Journal of Inequalities and Applications , 2010,
Abstract: We give out a general method to prove the complete convergence for arrays of rowwise -mixing random variables and to present some results on complete convergence under some suitable conditions. Some results generalize previous known results for rowwise independent random variables.

On the Strong Laws for Weighted Sums of -Mixing Random Variables
Zhou Xing-Cai,Tan Chang-Chun,Lin Jin-Guan
Journal of Inequalities and Applications , 2011,
Abstract: Complete convergence is studied for linear statistics that are weighted sums of identically distributed -mixing random variables under a suitable moment condition. The results obtained generalize and complement some earlier results. A Marcinkiewicz-Zygmund-type strong law is also obtained.
Cross Depolarization Effect of Electromagnetic Wave by Partially Charged Spherical Sands in Sandstorms

Abstract: Based on the Rayleigh approximation,the electromagnetic wave illumining on a partially charged sand particle,the forward scattering amplitude function,and the expression of differential attenuation and differential phase shift are derived.We calculated the cross depolarization discrimination of linear polarized wave propagated on the charged dust storm.The results indicate that the partially charged spherical particle also can make the incident wave depolarized,and the depolarization effect firstly increase...
Phylogenetic Relationship of the Firefly, Diaphanes pectinealis (Insecta, Coleoptera, Lampyridae) Based on DNA Sequence and Gene Structure of Luciferase

LI Xue-yan,YANG Shuang,LIANG Xing-cai,

动物学研究 , 2006,
Abstract: Diaphanes is the fourth largest genus in Lampyridae, but no luciferase gene from this genus has been reported. In this paper, by PCR amplification of the genomic DNA, the luciferase gene of Diaphanes pectinealis, which is the first case from Diaphanes, was identified and sequenced. The luciferase gene from D. pectinealis spans 1958 base pairs (bp) from the start to the stop codon, including seven exons separated by six introns, and encoding a 547-residuelong polypeptide. Its deduced amino acid sequence showed high protein similarity to those of the Lampyrini tribe (93 -94%) and the Cratomorphini tribe (92%), while low similarity was found with the North American firefly Photinus pyralis (83%) of the Photinini tribe within the same subfamily Lampyrinae. The phylogenetic analysis performed with the deduced amino acid sequences of the luciferase gene further confirms that D. pectinealis, Pyrocoelia, Lampyris, Cratomorphus, and Photinus belong to the same subfamily Lampyrinae, and Diaphanes is closely related to Pyrocoelia, Lampyris,and Cratomorphus. Furthemore, the phylogenetic analysis based on the nucleotide sequences of the luciferase gene indicates Diaphanes is a sister to Lampyris. The phylogenetic analyses are partly consistent with morphological (Branham & Wenzel, 2003) and mitochondrial DNA analyses (Li et al, 2006).

Abstract: 松辽盆地徐家围子断陷兴城地区火山岩埋藏较深,断层发育且倾角较大,构造极其复杂,常规时间域成像效果较差,且火山岩屏蔽作用明显影响到下伏地层成像精度,对构造解释造成了一定影响.针对这一问题,采用波动方程正演模拟技术,建立反映该区实际复杂构造的模型,进行正演模拟,然后将模拟的炮集记录进行常规处理和叠前偏移处理,重点是叠前深度偏移处理.模拟结果表明,将模型正演技术应用到实际地震资料的处理中,有助于指导实际地震资料中速度-深度模型的建立,并且对于提高复杂构造的成像质量具有非常重要的作用,而且有利于下一步验证构造解释方案是否合理.
Multifractal characteristics of daily discharge series in the Yangtze River

Abstract: The hydrologic process is a very complicated nonlinear system, of which runoff is a very significant component.Single parameter is difficult to characterize the change in the daily runoff time series completely, while the multifractality method with singular spectrum analysis enables us to get more information about the nonlinear behavior of runoff. Based on long-term daily runoff records of Cuntan, Yichang and Datong stations, this article has studied the multifractal temporal scaling properties of the Yangtze River, and fitted the multifractal spectrum by the modified version of the multiplicative cascade model.The results revealed that (1) The discharge series of the Yangtze River is a similar multifractal, and the mulfiractality is caused by the long-term persistence.The long-term persistence of daily runoff may be related to the interactions between precipitation and underlying surface over various ranges of space-time scales. (2) The fits based on universal multifractal model describe well the scaling behavior of positive as well as negative moments in the 3 daily runoff records . The two parameters a and b obtained from the model can be used to calculate the width Δα of singularity spectrum, and the values of a, b and Δα can be regarded as 'fingerprints’ for each station, which can be served as an efficient test for the state-of-the-art precipitation-runoff models. (3) The comparison of the width Δα of singularity spectrum among these three stations revealed that there are spatial differences in the complexity of the daily runoff change on the Yangtze River. The complexity of runoff records on Datong is larger than those of the upper reaches of the Yangtze River, while there is no significant difference between Cuntan and Yichang. The factors contributed to the complexity include the drainage area, constitution of water quantity, the characteristics of precipitation and underlying sufrace, and so on.

Abstract: a triploid (2n = 3x = 36) rice plant was obtained by screening a twin seedling population in which each seed germinated to two or three sprouts that were then crossed with diploid plants. one diploid plant was chosen among the various f1 progenies and developed into an f2 population via self-pollination. compared with the control variety shanyou 63, this f2 population had a stable agronomical performance in field trials, as confirmed by the f-test. the stability of the f2 population was further substantiated by molecular analysis with simple sequence repeat markers. specifically, of 160 markers assayed, 37 (covering all 12 chromosomes) were polymorphic between the parental lines. testing the f1 hybrid individually with these markers showed that each pcr product had only a single band instead of two bands from each parent. the bands were identical to either maternal (23 markers) or paternal (eight markers) bands or distinct from both parents (six markers). the amplified bands of all 60 randomly selected f2 plants were uniform and identical to those of the f1 hybrid. these results suggest that the f1 plant is a non-segregating hybrid and that a stable f2 population was obtained. this novel system provides an efficient means for shortening the cycle of hybrid rice seed production.

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811018575
Abstract: In the title compound, C9H7N5·H2O, the interplanar angles between the benzene and tetrazole rings and between the benzene and imidazole rings are 8.71 (3) and 1.32 (2)°, respectively. In the crystal, strong N—H...N hydrogen bonds link the organic 5-(1H-tetrazol-5-yl)-1H-indole molecules into chains extended along the b axis. The chains are further interconnected into layers parallel to (100) via strong O—H...N and N—H...O hydrogen bonds. Furthermore, the layers are interconnected via strong O—H...N hydrogen bonds. Moreover, cohesion between the layers is provided by the π–π interactions between the imidazole, tetrazole and benzene rings with centroid–centroid distances of 3.766 (2), 3.832 (2) and 3.733 (2) .
