runaway effect

runaway effect

[′rən·ə‚wā i‚fekt]
(electronics)
The phenomenon whereby an increase in temperature causes an increase in a collector-terminal current in a transistor, which in turn results in a higher temperature and, ultimately, failure of the transistor; the effect limits the power output of the transistor.
(plasma physics)
The phenomenon whereby an electric current in a plasma produces heat through the Joule effect, and the resulting temperature increase results in an increase in conductivity and, thereby, an increase in current flow.

We need studies to show when they might cause a runaway effect.
Key features to understand why a positive feedback does not necessarily lead to a runaway effect are described.
Otherwise known as exponential technology, it is a theory that the speed of technological development will cause a runaway effect such that artificial intelligence will outpace human intellectual capacity and control.
It's not a runaway effect where everything is killed.
For example, both Earth and Venus experience an atmospheric "greenhouse effect" -- but the runaway effect on Venus makes it the hottest place in the solar system.
One of the main researchers, Dr Mark Swinbank, said: "The runaway effect in this galaxy suggests it is growing much faster than expected.

There aren't any loping ballads or amble-through-the-park ditties to offset the careening, runaway effect. Schneider uses the pace to brace his open-ended, unresolved vignettes like "Do You Understand?", which at first draws a suicidal revolutionary which in turn morphs into a rejected lover.
"According to the core accretion model, as the original planetary nebula cooled, planetesimals collided and stuck together in a runaway effect that formed planet cores," Militzer said.
