Oscillatory and anti-oscillatory motifs in genetic regulatory networks

Recently,self-sustained oscillatory genetic regulatory networks(GRNs) have attracted significant attention in the biological field.Given a GRN,it is important to anticipate whether the network could generate oscillation with proper parameters,and what the key ingredients for the oscillation are.In this paper the ranges of some function-related parameters which are favorable to sustained oscillations are considered.In particular,some oscillatory motifs appearing with high-frequency in most of the oscillatory GRNs are observed.Moreover,there are some anti-oscillatory motifs which have a strong oscillation repressing effect.Some conclusions analyzing these motif effects and constructing oscillatory GRNs are provided.     

Estimation of key rate after setting dead time

The estimation of key rate is an important aspect of the quantum key distribution process,especially in the use of dead time.In this paper,we demonstrate a numerical simulation to estimate the average detection probability and the key rate.Using our method,the estimated average detection probability is better than the previous result.Besides,we can easily find the best dead time,especially when considering the impact of after pulse.
