Analysis of Bifurcation-Induced Indecisive Limit Cycles in Hybrid Opinion Dynamics with Social Attention-Controlled Consensus.
Article in IEEE control systems letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Shared beliefs in social interactions evolve through opinion exchanges governed by hybrid time scales and heterogeneous update rules. In this letter, we rigorously analyze hybrid opinion dynamics (HOD) of an interacting continuous-discrete dyad. By characterizing the HOD via a stroboscopic map, we analytically establish that high reactivity triggers a local flip bifurcation that destabilizes consensus. Following this loss of stability, the opinion trajectories enter a saturated plateau-switching regime and converge to a stable indecisive limit cycle representing a persistent cyclic deadlock. Leveraging Floquet theory and a Lyapunov-based cycle-to-cycle contraction, we prove the asymptotic stability of these oscillations. Finally, we propose a social-attention-based control law that guarantees a transition from cyclic deadlock to consensus.
