The preparation, magnetic characterization and antimicrobial properties of the complexes [Fe3O(CH3COO)(6)(CH3COOH)(H2O)]Cl(Melmid)center dot(H2O) (1) and [Fe4O2 (CH3COO)(7)O-2(BPA)(2)(H2O)]center dot Cl center dot ...
Evaluation of intramolecular energy transfer process in the lanthanide(III) bis- and tris-(TTA) complexes: Photoluminescent and triboluminescent behavior
(Elsevier Science BvAmsterdamHolanda, 2008)
Multichannel Time-Frequency Complexity Measures for the Analysis of Age-Related Changes in Neuromagnetic Resting-State Activity
(Instituto de Ingeniería Eléctrica y Electrónica, 2019-01)
We propose new multichannel time-frequency complexity measures to evaluate differences on magnetoencephalograpy (MEG) recordings between healthy young and old subjects at rest at different spatial scales. After reviewing ...
Inclusion complex of 4-hydroxycoumarin with cyclodextrins and its characterization in aqueous solution
(2011)
The physicochemical properties of 4-hydroxy-7-methoxy-3-phenyl-2H-chromen- 2-one (4HC) and β-cyclodextrins (CDs) inclusion complexes were investigated. The phase solubility profile of 4HC with β-cyclodextrin derivatives ...
Empirical correlations involving calorimetric, thermogravimetric and infrared data for zinc halides adducts
(Pergamon-elsevier Science LtdOxfordInglaterra, 2002)
Sprayed films of europium complexes toward light conversion devices
(Elsevier B.V., 2014-09-01)
Rare-earth complexes have become subject of intensive research due to the high quantum efficiency of their emission, very narrow bands, and excellent fluorescence monochromaticity. The chemical design and characterization ...
A study of the use of complexity measures in the similarity search process adopted by kNN algorithm for time series prediction
(Institute of Electrical and Electronics Engineers - IEEEMiami, 2015-12)
In the last two decades, with the rise of the Data Mining process, there is an increasing interest in the adaptation of Machine Learning methods to support Time Series non-parametric modeling and prediction. The non-parametric ...
The complexation of marine and terrestrial organic materials with copper (II) ions as determined by fluorescence quenching
(Science & Technology LettersNorthwoodInglaterra, 1997)
Synthesis, spectroscopic characterization, structural studies, and In Vitro antitumor activities of Pyridine-3-carbaldehyde Thiosemicarbazone derivatives
(Hindawi, 2020)
Eight new thiosemicarbazone derivatives, 6-(1-trifluoroethoxy)pyridine-3-carbaldehyde thiosemicarbazone (1), 6-(4 '-fluorophenyl)pyridine-3-carbaldehyde thiosemicarbazone (2), 5-chloro-pyridine-3-carbaldehyde thiosemicarbazone ...
Magnitude modelling of HRTF using principal component analysis applied to complex values
(2014)
Principal components analysis (PCA) is frequently used for modelling the magnitude of the head related transfer functions (HRTFs). Assuming that the HRTFs are minimum phase systems, the phase is obtained from the Hilbert ...
