Based on the random walk and the intentional random walk, we propose two types of immunization strategies which require only local connectivity information. On several typical scale-free networks, we demonstrate that these strategies can lead to the eradication of the epidemic by immunizing a small fraction of the nodes in the networks.Particularly, the immunization strategy based on the intentional random walk is extremely efficient for the assortatively mixed networks.

摘要:水稻生长发育的各个时期都受到高温的威胁,其中以开花期和灌浆期最为敏感,分别导致结实率下降和稻米品质降低。本研究利用大田自然高温,分期播种来源于国内外的19份水稻种质资源,考察不同温度下各供试材料的结实率、精米率、整精米率、垩白粒率、垩白面积、米粒长和米粒宽,分析了它们的结实率以及稻米外观品质与对应温度的相关性,利用72个SSR标记分析了各供试材料间的相似系数,得到如下结果:1.自然高温对供试
