Throughout this paper we maintain a time delay [defined in Eq. (13)] of Δt = 1014τ. The effect of time delay Δt on reduction of efficiency Vfeedback/Vwithout has been discussed in detail in Ref. 1. In general, the smaller the Δt, the smaller the Vfeedback/Vwithout is. For Δt = 1014τ the reduction efficiency Vfeedback/Vwithout changes only slightly when Δt decreases.
