Control and Synchronization of Chaos in RCL-Shunted Josephson Junction with Noise Disturbance Using Only One Controller Term
Di-Yi Chen,Wei-Li Zhao,Xiao-Yi Ma,Run-Fan Zhang
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/378457
Abstract: This paper investigates the control and synchronization of the shunted nonlinear resistive-capacitive-inductance junction (RCLSJ) model under the condition of noise disturbance with only one single controller. Based on the sliding mode control method, the controller is designed to eliminate the chaotic behavior of Josephson junctions and realize the achievement of global asymptotic synchronization of coupled system. Numerical simulation results are presented to demonstrate the validity of the proposed method. The approach is simple and easy to implement and provides reference for chaos control and synchronization in relevant systems.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809027159
Abstract: The title compound, 14β-acetoxy-7α-hydroxy-ent-kaur-16-ene-3,15-dione or glaucocalyxin B, C22H30O5, a natural ent-kaurane diterpenoid, is composed of four rings with the expected cis and trans ring junctions. In the crystal structure, there are two molecules in the asymmetric unit related by a noncrystallographic twofold screw axis, and ring A is disordered [ratio occupancies 0.829 (19):0.171 (19)], such that both chair and boat conformations are present, but with the boat conformation as the major component. In the crystal, molecules are linked by intermolecular O—H...O hydrogen bonds.

The Influence of Zen Culture on Chinese Art Design
Xiao-yi HU
Canadian Social Science , 2007,
Abstract: Zen is the product of Buddhism and Chinese culture, as the part of which ,it has penetrated into our daily life, and surpassed itself. Zen gives traditional Chinese art design special color and influences people ‘s thought of design esthetics, style of design esthetics, all these become our traditional ways of expression. But the influence of Zen is seldom noticed. Now people come to know the importance of traditions. this article try to talk about Zen’s influence on Chinese art design and its significance by three points: the sense of “yijing”, space and natural consciousness. Key words: zen, Buddhist Culture, art design, traditional culture Résumé: Le zen est le produit de la combinaison du bouddhisme et de la culture chinoise. En tant que partie de notre culture, il pépètre déja dans tous les domaines de notre vie quotidienne. La culture Zen permet au deisign artistique traditionnel de Chine de revêtir des aspects originaux, influe dans une large mesure sur l’esthétique du design et devient ainsi un moyen spécial d’exprimer la sentiment et l’esthétique nationaux. Cependant, l’influence de l’école Zen sur l’art est rarement invoquée. Il est nécessaire de reconsidérer son influence dans le contexte où l’on insiste sur le retour à la tradition nationale du design. L’article présent tente d’aborder comment l’école Zen influence la pensée artistique traditionnelle de Chine et sa conception du design sous les angles de la conception de l’état d’ame, la conscience spatiale et la conscience naturelle dans le design artistique, et d’explorer la portée actuelle de cette influence. Mots-Clés: école Zen, culture bouddhique, design artistique, culture traditionnelle
Cyclopeptides from Amanita exitialis
Jing-Hua Xue,Ping Wu,Yu-Lang Chi,Liang-Xiong Xu,Xiao-Yi Wei
Natural Products and Bioprospecting , 2011, DOI: 10.1007/s13659-011-0013-9
Abstract: A new cyclic nonapeptide, amanexitide (1), along with the known cyclopeptides, α- and β-amanitins, was isolated from the fruiting bodies of Amanita exitialis, a newly described poisonous mushroom endemic to Guangzhou, Guangdong Province, China. Its amino acid composition and absolute configuration were determined by chemical degradation and derivatization followed by chiral GC analysis. Its amino acid sequence was elucidated by extensive analysis of ESIMS/MS and FTICRMS data. The occurrence of 1 in this mushroom is interesting because it has a structure closely related to antamanide, a cyclic decapeptide with antidote activity against amatoxins and phallotoxins, occurring in A. phalloides.

Journal of Chongqing Normal University , 2009,
Abstract: The purpose of this study is to investigate young private kindergarten teachers' mental health and job burnout states. We use SCL-90, MBI(Maslach Burnout Inventory) and working environment & social and economic station to survey kindergarten teachers, and analyses the data of 195 young kindergarten teachers in private kindergartens. We have found:1)Positive detection rate of project is 47.18%, teachers who have at least one abvious positive symptoms cover 8.27%. 2) The positive symptoms and number of items of youth-run private kindergarten teachers are significantly lower than public kindergarten teachers. 3) Emotional exhaustion dimension score is 31.07±8.81,depersonality dimension score is 9.93±5.13,sense of achievement dimension score is 41.99±10.79. The final results show that:1)The level of mental health of young private kindergarten teachers is relatively low, mental health problems are somewhat serious, but the overall situation is better than public kindergarten teachers. 2) 8.72% of the private kindergarten teachers have relatively serious psychological barriers, mainly manifested in factors as fear, depression, hostility and anxiety. 3) The career achievement of private kindergarten teachers is higher while they have medium depersonality level and more serious emotional exhaustion.

Abstract: Based on 44 groups of soil infiltration experiments in Yangling district, this paper analyzed the scaling process of Philip equation and disclosed the spatial variability of infiltration characteristics in Yangling district by using scaled theory, traditional statistical and geostatistics method. The results showed that the scaling of infiltration process based on aA was best among different scaling factors. The variable coefficient Cv of scaling factor aA was 0.257 5 which was medium variability, and aA was showed to be logarithmic normal distribution. Scaling factor aA was a second-order trend, and the best theoretical model of spatial variability of aA was spherical model, the proportion between nugget and sill was 0.228 0, showing aA had anisotropy and strong spatial correlation, and structural factors mainly caused the spatial variability of scaling factor aA. The results of ordinary Kriging interpolation showed that aA and the spatial distribution characteristics of accumulative infiltration in 90 min highly agreed with each other. The predicted values of aA of the 44 groups and accumulative infiltration in 30 min, 60 min, 90 min are compared with the measured values, and the mean absolute errors were 12.25%, 28.15%, 25.56% and 24.57%, respectively. Taking the actual situation into consideration, the predicted values in method of this paper is totally acceptable.
