Scientific productivity and collaboration are closely related, yet the causal direction between these two dimensions of academic careers remains unclear. Here we analyze the career…
Porosity and Material Disorder Drive Distinct Channelization Transition
André F. V. Matias, Rodrigo C. V. Coelho, Humberto A. Carmona +2
Flow through porous media can reshape the medium through erosion and deposition, producing preferential flow channels across a wide range of natural and industrial systems. Yet the…
Glassy phase transition in immiscible steady-state two-phase flow in porous media
