Intrusiones cuánticas en educación
Authors: Giraldo Jairo 
Published: November 2019

La palabra quantum es una alegoría tomada del latín. A partir de 1900, cuando fue empleada por primera vez en física, la idea tomó cuerpo y después de un cuarto de siglo dio lugar a la teoría más fundamental de las ciencias naturales. El presente texto busca convencer al lector de que el término, trasladado al ámbito educativo, puede tener efectos igualmente revolucionarios, más allá de aquellos que son obvios, derivados de las aplicaciones de esa teoría en las TIC (tecnologías de la información y la comunicación).

Por otra parte, el recurso de las TIC no puede convertirse en sustituto de la educación; bien manejadas, deben servir al propósito de potenciar capacidades cognitivas, afectivas y ejecutivas que desarrollen talento, ingenio y creatividad (TIC), tres características latentes en la inteligencia humana desde la infancia que pueden perderse si el maestro no utiliza las estrategias pedagógicas y metodológicas apropiadas. Así, se considera que la alegoría de los efectos cuánticos, en particular los de superposición, tunelamiento y entrelazamiento, de difícil observación en el mundo cotidiano, llevada al extremo en el caso de las motivaciones, emociones y afectos, puede ser un buen punto de partida para generar un nuevo paradigma educativo. Por último, se trabajará el papel de algunas de las denominadas tecnologías emergentes NBIC en la educación.

Abstract
We performed time-resolved spectroscopy on a sample of 38 single pulses from 37 gamma-ray bursts detected by the Fermi/Gamma-ray Burst Monitor during the first 9 yr of its mission. For the first time a fully Bayesian approach is applied. A total of 577 spectra are obtained and their properties studied using two empirical photon models, namely the cutoff power law (CPL) and Band model. We present the obtained parameter distributions, spectral evolution properties, and parameter relations. We also provide the result files containing this information for usage in further studies. It is found that the CPL model is the preferred model, based on the deviance information criterion and the fact that it consistently provides constrained posterior density maps. In contrast to previous works, the high-energy power-law index of the Band model, β, has in general a lower value for the single pulses in this work. In particular, we investigate the individual spectrum in each pulse, that has the largest value of the low-energy spectral indexes, α. For these 38 spectra, we find that 60% of the α values are larger than −2/3, and thus incompatible with synchrotron emission. Finally, we find that the parameter relations show a variety of behaviors. Most noteworthy is the fact that the relation between α and the energy flux is similar for most of the pulses, independent of any evolution of the other parameters.

Abstract
We have conducted ALMA CO isotopes and 1.3 mm continuum observations toward filamentary molecular clouds of the N159W-South region in the Large Magellanic Cloud with an angular resolution of ∼0.″25 (∼0.07 pc). Although the previous lower-resolution (∼1″) ALMA observations revealed that there is a high-mass protostellar object at an intersection of two line-shaped filaments in 13CO with the length scale of ∼10 pc, the spatially resolved observations, in particular, toward the highest column density part traced by the 1.3 mm continuum emission, the N159W-South clump, show complicated hub-filamentary structures. We also discovered that there are multiple protostellar sources with bipolar outflows along the massive filament. The redshifted/blueshifted components of the 13CO emission around the massive filaments/protostars have complementary distributions, which is considered to be possible evidence for a cloud–cloud collision. We propose a new scenario in which the supersonically colliding gas flow triggers the formation of both the massive filament and protostars. This is a modification of the earlier scenario of cloud–cloud collision, by Fukui et al., that postulated the two filamentary clouds occur prior to the high-mass star formation. A recent theoretical study of the shock compression in colliding molecular flows by Inoue et al. demonstrates that the formation of filaments with hub structure is a usual outcome of the collision, lending support for the present scenario. The theory argues that the filaments are formed as dense parts in a shock compressed sheet-like layer, which resembles “an umbrella with pokes.”

