Sixteen groundbreaking studies from the COSMOS Research Center, led by Prof. Nitin Agarwal, have been accepted for presentation at the 14th International Conference on Complex Networks and Their Applications (Complex Networks 2025), held in New York, USA, from December 9-11, 2025. This exceptional achievement highlights COSMOS’s continued global impact and leadership in advancing computational social science, network analytics, AI, and cognitive security. Collectively, these studies demonstrate COSMOS’s sustained excellence in developing innovative frameworks for understanding and mitigating the complexities of influence, coordination, and information dynamics across modern digital ecosystems.

The accepted papers span a diverse and intellectually rich spectrum of topics, including narrative contagion, coordinated behavior, algorithmic bias, toxic discourse propagation, and cross-platform information diffusion. Several of these studies introduce novel analytical frameworks and computational models such as CI-FSA, WFSA, ViMET-R, and Multiplex SEIRZ to identify influential groups, measure contagion effects, and quantify structural entrapment in social networks. These contributions advance the methodological frontiers of network science by offering scalable, interpretable, and data-driven approaches to capture how influence spreads, how toxicity consolidates, and how behavioral synchronization occurs across complex online communities.

Across multiple platforms, including YouTube, TikTok, and multilayer political and social networks, COSMOS’s studies have explored how persuasive, biased, or malicious narratives shape collective sentiment, public discourse, and audience engagement. By leveraging epidemiological modeling, machine learning, and multiplex network analysis, these works shed light on the cross-platform mechanisms that accelerate narrative diffusion and behavioral homogenization. They also provide actionable insights for designing interventions to enhance online transparency, detect manipulation, and strengthen digital resilience.

Together, these sixteen studies demonstrate COSMOS’s multidisciplinary research efforts, integrating social computing, behavioral-cultural modeling, AI, communication studies, and data analytics. They underscore COSMOS’s unwavering mission to safeguard the information environment and to develop scientifically grounded tools and strategies for promoting trust, integrity, and accountability in digital communication ecosystems. The breadth, innovation, and societal relevance of these contributions reaffirm COSMOS’s position at the forefront of global research on social media analytics and socio-cognitive security.
