In this study, a simple hydrothermal method has been developedto prepare Ti3C2Tx from Ti3AlC2 as a high-performance electrodematerial for supercapacitors. This method is environmentallyfriendly and has a low level of danger. The morphology andstructure of the Ti3C2Tx can be controlled by hydrothermalreaction time, temperature and NH4F amounts. The preparedTi3C2Tx was characterized by X-ray diffraction, field emissionscanning electron microscopy, Raman spectroscopy, X-rayphotoelectron spectroscopy and Brunauer-Emmet-Teller. Theresults show that the prepared Ti3C2Tx is terminated by O, OH,and F groups. The electrochemical properties of the Ti3C2Txsample exhibit specific capacitance up to 141 Fcm−3 in 3 MKOH aqueous electrolyte, and even after 1000 cycles, nosignificant degradation of the volumetric capacitance wasobserved. These results indicate that the Ti3C2Tx materialprepared by this hydrothermal method can be used in highperformance supercapacitors.

优秀的电影字幕翻译是电影传播的关键所在,奈达主张的功能对等理论强调译文对原文的再现。本文以《哪吒之魔童降世》的维吾尔语翻译版为例,在词汇、句法和语音三个层面从功能对等理论的视角对其字幕维译进行探赜,例举了译文存在的问题并提出了相应的对策。研究发现功能对等理论能够较为全面地分析电影字幕维吾尔语翻译,为译者提高翻译水平提供参考。 The secret to effective film communication is excellent film subtitle translation. The reproduction of the original text is emphasized by Eugene A. Nida’s functional equivalence theory. This paper explores the movie subtitle translation from the standpoint of functional equivalence theory at the lexical, syntactic, and phonetic levels, using the Uyghur translation of “Nezha: Birth of the Demon Child” as an example. It then illustrates the issues with the translation and suggests solutions. The study found that functional equivalence theory can examine the Uyghur translation of movie subtitles thoroughly and offer guidelines for translators to raise the quality of their work.

Feng Ye,Yan Qiu,Li Li,Libo Yang,Fei Cheng,Hongying Zhang,Bing Wei,Zhang Zhang,Linyong Sun,Hong Bu 한국유방암학회 2015 Journal of breast cancer Vol.18 No.3

Purpose: It is well established that breast cancer stem cells (BCSCs) play an essential role in tumor invasion for both local and distant metastasis. The aim of this study was to establish whether BCSCs could act as a prognostic and clinical marker. Methods: We analyzed tumor tissues from 161 breast cancer patients. Dual immunohistochemistry and immunofluorescence were performed on all the slides, and we analyzed the relationship between EpCAM–/CD49f+ tumor cells and key clinical and prognostic factors. Results: Univariate survival analysis using the Kaplan-Meier method showed that the presence of EpCAM–/ CD49f+ tumor cells in breast cancer was significantly associated with shorter disease-free survival (DFS) and overall survival (OS). Multivariate analysis showed that the presence of EpCAM–/ CD49f+ cells was associated with shorter DFS (p=0.010; hazard ratio [HR], 2.070) and OS (p=0.002; HR, 3.235). Tumors containing EpCAM–/CD49f+ cells were also more likely to metastasize after initial surgery (p=0.048). Conclusion: Our study suggests that breast tumors containing EpCAM–/CD49f+ cells are more likely to undergo distant metastasis after initial surgery and are associated with a shorter DFS and OS.

Research on IT Capability Matching Based on Compatibility

Zhang tao,Yang libo 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.10

IT capability based on RBV cannot provide firms with durative competitive advantage. IT capability consists of basic IT capability and critical IT capability. Meaning alignment of IT capability is that firm will select optimal basic IT capability compatibility according to difference of critical IT capability between two firms. This paper used Stackelberg model to research alignment of IT capability factors based on consumer theory. When difference of critical IT capability between firms is significant, the incumbent firm should control compatibility of basic IT capability, which enable him to achieve differentiation competitive advantage; when difference of critical IT capability between firms is insignificant, incumbent firm should open IT criterion absolutely, which can increase consumers’ anticipation to achieve installed-base for technological innovation. Two kinds of competitive can transform each other, which enable competitive advantage to be persistence and dynamic.

Research on IT Capacity Matching between Enterprises Based on Vertical Value Chain

Zhang Tao,Yang Libo 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.12

The IT capacity based on the resource-based view could not bring sustainable competitive advantages to the enterprise.IT capacity is composed of the critical IT capacity and standard IT capacity; whether the enterprise could obtain the sustainable competitive advantage depends on the IT capacity matching of the enterprise. From the perspective of vertical market, with the help of Stackelberg model, the paper studies the influence of the network externality of standard IT capacity in components market on the competitive advantage of the total product enterprise. When the intensity of network externality of standard IT capacity in components increases, the change in the price of the inplace total product is uncertain; however, it always has positive feedback on the market demand of inplace total product, which makes the earnings from inplace total product increase continuously, resulting in the whole market in imbalance.

To improve the bile salt and acid tolerance of probiotics against gastrointestinal stresses, we investigated the effects of soybean lecithin and whey protein concentrate (WPC) 80 on the bile salt tolerance of Lacticaseibacillus paracasei L9 using a single-factor methodology, which was optimized using response surface methodology (RSM). The survival rate of L. paracasei L9 treated with 0.3% (w/v) bile salt for 2.5 h, and combined with soybean lecithin or WPC 80, was lower than 1%. After optimization, the survival rate of L. paracasei L9 incubated in 0.3% bile salt for 2.5 h reached 52.5% at a ratio of 0.74% soybean lecithin and 2.54% WPC 80. Moreover, this optimized method improved the survival rate of L. paracasei L9 in low pH condition and can be applied to other lactic acid bacteria (LAB) strains. Conclusively, the combination of soybean lecithin and WPC 80 significantly improved the bile salt and acid tolerance of LAB. Our study provides a novel approach for enhancing the gastrointestinal tolerance of LAB by combining food-derived components that have different properties.

Chen Wang,Libo Ding,He Zhang,Li Xiao,Shihao Zhang 한국항공우주학회 2022 International Journal of Aeronautical and Space Sc Vol.23 No.1

Isolated rotating tail rudder technology provides a low-cost and miniaturized solution for the correction and guidance of a man-portable rocket. The results of three turbulence models (the Spalart–Allmaras model, standard k–ε model, and shear stress transport k–ω model) were compared with wind-tunnel model test data, and the best turbulence model was selected. An aerodynamic model of the rotating tail rudder was developed by identifying its turbulent region, and the influences of the Mach number, angle of attack, and tail rudder speed on the projectile aerodynamics were revealed. The aerodynamic parameters were fitted using a least-squares method, and the vector variation characteristics of the period-averaged control force were analyzed. The results from the shear stress transport k–ω model were closest to the results of the wind-tunnel tests. The aerodynamic model was able to fit the simulation results well. The average control force of the tail rudder over a rotation cycle is not zero, and it increases with increasing angle of attack, Mach number, and tail rudder rotation speed. This study provides a basis for aerodynamic research examining the same type of projectile, and it has guiding significance for the control design of isolated rotating tail rockets.