Abstract
We report the discovery of a unique collection of metal-poor giant stars that exhibit anomalously high levels of 28Si, clearly above typical Galactic levels. Our sample spans a narrow range of metallicities, peaking at −1.07 ± 0.06, and exhibits abundance ratios of [Si, Al/Fe] that are as extreme as those observed in Galactic globular clusters (GCs), and Mg is slightly less overabundant. In almost all the sources we used, the elemental abundances were redetermined from high-resolution spectra, which were reanalyzed assuming LTE. Thus, we compiled the main element families, namely, the light elements (C, N), α-elements (O, Mg, Si), iron-peak element (Fe), s-process elements (Ce, Nd), and the light odd-Z element (Al). We also provide dynamical evidence that most of these stars lie on tight (inner) halo-like and retrograde orbits passing through the bulge. Such kinds of objects have been found in present-day halo GCs, providing the clearest chemical signature of past accretion events in the (inner) stellar halo of the galaxy, possibly formed as the result of dissolved halo GCs. Their chemical composition is, in general, similar to that of typical GC populations, although several differences exist.

Ce texte est la retranscription d’une conversation entre Léandro de Lajonquière et Ilaria Pirone sur la place de la psychanalyse dans le champ de l’enfance et de l’éducation. Après avoir mis en perspective les différences entre les développements latino-américains et français en la matière, l’échange porte sur la singularité de la réflexion de Maud Mannoni et de la création de l’École expérimentale de Bonneuil. Les auteurs discutent alors du rapport actuel à l’enfant à partir de la thèse que l’idéal imaginaire contemporain est occupé par une figure fictionnelle exclue du « sentiment d’enfance » dont parlait Philippe Ariès, l’enfant autiste. La conversation se termine sur la question de la place symbolique de l’école, et du maître dans la vie d’un enfant.
HEp-2 CELL CLASSIFICATION BY ADAPTIVE CONVOLUTIONAL LAYER BASED CONVOLUTIONAL NEURAL NETWORK
Authors: Manju C. C. , Jose M. Victor 
Published: November 2019

Objective: The antinuclear antibodies (ANA) that present in the human serum have a link with various autoimmune diseases. Human Epithelial type-2 (HEp-2) cells acts as a substance in the Indirect Immuno fluorescence (IIF) test for diagnosing these autoimmune diseases. In recent times, the computer-aided diagnosis of autoimmune diseases by the HEp-2 cell classification has drawn more interest. Though, they often pose limitations like large intra-class and small inter-class variations. Hence, various efforts have been performed to automate the procedure of HEp-2 cell classification. To overcome these problems, this research work intends to propose a new HEp-2 classification process. Materials and Methods: This is regulated by integrating two processes, namely, segmentation and classification. Initially, the segmentation of the HEp-2 cells is carried out by deploying the morphological operations. In this paper, two morphology operations are deployed called opening and closing. Further, the classification process is exploited by proposing a modified Convolutional Neural Network (CNN). The main objective is to classify the HEp-2 cells effectively (Centromere, Golgi, Homogeneous, Nucleolar, NuMem, and Speckled) and is made by exploiting the optimization concept. This is implanted by developing a new algorithm called Distance Sorting Lion Algorithm (DSLA), which selects the optimal convolutional layer in CNN. Results: Through the performance analysis, the performance of the proposed model for test case 1 at learning percentage 60 is 3.84%, 1.79%, 6.22%, 1.69%, and 5.53% better than PSO, FF, GWO, WOA, and LA, respectively. At 80, the performance of the proposed model is 5.77%, 6.46%, 3.95%, 3.24%, and 5.55% better from PSO, FF, GWO, WOA, and LA, respectively. Hence, the performance of the proposed work is proved over other models under different measures. Conclusion: Finally, the performance is evaluated by comparing it with the other conventional algorithms in terms of accuracy, sensitivity, specificity, precision, FPR, FNR, NPV, MCC, F1-Score and FDR, and proves the efficacy of the proposed model.
Patrones de desplazamiento del eje instantáneo de rotación del movimiento de elevación humeral
Authors: Page Álvaro Felipe , Cáceres Cáceres Magda Liliana 
Published: November 2019

