Memory-Controlled Diffusion

open access: yes, 2004
Memory effects require for their incorporation into random-walk models an extension of the conventional equations. The linear Fokker-Planck equation for the probability density $p(\vec r, t)$ is generalized to include non-linear and non-local spatial ...

Memory Effects in Online Panel Surveys: Investigating Respondents’ Ability to Recall Responses from a Previous Panel Wave

open access: yesSurvey Research Methods, 2023
If respondents recognize repeated survey questions and remember their previous responses, this can result in measurement error. Most studies to date that have investigated respondents’ recall of their prior answers have done so in the context of ...

Geometry-induced memory effects in isolated quantum systems: Observations and applications

open access: yes, 2016
Memory effects can lead to history-dependent behavior of a system, and they are ubiquitous in our daily life and have broad applications. Here we explore possibilities of generating memory effects in simple isolated quantum systems.

Memory Effects: A Comparison Across Question Types

open access: yesSurvey Research Methods, 2022
A crucial assumption of survey measurements is that respondents carefully perceive, reflect upon, and provide a response to a given question and that this process is independent of respondents’ memory of their responses to previous questions.

Memory effects in a Markov chain dephasing channel

open access: yes, 2008
We study a dephasing channel with memory, modelled by a Markov chain. We show that even weak memory effects have a detrimental impact on the performance of quantum error correcting schemes designed for uncorrelated errors.

Mathematical Model of Heat Conduction for a Semi-Infinite Body, Taking into Account Memory Effects and Spatial Correlations

open access: yesFractal and Fractional, 2023
One of the promising approaches to the description of many physical processes is the use of the fractional derivative mathematical apparatus. Fractional dimensions very often arise when modeling various processes in fractal (multi-scale and self-similar)

A simple measure of memory for dynamical processes described by the generalized Langevin equation

open access: yes, 2005
Memory effects are a key feature in the description of the dynamical systems governed by the generalized Langevin equation, which presents an exact reformulation of the equation of motion.

Scan-Rate-Dependent Ion Current Rectification in Bipolar Interfacial Nanopores

open access: yesMicromachines
This study presents a theoretical investigation into the voltammetric behavior of bipolar interfacial nanopores due to the effect of potential scan rate (1–1000 V/s). Finite element method (FEM) is utilized to explore the current–voltage (I–V) properties

Hybrid Look-Up-Tables Based Behavioral Model for Dynamic Nonlinear Power Amplifiers

open access: yesIEEE Access, 2020
A new look-up table based behavioral model for dynamic nonlinear power amplifiers is proposed. This model labelled as hybrid look-up tables model is based on the combination of a memoryless look-up table sub-model and a nested look-up tables one.
