The understanding of cascading failures in complex systems has been hindered by the lack of realistic large-scale modeling and analysis that can account for variable system conditions. Using the North American power grid, we identified, quantified, and analyzed the set of network components that are vulnerable to cascading failures under any out of multiple conditions. We show that the vulnerab...

The writing can be improved by removing some redundancy though. For example, the findings of the paper are repeated (almost verbatim) four times just in the first two pages of the paper. I wouldn’t mind repeating as long as there are new points to be made, or a different perspective is provided, but this is not the case. Or, Section 2.1 defines what firewalls, IDS devices, and load balancers do...

Quality of care in the United States and elsewhere consistently fails to meet established standards. These failures subject patients to premature death and needless suffering. Yet, unlike the experience with other threats to life (tire failures or airplane rudders), public and private policymakers have been unable to maintain sufficient interest in identifying and solving problems with quality ...

When designing or extending electricity grids, both frequency stability and resilience against cascading failures have to be considered amongst other aspects of energy security and economics such as construction costs due to total line length. Here, we compare an improved simulation model for cascading failures with state-of-the-art simulation models for short-term grid dynamics. Random ensembl...

Submarine channel–levee systems are among the largest sedimentary structures on the ocean floor. These channels have a sinuous pattern and are the main conduits for turbidity currents to transport sediment to the deep ocean. Recent observations have shown that their sinuosity decreases strongly with latitude, with high-latitude channels being much straighter than similar channels near the Equat...

Water resource management and flood forecasting are crucial societal financial stakes requiring reliable predictions of flow parameters (depth, velocity), the accuracy which is often limited by uncertainties in hydrodynamic numerical models. In this study, we assess effect two uncertainty sources, namely breach characteristics induced overtopping roughness coefficient, on water elevations inund...
