量化复杂网络之间的结构相似性是网络科学中一个基本且具有挑战性的问题,在医学、社会学等多个领域发挥了至关重要的作用.传统的网络比较方法通常基于简单的结构特征,例如节点度分布、最短路径长度等,这些方法可能无法充分捕捉网络的全局结构信息,导致得到的网络相似性不精准.本文提出了一种基于高阶信息的网络相似性比较方法,该方法同时考虑了网络的全局结构和局部结构.具体而言,通过构建网络节点的高阶聚类系数分布和节点间距离分布,并利用基于这两个分布的Jensen-Shannon散度来量化网络之间的相似性.实验结果表明,相较于其他基线方法,本文提出的方法不仅能高效地比较不同网络的相似性,且在对真实网络进行扰动的过程中也表现出鲁棒性.

艺术的本质问题是一个论争了几个乃至十几个世纪的话题,也是一个曾经被“反本质主义”要放弃和搁置讨论的形而上问题。从历史上看,研究者曾从“模仿”“形式”“表现”来界定艺术的本质。可以说,艺术既是对现实的“模仿”,又不完全是,因为“模仿”的目的是要表达作者的情感和感受。艺术既是要创造一种美的“形式”,又不完全是,因为通过美的“形式”也还是要表达作者的艺术追求和主观感受。因此,无论“模仿说”还是“形式说”,最终的目的都是要表达或表现作者的主观感觉。“表现”才是艺术中最主要和最核心的元素,“表现说”也更充分地体现着艺术的本质。

基因编辑技术以其革命性对人类生活产生了诸多方面的深远影响,但其风险性也让人们心生恐惧,为此,必须为基因编辑技术划定研究与应用的界限。具体界限可以从人们的伦理批判性思考中得到有力的诠释。或许可以说,人们对生命、责任、力量等方面的伦理认知在一定程度上成为划定界限的依据。由此而言,基于技术与伦理内在关联性的维度,基因编辑技术能够得到健康有序的发展。所以,对于有效规制基因编辑技术的发展来说,伦理方面的相关举措非常重要。我们需要从理论智慧、制度完善、个体践行等方面,通过多方主体的协同努力,积极引导人们形成适合时代发展需要的伦理感知,促进基因编辑技术的良性研究与应用。

随着互联网的高速发展,影响力最大化算法在病毒营销、谣言遏制等众多领域得到广泛应用,它旨在搜索一个指定规模的种子节点集,以实现影响力传播范围最大化.尽管已有许多影响力最大化算法被提出,复杂系统的时序特征却鲜有被纳入考量.为了解决时序网络中的影响力最大化问题,本文提出了一种基于时序网络节点嵌入的影响力最大化算法(Micro-and Macro-based Clustering,MMC).该算法能够通过节点嵌入有效地学习时序网络中的微观和宏观维度上的动力学特征.基于嵌入向量,对时序网络进行簇聚类,以降低影响力最大化算法的复杂度,减小种子节点集间的影响力范围重叠,从而进一步提升算法的效果.为了验证MMC的有效性,本文在真实时序网络中进行了影响力传播实验与相似性比较.结果显示,相较于其他5种对比算法,MMC筛选出的种子节点在保证较好的传播效果的同时,能够跳出既有算法的框架.参数敏感性的分析表明,节点聚类过程有效地提升了算法效果.
