An Approach to Silhouette and Dunn Clustering Indices Applied to Big Data in Spark
(Springer, 2016)
K-Means and Bisecting K-Means clustering algorithms need the optimal number into which the dataset may be divided. Spark implementations of these algorithms include a method that is used to calculate this number. Unfortunately, ...

Development of behavioral parameters and ERPs in a novel-target visual detection paradigm in children, adolescents and young adults
(Springer Verlag, 2015)
Background: The present study analyzes the development of ERPs related to the process of selecting targets based on their novelty. Methods: One hundred and sixty-seven subjects from 6 to 26 years old were recorded with 30 ...

Soil phenanthrene phytoremediation capacity in bacteria-assisted Spartina densiflora
(Elsevier, 2019-10-30)
Polycyclic aromatic hydrocarbons (PAH) have become a threat for the conservation of wetlands worldwide. The halophyte Spartina densiflora has shown to be potentially useful for soil phenanthrene phytoremediation, but no ...

Lethality caused by ADP-glucose accumulation is suppressed by salt-induced carbon flux redirection in cyanobacteria
(Oxford University Press, 2020)
Cyanobacteria are widely distributed photosynthetic organisms. During the day they store carbon, mainly as glycogen, to provide the energy and carbon source they require for maintenance during the night. Here, we generate ...

Mean-field and two-body nuclear effects in inclusive electron scattering on argon, carbon, and titanium: The superscaling approach
(American Physical Society, 2019)
We compare the predictions of the superscaling approach (SuSAv2) model including two-particle two-hole meson-exchange currents with the recent JLab data for inclusive electron scattering on three different targets (C, Ar, ...

Efficient stereoselective synthesis of 2-acetamido-1,2-dideoxyallonojirimycin (DAJNAc) and sp2-iminosugar conjugates: Novel hexosaminidase inhibitors with discrimination capabilities between the mature and precursor forms of the enzyme
(Elsevier, 2016)
Due to their capacity to inhibit hexosaminidases, 2-acetamido-1,2-dideoxy-iminosugars have been widely studied as potential therapeutic agents for various diseases. An efficient stereoselective synthesis of 2-acetamido-1 ...

Limestone calcination under calcium-looping conditions for CO2 capture and thermochemical energy storage in the presence of H2O: An in situ XRD analysis
(Royal Society of Chemistry, 2017)
This work reports an in situ XRD analysis of whether the calcination/carbonation behavior of natural limestone (CaCO3) is affected by the addition of H2O to the calciner at a very low concentration under relevant Calcium-Looping ...
