According to the mechanism of EMG signal, we know that the sacrificial electrical signal is with weak signal, low frequency, alternating, nonlinear and non-stationary characteristics. Nonlinear analysis includes higher order spectral analysis and fractal and chaos analysis.Chaos theory is one of the main parts of nonlinear science, and the electrical signal of the surface has a strong randomness, so we could consider the nonlinear analysis of EMG signals from the perspective of chaos. We mainly studied on the nonlinear analysis algorithm of EMG signal detailedly in this paper. Experiments show that,according to the quantitative analysis of several important parameters of rolling massage with chaos theory, we can measure objectively the action situation of related muscle groups in the operation course, then guide the professional massage students to understand the norms of operation in training of operation and help to lead their manipulation to the best power structure.

Chao Wang,Jian-Hui Wang,Shu-Sheng Gu,Xiao Wang,Yu-Xian Zhang 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.3

The elongation of steel-strips in annealing furnace is an important factor that affects the position ofwelding line and safety of air-knife since there is no extra space to install welding line detector in field conditions. Therefore, predicting the elongation of steel-strips in the annealing process is important to fulfill the requirementsof eliminating security risks and improving economic performance. In this paper, we propose a deep architecturescalled I-ELM/MLCSA autoencoders with the concept of stacked generalization philosophy to solve large and complexdata mining problems. The comparison results of the case studies indicate that D-ELMs-AE/MLCSA is apromising prediction algorithm and can be employed for steel-strips elongation predictions with excellent performance.

Currently, taxol is mainly extracted from the bark of yews; however, this method can not meet its increasing demand on the market because yews grow very slowly and are a rare and endangered species belonging to first-level conservation plants. Recently, increasing efforts have been made to develop alternative means of taxol production; microbe fermentation would be a very promising method to increase the production scale of taxol. To determine the activities of the taxol extracted from endophytic fungus N. sylviforme HDFS4-26 in inhibiting the growth and causing the apoptosis of cancer cells, on comparison with the taxol extracted from the bark of yew, we used cellular morphology, cell counting kit (CCK-8) assay, staining (HO33258/PI and Giemsa), DNA agarose gel electrophoresis and flow cytometry (FCM) analyses to determine the apoptosis status of breast cancer MCF-7 cells, cervical cancer HeLa cells and ovarian cancer HO8910 cells. Our results showed that the fungal taxol inhibited the growth of MCF-7, HeLa and HO8910 cells in a dose-and time-dependent manner. IC50 values of fungal taxol for HeLa, MCF-7 and HO8910 cells were $0.1-1.0{\mu}g/ml$, $0.001-0.01{\mu}g/ml$ and $0.01-0.1{\mu}g/ml$, respectively. The fungal taxol induced these tumor cells to undergo apoptosis with typical apoptotic characteristics, including morphological changes for chromatin condensation, chromatin crescent formation, nucleus fragmentation, apoptotic body formation and G2/M cell cycle arrest. The fungal taxol at the $0.01-1.0{\mu}g/ml$ had significant effects of inducing apoptosis between 24-48 h, which was the same as that of taxol extracted from yews. This study offers important information and a new resource for the production of an important anticancer drug by endofungus fermentation.

Wang, Chao,Xiao, Qian,Li, Yu-Wen,Zhao, Chao,Jia, Na,Li, Rui-Li,Cao, Shan-Shan,Cui, Jia,Wang, Lu,Wu, Yin,Wen, Ai-Dong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7

Adenocarcinoma of lung has high incidence and a poor prognosis, woith chemotherapy as the main therapeutic tool, most commonly with cisplatin. However, chemotherapy resistance develops in the majority of patients during clinic treatment. Mechanisms of resistance are complex and still unclear. Although annexin play important roles in various tumor resistance mechanisms, their actions in cisplatin-resistant lung adenocarcinoma remain unclear. Preliminary studies by our group found that in cisplatin-resistant lung cancer A549 cells and lung adenocarcinoma tissues, both mRNA and protein expression of annexins A1, A2 and A3 is increased. Using a library of annexin A1, A2 and A3 targeting combined molecules already established by ourselves we found that specific targeting decreased cisplatin-resistance. Taken together, the underlined effects of annexins A1, A2 and A3 on drug resistance and suggest molecular mechanisms in cisplatin-resistant A549 cells both in vivo and in vitro. Furthermore, the study points to improved research on occurrence and development of lung adenocarcinoma, with provision of effective targets and programmes for lung adenocarcinoma therapy in the clinic.

