Combining Software-Defined Radio Learning Modules and Neural Networks for Teaching Communication Systems Courses †
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
The paradigm known as Cognitive Radio (CR) proposes a continuous sensing of the electromagnetic spectrum in order to dynamically modify transmission parameters, making intelligent use of the environment by taking advantage ...

Hydrogen sulfide action in the regulation of plant autophagy
(Wiley-Blackwell, 2022)
Hydrogen sulfide is a signalling molecule with a well-established impact on both plant and animal physiology. Intense investigation into the regulation of autophagy by sulfide in Arabidopsis thaliana has revealed that the ...

Influential factors and barriers change along the invasion continuum of an alien plant
(Springer Nature, 2023-06-12)
Upon arrival to a new area, alien species have to overcome a series of biotic and abiotic barriers to survive, reproduce, and spread and thus, succeed along the invasion continuum. Failing to understand the role of the ...

Buckling in a Rotationally Invariant Spin-elastic Model
(American Physical Society, 2023)
Scanning tunneling microscopy experiments have revealed a spontaneous rippled-to-buckled transition in heated graphene sheets, in absence of any mechanical load. Several models relying on a simplified picture of the ...

A facial authentication system using post-quantum-secure data generated on mobile devices
(2022)
This paper describes a demonstrator of a post-quantum-secure facial authentication system distributed between a mobile device acting as a client and a remote computer acting as an authentication server. Homomorphic encryption ...

A role for the Saccharomyces cerevisiae Rtt109 histone acetyltransferase in R-loop homeostasis and associated genome instability
(Genetics Society of America, 2022)
The stability of the genome is occasionally challenged by the formation of DNA-RNA hybrids and R-loops, which can be influenced by the chromatin context. This is mainly due to the fact that DNA-RNA hybrids hamper the ...

Highly Dispersed Rh Single Atoms over Graphitic Carbon Nitride as a Robust Catalyst for the Hydroformylation Reaction
(Royal Society of Chemistry, 2023)
Rhodium-catalysed hydroformylation, effective tool in bulk and fine-chemical synthesis, predominantly uses soluble metal complexes. For that reason, the metal leaching and the catalyst recycling are still the major drawbacks ...

H2 Production from NH3 in a BaTiO3 Moderated Ferroelectric Packed-Bed Plasma Reactor
(Springer Nature, 2023)
Plasma decomposition reactions are used for various gas phase chemical processes including the decomposition of ammonia. In this work we show that pure ammonia can be effectively decomposed at atmospheric pressure and ...

Tackling unbalanced datasets for yellow and brown rust detection in wheat
(Frontiers, 2024-05)
This study evaluates the efficacy of hyperspectral data for detecting yellow and brown rust in wheat, employing machine learning models and the SMOTE (Synthetic Minority Oversampling Technique) augmentation technique to ...

New detection systems for an enhanced sensitivity in key stellar (n,gamma) measurements
(E D P Sciences, 2023)
Neutron capture cross-section measurements are fundamental in the study of astrophysical phenomena, such as the slow neutron capture (s-) process of nucleosynthesis operating in red-giant and massive stars. However, neutron ...
