244. An efficient local method for community detection in large networks
This is a guest blog post by Symeon Papadopoulos (MKLab, Informatics and Telematics Institute, Greece) who is going to determine whether effective community exist in the complex network of NEQNET readers Dmitry. I have been kindly given the opportunity by Dmitry to provide an overview of the problem of community detection in networks and discuss [...]
243. Turbulence: brief introduction into phenomenon
About a week ago I have listed top ten open problems in physics. If you say A, you are naturally supposed to say B (especially, if readers ask you ), so, I guess, I will have to discuss each problem from the list in more details. I would like to start with the problem N3 [...]

According to our tradition, no science discussions are allowed on Sunday (a gentleman has to be able to find fun beyond the area of his expertise), except maybe video of the day. So, I decided to revive the old topic – global financial crisis – and continue the discussion from where we stopped last time. [...]
