A Mathematical Model for Two‐Phase Flow in Confined Environments: Numerical Solution and Validation
International Journal for Numerical Methods in Fluids, EarlyView.We present a numerical framework based on the Cahn‐Hilliard‐Navier‐Stokes (CHNS) model to simulate biphasic flow in confined environments. After deriving the mathematical model, we develop the weak form of the system of PDEs using a pedagogical approach to enable its implementation in FEniCS.

The Impact of Democratization and Globalization on Environmental Sustainability in Brazil
Geological Journal, EarlyView.Fossil fuel, economic globalisation, and economic growth drive environmental degradation while democratisation positively influences environmental quality. ABSTRACT Although Brazil still possesses significant ecological reserves, the surplus in its biocapacity has been rapidly declining in recent years.

Income–Well‐Being Gradient in Sickness and Health
Health Economics, EarlyView.ABSTRACT We propose a method for studying the value of insurance. For this purpose, we analyze the well‐being of the same individuals, comparing sick and healthy years, using German panel survey data on life satisfaction. We impose structure on the income–well‐being gradient by fitting a flexible utility function to the data, focusing on the ...

International Journal of Finance &Economics, EarlyView.ABSTRACT One of the critical risks associated with cryptocurrency assets is the so‐called downside risk, or tail risk. Conditional Value‐at‐Risk (CVaR) is a measure of tail risks that is not normally considered in the construction of a cryptocurrency portfolio.

International Journal of Finance &Economics, EarlyView.ABSTRACT This paper examines the relationship between economic policy uncertainty, risk aversion, and investors' attention for 15 equity indices across Asia, Europe, and North America. Our empirical results indicate that both risk aversion and economic uncertainty significantly increase the Google Search Volume across all equity indices.
