Teleconnections and relationship between the El Niño–Southern Oscillation (ENSO) and the Southern Annular Mode (SAM) in reconstructions and models over the past millennium

Dätwyler, Christoph ; Grosjean, Martin ; Steiger, Nathan J. ; Neukom, Raphael

In: Climate of the Past, 2020, vol. 16, no. 2, p. 743–756

The climate of the Southern Hemisphere (SH) is strongly influenced by variations in the El Niño–Southern Oscillation (ENSO) and the Southern Annular Mode (SAM). Because of the limited length of instrumental records in most parts of the SH, very little is known about the relationship between these two key modes of variability over time. Using proxy-based reconstructions and last-millennium...

Influencers identification in complex networks through reaction-diffusion dynamics

Iannelli, Flavio ; Mariani, Manuel S. ; Sokolov, Igor M.

In: Physical Review E, 2018, vol. 98, no. 6, p. 062302

A pivotal idea in network science, marketing research, and innovation diffusion theories is that a small group of nodes—called influencers—have the largest impact on social contagion and epidemic processes in networks. Despite the long-standing interest in the influencers identification problem in socioeconomic and biological networks, there is not yet agreement on which is the best...
