查询词典 natural selection

Preprocessing consists of data selection, baseline adjustment, noise filtering and peak identification. Data selection removes preprimer data section which contains little useful information. Baseline adjustment adjusts the baselines of four channels to the same level. Noise filtering removes the impulse noise and white noise. Peak identification selects the peak data for use in cross matrix determination.

To obtain efficient survivability, this paper presents a novel restorable lightpath selection algorithm based on the automatically switched optical network frame. A numerical simulation is made in term of this routing selection algorithm. The result shows that the traffic has an obvious balancing trend; the block probability of connection requests has been reduced. At the same time, this algorithm has an excellent performance on bandwidth utility and sharing of the restoration resources.

The efficiency of selection was monitored by comparing the number of phage recovered from the acid elution and cell lysate in each round,and by testing EGFR binding specificity of polyclonal phagescFv on CHOEGFRGFP1 and CHOK1 cell with cell ELISA. Bacterial PCR was used to select clones containing a 1 kb insert. Cell ELISA was used to determine EGFR binding specificity of monoclonal pscFv on EGFR positive and negative cell. The number of individual EGFRbinding clones was determined with nucleotide sequencing. Results 500fold enrichments were observed by tittering phages in the cell lysate after five rounds of selection.

Results 500fold enrichments were observed by tittering phages in the cell lysate after five rounds of selection. A signal significantly greater than background binding was observed from the third to the fifth round of selection on CHOEGFRGFP1 and CHOK1 cell, but a part of polyclonal scFv bound EGFR specially. About 45% of the selected clones contained a fullsized insert of 1 kb. One unique human antiEGFR scFv (F4scFv) was isolated by analyzing with cell ELISA and DNA sequencing.

结果 经过5轮筛选，细胞裂解液中洗脱出噬菌体效价有500倍以上增长；细胞ELISA结果显示多克隆pscFv与CHOEGFRGFP1细胞和CHOK1细胞均有明显结合，但有部分特异性结合EGFR；菌落PCR显示约45％克隆中含有完整的1kb scFv片断；经细胞ELISA、 DNA测序检测共获得1株EGFR特异性单链抗体，命名为F4scFv。

In this paper, we have proposed a flexible encryption blocks selection buyer-seller watermarking protocol integrated the RSA asymmetric encryption system and homomorphism mechanism to protect the ownership of digital contents and fit real life. And consider the secondhand transaction in the real life. We also propose a buyer-reseller watermarking protocol based on the flexible encrypt blocks selection buyer-seller watermarking protocol to offer a solution of secondhand transaction. In our scheme, it's more light data transport requirement than other schemes. All roles in protocol will benefit by their participation. Our scheme can overcome various of the known attacks and security problems in the buyer-seller watermark protocol, such as buyer's right problem, unbinding problem, piracy tracing problem, conspiracy problem, buyer's participation in the dispute resolution problem, man-in-the-middle attack problem and anonymous problem. Furthermore, the seller and arbiter can verify the buyer's watermark without decrypting it in our scheme.
