Superstars and Informational Cascades
, 2012 Stardom as Herding Phenomenon: The first paper of the dissertation outlines the relevance of informational cascades as an explanation for stardom in markets in which consumers have imperfect information regarding the quality of goods. Based on a cascade model, which combines informational and payoff externalities, this paper shows that stardom that has

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.

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

Cascading disasters, information cascades and continuous time models of domino effects
International Journal of Disaster Risk Reduction, 2020 This paper develops a framework for analyzing the dynamics through which cascading disasters evolve, spread and come to control in situations of uncertainty and vulnerability. The framework first establishes the idea that disasters are inherently a social phenomenon rooted in the social structure and reflects the processes of social change. The core of

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Purpose Air pollution has been linked to several neurological conditions, including stroke and neurodegenerative diseases. Evidence regarding its association with multiple sclerosis (MS) remains conflicting, limited by small sample sizes. Methods PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on ...

When half the truth is better than the truth: A Theory of aggregate information cascades [PDF]
We introduce a new model of aggregate information cascades where only one of two possible actions is observable to others. When called upon, agents (who decide in some random order that they do not know) are only informed about the total number of others
