The dynamics of two-word naming game incorporating the influence of biased assimilation is investigated in this paper. Firstly an extended naming game with biased assimilation（NGBA） is proposed. The hearer in NGBA accepts the received information in a biased manner, where he will refuse to accept the conveyed word with a predefined probability, if it is different from his own current memory. Secondly, the adaptive network is formulated, where the existing links may be reconnected so that the individual can influence other individuals over the population as much as possible. Numerical simulation results show that the population in NGBA can eventually reach consensus;the larger strength of biased assimilation on both words, the slower convergence speed, while larger strength of biased assimilation on only one word can slightly accelerate the convergence;larger population size can make the rate of convergence slower to a large extent when it increases from relatively small size, but such effect becomes minor when the population size is large;the behavior of adaptively reconnecting the existing links can greatly accelerate the rate of convergence.

This paper presents a sensorless control strategy for the surface-mounted permanent magnet synchronous motors（SPMSMs） with a sliding mode controller（SMC）.To extract accurate rotor position from the back electromotive force（EMF） of the SPMSM,a tangent function-based phase-locked loop（PLL） is *** extra tuning of parameters,the position estimation scheme manages to provide accurate rotor position under both forward and reverse rotational *** to conventional sliding mode control approach,the proposed SMC adopts a nonlinear reaching law,which helps the controller to simultaneously achieve faster reaching time and lower chattering *** of the proposed control strategy is verified by simulation results.

Countries in the world have formed a huge network by international investment and trade, where economic turmoil in some areas may lead to a worldwide financial crisis. In this paper, based on the international investment and trade data of155 countries from 2007 to 2010, a double-layer network is constructed to analyze the economic crisis’ s influence that how countries’ economic situation evolves over time and affects each other. First, an improved epidemic model is developed on the double-layer network, where each country possesses three candidate states including susceptible, contagious and ***, Debt Rank of each layer is calculated to quantify the propagation of financial distress and crisis, which shows that Debt Rank is basically consistent with the GDP of countries, and countries with small Debt Rank are more vulnerable in trade network, while countries with big Debt Rank are more vulnerable in investment network.

In this paper, from a perspective of complex network, we investigate the international trade and investment for more than 200 countries from 2001 to 2010. Through analyzing the topological properties, we nd that the average partner numbers for both trade and investment are increasing year by year, and the average volume has a signi cant decrease in 2008 for investment and 2009 for trade. Although the edge density is dramatically lower and the average path length is longer for the international investment network, its clustering coef cient is higher every year. Moreover, we detect community structures and rank each country according to its total trade or investment volume, which demonstrate that the partnerships for the international trade are more stable, and USA always ranks rst in its community for both trade and investment.
