Abstract: According to length of extension, cutting depth, intensity of activity, sequence of formation and different roles in controlling the basins, the faults may be divided into basement faults and syndepositional ones.Basement faults refer to those that control the formation and distribution of the basins, and often make up boundaries of these basins or of the se-condorder structure units within them. They are characterized by early occurrence, prolonged activity, long extension, large throw and, consequently, greater cutting depth.Syndepositional faults refer to some faults in the basin which occurred somewhat later than the basement faults. They are of smaller extension and cutting depth; their downward extension usually fails of reach the basement of the basin, and gradually disappears in the sedimentary cover. It is obvious that they have controlled such sedimentation as lithofacies and variation of thickness in the basin.These two types of faults not only were extensively distributed but also occurred in great quantities in the process of the formation and evolution of the Mesozoic-Ceuozoic basins in east China. As for the characteristics of their forms, the fault surfaces are generally curved upward, and become gentle in dip with depth, possessing the features of normal fault. Therefore, they are called listric faults.Some ideas are put forward in this paper as to the formation mechanism this sort of listric faults as well as their association with the extension of the basins: 1. The formation of the listric basement faults is closely related to the "thermal events". The transmission of thermal energy from the asthenosphe-re to the earth's crust softens the lower part of the crust and makes it ductile, with the ductility dependent on the temperature. As the temperature rises with the depth, it is reasonably presumed that the ductility will increase to some extent at the greater depths of the crust. A preferred interpretation nowadays is that the listric faults formed through extension in the brittle upper crust was actually the products of ductile stretching in the lower crust, while the formation of the basins was controlled by these faults. 2. On the base of the listric basement fault, there may further occur the listric growth fault. Their formation mechanism was remarkably different from the listric basement fault in that they not only were controlled by extension, buy, what is more important, could be formed mainly as a result of gravity or pressure difference of sediments. This sort of faults are rather widespread in Mesozoic-Cenozoic basins in east China. 3. In the large-size basins of east China, the downward extension or the bottom of the listric normal faults is generally in the range of 5-15 km below the surface, as can be examplified by the well-known Cangdong and Shengbei basement faults. 4. Jn the basin controlled by extension and stretching, the original geological boundaries, such as bedding surface, boundary between the cover an
Producing Terahertz Conherent Synchrotron Radiation Based On Hefei Light Source

Abstract: This paper theoretically proves that an electron storage ring can generate coherent radiation in THz region using a quick kicker magnet and an ac sextupole magnet. When the vertical chromaticity is modulated by the ac sextupole magnet, the vertical beam collective motion excited by the kicker produces a wavy spatial structure after a number of longitudinal oscillation periods. We calculate the radiation spectral distribution from the wavy bunch in Hefei Light Source(HLS). If we reduce electron energy to 400MeV, it can produce extremely strong coherent synchrotron radiation(CSR) at 0.115THz.
Constructing the HBV-human protein interaction network to understand the relationship between HBV and hepatocellular carcinoma

Abstract: We catalogued all published interactions between HBV and human proteins, identifying 250 descriptions of HBV and human protein interactions and 146 unique human proteins that interact with HBV proteins by text mining.Integration of this data set into a reconstructed human interactome showed that cellular proteins interacting with HBV are made up of core proteins that are interconnected with many pathways. A global analysis based on functional annotation highlighted the enrichment of cellular pathways targeted by HBV.By connecting the cellular proteins targeted by HBV, we have constructed a central network of proteins associated with hepatocellular carcinoma, which might be to regard as the basis of a detailed map for tracking new cellular interactions, and guiding future investigations.Hepatitis B virus is one of the most common infectious diseases in the world, and 43 years after its discovery, it still has a great impact on health, particularly in developing countries. More than 350 million people worldwide are known to be chronic carriers of HBV, and each year 15 million people die of hepatitis [1].The HBV viral genome is a relaxed-circular, partially duplex DNA of 3,200 base pairs. It has five genes encoding polymerase, pre-S1/pre-S2/S, X protein, precore/core protein, and the ID2828293 gene which is not well understood without an official gene symbol or description[2]. These proteins can also trans-activate other cellular genes, which may play a role in hepatocarcinogenesis [3].Hepatocellular carcinoma is one of the most common fatal cancers worldwide [4]. HBV is strongly associated with HCC by its presence in the tumor cell and by the striking role of persistent HBV infection as a risk factor for the development of HCC[2]. The incidence of HCC in many countries is increasing in parallel to an increase in chronic HBV infection[1]. It is generally shown that vaccination significantly decreases the incidence of HCC. Moreover, preventing the most severe HBV diseas

Abstract: Gordon首先采用带有非对称双阱势的氢键链模型研究了氢键铁电体的电导性,给出了扭结解和迁移率的表达式.但是对于电导有贡献的扭结孤子应该对应于质子在两个阱底之间的转移,基于这种考虑,修正了Gordon的结果,重新导出了低能态的扭结解,给出了迁移率的一个新的表达式.当非对称双阱势转化为对称双阱势时,这个表达式恰与以前的研究结果一致.这个表达式表明,相变临界指数是1.

Abstract: Based on an analysis of the features of the sediments, sedimentary structures, the relationships among the sequences in the basin and the tectonic disturbances after the basin was formed, some suggestions are given as follows: 1. The Hengyang Basin is a down-warping basin developed on a Caledonian basement. The basin filled with thick clastic-sulfate rocks during the Cretaceous-Paleogene. The types of sedimentary facies in the basin are characterizeda wide range of piedmont-proluvial, fluvial, delta and lacustrine facies. y 2. The succession of the sedimentary facies above mentioned suggests adevelopment process from the paramolasse association, the inland fluvio-lacu-strine red clastic association, and the inland salt lake saline association, finally to the inland plain clastic association. 3. The formation of the Hengyang basin was preceded by the early phase of the Yanshanian Movement and ended with the early stage of the Himalayan. The effect of the succeeding phases of the date Yanshanian was also imprinted on the characteristics of this basin.1.There was intense compression in a northwest-southeast direction in the basin during the Late Himalayan Stage, forming a series of thrusts. The tectonic pattern of the basin has been significantly reworked. The pattern of the basin and the features of the gravity and magnetic anomalies that we see today are the products of this rework.

Abstract: Based on the algebraic graph theory, the networked multi-agent continuous systems are investigated. Firstly, the digraph (directed graph) represents the topology of a networked system, and then a consensus convergence criterion of system is proposed. Secondly, the issue of stability of multi-agent systems and the consensus convergence problem of information states are all analysed. Furthermore, the consensus equilibrium point of system is proved to be global and asymptotically reach the convex combination of initial states. Finally, two examples are taken to show the effectiveness of the results obtained in this paper.

Abstract: According to the lithological characters and the evolution of sc(limentation, five transgression-regression cycles Can be distingguished from the Cretuceous to the Paleogene on the southwestern margin of the Tarim basin. The evolution of the southwest Tarim basin was controlled by the Taras-Fergana fault and the northward subduction of the Indian plate during K-E. A comparative stady of the sedimentary sequences on both sides of the southwestern margin of the Tarim basin ,indicated that. The Sedimenfory-ectonic evolution of the southwest Tarim Basin may be divided intO two stages: The firSt stage was in Early Cretaceous, during which the inherited Strike-slip faultdown basin was formed, and the second sarge was from hate Cretuceous to Paleogene, when the foreland basin was developed with the invasion of the sea water of Tethys.
