(Nature, 2022)Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong ...
-
(Frontiers Media, 2022)In the first paper of this series, the authors derived an expression for the interaction energy between two reagents in terms of the chemical reactivity indicators that can be derived from density functional perturbation ...
-
(MDPI, 2022)Jubaea chilensis (Molina) Baill., also named Chilean palm, is an endemic species found in the coastal area of Mediterranean sclerophyllous forest in Chile. It has a highly restricted and fragmented distribution along the ...

(Elsevier, 2023)Context . Millions of learners worldwide experience mathematics nowadays as an inescapable tool of cognitive abuse and punitive selection. Most traditional teaching thwarts natural human cognitive resources. Problem . We ...
-
(Planeta, 2023)Lejos de lo que suponemos, las matemáticas no son una disciplina rígida, sino que conecta distintas áreas de nuestras vidas. En la Antigua Grecia, por ejemplo, y luego de varias observaciones, Pitágoras estableció que había ...
-
(Universidad de Chile, 2023)El bosque higrófilo de quebrada, un elemento azonal del bosque esclerófilo, es un ecosistema altamente amenazado por el creciente aumento de la frecuencia e intensidad de los incendios forestales y supone un desafío para ...
-
(Universidad de Chile, 2023)In the inner heliosphere, space measurements have revealed that plasma can be described by the Kappa distributions family, which are characterized by the value of κ, indicating how far plasma is from the ideal Maxwell-Boltzmann ...

-
(Universidad de Chile, 2023)Este trabajo se centra en la descripción estructural de compósitos híbridos formados por una matriz inorgánica a base de especies derivadas de óxido de Zn o de Ti y una fase orgánica formada por el anión del ácido esteárico. ...
-
(Universidad de Chile, 1975)El objeto de este estudio es poder explicar la disminución en la conversión del propileno al aumentar la temperatura, mas allá de los 180°C
-
(Universidad de Chile, 1975)La presente investigaci6n tiene por objeto determinar potenciométricamente cobalto (11) con ferricianuro de potasio en medio tamponado con cloruro de amonio-amoníaco
-
(Centers Disease Control & Prevention, 2022)Dissemination of carbapenemase-encoding plasmids by horizontal gene transfer in multidrug-resistant bacteria is the major driver of rising carbapenem-resistance, but the conjugative mechanics and evolution of clinically ...
-
(Lippincott Williams & Wilkins, 2022)Purpose of review The vascular hypothesis of schizophrenia (SZ) postulates that brain endothelial dysfunction contributes to brain pathophysiology. This review discusses recent evidence for and against this hypothesis, ...

(Universidad de Chile, 2023)La proteína quinasa dependiente de ciclina 5 (Cdk5) juega un papel fundamental en diversos procesos fisiológicos y patológicos del sistema nervioso central y periférico, incluyendo funciones en los ganglios de la raíz ...
-
The impact of the suppression of highly connected protein interactions on the corona virus infection (Nature, 2022)Several highly effective Covid-19 vaccines are in emergency use, although more-infectious coronavirus strains, could delay the end of the pandemic even further. Because of this, it is highly desirable to develop fast ...
-
(Frontiers Media, 2022)There is wide observational evidence that electron velocity distribution functions (eVDF) observed in the solar wind generally present enhanced tails and field-aligned skewness. These properties may induce the excitation ...
-
(MDPI, 2022)Several metals belong to a group of non-biodegradable inorganic constituents that, at low concentrations, play fundamental roles as essential micronutrients for the growth and development of plants. However, in high ...
-
(Frontiers Media, 2022)Prolonged changes in neural activity trigger homeostatic synaptic plasticity (HSP) allowing neuronal networks to operate within functional ranges. Cell-wide or input-specific adaptations can be induced by pharmacological ...
-
(Universidad de Chile, 2023)La muda, el reemplazo de plumas, corresponde a un estado de historia de vida crucial para la supervivencia de las aves en el largo plazo. Altamente demandante, la expresión y desarrollo de la muda depende de una alta ...
-
(Universidad de Chile, 2022)In this thesis we mainly prove two results in an algebro-geometric way: If one has a curve Γ of (honest) quadrisecant planes to the Kummer variety of an indecomposable principally abelian variety (X,Θ) then the curve Γ ...
