Summary: Combinatorial threshold-linear networks (CTLNs) are a special class of TLNs defined from directed graphs. In this study, a type of fixed points called core motifs are found to predict both static and dynamic attractors in CTLNs. By choosing initial conditions that are small perturbations of these fixed points, attractors can be found. Furthermore, it is discovered that core motifs with similar embeddings give rise to nearly identical attractors. This study suggests that graphical properties of connectivity can be used to predict a network's complex repertoire of nonlinear dynamics.

Summary: This article proposes a socio-technical network perspective to study the complex relationships among social actors and technical elements in infrastructure systems. By analyzing network concepts and socio-technical motifs, a deeper understanding of digitalization, decentralization, and integrated management in infrastructure systems can be achieved.

Summary: Complex Networks theory is a powerful tool to model real-world systems with nontrivial topological features. Research shows that networks preserve dynamic flow between structures at different scales. Although the principle of convergence is widely agreed upon, the transition from micro to macro has not been studied enough, emphasizing the importance of an in-between layer.

Summary: This paper proposed a dynamic cascade model to study the systemic risk posed by sector-level industries within the U.S. inter-industry network and investigated the effect of Covid-19 disruptions on the U.S. economy. By simulating the propagation of production shortages due to initial shocks, a critical resilience value in the network was observed, below which a catastrophic collapse occurred.

Summary: This study examines the contemporary and dynamic effects of socio-economic factors on individuals' decisions to allocate their time to physical activities, particularly focusing on the intensity of these activities. The results show that changes in the opportunity cost of time significantly impact individuals' decisions, while income has a smaller effect. Additionally, employed individuals engage in more physical activity than inactive individuals, and higher education levels increase the probability of participation but decrease the time spent in physical activities. There are also gender differences in the impact of household production on physical activity consumption.

Summary: Psychological frameworks are rarely used to understand irrigation adoption behavior in developing countries. This study developed a Bayesian belief network model that integrated socio-economic characteristics and psychological factors to understand farmer behaviors with respect to irrigation practices in four districts of Maharashtra, India.

Summary: By introducing metal-ligand interactions, the break strength and Young's modulus of self-healing materials have been significantly increased while maintaining high stretchability. These new materials exhibit excellent repairing capability, showing significant potential for future applications.

Summary: Networks with absolute concentration robustness exhibit stability in the concentration of one species regardless of the initial conditions and the concentrations of other species. By studying small reaction networks, we classified these networks based on their concentration robustness properties and observed rich dynamics even in this simple setting.

Summary: This study demonstrates the fine-tuned control over macroscopic dynamic material properties using the Hammett equation in tuneable dynamic covalent polyimine materials. By systematically varying the dynamic covalent bond dynamics through selection of appropriate substituents, the research shows a correlation between Hammett parameter and various dynamic material properties. The results showcase the direct tunability and design of dynamic material properties in a quantitative and predictable manner, with the potential for recycling and self-healing over multiple cycles.

Summary: Cells use molecular signaling networks to interpret stimuli, with single-cell variability influencing phenotypic responses. The hypothesis of a single signaling motif explaining cell-to-cell variability was tested using the algorithm MISC. Mechanistic information about cellular signaling networks can be extracted from single-cell dynamic patterns.

Summary: This study used dynamic microsimulation modelling to assess the implications of socio-economic disparities for healthcare costs from a cumulative life course perspective. The results showed that individuals with lower socio-economic status have lower healthcare costs compared to those with higher socio-economic status, after accounting for mortality differentials. Therefore, reducing social inequalities in health can help to contain healthcare expenditures.

Summary: In this study, a new index combining tie strength and spatial distance is proposed to measure the average spatial dispersion of socio-economic activities. The index is used to analyze the migration flow network between provinces of Turkey and to test the effects of population and economic development on spatial dispersion of migration.

Summary: Students of different socio-economic backgrounds are assigned to different schools, which affects the structure of networks within schools. This study examines the tendency for friendship and parental networks in primary schools to be structured by socio-economic status (SES), and explores the role of the local school context. Data from Dutch students in 68 classrooms were analyzed using exponential random graph models and meta-analysis techniques. The findings suggest that primary school networks tend to have same-SES ties, regardless of opportunity structures. There is no evidence for SES differences in the strength of SES homophily.

Summary: The revitalization of small towns is crucial for improving the quality of life of residents living in degraded areas and high-risk social exclusion areas. While unemployment rates have decreased in the studied cities, the impact of revitalization projects on reducing crime rates and increasing educational and professional involvement of residents from marginalized areas is limited. The results may inform strategies to address socioeconomic problems and provide recommendations for revitalizing small towns in Europe and around the world.
