Improving Affordability and Accessibility for Socially‐Beneficial Services via Government Incentives
Naval Research Logistics (NRL), EarlyView.ABSTRACT Many socially‐beneficial services, like dental care, suffer from a dual challenge: Low affordability for citizens and long waiting times due to insufficient provider capacity. We model a government's problem of designing subsidy policies to address this issue.

Environmental Footprint of Diffuse Emissions in European Functional Urban Areas
Sustainable Development, EarlyView.ABSTRACT This paper quantifies the environmental footprint of diffuse air emissions across 776 European functional urban areas (FUAs) from 2005 to 2022 by coupling Copernicus Atmosphere Monitoring Service (CAMS) gridded inventories with the Environmental Footprint (EF) 3.1 framework.

Note on structural properties of graphs
Open Mathematics, 2022 In this paper, we establish sufficient and necessary conditions for the existence of abelian subgroups of maximal order of a finite group GG, by means of its commuting graph.

Sustainable Development, EarlyView.ABSTRACT This study investigates how citizens' mobility preferences align with the principles of the 15‐Minute City (15mC), addressing three research questions: what access times and transport modes citizens consider acceptable, whether mobility preference can be clustered, and which services are perceived incompatible with the 15mC.

Relative g-noncommuting graph of finite groups
Electronic Journal of Graph Theory and Applications, 2022 Let G be a finite group. For a fixed element g in G and a given subgroup H of G, the relative g-noncommuting graph of G is a simple undirected graph whose vertex set is G and two vertices x and y are adjacent if x ∈ H or y ∈ H and [x, y]≠g, g−1.

Perfect commuting graphs [PDF]
Journal of Group Theory, 2016 Abstract We classify the finite quasisimple groups whose commuting graph is perfect and we give a general structure theorem for finite groups whose commuting graph is perfect.

Local labor market frictions and platform‐based entrepreneurship
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Building on prior research about the heterogeneous impact of labor shocks on individuals' propensity to start businesses, we explore how local labor market frictions affect individuals' selection into platform‐based entrepreneurship.

GAGNN: a geography-aware graph neural network for citywide commuting flows prediction
International Journal of Applied Earth Observations and GeoinformationUrban commuting flow prediction is crucial for optimizing public transportation and improving efficiency, yet traditional models often focus on geographic adjacency, overlooking the complex cross-regional interactions within transportation networks.

A novel method to construct NSSD molecular graphs
Open Mathematics, 2019 A graph is said to be NSSD (=non-singular with a singular deck) if it has no eigenvalue equal to zero, whereas all its vertex-deleted subgraphs have eigenvalues equal to zero.
