Thiol-functionalized MCM-41 type mesoporous silica particles（MSPs） were prepared and loaded with silver chloride to act as antibacterial agents. The antibacterial activity of the silver chloride loaded MSPs（AgCI-MSPs） was evaluated by the minimum bactericidal concentration（MBC） against Candida albieans（ATCC 10231）. The AgC1-MSPs with the highest antibacterial activity were then dispersed in hybrid coatings with different mass ratios to fabricate antibacterial coatings. The antibacterial activity of the coatings was tested against Candida albicans{ATCC 10231） and Streptococcus mutans（ATCC 25175）. The resulting antibacterial coatings exhibited high antibacterial activity, good adhesion to the substrate and high hardness.

The goal of this paper is to give a survey of the previous works on the globally optimal distributed Kalman filtering fusion with classical and nonclassical dynamic systems. Then, we summarize some of our recent results on nonclassical and unideal dynamic systems, including dynamic systems with feedback and cross-correlated sensor measurement noises, dynamic systems with random parameter matrices, and dynamic systems with out-of-sequence or asynchronous measurements. The global optimality in this paper means that the distributed Kalman filtering fusion is exactly equal to the corresponding centralized optimal Kalman filtering fusion. Therefore, not only all of the proposed fusion algorithms here are distributed, but performance as good as that of the corresponding optimal centralized fusion algorithms is achieved. There also exist many papers for other fusion optimality (e.g., the optimal convex linear estimation/compression fusion) discussion, which are not involved in this paper.

Forest volume, the major component of forest biomass, is an important issue in forest resource *** is estimated from tree volume tables or equations. Based on tree volume data of 1840 sample trees from Chinese fir （Cunninghamia lanceolata） plantations in Guizhou Province in southwestern China, parallel one- and two-variable tree volume tables and tree height curves for central and other areas were constructed using an error-in-variable modeling method. The results show that, although the one-variable tree volume equations and height curves between the central and other areas were significantly different, the two-variable volume equations were sufficiently close, so that a generalized two-variable tree volume equation could be established for the entire province.

People-centric activity recognition is one of the most critical technologies in a wide range of real-world applications,including intelligent transportation systems, healthcare services, and brain-computer interfaces. Large-scale data collection and annotation make the application of machine learning algorithms prohibitively expensive when adapting to new tasks. One way of circumventing this limitation is to train the model in a semi-supervised learning manner that utilizes a percentage of unlabeled data to reduce the labeling burden in prediction tasks. Despite their appeal, these models often assume that labeled and unlabeled data come from similar distributions, which leads to the domain shift problem caused by the presence of distribution gaps. To address these limitations, we propose herein a novel method for people-centric activity recognition,called domain generalization with semi-supervised learning(DGSSL), that effectively enhances the representation learning and domain alignment capabilities of a model. We first design a new autoregressive discriminator for adversarial training between unlabeled and labeled source domains, extracting domain-specific features to reduce the distribution gaps. Second, we introduce two reconstruction tasks to capture the task-specific features to avoid losing information related to representation learning while maintaining task-specific consistency. Finally, benefiting from the collaborative optimization of these two tasks, the model can accurately predict both the domain and category labels of the source domains for the classification task. We conduct extensive experiments on three real-world sensing datasets. The experimental results show that DGSSL surpasses the three state-of-the-art methods with better performance and generalization.

Inspired by Phil Benson＇s study on the relations between ethnocentrism and the China-related entries in the OED2, this paper attempts to further examine how the image of China, a so--called ＂peripheral object of Western knowledge,＂ has been （ntis-） constructed in the dictionary, particularly its latest 2009 CD-ROM version, into which many laudable updates, including corrections and supplements, have been meticulously incorporated. It argues that （ 1 ） although British imperialism was a closed chapter, its vestiges can still be spotted in the dictionary text, not only in the quotations, which preserve historical information rather than reflect the editors＇ opinions, but also in the definitions and notes, which betray primarily the thoughts of these editors, （ 2 ） to an average user, the OED, with its legendary philological authority, is very likely to project ＂ historical objectivity＂ into some problematic contents and thus misleads an innocent and uninformed mind, and （3） if ethnocentrism is an unavoidable component in the OED1 and OED2, then the editorial team of the OED3 in the making would do well to introduce into their work an element of＂＂ entholocalism,＂ by which is meant the ideological neutrality as well as the technical accuracy of encyclopedic information about such important peripheral objects as China, the most populous country and a fast growing economy, in the world in which the English language against the backdrop of globalization has firmly established itself as the international lingua fianca without rival. So long as it is intended to remain a historical dictionary true to its name, the OED ought to push forward, in the form of new editions, with the times.

Theoretically, the Chinese-English dictionary （CED） is vitally important to the translation of Chinese classics into English（TOCCIE）. In reality, however, many CEDs in general use fail more or less to function as an indispensable aid in TOCCIE actions by offering either inadequate information or, more alarmingly, partial or even total misinformation in Chinese-civilization-specific entries that defy easy rendering. This paper attempts to illustrate this deplorable fact with a case study of the Buddhism-related entries （BILE） in three CEDs representative of state-of-the-art Chinese bilingual lexicography. The conclusion is that it is high time to substantially improve the CED as an important TOCCIE aid, so that a large-scale, systematic execution of TOCCIE, which seems befitting the global image of present-day China as a rising power not only politico-economically but also culturally, will be performed with greater facility.