En este trabajo se presentan los resultados de un estudio experimental para la descripción de las trayectorias descritas por el eje instantáneo de rotación (EIR) toracohumeral para movimientos cíclicos de elevación-descenso. Se ha desarrollado una técnica de análisis de movimientos mediante videofotogrametría que permite la medida del EIR del movimiento relativo húmero tórax con un error inferior a 1 cm y de forma muy reproducible [1,2]. Esto permite registrar el movimiento continuo del EIR como un axoide, cuyo desplazamiento mediolateral está relacionado con las velocidades de rotación de las articulaciones esternoclavicular, acromioclavicular y glenohumeral, y cuya posición vertical se asocia a la elevación de articulación glenohumeral [3] Se ha realizado un estudio con 45 sujetos sanos y 15 sujetos con patologías del hombro, analizando el movimiento cíclico de elevación-descenso del húmero en los planos frontal y escapular. La ubicación y forma de los axoides es sensible a los efectos de la carga y del estado funcional del sujeto. Así el efecto de la carga se manifiesta en un desplazamiento medial de la trayectoria del EIR, asociado a un movimiento más acusado de las articulaciones esternoclavicular, acromioclavicular frente al movimiento sin carga. Por otra parte, el efecto de la patología afecta a la trayectoria del EIR sólo a partir de cierto nivel de limitación funcional. Los patrones correspondientes a pacientes con limitaciones leves no muestran diferencias importantes frente a los sujetos sanos. Los resultados obtenidos muestran que el EIR puede ser de utilidad en la valoración funcional biomecánica del hombro, al ofrecer información sobre la coordinación de las diferentes articulaciones que lo constituyen REFERENCIAS [1] A.Page, J.A.

Abstract. In global hydrological models, groundwater storages and flows are generally simulated by linear reservoir models. Recently, the first global gradient-based groundwater models were developed in order to improve the representation of groundwater–surface-water interactions, capillary rise, lateral flows, and human water use impacts. However, the reliability of model outputs is limited by a lack of data and by uncertain model assumptions that are necessary due to the coarse spatial resolution.
The impact of data quality is presented in this study by showing the sensitivity of a groundwater model to changes in the only available global hydraulic conductivity dataset. To better understand the sensitivity of model output to uncertain spatially distributed parameters, we present the first application of a global sensitivity method for a global-scale groundwater model using nearly 2000 steady-state model runs of the global gradient-based groundwater model G3M. By applying the Morris method in a novel domain decomposition approach that identifies global hydrological response units, spatially distributed parameter sensitivities are determined for a computationally expensive model. Results indicate that globally simulated hydraulic heads are equally sensitive to hydraulic conductivity, groundwater recharge, and surface water body elevation, though parameter sensitivities vary regionally. For large areas of the globe, rivers are simulated to be either losing or gaining, depending on the parameter combination, indicating a high uncertainty in simulating the direction of flow between the two compartments. Mountainous and dry regions show a high variance in simulated head due to numerical instabilities of the model, limiting the reliability of computed sensitivities in these regions. This is likely caused by the uncertainty in surface water body elevation. We conclude that maps of spatially distributed sensitivities can help to understand the complex behavior of models that incorporate data with varying spatial uncertainties. The findings support the selection of possible calibration parameters and help to anticipate challenges for a transient coupling of the model.

