摘要：A clustering algorithm based on Sparse Projection (SP), called Sparse Projection Clus- tering (SPC), is proposed in this letter. The basic idea is applying SP to project the observed data onto a high-dimensional sparse space, which is a nonlinear mapping with an explicit form and the K-means clustering algorithm can be therefore used to explore the inherent data patterns in the new space. The proposed algorithm is applied to cluster a complete artificial dataset and an incomplete real dataset. In comparison with the kernel K-means clustering algorithm, the proposed algorithm is more efficient.

摘要：Unlike traditional fiction, Virginia Woolf＇s ＂The Mark on the Wall＂ doesn＇t have lively characters, detailed setting, or intriguing plot. Discarding the traditional narrative mode of zero focalization, the narrator adopts a new fixed internal focalization, interwoven with the first person external point of view. By weakening the physical time and space, the narrator tells the story according to her psychological time and space, stressing the moment of importance, through which the writer highlights her subjective reality.

摘要：Alice Ridout and Susan Watkins offers a best perspective in their book Doris Lessing： Border Crossings, to contemplate Lessing’s writing. In her 57-year publishing career, Lessing always crosses the borders： as a feminist or anti-feminist, as a science fiction writer or a realist who lost her way, as a Marxist or a reactionary, as a British writer or a postcolonial one. Lessing’s border-crossing not only lies in her different genres of writing or in different novels, but even in a single comparatively traditional novel. The Summer Before the Dark is a representative work of Lessing’s women portrayal transition from focusing on their outside world exploration to on their inner world seeking. This essay tries to look at the content and form of the novel, and to illustrate that Lessing’s border-crossing is also fulfilled in one single novel. She successfully crosses the border of convention and innovation： conventional in content, while innovative in form.

摘要：发现和优化纳米复合材料可以通过融合从头算方法和机器学习(ML)来实现,目前的瓶颈在于缺乏原子尺度上描述单体间相互作用的ML模型.我们开发了名为双区域网络(DRN)的深度学习算法,通过训练学习原子之间的多尺度交互作用,预测了由337种不同分子组成的分子对在随机构型中的电子耦合强度,平均绝对误差低至2.8 meV.基于两种截止半径的层次化材料表象被证明对DRN模型的高迁移性和鲁棒性至关重要,这种材料表征方式不仅捕获了共轭片段的局部特征,而且在模型训练之前编码了重要的分子片段间相互作用.本研究建立的ML模型为描述单体间相互作用提供了普适的建模框架,为复杂纳米复合材料的逆向设计打下了基础.

摘要：Manipulation always means a kind of extraordinary alteration for some purposes. All translation implies a degree of manipulation of the source text for a certain purpose. Liang Shih-chiu＇s literary translation serves for his literary creation which aims to promote colloquialism and to construct New Literature in the May Fourth Movement. Literary translation is the foundation of literary creation, or rather, its important strategy. The paper, from the perspective of Manipulation Theory, analyzes the purpose and strategy of Liang Shih-chiu＇s literary translation and explores the influence of his literary translation upon his literary creation in terms of ideology, poetics and patronage.

摘要：Wuchuan Piaose Art is a traditional folk cultural activity of the Han nationality in Wuchuan City,Guangdong *** is a comprehensive plastic art integrating drama,music,art,magic,acrobatics,and *** and recording the intangible cultural heritage of Wuchuan in an Internet+and computer-aided way is of great significance to the practice and historical research of *** provides a folklore material for the artistic creation of figure paintings,which is of pioneering significance.

摘要：In this paper, we conduct research on the landscape painting in Ming and Qing dynasties of the art of Wu School. The Wu School of art is full of creativity, they worship nature, between large vigorous refined landscape painting in the real world with fast red green courtyard, this spirit of the innovation to future generations of artists with great inspiration, Wu school opened up the artistic development for future generations, direct and profound infi uence after the landscape painting and flower and bird painting. Today, we are in the pursuit of the traditional Chinese painting of change, innovation, modernization, “Wu door school” this group of literati painter to do a historical retrospect that is a positive significance. Based on this historical time, we analyze the corresponding theories to provide the systematic research that will be meaningful.

摘要：English pronunciation at segmental level plays a very significant role in learning and teaching of English *** paper aims to investigate into the most salient pronunciation problems at segmental level by college students from China's Mainland(Mandarin L1 speakers)through a close study,and it is found that the problems identified in the segmental aspects of English pronunciation are corresponded with the phonological features of the pronunciation of Chinese ***,in order to help college students improve their pronunciation and achieve the pronunciation of Standard English,this study provide some pedagogical implications and suggestions about teaching strategies aimed at the most salient problems discovered in the research findings.

摘要：Although intelligent hydrogels have shown bright potential application in biomedical fields,they were prepared by conventional methods and still face many serious challenges,such as uncontrollable stimulus-response and low response ***,RAFT polymerization provides a versatile strategy for the fabrication of intelligent hydrogels with improved stimulus-response properties,owing to the ability to efficiently construct hydrogel precursors with well-defined structure,such as block copolymer,graft copolymer,star *** this review,we summarized the recent progress on intelligent hydrogels based on RAFT polymerization with emphasis on their fabrication strategies and applications for controlled drug delivery.
