The phase-space view of non-local gravity cosmology
Physics Letters B, 2022 We consider non-local Integral Kernel Theories of Gravity in a homogeneous and isotropic universe background as a possible scenario to drive the cosmic history.

Exponential attractors for nonautonomous partially dissipative equations
Differential and Integral Equations, 1999 The following problem in a Hilbert space \(H\) is considered: \(u'(t)={\mathcal G} (\alpha ,t,u(t)),\) \(t>\tau ,\) \(u(\tau)=u_\tau \in H,\) where \(\tau \in \mathbb{R}\), \(\alpha =(\alpha _1,\dots ,\alpha _k)\) with \(\alpha _i\) rationally independent and \({\mathcal G}(\omega _1,\dots ,\omega _k,\cdot)\) is \(2\pi \)-periodic in each \(\omega _i.\)

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Global Stability of Approximation for Exponential Attractors
Funkcialaj Ekvacioj, 2004 This paper is concerned with the initial value problem for some diffusion system which describes the process of a pattern formation of biological individuals by chemotaixis and growth. In the paper Osaki et al. [13], exponential attractors have been constructed for the dynamical system determined by this problem.

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Delay-Dependent Dynamics of Switched Cohen-Grossberg Neural Networks with Mixed Delays
Abstract and Applied Analysis, 2013 This paper aims at studying the problem of the dynamics of switched Cohen-Grossberg neural networks with mixed delays by using Lyapunov functional method, average dwell time (ADT) method, and linear matrix inequalities (LMIs) technique.

Statistical properties of Lorenz like flows, recent developments and perspectives
, 2014 We comment on mathematical results about the statistical behavior of Lorenz equations an its attractor, and more generally to the class of singular hyperbolic systems.

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.
