On the Right Track to Treat Movement Disorders: Promising Therapeutic Approaches for Parkinson's and Huntington's Disease
(Frontiers Media S.A., 2020-09)Movement disorders are neurological conditions in which patients manifest a diverse range of movement impairments. Distinct structures within the basal ganglia of the brain, an area involved in movement regulation, are ... -
On studying the patterns of individual-based tree mortality in natural forests: A modelling analysis
(Elsevier, 2020-11)Tree mortality is a critical ecological phenomenon shaping forest ecosystem dynamics, structure, and composition, while its effects are of global relevance due to its relationship with forest conditions and environmental ... -
Personas mayores en Chile: el nuevo desafío social, económico y sanitario del siglo XXI
(Sociedad Medica de Santiago, 2020-06)Ageing will be one of the most significant social transformations of the 21st century worldwide. In the last 40 years, Chile has tripled its older adult population. As a result, by 2050 the country will have the highest ... -
Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role
(Elsevier, 2020-06)Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility. However, the exact role displayed by their grain structure in mechanical properties has not been yet fully understood. Here, ... -
Multi-Objective Optimization for Personalized Prediction of Venous Thromboembolism in Ovarian Cancer Patients
(Institute of Electrical and Electronics Engineers Inc., 2020-05)Thrombotic events are one of the leading causes of mortality and morbidity related to cancer, with ovarian cancer having one of the highest incidence rates. The need to prevent these events through the prescription of ... -
Molecular dynamics simulations of thermal conductivity between two nanoparticles in contact
(American Institute of Physics, 2020-06)The nanoscale properties of materials can have a great influence on their macroscopic behavior; for instance, the generation and accumulation of defects at the nanoscale, such as point defects, porosity, and interfaces, ... -
Modeling habitat suitability and spread dynamics of two invasive rose species in protected areas of Mendoza, Argentina
(Elsevier, 2020-12)Biological invasions are a main threat to biodiversity and natural resources, which calls for studies that identify the regions that present the greatest invasion risks. We assessed the potential distribution of two ... -
Mining sequences in activities for time use analysis
(IOS Press, 2020-05)By providing a complete record of time use for a given population, time use studies enable investigators to test various hypotheses concerning that behavior. However, the large number and variety of activity combinations ... -
MeV irradiation of tungsten nanowires: structural modifications
(IOP Publishing Ltd., 2020-05)In this work we use the Two Temperature Model coupled to Molecular Dynamics (TTM-MD) to study swift heavy ion irradiation of W finite nanowires. Au projectiles are considered with energies ranging from 20 to 50 MeV, which ... -
Melatonin triggers metabolic and gene expression changes leading to improved quality traits of two sweet cherry cultivars during cold storage
(Elsevier Ltd., 2020-07)Sweet cherry is a valuable non-climacteric fruit with elevated phytonutrients, whose fruit quality attributes are prone to rapid deterioration after harvest, especially peel damage and water loss of stem. Here the metabolic ... -
Mapping Land Cover and Tree Canopy Cover in Zagros Forests of Iran: Application of Sentinel-2, Google Earth, and Field Data
(MDPI Multidisciplinary Digital Publishing Institute, 2020-06)The Zagros forests in Western Iran are valuable ecosystems that have been seriously damaged by human interference (harvesting the wood and forest sub-products, converting the forests to the agricultural lands, and grazing) ... -
Magnon valley Hall effect in CrI3-based van der Waals heterostructures
(American Physical Society, 2020-05)Magnonic excitations in the two-dimensional (2D) van der Waals (vdW) ferromagnet chromium triiodide (CrI3) are studied. We find that bulk magnons exhibit a nontrivial topological band structure without the need for ... -
