Genesis and Coronal-jet-generating Eruption of a Solar Minifilament Captured by IRIS Slit-raster Spectra

Published: October 2022

Abstract
We present the first Mg ii slit-raster spectra from the Interface Region Imaging Spectrograph (IRIS) that fully capture the genesis and coronal-jet-generating eruption of a central-disk solar minifilament. The minifilament arose in a negative-magnetic-polarity coronal hole. The Mg ii spectroheliograms verify that the minifilament plasma temperature is chromospheric. The Mg ii spectra show that the erupting minifilament’s plasma has blueshifted upflow in the onset of the jet spire and simultaneous redshifted downflow at the location of the compact jet bright point (JBP). From the Mg ii spectra together with Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) EUV images and SDO/Helioseismic and Magnetic Imager (HMI) magnetograms, we find: (i) the minifilament forms above a flux-cancelation neutral line at an edge of a negative-polarity network flux clump; (ii) during the onset of the minifilament’s fast eruption and jet spire, the JBP begins brightening over the flux-cancelation neutral line. From IRIS2 inversion of the Mg ii spectra, the JBP’s Mg ii bright plasma has electron density, temperature, and downward (redshift) Doppler speed of 1012 cm−3, 6000 K, and 10 km s−1, respectively, and the growing spire shows clockwise spin. We speculate: (i) during the slow rise of the erupting minifilament-carrying a twisted flux rope, the top of the erupting flux-rope loop, by writhing, makes its field direction opposite to that of the encountered ambient far-reaching field; (ii) the erupting kink then can reconnect with the far-reaching field to create the spire and reconnect internally to create the JBP. We conclude that this coronal jet is normal in that magnetic flux cancelation builds a minifilament-carrying twisted flux rope and triggers the JBP-generating and jet-spire-generating eruption of the flux rope.
Detecting Magnetospheric Radio Emission from Giant Exoplanets

Published: October 2022

Abstract
As radio astronomy enters a golden age, ground-based observatories are reaching sensitivities capable of unlocking a new and exciting field of exoplanet observation. Radio observation of planetary auroral emission provides unique and complementary insight into planetary science not available via orthodox exoplanet observation techniques. Supplying the first measurements of planetary magnetic fields, rotation rates, and orbital obliquities, we gain necessary and crucial insight into our understanding of the star–planet relationships, geophysics, composition, and habitability of exoplanets. Using a stellar-wind-driven Jovian approximation, we present analytical methods for estimating magnetospheric radio emission from confirmed exoplanets. Predicted radio fluxes from cataloged exoplanets are compared against the wavelengths and sensitivities of current and future observatories. Candidate exoplanets are downselected based on the sky coverage of each ground-based observatory. Orbits of target exoplanets are modeled to account for influential orbit-dependent effects in anticipating time-varying exoplanet radio luminosity and flux. To evaluate the angular alignment of exoplanetary beamed emission relative to Earth’s position, the equatorial latitude of exoplanetary auroral emission is compared against Earth’s apparent latitude on the exoplanet. Predicted time-dependent measurements and recommended beamformed observations for ground-based radio arrays are provided, along with a detailed analysis of the anticipated emission behavior for τ Boo b.

Abstract
It has been widely recognized that the ionosphere of the terrestrial planet responds greatly to the enhanced X-ray and extreme ultraviolet radiation during solar flares. However, little attention has been paid to the comparative study of the ionospheric response between different Earth-like planets. In this work, we investigate the responses of the ionospheres of Earth, Venus, and Mars to the 2017 September 6 solar flares, with self-consistent planetary ionospheric models. The result shows that the electron density increases significantly in the relatively low ionosphere region, and its maximum relative change displays profound differences between planets. The ion temperatures at Earth and Venus share a similar response to flares, but differ from those at Mars, which relates to the background atmospheric conditions. For the electron temperature response to the X9.3 flare, at Earth it increases with a maximum magnitude of 250 K, in contrast to the decrease of ∼45 K at Venus and ∼40 K at Mars. The vertical plasma velocity at all three planets exhibits enhancement during solar flares. As a result, the upward flux increases by 2.16 × 1012 m−2 s−1 at 800 km of Earth, 3.79 × 1010 m−2 s−1, and 8.45 × 109 m−2 s−1 at 400 km of Venus and Mars. This is the first self-consistent simulation of the flare-induced enhancement of upward plasma flow at Venus and Mars.
Evidence That Shocks Destroy Small PAH Molecules in Low-luminosity Active Galactic Nuclei
Authors: Zhang Lulu , Ho Luis C. , Li Aigen 
Published: October 2022

