Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4184-4197, 30 March 2026.
ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

Integrating Urban Expansion and Flood Risk: A Spatial Assessment of Impervious Surface Growth and Floodplain Exposure in Mecklenburg County (2011–2021)

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Urban expansion significantly impacts flood risk, particularly in rapidly growing areas where impervious surfaces exacerbate surface runoff. This study examines spatial patterns of urban growth and their effects on flood exposure in Mecklenburg County, North Carolina, from 2011 to 2021.

Occupancy and Niche Dynamics of Iberian Freshwater Fish Across 25 Years

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 10, October 2026.
ABSTRACT Global change is reshaping biological communities, leading to shifts in community composition, species distributions and species realized niches. These processes are especially relevant in freshwater ecosystems, where vertebrate declines are particularly severe and dispersal is naturally constrained by drainage basins.

On the Properties of the Weighted Mean Residual Life in Mixtures

open access: yesApplied Stochastic Models in Business and Industry, Volume 41, Issue 6, November/December 2025.
ABSTRACT This paper focuses on the weighted mean residual life (WMRL) in mixtures of time to failure distributions. WMRL is an aging index that accounts for transformations of nonnegative random variables. The time to failure of systems operating under changing environments is described by mixtures of distributions that capture the corresponding random
