1. Ring Fracture of Brazilian Aortic Valve Bioprostheses Using Non-Compliant High-Pressure Transcatheter Balloon, an Ex Vivo Test
ABSTRACT Introduction: Aortic valve bioprostheses ring fracture in valve-in-valve procedures has shown low complication rates and presents as an option in the treatment of patients at high risk for conventional surgery, avoiding high transvalvular gradients, which are associated with increased mortality. Some prostheses available in the market cannot be fra

2. Settlement of bored piles with expander body system in lateritic soils
Abstract The Expander Body pile (EB) is a combination of a cast-in-situ pile method with an inflated, pump-grouted tip. The EB system's pioneering conjunction with the conventional drilling pile technique has improved work load, foundation security, cost reductions and abrupt displacements in lateritic, porous, unsaturated soils. The aim of this article is t

3. Hospitalizations for cancer in international migrants versus local population in Chile
ABSTRACT OBJECTIVE To compare cancer hospital morbidity among the local population and the immigrant population in Chile. METHODS This is a prevalence study based on the analysis of hospital discharges of all the health centers of Chile. Cancer hospital discharges were characterized in 2012 according to the migratory status. The crude and specific rates

4. Modelos de regressão beta inflacionados truncados / The truncated inflated beta regression
Os modelos de regressão beta e beta inflacionados conseguem ajustar adequadamente grande parte das variáveis do tipo proporção. No entanto, esses modelos não são úteis quando a variável resposta não pode assumir valores no intervalo (0,c) e assume o valor c com probabilidade positiva. Variáveis relacionadas a algum tipo de pagamento limitado entre

5. Zero-inflated Poisson regression models for QTL mapping applied to tick-resistance in a Gyr x Holstein F2 population
Nowadays, an important and interesting alternative in the control of tick-infestation in cattle is to select resistant animals, and identify the respective quantitative trait loci (QTLs) and DNA markers, for posterior use in breeding programs. The number of ticks/animal is characterized as a discrete-counting trait, which could potentially follow Poisson dis

6. Distribuições em série de potências modificadas inflacionadas e distribuição Weibull binominal negativa / Inflated modified power serie distribution and Weibull negative binomial
In this paper, some result such as moments generating function, recurrence relations for moments and some theorems of the class of modified power series distributions (MPSD) proposed by Gupta (1974) and of the class of inflated modified power series distributions (IMPSD) both at a different point of zero as the zero point are presented. The standard Poisson

7. Verbal fluency in Alzheimer's disease, Parkinson's disease, and major depression
OBJECTIVE: To compare verbal fluency among Alzheimer's disease, Parkinson's disease, and major depression and to assess the sociodemographic and clinical factors associated with the disease severity. METHODS: Patients from an outpatient university center with a clinical diagnosis of Alzheimer's disease, Parkinson's disease or major depression were studied. S

8. Classe de distribuições série de potências inflacionadas com aplicações
Este trabalho tem como tema central a classe de distribuições série de potências inflacionadas, em que o intuito é estudar suas principais propriedades e a aplicabilidade no contexto bayesiano. Esta classe de modelos engloba as distribuições de Poisson, binomial e binomial negativa simples e as generalizadas e, por isso é muito aplicada na modelagem

9. Modelos estatísticos para mapeamento de QTL associados a dados de contagem / Statistical models for QTL mapping associated to counting data
This study has as main objective to analyze and compare statistical approaches to QTL mapping for parasites resistance in bovines. The animals, under artificial infestation, were periodically evaluated by counting, as ticks count. These data are characterized as repeated measures and, usually, dont follow or partially follow the usual requirements for the an

10. Inference and diagnostic in zero-inflated count data models / Inferencia e diagnostico em modelos para dados de contagem com excesso de zeros
Em análise de dados, muitas vezes encontramos dados de contagem onde a quantidade de zeros excede aquela esperada sob uma determinada distribuição, tal que não é possível fazer uso dos modelos de regressão usuais. Além disso, o excesso de zeros pode fazer com que exista sobredispersão nos dados. Neste trabalho são apresentados quatro tipos de model

11. Inflated beta regression models / Modelos de regressão beta inflacionados
The last years have seen new developments in the theory of beta regression models, which are useful for modelling random variables that assume values in the standard unit interval such as proportions, rates and fractions. In many situations, the dependent variable contains zeros and/or ones. In such cases, continuous distributions are not suitable for modeli

12. VitimizaÃÃo e desigualdade de renda no Brasil / Victimization and inaquality of income in Brazil
The violence and criminality have become a constant problem for all the population. Ahead of this scene, literature on the economy of the crime has expanded quickly, being focused principally in the relation between the indicators of economical inequality and the distribution of the crimes between the regions, besides checking which social and economic chara
