In recent years, social media has become an important platform for political discourse, being a site of both conversations between voters and advertisements from campaigns. While their individual influences on public discourse are well documented, the interplay individual-level cognitive biases, influence processes, dueling campaign efforts, platforms remains unexamined. We introduce agent-based model that integrates these dynamics illustrates how combination can lead to formation echo...

Information spreading in online social communities has attracted tremendous attention due to its utmost practical values applications. Despite that several individual-level diffusion data have been investigated, we still lack the detailed understanding of pattern information. Here, by comparing information flows and links a blog community, find processes are induced three different mechanisms: spreading, self-promotion broadcast. Although numerous previous studies employed epidemic models...

While the link between brain structure and function remains an ongoing challenge, prevailing hypothesis is that structure-function relationship may itself be gradually decoupling from unimodal to transmodal cortex. However, this constrained by underlying models which neglect requisite information. Here we relate structural functional connectivity derived diffusion MRI through orthogonal eigenmodes governing frequency-specific patterns. We find low-frequency contribute little interactions in...

Environmental changes play a critical role in determining the evolution of social dilemmas many natural or systems. Generally, environmental include two prominent aspects: global time-dependent fluctuations and local strategy-dependent feedbacks. However, impacts these types have only been studied separately, complete picture effects exerted by combination aspects remains unclear. Here we develop theoretical framework that integrates group strategic behaviors with their general dynamic...

The information diffusion process in single complex networks has been extensively studied, especially for modeling the spreading activities online social networks. However, individuals usually use multiple at same time, and can share they have learned from one network to another. This phenomenon gives rise a new on multiplex with more than layer. In this paper we account by proposing model of two-layer We develop theoretical framework using bond percolation cascading failure describe...

We investigate the collective dynamics of excitatory-inhibitory excitable networks in response to external stimuli. How enhance dynamic range, which represents ability encode stimuli, is crucial many applications. regard system as a two-layer network (E layer and I layer) explore criticality range on diverse networks. Interestingly, we find that phase transition occurs when dominant eigenvalue E layer's weighted adjacency matrix exactly 1, only determined by topology layer. Meanwhile, it...

Abstract A good group reputation often facilitates more efficient synergistic teamwork in production activities. Here we translate this simple motivation into a reputation-based synergy and discounting mechanism the public goods game. Specifically, type of group, either or bad determined by threshold, modifies nonlinear payoff structure described unified impact factor. Results show that incentive could effectively promote cooperation compared with linear payoffs, despite coexistence effects....

To date, most studies on autism spectrum disorder (ASD) have focused specific age ranges, while the mechanisms underlying entire developmental process of patients remain unclear. The aim this study was to investigate alterations in brain function autistic individuals at different stages by resting-state functional MRI (rs-fMRI). We obtained rs-fMRI data from 173 ASD and 178 typical development (TD) Autism Brain Imaging Data Exchange, spanning child, adolescent, adult groups. characterized...

Age-related hearing loss (ARHL) is a common sensory disability among older adults and considered risk factor for the development of dementia. Previous work has shown altered brain connectome topology in ARHL, including abnormal nodal strength clustering coefficient. However, whether ARHL affects hierarchical organization structural how these alterations relate to transcriptomic signatures remain unknown. Here, we apply gradient mapping framework derived from diffusion magnetic resonance...

Indirect reciprocity unveils how social cooperation is founded upon moral systems. Within the frame of dyadic games based on individual reputations, ‘leading-eight’ strategies distinguish themselves in promoting and sustaining cooperation. However, real-world societies, there are widespread interactions at group level, where individuals need to make a singular action choice when facing multiple with different reputations. Here, through introducing assessment collective we develop framework...

Cocaine use disorder (CUD) is a chronic brain condition that severely impairs cognitive function and behavioral control. The neural mechanisms underlying CUD, particularly its impact on integration-segregation dynamics, remain unclear. In this study, we integrate dynamic functional connectivity graph theory to compare the state properties of healthy controls CUD patients. We find influences both integrated segregated states, leading distinct alterations in patterns network properties....

Immunization plays an important role in the field of epidemic spreading complex networks. In previous studies, targeted immunization has been proved to be effective strategy. However, when extended networks with community structure, it is unknown whether superior strategy vaccinate nodes who have most connections entire network (global strategy), or those original where starts spread (local strategy). this work, by using both analytic approaches and simulations, we observe that answer...
