Monitoring the Superorbital Period Variation and Spin Period Evolution of SMC X-1
Authors: Hu Chin-Ping , Mihara Tatehiro , Sugizaki Mutsumi , Ueda Yoshihiro , Enoto Teruaki 
Published: November 2019

Abstract
The X-ray pulsar SMC X-1 shows a superorbital modulation with an unstable cycle length in the X-ray band. We present its timing behaviors, including the spin, orbital, and superorbital modulations, beyond the end of the Rossi X-ray Timing Explorer mission. The time-frequency maps derived by the wavelet Z-transform and the Hilbert–Huang transform suggest that a new superorbital period excursion event occurred in ∼MJD 57,100 (2015 March). This indicates that the excursion is recurrent and probably (quasi)periodic. The hardness ratio obtained with the Monitor of All-sky X-ray Image (MAXI) suggests increased absorption during the transition from the high to the low state in the superorbital cycle. Compared to the regular epochs, the superorbital profile during the excursion epochs has a shallower and narrower valley, likely caused by a flatter warp. By tracking the spin period evolution with the MAXI Gas Slit Camera in 2–20 keV, we derive an averaged spin-up rate of

s−2 during the period between MJD 55,141 (2009 November) and 58,526 (2019 February). We obtain no positive correlation between the spin frequency residual and the superorbital frequency, but a torque change accompanying the superorbital period excursion is possible. We suggest that the accretion torque on the neutron star could be changed by various mechanisms, including the change of mass accretion rate and the warp angle. We update the value of the orbital decay as

Modeling Mg ii during Solar Flares. II. Nonequilibrium Effects
Authors: Kerr Graham S. , Carlsson Mats , Allred Joel C. 
Published: November 2019

Abstract
To extract the information that the Mg ii NUV spectra (observed by the Interface Region Imaging Spectrograph) carry about the chromosphere during solar flares, and to validate models of energy transport via model–data comparison, forward modeling is required. The assumption of statistical equilibrium (SE) is typically used to obtain the atomic level populations from snapshots of flare atmospheres, due to computational necessity. However, it is possible that relying on SE could lead to spurious results. We compare solving the atomic level populations via SE versus a nonequilibrium (NEQ) time-dependent approach. This was achieved using flare simulations from RADYN alongside the minority species version MS_RADYN from which the time-dependent Mg ii atomic level populations and radiation transfer were computed in complete frequency redistribution. The impacts on the emergent profiles, lightcurves, line ratios, and formation heights are discussed. In summary we note that NEQ effects during flares are typically important only in the initial stages and for a short period following the cessation of the energy injection. An analysis of the timescales of ionization equilibrium reveals that for most of the duration of the flare, when the temperatures and densities are sufficiently enhanced, the relaxation timescales are short (τ
relax < 0.1 s), so that the equilibrium solution is an adequate approximation. These effects vary with the size of the flare, however. In weaker flares, effects can be more pronounced. We recommend that NEQ effects be considered when possible but that SE is sufficient at most stages of the flare.
Can the Uranian Satellites Form from a Debris Disk Generated by a Giant Impact?
Authors: Ishizawa Yuya , Sasaki Takanori , Hosono Natsuki 
Published: November 2019

Abstract
Hydrodynamic simulations of a giant impact to proto-Uranus indicated that such an impact could tilt its rotational axis and produce a circumplanetary debris disk beyond the corotation radius of Uranus. However, whether Uranian satellites can actually be formed from such a wide disk remains unclear. Herein, we modeled a wide debris disk of solids with several initial conditions inferred from the hydrodynamic simulations and performed N-body simulations to investigate in situ satellite formation from the debris disk. We also took account of orbital evolutions of satellites due to the planetary tides after the growth of satellites. We found that, in any case, the orbital distribution of the five major satellites could not be reproduced from the disk as long as the power index of its surface density is similar to that of the disk generated just after the giant impact. Satellites in the middle region obtained much larger masses than Ariel or Umbriel, while the outermost satellites did not grow to the mass of Oberon. Our results indicate that we should consider the thermal and viscous evolution of the evaporated disk after the giant impact to form the five major satellites through the in situ formation scenario. On the other hand, the small inner satellites would be formed from the rings produced by the disrupted satellites that migrated from around the corotation radius of Uranus due to the planetary tides.
Progenitors of Type IIb Supernovae. I. Evolutionary Pathways and Rates
Authors: Sravan Niharika , Marchant Pablo , Kalogera Vassiliki 
Published: November 2019

