Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate -- a simple computer -- to better understand what causes specific cells to migrate. Cancer cells ...

A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

Multiplying two analog signals involves the use of analog multipliers, usually implemented by using log and antilog circuit blocks or the Gilbert cell. Today, the most common technique used to ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central processing ...

How well do you know your logic gates? For their final submission for STEM Projects class, [BKriet] gamified the situation using a Raspberry Pi Pico, some blinkenlights, and a not-insignificant amount ...

A long-standing quest for science and technology has been to develop electronics and information processing that operate near the fastest timescales allowed by the laws of nature. A promising way to ...

Cancer cells migrate through the body for multiple reasons; some are simply following the flow of a fluid, while others are actively following specific chemical trails. So how do you determine which ...

If you are reading this on your smartphone, its CPU (central processing unit) is running at its full speed. It is a tiny chip containing billions of the more basic units called logic gates. In the ...
