Nonlinear Opinion Dynamics With Tunable Sensitivity [PDF]
, 2023 peer reviewedWe propose a continuous-time multioption nonlinear generalization of classical linear weighted-average opinion dynamics. Nonlinearity is introduced by saturating opinion exchanges, and this is enough to enable a significantly greater range ...

Entropy, 2020 We analyze a nonlinear q-voter model with stochastic noise, interpreted in the social context as independence, on a duplex network. The size of the lobby q (i.e., the pressure group) is a crucial parameter that changes the behavior of the system.

Opinion dynamics for agents with opinion-dependent connections [PDF]
49th IEEE Conference on Decision and Control (CDC), 2010 We study a simple continuous-time multi-agent system related to Krause's model of opinion dynamics: each agent holds a real value, and this value is continuously attracted by every other value differing from it by less than 1, with an intensity proportional to the difference.

Generalized Solutions to Opinion Dynamics Models with Discontinuities [PDF]
, 2021 Social dynamics models may present discontinuities in the right-hand side of the dynamics for multiple reasons, including topology changes and quantization.

Opinion dynamics with highly oscillating opinions
NeurocomputingOpinion Dynamics (OD) models are a particular case of Agent-Based Models in which the evolution of opinions within a population is studied. In most OD models, opinions evolve as a consequence of interactions between agents, and the opinion fusion rule defines how those opinions are updated. In consequence, despite being simplistic, OD models provide an

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...
