超大城市的规模扩张意味着广域范围的城市乡村的联动发展。在这一空间重构过程中,城乡关系的分野被忽视了,超大城市借助于交通、项目甚至新城建设“侵入”乡村,从而模糊了城乡边界。随着新城直接面向乡村治理,超大城市实现了“乡政村治”向“村政城治”的逻辑转换。在这一过程中,超大城市通过织密权力网络、集中居住等政策强化城市在地性公共服务对于乡村治理的引领,但是这一思路又强化了村庄对于超大城市的依附。超大城市的乡村振兴需要承认城乡关系的历时性特征,系统反思新城建设、乡村发展中的空间、产业与人口关系联动,通过政策均衡实现超大城市生态、生产、生活功能的内在契合。

目前古籍钤印分类研究中存在对钤印概念的内涵和外延理解不准确,对钤印类型的多样化和复杂性认识不充分,对钤印分类依据、方法的规范性和科学性把握不恰当等不足。解决上述不足,可以“古籍钤印”作为顶层概念,在借鉴既有分类成果并占有更多材料的基础上,以功能为分类依据,将古籍钤印分为出版印、流传印两大类目,分别包含若干下位分类,从语义、语法、语用等角度就类目的概念、印文内容及印文组织形式进行综合剖析,重新构建种类涵盖广泛、类目设计合理、层级关系分明的古籍钤印分类体系,推动新时期古籍钤印整理研究工作的深入。

大数据分类算法在处理海量多源异构数据时存在精度差、效率低等问题,为此提出了一种在云计算环境下基于X-means的优化聚类算法。先构建云计算框架体系,包括用户层、应用层、平台层、资源层和后台管理层;基于RF优化算法对多源异构数据集做融合预处理,降低泛化误差的同时也能实现对数据集的粗分类;基于X-means优化聚类算法计算出数据聚类数量上下限值,不但提升数据训练的效率和降低算法的复杂度,还使距离平均误差值得到较好的控制。在实验室搭建了1个master节点和5个slave节点的云框架,实验结果显示,提出的分类算法在处理海量多源异构数据集时具有更强的分类精度和抗漂移性,同时在分类效率方面也具有一定优势。

Allophane as a Nanotechnological Additive in Masonry Materials to Increase Resistance and Waterproofing

引用

Advances in Materials Physics and Chemistry 2024年第8期14卷 196-212页

作者： Edward H. Jiménez Joao Rivera Juan H. Villalba Paola E. Vera marlon cuenca Belén Granja Javier Fuentes Sandra Gavilanes Daniel Hidalgo Fernando Garcia Jose Bermudez Washington Ruiz Alexis Martial Debut Facultad de Ingeniera Qumica Universidad Central del Ecuador Quito Ecuador Facultad de Arquitectura y Urbanismo Universidad Central del Ecuador Quito Ecuador Nanomaterials Characterization Laboratory Universidad de las Fuerzas Armadas ESPE Sangolqu Ecuador

The constant need for high-strength materials in the construction industry promotes the research of additives that improve the properties of masonry materials. The use of allophane as an additive in concrete and mortar mixtures was implemented to improve their strength and waterproofing, respectively, using compression and water absorption tests according to their corresponding standards (ASTM C1231, ASTM D2938, and ASTM C1585). The samples were evaluated at different concentrations and curing ages. In addition, different sand/cement ratios were considered for the mortar. The results revealed that there was a 9.4% increase in compressive strength in concrete and a 23.7% reduction in water absorption in mortar for the 5:1 ratio. These changes would be the result of the interaction of the nanoporous additive in the atomic crystal structure of the material demonstrating the nanotechnological nature of allophane.

Implementing Symmetries of a Free Bose field via White Noise Operators

引用

Acta Mathematica Sinica,English Series 2003年第1期19卷 147-158页

作者： ShunLongLU0 InstituteofAppliedMathematics AcademyofMathematicsandSystemSciencesChineseAcademyofSciencesBeijing1

Linear symmetries of a free Bose field are exploited in the framework of Hida's white noise functionals triple. General symplectic automorphisms on the single particle space are implemented by generalized operators. The intertwining operators are constructed in a physically intuitive way, characterized analytically in terms of symbols, and factorized into three fundamental parts according to Wick ordering procedure. In particular, the classical Shale's theorem is rederived.
