unusual facts about negative feedback



Circumventricular organs

For example, it is thought that the OVLT may also play a role in the regulation of LH secretion via a negative feedback mechanism.

Perceptual control theory

Perceptual control theory (PCT) is a model of behavior based on the principles of negative feedback, but differing in important respects from engineering control theory developed by William T. Powers.

S7G reactor

As with all small pressurized water reactors, the design also had the advantage of negative feedback: an increase in reactor power caused the water to expand, leading to reduced thermalization of neutrons and lowering absorption by the fuel, therefore lowering the power.

HPV-positive oropharyngeal cancer

The biology of HPV+ OPC is distinct of HPV- OPC with P53 degradation (inactivated by E6 instead of by genetic mutation), pRB pathway inactivation (by E7 instead of Cyclin D1 amplification), and P16 upregulation (over-expression of p16 instead of inactivation due to reduced negative feedback from pRB).

Nu Dimension

In week 9, they collaborate with Mulan Jameela sing "Cinta Mati III" and received a negative feedback by the judges and said that they just sounds like a 'backing vocalists'.

Runaway climate change

An example of a negative feedback is that radiation leaving the Earth increases in proportion to the fourth power of temperature, in accordance with the Stefan-Boltzmann law.

Sedimentary budget

When a beach environment is effected by wind, wave and tidal energy it responds with either positive or negative feedback which determines whether the system is balanced and in equilibrium.

Tilted Arc

Commissioned in 1979, Tilted Arc immediately attracted both intense negative feedback, prominently from Chief Judge Edward D. Re, as well as fierce defenders.

Yacovelli v. Moeser

The then Chancellor of UNC, James Moeser, began to appear in various news outlets reporting some of the negative feedback his office had received but supporting the program noting most of the incoming students were assumed to be Christian or Jewish with a comparative lack of understanding Islam and that part of the mission of the university, its "great function", was to help expand understanding of other cultures.
