School of Economics, Beijing Institute of Technology, Beijing, China; GUST Center for Sustainable Development (CSD), Gulf University for Science and Technology, Hawally, Kuwait; University of Economics and Human Science in Warsaw, Warsaw, Poland. Electronic address:

This study analyses the influence of environmental taxes, renewable energy, economic growth, green innovation and financial development on environmental sustainability in G-20 countries from 1990 to 2022. To this end, the Method of Moments Quantile Regression (MMQR) was applied to obtain the reference results, complemented with Fully Modified Ordinary Least Square (FMOLS) and Driscoll-Kraay techniques to perform a comparative analysis. Our results confirm a negative relationship between environmental taxes and sustainability in all quantiles, although this relationship is only significant in the middle and upper quantiles.

Background: Accurate distinction between stroke etiologic subtypes is critical for physicians to provide tailored treatment. The triglyceride-glucose (TyG) index, a marker of insulin resistance, has been associated with stroke risk but its role in distinguishing stroke etiologic subtypes remains unclear. We aimed to assess the TyG index's ability to differentiate cardioembolic (CE) from non-cardioembolic (NCE) strokes.
