Multiallelic epistatic model for an out-bred cross and mapping algorithm of interactive quantitative trait loci
Chunfa Tong, Bo Zhang, Zhong Wang, Meng Xu, Xiaoming Pang, Jingna Si, Minren Huang, Rongling Wu
BMC Plant Biology , 2011, DOI: 10.1186/1471-2229-11-148
Abstract: Here we have formulated a general framework to model and define the epistasis between multiallelic QTLs. Based on this framework, we have derived a statistical algorithm for the estimation and test of multiallelic epistasis between different QTLs in a full-sib family of outcrossing species. We used this algorithm to genomewide scan for the distribution of mul-tiallelic epistasis for a rooting ability trait in an outbred cross derived from two heterozygous poplar trees. The results from simulation studies indicate that the positions and effects of multiallelic QTLs can well be estimated with a modest sample and heritability.The model and algorithm developed provide a useful tool for better characterizing the genetic control of complex traits in a heterozygous family derived from outcrossing species, such as forest trees, and thus fill a gap that occurs in genetic mapping of this group of important but underrepresented species.Approaches for quantitative trait locus (QTL) mapping were developed originally for experimental crosses, such as the backcross, double haploid, RILs or F2, derived from inbred lines [1-3]. Because of the homozygosity of inbred lines, the Mendelian (co)segregation of all markers each with two alternative alleles in such crosses can be observed directly. In practice, there is also a group of species of great economical and environmental importance - out-crossing species, such as forest trees, in which traditional QTL mapping approaches cannot be appropriately used. For these species, it is difficult or impossible to generate inbred lines due to long generation intervals and high heterozygosity [4], although experimental hybrids have been commercially used in practical breeding programs.For a given outbred line, some markers may be heterozygous, whereas others may be homozygous over the genome. All markers may, or may not, have the same allele system between any two outbred lines used for a cross. Also, for a pair of heterozygous loci, their allel

Qiuling He, Ye Shen, Mingxiu Wang, Minren Huang, Ruizhen Yang, Shuijin Zhu, Liangsheng Wang, Yanjun Xu, Rongling Wu
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0022098
Abstract: Lycoris longituba is one of the species belonging to the Amaryllidaceae family. Despite its limited distribution, endemic to central eastern China, this species displays an exceptionally wide diversity of flower colors from purple, red, orange, to yellow, in nature. We study the natural variation of floral color in L. longituba by testing the components of water-soluble vacuolar pigments – anthocyanins – in its petals using high-performance liquid chromatography coupled with photodiode array detection and electrospray ionization mass spectrometry. Four anthocyanins were identified, cyanidin-3-sophoroside (Cy3So), cyanidin-3-xylosylglucoside (Cy3XyGlc), cyanidin-3-sambubioside (Cy3Sa), and pelargonidin-3-xylosylglucoside (Pg3XyGlc), which occur at various amounts in L. longituba petals of different colors. A multivariate analysis was used to explore the relationship between pigments and flower color. Anthocyanins have been thought to play a major role in acting as a UV screen that protects the plant's DNA from sunlight damage and attracting insects for the purpose of pollination. Thus, knowledge about the content and type of anthocyanins determining the petal coloration of Lycoris longituba will help to study the adaptive evolution of flowers and provide useful information for the ornamental breeding of this species.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.4599.4602
Abstract: Brain-Derived Neurotrophic Factor (BDNF) is a member of the neurotrophin family of growth factors and plays significant role in central nervous system and the peripheral nervous system for supporting the survival of existing neurons and encouraging the growth and differentiation of new neurons and synapses. Increasing study indicate that BDNF is associated with neurological disorders and psychiatric diseases. Beyond the importance of BDNF in nervous system, compelling evidence also demonstrate that it is also essential for body weight control and energy homeostasis. BDNF therefore, become the target in various diseases research such as Alzheimer s disease, depressive disorder and obesity. In this study, researchers cloned the BDNF gene to p-EGFP N1 expression plasmid, meanwhile, researchers also transfected the p-EGFP N1-BDNF to Hela cell with lipofection. Fluorescence microscope and Western blot analysis showed BDNF could normally express in Hela cell. However, the physiological functions and pharmacological roles of the p-EGFP N1-BDNF need further validation in cellular level and animal model.

