Abstract
We present an analysis of the optical properties of three Ultra Luminous X-ray (ULX) sources identified in NGC 925. We use Integral field unit data from the George Mitchel spectrograph in the context of the Metal-THINGS survey. The optical properties for ULX-1 and ULX-3 are presented, while the spaxel associated with ULX-2 had a low S/N, which prevented its analysis. We also report the kinematics and dimensions of the optical nebula associated with each ULX using ancillary data from the PUMA Fabry–Perot spectrograph. A BPT analysis demonstrates that most spaxels in NGC 925 are dominated by star-forming regions, including those associated with ULX-1 and ULX-3. Using the resolved gas-phase metallicities, a negative metallicity gradient is found, consistent with previous results for spiral galaxies, while the ionization parameter tends to increase radially throughout the galaxy. Interestingly, ULX-1 shows a very low gas metallicity for its galactocentric distance, identified by two independent methods, while exhibiting a typical ionization. We find that such low gas metallicity is best explained in the context of the high-mass X-ray binary population, where the low-metallicity environment favors active Roche lobe overflows that can drive much higher accretion rates. An alternative scenario invoking accretion of a low-mass galaxy is not supported by the data in this region. Finally, ULX-3 shows both a high metallicity and ionization parameter, which is consistent with the progenitor being a highly accreting neutron star within an evolved stellar population region.

Authors: Goodarzi Hadis , Mehrabi Ahmad , G. Khosroshahi Habib , He Han 
Published: January 2021

Abstract
We present an investigation of the magnetic activity and flare characteristics of the subgiant stars mostly from F and G spectral types and compare the results with the main-sequence (MS) stars. The light curve of 352 stars on the subgiant branch (SGB) from the Kepler mission is analyzed in order to infer stability, relative coverage, and contrast of the magnetic structures and also flare properties using three flare indexes. The results show the following. (i) Relative coverage and contrast of the magnetic features along with rate, power, and magnitude of flares increase on the SGB due to the deepening of the convective zone and more vigorous magnetic field production. (ii) Magnetic activity of the F- and G-type stars on the SGB does not show dependency on the rotation rate and does not obey the saturation regime. This is the opposite of what we saw for the MS, in which the G-, K-, and M-type stars show clear dependency on the Rossby number. (iii) The positive relationship between the magnetic features’ stability and their relative coverage and contrast remains true on the SGB; though, it has a lower dependency coefficient in comparison with the MS. (iv) Magnetic proxies and flare indexes of the SGB stars increase with increasing relative mass of the convective zone.
Disks as Inhomogeneous, Anisotropic Gaussian Random Fields

Published: January 2021

Abstract
We model astrophysical disk surface brightness fluctuations as an inhomogeneous, anisotropic, time-dependent Gaussian random field. The field locally obeys the stochastic partial differential equation of a Matérn field, which has a power spectrum that is flat at large scales and falls off as a power law at small scales. We provide a series of pedagogical examples and along the way provide a convenient parameterization for the local covariance. We then consider two applications to disks. In the first we generate an animation of a disk. In the second, by integrating over an animation of a disk, we generate synthetic light curves and show that the high frequency slope of the resulting power spectrum depends on the local covariance model. We finish with a summary and a brief discussion of other possible astrophysical applications.

Academic achievement is the achievement of all student degrees. Academic achievement in the field of academic education, is a special level of acquisition or results of academic work skills that are assessed by teachers, through standardized tests, or through a combination of both (Chaplin, 2001). For a child, learning something interesting for him will be easier to be accepted and understood. In terms of interest, someone who has an interest in a field will be easy in studying the field. Based on this interest, the counseling teacher can use group guidance services with my practice techniques to be responsible for motivating and feeling confident in improving their academic performance.

Bagi seorang anak, mempelajari sesuatu hal yang menarik bagi dirinya akan lebih mudah untuk diterima dan dipahami. Dalam hal minat, seseorang yang menaruh minat pada suatu bidang akan mudah dalam mempelajari bidang tersebut. Dengan berdasarkan minat tersebut guru bimbingan konseling bisa menggunakan layanan bimbingan kelompok dengan teknik latihan saya bertanggung jawab untuk memotivasi dan merasa percaya diri dalam meningkatkan prestasi akademiknya.
UPDATE: Should Hydroxychloroquine (HCQ) or Chloroquine (CQ) be used in the treatment of COVID-19?
Authors: Palileo-Villanueva Lia M. , Uy Elenore Judy B. 
Published: January 2021

KEY FINDINGS
There is insufficient evidence to support the routine use of HCQ or CQ for the treatment of COVID-19. Results
from interim analyses of 2 large RCTs, the Recovery and the Solidarity trials, reportedly showed no clinical benefit
from HCQ for hospitalized patients with COVID-19.

There are 3 randomized controlled trials that investigated the efficacy and safety of HCQ compared to standard

therapy. Overall quality of evidence was very low.

