Inductive Graph Unlearning
No full textAs a way to implement the "right to be forgotten" in machine learning, machine unlearning aims to completely remove the contributions and information of the samples to be deleted from a trained model without affecting the contributions of other samples. Recently, many frameworks for machine unlearning have been proposed, and most of them focus on image and text data. To extend machine unlearning to graph data, GraphEraser has been proposed. However, a critical issue is that GraphEraser is specifically designed for the transductive graph setting, where the graph is static and attributes and edges of test nodes are visible during training. It is unsuitable for the inductive setting, where the graph could be dynamic and the test graph information is invisible in advance. Such inductive capability is essential for production machine learning systems with evolving graphs like social media and transaction networks. To fill this gap, we propose the GUided InDuctivE Graph Unlearning framework (GUIDE). GUIDE consists of three components: guided graph partitioning with fairness and balance, efficient subgraph repair, and similarity-based aggregation. Empirically, we evaluate our method on several inductive benchmarks and evolving transaction graphs. Generally speaking, GUIDE can be efficiently implemented on the inductive graph learning tasks for its low graph partition cost, no matter on computation or structure information.

Abstract
The purpose of the present study was to investigate the effect of long-term Wai Tan Kung exercise on heart rate (HR), energy expenditure, oxygen uptake (VO2), ventilation (VE), heart rate variability and blood pressure. Two different groups of older adults were recruited. One group subjects (n =16; 65.0 ± 4.2 yrs, 163.3 ± 7.3 cm, 63.3 ± 7.3 kg) had been participated at least 10 years of regular Wai Tan Kung exercise (long-term group, LTG), and the other (n = 16; 59.0 ± 3.7 yrs, 162.0 ± 3.9 cm, 65.7 ± 3.6 kg) had been participated as same exercise as LTG but less than one year (short-term group, STG). The results of this study showed that there were significant differences (p < .05) in rest systolic pressure, and HR, energy expenditure, VO2, VE, high frequency power (HFP) and low frequency power (LFP) during exercise between LTG and STG (p < .05). LTG subjects had a significant lower in rest heart rate and blood pressure (p < .05) than STG subjects, and the former also reached higher (p < .05) exercise intensities during exercise testing than the latter. Moreover, there were significant higher heart rate, VO2 and VE during exercise testing for LTG than STG, suggesting that LTG subjects had higher metabolic rate. Additionally, LTG had a higher HFP than STG, suggesting that there was a significant increase in parasympathetic division of autonomic nervous activity during exercise testing for LTG than STG, indicating LTG subjects may prevent from coronary artery disease and improve functions of the heart. It is concluded that older adults participate in regular long-term of Wai Tan Kung exercise have a positive effect on their cardiovascular fitness. Therefore, such kind of exercise may especially fit for older adults.
Key words: oxygen uptake (VO2), ventilation (VE), heart rate, heart rate variability, Wai Tan Kung exercise.

No full textA Study on Luo Zhi Cheng\ue2s Historical narrative poems
No full textLuo Zhi Cheng is an important poet in the field of Taiwanese modern poetry, who is known for distinctive linguistic style and intense creative consciousness that are respected. Based on his powerful imagination and flourishing creativity as two primary advantages, through the mediation of poetry, prose, remarks, and commentaries, he maximally amplifies the implication of literature, and thereby composes himself and enriches the character. Distinguished from the majority of researchers focusing on Luo\ue2s lyric works, this study particularly found a writing context of \ue2avoidance of lyric sensibility\ue2 in Luo\ue2s poems, that is, his series of works historical themes in the form of long poems utilizing narrative skills to exhibit the remarkable consistency between the internality and the externality of the author.
\ue3\ue3This study conducted a comparative investigation of Luo\ue2s poetry work (The Book of Zhuzi) and prose works (Austral Court\ue2s Notandum and The Initiation of Civilization) to build a relatively more multi-faceted \ue2author\ue2s image of Luo Zhi Cheng\ue2 according to the writing of works of historical themes. Using the methodology of narratology, I departed from the internality of the text (the collection of poems) to identify how Luo forms the ideal spectrum of character by shaping historical persons; and meanwhile, I equally departed from the collections of prose to grasp the external information of the texts, and thereby clarified that Luo may treat \ue2writing, individual, and society\ue2 as a process of self-fulfillment. It is the two corresponding identities \ue2poet\ue2 and \ue2the intellectual\ue2 that are the mechanism of his constructing self-justification. Such investigation of the internality and the externality of text confirmed the complex relationships of the sustained \ue2opposition,\ue2 \ue2coexistence,\ue2 and \ue2conflict\ue2 between Luo and his works of historical themes
Taiwanese Females\ue2 Europe Writing since the 1990s: Taking Han Liang-Lu, Cheng Hua-Chuan and Hu Ching-Fang for example.
No full textDue to the progress of these decades, women\ue2s rights have been more and more emphasized, and females are not restricted in their families anymore. Independent travelling became to flourish in late 1990s, thus female travel writing shows various styles. Females may fulfill their lives through the process of continuous travelling and conversation.
European civilization developed relatively early, and had long history of art and culture, so Europe is considered to be the dreaming destination of many travelers. The study aims to discuss the female travel writers including Han Liang-lu, Cheng Hua-Chuan and Hu Ching-Fang and etc\ue2\ua6, to analyzes their writing of travelling in Europe to understand the females themselves, find out how it would be like when eastern and western cultures encounter, as well as the image of Europe in the female writers\ue2 articles. The study will analyzes the texts of prose to find out the meaning of travelling to the new-generation female writers through their interation with others, observation and experience in travelling writings.
Han Liang-lu\ue2s downshifting style aims to see the human comedy and diversity of Europe. Cheng Hua-Chuan\ue2s positive description and female writing style are full of passion for knowledge. Finally, Hu Ching-Fang sees the world in the perspective of outsider to remind us to put away prejudice and look into the truth of what is happening right now. These all allow us to have more understanding about traveling
Molecular Weight Dependence of Chain Conformation and Counterion Dissociation of Poly(xylylene tetrahydrothiophenium chloride) in the Salt-Free Semidilute Aqueous Solutions
No full textMeasurements of fluence profiles in femtosecond laser filaments in air
No full textWe introduce a technique to measure fluence distributions in femtosecond laser beams with peak intensity of up to several hundred terawatts per square centimeter. Our ap- proach is based on the dependence of single-shot laser abla- tion threshold for gold on the angle of incidence of the laser beam on the gold sample. We apply this technique to the profiling of fluence distributions in femtosecond laser fila- ments at a wavelength of 800 nm in air. The peak intensity is found to be clamped at a level that depends on the ex- ternal beam focusing. The limiting value of the peak inten- sity attainable in long-range 800 nm air filaments, under very loose focusing conditions (f -number above ∼500), is about 55 TW∕cm2
