Association Between Walking Pace and Stroke Incidence Findings From the UK Biobank Prospective Cohort Study
(Lippincott Williams and Wilkins Ltd., 2020-05)
Background and Purpose- Stroke incidence in younger and middle-aged people is growing. Despite this, its associations in this subset of the stroke population are unknown, and prevention strategies are not tailored to meet ...
Deciphering the functional diversity of DNA-binding transcription factors in Bacteria and Archaea organisms
(Public Library of Science, 2020-08)
DNA-binding Transcription Factors (TFs) play a central role in regulation of gene expression in prokaryotic organisms, and similarities at the sequence level have been reported. These proteins are predicted with different ...
Connectivity of bacterial assemblages along the Loa River in the Atacama Desert, Chile
(PeerJ Inc., 2020-10)
The Loa River is the only perennial artery that crosses the Atacama Desert in northern Chile. It plays an important role in the ecological and economic development of the most water-stressed region, revealing the impact ...
Distinct oxygen environments shape picoeukaryote assemblages thriving oxygen minimum zone waters off central Chile
(Oxford University Press, 2020-09)
Oxygen minimum zones (OMZs) support ocean biogeochemical cycles of global importance. The OMZ off central Chile is characterized by seasonally variable oxygen concentrations due to upwelling events. Bacterial and archaeal ...
Characterizing growth rings in the trees of Peru: A wood anatomical overview for potential applications in dendroecological-related fields
(Elsevier GmbH, 2020-08)
Sustainable forestry requires accurate ecological information such as species composition, growth rates and recruitment dynamics. Tree growth rates are usually obtained through long-term periodic re-measurements of individual ...
Discriminative learning and associative memory under the differential outcomes procedure is modulated by cognitive load
(Elsevier, 2020-07)
Working memory (WM) has been thought to be the cause of associative memory deficits in older adults. Previous research has demonstrated the benefits of a discriminative learning procedure, the differential outcomes procedure ...
Core-periphery dynamics in a plant-pollinator network
(Wiley-Blackwell Publishing Ltd, 2020-07)
Mutualistic networks are highly dynamic, characterized by high temporal turnover of species and interactions. Yet, we have a limited understanding of how the internal structure of these networks and the roles species play ...
Height growth-rate at a given height: A mathematical perspective for forest productivity
(Elsevier, 2020-09)
Understanding the height growth of trees is a fundamental component for scientific knowledge and management of forest ecosystems. The height of dominant trees at a reference-age, commonly known as the site-index, is the ...
Socio-demographic patterns of public, private and active travel in Latin America: Cross-sectional findings from the ELANS study
(Elsevier BV, 2020-03)
Background: Active travel such as walking or cycling has been associated with more favorable health outcomes. However, evidence on patterns of transportation in Latin America is scarce. Therefore, the aim of this study was ...
