Liu Jian(Jian Liu),Fei Jingying(Jingying Fei),Lv Mingkang(Mingkang Lv) 아시아사회과학학회 2022 International Science Research Vol.2 No.3

In recent years, a large number of excellent foreign short video bloggers have been active on major social media platforms, comparing the differences between Chinese and Western cultures, introducing Chinese traditional culture and customs to followers, and becoming a new force in telling Chinese stories. This paper takes the short video blogger “Chris” and his short videos as the research object, and analyze how “foreign influencer” tells Chinese stories in the new media environment, which brings new inspiration for telling Chinese stories and spreading Chinese voices well in the new media environment.

Vertical Vibration of Strip Mill with the Piecewise Nonlinear Constraint arising from Hydraulic Cylinder

Fei Liu,Bin Liu,Hao-ran Liu,Yan-ling Gong,Song-jun Wang 한국정밀공학회 2015 International Journal of Precision Engineering and Vol. No.

Vertical vibration model of strip mill is established by considering piecewise nonlinear constraint arising from hydraulic cylinder. The approximate analytical solution of the model is obtained by incremental harmonic balance (IHB) method. The harmonic frequencies not conducive to stability are produced because the nonlinearity of the piecewise constraint. Bifurcation behavior of the system changes with external excitation amplitude and frequency ratio, intermittent chaos and periodic window are appeared alternately, the chaos region enlarged with the increasing piecewise interval. Compared with the piecewise linear constraint, the region of chaotic motion is widened obviously under the nonlinear constraint. Moreover, the critical condition of bifurcation and chaos behavior can be obtained from maximum Lyapunov exponent (MLE).

Fei Li,Xin-ji Li,Li Qiao,Fei Shi,Wen Liu,You Li,Yu-ping Dang,Weijie Gu,Xiao-gang Wang,Wei Liu 생화학분자생물학회 2014 Experimental and molecular medicine Vol.46 No.-

Dysregulated microRNA (miRNA) expression has a critical role in tumor development and metastasis. However, the mechanism by which miRNAs control melanoma metastasis is unknown. Here, we report reduced miR-98 expression in melanoma tissues with increasing tumor stage as well as metastasis; its expression is also negatively associated with melanoma patient survival. Furthermore, we demonstrate that miR-98 inhibits melanoma cell migration in vitro as well as metastatic tumor size in vivo. We also found that IL-6 is a target gene of miR-98, and IL-6 represses miR-98 levels via the Stat3-NF-κB-lin28B pathway. In an in vivo melanoma model, we demonstrate that miR-98 reduces melanoma metastasis and increases survival in part by reducing IL-6 levels; it also decreases Stat3 and p65 phosphorylation as well as lin28B mRNA levels. These results suggest that miR-98 inhibits melanoma metastasis in part through a novel miR-98-IL-6-negative feedback loop.

Characteristics of Diprophylline-Induced Bidirectional Modulation on Rat Jejunal Contractility

Liu, Fang-Fei,Chen, Da-Peng,Xiong, Yong-Jian,Lv, Bo-Chao,Lin, Yuan The Korean Society of Pharmacology 2014 The Korean Journal of Physiology & Pharmacology Vol.18 No.1

In this study, we propose that diprophylline exerts bidirectional modulation (BM) on the isolated rat jejunal segment depending on its contractile state. The results supported the hypothesis. Diprophylline ($20{\mu}M$) exerted stimulatory effects on the contractility of jejunal segment in six low contractile states while inhibitory effects in six high contractile states, showing the characteristics of BM. Diprophylline-induced stimulatory effect was significantly blocked by atropine, indicating the correlation with cholinergic activation. Diprophylline-induced inhibitory effect was partially blocked by phentolamine, propranolol, and L-N-Nitro-Arginine respectively, indicating their correlation with sympathetic activation and nitric oxide-mediated relaxing mechanisms. Diprophylline-induced BM was abolished by tetrodotoxin or in a $Ca^{2+}$ free condition or pretreated with tyrosine kinase inhibitor imatinib, suggesting that diprophylline-induced BM is $Ca^{2+}$ dependent, and that it requires the presence of enteric nervous system as well as pacemaker activity of interstitial cells of Cajal. Diprophylline significantly increased the reduced MLCK expression and myosin extent in constipation-prominent rats and significantly decreased the increased MLCK expression and myosin extent in diarrhea-prominent rats, suggesting that the change of MLCK expression may also be involved in diprophylline-induced BM on rat jejunal contractility. In summary, diprophylline-exerted BM depends on the contractile states of the jejunal segments, requires the presence of $Ca^{2+}$, enteric nervous system, pacemaker activity of interstitial cells of Cajal, and MLCK-correlated myosin phosphorylation. The results suggest the potential implication of diprophylline in relieving alternative hypo/hyper intestinal motility.

