On S-2-absorbing submodules and vn-regular modules

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
Let R be a commutative ring and M an R-module. In this article, we introduce the concept of S-2-absorbing submodule. Suppose that S ⊆ R is a multiplicatively closed subset of R.

The role of child language ability and parental mentalization in early child dysregulation

Infant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 1, January 2026.
Abstract Dysregulation in early childhood is associated with increased vulnerability to psychopathology and poor psychosocial outcomes. While there is evidence that both child language ability and parental mentalization are associated with dysregulation in early childhood, there is little understanding of the relationships between these variables, and ...

Fine‐scale reconstruction of pelagic fish migration by iso‐logging of eye lens

Methods in Ecology and Evolution, Volume 17, Issue 1, Page 77-84, January 2026.
Abstract Understanding lifetime space use by pelagic animals is pivotal for ecology and fisheries management, but electronic tags are costly, labour‐intensive and rarely able to capture juvenile movement. We implemented an iso‐logging workflow that converts stable isotope chronologies in eye lenses into continuous migration tracks, and demonstrate its ...

On an uncertainty principle for small index subgroups of finite fields

Open Mathematics
In this article, we continue the study of the nonvanishing minors property initiated by Garcia, Karaali, and Katz, for the compressed Fourier matrix attached to a subgroup HH of the multiplicative group of a finite field Fq{{\mathbb{F}}}_{q} and a ...

On Efficient Iterative Algorithms and Conditioning for the Nonlinear Sylvester Equation

Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.
Nonlinear Sylvester‐type matrix equations arise in applications such as control theory, observer design, model reduction, and data‐driven systems, where they model higher order interactions in matrix transformations. Unlike the classical Sylvester equation, the presence of nonlinear terms introduces additional analytical challenges and increased ...

On certain properties and expansions of zeta matrix function, digamma matrix function and polygamma matrix function

, 2020
We introduce the generalized zeta matrix function, digamma matrix function and polygamma matrix function. We obtain the regions of convergence of these matrix functions, some recurrence relations and their integral representations.
