Chuan-Hui Shan,Xi-Rong Guo,Jun Ou 제어·로봇·시스템학회 2019 International Journal of Control, Automation, and Vol.17 No.10

Recently, Deep learning has made a great deal of success in processing images, audios, and natural languages and so on. The activation function is one of the key factors in Deep learning. In this paper, according to characteristics of biological neurons, an improved Leaky Single-Peaked Triangle Linear Unit (LSPTLU) activation function is presented for the right-hand response unbounded of Rectified Linear Unit (ReLU) and Leaky ReLU(LReLU). LSPTLU is more in line with the biological neuron essence and achieves the excellent performance of equivalent or beyond ReLU and LReLU on different datsets, e.g., MNIST, Fashion-MNIST, SVHN, IMAGENET, CALTECH101 and CIFAR10 datasets.

Revenge Tragedy Meeting City Comedy: Alan Ayckbourn’s The Revengers’ Comedies

Hui-chuan Wang 한국중세근세영문학회 2009 중세르네상스 영문학 Vol.17 No.1

Since the 1980s there has been a marked interest, in the British theatre, in the non-Shakespearean early modern plays, particularly two subgenres of Jacobean drama—revenge tragedy and city comedy. Jacobean drama finds renewed favour because it seems strangely modern and familiar, staging conflicts and tensions that preoccupy many minds in the late twentieth century. It is in this context of recent Renaissance revivals that we can read British playwright Alan Ayckbourn’s The Revengers’ Comedies (1989). The play charts the double revenge plans of two complete strangers who undertake each other’s revenge, a scheme reminiscent of the plot of Patricia Highsmith’s thriller Strangers on a Train. The title of the play, however, clearly alludes to a Jacobean precedent, Middleton/Tourneur’s The Revenger’s Tragedy. Initially famous for his comedies about the dullness of suburban English middle-class lives, Ayckbourn turned his attention in the 1980s to broader social issues, condemning the materialism of Thatcherite Britain in several plays. The Revengers’ Comedies satirizes the unscrupulous and irresponsible behaviour of the multinational corporation and points to the harmful effects it has on the society. The playwright adapts conventions of both revenge tragedy and city comedy to a modern story.

Antioxidant properties of porcine liver proteins hydrolyzed using Monascus purpureus

Hui-Chuan Yu,Jue-Liang Hsu,Chi-I. Chang,Fa-Jui Tan 한국식품과학회 2017 Food Science and Biotechnology Vol.26 No.5

In this study, the antioxidant activities of porcine liver proteins, hydrolyzed using Alcalase®, papain, pepsin, or a microbial suspension of Monascus purpureus (APLH, PaPLH, PePLH, and MPLH, respectively), were investigated. The results indicated that the yield and degree of hydrolysis (DH) of hydrolysates increased with hydrolysis time. The highest yield and peptide content were obtained from APLH, whereas the DH of PaPLH was higher than that of the others. MPLH exhibited the highest 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and reducing power, whereas APLH and PaPLH exhibited the higher ferrous ion-chelating ability than that of the MPLH. The molecular weights of all the hydrolysates were <10 kDa. The PaPLH exhibited the highest contents of total amino acids and hydrophobic amino acids. Fifteen antioxidant fractions obtained from MPLH contained one or more of the following amino acids in their sequences: Tyr, Trp, Ala, Pro, Met, Lys, Asp, Cys, Val, Leu, and His.

The Acquisition of Spanish Clitic Pronouns as a Third Language: A Corpus-based Study

Lu, Hui-Chuan,Cheng, An Chung,Chu, Yu-Hsin Institute for Corpus Research 2020 Asia pacific journal of corpus research Vol.1 No.2

This corpus-based study investigated third language acquisition by Taiwanese college students in learning Spanish clitic pronouns at beginning and intermediate levels. It examined the acquisition sequences of Spanish clitic pronouns of the Chinese-speaking learners whose second language was English and third language was Spanish. The results indicated that indirect object pronouns (OP) preceded direct OP (case), first person preceded third person OP (person), masculine preceded feminine OP (gender), and animate preceded inanimate OP (animacy). The findings presented similar patterns as those of previous studies on English-speaking learners of Spanish. In further comparisons of the target forms in Chinese, English, and Spanish, the results suggested that L1 Chinese had strong influence on L3 Spanish, which accounts for the challenges that Taiwanese learners of Spanish face as they learn the Spanish clitic pronouns in the beginning stage.

A Corpus-Based Study on Language Features and Literary Themes in the Yellow Wall-Paper and Herland by Charlotte Perkins Gilman

Lu, Hui-Chuan,Liu, Kai-Ling,Yeh, Chien-Ting,Chen, Ya-Jie Institute for Corpus Research 2022 Asia pacific journal of corpus research Vol.3 No.1

This study aims to apply corpus-based approach to analyze The Yellow Wall-Paper and Herland written by Charlotte Perkins Gilman, a women's rights activist in the late nineteenth-century America. Although both works have attracted feminists' attention to the woman question that concerned Gilman, discussion on her language features and their relation to the literary themes of these two works is still in need. In this corpus-based analysis, we argue that the main themes of different literary works can be revealed through linguistic patterns identified by number and gender features of nouns and pronouns in the contrast of two works and a balanced corpus. The linguistic features (number and gender) have been related with two themes, the 'group and individual' and the 'feminine and masculine', and are further interpreted in terms of mothering and feminine consciousness. By adopting linguistic approach, our study provides quantitative and qualitative evidence to verify the established themes and arguments of these literary texts.

