Pinças ópticas: experimento, teoria e aplicação no estudo da interação DNA-fármacos
(Universidade Federal de Minas GeraisUFMG, 2008-03-19)
We started this work studying the physics of optical tweezers. This isa micromanipulation technique much used to study particles and biological systems with size in the micrometer range. We theoretically analyze the ...
Viés e lacunas de coleta na biota do Oceano Atlântico Ocidental
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE ZOOLOGIAPrograma de Pós-Graduação em ZoologiaUFMG, 2021-05-31)
The Atlantic Ocean biota has sampling gaps that are a consequence of the collection bias. Understanding which factors contribute to the collection bias is important for estimating biodiversity indicators. The present study ...
Comparação de estratégias de geração de propostas no algoritmo Metropolis-Hastings para um modelo Poisson log-linear
(Universidade Federal de Minas GeraisUFMG, 2016-02-26)
The Markov Chain Monte Carlo methods (MCMC) are a class of simulation algorithms widely used in Bayesian inference to indirectly draw samples from the posterior distribution, which is known up to a constant of proportionality. ...
Aplicação digital twin para auxílio de detecção de anomalias no consumo de gás
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE ESTATÍSTICAPrograma de Pós-Graduação em EstatísticaUFMG, 2021-06-02)
Gas or energy distribution companies must always pay attention to the gas or energy meters in order to ensure that they are charging for the product correctly, that is, that they are receiving for the correct amount of ...
Estudo da transição entrópica do DNA induzida por intercalantes utilizando a técnica de Pinçamento Óptico e Espectroscopia de autocorrelação de intensidades
(Universidade Federal de Minas GeraisUFMG, 2007-11-05)
At the present work measurements of persistence and contour length of DNA drug complexes were performed. The effects of two drugs that intercalates DNA molecule were studied: daunomycin and ethidium bromide. A systematic ...
Underlying dynamics of typical fluctuations of an emerging market price index: the Heston model from minutes to months
(Elsevier B.V., 2006-02-15)
We investigate the Heston model with stochastic volatility and exponential tails as a model for the typical price fluctuations of the Brazilian São Paulo Stock Exchange Index (IBOVESPA). Raw prices are first corrected for ...
Honey Ants (Genus Myrmecocystus) Macroecology: Effect of Spatial Patterns on the Relationship between Worker Body Size and Geographic Range Size
(1998-10-01)
Macroecology evaluates the partitioning of physical space and resources among organisms through correlation among ecological variables, such as geographical range size and shape, body size, and population density, measured ...
Geographic variation of Africanized honey bees (Apis mellifera L.) in Brazil: Multivariate morphometrics and racial admixture
(1996-06-01)
The correspondence between morphometric and isozymic geographic variation patterns of Africanized honey bees in Brazil was analyzed. Morphometric data consisted of mean vectors of 19 wing traits measured in 42 local ...
Assessing the significance of the correlation between the components of a bivariate Gaussian random field
(John Wiley and Sons Ltd, 2015)
Assessing the significance of the correlation between the components of a bivariate random field is of great interest in the analysis of spatial data. This problem has been addressed in the literature using suitable ...
