Activation-induced cytidine deaminase(AID)is required for the generation of antibody diversity through initiat-ing both somatic hypermutation(SHM)and class switch recombination.A few research groups have success-fully used the feature of AID for generating mutant li-braries in directed evolution of target proteins in B cells in vitro.B cells,cultured in suspension,are not con-venient for transfection and *** this study,we established an AID-based mutant accumulation and sorting system in adherent human *** AID gene was first transfected into the human non-small cell lung carcinoma H1299 cells,and a stable cell clone(H1299-AID)was ***,anti-hTNF-αscFv(ATscFv)was transfected into H1299-AID cells and ATscFv was displayed on the surface of H1299-AID *** 4-round amplification/flow cytometric sorting for cells with the highest affinities to hTNF-alpha,two ATscFv mutant gene clones were *** with the wild type ATscFv,the two mutants were much more efficient in neutralizing cytotoxicity of *** results indicate that directed evolution by somatic hypermutation can be carried out in adherent non-B cells,which makes directed evolution in mammalian cells easier and more efficient.

在保证一定的覆盖质量前提下,延长传感器网络生存时间,提出一种以充分必要条件判断网络节点冗余性的分布式覆盖控制协议.该协议通过多重交点判别法则(MIER,Multi-Intersection Estimation Rule)对无线传感器网络进行分布式节点的动态休眠控制,从理论上证明了MIER法则是判断网络节点冗余性的充分必要条件,能保证目标区域不出现覆盖盲点同时使活跃节点数降至最低.实验表明,MIER法则比CCP法则有了很大改进,消除由于法则本身引起的盲点数目,能更好的运用于覆盖控制协议中,更为准确的判断节点是否应该工作或休眠,是判别节点是否冗余的充分必要条件;同时比Ottawa法则更加高效的减少整个网络功耗,延长网络寿命.

降低功耗、延长寿命是无线传感器网络的一个重要问题,同时,对监测区域保持一定的覆盖质量才能及时捕捉到目标的状态变化.一种广泛采用的策略是选出能够满足监测区域质量要求的最小节点集作为工作节点,关闭其他冗余节点.因此,传感器网络中控制节点休眠与保持覆盖质量是两个重要方面.提出了一个数学模型,求解满足任意给定覆盖服务质量下所需的最小节点数.实验表明,当监测区域与节点感知区域比值较大时,提出的方法更为准确地计算出所需最小工作节点数,且此方法复杂度低、传感器节点的感知区域可以为任意形状.网络覆盖质量与节点休眠率同时达到最大化是一个NP难问题,采用遗传算法进行仿真实验尝试性解决这一问题,为传感器网络实际应用带来重要意义.
