Now out: "Directionality-induced jamming in multiplex networks" (arxiv.org/abs/2510.22634). We uncover a previously unreported diffusion regime, termed directionality-induced jamming, in multiplex networks that arises solely from the directionality of interlayer couplings. (1/4)

Advancing coupled behavioural-epidemic models: An interdisciplinary framework for the collection of empirical data
Infection control requires integrating behavioural dynamics into epidemic models. However, models often overlook behavioural complexity due to limited empirical data. We adopted an interdisciplinary a...
