We demonstrate all 16 two-input logic functions in transiently transfected mammalian cells using only combinations of NOR gates. The same gates were used to construct a three-input circuit ...

NOR, XOR and XNOR). Electronic gates operate on two nominal voltages, normally 0 V and 5 V, representing the logic 0 and the logic 1, respectively. The AND gate has two inputs A and B.

Our logic gates built from de novo designed proteins ... "The whole Apollo 11 Guidance Computer was built from electronic NOR gates," said lead author Zibo Chen, a recent UW graduate student.

The experiment, described today in Nature Communications, turned the cells’ genetic code into NOR logic gates suitable for biologically based circuitry. In digital circuitry that deals with ones ...

According to the team, the new NOR gate can be used to create any types of logic elements necessary for optical chips to perform calculations without the participation of electric current.

These rules determine whether or not the nonlinear output signal is generated. Using this approach, the researchers were able to make ultrafast (less than 100 fs operating time) all-optical XNOR, NOR, ...

The family is available in nine different logic gates: NAND and AND, NOR, OR and XOR, and several buffer functions. To increase application flexibility and further boost performance, the company ...
