Quantum Discord, Thermal Discord, and Entropy Generation in the Minimum Error Discrimination Strategy
(MDPI, 2019)We study the classical and quantum correlations in the minimum error discrimination (ME) of two non-orthogonal pure quantum states. In particular, we consider quantum discord, thermal discord and entropy generation. We ... -
Molecular simulations of carbon allotropes in processes with creation and destruction of chemical bonds
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)The development of sophisticated interatomic potentials for classical molecular dynamics and Monte Carlo simulations has several advantages, but also some drawbacks. One of them is the increase in their complexity, which ... -
Potential distribution model of Leontochir ovallei using remote sensing data
(UNIV POLITECNICA VALENCIA, EDITORIAL UPV, 2019)Predicting the potential distribution of short-lived species with a narrow natural distribution range is a difficult task, especially when there is limited field data. The possible distribution of L. ovallei was modeled ... -
Whole Genome Sequence, Variant Discovery and Annotation in Mapuche-Huilliche Native South Americans
(NATURE PUBLISHING GROUP, 2019)Whole human genome sequencing initiatives help us understand population history and the basis of genetic diseases. Current data mostly focuses on Old World populations, and the information of the genomic structure of Native ... -
Intermediate-Salinity Systems at High Altitudes in the Peruvian Andes Unveil a High Diversity and Abundance of Bacteria and Viruses
(MDPI, 2019)Intermediate-salinity environments are distributed around the world. Here, we present a snapshot characterization of two Peruvian thalassohaline environments at high altitude, Maras and Acos, which provide an excellent ... -
Tracing the phylogenetic history of the Crl regulon through the Bacteria and Archaea genomes
(BMC, 2019)Background: Crl, identified for curli production, is a small transcription factor that stimulates the association of the sigma(S) factor (RpoS) with the RNA polymerase core through direct and specific interactions, increasing ... -
Effect of CO2 Concentration on Uptake and Assimilation of Inorganic Carbon in the Extreme Acidophile Acidithiobacillus ferrooxidans
(FRONTIERS MEDIA SA, 2019)This study was motivated by surprising gaps in the current knowledge of microbial inorganic carbon (Ci) uptake and assimilation at acidic pH values (pH < 3). Particularly striking is the limited understanding of the ... -
ATP6V(0)d2 controls Leishmania parasitophorous vacuole biogenesis via cholesterol homeostasis
(PUBLIC LIBRARY SCIENCE, 2019)V-ATPases are part of the membrane components of pathogen-containing vacuoles, although their function in intracellular infection remains elusive. In addition to organelle acidification, V-ATPases are alternatively implicated ... -
Non-lysosomal Activation in Macrophages of Atlantic Salmon (Salmo salar) After Infection With Piscirickettsia salmonis
(FRONTIERS MEDIA SA, 2019)Piscirickettsia salmonis is a facultative intracellular pathogen and etiological agent of the systemic disease salmonid rickettsial septicemia. It has been suggested that P salmonis is able to survive in host macrophages, ... -
Uncovering the Mechanisms of Halotolerance in the Extremely Acidophilic Members of the Acidihalobacter Genus Through Comparative Genome Analysis
(FRONTIERS MEDIA SA, 2019)There are few naturally occurring environments where both acid and salinity stress exist together, consequently, there has been little evolutionary pressure for microorganisms to develop systems that enable them to deal ... -
Identification of functional signatures in the metabolism of the three cellular domains of life
(PUBLIC LIBRARY SCIENCE, 2019)In order to identify common and specific enzymatic activities associated with the metabolism of the three cellular domains of life, the conservation and variations between the enzyme contents of Bacteria, Archaea, and ... -
Signal peptide recognition in Trypanosoma cruzi GP82 adhesin relies on its localization at protein N-terminus
(NATURE PUBLISHING GROUP, 2019)Trypanosoma cruzi, the causative agent of Chagas disease, has a dense coat of GPI-anchored virulence factors. T. cruzi GPI-anchored adhesin GP82 is encoded by a repertoire of transcripts containing several in-frame initiation ... -
Identification and Unusual Properties of the Master Regulator FNR in the Extreme Acidophile Acidithiobacillus ferrooxidans
(FRONTIERS MEDIA SA, 2019)The ability to conserve energy in the presence or absence of oxygen provides a metabolic versatility that confers an advantage in natural ecosystems. The switch between alternative electron transport systems is controlled ... -
NOTCH3 Gene Mutation in a Chilean Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy Family
(ELSEVIER, 2020)Introduction: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a rare hereditary stroke disorder caused by mutations in the NOTCH3 gene. We report the first Chilean ... -
Evaluation of the Abundance of DNA-Binding Transcription Factors in Prokaryotes
(MDPI, 2020)The ability of bacteria and archaea to modulate metabolic process, defensive response, and pathogenic capabilities depend on their repertoire of genes and capacity to regulate the expression of them. Transcription factors ... -
Relationship between photo-physical and electrochemical properties of D--A compounds regarding solar cell applications. 1. Substituent type effect in photovoltaic performance
(SPRINGER, 2019)Studying the electrochemical characteristics is an important step for determining interactions between molecules and the chemical environment. Moreover, the electrochemical evaluation of dyes is highly needed to establish ... -
Physical-chemical properties of M@Fe3O4 core@shell nanowires (M = Cu, Co, CoO)
(ROYAL SOC CHEMISTRY, 2019)Interest in low dimensional magnetic systems has been growing due to the novel and dramatically differentiated effects of their physical properties, which give them special behaviors and uses in biomedical, environmental ... -
Global ecological predictors of the soil priming effect