Abstract
Type IIb supernovae (SNe) are important candidates to understand mechanisms that drive the stripping of stripped-envelope (SE) supernova (SN) progenitors. While binary interactions and their high incidence are generally cited to favor them as SN IIb progenitors, this idea has not been tested using models covering a broad parameter space. In this paper, we use non-rotating single- and binary-star models at solar and low metallicities spanning a wide parameter space in primary mass, mass ratio, orbital period, and mass transfer efficiencies. We find that our single- and binary-star models contribute to roughly equal, however small, numbers of SNe IIb at solar metallicity. Binaries only dominate as progenitors at low metallicity. We also find that our models can account for less than half of the observationally inferred rate for SNe IIb at solar metallicity, with computed rates ≲4% of core-collapse (CC) SNe. On the other hand, our models can account for the rates currently indicated by observations at low metallicity, with computed rates as high as 15% of CC SNe. However, this requires low mass transfer efficiencies (≲0.1) to prevent most progenitors from entering contact. We suggest that the stellar wind mass-loss rates at solar metallicity used in our models are too high. Lower mass-loss rates would widen the parameter space for binary SNe IIb at solar metallicity by allowing stars that initiate mass transfer earlier in their evolution to reach CC without getting fully stripped.

Authors: Pham Anh , Pham Cuong , Doan Lan , Ziegler Thomas , Nguyen Truong 
Published: November 2019

The family Megophryidae is one of the most poorly known groups of amphibians in Son La Province, Vietnam. In the herpetofaunal list of Vietnam in 2009 only two species of megophryids were recorded from this province and recent studies have documented five additional species of Megophryidae from Son La Province.
Based on recent field work in northern Vietnam, we report six new provincial records of the family Megophryidae from Son La Province, namely Leptobrachium ailaonicum, Leptobrachella sungi, Megophrys feae, M. jingdongensis, M. microstoma and M. parva. In addition, morphological data were provided for each species, based on newly collected specimens. Our findings bring the species number of the family Megophryidae to 13 in Son La Province.
« J’ai peur de ne pas pouvoir m’arrêter ». La crainte du pulsionnel chez la jeune fille anorexique
Authors: Belamich Garance 
Published: November 2019

La poussée pulsionnelle à l’adolescence, vécue comme un véritable « corps étranger interne » chez certains, peut venir menacer leur narcissisme en pleine construction, au point parfois de venir réactiver des vécus agonistiques innommables. « J’ai peur de ne plus pouvoir m’arrêter » ; telle est la terreur d’Agathe dont les symptômes (anorexie, scarifications) viennent se loger dans le corps, corps à la fois lieu du conflit et outil pour tenter de le résoudre. Quelle fonction peut parfois avoir la pulsion de destruction, notamment lorsqu’elle est retournée contre soi ? Qu’y a-t-il derrière cet acharnement à « faire le vide » chez l’anorexique ? Telles sont les questions auxquelles l’auteur tente de répondre à travers le cas d’une jeune fille suivie en hôpital de jour.
La prison, une institution de (non-) soin et l’art-thérapie
Authors: Katz-Mazilu Irina 
Published: November 2019

L’autrice explore et argumente la vision holistique et humaniste en art-thérapie. Une illustration est donnée avec un exemple issu du milieu carcéral. Bien que la raison d’être de cette institution ne soit pas le soin, la quasi-totalité des personnes y vivant en a besoin, détenu(e)s comme détenant(e)s. L’institution de non-soins qu’est la prison suscite la peur. Par quelles stratégies thérapeutiques peut-on espérer inverser la spirale descendante de l’angoisse, de la peur de l’effondrement et de la mort ? L’art-thérapie, par la créativité et le partage, offre un espace-temps de décompression, de réparation et de redynamisation.
De la collection
Authors: Josef Anne 
Published: November 2019

Cet article a l’ambition de proposer une analyse sémiotique de la pratique de la collection. En distinguant d’abord la pratique de la collection d’une simple pratique accumulative en déterminant que le geste de collection opère par réduction de l’ensemble des objets à acquérir alors que le geste d’accumulation opère par extension de l’ensemble des objets acquis, l’analyse conduite met au jour son mode opératoire. L’étude de la nature du collectionnable permet de conclure que tout ce qui est culturalisé, y compris l’être humain, peut faire l’objet d’une collection. L’autrice étudie ensuite les opérations d’acquisition qui sont de deux types : les transactions opèrent par compensation alors que les opérations de saisie n’engagent aucune compensation. Une analyse de la trophy room conclut cet article.

Abstract. A new fossil species of the silvanid flat bark beetle genus
Cathartosilvanus Grouvelle is described and illustrated from Baltic amber. Cathartosilvanus siteiterralevis sp. nov. differs
from recent and fossil congeners in the distinct, sharp denticle found along
its posterior pronotal angle. The phenomenon of specific body parts becoming
disconnected, and the compression of specimens is briefly discussed and
interpreted in the context of amber taphonomy. The specimen under study
appears to be an uncommon case of a weakly sclerotized beetle imago becoming
entrapped in resin shortly after moulting.

