When an initial failure of nodes occurs in interdependent networks, a cascade of failure between the networks occurs. Earlier studies focused on random initial failures. Here we study the robustness of interdependent networks under targeted attack on high or low degree nodes. We introduce a general technique which maps the targeted-attack problem in(More)
It was recently found that cascading failures can cause the abrupt breakdown of a system of interdependent networks. Using the percolation method developed for single clustered networks by Newman [Phys. Rev. Lett. 103, 058701 (2009)], we develop an analytical method for studying how clustering within the networks of a system of interdependent networks(More)
As economic entities become increasingly interconnected, a shock in a financial network can provoke significant cascading failures throughout the system. To study the systemic risk of financial systems, we create a bi-partite banking network model composed of banks and bank assets and propose a cascading failure model to describe the risk propagation(More)
Understanding the complex nature of financial markets remains a great challenge, especially in light of the most recent financial crisis. Recent studies have investigated large data-sets of financial markets, and have analysed and modelled the static and dynamic behaviour of this very complex system (Fama 1965, Lo and Craig MacKinlay 1990, Campbell et al.(More)
Due to a typesetting error, both the authors’ affiliations and the citation in the PDF are incorrect. For the author Irena Vodenska, ‘‘Center for finance, law and policy, Boston University, Boston, Massachusetts 02215 USA’’ was incorrectly listed as a current address rather than an affiliation. This error has now been corrected in the original Article.(More)
Toll-like receptor-4 (TLR4) signaling has been implicated in innate immunity and acute inflammation following acute lung injury (ALI). As such, modulating inflammatory response through TLR4 represents an attractive therapeutic approach to treat ALI. Increasing evidence demonstrates that hyaluronan (HA) can modulate TLR4 activation and has shown early(More)
Clustering, or transitivity, a behavior observed in real-world networks, affects network structure and function. This property has been studied extensively, but most of this research has been limited to clustering in single networks. The effect of clustering on the robustness of coupled networks, on the other hand, has received much less attention. Only the(More)
Complex networks appear in almost every aspect of science and technology. Previous work in network theory has focused primarily on analyzing single networks that do not interact with other networks, despite the fact that many realworld networks interact with and depend on each other. Very recently an analytical D. Y. Kenett (B) · J. Gao · X. Huang · S. Shao(More)
The robustness of complex networks against node failure and malicious attack has been of interest for decades, while most of the research has focused on random attack or hub-targeted attack. In many real-world scenarios, however, attacks are neither random nor hub-targeted, but localized, where a group of neighboring nodes in a network are attacked and(More)
The influence of directors has been one of the most engaging topics recently, but surprisingly little research has been done to quantitatively evaluate the influence and power of directors. We analyze the structure of the US corporate governance network for the 11-year period 1996-2006 based on director data from the Investor Responsibility Research Center(More)
