11. Note that under open boundary conditions, the finite-size effects appear in the opposite way that larger systems are less resistive. See, M. Y. Choi, G. S. Jeon, and M. Yoon, Phys. Rev. B 62, 5357 (2000).
12. This is in parallel to the static Monte Carlo results where opposite size dependences have been observed under different boundary conditions. See, e.g., P. Olsson, Phys. Rev. Lett. 73, 3339 (1994).

14. According to Ref. 9, consideration of the finite penetration depth, about 15 lattice spacings in the array in Ref. 4, results in small enhancement of the barrier height; this does not alter the conclusion of this paper.
