Webp Li.e L0is polynomial-time Karp-reducible to L. Note that, the poly-time reduction in the de nition can also be replaced with implicit logspace reduction, in that case we would be considering the question whether BPP = L. Thus, we would like to come up with a language L2BPP, such that for every other language L02BPP, WebMar 31, 2024 · Significant variations of ε'r have been found dependingon on t, D and σ. A decrease in the rate of return deformation during irradiation of the material is associated with the frictional properties between macromolecules and a change in the structure, which leads to a weaker straightening of the polymer and their poor sliding.
