The robustness and breakup of spiral wave in a two-dimensional lattice networks of neurons are investigated. The effect of small- world type connection is often simplified with local regular connection and the long-range connection with certain probability. The network effect on the development of spiral wave can be better described by local regular connection and changeable long-range connection probability than fixed long-range connection probability because the long-range probability could be changeable in realistic biological system. The effect from the changeable probability for long-range connection is simplified by multiplicative noise. At first, a stable rotating spiral wave is developed by using appropriate initial values, parameters and no-flux boundary conditions, and then the effect of networks is investigated. Extensive numerical studies show that spiral wave keeps its alive and robust when the intensity of multiplicative noise is below a certain threshold, otherwise, the breakup of spiral wave occurs. A statistical factor of synchronization in two-dimensional array is defined to study the phase transition of spiral wave by checking the membrane potentials of all neurons corresponding to the critical parameters(the intensity of noise or forcing current)in the curve for factor of synchronization. The Hindmarsh-Rose model is investigated, the Hodgkin-Huxley neuron model in the presence of the channel noise is also studied to check the model independence of our conclusions. And it is found that breakup of spiral wave is easier to be induced by the multiplicative noise in presence of channel noise.

Silicon lithium-ion battery anode with enhanced performance： Multiple effects of silver nanoparticles

作者： Shanshan Yin Qing jia Xiuxia Zuo Shuang Xie Kai Fang Yonggao Xia Jinlong Li Bao Qiu Meimei Wang jianzhen Ban Xiaoyan Wang Yi zhang Ying Xiao Luyao Zheng Suzhe Liang Zhaoping Liu Cundong Wang ya-jun Cheng Ningbo Institute of materials technology and Engineering Chinese Academy of Sciences Ningbo 315201 China North university of china Taiyuan 030051 China The university of Nottingham Ningbo china Ningbo 315100 China Nano Science and technology Institute University of Science and Technology of China Suzhou 215123 China department of materials University of Oxford Parks Rd.

Silicon has been regarded as one of the most promising next generation lithium-ion battery anode. How- ever, the poor cyclic stability of the Si based anode has severely limited its practical applications, which is even worse with high mass loading density （〉1 mg cm^-2 ）. A new concept has been developed to enhance the electrochemical performance of the Si nanoparticle anode. Silver nanoparticles are composited with the silicon nanoparticles in a facile way for the first time. It is found that the mechanical properties of the Si electrode have been significantly improved by the incorporation of the silver nanoparticles, leading to enhanced cyclic performance. With the Si/Ag mass ratio of 4：1, the reversible specific discharge capacity is retained as l 156 ma h g^-1 after 100 cycles at 200 mag^-1, which is more than three times higher than that of the bare silicon （318 ma h g^-1 ）. The rate performance has been effectively improved as well due to excellent electron conductivity of the silver nanoparticles.
