A Splitting Architecture for Exact Reduced Coulomb Friction

Computer Graphics Forum, EarlyView.
Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

A spectral analysis extension to DEMATEL for strategic leverage points identification

International Transactions in Operational Research, EarlyView.
Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...

The impact of alignment and scaling on biological inferences from landmark‐free morphometrics

Journal of Anatomy, EarlyView.
Landmark‐free morphometrics promises advancements in shape quantification for biology, but widespread adoption is hampered by concerns over reproducibility. We compare 3D mesh alignment and scaling protocols on a prominent landmark‐free approach, Deterministic Atlas Analysis, finding inconsistencies in centroid size distribution and variance structure.

A Unified Approach to Estimating Production Functions: Proxy Variables and Dynamic Panel Data

The Journal of Industrial Economics, EarlyView.
ABSTRACT We propose a new approach to production function estimation that integrates the strengths of the proxy‐variable (PV) and dynamic panel data (DPD) methods. Our framework augments the set of instruments for the level equation in Blundell and Bond [8] with a Berkson‐type instrument motivated by economic theory, following Olley and Pakes [28 ...

Organized Crime, Corruption, and Economic Growth

Journal of Regional Science, Volume 65, Issue 2, Page 535-560, March 2025.
ABSTRACT In this paper, we study the relationship between organized crime, corruption, and economic growth on a data set from Italian regions for the period 1996–2013. Our working hypothesis is that organized crime can embezzle part of the public expenditure aimed at productive uses by threatening and bribing public officers. To assess the consequences
