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, 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 ...
-
(Frontiers Media, 2022)Schizophrenia (SZ) is a severe mental disorder that arises from abnormal neurodevelopment, caused by genetic and environmental factors. SZ often involves distortions in reality perception and it is widely associated with ...

(Pensoft Publisher, 2022)Itylos titicaca (Weyner 1890) has been reported to have a narrow distribution range associated with Andean wetlands called "bofedales" in Peru, Bolivia, northeast Chile and northwest Argentina. In Chile its distribution ...
-
(MDPI, 2022)Alien plant species are colonizing high-elevation areas along roadsides. In this study, we evaluated whether the distributions of alien plants in the central Chilean mountains have reached climatic equilibrium (i.e., upper ...
-
(MDPI, 2022)The Old Limachino Tomato is a valuable fruit with exceptional nutritional values and organoleptic sensory properties. However, it suffers from a short shelf-life, compromising post-harvest behavior. As an attempt to improve ...
