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.
Developmental toxicity of organotin compounds in animals
Xiao HUANG
Frontiers in Marine Science , 2014, DOI: 10.3389/fmars.2014.00039
Abstract: Organotin compounds (OTs) have been used as biocides in antifouling paints and agriculture. The IMO introduced a global ban on the use of OTs in antifouling systems in 2001 due to their high toxicity. However, OTs have still been detected in the environment and pose a threat to the ecosystem. Several research groups have summarized the analytical methods, environmental fate, biochemistry, reproductive toxicity and mechanisms of actions of OTs. Here, we reviewed the developmental toxicity of OTs in various organisms such as sea urchin, ascidian, mussel and fish. The differences in sensitivity to OT exposure exist not only in different species but also at different stages in the same species. Though some hypotheses have been proposed to explain the developmental toxicity of OTs, the solid evidences are greatly in need.
Scientific Communities Found Based on the Path Structure of Citation Network  [PDF]
Xiao Xiao, Song Cao, Lan Huang, Yutian Tang
International Journal of Intelligence Science (IJIS) , 2012, DOI: 10.4236/ijis.2012.21003
Abstract: Based on the structure of citation network, the citation paths among papers, and the association strength such as coupling, co-citation and etc. between two papers are defined in this article. We give formulas to quantify the association strength in order to establish citation network model based on the citation path structure. Then, the OPTICS algorithm is brought into the scientific communities found model since it can solve the parameter’s setting problem. This method combines various kinds of path structures together and thus it contains more complete citation network information. Experiments and analysis reveal the reliability and validity of this method.

Zhiwei Huang, Bo Xiao, Lisha Zhong
Journal of Biosciences and Medicines (JBM) , 2013, DOI: 10.4236/jbm.2013.11002
Abstract: Objective: On the premise that the image quality meets the requirements of clinical diagnosis, we explored the methods to reduce the radiation dose of coronary artery imaging with Dual-Source CT (DSCT). Methods: We randomly selected 200 patients with coronary heat disease (BIM<25kg/m2), applied the scanning technology of regulating the dose of heart electric pulse (AUTO) on the 100 patients in group A. In this group for different heart rate we chose different full dose exposure time window. For the 100 patients in group B, we used conventional full dose (OFF) scan mode. The DSCT automatically selected the best time and phase to reconstruct the image. We used the 5 point system to evaluate the image quality, measured and compared the image noise and radiation dose. When P<0.05, the differences between the two groups have statistical significance. Results: The image quality scores between the two groups showed no significant difference (P > 0.05). The average image noise in group A is (41.76 ± 7.98) HU, in group B the average image noise is (43.97 ± 3.88) HU, the dif- ference between the two groups was not statistically significant (P>0.05). The average CTDIvol of group A and B were (20.63 ± 2.24) mGy, (38.11 ± 10.69) mGy, respectively, then P <0.01. The average DLP of group A and B are (235.75 ± 28.64) mGycm and (492.59 ± 125.49) mGycm respectively, then P <0.01, the dif- ference of radiation dose had statistical significance (P<0.05). Conclusions: For coronary artery imaging with DSCT the heart electric pulse (AUTO) regulation technology can meet the diagnostic requirements and effectively reduce the radiation dose.
Current status of haploidentical stem cell transplantation for leukemia
Xiao-jun Huang
Journal of Hematology & Oncology , 2008, DOI: 10.1186/1756-8722-1-27
Abstract: Hematopoietic stem cell transplantation is a good, and sometimes only treatment option for the cure of leukemia, especially for patients with high risk factors of relapse and with relapsed leukemia[1]. However, only 30% of patients can find an ideal donor, an HLA-identical sibling. The only option is transplantation from an alternative donor. Although the chances of finding an suitable unrelated donor have been significantly increased due to the expansion of the worldwide unrelated donor program, the application of unrelated donor transplantation remains limited by some major obstacles, including 1) the probability of finding a matched unrelated donor(MUD) ranges from less than 10% in ethnic minorities to 60%~70% in Caucasians[2], 2) the complicated process of searching, HLA-typing, and harvesting an unrelated donor takes an average of about 4 months from initiation of a search to the donation of stem cells. Some patients might relapse or even die during this waiting period[3], 3) moreover, allogeneic transplantation using a matched unrelated donor is still associated with a high transplant-related mortality and high long-term morbidity[4,5]. Unrelated donor umbilical cord blood (UCB) offers the advantages of easy procurement and immediate availability, the absence of risk of donor, and potential reduced risk of GVHD[6]. However, engraftment remains a significant problem, especially for adult patients receiving UCB with low number of hematopoietic stem cells and two-antigen mismatch.The use of mismatched family donors offers several advantages, 1) immediate and easy donor availability, virtually almost all patients have at least one HLA-mismatched relative donor, who is immediately available to serve as a donor; 2) The ability to select the best of many potential donors on the basis of HLA mismatch, age, natural killer (NK) cell alloreactivity[7-9]; 3) Easy access to repeat donation of donor cells again, when donor-derived cellular therapy is needed for the treatmen

