Redundant control inputs have wide applications in engineering, and have significant effects in quadratic performance optimal control, Hcontrol, tracking control, and many uncertain systems. In this paper, using some properties related to the inequality of the special matrix and the transformation of the matrix equation, we present new bounds of the solution of the continuous algebraic Riccati equation. The new bounds are more precise than those proposed in some existing studies on this topic. Subsequently, two lower bounds are presented for the optimal controller gain of the system(1), and a new upper bound is obtained for the optimal controller gain of the extended control system(3). Several examples are provided to demonstrate that our bounds of the optimal controller gain are superior to some previous results. Subsequently, we provide the applications of the new bounds in relevant redundant control problems and obtain good results. Finally,the corresponding numerical examples are provided to illustrate the effectiveness of our results and to compare them with the existing results.

This study focuses on the loading of catalytic materials, e.g., palladium on the surface of supporting materials, with the aim to obtain catalysts with high activity for methane combustion. The catalyst PdO/CeO2- A12O3 was prepared by impregnation under ultrasonic condition. The effect of different activation methods on the activity of catalysts for methane catalytic combustion was tested. The properties of reaction and adsorption of oxygen species on catalyst surface were characterized by 1-12- temperature programmed reduction （H2-TPR）, and 02- temperature programmed desorption （O2-TPD）. Further- more, the sulfur tolerance and sulfur poisoning mode were investigated. The results indicate that the catalyst PdO/ CeO2-A12O3 activated with rapid activation shows higher activity for methane combustion and better sulfur toler- ance. The result of sulfur content analysis shows that there is a large number of sulfur species on the catalyst＇s surface after reactivation at high temperature. It proves that the activity of catalysts cannot be fully restored by high- temperature reactivation.

胰腺癌是一种高度恶性的消化系统肿瘤,5年生存率仅有9%。近年来,胰腺癌发病率和死亡率呈现持续上升趋势,发病群体也将出现年轻化趋势。筛查胰腺癌高危人群可能是提高胰腺癌治疗效果及改善预后的有效措施。液体活检作为一种无创检测手段,通过检测循环肿瘤细胞、循环肿瘤基因、外泌体等以实现肿瘤的辅助诊断,具有易于获得和允许实时监测肿瘤演变等优势。本文聚焦于胰腺癌的危险因素以及基于胰腺癌不同样本类型的辅助诊断技术和新型标志物。

CASTLEMAN＇S disease（CD）,a rare lymphoproliferative disorder of unknown etiology, was first described in 1956 as a benign mass in the mediastinum. Although CD can present anywhere in the body, 70% of the cases are in the chest along the tracheobronchial tree or hilum of the lung in the middle mediastinum; however, they can also occur in the anterior or posterior compartments. CD is classi-fied as unicentric （UCD） or multicentric （MCD） based on the anatomical distribution, and histologically as hya-line-vascular, plasma cell, or mixed subtypes.1 Although MCD is less common than UCD, it can be rapidly pro-gressive and often fatal.

In response to the strong drive for social and economic development, local governments have implemented urban master plans, providing measures and timeframes to address the continuous demand for land and to alleviate urban problems. In this paper, a multi-objective model was constructed to discuss the problem, including economic benefits and ecological effectiveness, in terms of land use optimization. A genetic algorithm was then adopted to solve the model, and a performance evaluation and sensitivity analysis were conducted using Pareto optimality. Results showed that a set of tradeoffs could be acquired by the allocation of land use. In addition, the Pareto solutions proved the model to be efficient; for example, a limit of 13,500 ha of urban area conformed to plan recommendations. The reduction in crop land, orchard land, grassland, and unused land provided further efficiencies. These results implied that further potential regional land resources remain and that the urban master plan is able to support sustainable local development in the years to come, as well as verified that it is feasible to use land use allocation multi-objective modeling and genetic algorithms.

中国的人才测评经过多年的发展已成为一种新兴行业。在繁荣的背后,隐含着人才测评的合法性危机问题。学界对测评的功能分析的忽视,是这些危机的产生重要原因。应对人才测评合法性危机,有诸多策略,如:认清人才测评的社会建制机理,规避人才测评的合法性危机;说明人才测评自身固有的特点,解释人才测评的合法性危机;优化人才测评理论与方法应用的条件,减轻人才测评的合法性危机;规范人才测评的运作流程,消解人才测评的合法性危机;走出科学主义心理测评观的误区,重建人才测评的学理合法性;反对西方测评理论的话语霸权,重建人才测评的历史合法性等。
