A new method for increasing laser induced damage threshold (LIDT) of dielectric antireflection (AR) coating is proposed. Compared with AR film stack of H2.5L (H:HfO2, L:SiO2 on BK7 substrate, SiO2 interfacial layer with four quarter wavelength optical thickness (QWOT) is deposited on the substrate b

The information diffusion model is a very important factor in study of the.influence maximization problem. This paper contains two notes. The first one is a.simplified proof of Kempe–Kleinberg–Tadös conjecture on general threshold mode1.of social influence. The second one is on the verification of a

1、Python 实现社交网络影响力最大化 Linear_Threshold（线性阈值模型）算法。 2、对线性阈值模型算法进行优化改进，实现贪心算法。 3、代码中有详细注释说明，测试代码，测试节点数据集，并对数据集进行处理，输出测试结果。 4、代码实现环境：Python2.7, Anoconda2,Pycharm2017。
