Cascaded failures in weighted networks
Physical Review E, 2011Many technological networks can experience random and/or systematic failures in their components. More destructive situations can happen if the components have limited capacity, where the failure in one of them might lead to a cascade of failures in other components, and consequently break down the structure of the network. In this paper, the tolerance

A problem that has plagued market failure discussions is: "why does bad policy exist and persist?" Various schools of thought have answered that question, but I argue that the explanations, while correct, are incomplete. In this paper, I apply the expert failure literature to the problem of economic policy discussions to show that 1) failed advice can ...

Journal of Institutional Economics, 2022
AbstractRecent research has shown how experts may fail in their duty as advisors by providing advice that leads to a worse outcome than that anticipated by the user of expert opinion. However, those models have focused on the immediate effects of the failure on experts and nonexperts.

Blackouts and Cascading Failures
Scientific American, 2009The editorial presents the author's thoughts regarding the process of cascading failure behind the 2008-2009 global economic crisis. The need to apply lessons learned from the cascading nature of the economic crisis to other systemic threats, such as those presented by the crises of water shortage, energy shortage, and poverty, is also discussed.

ON THE OUTCOME OF A CASCADING FAILURE MODEL
Probability in the Engineering and Informational Sciences, 2006This article is concerned with a loading-dependent model of cascading failure proposed recently by Dobson, Carreras, and Newman [6]. The central problem is to determine the distribution of the total number of initial components that will have finally failed. A new approach based on a closed connection with epidemic modeling is developed.

Cascading failures of wireless sensor networks
Proceedings of the 11th IEEE International Conference on Networking, Sensing and Control, 2014Despite the fact that the research related to the invulnerability of wireless sensor networks (WSNs) has made gratifying progress, most of it focuses on their topology tolerance but fails to consider the impact of traffic load and energy consumption on their invulnerability.

The lung water cascade in heart failure
Echocardiography, 2017In heart failure patients, we hypothesize the occurrence of the “lung water cascade,” with the various markers hierarchically ranked in a well‐defined time sequence: (1) early, proximal hemodynamic event with increase in pulmonary capillary wedge pressure; (2) intermediate, direct imaging sign of pulmonary edema (easily detectable at bedside by lung ...

A Markovian Dependability Model with Cascading Failures
IEEE Transactions on Computers, 2009We develop a continuous-time Markov chain model of a dependability system operating in a randomly changing environment and subject to probabilistic cascading failures. A cascading failure can be thought of as a rooted tree. The root is the component whose failure triggers the cascade, its children are those components that the root's failure ...
