In the digital age, Internet use has become important for relative poverty governance and common prosperity in China. “Internet + targeted poverty alleviation” is an essential boost to poverty alleviation that has experienced empirical tests. Academics have also paid attention to the poverty reduction effect of Internet use. On the one hand, existing studies mainly focus on its effect in rural areas, while relative poverty exists widely between urban and rural areas. Therefore, further comparison of the urban-rural differences in their poverty reduction effect is necessary. On the other hand, promoting capital accumulation is the fundamental mechanism of the poverty reduction effect of Internet use, which academics have poorly analyzed. Using the Chinese General Social Survey(CGSS)data in 2017, this paper uses the moderating effect, mediating effect, moderated mediating effect, and threshold effect models to examine the poverty reduction effect of Internet use and the urban-rural difference in its capital accumulation mechanism. The results find that Internet use can alleviate the relative poverty of individuals and has a more significant effect on rural residents than urban residents. Moreover, the results remain robust after overcoming the endogeneity problem using the instrumental variables model. Further mechanism analysis reveals that Internet use can transform online resources into offline human, social, and economic capital, thus alleviating relative poverty. Among them, the poverty reduction effect of human capital accumulated by Internet use is stronger for urban residents, and the poverty reduction effect of economic capital is more substantial for rural residents. Meanwhile, there are threshold conditions for human capital, economic capital, and social capital for the poverty reduction effect of Internet use. Furthermore, there are urban-rural differences in the threshold values. The contribution of this paper to the existing research lies in the following aspects: first, it places urban and rural residents in the same framework and uses different poverty measurement criteria to compare the differences in poverty reduction effects generated by Internet use. Second, to break the dichotomy method used in previous poverty studies, this paper pays more attention to the relative characteristics of relative poverty, takes the difference degree between individual living standard and average level as the index of relative poverty measurement, and generates the variable of relative poverty depth, which is an innovation of poverty measurement. Third, it reveals that the accumulation effect of capital(economic, social, and human capital)generated by Internet use is the fundamental poverty reduction mechanism and further analyzes its urban-rural heterogeneity and threshold conditions. The results suggest that, on the whole, Internet use has a more significant poverty reducing effect on rural residents than on urban residents. Thus vigorous development of Internet infrastructure in rural areas remains an important initiative for future relative poverty governance. The accumulation of human capital is the fundamental mechanism of Internet poverty reduction, warning us to pay attention to enhancing human capital. The top priorities for future poverty governance are relatively poor residents in urban areas and relatively poor “marginal” populations in rural areas. [ABSTRACT FROM AUTHOR]

In order to provide a reference for the galloping characteristics and anti-vibration of the ice-coated eight-bundle transmission line, the phenomenon and characteristics of the sub-span oscillation of the eight-bundle conductor were analyzed by numerical analysis, and the numerical simulation results were compared to find the movement trajectory and similarities and differences in galloping amplitude. The results show that the sub-conductors of the iced eight-bundle transmission line dance in the same direction under different wind speeds. However, due to the influence of wake interference and aerodynamic loads, the vibration amplitudes of the sub-conductors under different wind speeds are different. The limit of the diagram is an oblique ellipse. It can be seen that the sub-span oscillation during the galloping process of the iced eight-bundle conductor may cause the sub-conductor to collide, which harms the safe operation of the ultra-high voltage(UHV) transmission line. The research results have certain reference significance for the follow-up research on galloping principle and anti-vibration of UHV transmission lines. [ABSTRACT FROM AUTHOR]

MicroRNA(miRNA)affect various biological processes such as cell differentiation, proliferation, and apoptosis by inhibiting the translation of target genes after transcription and are widely involved in the regulation of immune and inflammatory responses in organisms. Autoimmune liver diseases are a group of chronic inflammatory diseases of the hepatobiliary system mediated by abnormal immunity, and abnormal immune inflammatory response of liver tissue with the involvement of miRNA is closely associated with the development and progression of autoimmune liver diseases. This article reviews the current research advances in miRNA in autoimmune liver diseases. [ABSTRACT FROM AUTHOR]

Plant pathogenic oomycetes could cause many devastating diseases. Currently, chemical control is still one of the most effective methods for the control of oomycete diseases. However, many fungicides against oomycetes have generated serious resistance problems because of unreasonable and frequent applications in fields. The mode of action, resistant genetic mechanism and molecular resistance mechanism of several most commonly used fungicides were reviewed, such as phenylamides (PAs), carboxylic acid amides (CAAs), quinone outside inhibitors (QoIs), oxysterol binding protein inhibitors (OSBPIs) and tubulin inhibitors. The current knowledge summaried in this review will contribute to the scientific control of plant pathogenic oomycetes and provide a valuable reference for future research. Existing literature reports demosntaretd that point mutation in target protein could cause resistance to PAs, CAAs, QoIs, OSBPIs and tubulin inhibitors. PAs and tubulin inhibitors resistance were controlled by more than one gene, and QoIs resisitance was maternal inheritance. It was speculated that OSBPIs resistance was controlled by one dominant gene. However, there was distinct difference in genetic mechanism for different CAAs fungicides. [ABSTRACT FROM AUTHOR]

Due to the influence of the land roughness, the lower the wind load, the higher turbulence intensity of wind. According to wind tunnel tests, it can be found that the aerodynamic coefficients of iced 8-bundled conductor are significantly different under different turbulence conditions, and the Den Hartog and Nigol coefficients determined by aerodynamic coefficients are also different. Based on the test results, the numerical analysis of the galloping of iced 8-bundled conductor is analyzed, and the response of galloping to the change of turbulence is investigated. The mathematical simulation results of galloping traces show that the galloping amplitudes of the iced conductors and the range of initial attack angle increase obviously under turbulence conditions. Moreover, the effects of different parameters on the galloping of iced 8-bundled conductors are researched. The parameters such as wind velocity, attack angle, and span length on the galloping of the 8-bundled conductors under turbulence wind loads are obtained by numerical method, which offers a theoretical basis for the study of the technique of anti-galloping.

Wake-induced galloping is a high risk for a safe operation of electrical transmission system due to dense arrangement of sub-conductors in multi-bundle conductors. To investigate the wake-induced galloping characteristics of eight bundle conductors with extra-high voltage, the variation of aerodynamic forces of each sub-conductor in the eight bundle conductors changing with angle of attack was tested by wind tunnel tests. Because of the wake interaction within subconductors, a relatively distinguishable difference can be observed among the aerodynamic forces of the eight conductors. Especially, when a leeward sub-conductor is in the wake of windward sub-conductor, the drag exerted on the leeward conductor significantly drops. The wake-induced galloping of eight bundle conductors with two span-lengths 308 m and 405 m was numerically simulated by the ABAQUS software. Based on the simulation results, a critical wind speed has been found for the wake-induced galloping. The galloping will not take place when the wind speed is lower than the critical speed. The motion orbit of the sub-conductor is elliptical with wake-induced galloping. Given the same wind speed, the amplitude of the galloping with long span-length is greater than that with short span-length. [ABSTRACT FROM AUTHOR]
