It has been shown that the network growth models constructed on the principle of duplication and divergence can recapture the topo- logical properties of real PPI networks. However, such network models only consider the evolution processes. How to select the model parameters with the real biological experi- mental data has not been presented. Therefore, based on the real PPI network statistical data, a yeast PPI network model is constructed. The simulation results indicate that the topological characteristics of the constructed network model are well consistent with those of real PPI networks, especially on sparseness, scale-free, small-world, hierarchical modularity, and disassortativity.展开更多

Femtosecond laser-assisted small incision lenticule extraction(SMILE) is becoming the new direction in refractive surgery,and the ocular surface changes after SMILE are attracting increasingly more attention. This article reviews adverse effects,including dry eye, injury of corneal nerves, and ocular surface inflammation,.occurring after SMILE.展开更多

Moreover, the monomer reactivity ratios of methyl methacrylate(MMA) and Gd(MAA)3 were evaluated by using Kelen-Tiidos method. The thermal neutron shielding properties of PMMA and poly(MMA-co-Gd(MAA)3) were calculated by MCNP program. The results show that the selfpolymerization of Gd(MAA)3 can be initiated by thermal and free radical and its activation energy is103.35 kJ/mol or 58.55 kJ/mol correspondingly in the solid state or aqueous solution. The polymerization rate,Rp,under low conversion at 65 ℃ is expressed as Rp = K[M]^(1.05)[I]^(0.60). The reactivity ratios of r1(MMA) and r2(Gd(MAA)3) are 0.225 and 1.340, respectively. The ability of thermal neutron shielding of poly(MMA-co-Gd(MAA)3) is increased by gadolinium contents and is far better than PMMA.展开更多
