F region plasma density estimation at Jicamarca using the complex cross‐correlation of orthogonal polarized backscatter fields
(American Geophysical Union, 2004-06-16)
The differential‐phase method for Jicamarca F region density measurements has been modified to fit the real and imaginary components of the cross‐correlation of orthogonally polarized radar returns. The original method ...
Evolution of multifractal cross-correlations between the Argentina MERVAL Index and international commodities prices
(Routledge Journals, Taylor & Francis Ltd, 2016-10)
We compute the auto-correlations and cross-correlations of the volatility time series of the Argentina MERVAL Index (the Buenos Aires Stock Exchange main index) and three agricultural commodities, in a multifractal context ...
Analysis of the nonlinear relationship between commodity prices in the last two decades
(Springer, 2014-10)
We propose the construction of a network to study the correlation among price indices of different commodities, by using the Multifractal Cross-Correlation method proposed by Podobnik and Stanley. This estimator, based on ...

Single-stranded nucleic acids promote SAMHD1 complex formation
(Springer, 2013-06)
SAM domain and HD domain-containing protein 1 (SAMHD1) is a dGTP-dependent triphosphohydrolase that degrades deoxyribonucleoside triphosphates (dNTPs) thereby limiting the intracellular dNTP pool. Mutations in SAMHD1 ...
Validação e normatização do índice de complexidade da farmacoterapia para idosos atendidos na atenção primária à saúde
(Universidade Federal de Minas GeraisUFMG, 2017-06-30)
Regimen complexity has been associated with negative outcomes, such as hospitalization and non-adherence. Complex regimens are common among the elderly due to the high prevalence of comorbidities and the use of multiple ...
Corrigendum to Characterization of westward propagating signals in the South Atlantic from altimeter and radiometer records ”[Remote Sens. Environ., 134: 367-376]
(New York, 2013-04-12)
Radar altimeter data from TOPEX/Poseidon and Jason-1 and microwave radiometer data from TRMM/TMI are used to investigate the large-scale variability between 10.5°S and 35.5°S in the South Atlantic Ocean. The proposed method ...
