It is known that in the condition of chemical vapor deposition (CVD) diamond process, molybdenum is capable of forming carbide known as the "glue" which promotes growth of the CVD diamond, and aids its adhesion by (partial) relief of stresses at the interface. Furthermore, the WC grains are...

Empirical investigation results on weighted and un-weighted assortativity, act degree distribution, degree distribution and node strength distribution of nine real world collaboration networks have been presented. The investigations propose that act degree distribution, degree distribution and...

After Xiao et al. [W.-K. Xiao, J. Ren, F. Qi, Z.W. Song, M.X. Zhu, H.F. Yang, H.Y. Jin, B.-H. Wang, Tao Zhou, Empirical study on clique-degree distribution of networks, Phys. Rev. E 76 (2007) 037102], in this article we present an investigation on so-called k-cliques, which are defined as...

We propose describing a kind of cooperation–competition systems by node-weighted bipartite graphs. In such systems the nodes can be divided into two types. One expresses a kind of activities, organizations or events, named “acts”; and another expresses the “actors” participating in...

Urban public traffic networks are typical complex systems. Understanding their evolution mechanism attracts much attention in recent years. Here, we propose that the evolution of urban public traffic network can be considered as a game process between two network manipulators, i.e., passengers...

In this paper we present an empirical study of a few practical systems described by cooperation networks, and propose a model to understand the results obtained. We study four non-social systems, which are the Bus Route Networks of Beijing and Yangzhou, the Travel Route Network of China,...

Systems with simultaneous cooperation and competition among the elements are ubiquitous. In spite of their practical importance, knowledge on the evolution mechanism of this class of complex system is still very limited. In this work, by conducting extensive empirical survey to a large number of...

This paper uses a threshold model to examine a possible threshold effect in the impact of exchange rate volatility on trade volume for the bilateral trade volumes between the US and other G-7 countries. A grid-searching method is used to obtain the threshold points, and time-series econometric...

We develop a theoretical framework to investigate (i) both the determinants and the consequences of auditor conservatism in a capital market setting and (ii) the implications of the Sarbanes-Oxley Act for auditor conservatism and investment efficiency. We derive the following results. First, by...
