Several Characterizations of the Generalized 1-Parameter 3-Variable Hermite Polynomials
MathematicsThis paper presents a novel framework for introducing generalized 1-parameter 3-variable Hermite polynomials. These polynomials are characterized through generating functions and series definitions, elucidating their fundamental properties.

Oikos, Volume 2026, Issue 10, October 2026.In temperate lakes, plankton dynamics are closely linked to seasonal shifts in water stratification, following air temperature. The onset of summer stratification typically coincides with the formation of an algal spring bloom in the well‐mixed surface layer (epilimnion).

geohabnet: An R package for mapping habitat connectivity for biosecurity and conservation
Methods in Ecology and Evolution, Volume 17, Issue 10, Page 2862-2872, October 2026.Abstract Habitat connectivity is critical for the conservation of endangered and endemic species, and conversely, it can hinder efforts to contain the spread of harmful biological agents. Here, we introduce geohabnet: a general, spatially explicit, network‐based R package for evaluating, estimating and mapping landscape connectivity from continuous ...

Individual bird identification by modelling temporal structure in bioacoustic embeddings
Methods in Ecology and Evolution, Volume 17, Issue 10, Page 2909-2927, October 2026.Abstract Identifying individual animals from vocalizations is an emerging research area in computational bioacoustics. This non‐invasive approach reduces reliance on physical capture and tagging for wildlife monitoring. Recent advances in this area leverage deep learning and bioacoustic foundation models adapted from species‐level classifiers. However,

Free integro-differential algebras and Groebner-Shirshov bases [PDF]
, 2014 The notion of commutative integro-differential algebra was introduced for the algebraic study of boundary problems for linear ordinary differential equations. Its noncommutative analog achieves a similar purpose for linear systems of such equations.

Bounder solution on a strip to a system of nonlinear hyperbolic equations with mixed derivatives
Қарағанды университетінің хабаршысы. Математика сериясы, 2016 The system of nonlinear hyperbolic equations with mixed derivatives is considered on the strip. Time variable of the unknown function changes on the whole axis, and the spatial variable belongs to a finite interval.

Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies
Mathematical Finance, Volume 36, Issue 4, Page 804-825, October 2026.ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

Dam Management in the Era of Climate Change
Mathematical Finance, Volume 36, Issue 4, Page 870-895, October 2026.ABSTRACT Climate change has a dramatic impact, particularly by concentrating rainfall into a few short periods, interspersed with long dry spells. In this context, the role of dams is crucial. We consider the optimal control of a dam, where the water level must neither exceed a designated safety threshold nor fall below a minimum level to ensure ...
