Global maps of Biodiversity Intactness Index (Sanchez-Ortiz et al., 2019 - bioRxiv )
Global maps of biodiversity intactness for the year 2005 (abundance-based BII and richness-based BII). These high-resolution rasters were used to plot Figure 1 in "Land-use and related pressures have reduced biotic integrity more on islands than on mainlands" (Sanchez-Ortiz et al., 2019). We have updated methods previously used to estimate BII globally (Newbold et al., 2016) to allow pressure effects to differ between islands and mainlands, while also implementing some other recent improvements in modelling

Los niveles superiores a 2000 m conducen a generar respuestas de adaptación sistémica que van desde lo hematológico a lo cardiovascular, y en algunas situaciones pueden no favorecer los resultados obtenidos por el individuo evaluado, sin tener realmente un bajo nivel de condición aeróbica o de resistencia; Teniendo en cuenta lo anterior, es de vital importancia establecer si hay validaciones de esta prueba que se hayan ajustado a la población que entrena en las alturas, para reconocerlas y ajustarlas o, por el contrario, si no, que esto es El marco que invita a la estandarización de estos valores y ponerlos a disposición de la comunidad académica y deportiva.Levels above 2000 m, leads to generate systemic adaptation responses ranging from the hematological to the cardiovascular, and in some situations may not favor the results obtained by the evaluated individual, without actually having a low level of Aerobic or resistance condition; Considering the above, it is of vital importance to establish if there are validations of this test that have been adjusted to the population that trains at heights, in order to recognize them and adjust them or, on the contrary, if not, that this is the framework that invites To the standardization of these values and to make them available to the academic and sports community.http://unidadinvestigacion.usta.edu.c

A multivariate statistical process control procedure for BIAS identification in steady-state processes
In this article, a multivariate statistical process control (MSPC) strategy, devoted to bias identification and estimation for processes operating under steady-state conditions, is presented. The technique makes use of the D statistic to detect the presence of biases. Besides, it uses a new decomposition of this statistic to identify the faulty sensors. The strategy is based only on historical process data. Neither process modeling nor assumptions about the probability distribution of measurement errors are required. In contrast to methods based on fundamental models, both redundant and nonredundant measurements can be examined to identify the presence of biases. The performance of the proposed technique is evaluated using data-reconciliation benchmarks. Results indicate that the technique succeeds in identifying single and multiple biases and fulfills three paramount issues to practical implementation in commercial software: robustness, uncertainty, and efficiency. © 2008 American Institute of Chemical Engineers.Fil: Sanchez, Mabel Cristina.