Meta-analyses from the “COVID-19 Living Data” project suggests that the use of HCQ may increase the

incidence of adverse events at day 14 to day 28 (RR 2.49, 95% confidence interval: 1.04 to 5.98, moderate
quality of evidence); the most common adverse event across the two trials is diarrhea (n=8).

In a statement dated June 5, 2020, the investigators of the Recovery trial announced their decision to halt

further enrollment to the HCQ arm of the trial because an interim analysis showed no clinical benefit from
the use of HCQ in hospitalized patients with COVID.

On June 15, 2020, the US FDA revoked the emergency use authorization for HCQ and CQ as treatment for

COVID-19.

On June 18, 2020, the WHO announced that recruitment to the HCQ arm of the Solidarity trial has been halted.
Post Post-Truth: Epistemologies of Disintegration and the Praxeology of Truth
Authors: Kleeberg Bernhard 
Published: January 2021

Our truth culture has changed. Yet we are not living in a post-truth era but in a truth era – an observation of the ongoing debates shows a proliferation of invocations of truth. This paper argues that in order to grasp this transition, we should not refer to classical truth theories or common oppositions such as knowledge and belief, objectivity and subjectivity. Instead, we should focus on concrete practices in concrete situations: on “doing truth.” This paper introduces the concept of a “praxeology of truth,” which sets out to analyse truth by means of two parameters: “truth scenes” and “truth figures.” In suggesting that to ask about truth is to pose the question of power, it follows Michel Foucault, but it regards the invocation of truth as a technique of identity politics and truth as a social operator.
Using multiple methods to investigate the effects of land-use changes on groundwater recharge in a semi-arid area
Authors: Barua Shovon , Cartwright Ian , Dresel P. Evan , Daly Edoardo 
Published: January 2021

Abstract. Understanding the applicability and uncertainties of methods for documenting recharge rates in semi-arid areas is important for assessing the successive effects of land-use changes and understanding groundwater systems. This study focuses on estimating groundwater recharge rates and understanding the impacts of land-use changes on recharge rates in a semi-arid area in southeast Australia. Two adjacent catchments were cleared ∼180 years ago following European settlement, and a eucalypt plantation forest was subsequently established ∼15 years ago in one of the catchments. Chloride mass balance analysis yields recharge rates of 0.2 to 61.6 mm yr−1 (typically up to 11.2 mm yr−1). The lower of these values probably represents recharge rates prior to land clearing, whereas the higher likely reflects recharge rates following the initial land clearing. The low pre-land-clearing recharge rates are consistent with the presence of old groundwater (residence times up to 24 700 years) and the moderate-to-low hydraulic conductivities (0.31 to 0.002 m d−1) of the aquifers. Recharge rates estimated from tritium activities and water table fluctuations reflect those following the initial land clearing. Recharge rates estimated using water table fluctuations (15 to 500 mm yr−1) are significantly higher than those estimated using tritium renewal rates (0.01 to 89 mm yr−1; typically <14.0 mm yr−1) and approach the long-term average annual rainfall (∼640 mm yr−1). These recharge rates are unrealistic given the estimated evapotranspiration rates of 500 to 600 mm yr−1 and the preservation of old groundwater in the catchments. It is likely that uncertainties in the specific yield results in the water table fluctuation method significantly overestimating recharge rates, and despite the land-use changes, the present-day recharge rates are relatively modest. These results are ultimately important for assessing the impacts of land-use changes and management of groundwater resources in semi-arid regions in Australia and elsewhere.
Alteration Mineralogy of the Zhengguang Epithermal Au-Zn Deposit, Northeast China: Interpretation of Shortwave Infrared Analyses During Mineral Exploration and Assessment
Authors: Wang Le , Percival Jeanne B. , Hedenquist Jeffrey W. , Hattori Keiko , Qin Kezhang 
Published: January 2021

Abstract
Alteration mineralogy from shortwave infrared (SWIR) spectroscopy was compared with X-ray diffraction (XRD) analyses for samples from the Zhengguang intermediate sulfidation epithermal Au-Zn deposit, eastern Central Asian orogenic belt, northeast China. The SWIR and XRD analyses indicate that alteration minerals in the vein-adjacent halo mainly comprise quartz, illite, and locally pyrite (QIP) and chlorite, whereas samples from the pervasive propylitic alteration of host basaltic andesite lava contain epidote, chlorite, carbonate, montmorillonite, and locally illite. SWIR mineral identifications from automated mineral identification software may not always be accurate; thus, the results should be validated by the user. The wavelength position of the Al-OH (~2,200 nm; wAlOH) absorption feature can be used to approximate the composition of illite or white mica. However, caution is required when using the wAlOH value to assess paleotemperatures, as the composition of illite can be influenced by the composition of the host rocks or the hydrothermal fluid. In addition, values of the illite spectral maturity (ISM; ratio of the depth of the ~2,200 nm minima divided by the ~1,900 nm minima) can be affected by the presence of other hydrous minerals, quartz-sulfide veins, and absorption intensity (which can be a function of rock coloration). Despite these cautions, the spatial distribution and variation of the wAlOH and ISM values for illite suggest that the high paleotemperature hydrothermal upflow zones related to the Zhengguang Au-Zn deposit were located below ore zones I and IV, which are predicted to be proximal to the intrusive center of the system.

