The Analysis of Interest Rate Pricing and Its Impact on P2P Platform in the Scalper Arbitrage Environment  [PDF]
Jianqing Huang, Xiao Liu
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.64015
Abstract:
At present, China’s P2P platform has emerged a group of people known as net loan scalper. They borrowed money at low interest rates and invested the high interest rates loans in order to earn profit margins. This paper intends to discuss the factors influencing the loan interest rate into the scalper arbitrage environment from the microcosmic point of view, and focuses on the construction of multiple regression model of 35,970 real transaction data from Hongling Capital, and confirmed that the amount of loan, the term of loan, the mode of repayment, the type of the subject and the lowest bid limit have a significant impact on the setting of the loan interest rate, as well as in the scalper arbitrage environment and no scalper arbitrage environment, the impact of these variables are different. Therefore, platform and users should treat the scalper arbitrage dialectically and learn to identify the risks behind it so as to avoid them.
Analysis of Infrared Radiation Characteristics and Penetration Measures of Warhead  [PDF]
Xiao Liu, Yehui Li
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.611016
Abstract:
Ballistic target recognition occupies a unique and important position in many application fields of target recognition because of its challenge and important position of ballistic missile defense in national security; recognition time of defense system becomes very limited because of ballistic missile high-speed flight; recognition distance of defense system is also due to stealth technology. The integrated application of active jamming and passive decoy greatly increases the difficulty of identification of defense system. Because of its special status and challenge, ballistic target recognition has attracted wide attention of researchers at home and abroad, making it one of the most important issues in infrared target recognition research at home and abroad. In this paper, the infrared characteristics of a ballistic missile warhead target/decoy are analyzed, and the corresponding penetration measures are put forward according to the analysis results.

The Leading Behaviour of The Ground-State Energy of Heavy Ions According to Brown and Ravenhall
Xiao Liu
Physics , 2010,
Abstract: In this article we prove the absence of relativistic effects in leading order for the ground-state energy according to Brown-Ravenhall operator. We obtain this asymptotic result for negative ions and for systems with the number of electrons proportional to the nuclear charge. In the case of neutral atoms the analogous result was obtained earlier by Cassanas and Siedentop [4].
The Dirac Operator on Regular Metric Trees
Xiao Liu
Physics , 2015,
Abstract: A metric tree is a tree whose edges are viewed as line segments of positive length. The Dirac operator on such tree is the operator which operates on each edge, complemented by the matching conditions at the vertices which were given by Bolte and Harrison \cite{BolteHarrison2003}. The spectrum of Dirac operator can be quite different, reflecting geometry of the tree. We discuss a special case of trees, namely the so-called regular trees. They possess a rich group of symmetries. This allows one to construct an orthogonal decomposition of the space $L^2(\Gamma)$ which reduces the Dirac. Based upon this decomposition, a detailed spectral analysis of Dirac operator on the regular metric trees is possible.
Magnetron Sputtering Coating of Protective Fabric Study on Influence of Thermal Properties  [PDF]
Yunqi Zhai, Xiaoxia Liu, Li Xiao
Journal of Textile Science and Technology (JTST) , 2015, DOI: 10.4236/jtst.2015.13014
Abstract: Protective fabric has been the focus of research of the textile materials. In recent years, with the rapid development of the robot, its protective fabric has been developed quickly. This paper is making Al, SiO2 as the sputtering target materials, magnetron sputtering as technology, on the back of the fabric sputtering Al layer, double-layer Al/SiO2 film, and three-layer SiO2/Al/SiO2 film through the test of the heat reflectivity of the composite materials. As a result, the highest reflectivity of the SiO2/Al/SiO2, SiO2/Al, and single Al film is 64.97%, 57.38%, and 51.59%, respectively. It is clear that reflectivity increases with the increase of the membrane layer. In three kinds of membrane structures, there are nanometer Al particles in the formation of dense membrane structure, which can improve the reflectivity of the fabric.

Xinzhi Cao, Fang Liu, Jia Liu, Xiao Tan, Linsheng Ren
Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.611106
Abstract: By the Soxhlet extraction, ethanol is used as extraction solvent of lees to determinate the total phenol content of Xiaoqu spirits lees. Folin-phenol method is handled to extract and to determine the reducing ability of extraction. The total phenolic content in the most suitable condition is determinated by the Folin-phenol method and the optimum extraction technological condition of total phenol is determinated by the experiment. The experimental results show that the optimization conditions of the determination methods of total phenolic content are determined by 3.5 mL for the Folin phenol reagent, 1:1 for the 10% Na2CO3 ratio and 30 min for the chromogenic reaction at room temperature. The optimum extraction technological condition of total phenol from lees is as following: solid-liquid ratio 1:12, ethanol concentration 100%, extraction temperature 80℃, extraction time 10 h.
Iteration and Iterative Roots of Fractional Polynomial Function
Xiao-hua Liu
International Journal of Mathematics and Mathematical Sciences , 2012, DOI: 10.1155/2012/365956
Abstract: Iteration is involved in the fields of dynamical systems and numerical computation and so forth. The computation of iteration is difficult for general functions (even for some simple functions such as linear fractional functions). In this paper, we discuss fractional polynomial function and use the method of conjugate similitude to obtain its expression of general iterate of order n under two different conditions. Furthermore, we also give iterative roots of order n for the function under two different conditions.
Modeling and Analysis of Epidemic Diffusion within Small-World Network
Ming Liu,Yihong Xiao
Journal of Applied Mathematics , 2012, DOI: 10.1155/2012/841531
Abstract: To depict the rule of epidemic diffusion, two different models, the Susceptible-Exposure-Infected-Recovered-Susceptible (SEIRS) model and the Susceptible-Exposure-Infected-Quarantine-Recovered-Susceptible (SEIQRS) model, are proposed and analyzed within small-world network in this paper. Firstly, the epidemic diffusion models are constructed with mean-filed theory, and condition for the occurrence of disease diffusion is explored. Then, the existence and global stability of the disease-free equilibrium and the endemic equilibrium for these two complex epidemic systems are proved by differential equations knowledge and Routh-Hurwiz theory. At last, a numerical example which includes key parameters analysis and critical topic discussion is presented to test how well the proposed two models may be applied in practice. These works may provide some guidelines for decision makers when coping with epidemic diffusion controlling problems.
Situation of sewage input reflected by nitrogen isotopic composition in a sediment core of Hongfeng Lake
Huayun Xiao,Congqiang Liu
Chinese Science Bulletin , 2006, DOI: 10.1007/s11434-006-0971-1
Abstract: Nitrogen in Hongfeng South Lake water mainly comes from sewage with high N concentrations from Pingba Chemical Fertilizer Plant (PCFP). Studies on the sediment core HF010427 sampled in the lake showed that the upward increase of nitrogen isotopic composition of sedimentary organic nitrogen (δ15Norg) accorded with the trend of industrial total production (TP) of PCFC. On the contrary, diagenesis will theoretically cause an upward decrease of δ15Norg. Because no treatment of sewage water was carried out, TP corresponds with sewage emission, indicating that sedimentary δ15Norg can reflect well the total trend of sewage input. The very similar profile shape between nitrogen isotopic composition of sedimentary absorbed ammonium (δ15NH4 absorbed +) and TP of PCFP suggests that δ15NH4 absorbed + can be used to reconstruct more detailed situation of sewage input. The study has a reference to history investigation of sewage input.
