The value q/p = 1, which corresponds to equal strength of inter and intra-community connections, yields complete random network.
Spectral analysis of deformed random networks
Fig. 1(c) shows the connection matrix for q = 0.005; for this value of q , the inter-community strength is 50% (q/p = 0.5) of the intra- community strength.
Spectral analysis of deformed random networks
For q = 0.005 (q/p = 0.5) (see Fig. 1), where the strength of inter-community is as large as ∼ 50% of the intra-community connections strength, the ∆3 statistics correctly reflects the deviation from complete random matrices, suggesting the existence of communities in the network.

There is also a significant component of intra-cluster stars of up to 50% which lies at the upper end of the observational estimates (see e.g.
Simulations of AGN feedback in galaxy clusters and groups: impact on gas fractions and the Lx-T scaling relation
Including the sequence in stacking interactions W is necessarily more difficult than for the intra-pair potential V because while V can only have two forms, for the AT and GC pairs, there are many more possibilities for the stacking interactions.
Experimental and theoretical studies of sequence effects on the fluctuation and melting of short DNA molecules
The value δ = 0.8 was chosen because it leads to a drop the factor exp(−δy ), to 1 5 of its original value for a stretching y ≈ 2 ˚A of a base pair, corresponding to overcoming the barrier in the intra-pair potential V .
Experimental and theoretical studies of sequence effects on the fluctuation and melting of short DNA molecules
The intra-pair potential is inspired from the results fitted for the PBD model , but, as explained above the relative difference between AT and GC pairs has been reduced.
Experimental and theoretical studies of sequence effects on the fluctuation and melting of short DNA molecules
Adding a barrier for closing to the intra-pair potential V is essential to get correct time scales for the lifetime of the open states.
Experimental and theoretical studies of sequence effects on the fluctuation and melting of short DNA molecules
The second evolution of the model was to introduce the sequence in the stacking interactions because these ineractions depend even more drastically from the sequence than the intra-base potential.
