1. Bayesian modeling of the maximum streamflows from the Furnas reservoir
ABSTRACT The objective of this work was to predict the maximum flow of the Furnas reservoir in the dry and wet periods. The generalized distribution of extreme values (GEV) was used with parameter estimation via Bayesian inference. Data on average daily streamflows corresponding to the years 1965 to 2017 were obtained from Hidroweb, by the National Agency fo

2. Association of FOXO3 polymorphism (rs3800231) and clinical subphenotypes of beta thalassemic individuals
Abstract Introduction Studies have shown that the loss of the FOXO3 transcriptional function is involved in the pathophysiology of some chronic erythroid disorders, including beta-thalassemia (β-thal). Therefore, the single nucleotide polymorphism (SNP) rs3800231 (35-2764A > G) could contribute to alterations in its transcriptional activity, acting as a mo

3. The role of topographic-derived hydrological variables in explaining plant species distributions in Amazonia
RESUMO Nas florestas de terra firme não inundáveis da Amazônia, a composição florística e a ocorrência de espécies podem ser explicadas pela disponibilidade hídrica relacionada com a topografia. Dada a complexidade topográfica, a disponibilidade de água pode ser bastante variável e seus efeitos na resposta das plantas, difícil de documentar. Nes

4. A Novel In Silico Monte Carlo Approach to Optimize a PSD Estimation Problem. Generation of Data Fusion Experiment Rules
ABSTRACT This article analyzes the performance of combining information from Scanning Electron Microscopy (SEM) micrographs with Static Light Scattering (SLS) measurements for retrieving the so-called Particle Size Distribution (PSD) in terms of experimental features. The corresponding data fusion is implemented using a novel Monte Carlo-based method consist

5. On the classification and treatment of outliers in a spatial context: A Bayesian Updating approach
Abstract Checking and treating extreme values is commonplace in modelling workflows. The main methods to manage outliers may be categorized into graphical, Kriging- and simulation-based approaches. While graphical methods usually classify outliers from a global perspective, geostatistical methods evaluate outliers in a local context. Ordinary-Kriging based a

6. Geostatistical simulations with heterotopic hard and soft data without modeling the linear model of coregionalization
Abstract Most mining decisions are based on models estimated/simulated given the information obtained from samples. During the exploration stage, samples are commonly taken using diamond drill holes which are accurate and precise. These samples are considered hard data. In the production stage, new samples are added. These last are cheaper and more abundant

7. Influence of migration on the thought process of individuals at ultra-high risk for psychosis
Objective: To assess the influence of migration on the psychopathological presentation of individuals at ultra-high risk for psychosis (UHR) in São Paulo, Brazil. Methods: This study is part of the Subclinical Symptoms and Prodromal Psychosis (SSAPP) project, a cohort study in São Paulo, Brazil, designed to follow individuals at UHR. After screening with

8. Different scales determine the occurrence of aquatic macrophyte species in a tropical stream
ABSTRACT Distributions of aquatic macrophyte species are commonly associated with water chemistry characteristics. However, other environmental factors that can lead to the occurrence of aquatic plants in lotic ecosystems, such as dynamic habitats linked to the surrounding landscape, have been underestimated. This study aims to evaluate landscape features th

9. Orofacial characteristics of the very low-birth-weight preterm infants
Abstract Objective: To evaluate the orofacial characteristics of very low-birth-weight preterm infants through anthropometric facial measures, orofacial anteroposterior analysis and the relationship between the gum pads. Method: Orofacial examinations was performed in 154 infants, classified into two groups: Group A comprised 54 very low-birth-weight infan

10. SPATIAL VARIABILITY IN LEAF ANALYSIS AND PRODUCTIVITY OF FERTIRRIGATED AÇAÍ
ABSTRACT This study aimed to define management zones (MZs) for fertirrigated açaí cultivation, based on spatial variability of the foliar nutrients and productivity data. The work was carried out in an area of 5.75 ha of a 7-year crop, with 80 georeferenced sample points. Fresh fruit productivity and nutrient (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, and Zn) con

11. Novelties in Brazilian Waltheria L. (Byttnerioideae, Malvaceae): two new species and one re-establishment
ABSTRACT This work validates two Waltheria species endemic to campo rupestre with complete descriptions, illustrations, updated geographical distributions and comments on taxonomic affinities. Waltheria biribiriensis and Waltheria terminans are restricted to the Southern Espinhaço Province in eastern South America, occurring on mountain tops where campo rup

12. Response to commentary by Howard Waitzkin
ABSTRACT Genetic diversity studies are performed based on information on a set of traits measured in a group of genotypes, considering one or more environments. The pattern recognition methods allow classifying genotypes from a set of important agronomic information. Thus, this study aimed to present and compare pattern recognition methods to inquire about t