Laughably Disingenuous, Brazenly Bogus, Extreme Green “Lawfare”: The Rhetorical Framing of Environmentalist Actors in Coal Age Magazine
Authors: Cruger Katie , Martin Lou 
Published: November 2019

Abstract
In this project, we’ve combined methods and resources from history, communication, and rhetorical criticism in order to unpack the subtle and not-so-subtle ways in which the coal industry chips away at the credibility of reformers. The coal industry has played a central role in shaping the economic, political, and social systems of Appalachia as well as public discourse and shared values in the region. This study analyzes the framing of the terms “environmentalist” and “activist” in Coal Age magazine, a widely read industry publication, from 2011 through 2016. Industry actors are commonly depicted as good neighbors, rational conservationists, and (almost always) men of action, while “environmentalists” are their meddling, litigious, irrational, often malicious, self-serving foils. Print propaganda like this has had real-world consequences for those who oppose the industry’s environmentally destructive practices.
Climbing out of Coal Country: The Economic Impact of Rock Climbing in West Virginia’s New River Gorge
Authors: Maples James , Bradley Michael , Giles Sadie , Leebrick Rhiannon , Clark Brian 
Published: November 2019

Abstract
This study examines the economic impact of rock climbing in West Virginia’s New River Gorge. Central Appalachia’s current economy is partly the result of uneven development through resource extraction wherein value is created by permanently removing resources such as coal. In contrast, outdoor recreation economies find economic value in leaving natural spaces, such as mountains, in place. Outdoor recreation, which includes rock climbing, mountain biking, hiking, and other sports dependent on natural features, now represents an important part of the nation’s economy. This study finds that persons living outside of Fayette, Nicholas, and Raleigh Counties visiting West Virginia’s New River Gorge to climb spent an estimated $12.1 million in 2018. Non-local climber expenditures supported an estimated 168 jobs and $6.3 million in wages in the study area. Over 70 percent of climbers in the sample had a bachelor’s degree or higher, with one in five possessing graduate degrees. Altogether, 48 percent of climbers in the sample made $50,000 or higher in annual personal income, with one in ten reporting six-figure annual personal incomes. Overall, this study gives cause for further examination of economic growth through outdoor recreation and its economic contributions.

A loucura e as pedras na literatura de Drummond
Authors: De oliveira Cristina maria 
Published: November 2019

A sociedade, em várias épocas, segregou a loucura nos espaços sociais como na rua, no internamento, nas prisões ou na própria casa do sujeito. Para Foucault (1978) a loucura foi e continua sendo objeto de um olhar que torna invisível as diferenças, com intolerância e medo. São no espaço e no tempo da cidade que os sujeitos se encontram e desencontram, desenvolvendo seus vínculos ou os desatando com seus desejos, afetos, conflitos. A loucura pode ser representada na literatura que absorve o imaginário do escritor para enunciar cenas que refletem o cotidiano, abordam a realidade e constroem outra realidade repleta do imaginário e que trazem para o leitor as infinitas possibilidades de resolver as tensões do texto. Esse artigo apresenta como objetivo analisar o conto, de Carlos Drummond de Andrade, “A Doida”, que está inserido no livro Contos de Aprendiz (1951), trazendo o olhar infantil para a percepção da loucura que se desloca da agressão à louca, quando os meninos atiram pedras contra ela, para a solidariedade e sensibilidade humanas, representadas por um dos meninos, quando ele descobre que a louca é uma velha, uma mulher, que merece ser cuidada no seu leito de morte.
Os rastros psicanalíticos em Drummond: uma análise do poema “A mesa”
Authors: Andrade Juliana Pereira 
Published: November 2019

O poeta Carlos Drummond de Andrade, nos inúmeros poemas que escreveu, abordou diversas temáticas diferentes. Uma dessas temáticas é a da "família" que tem bastante relevância dentro de sua obra devido a um teor autobiográfico. Em uma das antologias do poeta, que foi publicada em 1962, há uma seção dedicada a esse tema familiar, contando com um total de dez poemas. A relevância de se ter um elemento que certa forma é biográfico do autor, principalmente no que tange à questão familiar, está centrado na possibilidade de fazer uma análise psicanalítica, para além daquilo que está evidente do texto. Baseando-se nas teorias psicanalistas de Lacan e Freud, a partir da perspectiva de Helio Pellegrino, esse artigo pretende explorar um dos poemas dessa antologia, intitulado “A mesa”. O objetivo é analisar as relações entre pai, mãe e filho presentes no mesmo a partir dos conceitos psicanalíticos.
