Estimating Probability Distribution of Asset Value Based on Dual Effects of Deposit Insurance with the Minimum Cross-Entropy Principle  [PDF]
Xiaoning Lv, Xuezhi Qin, Tao Sun
Theoretical Economics Letters (TEL) , 2013, DOI: 10.4236/tel.2013.33A005
Abstract:

A model is proposed to estimate the probability distribution of asset value based on the benefit effects as well as the risk effects of deposit insurance with the minimum cross-entropy principle. Three scenarios are constructed to depict situations with different dual effects of deposit insurance. The corresponding assets distribution functions are obtained accordingly. The results show that it is positively correlated between the supervision level and the risk aversion effects of deposit insurance. The increase of the deposit insurance premium moves the bank’s assets distribution to the right side although not significantly. The asset probability distributions estimated in this paper can be taken as a reference for banks to choose the proper credit investment projects.

The Study of Chinese Listed Bank’s Efficiency Growth Mode in Internet Finance Era—Based on Full-Combination DEA-PCA Model  [PDF]
Jianwen Qin, Tao Wang, Bangding Huang
American Journal of Industrial and Business Management (AJIBM) , 2016, DOI: 10.4236/ajibm.2016.611098
Abstract: In the era of internet finance, the scholars and practitioners around the world are paying attention to how to enhance the competitiveness of commercial banks by choosing the appropriate growth pattern of business performance. This paper uses empirical research to discuss the growth model of business performance within 16 listed commercial banks in China by full-combination DEA-PCA model. We find that there are significant differences on the performance evaluation of each listed bank due to whether they consider internet factor or not. Furthermore, we apply PCA model which is based on the result of full-combination DEA model to classify the growth pattern of business performance into “Internet Business Oriented” which enhances performance by internet finance innovation and “Traditional Business Oriented” which maintains performance by traditional banking business. According to the performance of each listed bank in the PCA analysis chart, we classify these banks further into four groups: “Emphasis on internet business”, “Emphasis on traditional business”, “Emphasis on internet business with overburdened traditional business” and “Balance between internet business and traditional business”. Each group of banks has its own strength and weakness. At last, according to the characteristics of different bank groups, we put forward the corresponding efficiency strategy recommendations.
Research on Order Decision of Quantity Flexibility Contract under the Competition between Multiple Suppliers and Multiple Retailers  [PDF]
Cheng Qian, Yanan Tao, Zhilin Qin
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.89127
Abstract: In the supply chain system consisting of multiple suppliers and multiple retailers, in order to realize supply chain coordination, we studied the ordering decision under the quantity flexibility contract with competition between both sides. On the one hand, from the perspective of suppliers, a satisfactory production of goods for each supplier was obtained by means of a kind of interactive programmer step method. On the other hand, from the perspective of retailers, because each supplier holds a different preference attitude for different retailers, we sort retailers as preference in application of a group decision sequencing method of Markov chain. The optimal order quantity of goods for each retailer was obtained at the same time and we prove that it is Pareto optimal. Finally, we give a numerical example.
An Enhanced Scheme against Node Capture Attack using Hash-Chain for Wireless Sensor Networks
Tao Qin,Hanli Chen
Information Technology Journal , 2012,
Abstract: Node capture is a severe threat to data security in Wireless Sensor Networks(WSNs). This paper aimed to design an enhanced and efficient scheme against node capture attack using hash-chain in wireless sensor networks. Key management is the fundamental security mechanism in wireless sensor networks, but existing schemes based on probability have poor resistance to node capture attack. In order to improve the resilience against node capture attack, a hash-chain based scheme to resist node capture attack was presented. The main idea of the proposed consisted of applying a hash function on the initial preloaded keys before deployment. During the key pre-distribution, the selected keys were hashed according to certain rules and the hashed results were as communication key. Theoretical analysis and simulation results show that, key exposal probability and average insecure degree decrease by 56 and 46% compared to existing algorithms, respectively. Through hash chain technique that conceals the same keys used to secure different links, the proposal outperforms other schemes in resilience against node capture attack and enhance the overall survivability of the network.
Scheme for the implementation of optimal cloning of arbitrary single particle atomic state into two photonic states
Wei Song,Tao Qin
Physics , 2006,
Abstract: We present a feasible scheme to implement the $1 \to 2$ optimal cloning of arbitrary single particle atomic state into two photonic states, which is important for applications in long distance quantum communication. Our scheme also realizes the tele-NOT gate of one atom to the other distant atom trapped in another cavity. The scheme is based on the adiabatic passage and the polarization measurement. It is robust against a number of practical noises such as the violation of the Lamb-Dicke condition, spontaneous emission and detection inefficiency.

