1. Simulating the behavior of patients who leave a public hospital emergency department without being seen by a physician: a cellular automaton and agent-based framework
The objective of this study was to develop an agent based modeling (ABM) framework to simulate the behavior of patients who leave a public hospital emergency department (ED) without being seen (LWBS). In doing so, the study complements computer modeling and cellular automata (CA) techniques to simulate the behavior of patients in an ED. After verifying and v

4. Proposing the novelty classifier for face recognition
INTRODUCTION: Face recognition, one of the most explored themes in biometry, is used in a wide range of applications: access control, forensic detection, surveillance and monitoring systems, and robotic and human machine interactions. In this paper, a new classifier is proposed for face recognition: the novelty classifier. METHODS: The performance of a novel

6. Sobrevivência, morfo-anatomia, crescimento e assimilação de carbono de seis espécies arbóreas neotropicais submetidas à saturação hídrica do solo / Survival, morpho-anatomy, growth and carbon assimilation of six neotropical tree species submitted to flooding
Alchornea triplinervia, Nectandra oppositifolia, Eugenia umbelliflora, Gomidesia schaueriana, Guapira opposita and Guatteria gomeziana are typical tree species of swampy areas of Restinga Forest in Southeastern Brazil. To elucidate effects of seasonal flooding on survival, morpho-anatomy, growth and carbon assimilation rate in these species, were evaluated g

7. Intrauterine growth restriction in an experimental model of pregnant rats and their effects on insulin cellular receptors / Modelo experimental de restrição de crescimento intrauterino em ratas prenhes e suas repercussões em receptores celulares de insulina
Intrauterine growth restriction (IUGR) limits appropriate fetal development increasing morbidity and perinatal mortality. Adaptive mechanisms in fetal IUGR may leave to endocrine and metabolic alterations that could explain the occurrence of diseases in adulthood. The aim of this study was to evaluate whether experimental IUGR by uterine artery ligation caus

10. Alocação dinâmica de recursos computacionais para experimentos científicos com replanejamento automatizado a bordo de satélites / Dybanic allocation of computational resources for scientific experiments with autonomous replanning aboards satellites
The experiments aboard the Brazilian scientific satellites are currently thought to execute its tasks in a repetitive way, collecting, storing and sending data in a cycle that does not suffer great alterations. This way of dealing with the experiments operation fits perfectly to long-term scientific observation. There are, however, short-duration scientific

11. Ecologia do bicudo-do-algodoeiro Anthonomus grandis Boheman, 1843 (Coleoptera:Curculionidae) no Cerrado do Brasil Central
The boll weevil Anthonomus grandis Boheman, 1843 (Coleoptera: Curculionidae), one of the main pests of cotton, was introduced in Brazil in 1983. It causes the most serious damage to the crop, such as the falling of the flower buds, destruction of bolls and reduced linter production. The serious pest status of the boll weevil is mainly due to its high reprodu

12. Evaluation of gene selection metrics for tumor cell classification
Gene expression profiles contain the expression level of thousands of genes. Depending on the issue under investigation, this large amount of data makes analysis impractical. Thus, it is important to select subsets of relevant genes to work with. This paper investigates different metrics for gene selection. The metrics are evaluated based on their ability in
