What can the systems theory distinction between positive and negative feedback tell us about how recovery succeeds?

This paper extends the robust feedback stability theorem of negative imaginary systems by removing restrictive assumptions on the instantaneous gains of the systems that were imposed in the earlier ...

Growth‐rate dependent sensitivity of E. coli to the antibiotic trimethoprim leads to a negative feedback loop that explains the extreme shallowness of the dose‐response curve. This feedback loop is ...

A negative feedback loop is a mechanism to help regulate human health by ensuring that a biological reaction is appropriate and that the systems of the body are in a constant state of equilibrium, ...

A downstream negative feedback directly regulates the LED brightness without changing the input." Tate sees the work as a key step in understanding how immune systems balance cost and control.

In mechanical and electrical systems, feedback can be used to improve a system’s robustness against disturbances. (11) For example, negative feedback in electronic circuits can improve robustness for ...

The true function of our endocannabinoid system has been obscured by its name. It has no essential relationship to cannabis but is instead a master regulator of brain chemistry.

Abstract A study was conducted on the effect of time delay and structural parameters on the vibration reduction of a time delayed coupled negative stiffness dynamic absorber in nonlinear vibration ...

In this article, we present necessary and sufficient conditions under which a linear time-invariant (LTI) system is state feedback equivalent to a negative imaginary (NI) system. More precisely, we ...