Max Stirner y la política de la insurrección
Authors: D'Angelo Valerio 
Published: January 2021

En este artículo se quiere trazar una teoría política de la insurrección en el pensamiento de Max Stirner, en tanto alternativa ética y política a la revolución. Se mostrará cómo, según el pensador alemán, la revolución es en última instancia una estrategia fallida de emancipación en tanto en cuanto no libera al individuo de las formas de subjetividad que lo mantienen dependiente del poder. Más en general, se enseñará como el orden liberal post-revolucionario, detrás del lenguaje secular de los derechos, las libertades y la igualdad, engendra técnicas más sutiles de gobernabilidad del individuo. La insurrección, en cambio, puede ser vista como un rechazo de las identidades y de los roles que disciplinan al individuo. Al respecto, se prestará una atención especial al concepto stirneriano de Eigenheit (propiedad de sí), como estrategia ética de auto-determinación y liberación de las formas rígidas de la subjetividad. En última instancia, se querrá mostrar cómo todo el proyecto político de la insurrección stirneriana se basa en un anarquismo ontológico que rechaza la lógica teleocrática del racionalismo moderno y pone en entredicho la misma noción de realización.
The aim of this article to outline a political theory of insurrection in Max Stirner’s thought as an ethical and political alternative to revolution. I will show that revolution is ultimately a failed strategy of emancipation as it does not free the individual from the forms of subjectivity that keep her dependent on power. Insurrection, on the other hand, can be seen as a rejection of the identities and roles that discipline the individual. In this regard, special attention will be paid to the Stirnerian concept of Eigenheit as an ethical strategy of self-determination and liberation from rigid forms of subjectivity. Ultimately, I will show how the whole political project of the Stirnerian insurrection is based on an ontological anarchism that rejects the teleocratic logic of modern rationalism and calls into question the very notion of realization.
« Une femme sans patrie » à la polonaise
Authors: Szczur Przemyslaw 
Published: January 2021

The article discusses the hypertextual relations between Stanislas Dotremont’s La Polonaise and Benjamin Constant’s Adolphe, focusing on the rewriting of the main feminine character: Ellénore/Ellen. The adopted perspective is inspired by narratology, gender studies and imagology. It makes it possible to note some changes, the main ones consisting of a transvocalization and transfocalization of the narration and a transvalorization and transmotivation of the character. Rewriting also leads to an accentuation of the axiological, ideological and historical dimensions of the narrative. However, the impact of these modifications is, after all, relatively limited, which is why the Dotremontian rewriting enterprise can be described as neo-classical.
L’article constitue une analyse des relations hypertextuelles entre La Polonaise de Stanislas Dotremont et Adolphe de Benjamin Constant, focalisée sur la réécriture du principal personnage féminin : Ellénore/Ellen. La perspective adoptée s’inspire de la narratologie classique, des études de genre et de l’imagologie. Elle permet de relever quelques changements dont les principaux consistent en une transvocalisation et transfocalisation de la narration et une transvalorisation et transmotivation de l’héroïne. La réécriture mène aussi à une accentuation des dimensions axiologique, idéologique et historique du récit. L’impact de ces modifications est cependant, somme toute, relativement limité, c’est pourquoi l’entreprise de réécriture dotremontienne peut être qualifiée de néo-classique.
Bove dans le labyrinthe: une lecture du Piège
Authors: Macho Vargas Azucena 
Published: January 2021

The rediscovery of Emmanuel Bove from the 1980s onwards drew attention above all to his early works, notably Mes amis. However, the novels published after the war, far from the subjects dear to the author, remain less famous. The reading of The Trap is used to show that, without abandoning his style and his way of looking at the world and describing it, Bove succeeds in immersing us into the dark universe of the Occupation. We thus witness the failure of the Bove anti-hero who for once is acting yet setting himself too ambitious a goal, and while trying to defeat the occupying monster he perishes in the occupied France labyrinth. Moreover, the labyrinth as a formal structure becomes a recurring element in the novel.
La redécouverte d’Emmanuel Bove à partir des années 80 a surtout attiré l’attention sur ses premières œuvres, notamment Mes amis. Toutefois les romans publiés après la guerre, éloignés des sujets chers à l’auteur, restent moins connus. La lecture du Piège sert à montrer que, sans abandonner son style et sa manière de voir le monde et le décrire, Bove réussit á nous plonger dans l’univers gris de l’Occupation, On assiste donc à l’échec de l’anti-héros bovien qui pour une fois agit mais se fixe un objectif trop ambitieux car tentant de vaincre le monstre occupant périt dans le labyrinthe de la France occupée. De plus, le labyrinthe en tant que structure formelle devient un élément récurrent du roman.
