From the macro-perspective, seven indexes including urban land use, township economic development stage, urbanization and township enterprise structure are selected. From the micro-perspective, 12 indexes including location situation, governance capability and economic developmental level at village level are selected. Besides, the multiple factors evaluation model is established. Taking implementation items of cooperated rural households in Hubin Village, Baijia Town of Dianjiang County as an example, the implantations items are analyzed by using the comprehensive evaluation model and the evaluation results are in accordance with actual situation. The effectiveness of the comprehensive evaluation method is proved. However, affected by the limited application scope of implementation model, insufficient policy and one-sided farmers' participation, in order to avoid copying the successful experience of completed pilot blindly, farmers are suggested to adopt the implementation model of cooperated rural households.展开更多

The mineral elements were analyzed by the Principal Component Analysis and the Factor Analysis on the SPSS 10.0 and three main factors were picked. The results showed that Se, S and Se-S cooperated application enhanced the garlic nutrition quality by increasing mineral nutrition. The garlic Vc was the highest after using higher Se compared middle S level (S 20 mg/kg soil + Se 40 mg/kg soil). Lower Se level compared middle S level (S 40 mg/kg soil + Se 20 mg/kg soil) get the highest garlic abio-Se in all treatments. The garlic organic Se content was the highest after using higher Se compared middle S (S 40 mg/kg soil + Se 40 mg/kg soil). The treatment lower S compared lower Se level get the highest garlic allicin in all treatment. It showed that the fresh eating factor was affected by the element Se. The flavor factor and health care factor were affected by both Se and S.展开更多

However, a critical challenge in accomplishing automated vehicle platoons is to deal with the effects of intermittent and sporadic vehicle-to-vehicle data transmissions caused by limited wireless communication resources. This paper addresses the co-design problem of dynamic event-triggered communication scheduling and cooperative adaptive cruise control for a convoy of automated vehicles with diverse spacing policies. The central aim is to achieve automated vehicle platooning under various gap references with desired platoon stability and spacing performance requirements, while simultaneously improving communication efficiency. Toward this aim, a dynamic event-triggered scheduling mechanism is developed such that the intervehicle data transmissions are scheduled dynamically and efficiently over time. Then, a tractable co-design criterion on the existence of both the admissible event-driven cooperative adaptive cruise control law and the desired scheduling mechanism is derived. Finally, comparative simulation results are presented to substantiate the effectiveness and merits of the obtained results.展开更多

However, little attention has been paid to their genetic association. This study found the bak1 bik1 double mutant of Arabidopsis displayed a severe dwarfism phenotype due to constitutive immunity and cell death in developing plants. These data suggest that BIK1 cooperates with BAK1 to regulate constitutive immunity and cell death.展开更多
