Cocaine and alcohol abusers, for example, are known to produce far less dopamine in their brains than people who aren't addicted to those drugs.
As an example, if a modem is known to produce an error that is proportional to the measured distance, then one would penalise the weighting for a larger distance measurements.
For example, bird tails are known to produce lift during flight [1], [2].
For example, only 50% of invasive meningococcal isolates are known to produce NadA, present in 4CMenB, in detectable quantities (NadA expression is phase variable) with a significant proportion of the NadA negative isolates not having the NadA gene at all.
For example, while no present day Epichloë typhina isolates are known to produce lolines, our data support the hypothesis that the E. typhina ancestor(s) of three asexual endophyte species contained a LOL gene cluster.
For example, interspecies crosses between pairs of these three species are known to produce several distinct experimental models for induction and progression of melanoma [ 5, 6].
Separate species have been known to produce hybrid offspring (for example, the horse and the donkey producing the mule), but, because the offspring are almost always inviable or sterile, the interbreeding is not considered successful.
General Electric, for example, is known as much for producing leaders as it is for airplane engines or light bulbs.
The guaraná berry, for example, is known as a stimulant.
Yes, multi-touch (for example) was known about for years.
