    “…We applied both the ordinary linear regression (OLR) and the new uncertainty weighted linear regression (UWLR) models for the calibration and comparison of a XRF machine through 59 geochemical reference materials (GRMs) and a procedure blank sample. )e mean concentration and uncertainty data for the GRMs used for the calibrations (Supplementary Materials) (available here) filewere achieved from an up-to-date compilation of chemical data and their processing from well-known discordancy and significance tests. )e drift-corrected XRF intensity and its uncertainty were determined from mostly duplicate pressed powder pellets. )e comparison of the OLR (linear correlation coefficient r∼0.9523–0.9964 and 0.9771–0.9999, respectively, for before and after matrix correction) and UWLR models (r∼0.9772–0.9976 and 0.9970–0.9999, respectively) clearly showed that the latter with generally higher values of r is preferable for routine calibrations of analytical procedures. …”

    La relevancia de la perspectiva territorial y femenina en la construcción de paz en Colombia = The Relevance of the Territorial and Female Perspective in the Peace Building in Colo... por Cabello Tijerina, Paris Alejandro, Quiñonez Díaz, Karen Andrea

    Publicado 2019
    “…For this reason, a qualitative tool was developed consisting of a semi-structured in-depth interview in which it was observed that peace has ceased to be a matter for States and has become a matter for citizens, even though women’s contributions to peacebuilding in the country are scarce. Thus, the advances achieved through the theorization of peace must be materialized in reality in such a way that the construction of peace as a process that concerns all citizens involves women not only in the political sphere but also in their daily lives.…”

    A Real-Time SOSM Super-Twisting Technique for a Compound DC Motor Velocity Controller por Morfin, Onofre A., Castañeda, Carlos E., Valderrabano González, Antonio, Hernandez González, Miguel, Valenzuela, Fredy A.

    Publicado 2017
    “…This scheme is based on the state-feedback linearization technique combined with a second-order sliding mode algorithm, named super-twisting, for stabilizing the system and achieving control goals. The control law is designed to track a periodic square reference signal, being one of the most severe tests applied to closed-loop systems. …”
