The Finding and Dynamic Detection of Opinion Leaders in Social Network [PDF]

Mathematical Problems in Engineering, 2014
It is valuable for the real world to find the opinion leaders. Because different data sources usually have different characteristics, there does not exist a standard algorithm to find and detect the opinion leaders in different data sources. Every data source has its own structural characteristics, and also has its own detection algorithm to find the ...

Game-theoretical approach for opinion dynamics on social networks

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2022
Opinion dynamics on social networks have received considerable attentions in recent years. Nevertheless, just a few works have theoretically analyzed the condition in which a certain opinion can spread in the whole structured population. In this article, we propose an evolutionary game approach for a binary opinion model to explore the conditions for ...

Efficient in‐Plane Exciton Transport in a Discontinuous Layered Lead‐Bromide Perovskite

Advanced Materials, EarlyView.
A new class of two‐dimensional lead‐bromide perovskite based on monovalent 4‐aminomethylbenzoic acid cations is presented, featuring a discontinuous inorganic layer. Despite the discontinuous lattice, transient photoluminescence microscopy demonstrates efficient though strongly anisotropic in‐plane exciton transport.

Mechanoactive Biomaterials for Cell–Matrix Mechanotransduction

Advanced Materials, EarlyView.
The graphical abstract shows how individual triggers (force, light, or temperature) and combined optothermal or receptor‐targeted actuation induce material responses at the tissue, cellular, and receptor scales. Their spatial (global or focused) and temporal (continuous or cyclic) modulation determines the resulting mechanical output.

Three-Stage Cascade Information Attenuation for Opinion Dynamics in Social Networks

Entropy
In social network analysis, entropy quantifies the uncertainty or diversity of opinions, reflecting the complexity of opinion dynamics. To enhance the understanding of how opinions evolve, this study introduces a novel approach to modeling opinion ...

Blending With Insulating Polymers Enables Stable Anti‐Ambipolar Characteristics in n‐Type Organic Mixed‐Conductors for Heterogeneous Spiking Neurons

Advanced Materials, EarlyView.
A polymer blend of n‐type OMIEC P(gNDI‐gT2) with insulating PMMA yields mechanically stabilized, anti‐ambipolar organic electrochemical transistors (OECTs) with tunable ionic‐electronic transport. This blending allows low‐power, fast‐spiking heterogeneous Hodgkin–Huxley neurons, enabling biomimetic frequency deconvolution and reservoir computing, which

Self-Presentation and Adolescent Altruistic Behaviors in Social Networks

Complexity, 2020
Social networks provide a convenient place for people to interact; members in social networks may create new connections or break existing connections, driving the evolution of complex network structure.

Forecasting elections results via the voter model with stubborn nodes

Applied Network Science, 2021
In this paper we propose a novel method to forecast the result of elections using only official results of previous ones. It is based on the voter model with stubborn nodes and uses theoretical results developed in a previous work of ours.
