1. Caracterização da fertilidade do solo, distribuição do sistema radicular e índice de qualidade do solo no Ecossistema Restinga do Litoral Paulista
A Restinga é um conjunto de comunidades vegetais em mosaico, determinadas pelas características de seus substratos resultantes de processos deposicionais e idades. De todos os ecossistemas associados à Mata Atlântica, a restinga é a mais frágil e susceptível às perturbações antrópicas. Neste complexo mosaico encontram-se as fitofisionomias de flor

2. Trends and predictors of changes in pulmonary function after treatment for pulmonary tuberculosis
OBJECTIVES: The present study aimed to investigate the trends in changes in pulmonary function and the risk factors for pulmonary function deterioration in patients with pulmonary tuberculosis after completing treatment. INTRODUCTION: Patients usually have pulmonary function abnormalities after completing treatment for pulmonary tuberculosis. The time course

3. RADIOLOCALIZAÇÃO DE TERMINAIS DE COMUNICAÇÕES MÓVEIS / RADIOLOCATION OF MOBILE COMMUNICATIONS TERMINALS
This work addresses the radiolocation problem of a moving terminal in a cellular mobile communications environment. New alternatives are developed for position estimation, assuming that the Time of Arrival (ToA) measurements obtained from radio link are corrupted by additive noise and have positive mean error during random periods of time due to the non-line

4. Pulmonary function in asbestos cement workers: a dose-response study.
This study has found that residence time weighted exposure (asbestos dose) may be used to model the risk and extent of pulmonary function abnormalities in a cohort of asbestos cement workers. This parameter, which incorporates both exposure concentration and latency, had previously proved useful for modelling the risk of radiographic abnormalities in this co

5. Genetic Models for the Analysis of Data from the Families of Identical Twins
Genetic models are described which exploit the unique relationships that exist within the families of identical twins to obtain weighted least squares estimates of additive, dominance and epistatic components of genetic variance as well as estimates of the contributions of X-linked genes, maternal effects and three sources of environmental variation. Since a

6. Weighted Feature Significance: A Simple, Interpretable Model of Compound Toxicity Based on the Statistical Enrichment of Structural Features
In support of the U.S. Tox21 program, we have developed a simple and chemically intuitive model we call weighted feature significance (WFS) to predict the toxicological activity of compounds, based on the statistical enrichment of structural features in toxic compounds. We trained and tested the model on the following: (1) data from quantitative high–throu

7. Geographical Variation in a Quantitative Character
A model for the evolution of the local averages of a quantitative character under migration, selection, and random genetic drift in a subdivided population is formulated and investigated. Generations are discrete and nonoverlapping; the monoecious, diploid population mates at random in each deme. All three evolutionary forces are weak, but the migration patt

8. Type 2 diabetes: Evidence for linkage on chromosome 20 in 716 Finnish affected sib pairs
We are conducting a genome scan at an average resolution of 10 centimorgans (cM) for type 2 diabetes susceptibility genes in 716 affected sib pairs from 477 Finnish families. To date, our best evidence for linkage is on chromosome 20 with potentially separable peaks located on both the long and short arms. The unweighted multipoint maximum logarithm of odds

9. Genetic and Statistical Analyses of Strong Selection on Polygenic Traits: What, Me Normal?
We develop a general population genetic framework for analyzing selection on many loci, and apply it to strong truncation and disruptive selection on an additive polygenic trait. We first present statistical methods for analyzing the infinitesimal model, in which offspring breeding values are normally distributed around the mean of the parents, with fixed va

10. Interacting Genetic Loci on Chromosomes 20 and 10 Influence Extreme Human Obesity
Obesity is a multigenic trait that has a substantial genetic component. Animal models confirm a role for gene-gene interactions, and human studies suggest that as much as one-third of the heritable variance may be due to nonadditive gene effects. To evaluate potential epistatic interactions among five regions, on chromosomes 7, 10, and 20, that have previous
