It results from "screening" and "antiscreening."
Solutions of the one-loop beta-function when n-sub-f is less than or equal to sixteen predict this behavior, the discovery of which helped to resolve the problem of Landau poles. The fact that magnetic impurities cause electrons to scatter means that this phenomenon characterizes the behavior of resistance at lower temperatures in the (**) Kondo effect. It results from "screening" and "antiscreening." This phenomenon, along with the phenomenon that mandates that no quarks may be found alone, is a result of the fact that the (*) strong force acts upon the particles that mediate it.  For 10 points, name this behavior that earned fame for Politzer, Wilczek, and Gross, which along with color confinement is a characteristic of the strong force in QCD, and which states that quark interactions are weak at shorter distances.
