On the other hand, for samples with strip-and disk-shaped surface potential inhomogeneities, we have obtained quantitative expressions for the detectability size requirements as a function of experimental conditions for both AM-and FM-EFMs, which suggest that a larger tip radius of curvature is moderately favored for detecting the presence of such inhomogeneities. In this section, we analyze the short-term loss avoidance of every unplanned, open-market insider sale made by Fritz Prinz in QS / Quantumscape Corp. A consistent pattern of loss avoidance may suggest that future sale transactions may predict declines in price.
