Aging Modulates the Resting Brain after a Memory Task: A Validation Study from Multivariate Models
(MDPI AG, 2019)Recent work has demonstrated that aging modulates the resting brain. However, the study of these modulations after cognitive practice, resulting from a memory task, has been scarce. This work aims at examining age-related ... -
Analysis and Evaluation of a Wired/Wireless Hybrid Architecture for Distributed Control Systems With Mobility Requirements
(IEEE, 2019)Wireless communications offer significant benefits over wired communications, which has increased their popularity in industrial applications. Nevertheless, the existing wireless standard technologies do not satisfy the ... -
Application Dependent End-of-Life Threshold Definition Methodology for Batteries in Electric Vehicles
(MDPI, 2021)The end-of-life event of the battery system of an electric vehicle is defined by a fixed end-oflife threshold value. However, this kind of end-of-life threshold does not capture the application and battery characteristics ... -
Association Between Retinal Features From Multimodal Imaging and Schizophrenia
(JAMA Network, 2023)Importance. The potential association of schizophrenia with distinct retinal changes is of clinical interest but has been challenging to investigate because of a lack of sufficiently large and detailed cohorts. Objective. ... -
Association of retinal neurodegeneration with the progression of cognitive decline in Parkinson’s disease
(Springer Nature, 2024)Retinal thickness may serve as a biomarker in Parkinson’s disease (PD). In this prospective longitudinal study, we aimed to determine if PD patients present accelerated thinning rate in the parafoveal ganglion cell-inner ... -
Clinical long-term nocturnal sleeping disturbances and excessive daytime sleepiness in Parkinson's disease
(PLOS, 2021)Objective To prospectively evaluate nocturnal sleep problems and excessive daytime sleepiness (EDS) in Parkinson’s disease (PD) patients, and analyze the influence of motor symptoms, treatment, and sex differences on sleep ... -
Context-informed conditional anomaly detection approach for wave power plants: The case of air turbines
(Elsevier, 2022)The reliability and energy production of wave power plants (WPPs) depend on sea-state conditions, operation efficiency and degradation of its constituent assets. Air turbines are key assets for the efficient and reliable ... -
A Controlled Thermoalgesic Stimulation Device for Exploring Novel Pain Perception Biomarkers
(IEEE, 2021)Objective: To develop a new device for identifying physiological markers of pain perception by reading the brain's electrical activity and hemodynamic interactions while applying thermoalgesic stimulation. Methods: We ... -
A Diagnostics Framework for Underground Power Cables Lifetime Estimation Under Uncertainty
(IEEE, 2020)Power cables are critical assets for the reliable operation of the grid. The cable lifetime is generally estimated from the conductor temperature and associated lifetime reduction. However, these tasks are intricate due ... -
Efficient Calculation of Stabilization Parameters in RF Power Amplifiers
(IEEE, 2020)This paper proposes an efficient method for the calculation of the stabilization parameters in RF power amplifiers operating in periodic large-signal regimes. Stabilization is achieved by applying the principles of linear ... -
Electromechanical Properties of PVDF-Based Polymers Reinforced with Nanocarbonaceous Fillers for Pressure Sensing Applications
(MDPI AG, 2019)Polymer-based composites reinforced with nanocarbonaceous materials can be tailored for functional applications. Poly(vinylidene fluoride) (PVDF) reinforced with carbon nanotubes (CNT) or graphene with different filler ... -
Evaluation of 5G Modulation Candidates WCP-COQAM, GFDM-OQAM, and FBMC-OQAM in Low-Band Highly Dispersive Wireless Channels
(Hindawi, 2017)We analyse some of the candidates for modulations for 5G: FBMC-OQAM, GFDM-OQAM, and WCP-COQAM. Unlike most of the related bibliographies, which are oriented to mobile communications, our research is focused on 5G in cognitive ... -
Factor graph based detection approach for high-mobility OFDM systems with large FFT modes
(Springer, 2012)In this article, a novel detector design is proposed for orthogonal frequency division multiplexing (OFDM) systems over frequency selective and time varying channels. Namely, we focus on systems with large OFDM symbol ... -
Foveal Pit Morphology Characterization: A Quantitative Analysis of the Key Methodological Steps
(MDPI, 2021)Disentangling the cellular anatomy that gives rise to human visual perception is one of the main challenges of ophthalmology. Of particular interest is the foveal pit, a concave depression located at the center of the ... -
Foveal Remodeling of Retinal Microvasculature in Parkinson’s Disease
(Frontiers, 2021)Background: Retinal microvascular alterations have been previously described in Parkinson’s disease (PD) patients using optical coherence tomography angiography (OCT-A). However, an extensive description of retinal vascular ... -
Fully pipelined implementation of tree-search algorithms for vector precoding
(Hindawi, 2013)The nonlinear vector precoding (VP) technique has been proven to achieve close-to-capacity performance in multiuser multipleinput multiple-output (MIMO) downlink channels. The performance benefit with respect to its linear ... -
