Multivariable logistic regression analysis was used for statistical analyses. Results: Age of female subjects [35-38 years, odds ratio (OR): 0.39;≥39 years, OR: 0.14], uterine factor subfertility (OR: 5.24), and treatment modalities (ORs: IUI 0.25, IVF 2.33 and ICSI 1.91) significantly predicted a LB outcome (P<0.05). The cumulative live birth rates were 11.7% IUI, 41.5% IVF, 27.5% ICSI and 22.6% from frozen embryo transfer cycles. The cumulative SC rate was 24.6% in the non-treated group and 10.7% in the treated group. All LBs from IVF cycles were delivered by the second cycle and within four years, compared to SC delivery of within five years in the non-treated group and six years in the treated group. Conclusions:Age of female subject, uterine factor and modalities of treatment are significant predictors for LB outcome at the first cycle. Higher delivery rates could be achieved following fewer successive IVF cycles and within a shorter duration compared to SC.展开更多

The mutual impedance matrix is derived from electromagnetic boundary conditions and can be used to relate the coupling free open-circuit voltages, instead of the conventional ones, to the measured voltages. A remarkable improvement on compensation for the coupling effects is shown in the direction finding applications, while a simple relationship between measured terminal voltages and the coupling free voltages is remained.展开更多

Considering the environmental interface as a complex system we elaborated the advanced mathematical tools for its modelling. We have suggested two coupled maps serving the exchange processes on the environmental interfaces spatially ranged from cellular to planetary level, i.e. 1) the map with diffusive coupling for energy exchange simulation and 2) the map with affinity, which is suitable for matter exchange processes at the cellular level. We have performed the dynamical analysis of the coupled maps using the Lyapunov exponent, cross sample as well as the permutation entropy in dependence on different map parameters. Finally, we discussed the map with affinity, which shows some features making it a promising toll in simulation of exchange processes on the environmental interface at the cellular level.展开更多