Fei Liu,Chenghao Zeng,Liang Cheng,Yunze He,Yun Bai,Xuefeng Geng,Songyuan Liu,Dantong Ren,Lei Wang 전력전자학회 2022 JOURNAL OF POWER ELECTRONICS Vol.22 No.12

Unlike conventional voltage and current sensing, this paper studies the use of acoustic emission signals to detect the condition of the power device for a DC–AC inverter. As a relatively new method for monitoring power devices, there are some unknown phenomena in acoustic emissions (also called mechanical stress wave). Therefore, the authors present an experimental setup that is used to analyze acoustic emission signals. Based on experimental results, some interesting points have been found: (1) The generation of a mechanical stress wave is verified for the first time. (2) The time-domain peak value, energy, and rise time of the mechanical stress wave at the turn-on time of a power device are barely affected by the load. Meanwhile, these values decrease with an increase of the load at the turn-off time. (3) The frequency-domain peak value of the mechanical stress wave tends to decrease with an increase of the load, and the peak frequency is barely affected by the load. These mechanical stress analysis results can be utilized for condition monitoring in many applications.

한중 동물 속담의 문화적 의미 대조

Liu Xue Fei 한국어교육연구학회 2018 한국어교육연구 Vol.- No.9

옛날부터 동물과 인류는 관계(인연)를 깊이 맺어오고 있었기 때문에 인류의 생산과 생활 관계가 매우 밀접하다. 동시에 동물에 관한 속담은 오랫동안 민족의 정신문화에도 큰 영향을 미쳤다. 이번 논문에서는 한국과 중국의 동물에서 나타나는 출현 빈도가 높은 동물 속담을 조사하여 두 나라 사이의 언어와 문화이동 사례를 비교하고 분석해 보고자 한다. 한중 양국 동물에 관한 속담을 통해서 양국의 농사, 기후, 풍속, 생활습관과 욕 문화 등의 다양한 문화 차이를 볼 수 있다. 이를 통해서 또한 양국인의 사고방식과 언어 습관의 공통점과 차이점도 볼 수 있다. 본 논문은 한국어를 배우는 중국인, 중국어를 배우는 한국인에게 작은 도움이 될 수 있을 것이 바란다. 특히 오늘날과 같이 교류 현상이 두드러지고 있는 현실을 감안할 때에 이 연구의 필요성은 절실하다. Some of the Korean language norms, even if they are intended to be used by Korean users correctly, have a high incidence of the spelling errors due to the problem of regulation itself. An example is the more complicated and more cryptic rules by allowing different allomorph for forms that appear to have the same basic morpheme. Even if these regulations take maximum consideration of the characteristics of Korean language, there is a high possibility that the user will cause a spelling error from the beginning, compared to the simple rules. The purpose of this paper is to investigate the effect of the complexity of Korean language norms on the errors of the users spelling. In order to accomplish this purpose, this paper collected and analyzed errors in three types of morphemes which are spelled Korean users. As a result, the spelling error rate of Korean users was found to be very high. For example, in the case of ‘neolttarata’, the error rate is 211.8%, in the case of ‘subeol’, the error rate is 75%, in the case of ‘wicheung’, the error rate is 97.1%, compared to the correct spelling. This paper will be useful for revising related Korean language norms, which can improve the convenience and accuracy of spelling of Korean users in the future by verifying empirically the cases.

