Methodology for determining the threshold distance for estimating the main EM exposure contribution in WLAN
(Elsevier, 2021-05-25)
The location of radiation sources in wireless networks is a key factor to characterize their contribution to electromagnetic exposure levels in order to deploy future networks that account for minimizing electromagnetic ...
Dielectric spectroscopy of a ferroelectric nematic liquid crystal and the effect of the sample thickness
(Elsevier, 2023-10)
The recently discovered ferroelectric nematic liquid crystals have been reported to exhibit very large dielectric permittivity values. Here, we report a systematic investigation of the dielectric behavior of a prototypical ...
(Re)translation and Reception of Neologisms in Science Fiction: A Methodological Proposal
(UCOPress, 2020-08-02)
This paper proposes a new methodology for studying neologismsin the translation and retranslation of the science fiction novel Altered Carbon (Richard Morgan,2001), its adaptation as a TV series by Netflix ...
Open access dataset of task-free hemodynamic activity in 4-monthold infants during sleep using fNIRS
(NATURE RESEARCH, 2022)
Spontaneous, task-free, hemodynamic activity of the brain provides useful information about its functional organization, as it can describe how different brain regions communicate to each other. Neuroimaging studies measuring ...
Training Design, Performance Analysis, and Talent Identification—A Systematic Review about the Most Relevant Variables through the Principal Component Analysis in Soccer, Basketball, and Rugby
(MDPI, 2021-03-05)
Since the accelerating development of technology applied to team sports and its subsequent high amount of information available, the need for data mining leads to the use of data reduction techniques such as Principal ...
Using Ultra-Wide Band to Analyze Soccer Performance through Load Indicators during a Full Season: A Comparison between Starters and Non-Starters
(MDPI, 2022-12-10)
The objectives of this study are: (1) to compare match load demands through load indicators between starters and substitutes, and (2) analyze the degree of correlation in the variables analyzed in this investigation. ...
Rigidified Bis(sulfonyl)ethylenes as Effective Michael Acceptors for Asymmetric Catalysis: Application to the Enantioselective Synthesis of Quaternary Hydantoins
(ACS, 2023-01-11)
The catalytic, enantio- and diastereoselective addition of
hydantoin surrogates II to “rigidified” vinylidene bis(sulfone) reagents is
developed, thus overcoming the inability of commonly employed β-
substituted vinylic ...
Brønsted Base-Catalyzed Enantioselective α-Functionalization of Carbonyl Compounds Involving π-Extended Enolates
(Wiley, 2023-11)
Chiral Brønsted base (BB) catalyzed asymmetric transformations constitute an important tool for synthesis. A meaningful fraction of these transformations proceeds through transiently generated enolate intermediates, which ...
Catalytic Asymmetric α-Functionalization of α-Branched Aldehydes
(MDPI, 2023-03-16)
Aldehydes constitute a main class of organic compounds widely applied in synthesis. As such, catalyst-controlled enantioselective α-functionalization of aldehydes has attracted great interest over the years. In this context, ...
Reducing Negative Aging Stereotypes via Educational Intervention in Older People: A Randomized Controlled Study
(Sage, 2022-09-13)
Anti-ageism interventions traditionally target younger individuals. We analyzed the effect of an educational intervention that combined an infusion of aging content with videos to reduce negative stereotypes toward aging ...
