This paper is concerned with control and optimization for a sampled-data system with quantization and actuator saturation. Based quantization and actuator saturation a controller is introduced. The corresponding closed loop system is transformed into a system with input saturation and bounded external disturbance. A new Lyapunov functional is constructed to derive a sample-interval dependent condition on the existence of a state feedback controller such that the closed-loop system is exponentially convergent to an ultimate ellipsoid for the initial condition starting from some initial ellipsoid. Based on the condition, the desired controller is designed. Furthermore, optimization problems about the sample-interval, the ultimate ellipsoid and the initial ellipsoid are formulated. An example is given to illustrate the effectiveness of the proposed method.

探究添加不同比例(1%、2%、4%)鹰嘴豆分离蛋白(chickpea protein isolate,CPI)对减盐大骨鸡鸡肉丸凝胶品质的影响。测定不同处理组减盐大骨鸡鸡肉丸的质构特性、色泽、水分分布、流变特性和微观结构。结果表明:(1.4%NaCl、4%CPI)处理组的减盐大骨鸡鸡肉丸的硬度、弹性、咀嚼性显著高于其他处理组(P<0.05)。低场核磁共振分析显示,CPI添加量为4%的减盐大骨鸡鸡肉丸具有最高的P21和最低的P22,证明该条件下的减盐大骨鸡鸡肉丸持水性最佳。流变学特性显示,(1.4%NaCl、4%CPI)处理组的减盐大骨鸡鸡肉丸的储能模量最大,弹性最佳。扫描电镜显示,(1.4%NaCl、4%CPI)处理组的减盐大骨鸡鸡肉丸凝胶与其他处理组相比,结构更紧实,连续性更好。综上所述,添加1.4%NaCl、4%CPI有利于提高CPI减盐大骨鸡鸡肉丸的凝胶品质。

Separation of palladium(Pd)and platinum(Pt)by solvent extraction is difficult because of their extremely similar physicochemical *** of new extractants with a high extraction efficiency and excellent separation selectivity is the primary focus for enhancing the separation of Pd and Pt by solvent *** this study,a new extractant,2-((2-methoxyethyl)thio)-1 H-benzimidazole(MOBI),which contains N,S,and O atoms,was synthesized and used to separate Pd(Ⅱ)and Pt(Ⅳ)from a hydrochloric acid aqueous *** experimental results revealed that Pd(Ⅱ)and Pt(Ⅳ)were effectively separated under the optimal conditions:MOB I concentration of 0.005 mol·L^(-1),HCl concentration of0.2 mol·L^(-1),organic/aqueous(O/A)phase ratio of 1.0,and contact time of 15 *** separation coefficient between Pd(Ⅱ)and Pt(Ⅳ)was 1246.40,which indicates that MOBI has a higher selectivity for Pd(Ⅱ)than Pt(Ⅳ).In addition,the mechanism of coordination between Pd(Ⅱ)and MOBI was demonstrated through the slope method,Fourier transform infrared spectroscopy(FTIR),hydrogen-1 nuclear magnetic resonance spectroscopy(^(1)H NMR),and carbon-13 nuclear magnetic resonance spectroscopy(^(13)C NMR).The results revealed that MOBI could coordinate with Pd(Ⅱ)via the N atom in the benzimidazole ring of MOBI molecules to form[Pd(MOBI)_(2)Cl_(2)](O).

In 4-dimensional R-gravity, using the linear and square terms of the expanding expression of the space-time connection, we calculate the possible curvature excitation （order k^4） of gravitational field, which is given by the first term of quantum Wilson loop （w） through two-point Green＇s function of the connection. At the same time using the tree diagram propagators of gravitons, the lowest order （k^4） correction to （w） is also calculated through the graviton self-energy in the term. Under the accuracy condition up to order k^4, we have obtained a complete expression of the excitation contributed from the leading term （w^（2））of （w）.

Plate tectonics is the most important discovery in Earth Science in the 20th Century and is the core theory of Solid Earth Science. It describes that the Earth’ s lithosphere is divided into several plates that slide on top of the asthenosphere and move relative to each other along divergent, convergent, and transform plate boundaries. From a physical point of view.