Control of Single-Molecule Junction Conductance of Porphyrins via a Transition-Metal Center

Liu, Zhen-Fei,Wei, Sujun,Yoon, Hongsik,Adak, Olgun,Ponce, Ingrid,Jiang, Yivan,Jang, Woo-Dong,Campos, Luis M.,Venkataraman, Latha,Neaton, Jeffrey B. American Chemical Society 2014 NANO LETTERS Vol.14 No.9

<P>Using scanning tunneling microscope break-junction experiments and a new first-principles approach to conductance calculations, we report and explain low-bias charge transport behavior of four types of metal–porphyrin–gold molecular junctions. A nonequilibrium Green’s function approach based on self-energy corrected density functional theory and optimally tuned range-separated hybrid functionals is developed and used to understand experimental trends quantitatively. Importantly, due to the localized d states of the porphyrin molecules, hybrid functionals are essential for explaining measurements; standard semilocal functionals yield qualitatively incorrect results. Comparing directly with experiments, we show that the conductance can change by nearly a factor of 2 when different metal cations are used, counter to trends expected from gas-phase ionization energies which are relatively unchanged with the metal center. Our work explains the sensitivity of the porphyrin conductance with the metal center via a detailed and quantitative portrait of the interface electronic structure and provides a new framework for understanding transport quantitatively in complex junctions involving molecules with localized d states of relevance to light harvesting and energy conversion.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2014/nalefd.2014.14.issue-9/nl5025062/production/images/medium/nl-2014-025062_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl5025062'>ACS Electronic Supporting Info</A></P>

Lack of any Association between Insertion/Deletion (I/D) Polymorphisms in the Angiotensin-converting Enzyme Gene and Digestive System Cancer Risk: a Meta-analysis

Liu, Jin-Fei,Xie, Hao-Jun,Cheng, Tian-Ming Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.12

Objective: To investigate the association between the gene polymorphisms of angiotensin-converting enzyme (ACE) and digestive system cancer risk. Method: A search was performed in Pubmed, Medline, ISI Web of Science and Chinese Biomedical (CBM) databases, covering all studies until Sep 1st, 2013. Statistical analysis was performed by using Revman5.2 and STATA 12.0. Results: A total of 15 case-control studies comprising 2,390 digestive system cancer patients and 9,706 controls were identified. No significant association was found between the I/D polymorphism and digestive cancer risk (OR=0.93, 95%CI = (0.75, 1.16), P=0.53 for DD+DI vs. II). In the subgroup analysis by ethnicity and cancer type, no significant associations were found for the comparison of DD+DI vs. II. Results from other comparative genetic models also indicated a lack of associations between this polymorphism and digestive system cancer risks. Conclusions: This meta-analysis suggested that the ACE D/I polymorphism might not contribute to the risk of digestive system cancer.

Expression and Prognostic Implications of FOXO3a and Ki67 in Lung Adenocarcinomas

Liu, Hong-Bin,Gao, Xiang-Xiang,Zhang, Qing,Liu, Jian,Cui, Yuan,Zhu, Yan,Liu, Yi-Fei Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.4

To investigate the significance of FOXO3a and Ki67 in human lung adenocarcinomas. Envision immunohistochemical staining and Western blotting were used to examine the protein expression of FOXO3a in 127 cases of human lung adenocarcinoma specimens. The positive rate in lung adenocarcinoma (55.9%) was lower than that in normal tissues (80%). We found that the expression of FOXO3a was closely related with the degree of differentiation, TNM staging, lymph node metastasis and survival. In addition, significant differences in the different pathological types of lung adenocarcinoma cases (P<0.01). The FOXO3a positive rate of the acini as the main type (APA) (86.7%) and the lepidic as the main type (LPA) (82.4%) was higher than the solid as the main type (SPA) (50.0%), the papilla as the main type (PPA) (42.9%) and the micropapilla as the main type (MPA) (9.4%). Moreover, the expression of FOXO3a was negatively related with Ki67 expression. Our results suggested that the expression of FOXO3a is closely correlated with the aggressiveness of lung adenocarcinoma. It was indicated that disregulation of FOXO3a might play key roles in the occurrence and development of lung a denocarcinoma and joint detection of the two markers might play an important role in diagnosing tumors.
