Bimodularity introduces a new approach to network analysis by detecting directionality, enabling identification of both sender and receiver communities in complex directed systems. doi.org/g9zgxb
Breaking the code in network theory: Bimodularity reveals direction of influence in complex systems
As summer winds down, many of us in continental Europe are heading back north. The long return journeys from the beaches of southern France, Spain, and Italy once again clog alpine tunnels and Mediterranean coastal routes during the infamous Black Saturday bottlenecks.
