The latest version of our R library ghypernet is on CRAN. It allows studying multi-edge networks using generalised hypergeometric ensembles of random graphs. Install the package by running install.packages('ghypernet'), or go to ghyper.net for more info. #RStats
1/ Our new article is out — and made the cover of @ScienceMagazine.
“Supply-chain vulnerabilities in critical medicines”
📘 Science, 28 Aug 2025

4/ Resilience starts with transparency: without visibility into supply chains, governments can’t see vulnerabilities, prioritize action, or allocate resources effectively.

"Rather than expanding tariffs to pharmaceuticals, the US should build resilience in its medicine supply chains through targeted investments and international coordination," argue the authors of a new #LetterToScience.

ALT "Policy-makers and researchers must work together to foster a systemic understanding of pharmaceutical supply chain risks." - Casiraghi et al.
1/ Just published in @ScienceMagazine: our Letter on the risks of extending U.S. tariffs to pharmaceuticals.
Title: "US tariffs jeopardize medicine supply chains"
🔗 science.org/doi/10.1126/scie…
🧵👇
4/ We argue that the U.S. must avoid turning medicine into a trade weapon — and instead invest in resilience:
✅ Stockpile coordination
✅ Smart reshoring
✅ International cooperation
✅ Supply-chain visibility
5/ 📊 Our full, data-driven analysis is forthcoming.

1/ Traditional multi-edge network models yield dense networks, but empirical networks are sparse, with many node pairs remaining disconnected despite a high number of edges. 🧵
2/ This mismatch leads to significant inaccuracies in modeling complex systems like social interactions, disease spread, and information diffusion.
3/ Our study shows how zero-inflating multi-edge models significantly improves their fit and accuracy, providing an improved framework for studying complex systems. #NetworkScience #DataScience #ComplexSystems @ETH_en @ETH

Der Mangel an Arzneimitteln ist eine große Herausforderung für die Gesundheitssysteme in aller Welt. In der Schweiz zum Beispiel sind fast 1.000 krankenversicherte Medikamente nicht verfügbar. 📦 #Navigationssysteme #Medikamentenversorgung #Echtzeitmessung brnw.ch/21wGbBC
1/🧵Excited for our publication in @ScienceAdvances on the #resilience of pharma #SupplyChain. We introduce a framework to assess the potential of supply chains to adapt to disruptions.

4/Our method could integrate with existing pharmaceutial track and trace systems like #EMVS, enhancing its usefulness for policymaking. This framework also offers monitoring capabilities for other supply chains with complex distribution networks. @emvo_official
