Boundary Degree as a Node-level Feature for Epidemic Scenario Identification in Agent-based Cascade Simulations
Amro Alabsi Aljundi, Galen Harrison, Jiangzhuo Chen +3
Characterizing the scenario underlying an epidemic from its disease cascade is an important task in simulation analytics. We propose boundary degree, the count of an infected node'…
Robust Network Flow Interdiction Problems with Applications to Counter-Narcotics
Diksha Gupta, Madhav Marathe, Anil Vullikanti
Interdiction problems arise in a number of application areas, including global security, supply chains, and critical infrastructure protection - the goal is inhibit the movement of…
Cascading Impacts of the USA--China Trade War on Global Oilseed Supply Chain
Diksha Gupta, Ritwick Mishra, Achla Marathe +2
Global supply chains are highly interconnected, making them vulnerable to cascading disruptions induced by trade policy shocks. Understanding how such disruptions propagate through…
Scalable K-clique Estimation with Differential Privacy
Dung Nguyen, Ritwick Mishra, Anil Vullikanti
Counts of -cliques are commonly used metrics in subgraph mining. Since graphs often have sensitive data, there also has been a lot of work on -clique counts with differential…
Estimating the cascading global impacts of gas disruptions in Qatar
Ritwick Mishra, Diksha Gupta, Achla Marathe +7
This study examines the global impacts of a localized disruption in Qatar's gas sector using a multi-regional input-output framework and scenario-based analysis. While the direct i…
