Summary: The study highlights the differences between complex contagions and simple contagions, showing that exposure to multiple peers may be necessary for adoption in complex contagions. Traditional measures of path length fail to accurately define network connectedness and node centrality for complex contagions. To address this issue, researchers have developed new measures of complex path length and complex centrality.

Summary: The study shows that incorporating differences in vulnerability to predation and foraging efficiency between juvenile and adult individuals can result in larger and more complex communities in model simulations. These diverse communities are stable or fluctuate with limited amplitude, even with a highly connected population-level interaction network. This suggests that differences between juveniles and adults may have a significant impact on the stability of natural communities.

Summary: This paper proposes a competing spread model for two epidemics on higher-order networks and analyzesthe factors that affect the spread process. The experimental results show that the difference in 1-simplex infection rates between the two epidemics and the increase in 2-simplex infection rates have significant impacts on the spread process.

Summary: Researchers propose a quantity called "entropy of temporal entanglement" to measure the topological complexities of temporal networks in a diverse set of real-world complex systems. Through simulations of different stochastic dynamics, they demonstrate that this entropy measure can quantitatively represent a system's spreading vulnerability, regardless of the process details. This measure has broad applications in natural, social, biological, and engineered systems.

Summary: This study proposes a methodological framework for analyzing and interpreting various topological descriptors in scenarios where network connectivity existence is statistically inferred or edge existence probabilities are known. The framework is based on numerical experiments performed on a large set of synthetic and real-world networks. By replacing topological descriptors with probability distributions, the reconstruction phase can be avoided.

Summary: This study demonstrates that the relationship between the number of species and interactions in a network can be defined by a single parameter, which is network-specific and relates to local stability and robustness. The trade-off between local stability and robustness is more prominent in mutualistic networks compared to trophic networks.

Summary: This study reports the induction of superconductivity by high pressure in three thallium-based materials and investigates the phase transition process between them. Density functional theory calculations reveal the existence of topological surface states in the superconductivity phases of all three materials. This research is of significance for exploring topological superconductivity and topological phase transitions.

Summary: The research introduces a community structure enhancement method, CSE, which enhances the community structure of a network by adding links between nodes possibly belonging to the same community and reducing links between those belonging to different communities, thereby making the ambiguous community structure clearer. The experimental results demonstrate the superior performance of CSE over five state-of-the-art community detection algorithms on both synthetic benchmark networks and real-world networks, especially for those without a clear community structure.

Summary: We use neutron scattering to investigate the spin dynamics and structures of Co3Sn2-xInxS2 as a function of x, and provide a microscopic understanding of the interplay between the anomalous Hall effect (AHE) and magnetism. Our results show that the spin gap and stiffness contribute to the AHE from Weyl fermions. The magnetic structure evolves from c-axis ferromagnetism to a canted antiferromagnetic structure with reduced c-axis moment and in-plane antiferromagnetic order as x increases. Furthermore, our findings reveal another contribution to the AHE from the noncollinear spins-induced Berry curvature, highlighting the importance of magnetism on transport.

Summary: The study investigates cascading dynamics in double-layer networks, identifying three types of percolation transitions and developing a theoretical framework to predict transition points. Validation on an empirical network shows that the model results align with observations of cascading failures in critical infrastructure systems. The research provides insights on designing double-layer networks for optimal resilience.

Summary: This paper examines the Chinese A-share stock prices in the context of the 2008 financial crisis, using a complex network perspective. The study explores possible cautionary phenomena and provides guidance for crisis identification and control. The results show that the size of time windows has an influence on the evolution of stock prices, and network parameters exhibit specific characteristics around the crisis.

Summary: This study calculates the molecular net complexity (H-molNet) for a set of molecular crystal structures and investigates the relationship between molecular coordination number and crystal structure complexity. The results show that most structures have a molecular coordination number of 14, and the average multiplicity of intermolecular contacts significantly decreases when excluding contacts not bearing the molecular net. The contribution of H-mol to H-molNet is large, and the subset of bearing intermolecular contacts accounts for a portion of the overall complexity of intermolecular contacts.