Chaoling Qin, Zhiyong Hao, Tao Zhang, Yanhua Guo
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.46011
Abstract: This thesis mainly studies the relationship between sports lifestyle and physical health of college students. Taking 300 students in Lvliang College as subjects, by the way of the literature review, questionnaire surveys, physical tests, mathematical statistics and so on, this paper analyzes students’ body quality and physical health. In this paper, constituent elements of sports lifestyle include: sports behavior subject, behavior characteristics, behavior benefit (the article names the four different kinds of lifestyle excellent-grade, good-grade, middle-grade and bad-grade); physical health include: body shape, body function and body quality. This article analyzes and compares some factors of body shape, body function and body quality, such as weight, vital capacity, BMI, lung index, 50-meter, 800-meters (girls), 1000-meters (boys), sit and reach, one-minute sit-up (girls), and pull-up (boys). The results show that students with good sports lifestyle have better physical health than students with bad sports lifestyle. It is quite visible that a good sports lifestyle is a vital factor of students’ physical level. Setting a good sports lifestyle can improve body quality, promote the development of flexibility, speed and stamina, which eventually promote the all-round development of students’ physique. At the end of this thesis, the author suggests that college students should form a positive and healthy life behavior.
Studies on the Inclusion Behavior of Amphiphilic p-Sulfonatocalix[4]arene with Ascorbic Acid by Spectrofluorometric Titrations  [PDF]
Yunyou Zhou, Xueping Ding, Xiaoli Fang, Tao Li, Dongbao Tang, Qin Lu
Optics and Photonics Journal (OPJ) , 2011, DOI: 10.4236/opj.2011.12009
Abstract: The aqueous solution of tetrabutyl ether derivatives of p-sulfonatocalix[4]arene (SC4Bu) and ascorbic acid (AA) complex has been studied based on fluorescence and 1H NMR spectroscopic results. It was found that the fluorescence intensity of SC4Bu quenched regularly upon the addition of AA. A 1:1 stoichiometry for the complexation was established and was verified by Job’s plot. The temperature-dependent inclusion constants were calculated, form which Δ H and ΔS values were calculated. Meanwhile the proposed interaction mechanism of the inclusion complex was discussed based on 1H NMR results. The various factors (ionic strength, and surfactants) effecting the inclusion process were examined in detail.

Shaoqiang Tao, Juan Li, Xungang Gu, Yanan Wang, Qiang Xia, Bing Qin, Lin Zhu
American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.31004
Abstract: Tea plant (Camellia sinensis) has unique biological features for the study of cellular and molecular mechanisms, an evergreen broad-leaved woody plant which can accumulate selenium in soil abundant of Selenium. Expression of the genes related to Selenium (Se) metabolism is an adaptation to the soil environment for a long period. The purpose of the present study was to explore if there exist differences of expression about these genes in tea plant between growing in Selenium-abundant and normal soil. A quantitative real-time reverse transcription polymerase chain reaction (Q-RT-PCR) assay was done for quantification of ATP sulfurylase (APS) and selenocysteine methyltransferase (SMT) mRNA normalized to Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene in tea plant. Young leaves, mature leaves and tender roots from tea plants growing in soil abundant of Selenium were respectively obtained from Shitai County, Anhui Province, and also the relevant materials of the selenium un-enriched tea plant planted at agricultural garden of Ahui Agriculture University were taken as control for real-time PCR analysis. The results showed that APS1, APS2 and SMT expression levels for either young or mature leaves in selenium-enriched tea plant were lower than that in ordinary (selenium un-enriched) tea plant. In contrast, the APS1, APS2 and SMT expression level of roots in selenium-enriched tea plant were all higher than that in ordinary tea plant. APS1 gene expression level of roots in selenium-enriched tea plant was about 1.6 times higher than that in the ordinary tea plant, APS2 gene expression level was about 4.8-fold higher than that in the ordinary tea plant, SMT gene expression level was about 3.3 times higher than that in the ordinary tea plant. Among various tissues of selenium-enriched tea plant, APS1 gene relative expression level of young leaves was similar to or slightly higher than mature leaves, and the one of roots was the lowest among them; APS2 gene relative expression level of young leaves was similar to or slightly higher than the roots, and the one of mature leaves was the lowest among them; SMT gene relative expression level of young leaves was similar to or slightly higher than mature leaves, and the one of roots was the highest among them. Our results suggest that there existed correlation between selenium and expression levels of these genes.
Isolation and expression characterization of CBF2 in vitis amurensis with stress  [PDF]
Chang Dong, Jianmin Tao, Meng Zhang, Zhiying Yu, Bailin Wang, Binhua Cai, Zhen Zhang, Yang Qin
Agricultural Sciences (AS) , 2013, DOI: 10.4236/as.2013.49062
Abstract:

The transcription factor VaCBF2, which interacts with C-repeat/DRE and its promoter, was isolated from Vitis amurensis. The VaCBF2 amino acid sequence contained a conserved AP2 domain of 56 amino acids and a potential nuclear localization sequence. The sequence of VaCBF2 showed a high level of homology with other CBF2 family members. Phylogenetic analysis showed that the amino acid sequences may be CBF2 proteins with evolutionary relationship. Quantitative reverse-transcription polymerase chain reaction analysis indicated that the expression of VaCBF2 gene in tissues (roots, stems, leaves, and petioles) was induced by low temperature, high salinity, and application of abscisic acid and salicylic acid in a time-dependent manner but to different extents in the cold-hardy V. amurensis and the less cold-hardy Vitis vinifera. The presence of cis-elements such as MYC and ABRE in VaCBF2 promoter further confirmed that this promoter was a component of the CBF transduction pathway involved in plant response to multiple stresses.
