A finite difference method for piecewise deterministic processes with memory. II

open access: yesMathematical Modelling and Analysis, 2009
We deal with the numerical scheme for the Liouville Master Equation (LME) of a kind of Piecewise Deterministic Processes (PDP) with memory, analysed in [2].

Generalized Fractional Processes with Long Memory and Time Dependent Volatility Revisited

open access: yesEconometrics, 2016
In recent years, fractionally-differenced processes have received a great deal of attention due to their flexibility in financial applications with long-memory.

Contribution of underlying processes to improved visuospatial working memory associated with physical activity [PDF]

open access: yesPeerJ, 2017
Background Working memory is critical for various cognitive processes and can be separated into two stages: short-term memory storage and manipulation processing.

The Periodogram of fractional processes [PDF]

open access: yes, 2007
We analyse asymptotic properties of the discrete Fourier transform and the periodogram of time series obtained through (truncated) linear filtering of stationary processes.

Memory for Light as a Quantum Process [PDF]

open access: yesPhysical Review Letters, 2009
We report complete characterization of an optical memory based on electromagnetically induced transparency. We recover the superoperator associated with the memory, under two different working conditions, by means of a quantum process tomography technique that involves storage of coherent states and their characterization upon retrieval.

Context and target recollection for words and pictures in young adults with developmental dyslexia

open access: yesFrontiers in Psychology, 2022
IntroductionThe specificity of memory functioning in developmental dyslexia is well known and intensively studied. However, most research has been devoted to working memory, and many uncertain issues about episodic memory remain practically unexplored ...

Real Processing-in-Memory with Memristive Memory Processing Unit (mMPU) [PDF]

open access: yes2019 IEEE 30th International Conference on Application-specific Systems, Architectures and Processors (ASAP), 2019
Memristive technologies are attractive candidates to replace conventional memory technologies and can also be used to perform logic and arithmetic operations. In this paper, we show how memristors are used to combine data storage and computation in the memory, thus enabling a novel non-von Neumann architecture called the 'memristive memory processing ...

Periodically Kicked Rotator with Power-Law Memory: Exact Solution and Discrete Maps

open access: yesFractal and Fractional
This article discusses the transformation of a continuous-time model of the fractional system into a discrete-time model of the fractional system. For the continuous-time model, the exact solution of the nonlinear equation with fractional derivatives ...

Neural mechanisms associated with semantic and basic self-oriented memory processes interact moderating self-esteem

open access: yesiScience, 2022
Summary: Individuals constantly encounter feedback from others and process this feedback in various ways to maintain positive situational state self-esteem in relation to semantic-based or trait self-esteem.

Hormonal and genetic modulation of memory processes in healthy humans: focus on cortisol and "HDAC5" [PDF]

open access: yes, 2015
Individual differences in memory performance can be due to the influence of various hormones as well as genetic variations and epigenetic modifications.