De kwaliteit van beleidsdoorlichtingen
Voor doeltreffend en doelmatig beleid is het essentieel om verantwoording af te leggen over de gemaakte keuzes en te leren van de lessen uit het verleden. Om dit te stimuleren verplicht de Regeling Periodiek Evaluatieonderzoek (RPE) de rijksoverheid om periodiek beleidsdoorlichtingen te (laten) verrichten. Een beleidsdoorlichting bundelt alle beschikbare kennis over de doeltreffendheid en doelmatigheid van een volledig beleidsterrein over een bepaalde periode. Daartoe worden alle tussentijds uitgevoerde beleidsevaluaties bestudeerd.Dit artikel beschrijft de kwaliteit van beleidsdoorlichtingen. Het artikel is gebaseerd op onderzoek van SEO Economisch Onderzoek in opdracht van het Ministerie van Financiën. Het gebruik van beleidsdoorlichtingen valt buiten de scope van dit artikel.Uit een steekproef van 49 beleidsdoorlichtingen blijkt dat de doeltreffendheid en doelmatigheid van het gevoerd beleid vaak niet goed in beeld komen. Dit komt onder meer omdat er te weinig goed evaluatieonderzoek wordt uitgevoerd en omdat beleidsdoelstellingen met enige regelmaat worden aangepast. Het gevolg hiervan is dat uitspraken over de doeltreffendheid van beleid meestal niet stevig onderbouwd zijn en de doelmatigheid van beleid onderbelicht blijft. Dit maakt het minder goed mogelijk om lessen uit het verleden te trekken.Er is ruimte voor verbetering. Zo kan (1) het lerend vermogen van ministeries intern versterkt worden, (2) kunnen departementen hun beleidsevaluaties systematischer uitvoeren om volledigheid te waarborgen, (3) dient er ex ante te worden vastgesteld hoe de doeltreffendheid en doelmatigheid van beleidsmaatregelen ex post (causaal) kunnen worden geëvalueerd, (4) kan de onafhankelijk deskundige die bij beleidsdoorlichtingen wordt ingezet tevens de kwaliteit van het beschikbare evaluatiemateriaal vaststellen, en (5) kan worden overwogen om beleidsdoorlichtingen strategisch te plannen aan het eind van een kabinetsperiode. Op deze manier neemt de toegevoegde waarde van de beleidsdoorlichting toe.

BackgroundTerrestrial ecosystems play a significant role in carbon (C) storage. Human activities, such as urbanization, infrastructure, and land use change, can reduce significantly the C stored in the soil. The aim of this research was to measure the spatial variability of soil organic C (SOC) in the national park La Malinche (NPLM) in the central highlands of Mexico as an example of highland ecosystems and to determine the impact of land use change on the SOC stocks through deterministic and geostatistical geographic information system (GIS) based methods.MethodsThe soil was collected from different landscapes, that is, pine, fir, oak and mixed forests, natural grassland, moor and arable land, and organic C content determined. Different GIS-based deterministic (inverse distance weighting, local polynomial interpolation and radial basis function) and geostatistical interpolation techniques (ordinary kriging, cokriging and empirical Bayes kriging) were used to map the SOC stocks and other environmental variables of the top soil layer.ResultsAll interpolation GIS-based methods described the spatial distribution of SOC of the NPLM satisfactorily. The total SOC stock of the NPLM was 2.45 Tg C with 85.3% in the forest (1.26 Tg C in the A horizon and 0.83 Tg C in the O horizon), 11.4% in the arable soil (0.23 Tg in the A horizon and only 0.05 Tg C in the O horizon) and 3.3% in the high moor (0.07 Tg C in the A horizon and <0.01 Tg C in the O horizon). The estimated total SOC stock in a preserved part of the forest in NPLM was 4.98 Tg C in 1938 and has nearly halved since then. Continuing this trend of converting all the remaining forest to arable land will decrease the total SOC stock to 0.52 Tg C.DiscussionDifferent factors explain the large variations in SOC stocks found in this study but the change in land use (conversion of forests into agricultural lands) was the major reason for the reduction of the SOC stocks in the high mountain ecosystem of the NPLM. Large amounts of C, however, could be stored potentially in this ecosystem if the area was used more sustainable. The information derived from this study could be used to recommend strategies to reverse the SOC loss in NPLM and other high-altitude temperate forests and sequester larger quantities of C. This research can serve as a reference for the analysis of SOC distribution in similar mountain ecosystems in central part of Mexico and in other parts of the world.
