Statistical Diagnosis for General Transformation Model with Right Censored Data Based on Empirical Likelihood  [PDF]
Shuling Wang, Xiaohong Deng, Lin Zheng
Natural Science (NS) , 2014, DOI: 10.4236/ns.2014.610074
Abstract: In this work, we consider statistical diagnostic for general transformation models with right censored data based on empirical likelihood. The models are a class of flexible semiparametric survival models and include many popular survival models as their special cases. Based on empirical likelihood methodologe, we define some diagnostic statistics. Through some simulation studies, we show that out proposed procedure can work fairly well.


Statistical Diagnosis for Random Right Censored Data Based on Kaplan-Meier Product Limit Estimate  [PDF]
Shuling Wang, Xiaohong Deng, Lin Zheng
Open Journal of Statistics (OJS) , 2014, DOI: 10.4236/ojs.2014.44031
Abstract:

In this work, we consider statistical diagnostic for random right censored data based on K-M product limit estimator. Under the definition of K-M product limit estimator, we obtain that the relation formula between estimators. Similar to complete data, we define likelihood displacement and likelihood ratio statistic. Through a real data application, we show that our proposed procedure is validity.

On Diagnostics in Stochastic Restricted Linear Regression Models  [PDF]
Shuling Wang, Man Liu, Xiaohong Deng
Open Journal of Statistics (OJS) , 2014, DOI: 10.4236/ojs.2014.49071
Abstract: The aim of this paper is to propose some diagnostic methods in stochastic restricted linear regression models. A review of stochastic restricted linear regression models is given. For the model, this paper studies the method and application of the diagnostic mostly. Firstly, review the estimators of this model. Secondly, show that the case deletion model is equivalent to the mean shift outlier model for diagnostic purpose. Then, some diagnostic statistics are given. At last, example is given to illustrate our results.
An Empirical Research on the Relations between Higher Education Development and Economic Growth in China
Xiaohong Wang,Shufen Wang
Asian Social Science , 2009, DOI: 10.5539/ass.v4n1p78
Abstract: With the development of science and technology, education is playing a more and more important role in economic growth. Therefore, the relations between higher education development and economic growth have been a hot issue for a long time. By employing the relevance analysis model in the empirical analysis on the role of higher education in economic growth, this article is expected to give some reference to the harmonious development of higher education and economic growth in China.
In Search of Regulators of LeSPL-CNR by South-Western Blotting and Yeast One-Hybrid Library Screening System  [PDF]
Xiaohong Wang, Bishun Ye, Ying Wang, Ting Zhou, Tongfei Lai
American Journal of Plant Sciences (AJPS) , 2018, DOI: 10.4236/ajps.2018.95080
Abstract:

LeSPL-CNR is a crucial transcription factor for fruit ripening of Solanum lycopersicum. The cnr (colorless non-ripening) epimutation resulted from hypermethylation in a 286 bp region of LeSPL-CNR promoter inhibits normal fruit ripening. In present study, potential regulators of LeSPL-CNR, which could bind to the specific 286 bp region, were screened via south-western blotting and yeast one-hybrid (Y1H) library screening system. Results indicated that a total of 13 and 19 candidate proteins were acquired respectively, and both ribulose-1,5-bisphosphate carboxylase/oxygenase and 40S ribosomal protein were identified by two methods. These would provide some information for revealing roles of DNA methylation and the regulatory mechanism for LeSPL-CNR.

Global Stability of a SLIT TB Model with Staged Progression
Yakui Xue,Xiaohong Wang
Journal of Applied Mathematics , 2012, DOI: 10.1155/2012/571469
Abstract: Because the latent period and the infectious period of tuberculosis (TB) are very long, it is not reasonable to consider the time as constant. So this paper formulates a mathematical model that divides the latent period and the infectious period into n-stages. For a general n-stage stage progression (SP) model with bilinear incidence, we analyze its dynamic behavior. First, we give the basic reproduction number . Moreover, if , the disease-free equilibrium is globally asymptotically stable and the disease always dies out. If , the unique endemic equilibrium is globally asymptotically stable and the disease persists at the endemic equilibrium.

Abstract: This paper conducts research on the connotations and characteristics of evaluation indicator system for teaching quality of college teachers, constructs the contents of the evaluation indicator system for teaching quality of college teachers and applies the contents in the practice of teaching quality monitoring and evaluation so as to prove their rationality and practicability and to achieve the aim of improving management level of teaching quality.
Large-time Behavior of Solutions to the Inflow Problem of Full Compressible Navier-Stokes Equations
Xiaohong Qin,Yi Wang
Mathematics , 2010, DOI: 10.1088/0951-7715/24/5/001
Abstract: Large-time behavior of solutions to the inflow problem of full compressible Navier-Stokes equations is investigated on the half line $R^+ =(0,+\infty)$. The wave structure which contains four waves: the transonic(or degenerate) boundary layer solution, 1-rarefaction wave, viscous 2-contact wave and 3-rarefaction wave to the inflow problem is described and the asymptotic stability of the superposition of the above four wave patterns to the inflow problem of full compressible Navier-Stokes equations is proven under some smallness conditions. The proof is given by the elementary energy analysis based on the underlying wave structure. The main points in the proof are the degeneracies of the transonic boundary layer solution and the wave interactions in the superposition wave.
Stability of Wave Patterns to the Inflow Problem of Full Compressible Navier-Stokes Equations
Xiaohong Qin,Yi Wang
Mathematics , 2009,
Abstract: The inflow problem of full compressible Navier-Stokes equations is considered on the half line $(0,+\infty)$. Firstly, we give the existence (or non-existence) of the boundary layer solution to the inflow problem when the right end state $(\rho_+,u_+,\theta_+)$ belongs to the subsonic, transonic and supersonic regions respectively. Then the asymptotic stability of not only the single contact wave but also the superposition of the boundary layer solution, the contact wave and the rarefaction wave to the inflow problem are investigated under some smallness conditions. Note that the amplitude of the rarefaction wave can be arbitrarily large. The proofs are given by the elementary energy method.
Hereditary constitution analysis of Shaolingyuan ancient human in Xi’an, northwestern China  [PDF]
Lin Li, Peihuan Wang, Daiyun Liu, Jinling Shao, Xiaohong Duan
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.58115
Abstract:

In order to identify the kinship of Shaolingyuan ancient human excavated from Shaolingyuan archaeological site with high level of certainty, and infer racial origins more clearly and reliably, this paper analyzed the hereditary constitution of this population. We used the “Reverse root canal technique” to extract ancient DNA from 28 teeth in 28 skeletal remains (3057-2784 BP) of Shaolingyuan archaeological site, obtained the sequences of mtDNA Hypervariable region I (HVR-I) by PCR amplifications; then used MEGA 5.5 software to construct phylogenetic trees and compared the sequences among the sequences of interraces, intraraces. The phylogenetic tree showed that there were two major clusters, Cluster 1 with 16 individuals, and Cluster 2 with 5 individuals. Either the genetic gap or the geographic position of the individuals was small. The frequency of SNP site 16223 T > C was 71.4%, significantly higher than other sites. The comparisons of different population demonstrated that there is no significant difference among them. All of them shared the same haplogroup L1’2’3’4’5’6, close to African. Finally, we confirm that there is a very close genetic relationship between some individuals in this cemetery. We regarded Shao-lingyuan Western Zhou cemetery as a family cemetery, and these people belong to East Asia lineage.
