Network connectivity analysis via shortest paths https://arxiv.org/abs/2509.03230

Strikingly, the shortest-path percolation homogenizes scale-free networks before the phase transition, resulting in the same universality class as the Erdős–Rényi Networks! Check out our new preprint on arXiv: arxiv.org/abs/2509.09142

Q: How are resources consumed in transportation networks, and how does this shape the overall functioning of the system? We introduce the minimum-cost percolation framework and apply it to the U.S. air transportation system using publicly available data. 🔗 www.nature.com/articles/s41...

Happy to share this long-overdue project! We found that many real-world event sequences follow a surprisingly similar hierarchically structured pattern, and that multi-timescale memory mechanisms can explain this pattern. Feedback welcome! arxiv.org/abs/2508.18281

New Pre-print out 📝 We propose a minimum-cost percolation (MCP) framework to model resource consumption in transportation networks, applied to the US air system. Encouraging cooperation among air carriers can boost the system’s robustness to disruptions! arXiv: arxiv.org/abs/2504.04245
