Positive ground state solutions for a class of fractional coupled Choquard systems

AIMS Mathematics, 2023
In this paper, we combine the critical point theory and variational method to investigate the following a class of coupled fractional systems of Choquard type $ \begin{equation*} \left\{ \begin{array}{l} (-\Delta)^{s}u+\lambda_{1}u& = (I_ ...

High energy amplitude in the dipole approach with Pomeron loops: asymptotic solution

, 2005
In this paper an analytical solution for the high energy scattering amplitude is suggested. This solution has several unexpected features:(i) the asymptotic amplitude is a function of dipole sizes and, therefore, this amplitude shows the gray disc ...

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

The asymptotic behaviour of perturbed evolution families

Differential and Integral Equations, 2002
This paper is devoted to the study of bounded linear operators on a complex Banach space \(X\). It is considered a \({\mathcal C}_0\)-semigroup \({\mathcal T}:=(T(t))_{t\geq 0}\), perturbed by a family \({\mathcal B}\) of closed linear operators \((B(t),D(B(t)))_{t\geq 0}\) on \(X\), fulfilling a suitable condition, and it is proved that the perturbed ...

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

Advanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Asymptotic behaviour of solutions of real two-dimensional differential system with nonconstant delay in an unstable case

Electronic Journal of Qualitative Theory of Differential Equations, 2012
The asymptotic behaviour for the solutions of a real two-dimensional system with a bounded nonconstant delay is studied under the assumption of instability. Our results improve and complement previous results by J.

Limit theorems for rank-one Lie groups [PDF]

, 2012
We investigate asymptotic behaviour of averaging operators for actions of simple rank-one Lie groups. It was previously known that these averaging operators converge almost everywhere, and we establish a more precise asymptotic formula that describes ...

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

On the convergence of solutions of nonautonomous functional differential equations

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper we study the asymptotic behaviour of solutions of delay differential equations when the right hand side of equation can be estimated by the maximum function using a new method based on the Liapunov-Razumikhin principle, differential ...

Adaptive control of a linear first-order discrete-time system providing linear-like behaviour and asymptotic tracking

Franklin Open, 2023
Adaptive control is an approach used to deal with systems having uncertain and/or time-varying parameters. In this paper, we consider the problem of designing an adaptive controller for a discrete-time first-order plant.
