The 1730 Great Metropolitan Chile Earthquake and Tsunami Commemoration: Joint Efforts to Increase the Country’s Awareness
On 8 July 1730, a great earthquake struck metropolitan Chile, causing extensive damage 1000 km along the country and focused in Valparaíso. Due to the date of occurrence of this event, large uncertainties about the ... -
A comprehensive comparison between shortest-path HARP refinement, SinMod, and DENSEanalysis processing tools applied to CSPAMM and DENSE images
(Elsevier, 2021)We addressed comprehensively the performance of Shortest-Path HARP Refinement (SP-HR), SinMod, and DENSEanalysis using 2D slices of synthetic CSPAMM and DENSE images with realistic contrasts obtained from 3D phantoms. The ... -
A Descriptive Analysis for a Collaborative Work Process: A Complex Real Medical Case in the Radiological Field
(American Scientific Publishers, 2021)Collaborative acts occur daily in every human activity. In the case of medicine, and particularly in the diagnostic decision process, these acts are very frequent and occur naturally. It is very important to properly ... -
A Feature-Based Analysis for Time-Series Classification of COVID-19 Incidence in Chile: A Case Study
(MDPI, 2021)The 2019 Coronavirus disease (COVID-19) pandemic is a current challenge for the world’s health systems aiming to control this disease. From an epidemiological point of view, the control of the incidence of this disease ... -
A Fuzzy Inference System for Management Control Tools
(MDPI, 2021)Despite the importance of the role of small and medium enterprises (SMEs) in developing and growing economies, little is known regarding the use of management control tools in them. In management control in SMEs, a holistic ... -
A Generalization of the Importance of Vertices for an Undirected Weighted Graph
(MDPI, 2021)Establishing a node importance ranking is a problem that has attracted the attention of many researchers in recent decades. For unweighted networks where the edges do not have any attached weight, many proposals have been ... -
A Generation 1.5 Palestinian Diaspora Child Refugee in Chile
(Taylor & Francis, 2021)This study follows a former child refugee’s experience of family resettlement in Chile. Born into the Palestinian Iraqi community further imperiled by the 2003 invasion of Iraq, his family fled first to the Al-Tanf refugee ... -
A hybrid model of viscous and Chaplygin gas to tackle the Universe acceleration
(Springer, 2021)Motivated by two seminal models proposed to explain the Universe acceleration, this paper is devoted to study a hybrid model which is constructed through a generalized Chaplygin gas with the addition of a bulk viscosity. ... -
A Knowledge-Based Hybrid Approach on Particle Swarm Optimization Using Hidden Markov Models
(MDPI, 2021)Bio-inspired computing is an engaging area of artificial intelligence which studies how natural phenomena provide a rich source of inspiration in the design of smart procedures able to become powerful algorithms. Many of ... -
A Learning Analytics Framework to Analyze Corporal Postures in Students Presentations
(MDPI, 2021)Communicating in social and public environments are considered professional skills that can strongly influence career development. Therefore, it is important to proper train and evaluate students in this kind of abilities ... -
A massive open cluster hiding in full sight
(Royal Astronomical Society, 2021)Obscuration and confusion conspire to limit our knowledge of the inner MilkyWay. Even atmoderate distances, the identification of stellar systems becomes compounded by the extremely high density of background sources. Here, ... -
A modeling and simulation platform for space-based compartmental modeling of pandemic spread
(IEEE, 2021)The COVID-19 outbreak has shown that Modeling and Simulation (M&S) methodologies are an important aspect to study the spread of the disease and assess the effect of different measures to diminish its negative effect. ... -
A multi-objective linear threshold influence spread model solved by swarm intelligence-based methods
(Elsevier, 2021)The influence maximization problem (IMP) is one of the most important topics in social network analysis. It consists of finding the smallest seed of users that maximizes the influence spread in a social network. The main ... -
A Multisubcellular Compartment Model of AMPA Receptor Trafficking for Neuromodulation of Hebbian Synaptic Plasticity
(Frontiers, 2021)Neuromodulation can profoundly impact the gain and polarity of postsynaptic changes in Hebbian synaptic plasticity. An emerging pattern observed in multiple central synapses is a pull–push type of control in which activation ... -
A near-infrared interferometric survey of debris-disk stars VII. The hot-to-warm dust connection
(European Southern Observatory (ESO), 2021)Context. Hot exozodiacal dust has been shown to be present in the innermost regions of an increasing number of main sequence stars over the past 15 yr. However, the origin of hot exozodiacal dust and its connection with ... -
A novel artificial autonomous system for supporting investment decisions using a Big Five model approach
(Elsevier, 2021)This paper presents the design of an artificial autonomous system (called AAS) for the stock market domain that considers an approximation from the Big Five model, which proposes that the personality of an individual belongs ... -
A physiologic rise in cytoplasmic calcium ion signal increases pannexin1 channel activity via a C-terminus phosphorylation by CaMKII
(National Academy Of Science, 2021)Pannexin1 (Panx1) channels are ubiquitously expressed in vertebrate cells and are widely accepted as adenosine triphosphate (ATP)-releasing membrane channels. Activation of Panx1 has been associated with phosphorylation ... -
