Human Adipose‐Derived Mesenchymal Stem Cells Cryopreservation and Thawing Decrease α4‐Integrin Expression

open access: yesStem Cells International, Volume 2016, Issue 1, 2016., 2016
Aim. The effects of cryopreservation on adipose tissue‐derived mesenchymal stem cells are not clearly documented, as there is a growing body of evidence about the importance of adipose‐derived mesenchymal stem cells for regenerative therapies. The aim of this study was to analyze human adipose tissue‐derived mesenchymal stem cells phenotypic expression

Bayesian Optimized Echo State Network Applied to Short-Term Load Forecasting

open access: yesEnergies, 2020
Load forecasting impacts directly financial returns and information in electrical systems planning. A promising approach to load forecasting is the Echo State Network (ESN), a recurrent neural network for the processing of temporal dependencies.

Synthesis and Characterization of PPV Monomer for Subsequent Electropolymerization

open access: yesJournal of Chemistry, Volume 2015, Issue 1, 2015., 2015
Organic synthesis of the monomer of poly(p‐phenylenevinylene) was performed starting by the 2,5‐dimethylphenol compound. An iodine atom was added to one end of the aromatic ring and then the iodine atom was substituted by a cyano group. Opposite to the cyano group was added a chain of six carbon atoms and the end of the carbon chain has an added ...

Detection of Total Phenol in Green and Black Teas by Flow Injection System and Unmodified Screen Printed Electrode

open access: yesInternational Journal of Analytical Chemistry, Volume 2010, Issue 1, 2010., 2010
A flow injection system using an unmodified gold screen‐printed electrode was employed for total phenol determination in black and green teas. In order to avoid passivation of the electrode surface due to the redox reaction, preoxidation of the sample was realized by hexacyanoferrate(III) followed by addition of an EDTA solution.

Development and Execution of an Impact Cratering Application on a Computational Grid

open access: yesScientific Programming, Volume 13, Issue 1, Page 19-30, 2005., 2005
Impact cratering is an important geological process of special interest in Astrobiology. Its numerical simulation comprises the execution of a high number of tasks, since the search space of input parameter values includes the projectile diameter, the water depth and the impactor velocity.
