For the first time, researchers have performed logic operations with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods open up research possibilities ...

Using digital logic gates such as AND, OR, XOR, NOT, NAND, NOR, and XNOR and other related logic functions is often the foundation for defining the relationship between electrical signals and how they ...

Deoxyribonucleic acid is a highly programmable biomolecule because of its precise base-pairing property 1, which makes it possible to construct DNA circuits for complex tasks. To date, DNA circuits ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...

Excel's logical functions test whether a statement or data is true or false, before enabling the program to carry out an action based on the result. They are useful for analyzing data, automating ...

Modern semiconductor-based electronics is rapidly approaching fundamental limits caused by interconnect delays and large heat generation 1. Because photons have intrinsically higher ...

Researchers at Manchester University in the UK have used graphene to make a new electrically-controlled switching device that supports both memory and logic functions. The device, which exploits ...

It’s possible to use an 8:1 multiplexer to implement any 3-input logical function, but can we use it to implement a 4-input function? On the one hand, some logic problems never seem to go away. On the ...
