Leaf‐wood classification of terrestrial laser scanning data with co‐registered near‐infrared photography

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 7, Page 1425-1436, July 2025.
Abstract Due to their importance for climate change monitoring, modelling and adaptation, vegetation structural properties including leaf area index (LAI) are designated essential climate variables (ECVs) by the Global Climate Observing System (GCOS).

Fractional variational principles with delay within caputo derivatives

open access: yesReports on Mathematical Physics, 2010
In this paper we investigate the fractional variational principles within Caputo derivatives in the presence of delay derivatives. The corresponding Euler-Lagrange equations are obtained for the case of one dependent variable. A generalization to n dependent variables is obtained. Physical example is analyzed in detail.

Plant‐Based versus Conventional Meat in Food Away From Home Settings: Substitution, Complementarity, and Market Impacts

open access: yesAgricultural Economics, Volume 56, Issue 4, Page 587-603, July 2025.
ABSTRACT Evidence regarding whether consumers view plant‐based meat alternatives (PBMAs) as substitutes for or complements to meat is mixed; however, the ultimate effect of increased demand for PBMAs on poultry and livestock production depends on this relationship.

Stability of solutions to impulsive Caputo fractional differential equations

open access: yesElectronic Journal of Differential Equations, 2016
Stability of the solutions to a nonlinear impulsive Caputo fractional differential equation is studied using Lyapunov like functions. The derivative of piecewise continuous Lyapunov functions among the nonlinear impulsive Caputo differential equation ...
