In short, it does not account for abundance in the distribution of species and their functional roles within and across the scales of a system.  ...  The cross-scale resilience model suggests that system-level ecological resilience emerges from the distribution of species' functions within and across the spatial and temporal scales of a system.  ...  The views expressed in this article are those of the authors and do not necessarily represent the views or policies of the U.S. Environmental Protection Agency or the U.S. Fish and Wildlife Service.  ...

A High-Level Policy Description Language for the Network ACL [chapter]

Jangha Kim, Kanghee Lee, Sangwook Kim, Jungtaek Seo, Eunyoung Lee, Miri Joo
2004 Lecture Notes in Computer Science  
Since the network is not available, it becomes hard to serve a node with an order. It is difficult for most large networks to introduce a consistent monitoring tool and reporting system.  ...  Malicious codes and worms comprise the largest portion of the loss caused the security problem in the Internet. Small worms such as the "Blaster" spread quickly through the enormous network.  ...  In constructing hierarchal Domains in the large-scale network, each Domain is recursively constructed.  ...

Voter model dynamics in complex networks: Role of dimensionality, disorder, and degree distribution

Krzysztof Suchecki, Víctor M. Eguíluz, Maxi San Miguel
2005 Physical Review E  
The existence of hubs in the network modifies the linear system size scaling law of the survival time.  ...  We also find that when there is no ordering in the system, the average survival time of metastable states in finite networks decreases with network disorder and degree heterogeneity.  ...  Role of degree distribution To address the question of the role of the degree distribution of the network in the voter model dynamics we compare the evolution in networks with a scale-free degree distribution  ...

Granularity and Inhomogeneity Are the Joint Generators of Optical Rogue Waves

F. T. Arecchi, U. Bortolozzo, A. Montina, S. Residori
2011 Physical Review Letters  
These two features characterize also rogue waves in nonlinear systems; thus, nonlinearity just plays the role of bringing forth the two ingredients of granularity and inhomogeneity.  ...  In the presence of many waves, giant events can occur with a probability higher than expected for random dynamics.  ...  In this context, numerical simulations play an important role shedding light on basically involved mechanisms, such as the role of large breathers [5] , the Benjamin-Feir instability [6] , and the emergence  ...
