This study examines the impact of regional old-age dependency ratio on collection efficiency public pension funds using statistical data contributions schemes for urban employees in 31 Chinese provinces and municipalities between 2010 2015. An inverted U-curve relationship rate was observed with a single threshold value .5439, thus, suggesting need change soft constraints responsibility an opti...

Mormyrogyrodactylus gemini gen. et sp. n. (Gyrodactylidea: Gyrodactylidae), a viviparous monogenean is described from the skin and fins of Marcusenius macrolepidotus (Peters) from South Africa. This new genus is unique in having a large cup-shaped cirrus armed with one large needle-like spine and numerous small hair-like spinelets. A peduncular bar is present. The haptor is clearly demarcated f...

This paper selects three indicators of urbanization, industrial structure and urban-rural income gap to construct a three-dimensional VAR model. Through Granger causality test, impulse response function variance decomposition methods, dynamic analysis urbanization on in Sichuan Province has been carried out. The research shows that: have an important impact the Province. Urbanization present “U...

In this paper, we will propose a nonlinear passivity based controller fur a double inverted pendulum system, consisting of a two-link pendulum mounted on a pad which is moved by a linear induction motor so that the double pendulum points straight-up The proposed controller nut only can drive the double pendulum from its “natural stable hanging position” tu its “unstable upright inverted positio...

This paper selects the panel data of 30 provinces and cities in China from 2009 to 2017, uses threshold effect model investigate non-linear relationship between producer services agglomeration industrial structure upgrading by taking degree lagging one year as variable. The results show that on shows an inverted “U” nonlinear relationship, is, there is optimal level, has a lag.

Energy conservation and environmental protection are crucial to green development. This article distinguishes the relationship between electricity literacy, energy saving awareness information feedback. We found that i) literacy feedback negatively correlated with consumption, ii) there is a positive correlation consumption living area, household income, permanent resident population education ...

The genomes of commonly used variants of human cytomegalovirus (HCMV) strains Towne and AD169 each contain a substantial mutation in which a region (U(L)/b') at the right end of the long unique region has been replaced by an inverted duplication of a region from the left end of the genome. Using high-throughput technology, we have sequenced HCMV strain Towne (ATCC VR-977) and confirmed the pres...

The relationship between state repression and protest is one of the most perplexing in social mobilization theory. Why in some cases does state repression succeed in suppressing organized protest and social movements, while in other cases it only serves to fan the flames of protest? Through various studies, different scholars have proposed and empirically supported contradictory theories that t...
