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, 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 ... -
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 ... -
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 ... -
Colgajo miocutáneo de gastrocnemius medial con isla triangular de piel y cierre en V-Y
(CIENCIAS, 2009)Para corregir defectos cutáneos con exposición de fractura de tibia a nivel del tercio proximal, una buena alternativa es el colgajo miocutáneo de gastrocnemius medial con isla triangular de piel con cierre en V-Y. Las ... -
Collateral Sprouting of Peripheral Sensory Neurons Exhibits a Unique Transcriptomic Profile
(Humana Press, 2020-10)Peripheral nerve injuries result in motor and sensory dysfunction which can be recovered by compensatory or regenerative processes. In situations where axonal regeneration of injured neurons is hampered, compensation by ... -
Collateral Ventilation: A Terminologia Histologica Proposal
(SOC CHILENA ANATOMIA, 2019)The correct use of morphological terms is standardized by the Terminologies, one of them is the Histological Terminology (HT) For these Terminologies, the exclusion of eponyms is recommended. Despite this, there are ... -
Collective memories and present-day intergroup relations: Introduction to the special thematic section
(PsychOpen, 2017)This special thematic section aims to bring together current research on the connections between collective memories - or representations of history - and present-day intergroup relations. Drawing from a multitude of ... -
Collisions between amorphous carbon nanoparticles: phase transformations
(EDP Sciences, 2020-09)Context. Collisions of nanoparticles (NPs) occur in dust clouds and protoplanetary disks.Aims. Sticking collisions lead to the growth of NPs, in contrast to bouncing or even fragmentation events and we aim to explore these ... -
