1. Validation of the Portuguese version of the Community Assessment of Psychic Experiences and characterization of psychotic experiences in a Brazilian sample
Objective: We investigated: i) the reliability and validity of a Brazilian version of the Community Assessment of Psychic Experiences (CAPE), developed to detect and characterize psychotic experiences in the general population; and ii) the association between psychotic experiences, childhood adversity, and cannabis use in a population-based sample. Methods

2. RNA editing in the chloroplast of Asian Palmyra palm (Borassus flabellifer)
Abstract We have identified 46 RNA editing sites located in 20 chloroplast (cp) genes of Borassus flabellifer (Asian Palmyra palm), family Arecaceae, and tested these genes for supporting phylogenetic study among the commelinids. Among the 46 sites, 43 sites were found to cause amino acid alterations, which were predicted to increase the hydrophobicity and t

3. Selecting “the best” nonstationary Generalized Extreme Value (GEV) distribution: on the influence of different numbers of GEV-models
ABSTRACT The selection of an appropriate nonstationary Generalized Extreme Value (GEV) distribution is frequently based on methods, such as Akaike information criterion (AIC), second-order Akaike information criterion (AICc), Bayesian information criterion (BIC) and likelihood ratio test (LRT). Since these methods compare all GEV-models considered within a s

4. Evolutionary study of potentially zoonotic hepatitis E virus genotype 3 from swine in Northeast Brazil
Hepatitis E virus (HEV), an emerging virus associated with acute hepatic disease, leads to thousands of deaths worldwide. HEV has already been reported in Brazil; however, there is a lack of epidemiological and molecular information on the genetic variability, taxonomy, and evolution of HEV. It is thus unclear whether hepatitis E is a neglected disease in Br

5. Nota sobre o sistema de parentesco em Proto-Tupí-Guaraní
Resumo Este estudo explora o sistema de terminologia de parentesco da língua Proto-Tupí-Guaraní (PTG) a partir de uma perspectiva interdisciplinar, que soma contribuições da Etnologia, da Linguística Histórica e dos trabalhos etnográficos realizados com povos Tupí-Guaraní. Fazem-se inferências sobre pré-história cultural utilizando métodos filo

6. THEORY OF UNPLEASANT SYMPTOMS: CRITICAL ANALYSIS
RESUMO Objetivo: analisar a Teoria dos Sintomas Desagradáveis de acordo com o modelo proposto por Walker e Avant. Método: estudo de natureza descritivo-reflexiva, desenvolvido no primeiro semestre de 2016. Utilizou as cinco primeiras fases propostas pelo modelo de Walker e Avant: identificação das origens da teoria; exame do significado da teoria; adeq

7. Modeling and mapping basal area of Pinus taeda L. plantation using airborne LiDAR data
ABSTRACT Basal area (BA) is a good predictor of timber stand volume and forest growth. This study developed predictive models using field and airborne LiDAR (Light Detection and Ranging) data for estimation of basal area in Pinus taeda plantation in south Brazil. In the field, BA was collected from conventional forest inventory plots. Multiple linear regress

8. Reassessment and Relationships of †Scutatuspinosus itapagipensis (Teleostei, Clupeomorpha, †Ellimmichthyiformes) from the Neocomian of Recôncavo Basin, Northeastern Brazil
ABSTRACT Clupeomorphs are found in many assemblages of the northeastern Brazil, whose ages range from the Neocomian to Paleogene. Ten species were described. Among them †Scutatuspinosus itapagipensis, a torpedo-like fish found in shales of the Marfim Formation from Bahia, remains poorly known. At first it was positioned within †Scutatuspinosinae and indi

9. SELECTING PROFILES OF IN DEBT CLIENTS OF A BRAZILIAN TELEPHONE COMPANY: NEW LASSO AND ADAPTIVE LASSO ALGORITHMS IN THE COX MODEL
Variable selection plays an important rule in identifying possible factors that could predict the behavior of clients with respect to the bill payments. The Cox model is the standard approach for modeling the time until starting the lack of payments. Parsimony and capacity of predicting are some desirable characteristics of statistical models. This paper aim

10. Conservation of mayflies (Insecta, Ephemeroptera) in Espírito Santo, southeastern Brazil
Conservation of mayflies (Insecta, Ephemeroptera) in Espírito Santo, southeastern Brazil. Ephemeroptera exhibits great diversity among bodies of freshwater in the Atlantic Forest, a biome that is suffering from massive human impact. Within this context, the creation of conservation units using biological information is more recommended than economic, cultur

11. Large-scale analysis of NBS domain-encoding resistance gene analogs in Triticeae
Proteins containing nucleotide binding sites (NBS) encoded by plant resistance genes play an important role in the response of plants to a wide array of pathogens. In this paper, an in silico search was conducted in order to identify and characterize members of NBS-encoding gene family in the tribe of Triticeae. A final dataset of 199 sequences was obtained

12. Hybrid GRASP heuristics for the phylogeny problem combining path-relinking and genetic algorithm as an intensification strategy
A phylogeny is a tree that relates taxonomic units based on their similarity over a set of characteristics. The phylogeny problem under the parsimony criterion consists in finding a phylogeny with a minimum number of evolutionary steps. We propose hybrid heuristic methods - based on GRASP, path-relinking and genetic algorithm methodologies - to build a phylo
