1.   A standard improvement on this feedback loop is shown next.

2.   Ashby was an engineer interested in nonlinear control circuits and the virtues of positive feedback loops.

3.   Deviancy amplification is achieved by means of a relatively simple positive feedback loop.

4.   For that, one needs some kind of feedback loop.

5.   Fortunately, feedback loops can be combined into useful configurations.

6.   The loss was caused by technological change and the amplifying feedback loop of responses to that change.

7.   This seems to be what is happening in the examples above, where the adult is acting as a simple feedback loop.

8.   A feedback loop is the central means of control and timely, systematic measurement is the chief means of providing useful feedback.

9.   Recent work has focused on the gastrin acid secretion feedback loop and identified a number of potential pathogenetic pathways.
