Unraveling Hierarchical Brain Dysfunction in Major Depressive Disorder: A Multimodal Imaging and Transcriptomic Approach. [PDF]

open access: yesHum Brain Mapp
Dysfunctional hierarchy in major depressive disorder (MDD) features decreased SDI in regions linked to high‐order cognitive functions, like the prefrontal, parietal, and orbitofrontal cortices. Conversely, areas related to low‐level sensory‐motor functions, the somatosensory cortex, showed increased SDI in MDD.

PULLBACK AND FORWARD ATTRACTORS FOR A DAMPED WAVE EQUATION WITH DELAYS [PDF]

open access: greenStochastics and Dynamics, 2004
The existence of a pullback (and also a uniform forward) attractor is proved for a damped wave equation containing a delay forcing term which, in particular, covers the models of sine–Gordon type. The result follows from the existence of a compact set which is uniformly attracting for the two-parameter semigroup associated to the model.

Pullback attractors of nonautonomous dynamical systems

open access: bronzeDiscrete & Continuous Dynamical Systems - A, 2006
We present the necessary and sufficient conditions and a new method to study the existence of pullback attractors of nonautonomous infinite dimensional dynamical systems. For illustrating our method, we apply it to nonautonomous 2D Navier-Stokes systems.

Pullback Attractor for Nonautonomous Ginzburg-Landau Equation with Additive Noise

open access: yesAbstract and Applied Analysis, 2014
Long time behavior of stochastic Ginzburg-Landau equations with nonautonomous deterministic external forces, dispersion coefficients, and nonautonomous perturbations is studied. The domain is taken as a bounded interval I in R.

The pullback attractor for the 2D g-Navier-Stokes equation with nonlinear damping and time delay

open access: yesAIMS Mathematics, 2023
In this article, the global well-posedness of weak solutions for 2D non-autonomous g-Navier-Stokes equations on some bounded domains were investigated by the Faedo-Galerkin method.

Pullback attractor for a weakly damped wave equation with sup-cubic nonlinearity

open access: yesDiscrete and Continuous Dynamical Systems. Series A, 2021
In this paper, the non-autonomous dynamical behavior of weakly damped wave equation with a sup-cubic nonlinearity is considered in locally uniform spaces.

Continuity of pullback and uniform attractors [PDF]

open access: yesJournal of Differential Equations, 2018
We study the continuity of pullback and uniform attractors for non-autonomous dynamical systems with respect to perturbations of a parameter. Consider a family of dynamical systems parameterised by a complete metric space $ $ such that for each $ \in $ there exists a unique pullback attractor $\mathcal A_ (t)$. Using the theory of Baire category we

Statistical solution and piecewise Liouville theorem for the impulsive discrete Zakharov equations

open access: yesAIMS Mathematics, 2022
This article studies the discrete Zakharov equations with impulsive effect. The authors first prove that the problem is global well-posed and that the process formed by the solution operators possesses a pullback attractor. Then they establish that there

Existence of pullback attractors for pullback asymptotically compact processes [PDF]

open access: yesNonlinear Analysis: Theory, Methods & Applications, 2010
This paper is concerned with the existence of pullback attractors for evolution processes. Our aim is to provide results that extend the following results for autonomous evolution processes (semigroups) i) An autonomous evolution process which is bounded dissipative and asymptotically compact has a global attractor.