Abstract
We combined mapping-mode mid-infrared Spitzer spectra with complementary infrared imaging to perform a spatially resolved study of polycyclic aromatic hydrocarbon (PAH) emission from the central regions of 66 nearby galaxies, roughly evenly divided into star-forming systems and low-luminosity active galactic nuclei (AGNs). In conjunction with similar measurements available for quasars, we aim to understand the physical properties of PAHs across a broad range of black hole accretion power, with the goal of identifying observational diagnostics that can be used to probe the effect of AGNs on the host galaxy. Whereas the PAH emission correlates tightly with far-ultraviolet luminosity in star-forming regions, the spatially resolved regions of AGNs tend to be PAH deficient. Moreover, AGN regions exhibit on average smaller PAH 6.2 μm/7.7 μm and larger PAH 11.3 μm/7.7 μm band ratios. Although the current data are highly restrictive, they suggest that these anomalous PAH band ratios cannot be explained by the effects of the AGN radiation field alone. Instead, they hint that small grains may be destroyed by the combined effects of radiative processes and shocks, which are plausibly linked to jets and outflows preferentially associated with highly sub-Eddington, radiatively inefficient AGNs. While quasars also present a PAH deficit and unusual PAH band ratios, their characteristics differ in detail compared to those observed in more weakly accreting AGNs, a possible indicator of fundamental differences in their modes of energy feedback.
Temperature and Differential Emission Measure Profiles in Turbulent Solar Active Region Loops
Authors: Emslie A. Gordon , Bradshaw Stephen J. 
Published: October 2022

Abstract
We examine the temperature structure of static coronal active region loops in regimes where thermal conductive transport is driven by Coulomb collisions, by turbulent scattering, or by a combination of the two. (In the last case collisional scattering dominates the heat transport at lower levels in the loop where temperatures are low and densities are high, while turbulent scattering dominates the heat transport at higher temperatures/lower densities.) Temperature profiles and their corresponding differential emission measure distributions are calculated and compared to observations, and earlier scaling laws relating the loop apex temperature and volumetric heating rate to the loop length and pressure are revisited. Results reveal very substantial changes, compared to the wholly collision-dominated case, to both the loop scaling laws and the temperature/density profiles along the loop. They also show that the well-known excess of differential emission measure at relatively low temperatures in the loop may be a consequence of the flatter temperature gradients (and so increased amount of material within a specified temperature range) that results from the predominance of turbulent scattering in the upper regions of the loop.

Abstract
NASA’s Double Asteroid Redirection Test (DART) is the first full-scale test of an asteroid deflection technology. Results from the hypervelocity kinetic impact and Earth-based observations, coupled with LICIACube and the later Hera mission, will result in measurement of the momentum transfer efficiency accurate to ∼10% and characterization of the Didymos binary system. But DART is a single experiment; how could these results be used in a future planetary defense necessity involving a different asteroid? We examine what aspects of Dimorphos’s response to kinetic impact will be constrained by DART results; how these constraints will help refine knowledge of the physical properties of asteroidal materials and predictive power of impact simulations; what information about a potential Earth impactor could be acquired before a deflection effort; and how design of a deflection mission should be informed by this understanding. We generalize the momentum enhancement factor β, showing that a particular direction-specific β will be directly determined by the DART results, and that a related direction-specific β is a figure of merit for a kinetic impact mission. The DART β determination constrains the ejecta momentum vector, which, with hydrodynamic simulations, constrains the physical properties of Dimorphos’s near-surface. In a hypothetical planetary defense exigency, extrapolating these constraints to a newly discovered asteroid will require Earth-based observations and benefit from in situ reconnaissance. We show representative predictions for momentum transfer based on different levels of reconnaissance and discuss strategic targeting to optimize the deflection and reduce the risk of a counterproductive deflection in the wrong direction.
L’approche narrative collective : conversations en échafaudage pour l’intégration identitaire des étudiants en entrepreneuriat social et durable
Authors: Solbreux Julie , Hermans Julie , Pondeville Sophie 
Published: October 2022

