Regularity Estimates for Fully Nonlinear Dead‐Core Problems With a Hamiltonian Term

Mathematische Nachrichten, EarlyView.
ABSTRACT In this paper, we present a problem involving fully nonlinear elliptic operators with Hamiltonian, which can present a singularity or degenerate as the gradient approaches the origin. The model studied here, allows the appearance of plateau zones, i.e., unknown regions of the domain in which the non‐negative solutions vanishes.

Validation of a Particle Image Velocimetry Algorithm Through Comparative Field and Laboratory Analysis

River Research and Applications, EarlyView.
ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

Beyond Growth: Governance and Education as Drivers of Environmental Health in an EKC‐Based PLS‐SEM Framework

Sustainable Development, EarlyView.
ABSTRACT Isolating environmental issues from their broader social and political context limits understanding of their true drivers. In this sense, factors such as governance and education can be powerful determinants of environmental performance. This research examines the factors influencing the Environmental Health component of the Environmental ...
