Jan. 2026 Guozhu Ding, Zuer Liu, Shan Li , Jie Cao, Zhuohai Ye Highlights We examined opinion dynamics using LLM-based multi-agent simulation. Opinion shifts were examined across diverse simulated social community compositions. Negative mindsets show greater perspective change when influenced by others. Positive viewpoints more effective in causing opinion shifts than neutral ones. Dominant mindset in a community shapes the public opinion environment. Abstract This study exam

Jan. 2026 Ljubiša Bojić , Velibor Ilić , Veljko Prodanović   Vuk Vuković   Digital platforms now act as the primary environments for public discourse, where recommender systems shape visibility, emotion, and interpretation. This study introduces the Recommender Systems LLMs Playground (RecSysLLMsP), a simulation framework designed to examine how algorithmic personalization interacts with language generation to influence engagement and polarization. The research provides a rep

Neurophysiological tools offer objective markers of emotional reactions in multisensory environments, where positive valence promotes approach behavior and negative valence fosters avoidance. Methods: We applied the Osgoo

Nov. 2025 Abstract Background: Social media (SM) platforms have become increasingly prevalent in adolescents' lives, and concerns have arisen regarding their potential contribution to depression. This study examined whether excessive SM use contributes to rising adolescent depression rates and evaluated potential mitigation strategies. Methods and findings: We developed an individual-based microsimulation model of 18.6 million French adolescents born 1990-2012, tracking depre