Cet article invite à découvrir l’approche narrative collective comme éclairage de nos pratiques d’enseignements en entrepreneuriat social et durable. L’objectif pédagogique majeur du dispositif vise à développer la capacité des étudiants à intégrer leur identité : faire du lien entre soi - son individualité complexe riche de ses valeurs et de ses intentions ; les autres - ses équipiers, dans l’échange et l’interaction des travaux de groupe ; et le reste du monde - l’environnement où s’inscrivent ses actions avec l’intention d’y produire un impact. Par l’utilisation d’histoires, de métaphores et d’objets flottants tel que le photolangage, les participants co-construisent des interprétations communes, riches et inclusives. Elles portent sur des moments d’exceptions où le groupe prend conscience et confiance en ses ressources et sa capacité à faire face aux défis sociaux et environnementaux qui l’entourent.

Integrated Art and ESP Project in Ukraine
Authors: Olizko Yuliia 
Published: October 2022

Abstract—The article describes an integrated art and English project for specific purposes on the topic “Academic Conferences” used for teaching future Ukrainian engineers in the winter of 2022. The project finished right before the war in Ukraine began. The sample size included 90 third-course future chemical engineers who study English for specific purposes. This study investigated the benefits of the project for future engineers, the role of the art practices used, as well as students’ perceptions of the project. Online questionnaires, observations and interviews were used. The results showed that the project improved students’ confidence in different conference-related skills and had a positive influence on the professional language skills development of future engineers. Art practices used in the project made learning memorable, contextualised and authentic. Art-related activities promoted professional communication and fostered the use of 21st-century skills such as cooperative, creative, critical and digital skills. The main hypothesis was supported and the project was effective due to the combination of project-based learning, art enhancement and integration, and specially chosen job-related art and ESP connections. The findings indicate an overwhelmingly positive response from the learners about this project and their interest in future art and ESP integrated projects. However, the study also revealed that students need additional support for developing XX cooperative, time management and writing skills as well as for working with authentic materials.
Callisto et Arcas, ou la maternité inaccomplie de l’ourse
Authors: Scaccuto Alessandra 
Published: October 2022

Cet article vise à étudier les intersections entre genre, animaux et animalité dans le mythe grec antique de Callisto et Arcas, tel qu’il est raconté par plusieurs textes grecs et latins, dont Ovide, qui est la source privilégiée de notre enquête. Le mythe est analysé à la lumière des représentations et des significations symboliques que les cultures grecque et romaine associaient à l’animal en question, l’ourse, et plus particulièrement à sa maternité, afin de voir si certaines des caractéristiques qui lui sont attribuées dans la zoologie ancienne peuvent offrir de nouvelles pistes de compréhension du mythe de Callisto. La plasticité habituelle des mythes anciens se mélange, en effet, à la polysémie de la figure de l’ourse-mère, donnant ainsi lieu à des versions différentes du même mythe, qui partagent tout de même une caractéristique. En effet, la mère et l’enfant sont toujours séparés : par conséquent, l’histoire de Callisto et d’Arcas se configure comme une histoire de maternité inaccomplie.
Intellectual capital and distance education: the experience of the open university of brazil in the municipality of Camaçari, Bahia

