The Unreasonable Effectiveness of Contact Tracing on Networks with Cliques 🔗 arxiv.org/abs/2304.10405 Contact tracing, the practice of isolating individuals who have been in contact with infected individuals, is an effective and practical way of containing disease spread. Here, we show that this strategy is particularly effective in the presence of social groups: Once the disease enters a group, contact tracing not only cuts direct infection paths but can also pre-emptively quarantine group members such that it will cut indirect spreading routes. We show these results by using a deliberately stylized model that allows us to isolate the effect of contact tracing within the clique structure of the network where the contagion is spreading. This will enable us to derive mean-field approximations and epidemic thresholds to demonstrate the efficiency of contact tracing in social networks with small groups. This analysis shows that contact tracing in networks with groups is more efficient the larger the groups are. We show how these results can be understood by approximating the combination of disease spreading and contact tracing with a complex contagion process where every failed infection attempt will lead to a lower infection probability in the next attempts. Our results illustrate how contract tracing in real-world settings can be more efficient than predicted by models that treat the system as fully mixed or the network structure as locally tree-like. 🧵Check out this thread: https://threadreaderapp.com/thread/1649344692771778560.html

Unifying Pairwise Interactions in Complex Dynamics Oliver M. Cliff, Joseph T. Lizier, Naotsugu Tsuchiya, Ben D. Fulcher arxiv.org/abs/2201.11941 Scientists have developed hundreds of techniques to measure the interactions between pairs of processes in complex systems. But these computational methods -- from correlation coefficients to causal inference -- rely on distinct quantitative theories that remain largely disconnected. Here we introduce a library of 249 statistics for pairwise interactions and assess their behavior on 1053 multivariate time series from a wide range of real-world and model-generated systems. Our analysis highlights new commonalities between different mathematical formulations, providing a unified picture of a rich, interdisciplinary literature. We then show that leveraging many methods from across science can uncover those most suitable for addressing a given problem, yielding high accuracy and interpretable understanding. Our framework is provided in extendable open software, enabling comprehensive data-driven analysis by integrating decades of methodological advances.