Discussion on the Religiousness of Confucianism in the Past Century

( Wang Xiao-chao ) 성균관대학교 유교문화연구소 2017 儒敎文化硏究(中文版) Vol.0 No.27

百年來對於儒家宗敎性問題的討論, 呈現出多種思想匯流交錯的格局。胡適、馮友蘭一直到陳來所代表的理性人文主義, 在相當長的時間內都占據主流。在這個大的背景下, 很多哲學以及宗敎社會學學者, 將宗敎性視爲儒家思想的殘餘。牟宗三、唐君毅等以“內在超越”來解釋儒家“天人合一”的宗敎性, 其主張影響深遠。任繼愈、李申出於批判傳統社會現實的需要, 認爲儒家就是宗敎;而蔣慶、陳明等重提康有爲孔敎論, 意圖將儒家重建爲國敎或公民宗敎。然而, 大多數學者幷不接受“儒家是敎”, 而僅肯定儒家有終極關懷。著眼於社會實踐, 安樂哲認爲儒家是“以禮爲中心”的角色倫理, 在社群對個體的塑造過程中體現出相當的宗敎性;而著眼於個人的修身實踐, 張學智等也論述了傳統士大夫實現終極關懷的功夫論進路。最終, 與“內在超越”一脈相承, 杜維明提出精神性人文主義, 堅決區別於缺乏宗敎關懷的凡俗人文主義。同時, 他也指出, “內在超越”的儒家傳統可以與“外在超越”的西方宗敎傳統幷行不悖, 互相對話。 There have been wide-ranging discussions on the religiousness of Confucianism in the past century. The rational humanism occupied the mainstream for quite long time. In the context of rational humanism, many philosophers and sociologists regard the religiousness of Confucianism as remains. Mou Zongsan proposes the theory of “immanent transcendence” to explain the “unity of heaven and man.” For negative or positive purposes, some scholars consider Confucianism as a religion. Meanwhile, many others offer different interpretations: Confucianism only has ultimate concern in either social or personal practice. Tu Weiming proposes “spiritual humanism” to draw a clear distinction from “secular humanism.” He also points out that “immanent transcendence” and “external transcendence” can develop independently and should engage in meaningful cultural dialogue.

Yan-chao Wang,Jin-miao Lu,Hui-zi Jin,Ai-niu Ma,Jin-yang Zhang,Nian Gong,Qi Xiao,Bin Zhu,Ying-fang Lv,Na Yu,Wei-dong Zhang,Yong-xiang Wang 한국영양학회 2014 Nutrition Research and Practice Vol.8 No.2

BACKGROUND: Groundwater is believed to possess many beneficial effects due to its natural source of various minerals. In this study, we examined the effects of natural Jeju groundwater S1 (SamdasooTM), S2 and S3 pumped up from different locations of Jeju Island, Korea, along with local tap water, on body weight gain, serum lipids and lipoproteins, and liver histopathology in high-fat diet-induced hyperlipidemic rats. MATERIALS/METHODS: Rats were randomly and equally divided into 6 groups. Different water samples were supplied to the hyperlipidemic rats as their daily drinking water and the widely-used anti-hyperlipidemic drug simvastatin was used as a positive control. Body weight, serum lipids and lipoproteins were measured weekly. Liver weight, liver index and liver histopathology were examined after the execution of the rats. RESULTS: After drinking Jeju groundwaters for two months, S2 but not S3 significantly reduced weight growth and serum triglycerides levels and increased high density lipoprotein-C (HDL-C) without affecting total cholesterol or LDL-C. S1 and particularly S2 significantly reduced the severity of liver hypertrophy and steatosis. All Groundwaters had much higher contents of vanadium (S3>S2>S1>>tap water) whereas S1 and S2 but not S3 markedly blocked autoxidation of ferrous ions. CONCLUSION: Jeju Groundwater S1 and particularly S2 exhibit protective effects against hyperlipidemia and fatty liver and hypothesize that the beneficial effect of Jeju Groundwaters may be contributed from blockade of autoxidation of ferrous ions rather than their high contents of vanadium.

