Many networks are characterized by highly heterogeneous distributions of links which are called scale-free networks, and the degree distributions follow p(k)∼ck-α. We study the robustness of scale-free networks to random failures from the character of their heterogeneity. Entropy of the...

Renewable energy development is a major response to address the issues of climate change and energy security. The utilization of renewable resources, however, highly depends on the climate conditions, which may be impacted in the future due to global climate change. Based on literature analysis,...

Environmental regulation has become more and more important in policy making among the world economies. How has it affected productivity growth and hence economic growth? The answer to this question is either controversial or yet to be explored in many cases. The objective of this paper is to...

We examine the association between auditor choice and the accruals patterns of Chinese listed firms that cross-list in Hong Kong. Our evidence suggests that the clients of Big 4 auditors report lower unsigned discretionary accruals relative to the clients of non-Big 4 auditors. Further, we find...

Tsinghua University, one of the top universities in China, has conducted a lot of collaborative R&D projects with multinational companies in the recent years. One of tough issues in the collaborative R&D is to deal with the intellectual property rights. The Chinese Patent Law and other relevant...

As a calcium oscillations system is in steady state, the effects of colored noise and noise delay on the system is investigated using stochastic simulation methods. The results indicate that: (1) the colored noise can induce coherence bi-resonance phenomenon. (2) there exist three peaks in the...
