    • 31 This prediction is based on Eq. (1) using the parameters extracted from NL measurements and assuming P det depends on V 3 T in the same manner as P inj (P inj = P det = TSP). While both P inj and P det drop with increasing bias in the 3T configuration, only P inj drops with increasing bias in the NL configuration. Hence, the calculated 3T signal drops more rapidly than the NL one

    • 32 As discussed in Ref. [18], the full cancellation of drift and diffusion terms, responsible for the suppression of the signal for I inj < 0, occurs only for perfect one-dimensional geometry. This is not necessarily true for two- and three-dimensional geometries, what can lead to a sign reversal
