They are straightened out on the Jacobi variety of the associated hyperelliptic curve. Explicit algebraic-geometric solution is obtained on the basis of a deeper understanding of the KdV hierarchy.展开更多

It can interpret the comprehension and production of texts. This paper first makes a thematic analysis of the English original text and the Chinese target text, and then makes a comparative study of them in terms of the textual properties. It is found that in reproduction of target text, theme equivalence can not only help to realize the coherence of the target text with the same effect on receptors but also can save translation efforts. It is unnecessary to change the theme-rheme arrangements of the original unless it is required due to the social and cultural differences between English and Chinese.展开更多

It uses the Kolb model and 4MAT learning system to introduce a learning cycle based on collaborative problem solving exercises. The teaching approach based on learning cycle is described giving examples of different teaching elements applied in particular quadrants of the learning cycle. The attitude of students and their different approaches to, learning are presented and discussed in detail. The results presented cover different aspects of the course delivery and students＇ perception. The results include students＇ statistics with respect to their registration and previous history related to the course, their motivatiion, assessment and satisfaction with the approach applied. This initial introduction of cooperative activities into the remedial Dynamics class can be assessed as a positive step in increasing student understanding and performance in the course. The students＇ positive reception of the non-traditional teaching method and their overall improved performance seem to confirm the advantages of collaborative leaming. In terms of the final grades, the results of the experiment were not as good as expected. However, the application of 4MAT learning system which exposed students to a variety of diverse learning styles improved the quality of education. The positive aspect of the experiment was the attitude of students and their acceptance of the new mode of course delivery. In conclusion collaborative learning could be extended beyond remedial groups to normal student classes.展开更多

The groups of approved applications and those that had not been approved were compared for 12 variables： publication time lag; numbers of inventors, classifications, pages, figures, tables, claims, priority claims, countries for priority claims, cited patents, and cited non-patent documents; and median of citation age. Furthermore, the authors carried out the experiments in which patent applications were automatically classified into two groups by the machine learning method, random forests. As a result, statistically significant differences between the two groups were observed for the following variables （p 〈 .001）： the numbers of inventors, pages, figures, claims, priority claims, and countries for priority claims were significantly larger in the group of approved applications, while the time lag until publication was smaller. In particular, the publication time lag and the numbers of inventors, pages, and figures were variables representing the features that largely contribute to discriminating approved applications in the classification using random forests, which implies that these have relatively strong relationships with patentability.展开更多

It focuses on the visual process, artistic feelings, and beauty of form as its creative core. The Chinese Cursive Calligraphy （草书）, on the other hand, aims to create a vibrant beauty resulting from sweeping wrap-around and continuous changes. It also pays attention to the personality stretch, the lyrical and expressive, and the abstract beauty within images. In both arts, there is a rhythmic beauty running through the works, allowing the charm of lines to fully express the artist＇s creative thoughts and feelings, making them stand out impressively.展开更多

Four classical chirographies of ＂Kaisho＂, ＂Gyosho＂, ＂Sousho＂ and ＂Hiragana＂, and 47 characters for each chirography, were selected and analyzed by this system. The ＂Sumi＂ distribution of character was clarified from 12 directions and summarized into four parts of horizontal part, diagonal left part, vertical part and diagonal fight part. The character＇s contour line was converted to a signal data in order to calculate roundness index. The degree of character＇s radian was presented by roundness index. The smooth index was calculated at the same time. Additionally, width index, ＂Sumi＂ ratio, stability index also were calculated to contrast the features of each style. The main character points of four styles of ＂Kaisho＇, ＂Gyosho＂, ＂Sousho＂, ＂Hiragana＂ were extracted to compare each other, and provide a reference for learners. The learners could obtain the quantitative data to understand their work＇s characteristics. It can also be compared with other person＇s work by this system in order to improve learners＇ writing skill.展开更多

文摘Special solution of the （2＋1）-dimensional Sawada Kotera equation is decomposed into three （0＋1）- dimensional Bargmann flows. They are straightened out on the Jacobi variety of the associated hyperelliptic curve. Explicit algebraic-geometric solution is obtained on the basis of a deeper understanding of the KdV hierarchy.
