  1. At the first step of the algorithm, based on the theory of principal component analysis, a modified principal component analysis ( mpca ) approach is adopted to reduce the dimension of data horizontally, then after comparing existing clustering algorithms, an immune clustering algorithm is put forward based on similarity measurement of principle component core for vertical reduction by using related mechanism of clone selection as well as immune network self - stabilization in natural organic immune system for reference

    在進行樣本參量的降維處理時,基於主元分析的思想,採用一種改進的主元分析( mpca )方法用於橫向數據壓縮,在壓縮樣本數量時,綜述和比較了現有的各種聚類演算法,借鑒生物體自然免疫系統中克隆選擇以及免疫網路自穩定等有關機理,提出了基於主元核相似度的免疫聚類演算法用於縱向數據壓縮。
  2. This expression vector plbcas - hsa - lgl has the following advantages : i ) the 1. 7kb promoter is able to drive cell - specific and hormone - dependent expression ; ii ) the inclusion of intron - 1 can increase expression level of fusion genes ; iii ) the 5 ' utr of bovine p - casein mrna may have a positive role in both transcriptional and post - transcriptional regulation ; iv ) the gfp gene make the selection of positive clone among embryos possible ; v ) the gfp gene can be easily excised via cre - mediated recombination between the two loxp sites after the expression vector has been integrated into chromosome ; vi ) the two incompatible lox sites, loxp and lox2272, would facilitate cre - recombinase mediated cassette exchange ( rmce ), which in theory will leading to develop a technology of site - specific gene expression in animal mammary glands

    該載體的特點是:具有可以調控外源基因在乳腺中特異表達的牛-酪蛋白基因5 `端側翼區和包括第一外顯子及內含子在內的5 `端調控區;將人血清白蛋白cdna準確地置於牛-酪蛋白基因第二外顯子中的翻譯起始密碼子atg之後,而且沒有增加額外的序列和使人血清白蛋白cdna移碼;引入標記基因gfp ,便於在胚胎期鑒定陽性胚胎,減少受體;引入cre lox重組系統: ( ? )標記基因gfp的兩端的兩個loxp位點可以在表達載體整合到基因組后,刪除標記基因; ( ? )餘下的一個loxp位點可以和前面的lox2272位點組成cre重組酶介導的盒式交換系統。
  3. The content of this paper includes : the clonal selection theory in ais and the application of the clone operator are present in detail in this paper. based on the analysis of the bottleneck of the evolutionary algorithm, the quantum clonal evolutionary algorithm is presented

    給出了克隆運算元的具體實現方法; ( 2 )在分析進化演算法的不足和瓶頸問題后,提出了量子克隆進化計算的理論框架,其中包括:量子克隆遺傳演算法、量子克隆進化策略、量子克隆進化規劃。