Published: October 2022

The main objective of this research is to evaluate the influence of intelectual human capital transformation, from the student´s perception, through the Open University of Brazil’s distance education in the municipality of Camaçari, which is an industrial hub in the metropolitan area of Salvador, Bahia. At this rate, education and development are closely connected, pondering previous studies where this approach is present. Meanwhile, distance education (DE) streamlines through its capillarity in several regions altering the perception and the way of transmitting knowledge. Additionaly, it enables significant changes if we relate the human capital and the field of study, considering cultural, ethical and social aspects. From a methodological point of view, descriptive research has been chosen, using qualitative inquiry. In relation to the methodological process, the Survey method research has been used. This study is justified due to the dimension in which the distance education has been widespread in Brazil and worldwide. As it is a regulated model by the superior instances of education in Brazil, and thus a more detailed one, it deserves more emphasis, once it often approaches DE, human capital and the region where it lies in. Following this understanding, studying the activities of the Open University of Brazil (OUB) in Camaçari, contributes to the perception of changes in the logic of education offer in the distance model, deployment in culture in a general scope and the perception of social freedoms in the object region of study. Hence, it is evident that the DE conducted by OUB in Camaçari gives rise to conditions for training and improving human capital taking into account its urban and social infrastructure, among other factors that combined, foster fertile ground to mitigate the social asymmetries while expanding individual freedoms and the progress of the region.

Fake Node Attacks on Graph Convolutional Networks
Authors: Wang Xiaoyun , Cheng Minhao , Eaton Joe , Hsieh Cho-Jui , Wu S. Felix 
Published: October 2022

In this paper, we study the robustness of graph convolutional networks (GCNs). Previous works have shown that GCNs are vulnerable to adversarial perturbation on adjacency or feature matrices of existing nodes; however, such attacks are usually unrealistic in real applications. For instance, in social network applications, the attacker will need to hack into either the client or server to change existing links or features. In this paper, we propose a new type of “fake node attacks” to attack GCNs by adding malicious fake nodes. This is much more realistic than previous attacks; in social network applications, the attacker only needs to register a set of fake accounts and link to existing ones. To conduct fake node attacks, a greedy algorithm is proposed to generate edges of malicious nodes and their corresponding features aiming to minimize the classification accuracy on the target nodes. In addition, we introduce a discriminator to classify malicious nodes from real nodes and propose a Greedy-generative adversarial network attack to simultaneously update the discriminator and the attacker, to make malicious nodes indistinguishable from the real ones. Our non-targeted attack decreases the accuracy of GCN down to 0.03, and our targeted attack reaches a success rate of 78% on a group of 100 nodes and 90% on average for attacking a single target node.

Reivindicando el Urbanismo (a pesar de todo…)
Authors: Font Arellano Antonio 
Published: October 2022

El presente artículo, con origen en el discurso de investidura de su autor como DHC por la UPV en la pasada primavera, tiene como objetivo realizar una reflexión sobre la transcendencia social del Urbanismo y reivindicar su necesaria renovación. Tras tratar de definir su naturaleza disciplinar, y apuntar sus orígenes y maneras propias de aproximarse a su objeto de estudio e intervención, a través de la historia urbana se constata su incidencia material en nuestras ciudades y territorios, y su indiscutible trascendencia cultural, política, económica y social. Se consideran los cambios en los procesos productivos y en los avances tecnológicos ocurridos desde la crisis económica de mediados de los años 70 del pasado siglo y durante el proceso de globalización, como los principales motivos de la emergencia de un nuevo modelo de ciudad, de nuevas dinámicas territoriales y de nuevos comportamientos sociales, con relevantes consecuencias en el uso y configuración del espacio urbano y territorial- agravadas por la reciente pandemia- que caracterizan la actual situación, llegando a poner en duda algunos de los principios tradicionales de la disciplina y enmarcando la presente crisis del Urbanismo. Ello plantea la actual necesidad de repensar nuestra disciplina desde la diversidad de situaciones, la creciente complejidad de los procesos y la incertidumbre del futuro, en el marco de una bien entendida transdisciplinariedad, pero sin abandonar o minusvalorar la relevante dimensión física propia del Urbanismo. Finalmente, se apuntan algunas de las principales cuestiones actuales para su renovación, como instrumento de gobierno y administración racional y democrática de la ciudad y el territorio, para el positivo progreso de nuestra sociedad.
