| 2 | Parameters selection in gene selection using Gaussian kernel support vector machines by genetic algorithm显示文摘In microarray-based cancer classification, gene selection is an important issue owing to the large number of variables and small number of samples as well as its non-linearity. It is difficult to get satisfying results by using conventional linear sta- tistical methods. Recursive feature elimination based on support vector machine (SVM RFE) is an effective algorithm for gene selection and cancer classification, which are integrated into a consistent framework. In this paper, we propose a new method to select parameters of the aforementioned algorithm implemented with Gaussian kernel SVMs as better alternatives to the common practice of selecting the apparently best parameters by using a genetic algorithm to search for a couple of optimal parameter. Fast implementation issues for this method are also discussed for pragmatic reasons. The proposed method was tested on two repre- sentative hereditary breast cancer and acute leukaemia datasets. The experimental results indicate that the proposed method per- forms well in selecting genes and achieves high classification accuracies with these genes. | 毛勇 周晓波 皮道映 孙优贤 WONG Stephen T.C. | 2005 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2005,6,10: | 11 |
| 3 | 在浮选柱工作时平阻板稳定性的研究显示文摘作者过去的工作已证明 ,用平阻板能改善浮选柱指标 ,防止矿浆轴向混合 ,减少泡沫破裂“翻花”现象 ,或防止大气泡的形成。本文提出的示踪物试验结果表明 ,平阻板可提高浮选柱指标的重复性和稳定性。平阻板消除了偶然干扰因素 ,诸如随柱体高度增大而迅速形成的不正常的大气泡和紊流现象。由于这些因素给试验指标造成了很大偏差 ,因而使用平阻板使得浮选柱指标相对稳定 ,短期偏差更小。 | T.C.埃塞尔 谭程鹏 李长根 | 2002 | 国外金属矿选矿2002,39,6: | 7 |

| 6 | 口服低衰减胃肠道造影剂在腹盆部CT中的应用显示文摘Background: We designed and evaluated a low-attenuation oral contrast agent for abdominal-pelvic computed tomography (CT). Methods: In vitro studies, were performed initially to evaluate the imaging characteristics of multiple solutions. These studies resulted in two solutions being compared with the presently accepted oral CT agents of dilute iodinated contrast and water. Ninety-eight consec utive subjects already scheduled for routine outpatient abdominal-pelvic CT were enrolled. Subjects were randomized to water (n = 30), fiber solution (n = 32), polyethylene glycol (PEG; n = 11), or dilute iodinated solution (DI; n = 25). Examinations were then evaluated for gastric distention, small bowel distention, small bowel wall visualization, and colonic transit. A questionnaire was given to the study subjects for feedback concerning taste and potential side effects from these agents. Results: PEG tended to provide better bowel distention, wall visualization, and colonic transit compared with water, fiber solution, and DI. Areas of statistical significance included: (1) average bowel diameter in the left upper quadrant for water was 17.50 mm, whereas that for PEG was 21.88 mm (p < 0.05); (2) average bowel diameter in the pelvis for water was 14.79mm, that for fiber was 15.67mm, and that for PEG was 18.48 mm (p < 0.05); (3) wall visualizati on was better with PEG than with fiber (p < 0.05); (4) successful transit of contrast to the colon occurred in every subject who received PEG compared with only 20%of those received water and 39%of those who received fiber (p < 0.05). Similar trends for the superiority of PEG over DI were noted, although many of these did not reach statistical significance. Conclusion: PEG solution has imaging characteristics related to bowel wall visualization, luminal distention, and colonic transit that make it an effective oral agent for abdominal pelvic CT examination. | Hebert J.J Taylor A.J Winter T.C. 赵双 | 2006 | 世界核心医学期刊文摘(胃肠病学分册)2006,0,4: | 5 |

