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 ...

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 ...

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 ...

The NOT function in Microsoft Excel is a built-in Logical function that reverses the logic of its argument. It ensures that one value is not equal to another. When given TRUE, NOT returns FALSE. When ...

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 ...

Living substrates are capable for nontrivial mappings of electrical signals due to the substrate nonlinear electrical characteristics. This property can be used to realise Boolean functions. Input ...

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 ...

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

How can cells be programmed to respond to complex signals and make targeted decisions, similar to a logical circuit in a computer? An interdisciplinary team from two research groups at the Centre for ...
