1. Áreas agrícolas em sensores com resolução espacial de 30m estimadas a partir de dados originais e simulados MODIS e métricas de paisagem / Crop area in spatial resolution of 30m estimated with original and simulated MODIS data and landscape metrics
O agronegócio tem papel de destaque na economia brasileira. Dessa forma, a criação de metodologias para o monitoramento agrícola é fundamental. Nesta linha de raciocínio, a estimativa de área agrícola é uma atividade importante para a previsão de safras e avaliação da disponibilidade de produtos para abastecimento interno e exportações. A utili

2. Multidimensional robust control, uncertainty and finance / Multidimensional robust control, uncertainty and finance
Optimal control theory has being a source of useful tools (including Euler equations, ztransforms, lag operators, Bellman equations, Kalman filtering) to study dynamic economics problems. A more recent field of optimal control, namely robust control, has recently been adopted by some leading economists (Thomas Sargent, Lars Hansen and coauthors) to study imp

5. Group recommendation strategies based on collaborative filtering
Nowadays, the amount of information available far exceeds our ability to manage it. We can choose from dozens of TV channels, thousands of movies, millions of books, billions of on-line documents. When we have to make choices without full knowledge of the alternatives, a common approach is to rely on recommendations of trusted persons. In the 1990s computer

6. Quantitative quality control in microarray image processing and data acquisition
A new integrated image analysis package with quantitative quality control schemes is described for cDNA microarray technology. The package employs an iterative algorithm that utilizes both intensity characteristics and spatial information of the spots on a microarray image for signal–background segmentation and defines five quality scores for each spo

7. Quantifying Modularity in the Evolution of Biomolecular Systems
Functional modules are considered the primary building blocks of biomolecular systems. Here we study to what extent functional modules behave cohesively across genomes:That is, are functional modules also evolutionary modules? We probe this question by analyzing for a large collection of functional modules the phyletic patterns of their genes across 110 geno

8. Visual and clinical analysis of Bac-T-Screen urine screen results.
Of 337 urine specimens evaluated, 75 of the 113 that showed positive readings on the Bac-T-Screen urine-screening instrument were found by subsequent semiquantitative culture to yield either less than 10,000 CFU of mixed bacteria per ml or no growth (less than 100 CFU/ml by our criteria). We tried to determine what factors contributed to the positive Bac-T-S

9. Rates of Microbenthic and Meiobenthic Bacterivory in a Temperate Muddy Tidal Flat Community
Rates of bacterivory in micro- and meiobenthic species were determined by an improved technique in a muddy tidal flat community in Boston Harbor, Mass. The predominant grazers of bacteria were identified, and their rates of grazing were measured in the top 1 cm of the sediment. Grazing rates were measured by a fluorescence-labeled bacteria (FLB) technique. A

10. Development of a Test System To Evaluate Procedures for Decontamination of Respirators Containing Viral Droplets▿
The aim of this study was to develop a test system to evaluate the effectiveness of procedures for decontamination of respirators contaminated with viral droplets. MS2 coliphage was used as a surrogate for pathogenic viruses. A viral droplet test system was constructed, and the size distribution of viral droplets loaded directly onto respirators was characte

11. The inhibition of single N-methyl-D-aspartate-activated channels by zinc ions on cultured rat neurones.
1. Single channels activated by N-methyl-D-aspartate (NMDA) were studied in outside-out patches of cultured hippocampal neurones in the presence of glycine and absence of magnesium. The effects of the transition metal ions zinc and cadmium on NMDA channels were tested by placing the membrane patch at the mouth of one of an array of large barrelled flow pipes
