Growth of critical fluctuations prior to catastrophic state transition is generally regarded as a universal phenomenon, providing a valuable early warning signal in dynamical systems. Using an ecological fisheries model of three populations (juvenile prey J, adult prey A and predator P), a recent study has reported silent early warning signals obtained from P and A populations prior to saddle-n...

Earthquake early warning (EEW) can reduce harm to people and infrastructure from earthquakes and tsunamis, but it has not been implemented in most high earthquake-risk regions because of prohibitive cost. Common consumer devices such as smartphones contain low-cost versions of the sensors used in EEW. Although less accurate than scientific-grade instruments, these sensors are globally ubiquitou...

Neural interactions between contralateral motor regions are thought to be instrumental in the successful preparation, and execution, of volitional movements. Here we investigated whether healthy ageing is associated with a change in functional connectivity, as indicated by the ability to modulate interhemispheric interactions during movement preparation in a manner that assists rapid movement r...

Warning signs have been widely applied to industrial production. As an important component of warning signs, warning signal words were mostly studied by using questionnaire. This study used event-related potentials (ERPs) to explore neural temporal features during the processing of warning signal words in human brain, and found that there were two stages involved in processing warning signal wo...

The increasing adoption of product recommendation agents (PRAs) by e-commerce merchants makes it an important area of study for Information Systems researchers. PRAs are a type of web personalization technology that provides individual consumers with product recommendations based on their productrelated needs and preferences expressed explicitly or implicitly. While extant research mainly assum...

the frequent occurrence of currency crises in recent years brought the early warning literature back in the researchers spotlight. in recent years, concept of an early warning system (ews) developed that should be able to identify various costly events, such as currency crises, early enough for policy makers to reduce the costs. this study attempted by using iran's economy quarterly data d...
