Rain initiation time in turbulent warm clouds
G. Falkovich, M. G. Stepanov, M. Vucelja
We present a mean-field model that describes droplet growth due to condensation and collisions and droplet loss due to fallout. The model allows for an effective numerical simulati…

Growth of density inhomogeneities in a flow of wave turbulence
A. M. Balk. G. Falkovich, M. S. Stepanov
We consider an advection of a passive scalar by a flow which is a superposition of random waves. We find that such a flow can lead to an exponential growth of the passive scalar fl…

Resampling methods for document clustering
D. Volk, M. G. Stepanov
We compare the performance of different clustering algorithms applied to the task of unsupervised text categorization. We consider agglomerative clustering algorithms, principal di…
