Oscillations and collective behavior in convection-driven fluid columns are investigated discussed analogy with similar phenomenon observed for the flickering flames of candle bundles. Experimentally, it is shown that an ascending circular helium gas column performs oscillation which several aspects to diffusion flames. Increasing nozzle diameter leads a decrease frequency, while increasing flo...

We calculate a measure of statistical complexity from the global dynamics of electroencephalographic (EEG) signals from healthy subjects and epileptic patients, and are able to stablish a criterion to characterize the collective behavior in both groups of individuals. It is found that the collective dynamics of EEG signals possess relative higher values of complexity for healthy subjects in com...

According to experts, the inefficient agricultural sector has a dominant role in degrading water resources all over the world. Farmers’ conservational behavior is an important aspect of new integrated water management studies. Relevantly, various behavioral theories have been proposed in the field of environmental psychology. The main objective of the present comparative analysis and review stu...

Human collective behavior can vary from calm to panicked depending on social context. Using videos publicly available online, we study the highly energized collective motion of attendees at heavy metal concerts. We find these extreme social gatherings generate similarly extreme behaviors: a disordered gas-like state called a mosh pit and an ordered vortex-like state called a circle pit. Both ph...

Most eukaryotic cells sense and respond to the mechanical properties of their surroundings. This can strongly influence their collective behavior in embryonic development, tissue function, and wound healing. We use a deformable substrate to measure collective behavior in cell motion due to substrate mediated cell-cell interactions. We quantify spatial and temporal correlations in migration velo...
