Global‐Krigger: A Global Kriging Interpolation Toolbox With Paleoclimatology Examples

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 6, June 2023., 2023
Abstract Many applications in Earth sciences require spatial prediction, that is, obtaining a continuous scalar field from a set of discrete scalar data points on the Earth's surface. Such applications include model‐data comparisons and derivation of continuous scalar fields as input for Earth system models. The advantage of kriging as an interpolation

Multi‐parametric liver tissue characterization using MR fingerprinting: Simultaneous T1, T2, T2*, and fat fraction mapping

Magnetic Resonance in Medicine, Volume 84, Issue 5, Page 2625-2635, November 2020., 2020
Purpose Quantitative T1, T2, T2*, and fat fraction (FF) maps are promising imaging biomarkers for the assessment of liver disease, however these are usually acquired in sequential scans. Here we propose an extended MR fingerprinting (MRF) framework enabling simultaneous liver T1, T2, T2*, and FF mapping from a single ~14 s breath‐hold scan.

An algebraic alternative for the accurate simulation of CO2 Raman spectra

Journal of Raman Spectroscopy, Volume 51, Issue 3, Page 569-583, March 2020., 2020
An accurate simulation of the Raman spectrum of the carbon dioxide molecule has been presented. A detail analysis of the Hamiltonian interactions taking into account the 178 experimental energies available in the literature has been provided. The three polyads schemes have been considered and an inspection of the spectrum seems to show a slight ...

Computational Molecular Modeling of Pin1 Inhibition Activity of Quinazoline, Benzophenone, and Pyrimidine Derivatives

Journal of Chemistry, Volume 2019, Issue 1, 2019., 2019
Pin1 (peptidyl‐prolyl cis-trans isomerase NIMA‐interacting 1) is directly involved in cancer cell‐cycle regulation because it catalyses the cis‐trans isomerization of prolyl amide bonds in proteins. In this sense, a modeling evaluation of the inhibition of Pin1 using quinazoline, benzophenone, and pyrimidine derivatives was performed by using ...

Complexity‐Based Discrepancy Measures Applied to Detection of Apnea‐Hypopnea Events

Complexity, Volume 2018, Issue 1, 2018., 2018
In recent years, an increasing interest in the development of discriminative methods based on sparse representations with discrete dictionaries for signal classification has been observed. It is still unclear, however, what is the most appropriate way for introducing discriminative information into the sparse representation problem.

Genetic Diversity and Distribution of Blastocystis Subtype 3 in Human Populations, with Special Reference to a Rural Population in Central Mexico

BioMed Research International, Volume 2018, Issue 1, 2018., 2018
Blastocystis subtype 3 (ST3) is a parasitic protist found in the digestive tract of symptomatic and asymptomatic humans around the world. While this parasite exhibits a high prevalence in the human population, its true geographic distribution and global genetic diversity are still unknown.

Assessment of Functionals for First‐Principle Studies of the Structural and Electronic Properties of δ‐Bi2O3

Advances in Condensed Matter Physics, Volume 2015, Issue 1, 2015., 2015
Fully relativistic full‐potential density functional calculations with an all‐electron linearized augmented plane waves plus local orbitals method were carried out to perform a comparative study on the structural and electronic properties of the cubic oxide δ‐Bi2O3 phase, which is considered as one of the most promising materials in a variety of ...
