Generalized discriminant analysis （GDA） is a nonlinear extension of the classical linear discriminant analysis （LDA） via kernel *** a feature extraction method,it has been proven successful in many applications such as radar high-range-resolution profiles （HRRP） ***,GDA often suffers from the so-called small sample size problem （SSS） which exists in high-dimensional pattern recognition *** overcome this weakness,we present a new algorithm for solving GDA by utilizing the idea of direct-LDA （DLDA） in this *** based on three measured airplanes data are conducted to evaluate the effectiveness of the proposed *** the results we can see that the new algorithm is more transparent and easier to be implemented than the traditional one,while keeping competitive classification accuracy.

Refractive Index Change and Color Center Formation in LiYF_4 Crystal Induced by a Femtosecond Laser

全国中青年中西医结合学术（英语）交流会议

Why does not the modern drug targeting the specificity of disease produce the theoretical effect in clinical observation? The reason is that the non-specificity of disease sometimes influences the therapeutic effect. Why does not the Chinese herbal medicine targeting the Zheng produce the theoretical effect in clinic? The reason is that the Zheng does not target all specificity of disease and only target the non-specificity and part of the specificity. Thus, Zheng should have some impacts on the pathogenesis of disease, and the differentiation of Zheng need to refer the diagnosis of disease.

Carcinogenic potential of duodenal reflux juice from patients with long-standing postgastrectomy

Third East Asian Polymer Conference

作者： Zhengping Liu Hongyu Zhao Institute of Applied Chemistry, Department of Chemistry, Beijing Normal University Beijing 100875, tel. 86-10-62206896, Fax: 86-10-62202075

Polymer electroluminescent derivates have attracted great interest due to advantages of conjugated-polymer-based LED over small-molecule-based LED, for example, low cost, large area, flexibility, light weight, and easy design of the molecular structure. Among the conjugated polymers, poly(p-phenylene vinylene) (PPV) is one of the most promising materials for the application of polymer LEDs. The Gilch route offer a few advantages including mild reaction conditions, low polydispersity, high molecular weight, and easy purification. So, the Gilch route is the most common method.

AIM: To determine whether study on the carcinogenic potential of reflux juice from patients with remote gastrectomy could clarify the inherent relationship between duodenal reflux and gastric stump cancer. METHODS: A total of 37 reflux juice samples (13 Billroth I, 24 Billroth II) were employed in the present study. A two-stage transformation assay using BALB/c 3T3 cells was carried out to test the initiating or promoting activity of these samples. RESULTS: Two of 18 (11.1%) reflux samples exerted initiating activities, whereas 9/19 (47.4%) samples enhanced the MNNG-initiating cell transformation, suggesting the duodenal reflux juice might more frequently possess the tumor-promoter activity (P = 0.029). In addition, there was no difference in initiating activities of the samples irrespective of surgical procedures (P = 0.488), while Billroth II samples exhibited stronger tumor-promoter activity than Billroth I samples (P = 0.027). Furthermore, the promoter activities were well correlated with the histological changes of the stomas (r(s) = 0.625, P = 0.004), but neither their cytotoxicities nor initiating activities had this correlation (Probabilities were 0.523 and 0.085, respectively). CONCLUSION: The duodenal reflux juice from patients with remote postgastrectomy did have carcinogenic potential, and suggested that tumor-promoting activity should principally account for the high incidence of gastric cancer in gastrectomy patients. In contrast, it is difficult to explain the high stump-cancer incidence with the N-nitroso compounds theory-a popular theory for the intact stomach carcinogenesis, and it seemed to be justified to focus chemo-prevention of this cancer on the tumor-promoting potential of reflux juice.

在定向井、丛式井、水平井钻井中，对待钻井眼方位变化的预测，一直是个重要的问题，它直接影响到待钻井眼的设计，井下工具的准备、选择，影响到下部井段是否能顺利施工。为此，运用钻具力学分析和地层各向异性理论的研究成果，综合考虑上部井眼或邻井的实钻情况和地层产状要素等，利用钻具与岩层间的空间位置关系计算钻头的位移量，从而定量地推导出了待钻井眼方位变化率计算式，通过对川西南隆４０－１大斜度定向井的计算和川中莲池５０水平井的预测，其效果是满意的，与实钻情况相符。

The Quasi-phase-matching periodically poled flux-grown KTP by high electrical field method is researched. A 8×5×1mm3,∧=9.0μm PPKTP wafer is successfully fabricated for the first order QPM SHG. The interactive length of the sample is about 3mm. The SHG scheme of Nd: YAG at 1064nm tested that the output power of cw 532nm green light is 0.2mw at room temperature with fundamental power of 1.2w. The normalized conversion efficiency is about 0.09% (W·cm)-1.
