(Universidad de Chile, 2021)Esta tesis tiene como objetivo principal el estudio de la sucesión (M n), de los llamados chain-maxima (máximos en cadena), bajo la hipótesis de observaciones independientes e idénticamente distribuidas (iid), con valores ...
-
(Wiley, 2022)Anthropogenic-based disturbances may alter peatland soil-plant causal associations and their ability to sequester carbon. Likewise, it is unclear how the vegetation attributes are linked with different soil C decomposition-based ...
-
(AMER CHEMICAL SOC, 2011-09)The metabolic profile of Streptomyces sp. strain C34, isolated from the Chilean hyper-arid Atacama Desert soil, is dependent on the culture media used for its growth. The application of an OSMAC approach on this strain ...

(Bauru School of Dentistry, University of Sao Paulo, 2019)Amelogenesis imperfecta (AI) is a group of enamel development disorders that alter the structure and chemical composition of the tissue. There is great variability in the clinical presentation; according to Witkop, AI can ...
-
(Royal Soc Chemistry, 2021)Self-propelled swimmers such as bacteria agglomerate into clusters as a result of their persistent motion. In 1D, those clusters do not coalesce macroscopically and the stationary cluster size distribution (CSD) takes an ...
-
(Springer, 2016)We study the foreshocks and aftershocks of the 1 April 2014 Iquique earthquake of Mw 8.1. Most of these events were recorded by a large digital seismic network that included the Northern Chile permanent network and up to ...
-
(Universidad de Chile, 2023)Clinical coding is the task of transforming medical documents into structured codes following a standard ontology. Since these terminologies are composed of thousands of codes, this problem can be considered an Extreme ...
