An overview of our research group’s experimental and theoretical developments is provided on the linear and nonlinear optical effects of white light since 2003. Their work includes the experimental researches on the white light one-dimensional photovoltaic dark spatial solitons and the waveguides and directional couplers induced by them, the circular and elliptic white-light dark spatial solitons and the white-light photorefractive phase masks, two-dimensional white-light photonic lattices and the applications of the white-light dark spatial solitons in the digital image transmission field, the interaction between the two-dimensional white-light dark spatial solitons to enhance or to improve the correlated degree of the white light through the interaction between the white-light beam and coherent dark spatial solitons, the interaction between the one- or two-dimensional white-light dark spatial solitons and the two-dimensional white-light photonic lattices, respectively. We also numerically simulate the interaction between two or more partially incoherent bright spatial solitons and the white bright spatial soliton pairs in the saturated logarithmic nonlinear medium. We have observed experimentally for the first time, the modulation instability of the coherent light and white light, respectively, in self-defocusing medium and so on.

Differential expression of the TwHMGS gene and its effect on triptolide biosynthesis in Tripterygium wilfordii

Chinese Journal of Natural Medicines 2019年第8期17卷 575-584页

作者： TONG Yu-ru ZHANG yi-Feng ZHAO Yu-Jun HU Tian-Yuan WANG Jia-Dian huang Lu-Qi GAO Wei School of Pharmacy Traditional Chinese Materia Medica Shenyang Pharmaceutical University Shenyang 110016 China National Resource Center for Chinese Materia Medica China Academy of Chinese Medical Sciences Beijing 100700 China School of Pharmaceutical Science Capital Medical University Beijing 100069 China School of Traditional Chinese Medicine Capital Medical University Beijing 100069 China Advanced Innovation Center for Human Brain Protection Capital Medical University Beijing 100069 China

3-Hydroxy-3-methylglutaryl-CoA synthase(HMGS) is the first committed enzyme in the MVA pathway and involved in the biosynthesis of terpenes in Tripterygium wilfordii. The full-length cDNA and a 515 bp RNAi target fragment of TwHMGS were ligated into the p H7 WG2 D and p K7 GWIWG2 D vectors to respectively overexpress and silence, Tw HMGS was overexpressed and silenced in T. wilfordii suspension cells using biolistic-gun mediated transformation, which resulted in 2-fold increase and a drop to70% in the expression level compared to cells with empty vector controls. During Tw HMGS overexpression, the expression of TwHMGR, TwDXR and TwTPS7 v2 was significantly upregulated to the control. In the RNAi group, the expression of Tw HMGR,TwDXS, TwDXR and TwMCT visibly displayed downregulation to the control. The cells with TwHMGS overexpressed produced twice higher than the control value. These results proved that differential expression of Tw HMGS determined the production of triptolide in *** and laterally caused different trends of relative gene expression in the terpene biosynthetic pathway. Finally, the substrate acetyl-Co A was docked into the active site of TwHMGS, suggesting the key residues including His247, Lys256 and Arg296 undergo electrostatic or H-bond interactions with acetyl-CoA.

TAILORED FINITE CELL METHOD FOR SOLVING HELMHOLTZ EQUATION IN LAYERED HETEROGENEOUS MEDIUM

引用

Journal of Computational Mathematics 2012年第4期30卷 381-391页

作者： Zhong-yi huang Xu Yang Department of Mathematical Sciences Tsinghua University Beijing 100084 China Department of Mathematics Courant Institute of Mathematical Sciences New York UniversityNew York NY 10012 USA

In this paper, we propose a tailored finite cell method for the computation of two- dimensional Helmholtz equation in layered heterogeneous medium. The idea underlying the method is to construct a numerical scheme based on a local approximation of the solution to Helmholtz equation. This provides a computational tool of achieving high accuracy with coarse mesh even for large wave number （high frequency）. The stability analysis and error estimates of this method are also proved. We present several numerical results to show its efficiency and accuracy.

Structured AJAX Data Extraction Based on Agricultural Ontology

Journal of Integrative Agriculture 2012年第5期11卷 784-791页

More web pages are widely applying AJAX （Asynchronous JavaScript XML） due to the rich interactivity and incremental communication. By observing, it is found that the AJAX contents, which could not be seen by traditional crawler, are well-structured and belong to one specific domain generally. Extracting the structured data from AJAX contents and annotating its semantic are very significant for further applications. In this paper, a structured AJAX data extraction method for agricultural domain based on agricultural ontology was proposed. Firstly, Crawljax, an open AJAX crawling tool, was overridden to explore and retrieve the AJAX contents; secondly, the retrieved contents were partitioned into items and then classified by combining with agricultural ontology. HTML tags and punctuations were used to segment the retrieved contents into entity items. Finally, the entity items were clustered and the semantic annotation was assigned to clustering results according to agricultural ontology. By experimental evaluation, the proposed approach was proved effectively in resource exploring, entity extraction, and semantic annotation.

Acta Mathematica Sinica,English Series 2018年第12期34卷 1879-1891页

Let T ： X →X be a continuous map of a compact metric space X. A point x E X is called Banach recurrent point if for all neighborhood V of x, （n ∈ N ： T^n（x） ∈ V} has positive upper Banach density. Denote by Tr（T）, W（T）, QW（T） and BR（T） the sets of transitive points, weakly almost periodic points, quasi-weakly almost periodic points and Banach recurrent points of （X, T）. If （X, T） has the specification property, then we show that every transitive point is Banach recurrent and O≠ W（T） n Tr（T） ≠ W＊（T） ∩ Tr（T） ≠ QW（T） ∩ Tr（T） ≠ BR（T） ∩ Tr（T）, in which W＊（T） is a recurrent points set related to an open question posed by Zhou and Feng. Specifically the set Tr（T） M W＊（T）／ W（T） is residual in X. Moreover, we construct a point x E BR ／ QW in symbol dynamical system, and demonstrate that the sets W（T）, QW（T） and BR（T） of a dynamical system are all Borel sets.
