Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

Picture this: you’re pushing a boulder down a hill, and suddenly it starts rolling faster on its own, picking up rocks along ...

The increase of time delay due to the limited communication bandwidth usually induces data dropout to make NCS design even more difficult. In this paper, the scheme of the perfect delay compensation ...

Optimal control provides a systematic approach to control robots. However, computing optimal controllers for hardware-in-the-loop control is sensitively affected by modeling assumptions, ...

For each, we describe the relevant feedback mechanisms, examples, and policy implications. Decision makers that understand and harness these dynamics will be at an advantage in accelerating clean ...

GitHub is where people build software. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects.

That feedback loop is now core to product evolution. "We learned to design backward — not from our assumptions, but from how users use the product," said the founder.

In football, defense keeps the opposing team in check. A similar strategy is at play inside our cells. Negative feedback loops (NFLs) help regulate how cells respond to signals, for example ...
