We present a variation of a method of classification based in uncertainty on credal set. Similarly to its origin it use the imprecise Dirichlet model to create the credal set and the same uncertainty measures. It take into account sets of two variables to reduce the uncertainty and to seek the direct relations between the variables in the data base and the variable to be classified. The success...

We evaluate the influence of demographic, socioeconomic, and maternal variables on the nutritional status of adolescents aged 11 years. We conducted a prospective cohort study including 4,452 adolescents born in Pelotas, Southern Brazil, in 1993, accounting for 87.5% of the original cohort. Nutritional status was evaluated based on World Health Organization criteria. Subjects were classified ac...

the genus onobrychis is an important forage crop consisting of approximately 130 annual and perennial species. in this study, 13 populations of five onobrychis species were analyzed. the basic chromosome number varied from x=7 to x=8. according to stebbins’ classification, populations such as o. aucheri subsp. psammophila, o. crista-galli (1) and o. crista-galli (2) were classified in symmetric...

in order to evaluate the effects of forest road on regeneration and vegetation composition in district no. 2 shafaroud, a road was selected with the length of 400 m that the altitude, aspect, slope variations and species composition were similar. five transects in right and 5 transects in left side of road, were established as perpendicular. in each transect 5, 15, 25 and 35 m distances were de...

REDD (Reduced Emissions from Deforestation and forest Degradation) constitutes a set of financial incentives designed to reduce CO2 emissions from forest degradation and deforestation. REDD success depends on measuring forest biomass as a proxy for CO2 stocks. We tested the efficacy of airborne Xand P-band interferometry as a remote-sensing method to quantify forest biomass and detect changes i...

BACKGROUND Although malaria rapid diagnostic tests (RDTs) have been extensively evaluated since their introduction in the early 1990's, sensitivity and specificity vary widely limiting successful integration into clinical practice. This paper reviews specific issues surrounding RDT use in field settings and presents results of research investigating how to interpret "faint test bands" on ParaCh...

M e t h o d s Design: 2 cohort studies, 1 for derivation and 1 for validation (Acute Decompensated Heart Failure National Registry [ADHERE]). Setting: 263 centers in the United States. Patients: Patients in the ADHERE registry were ≥ 18 years of age and had new-onset ADHF or decompensation of chronic HF with symptoms severe enough to require hospitalization. 33 046 hospitalizations (mean age 73...

OBJECTIVE To understand phenotypic and molecular characteristics of patients with clinically "definite" primary lateral sclerosis (PLS) in a prospective study. METHODS Six sites enrolled 41 patients who had pure upper motor neuron dysfunction, bulbar symptoms, a normal EMG done within 12 months of enrollment, and onset of symptoms ≥5 years before enrollment. For phenotypic analyses, 27 demogr...