Optimization of ultrasonic-assisted enzymatic hydrolysis conditions for the production of antioxidant hydrolysates from porcine liver by using response surface methodology

Yu, Hui-Chuan,Tan, Fa-Jui Asian Australasian Association of Animal Productio 2017 Animal Bioscience Vol.30 No.11

Objective: The objective of this study was to optimize ultrasonic-assisted enzymatic hydrolysis conditions, including enzyme-to-substrate (E/S) ratio, pH, and temperature, for producing porcine liver hydrolysates (PLHs) with the highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity by using response surface methodology (RSM). Methods: The study used RSM to determine the combination of hydrolysis parameters that maximized the antioxidant activity of our PLHs. Temperature ($40^{\circ}C$, $54^{\circ}C$, and $68^{\circ}C$), pH (8.5, 9.5, and 10.5), and E/S ratio (0.1%, 2.1%, and 4.1%) were selected as the independent variables and analyzed according to the preliminary experiment results, whereas DPPH free radical scavenging activity was selected as the dependent variable. Results: Analysis of variance showed that E/S ratio, pH, and temperature significantly affected the hydrolysis process (p<0.01). The optimal conditions for producing PLHs with the highest scavenging activity were as follows: E/S ratio, 1.4% (v/w); temperature, $55.5^{\circ}C$; and initial pH, 10.15. Under these conditions, the degree of hydrolysis, DPPH free radical scavenging activity, ferrous ion chelating ability, and reducing power of PLHs were 24.12%, 79%, 98.18%, and 0.601 absorbance unit, respectively. The molecular weight of most PLHs produced under these optimal conditions was less than 5,400 Da and contained 45.7% hydrophobic amino acids. Conclusion: Ultrasonic-assisted enzymatic hydrolysis can be applied to obtain favorable antioxidant hydrolysates from porcine liver with potential applications in food products for preventing lipid oxidation.

Li, Jun-Chuan,Zhu, Hong-Yu,Chen, Ting-Xuan,Zou, Lan-Ying,Wang, Xiao-Yan,Zhao, Hui-Chuan,Xu, Jun Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10

Objective: This study aimed to examine the relationship between expression of mammal target of rapamycin (mTOR) and phosphorylation of mTOR (p-mTOR) protein in the PI3K/Akt/mTOR signaling pathways in gastrointestinal stromal tumors and relatiuonships with clinical factors. Methods: Immunohistochemistry was used to detect the expression of the associated proteins mTOR, p-mTOR, and phosphorylation of the tumor suppressor genes PTEN, P27, VEGF, and EGFR in 40 cases of gastrointestinal stromal tumors, with division into a very low and low risk group as well as a moderate and high risk group. Results: The positive rate of mTOR and p-mTOR was significantly increased in the moderate and high risk group compared with the very low and low risk group. The difference was statistically significant (P<0.05). When grouped according to size, the positive mTOR expression rate exhibited a statistical difference (P<0.05), which was significantly increased in the group of tumors larger than 5 cm. The difference in the positive mTOR and p-mTOR expression rate exhibit no statistical significance among the PTEN, P27, VEGF, and EGFR expression subgroups (P>0.05). Conclusion: The different expressions of mTOR and p-mTOR in the signal transduction pathway of gastrointestinal stromal tumor in the different degree-of-risk groups suggested that the mTOR and p-mTOR of the signal transduction pathway serve an important function in the occurrence and development of gastrointestinal stromal tumors.

A Novel Virtual Space Vector Modulation Strategy for the Neutral-Point Potential Comprehensive Balance of Neutral-Point-Clamped Converters

Chuan-Jin Zhang,Yi Tang,Dong Han,Hui Zhang,Xiao Zhang,Ke Wang 전력전자학회 2016 JOURNAL OF POWER ELECTRONICS Vol.16 No.3

A novel Virtual Space Vector (VSV) modulation strategy for complete control of potential neutral point (NP) issues is proposed in this paper. The neutral point potential balancing problems of multi-level converters, which include elimination of low frequency oscillations and self-balancing for NP dc unbalance, are investigated first. Then a set of improved virtual space vectors with dynamic adjustment factors are introduced and a multi-objective optimization algorithm which aims to optimize these adjustment factors is presented in this paper. The improved virtual space vectors and the multi-objective optimization algorithm constitute the novel Virtual Space Vector modulation. The proposed novel Virtual Space Vector modulation can simultaneously recover NP dc unbalance and eliminate low frequency oscillations of the neutral point. Experiment results show that the proposed strategy has excellent performance, and that both of the neutral point potential issues can be solved.

Perceived instructional leadership and teacher self-efficacy of online teaching in Taiwan: Mediating effects of teacher professional community

Chuan-Chung Hsieh,Imam Gunawan,Hui-Chieh Li 한국교육개발원 2023 KEDI Journal of Educational Policy Vol.20 No.1

This study aimed to examine the mediating effects of teacher professional community on the relationship between perceived instructional leadership and teacher self-efficacy of online teaching in Taiwan. Data were collected from elementary and middle school teachers via an online survey using a questionnaire designed with well-developed scales. Analysis showed that perceived instructional leadership has no direct effect on teacher self-efficacy and that teacher professional community mediates fully the relationship between perceived instructional leadership and teacher self-efficacy. Among the four teacher professional community components examined, shared norms showed the most significant mediating effect. Results also revealed no significant difference in the relationships between variables across teachers in elementary and middle schools. Implications for school leadership and teacher learning are discussed.
