So it couldn't fit dynamic network environments soundly. After investigating of negative selection, affinity mature and memory detector evolution mechanisms, it is Embedded Negative Selection Operator Clonal Selection Algorithm presented combined with negative selection, clonal selection and memory detector gene library evolution.

Statistic indicates that half of the sepsis is caused by Gram-negative bacteria,and that lipopolysaccharide,which release from the cytoderm of Gram-negative bacteria,is considered to be the major molecule which is responsible for the endotoxin sepsis.

统计表明，临床半数的脓毒症是由于革兰氏阴性菌(Gram-negative bacteria)感染引起的，革兰氏阴性菌的细胞壁上的脂多糖(lipopolysaccharide，LPS)，或称为内毒素，被认为是革兰氏阴性菌引起脓毒症的主要作用分子。

With this notion in mild, we can appreciate the importance of maxillary sinus puncture in documenting microbiology of pediatric rhinosinusitis. By this methodology, we demonstrated that α-hemolytic streptococcus, Hemophilus influenzae, Streptococcus pneumonia, coagulase-negative Staphylococcus, and Staphylococcus aureus are the major organisms found in pediatric rhinosinusitis. We also demonstrate a different pattern of antibiotic resistance when comparing to previous studies performed in both children and adults.

有了这样的概念，便可以知道上颌窦穿刺在儿童鼻及鼻窦炎致病菌培养上的重要性，采用这一方法，我们得到的结果显示小儿慢性鼻及鼻窦炎培养出的主要菌株为α-hemolytic streptococcus，Hemophilus influenzae，Streptococcus pneumonia，coagulase-negative Staphylococcus以及Staphylococcus aureus，除了与成人慢性鼻窦炎的菌株不同外，也显示了与先前类似研究不同的抗生素抗药性形态。

The most common isolates were α-hemolytic streptococcus, Hemophilus influenzae, Streptococcus pneumonia, coagulase-negative Staphylococcus, and Staphylococcus aureus. Anaerobes were recovered from 7.9% of all isolates.

最常见的菌种依序是α-hemolytic streptococcus，Hemophilus influenzae，Streptococcus pneumonia，coagulase-negative Staphylococcus以及Staphylococcus aureus，厌氧菌则占所有菌株的7.9%。

It's very negative to be accused of flip-flopping in U.S.

译：在美国政治上被指责善变是不好的。negative在这里是这么译的吗？

Therefore it is interesting to clone genes related to lemma and palea. In this thesis, six genes from the lemma/palea related gene pool which is established by Liu (2003) were further studied. Those genes are salT gene (salt-induced protein), GA-SPY gene (gibberellin action negative regulator SPY-related protein), U2AF gene (U2 snRNP auxiliary factor, small subunit-related protein), kinesin-like gene, DnaJ-like gene, and EF hand gene. At first, the gene expression in leaves and 1~4 cm inflorescences of normal lemma/palea, smaller lemma/palea, and stunted lemma/palea was compared by Real Time RT-PCR.

从刘(2003)所建立水稻颖花发育相关候选基因库中，挑选6个基因：salT基因(salt-induced protein)、GA-SPY基因(gibberellin action negative regulator SPY-related protein)、U2AF基因(U2 snRNP auxiliary factor，small subunit-related protein)、kinesin-like基因、DnaJ-like基因、及EF hand基因，以水稻正常型颖花、小颖花突变体及内外颖退化突变体之叶片及1~4公分幼花序为材料，利用Real-Time RT-PCR分析，发现salT基因在突变体幼花序中大量表现。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
