“The synthetic images accurately reproduced the vortexes’ appearance and dynamics, including growth rate, distribution, and propagation speeds, which led the team to conclude their observations are most likely real.”
“By combining material flow analysis with a multilayer shock propagation model, researchers found that risks often originate in upstream parts of the supply chain but become most severe at key refining and manufacturing bottlenecks.”
