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。

Activity development of key groups of enzymes involved in municipal refuse decomposition was measured in laboratory landfill bioreactors with and without leachate recycling and inoculation for about 210 days. The results showed that the enzymes (amylase, protease, cellulase, lipase and pectinase) were present in fresh refuse but at low values and positively affected by leachate recycling and refuse inoculation. The total average of cellulase activity in digesters D3 operated with leachate recycling but no inoculation, D4 and D5 operated with leachate recycling and inoculation was much higher than that in digesters D1 and D2 without leachate recycling and inoculation by 88%—127%, 117%—162% and 64%—98%. The total average of protease activity was higher in digester D4 than that in digesters D1, D2, D3 and D5 by 63%, 39%, 24% and 24%, respectively, and the positive effect of leachate recycling and inoculation on protease activity of landfilled refuse mainly was at the first two months. The total average of amylase activity was higher in digesters D3, D4 and D5 than that in digesters D1 and D2 by 83%—132%, 96%—148% and 81%—129%. During the early phase of incubation, the stimulatory effect of inoculation on lipase activity was measured, but refuse moisture was the main factor affecting lipase activity of landfilled refuse. The inoculation, initial and continuous inoculation of microorganisms existing in leachate, was the mainly stimulatory factor affecting pectinase activity of landfilled refuse.

糖基化修饰是一种重要的蛋白翻译后修饰,细胞膜上的蛋白一般多为糖蛋白,细胞内也不断发生着不同类型的糖基化修饰反应。糖蛋白参与到宿主的众多生命过程中,包括细胞生长、细胞间相互识别、免疫应答、病毒入侵及炎症反应的发生等。随着蛋白质组学和糖组学技术的不断完善,蛋白的糖基化修饰研究得到越来越广泛的重视。随着生物技术的不断发展,研究方法不断完善,我们对糖基化修饰所带来的蛋白功能与构象的改变也有了越来越清楚的了解。关于糖型分析及糖蛋白上不同糖型比例的问题也随着糖蛋白的检测、分离纯化、糖基化氨基酸位点测定、糖链结构的分析等实验技术的不断完善得到解决。糖基化对多种疫苗候选抗原的免疫原性影响已有许多相关研究,例如乙型肝炎病毒、人类免疫缺陷病毒(human immunodeficiency virus,HIV)、流感病毒以及新型冠状病毒等疫苗抗原/候选抗原都有不同程度糖基化修饰,糖基化修饰对这些疫苗抗原的影响同样非常重要。本文就糖基化研究方法及糖基化对多种疫苗免疫原性的影响进行综述。

Let M be a 2n-dimensional smooth manifold associated with the structure of symplectic pair which is a pair of closed 2-forms of constant ranks with complementary kernel foliations. Let Q ■M be a codimension 2 compact submanifold. We show some sufficient and necessary conditions on the existence of the structure of contact pair (α,β) on Q, which is a pair of 1-forms of constant classes whose characteristic foliations are transverse and complementary such that α and β restrict to contact forms on the leaves of the characteristic foliations of β and α, respectively. This is a generalization of the neighborhood theorem for contact-type hypersurfaces in symplectic topology.

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。

Recently, Sun et al. (2005) highlighted the essential property of perfect forward secrecy (PFS) for e-mail protocols when a higher security level is desirable. Furthermore, Sun et al. (2005)’s protocols take only a single e-mail server into account. Actually, it is much more common that the sender and the recipient register at different e-mail servers. Compared to existing protocols, the protocol proposed in this paper takes into account the scenario that the sender and the recipient register at different servers. The proposed protocol is skillfully designed to achieve PFS and end-to-end security as well as to satisfy the requirements of confidentiality, origin, integrity and easy key management. The comparison in terms of functionality and computational efficiency demonstrates the superiority of the present scheme.

Fiber optic sensor has been widely used as a structural health monitoring device by either embedding into or surface bonding onto the structures. The strain of optic fiber induced by the host material is strongly dependent on the bonding characteristics which include the protective coating, adhesive layer and the length of bonding. The strains between the fiber optics and host structure are not exact the same. The existence of the protective coating and adhesive layer would affect the strain measured by the surface bonding optic sensor. The analytical expression of the strain in the optic fiber induced by the host material was presented. The results were validated by the finite element method. The theoretical predictions reveal that the strain in the optical fiber is lower than the strain of host material. Parametric study shows that a long bonding length and high modulus of protective coating would increase the percentage of strain transferring into the optical fiber. Experiments were conducted by using Mach-Zehnder interferometer to measure the strain of the surface bonding optic fiber induced by the host structure. Good agreements were observed in comparison with the experimental results and theoretical predictions.

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.