Epigenetic control of epithelial-mesenchymal transition
El proceso de transición epitelio-mesénquima (TEM) permite que una célula epitelial, de manera temporal, adquiera un fenotipo mesenquimal como respuesta a un estímulo interno o externo. Este proceso se caracteriza por la activación y represión de genes involucrados en diferentes vías de señalización asociadas con migración, invasión, apoptosis, entre otros. En este
proceso, la epigenética cumple un papel fundamental, pues comprende cuatro mecanismos: metilación de ADN, modificación covalente de histonas, ARN no codificantes
(ARNnc) y complejos remodeladores de la cromatina, que regulan la expresión de un gen sin alterar su secuencia. En esta revisión de tema los autores describen los principales mecanismos epigenéticos involucrados en la regulación de
la expresión de genes que se activan y reprimen a lo largo del proceso TEM.Artículo de revisión1-22The mesenchymal epithelial transition (MET) process allows a temporary epithelial cell to acquire a mesenchymal phenotype in response to an internal or external stimulus.
This process is characterized by the activation and
repression of genes involved in different signaling pathways associated with migration, invasion and apoptosis, among others. In this process epigenetics plays a fundamental role. Epigenetics comprises four mechanisms: DNA
methylation, covalent modification of histones, noncoding RNAs (RNACs) and chromatin remodeling complexes, which regulate the expression of a gene without altering its sequence. In this topic review, the authors describe the main epigenetic mechanisms involved in the regulation of the expression of genes that are activated and repressed throughout the TEM process.https://orcid.org/0000-0003-1555-6661https://orcid.org/0000-0002-5668-0266https://orcid.org/0000-0001-8225-4394https://orcid.org/0000-0002-6563-7067https://orcid.org/0000-0003-3961-1434https://orcid.org/0000-0002-1996-813Xhttps://orcid.org/0000-0002-2891-2365https://orcid.org/0000-0001-5070-8742https://orcid.org/0000-0002-1051-6356https://orcid.org/0000-0001-5650-6471https://orcid.org/0000-0003-4492-3440https://orcid.org/0000-0002-8831-4498https://orcid.org/0000-0001-8946-5346https://orcid.org/0000-0003-3975-2835https://orcid.org/0000-0001-8528-4433Revista Nacional - Indexad
Exilio, intelectual orgánico y Filosofía de la Liberación en los escritos de Dussel (1975–1982)
El objetivo de la presente investigación consiste en reflexionar acerca de la obra Praxis Latinoamericana y Filosofía de la Liberación ([1983] 2012) de Enrique Dussel producida a partir de su experiencia exiliar mexicana. Nos concentramos específicamente en los escritos filosóficos elaborados en el periodo comprendido desde el año 1975 hasta 1982. Asimismo, nos proponemos examinar de modo episódico los tópicos de exilio, intelectual orgánico y de Filosofía de la Liberación en el periodo indicado. Nuestra óptica nos permite comprender no solo el contexto de emergencia y producción de estos escritos sino también atender a sus desplazamientos temáticos en relación a la politicidad del discurso filosófico. Para nuestro enfoque teórico–metodológico utilizamos la historia de las ideas latinoamericanas desde “ampliación metodológica” propuesta por Arturo Andrés Roig (Acosta, 2009; Arpini, 2017b, 2021b; Cerutti Guldberg, 2009; Roig, 2009, 2013c) y la concepción de Walter Benjamin del autor como un productor (Benjamin, 2004)...Fil: Sanchez, Esteban Gabriel.

Surface temperature variability in a tropical Andean summit: influence of ENSO, elevation, and slope direction
Tropical Andean ecosystems are critical for biodiversity conservation and water regulation. Climate change is affecting these ecosystems, but research at high altitudes is still scarce. We aim to understand the complex relationships between surface temperatures and seasons, El Niño Southern Oscillation phenomenon (ENSO), elevation, and slope direction, using novel in situ monitoring data in Northern South America (i.e., Cocuy National Park, Colombia). We analyzed hourly surface temperature data recorded from 2011 to 2019 at four summits between 4050 and 4400 m elevation, collected using self-logging thermometers as part of the Global Observation Research Initiative in Alpine Environments (GLORIA) Andes network. Furthermore, we assessed temperature trends and differences in relation to elevation, season, slope, and ENSO. Contrary to other regional results, surface warming in these summits did not increase with altitude i.e., no local evidence of elevation-dependent warming (EDW). Even more, minimum and maximum temperatures exhibited contrasting trends: minimum and maximum temperatures increased over time at the lowest elevation, while minima increased and maxima decreased at the highest elevation. Also, lower elevations warmed faster during the dry season. Surface temperatures were weakly correlated with the Oceanic Niño Index (ONI), and the other El Niño indices (1+2, 3 and 4). Given that the ONI index reflects both the effects of El Niño and La Niña, we observed that during La Niña there was a significant intensification of warming for minimum temperatures and cooling for maximum temperatures at the highest elevation. Slope orientation played an important role. Contrary to what other studies have found, minimum temperature trends on slopes exposed to predominant winds (i.e., northeasterlies) were significantly different (warmer) from the leeward slopes (cooler). These findings underscore the need for continued research and monitoring to better understand microclimate variability and heterogeneity in these complex topographic regions. Such efforts are essential for improving climate model accuracy and guiding effective natural resource management in the face of a changing climate
