    A Weibo local network growth model constructed from the perspective of following-followed

    查看更多>>摘要：In order to explore the evolution process of the Weibo local network,this study first defines four factors influencing the evolution of the Weibo network.On this basis,the BA scale-free network model was enhanced by incorporating these four factors and accounting for directionality,resulting in a Weibo local network evolution model based on user attributes and behavioral similarity.The model's validity was validated by comparing simulation results with real data.The findings indicate that the Weibo local network exhibits both small-world characteristics and distinctive features.The results show that the Weibo local network exhibits both small-world characteristics and distinctive properties.The in-degree distribution follows a mixed pattern of exponential and power-law distributions,the degree-degree shows isomatching,and both the in-degree centrality and eigenvector centrality values are relatively low.This research contributes to our understanding of user behaviour in the Weibo network,and provides a structural basis for exploring the impact of Weibo network structure on information dissemination.

    Effect of different injection strategies considering intravenous injection on combination therapy of magnetic hyperthermia and thermosensitive liposomes

    查看更多>>摘要：The combination therapy of magnetic hyperthermia and thermosensitive liposomes(TSL)is an emerging and effective cancer treatment method.The heat generation of magnetic nanoparticles(MNPs)due to an external alternating magnetic field can not only directly damage tumor cells,but also serves as a triggering factor for the release of doxorubicin from TSL.The aim of this study is to investigate the effects in the degree of tumor cell damage of two proposed injection strategies that consider intravenous administration.Since both MNPs and TSL enter the tumor region intravenously,this study establishes a biological geometric model based on an experiment-based vascular distribution.Furthermore,this study derives the flow velocity of interstitial fluid after coupling the pressure distribution inside blood vessels and the pressure distribution of interstitial fluid,which then provides the convective velocity for the calculation of subsequent nanoparticle concentration.Different injection strategies for the proposed approach are evaluated by drug delivery result,temperature distribution,and tumor cell damage.Simulation results demonstrate that the proposed delayed injection strategy after optimization can not only result in a wider distribution for MNPs and TSL due to the sufficient diffusion time,but also improves the distribution of the temperature and drug concentration fields for the overall efficacy of combination therapy.

    Simulation of crowd evacuation under attack considering emotion spreading

    576-588页
    查看更多>>摘要：In recent years,attacks against crowded places such as campuses and theaters have had a frequent and negative impact on the security and stability of society.In such an event,the crowd will be subjected to high psychological stress and their emotions will rapidly spread to others.This paper establishes the attack-escape evacuation simulation model(AEES-SFM),based on the social force model,to consider emotion spreading under attack.In this model,(1)the attack-escape driving force is considered for the interaction between an attacker and evacuees and(2)emotion spreading among the evacuees is considered to modify the value of the psychological force.To validate the simulation,several experiments were carried out at a university in China.Comparing the simulation and experimental results,it is found that the simulation results are similar to the experimental results when considering emotion spreading.Therefore,the AEES-SFM is proved to be effective.By comparing the results of the evacuation simulation without emotion spreading,the emotion spreading model reduces the evacuation time and the number of casualties by about 30％,which is closer to the real experimental results.The results are still applicable in the case of a 40-person evacuation.This paper provides theoretical support and practical guidance for campus response to violent attacks.

    Hyperbolic map unravels eight regions in temperature volatility regionalization of Mainland China

    宋雨轩顾长贵郑木华冯爱霞...
    589-598页
    查看更多>>摘要：Abrupt temperature volatility has detrimental effects on daily activities,macroeconomic growth,and human health.Predicting abrupt temperature volatility and thus diminishing its negative impacts can be achieved by exploring homoge-neous regions of temperature volatility and analyzing the driving factors.To investigate the regionalization of temperature volatility in Mainland China,a network constructed by the cosine similarity of temperature volatility series from Mainland China was embedded in hyperbolic space.Subsequently,we partitioned the network on the hyperbolic map using the critical gap method and then found eight regions in all.Ultimately,a network of communities was constructed while the interaction among communities was quantified.This yields a perspective of temperature volatility regionalization that can accurately reflect factors including altitude,climate type,and the geographic location of mountains.Further analysis demonstrates that the regionalization in the hyperbolic map is distinct from provinces and has a realistic basis:communities in southwest China show strong correlations due to the temperature sensitivity to altitude,and communities in northern China show a convergence in the area of Dingxi,Gansu,mainly owing to the strong temperature sensitivity to climate types.As a conse-quence,node distributions and community divisions in the hyperbolic map can offer new insights into the regionalization of temperature volatility in Mainland China.The results demonstrate the potential of hyperbolic embedding of complex networks in forecasting future node associations in real-world data.

    Impact of environmental factors on the coevolution of information-emotions-epidemic dynamics in activity-driven multiplex networks

    599-615页
    查看更多>>摘要：During public health emergencies,the diffusion of negative information can exacerbate the transmission of adverse emotions,such as fear and anxiety.These emotions can adversely affect immune function and,consequently,influence the spread of the epidemic.In this study,we established a coupled model incorporating environmental factors to explore the coevolution dynamic process of information-emotions-epidemic dynamics in activity-driven multiplex networks.In this model,environmental factors refer to the external conditions or pressures that affect the spread of information,emotions,and epidemics.These factors include media coverage,public opinion,and the prevalence of diseases in the neighborhood.These layers are dynamically cross-coupled,where the environmental factors in the information layer are influenced by the emotional layer;the higher the levels of anxious states among neighboring individuals,the greater the likelihood of information diffusion.Although environmental factors in the emotional layer are influenced by both the information and epidemic layers,they come from the factors of global information and the proportion of local infections among surrounding neighbors.Subsequently,we utilized the microscopic Markov chain approach to describe the dynamic processes,thereby obtaining the epidemic threshold.Finally,conclusions are drawn through numerical modeling and analysis.The conclu-sions suggest that when negative information increases,the probability of the transmission of anxious states across the population increases.The transmission of anxious states increases the final size of the disease and decreases its outbreak threshold.Reducing the impact of environmental factors at both the informational and emotional levels is beneficial for con-trolling the scale of the spread of the epidemic.Our findings can provide a reference for improving public health awareness and behavioral decision-making,mitigating the adverse impacts of anxious states,and ultimately controlling the spread of epidemics.
