Emergence of heterogeneity and political organization in information exchange networks
Nicholas Guttenberg, Nigel Goldenfeld
We present a simple model of the emergence of the division of labor and the development of a system of resource subsidy from an agent-based model of directed resource production wi…
Macroscopic effects of the spectral structure in turbulent flows
Tuan Tran, Pinaki Chakraborty, Nicholas Guttenberg +5
Two aspects of turbulent flows have been the subject of extensive, split research efforts: macroscopic properties, such as the frictional drag experienced by a flow past a wall, an…
The turbulent mean-velocity profile: it is all in the spectrum
Gustavo Gioia, Nicholas Guttenberg, Nigel Goldenfeld +1
It has long been surmised that the mean-velocity profile (MVP) of a pipe flow is closely related to the spectrum of turbulent energy. Here we perform a spectral analysis to identif…
Extreme fluctuations and the finite lifetime of the turbulent state
Nigel Goldenfeld, Nicholas Guttenberg, Gustavo Gioia
We argue that the transition to turbulence is controlled by large amplitude events that follow extreme distribution theory. The theory suggests an explanation for recent observatio…
