1. ECG Signals Classification Using Overlapping Variables to Detect Atrial Fibrillation
ABSTRACT In the present work a method for the detection of the cardiac pathology known as atrial fibrillation is proposed by calculating different information, statistics and other nonlinear measures over ECG signals. The original database contains records corresponding to patients who are diagnosed with this disease as well as healthy subjects. To formulate

2. Extracorporeal Membrane Oxygenation (ECMO) Training Program in A Pediatric Cardiac Intensive Care Unit: An 8-Year Single-Center Experience in Argentina
ABSTRACT Introduction: Extracorporeal membrane oxygenation (ECMO) for temporary cardiopulmonary support is one of the most intense and technologically complex therapies offered in medicine. It is a high-risk procedure that requires specific knowledge and technical skills to perform it with good results. Objective: The main goal of this study is to describe

3. PREPARAÇÃO E VALIDAÇÃO DE ARQUIVOS DE ENTRADA PARA USO NO SIMULADOR DE QUALIDADE DO AR (CMAQ)
According to the inventories carried out by the air pollution control agencies, vehicle emissions are responsible for more than 70% of air pollutants in metropolitan regions. Proper handling of CMAQ input data is an important step in the formation of a database for the model. Thus, it is necessary to insert the meteorological data using the Weather Research

5. International VaR approach: Backtesting for different capital markets
RESUMO O objetivo deste artigo é comparar diferentes métricas de valor em risco (VaR), distinguindo-se de estudos anteriores na medida em que compara três categorias de ativos pertencentes a sete países. Desde a concepção do VaR, foram desenvolvidas várias abordagens para melhorar a precisão da estimativa de perdas. Entretanto, praticamente inexiste

6. ROBUST METHODOLOGY FOR DETECTION OF SPIKES IN MULTIBEAM ECHO SOUNDER DATA
Abstract Currently, during the operation in shallow waters, scanning systems, such as multibeam systems, are capable of collecting thousands of points in a short time, promoting a greater coverage of the submerged bottom, with consequent increase in the detection capacity of objects. Although there has been an improvement in the accuracy of the depths collec

7. New insights into genomic selection through population-based non-parametric prediction methods
ABSTRACT: Genome-wide selection (GWS) is based on a large number of markers widely distributed throughout the genome. Genome-wide selection provides for the estimation of the effect of each molecular marker on the phenotype, thereby allowing for the capture of all genes affecting the quantitative traits of interest. The main statistical tools applied to GWS

8. Avaliação de Parametrizações de Camada Limite Planetária do Modelo WRF na Costa Norte do Nordeste do Brasil
Resumo Este trabalho tem como objetivo avaliar duas simulações do modelo WRF que diferem em sua parametrização da Camada Limite Planetária (CLP). Foram utilizados dados de 72 radiossondas lançadas em Fortaleza (CE) entre 5 e 25 de Abril de 2011 nos horários sinóticos. A altura da CLP foi a variável avaliada e os valores observados, calculados pelo m

9. O Internato Médico após as Diretrizes Curriculares Nacionais de 2014: um Estudo em Escolas Médicas do Estado do Rio de Janeiro
RESUMO Instituídas em 2014, as Diretrizes Curriculares Nacionais (DCN) do Curso de Graduação em Medicina contêm várias recomendações, especialmente para o internato médico. Apesar do reconhecimento da necessidade de mudanças no que se refere à capacitação profissional para atender às demandas da comunidade, muitos consideraram pouco democrática

10. MODELOS FOTOQUÍMICOS SIMPLES COMO FERRAMENTA PARA O GERENCIAMENTO DA QUALIDADE DO AR
Atmospheric processes in an urban scenario are very complex and depend on meteorological parameters, emission, transport and deposition processes and the chemical mechanism. Simple air quality models can be used to understand the main aspects of ozone formation and provide information to adopt pollution control strategies. In this work the detailed simulatio

11. Diseño y Evaluación de una Trayectoria Hipotética de Aprendizaje para Intervalos de Confianza basada en Simulación y Datos Reales
Abstract This article discusses the design of a hypothetical learning trajectory to introduce the confidence intervals in a basic university course, from an informal perspective based on the use of data obtained from surveys and samples simulation. The trajectory consists of four activities and was evaluated as part of a first improvement cycle with a group

12. Rbio: A tool for biometric and statistical analysis using the R platform
Abstract Rbio is a free software for data processing. It is compatible and integrated with the free R software, which is globally accepted for statistical analysis. Thus, Rbio takes advantage of all processing potential of the R software. However, this new software allows the user to perform all the analyses without knowing the programming in R language. Rbi
