...

We demonstrate the advantages of dual-gate polysilicon nanoribbon biosensors with a comprehensive evaluation of different measurement schemes for pH and protein sensing. In particular, we compare the detection of voltage and current changes when top- and bottom-gate bias is applied. Measurements of pH show that a large voltage shift of 491 mV pH(-1) is obtained in the subthreshold region when t...

This paper considers a discrete-time queue with a gate. The system has a single server and a gate. Customers arrive to the system according to a batch Bernoulli process and wait for the next gate opening in front of the gate. When the gate opens, all the customers who are waiting at the gate move into the inside of the gate. The server serves the customers only inside the gate. The gate closes ...

In recent research, we proposed a general framework of quantum-inspired multi-objective evolutionary algorithms(QMOEA) and gave one of its sufficient convergence conditions to Pareto optimal set. In this paper, two Q-gate operators, H2 gate and R&N2 gate, are experimentally validated as two Q-gate paradigms meeting to the convergence condition. The former is a modified rotation gate, and the la...