Fuzzy Neural Network Active Disturbance Rejection Control for Two-Wheeled Self-Balanced Robot

Chao Wang,Xiao Jianliang,Cheng Zhang 한국정보처리학회 2022 Journal of information processing systems Vol.18 No.4

Considering the problems of poor control effect, weak disturbance rejection ability and adaptive ability of twowheeledself-balanced robot (TWSBR) systems on undulating roads, this paper proposes a fuzzy neural networkactive disturbance rejection controller (FNNADRC), that is based on fuzzy neural network (FNN) for onlinecorrection of active disturbance rejection controller (ADRC)’s nonlinear control rate. Firstly, the dynamicmodel of the TWSBR is established and decoupled, the extended state observer (ESO) is used to compensatedynamically and linearize the upright and displacement subsystems. Then, the nonlinear PD control rate andFNN are designed, and the FNN is used to modify the control parameters of the nonlinear PD control rate inreal time. Finally, the proposed control strategy is simulated and compared with the traditional ADRC andfuzzy active disturbance rejection controller (FADRC). The simulation results show that the control effect ofthe proposed control strategy is slightly better than ADRC and FADRC.

Caveolin-1, Through its Ability to Negatively Regulate TLR4, is a Crucial Determinant of MAPK Activation in LPS-challenged Mammary Epithelial Cells

Wang, Xiao-Xi,Wu, Zheng,Huang, Hui-Fang,Han, Chao,Zou, Wei,Liu, Jing Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.4

Background: To explore the role of caveolin-1(CAV-1) gene silencing on MAPK activation in lipopolysaccharide (LPS)-challenged human mammary epithelial cells. Methods: We established a MCF-10ACE of CAV-1 gene silencing from human mammary epithelial cell line MCF-10A by RNAi technology. DNA Microarray were used to detect the expression of inflammation-associated genes in MCF10ACE. Western blotting was used to examine the activation of MAPK in lipopolysaccharide(LPS)-challenged MCF-10A and MCF-10ACE. Moreover, immunofluorescence and Western bloting were performed to detect the co-localization of CAV-1 and toll-like receptor 4 (TLR4) in human mammary epithelial cells. Results: MCF-10ACE exhibited significant increases in inflammation-associated gene expression, especially IL-6 (~7-fold) and IL6R (~17-fold). In addition, LPS-induced p38 MAPK and JNK MAPK activation was significantly increased in MCF-10ACE. Furthermore, CAV-1 co-localized with TLR4 and appeared a negative correlation trend. Conclusion: CAV-1 gene silencing promotes MAPK activation via TLR4 signaling in human mammary epithelial cells response to LPS.

Genetic characterization of bovine viral diarrhea virus strains in Beijing, China and innate immune responses of peripheral blood mononuclear cells in persistently infected dairy cattle

Xiao Gang Weng,Quan Jiang Song,Qiong Wu,Ming Chao Liu,Meng Ling Wang,Jiu Feng Wang 대한수의학회 2015 Journal of Veterinary Science Vol.16 No.4

To acquire epidemiological data on the bovine viral diarrhea virus (BVDV) and identify cattle persistently infected (PI) with this virus, 4,327 samples from Holstein dairy cows were screened over a four-year period in Beijing, China. Eighteen BVD viruses were isolated, 12 from PI cattle. Based on genetic analysis of their 5’-untranslated region (5’-UTR), the 18 isolates were assigned to subgenotype BVDV-1m, 1a, 1d, 1q, and 1b. To investigate the innate immune responses in the peripheral-blood mononuclear cells of PI cattle, the expression of Toll-like receptors (TLRs), RIG-I-like receptors, interferon-a (IFN-a), IFN-b, myxovirus (influenza virus) resistance 1 (MX1), and interferon stimulatory gene 15 (ISG15) was assessed by qPCR. When compared with healthy cattle, the expression of TLR-7, IFN-a, and IFN-b mRNA was downregulated, but the expression of MX1 and ISG-15 mRNA was upregulated in PI cattle. Immunoblotting analysis revealed that the expression of interferon regulatory factor 3 (IRF-3) and IRF-7 was lower in PI cattle than in healthy cattle. Thus, BVDV-1m and 1a are the predominant subgenotypes in the Beijing region, and the strains are highly divergent. Our findings also suggest that the TLR-7/IRF-7 signaling pathway plays a role in evasion of host restriction by BVDV.
