Strengthening the Young College Teachers’ Ideological Political Education Works
Xiaoyan Yang
Asian Social Science , 2010, DOI: 10.5539/ass.v6n2p20
Abstract: Young college teachers’ ideological politics education work with certain particularity is different with students’. Only their ideological politics education work is made well, the talent advantages can be fully exerted, which is very important for the talent cultivation of colleges. Based on the importance of young college students’ ideological politics education work, the problems existing in this work are analyzed and corresponding solutions are proposed in this article.
The Passion behind Serenity
Xiaoyan Yang
Asian Social Science , 2009, DOI: 10.5539/ass.v5n1p119
Abstract: It forms certain sense of beauty in the asymmetry in symmetry, among the shape bodies of oil paintings, between body shape and image as well as the both symmetrical-and-asymmetrical-like objects in the natural world. The structure lines in drawing creation cross each other, are connected with each other and collide with each other, which forms a tense atmosphere, transforms into an instant balance and a kind of comparatively static beauty, and strongly expresses the visual effects and the mood it intends to express.
Dynamics of a Heroin Epidemic Model with Very Population  [PDF]
Xiaoyan Wang, Junyuan Yang, Xuezhi Li
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.26097
Abstract: Based on the model provided by the Mulone and Straughan [1], we relax the population which are constant and obtain the drug-free equilibrium which is global asymptotically stable under some conditions. The system has only uniqueness positive endemic equilibrium which is globally asymptotically stable by using the second compound matrix.
Size Dependence of Dislocation-Mediated Plasticity in Ni Single Crystals: Molecular Dynamics Simulations
Xiaoyan Li,Wei Yang
Journal of Nanomaterials , 2009, DOI: 10.1155/2009/245941
Abstract: We investigate the compressive yielding of Ni single crystals by performing atomistic simulations with the sample diameters in the range of 5 nm ∼ 40 nm. Remarkable effects of sample sizes on the yield strength are observed in the nanopillars with two different orientations. The deformation mechanisms are characterized by massive dislocation activities within a single slip system and a nanoscale deformation twining in an octal slip system. A dislocation dynamics-based model is proposed to interpret the size and temperature effects in single slip-oriented nanopillars by considering the nucleation of incipient dislocations.
Starch grain analysis reveals ancient diet at Kuahuqiao site, Zhejiang Province
XiaoYan Yang,LePing Jiang
Chinese Science Bulletin , 2010, DOI: 10.1007/s11434-009-0545-0
Abstract: Charred residues adhering to sherds of ceramic cooking vessels, pots (Fu), excavated from the Kuahuqiao site (8000–7000 cal a BP) in Zhejiang Province were examined using the method of starch grain analysis. Ancient starch grains were recovered from charred residues and were classified into 8 genera. Remains from rice (Oryza spp.), job’s-tears (Coix chinesis T.), bean (Vigna spp.), acorn (Quercus spp.) as well as possibly buckeye tree (Aesculus chinensis B.) were identified. Other starch grains from unidentified plants were also recovered. Tracheids with bordered pits from softwood fibers were also found, indicating that some food might have been processed with wooden tools. The range of starch grains in the charred residues adhering to the ceramic pots reveals the diversity of ancient plant foods at the Kuahuqiao site, Zhejiang Province.
Method of transforming resistance gene to carbendazim intoTrichoderma sp.
Qian Yang,Xiaoyan Zhao
Chinese Science Bulletin , 1999, DOI: 10.1007/BF03182888
Abstract: The method of transforming resistance gene to carbendazim intoTrichoderma sp. was studied by using genetic engineering technique. The results show that the time of fungicide selection on the transformedTrichoderma sp. may have very important effect on the resistance gene transformation. By this method, the resistance gene to carbendazim was transformed intoTrichoderma harzianum, a strain ofT. harzianum with resistance to carbendazim was achieved. The transformant could grow on the medium containing 150 μg/mL carbendazim. The resistance is stable after 10 times transfer on non-selective medium.
An improved method for measuring the stability of a three-state unfolding protein
XiaoYan Zheng,BinSheng Yang
Chinese Science Bulletin , 2010, DOI: 10.1007/s11434-010-4242-9
Abstract: In the current three-state protein unfolding model, the two transitions are considered to be independent and each transition is fitted to a two-state unfolding model. This three-state unfolding process is therefore composed of two sequential two-state unfolding processes. In this paper, a modified method is presented to determine the value of the unfolding free energy [δG total 0 (H2O)] for the three-state unfolding equilibrium of proteins. This method is demonstrated on the apoCopC protein mutant, Y79W-W83F-Cu, which unfolds via a three-state process. The value of ΔG total 0 (H2O) calculated using the modified method was found to be more accurate in determining ΔG total 0 (H2O) than the previously reported method.
Existence of a Nonautonomous SIR Epidemic Model with Age Structure
Junyuan Yang,Xiaoyan Wang
Advances in Difference Equations , 2010, DOI: 10.1155/2010/212858
Abstract: A nonautonomous SIR epidemic model with age structure is studied. Using integro-differential equation and a fixed point theorem, we prove the existence and uniqueness of a positive solution to this model. We conclude our results and discuss some problems to this model in the future. We simulate our analyzed results.

Semi-Supervised Co-Clustering for Query-Oriented Theme-based Summarization
Libin Yang,Xiaoyan Cai
Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: Sentence clustering plays an important role in theme-based summarization which aims to discover the topical themes defined as the clusters of highly related sentences. However, due to the short length of sentences, the word-vector cosine similarity traditionally used for document clustering is no longer suitable. To alleviate this problem, we regard a word as an independent text object rather than a feature of the sentence and develop a noise detection enhanced co-clustering framework to cluster sentences and words simultaneously. We also explore a semi-supervised clustering approach to make the generated summary biased towards the given query. The evaluation conducted on the three DUC query-oriented summarization datasets demonstrates the effectiveness of the approaches.
