Spatial dynamics can promote persistence of strongly interacting predators and prey. Theory predicts that spatial predator–prey systems are prone to long transients, meaning that the dynamics leading to persistence or extinction manifest over hundreds of generations. Furthermore, the form and duration of transients may be altered by spatial network structure. Few empirical studies have examined...
Substance use poses a significant threat to the health of women, and homeless women are more likely to use alcohol and drugs than other women. Addressing risk factors in this population requires a focus on the social context of substance use among homeless women.Participants were 445 homeless women who were randomly sampled and interviewed in shelter settings about the characteristics of their personal...
At present, the realities of acoustic communications and undersea networks differ substantially from the expectations arising from academic theory and investigation. The issue is not that the fundamentals of communications theory do not apply, but rather the fact that the difficulties of the acoustic channel do not necessarily fit the assumptions underlying conventional applications of that theory...
Modular structure is the most common way of managing complexity in large systems, but how modules emerge in self-organizing systems is poorly understood. Here we show that in complex networks, modules can form spontaneously under dual phase evolution (DPE), a process in which a system repeatedly flips between a weakly connected ldquobalancerdquo phase and a richly connected ldquovariationrdquo phase...
