Addressing wealth and income inequality requires a thorough understanding of the mechanisms driving these disparities. Agent-Based Models (ABMs) offer a powerful tool for simulating these complex systems, capturing the intricate interplay of individual behaviors and emergent macroeconomic trends.

The authors introduce a rejection-based stochastic sampling algorithm with high acceptance probability (‘high-acceptance sampling’; HAS), tailored to simulate disease spreading on adaptive networks. They demonstrate that HAS is exact and can be multiple orders faster than Gillespie’s algorithm.

The authors study a system of collectively migrating cells with attracting (adhesive) interactions and heavy-tailed distributed jump lengths. To this end, they developed a multi-speed lattice-gas cellular automaton model, and analyzed it both computationally and analytically.

The authors assess the structural complexity underlying the spatial configuration of urban state variables in Medellín. Leveraging the concept of the urban fractal, they describe the general organizational mode of the urban plane in terms of movement and mobility, while employing fractal dimension to quantify the dynamic affinities among different urban state variables.

There is a lack of approaches to characterize the functional properties of such biological neuronal networks without resorting to dimensionality reduction methods. The authors introduce an approach to describe these functional properties by using its activity-defining constituents, the weights of the synaptic connections and the current activity of its neurons.

Here, we investigate the relationship between obesity and impulsivity through urban scaling and causal discovery. For 915 cities in the United States of America, we study the prevalence of obesity in adults, attention deficit hyperactivity disorder (ADHD) in children, and relevant urban features.

The concept of centrality is one of the essential tools for analyzing complex systems. Over the years, a large number of centrality indices have been proposed that account for different aspects of a network. Unfortunately, most real networks are substantially incomplete, which affects the results of the centrality measures.
