Stability of heteroclinic cycles in rings of coupled oscillators
Posted on

Learning a weather dictionary of atmospheric patterns using Latent Dirichlet Allocation
Posted on
by
The mid-latitude atmospheric circulation is challenging to describe due to the turbulent and chaotic nature of the underlying flow, driven by the unstable dynamics of the jet stream. In general, the phase space of such turbulent geophysical flows appears to be large. […]

Metrics and Mechanisms: Measuring the Unmeasurable in the Science of Science
Posted on
by
How does science work? What are its core mechanisms? In recent decades, research has increasingly explored such questions using a variety of quantitative metrics which can be easily calculated from publications. But some of these can be deceiving.
