Crustal Structure Beneath Mexico City From Joint Inversion of Receiver Functions and Dispersion Curves

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 8, August 2023., 2023
Abstract Over the years, it has been clear to seismologists that the crustal structure beneath Mexico City is highly complex. This fact may influence the seismic waves' behavior when traveling through it. Consequently, many studies have been done to understand this crustal structure.

Canadian contributions to environmetrics

Canadian Journal of Statistics, Volume 50, Issue 4, Page 1355-1386, December 2022., 2022
Abstract This article focuses on the importance of collaboration in statistics by Canadian researchers and highlights the contributions that Canadian statisticians have made to many research areas in environmetrics. We provide a discussion about different vehicles that have been developed for collaboration by Canadians in the environmetrics context as ...

Analysis of plant secondary metabolism using stable isotope‐labelled precursors

Phytochemical Analysis, Volume 32, Issue 1, Page 62-68, January/February 2021., 2021
Abstract Introduction Analysis of biochemical pathways typically involves feeding a labelled precursor to an organism, and then monitoring the metabolic fate of the label. Initial studies used radioisotopes as a label and then monitored radioactivity in the metabolic products.

A Chilean Berry Concentrate Protects against Postprandial Oxidative Stress and Increases Plasma Antioxidant Activity in Healthy Humans

Oxidative Medicine and Cellular Longevity, Volume 2017, Issue 1, 2017., 2017
This study formulated and characterized an antioxidant‐rich concentrate of berries (BPC‐350) produced in Chile, which was used to perform a crossover study aimed at determining the effect of the berries on the modulation of plasma postprandial oxidative stress and antioxidant status.

Medicinal Plants from North and Central America and the Caribbean Considered Toxic for Humans: The Other Side of the Coin

Evidence-Based Complementary and Alternative Medicine, Volume 2017, Issue 1, 2017., 2017
The consumption of medicinal plants has notably increased over the past two decades. People consider herbal products as safe because of their natural origin, without taking into consideration whether these plants contain a toxic principle. This represents a serious health problem.

Cytoprotective Mechanisms Mediated by Polyphenols from Chilean Native Berries against Free Radical‐Induced Damage on AGS Cells

Oxidative Medicine and Cellular Longevity, Volume 2017, Issue 1, 2017., 2017
The prevalence of cytoprotective mechanisms induced by polyphenols such as activation of intracellular antioxidant responses (ICM) and direct free radical scavenging was investigated in native Chilean species of strawberries, raspberries, and currants.

Bioassay Directed Isolation and Biological Evaluation of Compounds Isolated from Rubus fairholmianus Gard.

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
The in vitro and in silico analysis of Rubus fairholmianus acetone extract for antioxidant, antiproliferative, and anti‐inflammatory activity led to the isolation of six compounds. Amongst all the six isolated compounds tested, 1‐(2‐hydroxyphenyl)‐4‐methylpentan‐1‐one (compound 1) and 2‐[(3‐methylbutoxy) carbonyl] benzoic acid (compound 2) were found ...

Modelling Spatio‐Temporal Relevancy in Urban Context‐Aware Pervasive Systems Using Voronoi Continuous Range Query and Multi‐Interval Algebra

Mobile Information Systems, Volume 9, Issue 3, Page 189-208, 2013., 2013
Space and time are two dominant factors in context‐aware pervasive systems which determine whether an entity is related to the moving user or not. This paper specifically addresses the use of spatio‐temporal relations for detecting spatio‐temporally relevant contexts to the user.

Combined Acquisition and Tracking Methods for GPS L1 C/A and L1C Signals

International Journal of Navigation and Observation, Volume 2010, Issue 1, 2010., 2010
As part of the GPS modernization, the GPS L1 C/A signal will be augmented by the L1C signal. With this improvement, for the first time, several signals from the same constellation will be available at the same frequency. In this paper, an acquisition method is implemented to combine the GPS L1 C/A and L1C signals before correlation.
