- This result indicates that negative feedback reduces system noise and enables a robust transition in cell state within a narrow Shh signal concentration range near the deterministically predicted switching point.
- We are able to provide an intuitive understanding of this result, because when the activators are fixed, both models reduce to a single delay differential equation with negative feedback.
- The earliest guitar amps from the Tweed era did not have negative feedback, a simplicity that yielded higher distortion and allowed the speaker to emote more character.
