Moving discrete breathers in a β-FPU lattice revisited
(Elsevier, 2022-08)
In this work we revisit the existence, stability and dynamical properties of moving discrete breathers in -FPU lattices. On the existence side, we propose a numerical procedure, based on a continuation along a sequence of ...

Enhanced Stability of Perovskite Solar Cells Incorporating Dopant-Free Crystalline Spiro-OMeTAD Layers by Vacuum Sublimation
(Wiley-Blackwell, 2020)
The main handicap still hindering the eventual exploitation of organometal halide perovskite-based solar cells is their poor stability under prolonged illumination, ambient conditions, and increased temperatures. This ...

About the Structure of Attractors for a Nonlocal Chafee-Infante Problem
(MDPI, 2021)
In this paper, we study the structure of the global attractor for the multivalued semiflow generated by a nonlocal reaction-diffusion equation in which we cannot guarantee the uniqueness of the Cauchy problem. First, we ...

Synchrony Matters More than Species Richness in Plant Community Stability at a Global Scale
(National Academy of Sciences, 2020)
The stability of ecological communities is critical for the stable provisioning of ecosystem services, such as food and forage production, carbon sequestration, and soil fertility. Greater biodiversity is expected to enhance ...

Stability of regular attractors for non-autonomous random dynamical systems and applications to stochastic Newton-Boussinesq equations with delays
(Elsevier, 2023-10-03)
In this paper, we establish theoretical results on the stability of random regular attractors. First, we introduce a backward regular attractor, which is a new type of attractor defined by a minimal backward pullback ...

A study of the dynamic changes of stability taking place during virgin olive oil storage period examined by mesh cell-FTIR spectroscopy
(Elsevier, 2022)
Virgin olive oil (VOO) stability needs to be controlled to guarantee that the oil keeps the quality declared on the label during distribution. However, the stability is changing as storage progresses and its estimation ...

Stability of traveling waves in a driven Frenkel–Kontorova model
(Elsevier, 2020-06)
In this work we revisit a classical problem of traveling waves in a damped Frenkel–Kontorova lattice driven by a constant external force. We compute these solutions as fixed points of a nonlinear map and obtain the ...

Stability of solitary waves in nonlinear Klein-Gordon equations
(IOP Publishing, 2022-11)
The stability of topological solitary waves and pulses in one-dimensional nonlinear Klein–Gordon systems is revisited. The linearized equation describing small deviations around the static solution leads to a Sturm–Liouville ...

Stability of fractionally dissipative 2D quasi-geostrophic equation with infinite delay
(Springer, 2020-08-18)
In this paper, fractionally dissipative 2D quasi-geostrophic equations with an external force containing infinite delay is considered in the space Hs with s ≥ 2 − 2α and α ∈ ( 1 2 , 1). First, we investigate the existence ...

New examples of subsets of c with the FPP and stability of the FPP in hyperconvex spaces
(Springer, 2021-07-22)
The purpose of this work is two-fold. On the one side, we focus on the space of real convergent sequences c where we study non-weakly compact sets with the fixed point property. Our approach brings a positive answer to a ...
