1. Efficient Low-Complexity Optimized Channel Estimating Methods for OFDM-Based Low-Voltage Broadband Power Line Communication Systems
Abstract Broadband Power Line Communication (BB-PLC) technology enables data transmission for smart grid applications. Nevertheless, channel equalizers are required in the receiver to estimate and compensate for the nonlinear time-variant impulse response and noise interference effects introduced by the BB-PLC channel. In this paper, we append the Particle S

2. Pediatric population with cystic fibrosis in the centre of Portugal: candidates for new therapies
Abstract Objectives: Cystic fibrosis (CF) is a severe autosomal recessive disease that results from mutations in a gene encoding the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein, a chloride channel. This study aims to characterize the clinical and genetic features of a cohort of pediatric people with CF (PwCF) in the center of Portugal

3. Multi-Step-Ahead Spectrum Prediction for Cognitive Radio in Fading Scenarios
Abstract This paper analyzes multi-step-ahead spectrum prediction for Cognitive Radio (CR) systems using several future states. A slot-based scenario is used, and prediction is based on the Support Vector Machine (SVM) algorithm. The aim is to determine whether multi-step-ahead spectrum prediction has gains in terms of reduced channel-switching and increased

4. Vidas indestrutíveis: micropolíticas da pobreza na vida homossexual
Resumo Por meio das composições teóricas estabelecidas por Foucault sobre poder, tecnologia de poder e discurso, Guattari, Deleuze e Rolnik formularam uma nova perspectiva de articulação teórica ao perceberem que, em meio às relações privadas existem micropolíticas que se corporificam como forças normalizadoras dos comportamentos e desejos humanos

5. R&D spillovers from international student flows: a brics analysis
Abstract Paper aims to analyze the international flow of students - both from developed and underdeveloped countries - and to observe their significance for the productivity gains of the country of origin of these students. Originality The main contributions to the literature are the understanding of how student flows affect countries' economic growth, as

6. ANFITRIÕES: DELINEANDO O CONCEITO DE PÓS-HUMANO NA SÉRIE TELEVISIVA WESTWORLD
RESUMO O presente artigo parte da discussão sobre o pós-humano que vem crescendo ao longo dos últimos trinta anos, destacando especialmente a década de noventa quando pesquisadores do cenário internacional e nacional ampliaram o debate, a partir das hibridações entre o corpo e as inovações tecnológicas. Esta temática também vem sendo apresentada

7. Two-dimensional Boussinesq equations applied to channel flows: deducing and applying the equations
RESUMO Uma das hipóteses básicas adotada para a formulação teórica dos escoamentos de fluidos é a distribuição da pressão hidrostática na vertical. No entanto, muitos pesquisadores apontaram que essa simplificação pode levar a erros, em casos como o escoamento na ruptura de barragens. A discrepância entre a solução computacional e o experiment

8. Estimativa do coeficiente de transferência de massa de oxigênio com o uso da técnica das sondas solúveis flutuantes: um estudo de laboratório
RESUMO A sonda solúvel flutuante (SSF) é considerada uma técnica de baixo custo para a estimativa do coeficiente de transferência de massa de oxigênio na interface ar-água (KL). Essa técnica se baseia no fato que KL pode ser correlacionado com a velocidade de dissolução do sólido solúvel (VS), uma vez que ambos os parâmetros são influenciados pe

10. Synthesis and anti-myocarditis activity in a multifunctional lanthanide microporous metal-organic framework with 1D helical chain building units
A new microporous lanthanide metal-organic framework, {[Yb(BTB)(H2O) (DEF)2}n (1, DEF=N,N-Diethylformamide), with 1D nano-sized channels has been constructed by bridging helical chain secondary building units with 1,3,5-benzenetrisbenzoic acid (H3BTB) ligand. Structural characterization suggests that this complex crystallizes in the hexagonal space group P61

11. A Bayesian analysis of the parasitic ecology in Jenynsia multidentata(Pisces: Anablepidae)
ABSTRACT Jenynsia multidentata Jenyns, 1842 (one-sided livebearers) are euryhaline viviparous fish of small size, used in the laboratory experiment, important as resource for biological control of mosquito’s larva and a key species to recover eutrophic lakes. Works have been published dealing with parasite biodiversity of this host, but little has been stu

12. Tyrosine phosphorylation of Kv1.5 is upregulated in intrauterine growth retardation rats with exaggerated pulmonary hypertension
Intrauterine growth retardation (IUGR) is associated with the development of adult-onset diseases, including pulmonary hypertension. However, the underlying mechanism of the early nutritional insult that results in pulmonary vascular dysfunction later in life is not fully understood. Here, we investigated the role of tyrosine phosphorylation of voltage-gated