| 8 | 阴离子聚合制备聚乙烯-g-聚氧化乙烯接枝共聚物显示文摘A new route for synthesis of amphiphilic graft copolymer PE-gPEO containing hydrophobic polyethylene as the backbone and hydrophilic poly(ethylene oxide) a s the side chain has been discussed in this paper.The structure of the copolyme r(such as graft density and graft length),the molecular weights of both polyeth ylene and poly(ethylene oxide) side chain,as well as the molecular weight distr ibution of the copolymer can be designed and controlled easily by this route.Th e molecular weight of poly(ethylene oxide) side chain is proportional to the pol ymerization reaction time and the ethylene oxide monomer concentration,which in dicates the “living' characterization of the anonic polymerization of ethylene oxide.The graft copolymers PE-g-PEO synthesized have been characterized b y 1H-NMR and DSC tests.And the SEM result shows that after adding the amp hiphili c graft copolymer PE-g-PEO as the compatibilizer for the PE/PC polymeric b lend,the compatibility of the blend improved greatly.Therefore,this kind of a mphiphilic graft copolymers can be used as the efficient surfactant for the poly olefin blend and composite materials. | 吕英莹 陈商涛 胡友良 Chung T.C.(Mike) | 2003 | 高分子学报2003,13,3: | 3 |

| 10 | Effect of nitrogen fertilizer on biomass production and nodulation behavior of Pongamia pinnata Pierre seedlings under nursery conditions显示文摘At the seedling stage, a small amount of N is required to boost growth of leguminous plants. A pot experiment was conducted to observe the effect of N fertilizer on various growth parameters and nodulation behavior of Pongamia pinnata under nursery conditions. After the establishment of seedlings, four nitrogen treatments, 0, 40, 80 and 100 kg·ha-1 N were applied in two equal splits. Monthly observations were taken for the morphological parameters viz. plant height, collar diameter, leaf number, root length, root shoot ratio, nodule number and weight per plant. Maximum plant height was recorded after application of N at 40 kg·ha-1 . Seasonally, the difference in collar diameter in rainy season was significantly higher than in winter or summer. However, more leaves were produced per plant at N-40 and N-100 treatments in winter and rainy seasons. Higher root length was recorded in rainy season than in winter or summer. Root biomass was higher than for stems or leaves. Seasonal effects of N-80 and N-40 treatments on leaf dry weight were significantly higher than for N-100 or N-0. Stem dry weight was higher at N-40 than at other treatments in winter and summer seasons. Root:shoot ratio was higher throughout winter to early summer. Nodule biomass was 2-3 times higher in rainy season compared to winter or summer. Maximum nodule number and biomass per plant were highest at N-40, followed by N-0, N-80 and N-100 treatments. New nodule formation started from June to the end of September. Maximum biomass per plant was recorded at N-40, followed by N-80, N-100 and N-0. Nitrogen treatment effect and seasonal behaviour interaction were not significant. Significantly higher numbers of nodules per plant were recorded in rainy season followed by summer and winter for all treatments. Higher nitrogen doses suppressed growth while lower doses promoted growth in Pongamia pinnata. Therefore, the lower nitrogen dose i.e., N-40 Kg·ha-1 applied in two equal splits was suitable at the initial nursery stage for the increase in nodulation and biomass production. | S.P.

| 11 | 粉煤灰作为一种无机球团粘结剂的应用显示文摘尽管粉煤灰利用这一课题的研究被认为已近尾声,我们仍发现还有一大部分粉煤灰未被利用.因此,对粉煤灰的另一全新用途进行了研究,即作为无机矿粉团球的粘结剂,具体的矿粉为铁精矿.经研究发现氧化钙的含量是一个很重要的因素,含钙量高的粉煤灰,如流化床燃烧炉所生成的灰,是一种有效的无机矿粉的粘结剂.含钙量低的粉煤灰也可作为粘结剂,但必需补加氧化钙.该研究也表明,以粉煤灰为基料的粘结剂的性能会因'加速剂',如CaCl2的加入而大大提高. | T.C.爱斯勒 蒋金娥 | 1999 | 国外金属矿选矿1999,36,10: | 2 |
