Spin-lattice dynamics of surface vs core magnetization in Fe nanoparticles
(AIP Publishing, 2021-07-05)Magnetization of clusters is often simulated using atomistic spin dynamics for a fixed lattice. Coupled spin-lattice dynamics simulations of the magnetization of nanoparticles have, to date, neglected the change in the ... -
Sensing Electrochemical Signals Using a Nitrogen-Vacancy Center in Diamond
(MDPI, 2021-02)Chemical sensors with high sensitivity that can be used under extreme conditions and can be miniaturized are of high interest in science and industry. The nitrogen-vacancy (NV) center in diamond is an ideal candidate as a ... -
Viticultural Performance of Hybrids and Vitis vinifera Varieties Established in Annapolis Valley (Nova Scotia)
(MDPI, 2021-09)Cold-hardy interspecific hybrid grapes (CIHG) are well adapted to the Annapolis Valley edaphoclimatic conditions. The main characteristics of CIHG are the high bud hardiness tolerance to winter frost, the short growing ... -
Nutritional status differentially affect yield and must composition of hybrids and V. vinifera varieties established under cold climate conditions
(ESTACAO VITIVINICOLA NACIONAL, 2021-09)Nova Scotia is characterized by cold climate and acidic soils and high organic matter for viticultural development. There is little scientific information available about the nutritional management of grapevine varieties ... -
Assessing Ecological Indicators for Remnant Vegetation Strips as Functional Biological Corridors in Chilean Vineyards
(MDPI, 2021-09)Mediterranean central Chile is globally recognized as a hotspot for terrestrial biodiversity due to its high endemism and massive habitat loss. However, within the rural landscape of central Chile, significant extents of ... -
Effect of exogenous lipids on cryotolerance of Atlantic salmon (Salmo salar) spermatozoa
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2021-02)The development of semen cryopreservation strategies is necessary to improve the semen storage technologies of species of great commercial interest for aquaculture. Recent studies demonstrate that lipids play an important ... -
Global homogenization of the structure and function in the soil microbiome of urban greenspaces
(AMER ASSOC ADVANCEMENT SCIENCE, 2021-07)The structure and function of the soil microbiome of urban greenspaces remain largely undetermined. We conducted a global field survey in urban greenspaces and neighboring natural ecosystems across 56 cities from six ... -
Simulations of primary damage in a High Entropy Alloy: Probing enhanced radiation resistance
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-07)High Entropy Alloys (HEA) attract attention as possible radiation resistant materials, a feature observed in some experiments that has been attributed to several unique properties of HEA, in particular to the disorder-induced ... -
Nutritional status and sweet taste preference in Chilean adults
(ARCHIVOS LATINOAMERICANOS NUTRICION, 2020-12)El dramático aumento de la prevalencia e incidencia de la obesidad sugiere que factores ambientales y cambios en el estilo de vida contribuyen de forma importante a su tendencia epidémica. En humanos, se han reportado ... -
Enhanced Activity of Exportin-1/CRM1 in Neurons Contributes to Autophagy Dysfunction and Senescent Features in Old Mouse Brain
(HINDAWI LTD, 2021-08-16)Brain aging is characterized by dysfunctional autophagy and cellular senescence, among other features. While autophagy can either promote or suppress cellular senescence in proliferating cells, in postmitotic cells, such ... -
Seasonal precipitation in south-central Chile: Trends in extreme events since 1900
(UNAM. CENTRO CIENCIAS ATMOSFERA, 2021-09)We study a regional precipitation time series built upon seven meteorological records from south-central Chile (SCC; 37 degrees-42 degrees S), which altogether cover the period 1900-2019. As a first objective, we investigated ... -
Tree-ring-based hydroclimatic reconstruction for the northwest Argentine Patagonia since 1055 CE and its teleconnection to large-scale atmospheric circulation
(ELSEVIER, 2021-07)State-of-the-art climate models project droughts of stronger intensity and longer persistence in many arid and semi-arid regions such as northern Patagonia, which constitutes a serious concern worldwide. Moisture availability ... -
Growth of male and female Araucaria araucana trees respond differently to regional mast events, creating sex-specific patterns in their tree-ring chronologies
(ELSEVIER, 2021-03)Araucaria araucana is a dioecious evergreen conifer endemic from temperate forests of south Argentina and Chile. It is a long-lived species (maximum age > 1000 years), and it presents a high potential for tree-ring based ... -
High-Speed Bodyweight Resistance Training Improves Functional Performance Through Maximal Velocity in Older Females
(HUMAN KINETICS PUBL INC, 2021-08)The authors compared the effects of bodyweight resistance training at moderate- or high-speed conditions on muscle power, velocity of movement, and functional performance in older females. In a randomized, single-blinded ... -
Active School Breaks and Students' Attention: A Systematic Review with Meta-Analysis
(MDPI, 2021-06)School physical activity breaks are currently being proposed as a way to improve students' learning. However, there is no clear evidence of the effects of active school breaks on academic-related cognitive outcomes. The ... -
