Optical conductivity and optical effective mass in a high-mobility organic semiconductor: Implications for the nature of charge transport [PDF]
, 2014 We present a multiscale modeling of the infrared optical properties of the rubrene crystal. The results are in very good agreement with the experimental data that point to nonmonotonic features in the optical conductivity spectrum and small optical ...

In‐Sensor Computing by Soft Threshold Logic Gates Under Different Humidity Conditions
Advanced Electronic Materials, EarlyView.Soft nanocomposite materials, based on gold cluster‐assembled thin films implanted in polydimethylsiloxane substrate, can perform reliable processing in ambient environmental conditions. Humidity influences the resistive switching and computational capabilities of the nanocomposites, that can be used as multifunctional material combining sensing ...

Statics of nonlocal stress driven graded material beam - cauchy distribution approach
Applications in Engineering ScienceNonlocal elasticity theories are essential for modeling size-dependent mechanical behavior in micro- and nano-structured components, yet existing stress-driven formulations rely almost exclusively on rapidly decaying kernels such as the Helmholtz or ...

Nonlocal amplification of intense vorticity in turbulent flows
Physical Review Research, 2021 The nonlinear and nonlocal coupling of vorticity and strain rate constitutes a major hindrance in understanding the self-amplification of velocity gradients in turbulent fluid flows.

Quark-hybrid matter in the cores of massive neutron stars [PDF]
, 2012 Using a nonlocal extension of the SU(3) Nambu-Jona Lasinio model, which reproduces several of the key features of Quantum Chromodynamics, we show that mixed phases of deconfined quarks and confined hadrons (quark-hybrid matter) may exist in the cores of ...

CHIMERA STATES IN A RING OF NONLOCALLY COUPLED OSCILLATORS [PDF]
International Journal of Bifurcation and Chaos, 2006 Arrays of identical limit-cycle oscillators have been used to model a wide variety of pattern-forming systems, such as neural networks, convecting fluids, laser arrays and coupled biochemical oscillators. These systems are known to exhibit rich collective behavior, from synchrony and traveling waves to spatiotemporal chaos and incoherence.

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws
Advanced Intelligent Discovery, EarlyView.The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Material‐Based Intelligence: Autonomous Adaptation and Embodied Computation in Physical Substrates
Advanced Intelligent Systems, EarlyView.This perspective formulates a unifying framework for Material‐Based Intelligence (MBI), defining the physical requirements for materials to achieve embodied action, active memory and embodied information processing through intrinsic nonequilibrium dynamics. The design of intelligent materials often draws parallels with the complex adaptive behaviors of

On Nonlinear Coupled System with Nonlocal Boundary Conditions
Boletim da Sociedade Paranaense de Matemática, 2003 Summary: We discuss the existence, uniqueness and stability exponential and polynomial of global solutions for a nonlinear coupled system with nonlocal boundary conditions given by \[ \begin{aligned} u_{tt}+\Delta^2u+f(u-v) & =0\text{ in }\Omega\times (0,\infty),\\ v_{tt}-\Delta v-f(u-v)& =0\text{ in }\Omega\times(0,\infty),\\ u=0 \text{ on }\Gamma_0 ...

Role of nonlocal heat transport on the laser ablative Rayleigh-Taylor instability
Nuclear FusionAblative Rayleigh–Taylor instability (ARTI) and nonlocal heat transport are the critical problems in laser-driven inertial confinement fusion, while their coupling with each other is not completely understood yet.
