open access: yesJournal of Mathematical Extension, 2012
In this work, the modified Laplace Adomian decomposition method (LADM) is applied to solve the integro-differential equations. In addition, examples that illustrate the pertinent features of this method are presented, and the results of the study are ...

Solving linear systems of fractional integro-differential equations by Haar and Legendre wavelets techniques

open access: yesPartial Differential Equations in Applied Mathematics
In this study, we present two highly effective approaches aimed at solving linear systems of equations, specifically focusing on the Fredholm and Volterra equations in fractional integro-differential formula.

A construction of analog of Fredgolm theorems for one class of first order model integro-differential equation with logarithmic singularity in the kernel

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
The integral representations of the solution manifold for one class of the first order model integro-differential equation with logarithmic singularity in the kernel are constructed using arbitrary constants. The cases when the given integro-differential

Wood density variation across an Andes‐to‐Amazon elevational gradient

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2370-2385, September 2025.
We study how wood density varies along a 3500‐m elevational gradient, spanning from the Andean tree line to the Amazon basin. Our results reveal that wood density decreases from low to mid‐elevations, then increases toward the tree line. These patterns underscore the influence of species composition, life forms such as tree ferns, and local ...

Distinguishing passive and driven trait evolution in the presence of boundaries

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 9, Page 2067-2081, September 2025.
Abstract Quantifying the dynamics of macroevolutionary trends, such as changes in body size and complexity, is vital for understanding the processes that have shaped patterns of extant and extinct biodiversity. For example, whilst maximum body size may tend to increase within lineages (the Cope‐Depéret rule), it is still unclear whether such patterns ...

Propagation of chaos in neural fields

open access: yes, 2014
We consider the problem of the limit of bio-inspired spatially extended neuronal networks including an infinite number of neuronal types (space locations), with space-dependent propagation delays modeling neural fields.

Optimal control of axial dispersion tubular reactors with recycle: Addressing state‐delay through transport PDEs

open access: yesThe Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3751-3766, August 2025.
The boundary‐regulated distributed parameter system of an axial dispersion tubular reactor with delayed recycle is showcased, along with the optimal observer‐based control strategy developed using a late‐lumping method for its stabilization. Abstract The optimal control of an axial tubular reactor with a recycle stream is addressed as a key type of ...
