A study of the hydrostatic mass bias dependence and evolution within The Three Hundred clusters [PDF]
, 2022 We use a set of about 300 simulated clusters from The Three Hundred Project to calculate their hydrostatic masses and evaluate the associated bias by comparing them with the true cluster mass. Over a redshift range from 0.07 to 1.3, we study the dependence of the hydrostatic bias on redshift, concentration, mass growth, dynamical state, mass, and halo ...

Dynamics of Public Opinion Evolution with Asymmetric Cognitive Bias [PDF]
arXiv, 2021 In this paper, we propose a pubic opinion model with incorporation of asymmetric cognitive bias: confirmation bias and negativity bias. We then investigate the generic modeling guidance of capturing asymmetric confirmation bias and negativity bias. A numerical examples is provided to demonstrate the correctness of asymmetric cognitive bias model.

Analysis of Media Writing Style Bias through Text-Embedding Networks [PDF]
arXiv, 2023 With the rise of phenomena like `fake news' and the growth of heavily-biased media ecosystems, there has been increased attention on understanding and evaluating media bias. Of particular note in the evaluation of media bias is writing style bias, which includes lexical bias and framing bias. We propose a novel approach to evaluating writing style bias

PLoS ONE, 2020 Strategies to identify and mitigate publication bias and outcome reporting bias are frequently adopted in systematic reviews of clinical interventions but it is not clear how often these are applied in systematic reviews relating to quantitative health ...

Medicine, 2019 Publication bias is a type of systematic error when synthesizing evidence that cannot represent the underlying truth. Clinical studies with favorable results are more likely published and thus exaggerate the synthesized evidence in meta-analyses.

Riesgo de sesgo de publicación en intervenciones terapéuticas para la COVID-19
Revista Panamericana de Salud Pública, 2021 This article describes publication bias, its most frequent causes, its characteristics, the regulatory tools to avoid it, and some statistical techniques to analyze it. These techniques are explained and applied to three therapeutic interventions related
