Failure of a critical node partitions the network into two or more disjoint segments and may disrupt the network operation.
In fact, the connectivity and coverage of the network can be greatly affected if the failure involves a critical node during the repair time of nodes.
The remaining 11 papers present new research on critical node detection, diversity graphs, the complexity of feature selection, subjective and objective pharmacovigilance association measures, EEG recordings of mesial temporal lobe epilepsy, and projected clustering.

A network's vulnerability to disruption lies in what netwar expert Phil Williams calls critical nodes. A critical node is a person or cell whose function has a "high level of importance and a low level of redundancy." (41) This could mean a person with an important but rare skill.
For some city pairs, disruptions in nearly a dozen specific nodes would not make much difference in Internet reliability, but a disruption in a single critical node would cause major problems--and such critical nodes may be different for any particular pair of cities.
Air Force and America's air and space power hinges, I believe, on one critical node and that's our people.
Similar approach involves, for example, immunization of disease carriers [24, 25] or critical node detection [26-28], where the sequence of deletion order is not taken into account, and only the optimum subset of nodes selected for deletion is important.
