Fully nonlinear dynamics of stochastic thin-film dewetting

S. Nesic, R. Cuerno, E. Moro, and L. Kondic Physical Review E 92, 061002(R) [LINK] [PDF] Summary: The spontaneous formation of droplets via dewetting of a thin fluid film from a solid substrate allows materials nanostructuring. Often, it is crucial to be able to control the evolution, and to produce patterns characterized by regularly spaced droplets. While thermal fluctuations are expected to...

Affinity Paths and information diffusion in social networks

José Luis Iribarren and Esteban Moro Social Networks 33, 134-142 (2011)  [pdf] Abstract Widespread interest in the diffusion of information through social networks has produced a large number of Social Dynamics models. A majority of them use theoretical hypothesis to explain their diffusion mechanisms while the few empirically based ones average out their measures over many messages of different contents....

The speed and reach of forwarded emails, rumors, and hoaxes in electronic social networks

The speed and reach of forwarded emails, rumors, and hoaxes in electronic social networks

We have just published an experimental/theoretical work on the speed of information diffusion in social networks in Physical Review Letters. Specifically we have studied the impact of the heterogeneity of human activity in propagation of emails, rumors, hoaxes, etc. Tracking email marketing campaigns, executed by IBM Corporation in 11 European countries, we were able to compare their viral propagation with our...

We’ve heard it: people that invest on the stock market or that gamble in lotteries, casinos, etc usually say “I’m going through a bad patch” (or bad spell). That is, they have been losing money for a while, but hey! better times are ahead and there’s no reason to quit. Are they sure? Are better times ahead? How close is...

But sometimes my car decides I should take public transportation (bus or train). One of things I always found intriguing is that I always wait way more for the bus than what is expected according to the frequency...
