Entropy in Hydrology

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Although the concept of thermodynamic entropy due to Clausius dates back to the early 1850s, the mathematical theory of informational entropy was not developed until the pioneering work of Shannon in 1948, the development of principle of maximum entropy (POME) and theorem of concentration by Jaynes in 1957, principle of minimum cross entropy ...

Global solution for wave equation involving the fractional Laplacian with logarithmic nonlinearity

Electronic Research Archive
We construct the global existence for a wave equation involving the fractional Laplacian with a logarithmic nonlinear source by using the Galerkin approximations.

On the Lifetimes of Persistent Contrails and Contrail Cirrus

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract Prediction of contrail cirrus persistence is highly problematic for models, in part due to a poor representation of intertwined microphysical and dynamical processes controlling contrail evolution in large‐scale ice‐supersaturated areas. Knowledge of contrail cirrus lifetimes is required to estimate their lifecycle‐average radiative effect ...

Asymmetric critical fractional p-Laplacian problems

Electronic Journal of Differential Equations, 2017
We consider the asymmetric critical fractional p-Laplacian problem $$\displaylines{ (-\Delta)^s_p u = \lambda |u|^{p-2} u + u^{p^\ast_s - 1}_+,\quad \text{in } \Omega;\cr u = 0, \quad \text{in } \mathbb{R}^N\setminus\Omega; }$$ where $\lambda>0 ...

Optimization problems in rearrangement classes for fractional $ p $-Laplacian equations

Mathematics in Engineering
We discuss two optimization problems related to the fractional $ p $-Laplacian. First, we prove the existence of at least one minimizer for the principal eigenvalue of the fractional $ p $-Laplacian with Dirichlet conditions, with a bounded weight ...

The suitability of radiomics extracted from 4DCT motion‐compensated reconstruction

Journal of Applied Clinical Medical Physics, Volume 26, Issue 10, October 2025.
Abstract Purpose The most appropriate 4DCT image for radiomics analysis remains uncertain, with options including individual respiratory phases and motion‐compensated (MC) reconstructions. This study compares radiomic features derived from MC reconstructions and patient‐specific, 4D phases, evaluating their influence on feature selection, robustness to
