Foundations of Computational Mathematics, 2021 This paper is concerned with the derivation and properties of differential complexes arising from a variety of problems in differential equations, with applications in continuum mechanics, relativity, and other fields. We present a systematic procedure which, starting from well-understood differential complexes such as the de Rham complex, derives new ...

A large-scale empirical investigation of specialization in criminal career
Scientific Reports, 2023 We use a comprehensive longitudinal dataset on criminal acts over 6 years in a European country to study specialization in criminal careers. We present a method to cluster crime categories by their relative co-occurrence within criminal careers, deriving

Inequality and inequity in network-based ranking and recommendation algorithms
Scientific Reports, 2022 Though algorithms promise many benefits including efficiency, objectivity and accuracy, they may also introduce or amplify biases. Here we study two well-known algorithms, namely PageRank and Who-to-Follow (WTF), and show to what extent their ranks ...

Quantifying firm-level economic systemic risk from nation-wide supply networks
Scientific Reports, 2022 Crises like COVID-19 exposed the fragility of highly interdependent corporate supply networks and the complex production processes depending on them. However, a quantitative assessment of individual companies’ impact on the networks’ overall production ...

Stress-testing the resilience of the Austrian healthcare system using agent-based simulation
Nature Communications, 2022 As mass quarantines, absences due to sickness, or other shocks thin out patient-physician networks, the system might be pushed to a tipping point where it loses its ability to deliver care.

The complexity of cutting complexes [PDF]
Discrete & Computational Geometry, 1989 This paper investigates the combinatorial and computational aspects of certain extremal geometric problems in two and three dimensions. Specifically, we examine the problem of intersecting a convex subdivision with a line in order to maximize the number of intersections.

Studying Complexity is Complex [PDF]
Journal of General Internal Medicine, 2007 This supplement contains 9 articles that arose from a Department of Veterans Affairs sponsored State of the Art (SOTA) conference “Managing Complexity in Chronic Care.” It is appropriate that these articles appear in the Journal of General Internal Medicine.

On the Complexity of Automatic Complexity [PDF]
Theory of Computing Systems, 2017 Generalizing the notion of automatic complexity of individual strings due to Shallit and Wang, we define the automatic complexity $A(E)$ of an equivalence relation $E$ on a finite set $S$ of strings. We prove that the problem of determining whether $A(E)$ equals the number $|E|$ of equivalence classes of $E$ is $\mathsf{NP}$-complete.

Simplicial Complexes are Game Complexes [PDF]
The Electronic Journal of Combinatorics, 2019 Strong placement games (SP-games) are a class of combinatorial games whose structure allows one to describe the game via simplicial complexes. A natural question is whether well-known parameters of combinatorial games, such as "game value", appear as invariants of the simplicial complexes. This paper is the first step in that direction.
