Pattern Formation and Nonlinear Waves Close to a 1:1 Resonant Turing and Turing–Hopf Instability
Studies in Applied Mathematics, Volume 155, Issue 5, November 2025.ABSTRACT In this paper, we analyze the dynamics of a pattern‐forming system close to simultaneous Turing and Turing–Hopf instabilities, which have a 1:1 spatial resonance, that is, they have the same critical wave number. For this, we consider a system of coupled Swift–Hohenberg equations with dispersive terms and general, smooth nonlinearities.

A parameter uniform fitted mesh method for a weakly coupled system of two singularly perturbed convection-diffusion equations [PDF]
, 2018 In this paper, a boundary value problem for a singularly perturbed linear system of two second order ordinary differential equations of convection- diffusion type is considered on the interval [0, 1]. The components of the solution of this system exhibit

Current Practices for Analyzing Soils and Sediments via Mössbauer Spectroscopy
Journal of Plant Nutrition and Soil Science, Volume 188, Issue 5, Page 742-773, October 2025.ABSTRACT Environmental scientists are increasingly returning to Mössbauer spectroscopy (MBS) to reveal details about iron (Fe)‐bearing phases in soils and sediments. MBS is particularly powerful at distinguishing between Fe(II) and Fe(III) and, given appropriate background information, can offer exceptionally precise information on Fe speciation in ...

Business Ethics, the Environment &Responsibility, Volume 34, Issue 4, Page 1412-1431, October 2025.Abstract Constructive Deviant Behavior (CDB) raises an ethical dilemma that poses a significant challenge within the realm of business ethics. This ethical dilemma is the extent to which individuals should be allowed, or even encouraged, to challenge established norms in the name of organizational and stakeholder well‐being before compromising ethical ...

Singularly perturbed rank one linear operators
Математичні Студії, 2021 The basic principles of the theory of singularly perturbed self-adjoint operators are generalized to the case of closed linear operators with non-symmetric perturbation of rank one.

Disentangling the effects of climate change in a mountain lake through community structure analysis
Limnology and Oceanography, Volume 70, Issue 8, Page 2142-2157, August 2025.Abstract Pressures of climate change may trigger regime shifts in ecosystems. Identifying signs of these pressures before the critical transition remains challenging, and it could be useful to anticipate the regime shift. In this research, while exploiting the case of a lacustrine ecosystem, which passed from an unvegetated, phytoplankton‐dominated ...
