Development of an absolute method for efficiency calibration of a coaxial HPGe detector for large volume sources
(Elsevier, 2015)
In this work an absolute method for the determination of the full energy peak efficiency of a gamma spectroscopy system for voluminous sources is presented. The method was tested for a high-resolution coaxial HPGe detector ...
SVR-FFS: A novel forward feature selection approach for high-frequency time series forecasting using support vector regression
(Elsevier, 2020)
n this paper, we propose a novel support vector regression (SVR) approach for time series analysis. An efficient forward feature selection strategy has been designed for dealing with high-frequency time series with multiple ...
Acanthosis nigricans as an indicator of insulin resistance in Chilean adult population Acantosis nigricans como un indicador deinsulinoresistencia en poblacion Chilena adulta
(2011)
Background: Insulin resistance (IR) is associated with a higher risk of multiple diseases and its early detection would allow to minimize the associated risk; the presence of acanthosis nigricans (AN) it's associated to ...
A new PCR-RFLP for species-specific diagnosis of South American animal trypanosomiasis
(2014)
The diagnosis of animal trypanosomiasis in field samples is currently based on clinical suspicion and less
frequently on traditional parasitological methods characterized by their very low sensitivity, especially in the ...
Partial molar volume of anionic polyelectrolytes in aqueous solution
(2007)
In this work the partial molar volumes (V) of different anionic polyelectrolytes and hydrophobically modified polyelectrolytes (PHM) were measured. Polymers like polymaleic acid-co-styrene, polymaleic acid-co-1-olefin, ...
Interaction between anionic polyelectrolytes and CTAB micelles. A potentiometric study
(2004)
The interaction between a series of anionic copolymers having variable hydrophobic character with cationic micelles of cetyltrimethylammonium bromide (CTAB) has been studied by measuring the free bromide ion concentration. ...
Specificity evolution of the ADP-dependent sugar kinase family: in silico studies of the glucokinase/phosphofructokinase bifunctional enzyme from Methanocaldococcus jannaschii.
(Federation of European Biochemical Societies, Blackwell Publishing Ltd, 2008-07-10)
In several archaea of the Euryarchaeota, the glycolytic flux proceeds through a modified version of the Embden-Meyerhof pathway, where the phosphofructokinase and glucokinase enzymes use ADP as the phosphoryl donor. These ...
High prevalence of specific language impairment in Robinson Crusoe Island. A possible founder effect Alta prevalencia de trastorno específico de lenguaje en isla Robinson Crusoe y probable efecto fundador
(2008)
Background: Specific language impairment (SLI) occurs in 2% to 8% of preschool children. Major and candidate genes are probably involved. Genetic drift is a cause for the presence of high frequencies of deleterious alleles ...
DMAKit: A user-friendly web platform for bringing state-of-the-art data analysis techniques to non-specific users
(Elsevier, 2020)
Tremendous advances in different areas of knowledge are producing vast volumes of data, a quantity
so large that it has made necessary the development of new computational algorithms. Among the
algorithms developed, we ...
Molecular characterization of hospital-acquired adenovirus infantile respiratory infection in Chile using species-specific PCR assays
(2007)
Background: Adenovirus serotypes 7, 2 and 1 are the second most common cause of viral acute lower respiratory tract infection (ALRI) requiring hospitalization in Chile. Nosocomial outbreaks have high secondary attack and ...
