A decade later, reviewing floating marine debris in Northern Chilean Patagonia
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-07-07)Floating marine debris (FMD) were abundantly reported in the Northern Chilean Patagonia in 2009 where seabased activities (mussel and salmon aquaculture) are responsible for most of them. Identifying the sources of FMD is ... -
A decentralized route to the origins of scaling in human language
(IOP PUBLISHING LTD, 2019)Zipf's law establishes that if the words of a (large) text are ordered by decreasing frequency, the frequency versus the rank decreases as a power law with exponent close to -1. Previous work has stressed that this statistical ... -
A description of Chilean food and nutrition health policies

A global metagenomic map of urban microbiomes and antimicrobial resistance
(CELL PRESS, 2021-06-24)We present a global atlas of 4,728 metagenomic samples from mass-transit systems in 60 cities over 3 years, representing the first systematic, worldwide catalog of the urban microbial ecosystem. This atlas provides an ... -
A HaloTag-TEV genetic cassette for mechanical phenotyping of proteins from tissues
(Nature Publishing Group, 2020-04-28)Single-molecule methods using recombinant proteins have generated transformative hypotheses on how mechanical forces are generated and sensed in biological tissues. However, testing these mechanical hypotheses on proteins ... -
A highly stable black phosphorene nanocomposite for voltammetric detection of clenbuterol
(SPRINGER WIEN, 2018)A nanocomposite was prepared from graphene-like two-dimensional black phosphorene (BP, an allotrope of phosphorus) and nafion (Nf) treated with isopropanol (IP). A glassy carbon electrode (GCE) modified with this nanocomposite ... -
A mechanistic approach for the optimization of loperamide loaded nanocarriers characterization: Diafiltration and mathematical modeling advantages