Jiangying Huang,Xiao Zhang
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811008798
Abstract: The title compound, [PdBr(C3H5)(C9H8N2)], was synthesized by the reaction of the allylpalladium(II) bromide dimer and 1-phenyl-1H-imidazole. The Pd atom is coordinated by one allyl group [in η3 mode, the central CH group of the allyl group is disordered over two sets of sites in a 0.668 (5):0.332 (5) ratio], one bromide anion and a 1-phenyl-1H-imidazole ligand. Intramolecular face-to-face π–π stacking interactions occur between adjacent phenyl or imidazole groups, with centroid–centroid distances in the range 3.877 (1)–3.6596 (6) , forming a supramolecular chain along [100].
A New Data Structure and Algorithm for Static Slicing Concurrent Programs
Huang Weiping,Xiao Jianyu
Information Technology Journal , 2008,
Abstract: Internal representation and static slicing algorithm of concurrent programs are studied. Based on the comparison among existed slicing algorithms and analysis of the fact that Krinke`s algorithm produced imprecise program slice for the program structure which has loops nested with one or more threads, a conclusion is drawn that the reason for the impreciseness is that Krinke`s data structure-threaded program dependence graph had over coarse definitions of data dependence relations between threads and the constraint put on the execution path in concurrent program is unduly loose. An improved threaded program dependence graph is proposed which adds a new dependence relation of loop-carried data dependence crossing thread boundaries. An improved slicing algorithm is also proposed which introduces a new concept of regioned execution witness to further constrain the execution path. The pseudo code of algorithm adding loop-carried data dependence relations crossing thread boundaries is given. The pseudo code of the new slicing algorithm is also given whose complexity has been analyzed. Examples shows that the improved slicing algorithm designed on the improved data structure can restrain the impreciseness of Krinke`s.

Abstract: OBJECTIVE: To explore the effects and mechanisms of combining astragaloside Ⅳ (the effective component of Astragalus membranaceus) with notoginsenoside R1, ginsenoside Rb1 and ginsenoside Rg1 (the effective components of Panax notoginseng) against oxidative injury in PC12 cells induced by cobalt chloride (CoCl2).METHODS: CoCl2 was used to stimulate PC12 cells to induce injury after transdifferentiation with nerve growth factor. Then the PC12 cells were divided into 10 groups and cultured with corresponding drugs. After culture, apoptotic cells were tested by using Hocchst 33258 fluorescent staining, the level of mitochondrial membrane potential (MMP) was analyzed by rhodamine 123 fluorescent staining and the content of reactive oxygen species (ROS) in PC12 cell was measured by dichlorofluorescin diacetate fluorescent staining.RESULTS: CoCl2 induced apoptosis along with the obvious decrease of MMP as well as overproduction of ROS in PC12 cells. Astragaloside Ⅳ, ginsenosides Rg1, ginsenosides Rb1 and notoginsenoside R1 had inhibition effects in different degree on PC12 cell apoptosis induced by CoCl2, reduced the overproduction of ROS and the decrease of MMP. The effects of the combination were better than those of active component alone.CONCLUSION: Active components extracted from Astragalus and Panax notoginseng can inhibit PC12 cell apoptosis induced by oxidative injury, furthermore, the effects were enhanced by combination of these components, which may be associated with jointly antagonizing the generation of ROS and raising MMP.
Fractional Flux Plateau in Magnetization Curve of Multi-Component Superconductor Loop
Zhao Huang,Xiao Hu
Physics , 2015,
Abstract: Time-reversal symmetry (TRS) may be broken in superconductors with three or more condensates interacting repulsively, yielding two degenerate states specified by chirality of gap functions. We consider a loop of such superconductor with two halves occupied by the two states with opposite chiralities. Fractional flux plateaus are found in magnetization curve associated with free-energy minima, where the two domain walls between the two halves accommodate different inter-component phase kinks leading to finite winding numbers in a part of the whole condensates around the loop. Fractional flux plateaus form pairs with their heights related to the flux quantum {\Phi}0 = hc/2e. This phenomenon is a clear evidence of time-reversal symmetry broken (TRSB) superconductivity, which in a general point of view provides a novel chance to explore relative phase difference, phase kink and soliton in ubiquitous multi-component superconductivity such as that in iron pnicitides.
Josephson Effects in Three-Band Superconductors with Broken Time-Reversal Symmetry
Zhao Huang,Xiao Hu
Physics , 2014, DOI: 10.1063/1.4872261
Abstract: In superconductors with three or more bands, time-reversal symmetry (TRS) may be broken in the presence of repulsive interband couplings, resulting in a pair of degenerate states characterized by opposite chiralities. We consider a Josephson junction between a three-band superconductor with broken TRS and a single-band superconductor. Phenomena such as asymmetric critical currents, subharmonic Shapiro steps and symmetric Fraunhhofer patterns are revealed theoretically. Existing experimental results are discussed in terms of the present work.
