Background：The SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery Score Ⅱ （SS-Ⅱ） can well predict 4-year mortality in patients with complex coronary artery disease （CAD）,and guide decision-making between coronary artery bypass graft surgery and percutaneous coronary intervention （PCI）.However,there is lack of data regarding the utility of the SS-Ⅱ in patients with three-vessel CAD undergoing PCI treated with second-generation drug-eluting stents （DES）.The purpose of the present study was to evaluate the ability of the SS-Ⅱ to predict long-term mortality in patients with three-vessel CAD undergoing PCI with second-generation ***：Totally,573 consecutive patients with de novo three-vessel CAD who underwent PCI with second-generation DES were retrospectively *** to the tertiles of the SS-Ⅱ,the patients were divided into three groups：The lowest SS-Ⅱ tertile （SS-Ⅱ ≤20）,intermediate SS-Ⅱ tertile （SS-Ⅱ of 21-31）,and the highest SS-Ⅱ tertile （SS-Ⅱ ≥32）.The survival curves of the different groups were estimated by the Kaplan-Meier *** and multivariate Cox proportional hazard regression analyses were performed to evaluate the relationship between the SS-Ⅱ and 5-year *** performance of the SS-Ⅱ with respect to predicting the rate of mortality was studied by calculating the area under the receiver operator characteristic （ROC） *** predictive ability of the SS-Ⅱ for 5-year mortality was evaluated and compared with the SS ***：The overall SS-Ⅱ was 27.6 ± *** patients in the lowest,intermediate and the highest SS-Ⅱ tertiles,the 5-year rates of mortality were 1.6%,3.2%,and 8.6%,respectively （P =0.003）;the cardiac mortality rates were 0.5%,1.9%,and 5.2%,respectively （P =0.014）.By multivariable analysis,adjusting for the potential confounders,the SS-Ⅱ was an independent predictor of 5-year mortality （hazard ratio：2.45,95% confidence interval：1.38-4.36;P=0.002）.The SS-Ⅱ demonstrated a high

Plough pans （PPs）, common in the black-soil region of northeastern China, have significant effects on the root systems of crops. We conducted a field experiment to study the distribution of soybean roots under the influence of PPs. The soybean roots showed compensatory growth above the PP, with higher root length and weight in soil with a PP compared to those without a PP. Roots were heavier and longer in the 15-75 cm soil layer without a PP than with a PP. Soil porosity was lower in the PP and the soil below the PP, which likely decreased the oxygen content of the soil and induced more growth of roots above the PP. The PP is also likely to decrease infiltration of rain-water and hinder the migration of nitrate downward, which in turn increased the density and length of soybean root hairs, which, hence, promoted growth.

Load distribution is the foundation of shape control and gauge control, in which it is necessary to take into account the shape control ability of TCM （tandem cold mill） for strip shape and gauge quality. First, the objective function of generalized shape and gauge decoupling load distribution optimization was established, which considered the rolling force characteristics of the first and last stands in TCM, the relative power, and the TCM shape control ability. Then, IGA （immune genetic algorithm） was used to accomplish this multi-objective load distribution optimization for TCM. After simulation and comparison with the practical load distribution strategy in one tandem cold mill, general- ized shape and gauge decoupling load distribution optimization on the basis of IGA approved good ability of optimizing shape control and gauge control simultaneously.
