UV Resistance and Photoreactivation of Extremophiles from High-Altitude Andean Lakes
(Elsevier, 2013-04)
He HAAL are natural laboratories for exploring and monitoring in situ interactions between the geophysical environment and the dynamics of biodiversity. Solar irradiation (including high UV-B doses) is without doubt the ...
Hanseniaspora smithiae sp. nov., a Novel Apiculate Yeast Species From Patagonian Forests That Lacks the Typical Genomic Domestication Signatures for Fermentative Environments
(Frontiers Media, 2021-07)
During a survey of Nothofagus trees and their parasitic fungi in Andean Patagonia (Argentina), genetically distinct strains of Hanseniaspora were obtained from the sugar-containing stromata of parasitic Cyttaria spp. ...
Relative entropy for coherent states from Araki formula
(American Physical Society, 2019-06-28)
We make a rigorous computation of the relative entropy between the vacuum state and a coherent state for a free scalar in the framework of algebraic description of quantum field theory (AQFT). We study the case of the ...
Mitochondrial regulation of cell cycle and proliferation
(Mary Ann Liebert, 2012-05)
Eukaryotic mitochondria resulted from symbiotic incorporation of α-proteobacteria into ancient archaea species. During evolution, mitochondria lost most of the prokaryotic bacterial genes and only conserved a small fraction ...
Intrinsically disordered linkers impart processivity on enzymes by spatial confinement of binding domains
(Multidisciplinary Digital Publishing Institute, 2019-05)
(1) Background: Processivity is common among enzymes and mechanochemical motors that synthesize, degrade, modify or move along polymeric substrates, such as DNA, RNA, polysaccharides or proteins. Processive enzymes can ...
Benchmarking the Variational Reduced Density Matrix Theory in the Doubly Occupied Configuration Interaction Space with Integrable Pairing Models
(American Chemical Society, 2018-08)
The variational reduced density matrix theory has been recently applied with great success to models within the truncated doubly occupied configuration interaction space, which corresponds to the seniority zero subspace. ...
Comparative sperm ultrastructure of two tegu lizards (genus Salvator) and its relation to sperm competition
(Elsevier Gmbh, 2017-03)
The knowledge of sperm ultrastructure of Squamata provides informative traits for phylogenetic analyses. Furthermore, several sperm ultrastructure traits are important for sperm motility and longevity. Here, we provided a ...
Natural modes of the two-fluid model of two-phase flow
(American Institute of Physics, 2021-03)
A physically based method to derive well-posed instances of the two-fluid momentum transport equations from first principles is presented. The basic tools used in this endeavor are the variational principles of field theory, ...
Regional patterns of ecosystem functional diversity in the Argentina Pampas using MODIS time-series
(Elsevier Science, 2018-01)
The characterization of ecosystem functioning is significant for different purposes such as biodiversity conservation and ecosystem services. A key aspect of ecosystem functioning is carbon gains, since it represents the ...
Mechanical rotation via optical pumping of paramagnetic impurities
(American Physical Society, 2019-12-06)
Hybrid quantum systems exhibiting coupled optical, spin, and mechanical degrees of freedom can serve as a platform for sensing, or as a bus to mediate interactions between qubits with disparate energy scales. These systems ...
