The optoelectronic logic element AND, OR and XOR is considered, the output signal of which can be inverted when the input control signal is applied, thereby converting the logic element into NAND, NOR ...

Including XOR gates in your functions offers significant benefits by reducing transistor and track counts and increasing testability. As designers, we're used to representing digital functions using ...

The idea of making DNA perform computational tricks is hardly new. These data-packed molecules are in many ways perfect for the job. One very public test of their potential came in 1994, when Leonard ...
