Linguistic knowledge-based vocabularies for Neural Machine Translation
(Cambridge University Press, 2020)
Article
Restricted access - publisher's policyNeural Networks applied to Machine Translation need a finite vocabulary to express textual information as a sequence of discrete tokens. The currently dominant subword vocabularies exploit statistically-discovered common ... -
Projection to latent spaces disentangles pathological effects on brain morphology in the asymptomatic phase of Alzheimer's disease
(2020-07-28)
Article
Open AccessAlzheimer's disease (AD) continuum is defined as a cascade of several neuropathological processes that can be measured using biomarkers, such as cerebrospinal fluid (CSF) levels of Aß, p-tau, and t-tau. In parallel, brain ... -
Terahertz frequency-scaled differential imaging for Sub-6 GHz vehicular antenna signature analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-10-02)
Article
Open AccessThe next generation of connected and autonomous vehicles will be equipped with high numbers of antennas operating in a wide frequency range for communications and environment sensing. The study of 3D spatial angular responses ... -
Applying cognitive dynamic learning strategies for margins reduction in operational optical networks
(2020-09-01)
Article
Restricted access - publisher's policyToday's optical transport networks are complex already and the support of the new arising services will further increase such complexity. Traditional deterministic network procedures will need to be revisited, especially ... -
Single-pass soil moisture retrievals using GNSS-R: lessons learned
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-06-01)
Article
Open AccessIn this paper, an algorithm to retrieve surface soil moisture from GNSS-R (Global Navigaton Satellite System Reflectometry) observations is presented. Surface roughness and vegetation effects are found to be the most ... -
Super-resolution of Sensinel-2 imagery using generative adversarial networks
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-07-28)
Article
Open AccessSentinel-2 satellites provide multi-spectral optical remote sensing images with four bands at 10 m of spatial resolution. These images, due to the open data distribution policy, are becoming an important resource for several ... -
Implementation of a testbed for GNSS-R payload performance evaluation
(Institute of Electrical and Electronics Engineers (IEEE), 2020-05-28)
Article
Open AccessThe functional performance of space-borne instruments must be validated on ground before and after satellite integration. The effects of radio-frequency interference are also becoming more important, even in protected bands ... -
SMOS third mission reprocessing after 10 years in orbit
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-01)
Article
Open AccessAfter more than 10 years in orbit, the SMOS team has started a new reprocessing campaign for the SMOS measurements, which includes the changes in calibration and image reconstruction that have been made to the Level 1 ... -

Article
Open AccessThis paper presents the design, manufacture and characterization of a novel 3D passive UHF-RFID tag for embedded applications. The prototype is fabricated using additive manufacturing techniques: 3D printing and copper ... -
High frequency response of thick REBCO coated conductors in the framework of the FCC study
(Nature, 2020-07-23)
Article
Open AccessA thorough microwave response study of high temperature superconductors, considered as an alternative beam screen coating, has become integral in the design decisions for CERN’s future research infrastructure. Here, we ... -
Analysis of RAN slicing for cellular V2X and mobile broadband services based on reinforcement learning
(European Alliance for Innovation n.o., 2020-03)
Article
Open AccessRadio Access Network (RAN) slicing is one of the key enablers to provide the design flexibility and enable 5G system to support heterogeneous services over a common platform (i.e., by creating a customized slice for each ... -
Modeling EDFA gain ripple and filter penalties with machine learning for accurate QoT estimation
(Institute of Electrical and Electronics Engineers (IEEE), 2020-05-01)
Article
Open AccessFor reliable and efficient network planning and operation, accurate estimation of Quality of Transmission (QoT) before establishing or reconfiguring the connection is necessary. In optical networks, a design margin is ...
