Climate and coastal low-cloud dynamic in the hyperarid Atacama fog Desert and the geographic distribution of Tillandsia landbeckii (Bromeliaceae) dune ecosystems
(SPRINGER WIEN, 2021-10)Despite the extensive area covered by the coastal Atacama fog Desert (18-32 degrees S), there is a lack of understanding of its most notorious characteristics, including fog water potential, frequency of fog presence, ... -
Climate signals from intra-annual wood density fluctuations in Abies durangensis
(BRILL ACADEMIC PUBLISHERS, 2019)Ongoing climate change is expected to alter forests by affecting forest productivity, with implications for the ecological functions of these systems. Despite its great dendrochronological potential, little research has ... -
Climate signals in tree rings of Paubrasilia echinata (Leguminosae-Caesalpinioidea) from the Atlantic Forest of Brazil
(SPRINGER HEIDELBERG, 2020)Key message Tree-ring chronologies were built for wild and cultivated Paubrasilia echinata, a presently endangered species. Significantly P. echinata showed measurably different growth patterns related to the environment ... -
Climate variability of the southern Amazon inferred by a multi-proxy tree-ring approach using Cedrelafissilis Vell
(ELSEVIER, 2023-02-01)The analysis of climate variability and development of reconstructions based on tree-ring records in tropical forests have been increasing in recent decades. In the Amazon region, ring width and stable isotope long-term ... -
Climatic controls of decomposition drive the global biogeography of forest-tree symbioses
(NATURE PUBLISHING GROUP, 2019)The identity of the dominant root-associated microbial symbionts in a forest determines the ability of trees to access limiting nutrients from atmospheric or soil pools(1,2), sequester carbon(3,4) and withstand the effects ... -
Climatic vulnerabilities and ecological preferences of soil invertebrates across biomes
(WILEY, 2020)Unlike plants and vertebrates, the ecological preferences, and potential vulnerabilities of soil invertebrates to environmental change, remain poorly understood in terrestrial ecosystems globally. We conducted a cross-biome ... -
Clinical and epidemiological features of myasthenia gravis in Chilean population
(WILEY, 2018)ObjectiveTo provide an estimated prevalence and describe the clinical features of myasthenia gravis (MG) in Chile. MethodWe carried out (i) a prevalence study of MG using the capture-recapture method and the hospital ... -
Clinical and pulmonary function analysis in long-COVID revealed that long-term pulmonary dysfunction is associated with vascular inflammation pathways and metabolic syndrome
(Frontiers Media S.A., 2023-10)Introduction: Long-term pulmonary dysfunction (L-TPD) is one of the most critical manifestations of long-COVID. This lung affection has been associated with disease severity during the acute phase and the presence of ... -
Clinical, imaging and genetic analysis of double bilateral radix entomolaris
(CIENCIAS, 2015)Background: Anatomy describes that first mandibular molars have two roots: 1 mesial, with 2 root canals, and 1 distal, with 1 root canal. The presence of three roots in these teeth is uncommon. Root anatomical variations ... -
Clostridium difficile: un patógeno emergente en Medicina Veterinari
(Facultad de Ciencias, 2012)Clostridium difficile es un bacilo Gram positivo esporulado que forma parte de la microbiota intestinal del hombre y animales domésticos y es una causa establecida de diarrea y colitis pseudomembranosa. Este microorganismoes ... -
La co-enseñanza desde enfoques inclusivos para los equipos del Programa de Integración Escolar
(Universidad Austral de Chile. Facultad de Filosofía y Humanidades, 2021)En Chile los equipos del Programa de Integración Escolar tienen el desafío de empoderar a los docentes en la aplicación de la co-enseñanza como estrategia de trabajo colaborativo para la atención a la diversidad y la ... -
Co-existence and switching between fast and Omega-slow wind solutions in rapidly rotating massive stars
(OXFORD UNIV PRESS, 2018)Most radiation-driven winds of massive stars can be modelled with m-CAK theory, resulting in the so-called fast solution. However, the most rapidly rotating stars among them, especially when the rotational speed is higher ... -
Coagulation Factor Xa Promotes Solid Tumor Growth, Experimental Metastasis and Endothelial Cell Activation
(MDPI, 2019)Hypercoagulable state is linked to cancer progression; however, the precise role of the coagulation cascade is poorly described. Herein, we examined the contribution of a hypercoagulative state through the administration ... -
Coalition incentives and party bias in Chile
(ELSEVIER SCI LTD, 2021-08-01)This article revisits the debate over Chile's binomial electoral rules and its consequences and examines how the new electoral system conceived by a democratic congress altered political competition. It utilizes a seat-vote ... -
Coding closed and open quantum systems in MATLAB: applications in quantum optics and condensed matter
(IOP PUBLISHING LTD, 2020-07)We develop a package of numerical simulations implemented in MATLAB to solve complex many-body quantum systems. We focus on widely used examples that include the calculation of the magnetization dynamics for the closed and ... -
Cognitive impairment in heart failure is associated with altered Wnt signaling in the hippocampus
(IMPACT JOURNALS LLC, 2019)Age represents the highest risk factor for death due to cardiovascular disease. Heart failure (HF) is the most common cardiovascular disease in elder population and it is associated with cognitive impairment (CI), diminishing ... -
Coherence as a measure for non-Markovianity and its applications to color centers in diamond
(American Physical Society, 2019-04-30)The degree of non-Markovianity of a continuous bath can be quantified by means of the coherence. This simple measure is experimentally accessible through Ramsey spectroscopy, but it is limited to incoherent dynamical maps. ... -
Coherent population trapping with a controlled dissipation: applications in optical metrology
(IOP PUBLISHING LTD, 2018)We analyze the properties of a pulsed coherent population trapping protocol that uses a controlled decay from the excited state in a Lambda-level scheme. We study this problem analytically and numerically and find regimes ... -