A Real-Time Transient Analysis of a Functionally Graded Material Plate Using Reduced-Basis Methods  [PDF]
Yonghui Huang, Yi Huang
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2015, DOI: 10.4236/alamt.2015.53010
Abstract: Based on the hybrid numerical method (HNM) combining with a reduced-basis method (RBM), the real-time transient response of a functionally graded material (FGM) plates is obtained. The large eigenvalue problem in wavenumber domain has been solved through real-time off-line/on-line calculation. At off-line stage, a reduced-basis space is constructed in sample wavenumbers according to the solved eigenvalue problems. The matrices independent of parameters are projected onto the reduced-basis spaces. At on-line stage, the reduced eigenvalue problems of the arbitrary wavenumbers are built. Subsequently, the responses in wavenumber domain are obtained by the approximated eigen-pairs. Because of the application of RBM, the computational cost of transient displacement analysis of FGM plate is decreased significantly, while the accuracy of the solution and the physics of the structure are still retained. The efficiency and validity of the proposed method are demonstrated through a numerical example.
Adaptive Reduced Basis Methods Applied to Structural Dynamic Analysis  [PDF]
Yonghui Huang, Yi Huang
American Journal of Computational Mathematics (AJCM) , 2015, DOI: 10.4236/ajcm.2015.53029
Abstract: The reduced basis methods (RBM) have been demonstrated as a promising numerical technique for statics problems and are extended to structural dynamic problems in this paper. Direct step-by-step integration and mode superposition are the most widely used methods in the field of the finite element analysis of structural dynamic response and solid mechanics. Herein these two methods are both transformed into reduced forms according to the proposed reduced basis methods. To generate a reduced surrogate model with small size, a greedy algorithm is suggested to construct sample set and reduced basis space adaptively in a prescribed training parameter space. For mode superposition method, the reduced basis space comprises the truncated eigenvectors from generalized eigenvalue problem associated with selected sample parameters. The reduced generalized eigenvalue problem is obtained by the projection of original generalized eigenvalue problem onto the reduced basis space. In the situation of direct integration, the solutions of the original increment formulation corresponding to the sample set are extracted to construct the reduced basis space. The reduced increment formulation is formed by the same method as mode superposition method. Numerical example is given in Section 5 to validate the efficiency of the presented reduced basis methods for structural dynamic problems.

—Analysis of English Public Opinion in Southeast and South Asia

Yanyao Huang, Lei Huang
Chinese Studies (ChnStd) , 2017, DOI: 10.4236/chnstd.2017.63014
Abstract: Being an important political event, the National People’s Congress and the Chinese Political Consultative Conference (also known as “Two Sessions”) have drawn attention worldwide. Since neighboring China and playing significant roles in Chinese “the Belt and Road” initiative, countries in Southeast and South Asia have delivered reports specifically about heating issues over “Two Sessions”. The overall features of public opinion are as follow: 1) the number of reports increases as time passes; 2) reporting focuses lie mainly on economic and political fields and factual reports account for more than half of the whole coverage; 3) national differences exist in reporting focuses, accompanied by prominent nationally public opinion tendencies; 4) domestic media diversify with one and another about focuses of coverage. After research, this paper suggests that, to improve its power of discourse in international public opinion, China should strengthen its publication with English media by keeping an eye on public opinion tendency as well as standpoint of diversified media overseas.
On Twisted Virasoro Operators and Number Theory
An Huang
Physics , 2009,
Abstract: We explore some axioms of divergent series and their relations with conformal field theory. As a consequence we obtain another way of calculating $L(0,\chi)$ and $L(-1,\chi)$ for $\chi$ being a Dirichlet character. We hope this discussion is also of interest to physicists doing renormalization theory for a reason indicated in the Introduction section. We introduce a twist of the oscillator representation of the Virasoro algebra by a group of Dirichlet characters and use this to give a 'physical interpretation' of why the values of certain divergent series should be given by special L values. Furthermore, we use this to show that some fractional powers which are crucial for some infinite products to have peculiar modular transformation properties are expressed explicitly by certain linear combinations of $L(-1, \chi)$'s for appropriately chosen $\chi$'s, and can be understood physically as a kind of 'vacuum Casimir engergy' in our settings. We also note a relation between field theory and our twisted operators. Lastly we give an attempt to reinterpret Tate's thesis by a sort of conformal field theory on a number field.
