Identifying causal subsequent memory effects. [PDF]
Proc Natl Acad Sci U S A, 2023 AbstractOver 40 years of accumulated research has detailed associations between neuroimaging signals measured during a memory encoding task and later memory performance, across a variety of brain regions, measurement tools, statistical approaches and behavioral tasks.

Memory Effects, Multiple Time Scales and Local Stability in Langevin Models of the S&P500 Market Correlation [PDF]
Entropy, 2023 The analysis of market correlations is crucial for optimal portfolio selection of correlated assets, but their memory effects have often been neglected.

Physical Origins of Memory Effects in a Non-Markovian Quantum Evolution [PDF]
EntropyWe quantitatively investigate the physical origins of the non-Markovianity measure proposed in our previous work, which can be directly interpreted as memory effects, i.e., the dependence of a quantum system’s future evolution on its history.

Memory Effects in Quantum Dynamics Modelled by Quantum Renewal Processes [PDF]
Entropy, 2021 Simple, controllable models play an important role in learning how to manipulate and control quantum resources. We focus here on quantum non-Markovianity and model the evolution of open quantum systems by quantum renewal processes.

Memory Effects in High-Dimensional Systems Faithfully Identified by Hilbert–Schmidt Speed-Based Witness [PDF]
Entropy, 2022 A witness of non-Markovianity based on the Hilbert–Schmidt speed (HSS), a special type of quantum statistical speed, has been recently introduced for low-dimensional quantum systems.

IEEE Access, 2022 This paper proposes a novel predistorter architecture suitable for hybrid baseband/RF implementation. The distortion function is split into a memory polynomial and an AM/AM only look-up table (LUT).

Work Extraction and Performance of Colloidal Heat Engines in Viscoelastic Baths
Frontiers in Physics, 2021 A colloidal particle embedded in a fluid can be used as a microscopic heat engine by means of a sequence of cyclic transformations imposed by an optical trap.

Journal of High Energy Physics, 2019 Abstract In systems with local gauge symmetries, the memory effect corresponds to traces inscribed on a suitable probe when a pure gauge configuration at infinite past dynamically evolves to another pure gauge configuration at infinite future.

Nonlinear optical memory effect [PDF]
Optics Letters, 2019 Light propagating through random media produces characteristic speckle patterns, directly related to the large multitude of scattering events. These complex dynamics remarkably display robustness to perturbation of the incoming light parameters, maintaining correlation in the scattered wavefront.

Shape memory effect and properties memory effect of polyurethane [PDF]
Journal of Applied Polymer Science, 2012 AbstractThe relationship between shape and properties memory effect, especially viscoelastic properties of polyurethane under study is the main aim of this research work. Tensile tests have been performed in order to introduce 100% of deformation in the polyurethane samples.
