NATURAL LANGUAGE SEMANTICS PROCESSING-CASE IDENTIFYING BASED ON MEANING RELATION
Bo, Wang Jian,Zhu, Wang Kai,Yue, Ma,Zhou, Zhou Jing 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
Natural language semantics is the key problem in natural language processing. Information used to analyse natural language semantics comes from several sides. We study meaning relation inter text, paragraph and sehtence, and propose a method to determine setence meaning. Basing on them, we implement a news report understanding system. In our system, meaning representation is in semantic network form based on case relation. Depending on meaning relation, a candidate eliminating method to identify case relation is developed. For each nominal chunk (NC), it can play several case roles. These case roles are NC's case candidates in a sentence. Improper case candidates are eliminated and the proper one is choosed as case role in the sentence.

Glyphosate is the active component of the top-selling herbicide, the phytotoxicity of which is due to its inhibition of the shikimic acid pathway. 5-Enolpyruvylshikimate-3-phosphate synthase (EPSPS) is a key enzyme in the shikimic acid pathway. Glyphosate tolerance in plants can be achieved by the expression of a glyphosate-insensitive aroA gene (EPSPS). In this study, we used a PCR-based two-step DNA synthesis method to synthesize a new aroA gene (aroAR. leguminosarum) from Rhizobium leguminosarum. In vitro glyphosate sensitivity assays showed that aroAR. leguminosarum is glyphosate tolerant. The new gene was then expressed in E. coli and key kinetic values of the purified enzyme were determined. Furthermore, we transformed the aroA gene into Arabidopsis thaliana by the floral dip method. Transgenic Arabidopsis with the aroAR. leguminosarum gene was obtained to prove its potential use in developing glyphosate-resistant crops.

Laccases can oxidize a variety of phenolic and non-phenolic substrates including synthetic dyes. In this research, a laccase gene Lcc9 from Laccaria bicolor was chemically synthesized and optimized to heterogeneous expression in Pichia pastoris and Arabidopsis thaliana. The properties of recombinant laccase expressed by P. pastoris were investigated. The laccase activity was optimal at 3.6 pH and 40°C. It exhibited K<sub>m</sub> and V<sub>max</sub> values of 0.565 mmol l<sup>-1</sup> and 1.51 μmol l<sup>-1</sup> min<sup>-1</sup> for ABTS respectively. As compared with untransformed control plants, the laccase activity in crude extracts of transgenic lines exhibited a 5.4 to 12.4-fold increase. Both laccases expressed in transgenic P. pastoris or A. thaliana could decolorize crystal violet. These results indicated that L. bicolor laccase gene may be transgenically exploited in fungi or plants for dye decolorization.

In beer, glutathione works as the main antioxidant compound, which also correlates with the stability of the beer flavor. In addition, high residual sugars in beer contribute to major nonvolatile components, which are reflected in a high caloric content. Therefore, in this study, the Saccharomyces cerevisiae GSH1 gene encoding glutamylcysteine synthetase and the Saccharomycopsis fibuligera ALP1 gene encoding α-amylase were coexpressed in industrial brewing yeast strain Y31 targeting the α- acetolactate synthase (AHAS) gene (ILV2) and alcohol dehydrogenase gene (ADH2), resulting in the new recombinant strain TY3. The glutathione content in the fermentation broth of TY3 increased to 43.83 mg/l as compared with 33.34 mg/l in the fermentation broth of Y31. The recombinant strain showed a high α-amylase activity and utilized more than 46% of the starch as the sole carbon source after 5 days. European Brewery Convention tube fermentation tests comparing the fermentation broths of TY3 and Y31 showed that the flavor stability index for TY3 was 1.3-fold higher, whereas its residual sugar concentration was 76.8% lower. Owing to the interruption of the ILV2 gene and ADH2 gene, the contents of diacetyl and acetaldehyde as off-flavor compounds were reduced by 56.93% and 31.25%, respectively, when compared with the contents in the Y31 fermentation broth. In addition, since no drug-resistant genes were introduced to the new recombinant strain, it should be more suitable for use in the beer industry, owing to its better flavor stability and other beneficial characteristics.

Mountain Tai Shadow Play is kind of folk art originated in the area around Mountain Tai in Shandong Province. In June 2008, it was packed with the other 11 kinds of shadow plays, such as Beijing Shadow Play, Hejian Shadow Play and Xiuyan Shadow Play, etc. into one cultural item namely "Shadow Play" and entered the first batch of the Expanded Inventory of National Intangible Cultural Heritage. (NO, IV-91) Against the fact that this art is dying, there is very rare research about it yet. From Dec. 2007, I started to know the only inheritor of this art Mr. Fan ZhengAn and did interviews with him for a few times, which is the basis of this paper. This paer tries to demonstrate the uniqueness of this tradition through working on the following three aspects: Firstly, to define the historical evolution, the main characteristics as well as the contemporary living status of Mountain Tai Shadow Play under the local context; Secondly, to explore the training process of an apprentice to become a qualified artist; thirdly. to argue that the tradition of Mountain Tai Shadow keeps growing rather than perishing through a dynamic mechanism of innovation and the ardent efforts of the artist.

Substructure pseudo-dynamic hybrid simulation (SPDHS) is an advanced structural seismic testing method which combines physical experiment and numerical simulation. Generally, the key components which display nonlinearity first are taken as experimental substructures for actual test, and the remaining parts are modeled in simulation. Model updating techniques can be effectively applied to enhance the model precision of nonlinear numerical elements. Specifically, the constitutive model of the experimental substructure is identified online by the instantaneously-measured data, and the corresponding numerical elements with similar hysteretic behaviors are updated synchronously. Artificial neural network (ANN) can recognize the system which cannot be represented by definite numerical model, and thus avoids the structural response distortion caused by the inherent numerical model defects. In this study, a framework for online model updating in SPDHS with ANN method is expanded to implement actual test validation. Moreover, the effectiveness of ANN method is demonstrated by practical tests of a two-story frame model with bending dampers. Additionally, the unscented Kalman filter technique and offline ANN identification approach are both examined in the test validation. The experimental results show that, under the identical loading history, the online ANN method can significantly reduce the model errors and improve the accuracy of SPDHS.

Sybil attack has been proved effective in mitigating the P2P botnet, but the impacts of some important parameters were not studied, and no model to estimate the effectiveness was proposed. In this paper, taking Kademlia-based botnets as the example, the model which has the upper and lower bound to estimate the mitigating performance of the Sybil attack is proposed. Through simulation, how three important factors affect the performance of the Sybil attack is analyzed, which is proved consistent with the model. The simulation results not only confirm that for P2P botnets in large scale, the Sybil attack is an effective countermeasure, but also imply that the model can give suggestions for the deployment of Sybil nodes to get the ideal performance in mitigating the P2P botnet.
