Hot Jupiter and Ultra-cold Saturn Formation in Dense Star Clusters
Authors: Wang Yi-Han , Leigh Nathan W. C. , Perna Rosalba , Shara Michael M. 
Published: December 2020

Abstract
The discovery of high incidence of hot Jupiters in dense clusters challenges the field-based hot Jupiter formation theory. In dense clusters, interactions between planetary systems and flyby stars are relatively common. This has a significant impact on planetary systems, dominating hot Jupiter formation. In this paper, we perform high precision, few-body simulations of stellar flybys and subsequent planet migration in clusters. A large parameter space exploration demonstrates that close flybys that change the architecture of the planetary system can activate high eccentricity migration mechanisms: LK and planet–planet scattering, leading to high hot Jupiter formation rate in dense clusters. Our simulations predict that many of the hot Jupiters are accompanied by “ultra-cold Saturns,” expelled to apastra of thousands of astronomical units. This increase is particularly remarkable for planetary systems originally hosting two giant planets with semimajor axis ratios of ∼4 and the flyby star approaching nearly perpendicular to the planetary orbital plane. The estimated lower limit to the hot Jupiter formation rate of a virialized cluster is

Gyr−1 per star, where σ is the cluster velocity dispersion, a
p is the size of the planetary system, and M
c is the mass of the cluster. Our simulations yield a hot Jupiter abundance that is ∼50 times smaller than that observed in the old open cluster M67. We expect that interactions involving binary stars, as well as a third or more giant planets, will close the discrepancy.

Abstract
Using 10 sight lines observed with the Hubble Space Telescope/Cosmic Origins Spectrograph, we study the circumgalactic medium (CGM) and outflows of IC 1613, which is a low-mass (M
* ∼ 108
M
⊙), dwarf irregular galaxy on the outskirts of the Local Group. Among the sight lines, four are pointed toward UV-bright stars in IC 1613, and the other six sight lines are background QSOs at impact parameters from 6 kpc (<0.1R
200) to 61 kpc (0.6R
200). We detect a number of Si ii, Si iii, Si iv, C ii, and C iv absorbers, most of which have velocities less than the escape velocity of IC 1613 and thus are gravitationally bound. The line strengths of these ion absorbers are consistent with the CGM absorbers detected in dwarf galaxies at low redshifts. Assuming that Si ii, Si iii, and Si iv comprise nearly 100% of the total silicon, we find 3% (∼8 × 103
M
⊙), 2% (∼7 × 103
M
⊙), and 32%–42% [∼(1.0–1.3) × 105
M
⊙] of the silicon mass in the stars, interstellar medium, and within 0.6R
200 of the CGM of IC 1613. We also estimate the metal outflow rate to be

and the instantaneous metal mass loading factor to be η
Z ≥ 0.004, which are in broad agreement with available observation and simulation values. This work is the first time a dwarf galaxy of such low mass is probed by a number of both QSO and stellar sight lines, and it shows that the CGM of low-mass, gas-rich galaxies can be a large reservoir enriched with metals from past and ongoing outflows.
SCORCH. III. Analytical Models of Reionization with Varying Clumping Factors
Authors: Chen Nianyi , Doussot Aristide , Trac Hy , Cen Renyue 
Published: December 2020

Abstract
In the Simulations and Constructions of the Reionization of Cosmic Hydrogen (SCORCH) project, we compare analytical models of the hydrogen ionization fraction with radiation–hydrodynamic simulations. We derive analytical models of the mass-weighted hydrogen ionization fraction from the local ionization balance equations as a more accurate alternative to the widely adopted model based on the volume filling factor. In particular, our model has a recombination term quadratic in the ionization fraction, which is consistent with the two-body interaction nature of recombination. Then, we use the radiation–hydrodynamic simulations to study the clumping factors needed to solve the analytical equations and provide accurate fitting functions. We find that the ionized hydrogen clumping factors from our radiative transfer simulations are significantly different than those from other simulations that use a uniform photoionization background. In addition to redshift dependence, we also see the dependence of the ionized hydrogen clumping factor on ionization fraction, and we incorporate this into our fits. We calculate the reionization histories using our analytical models and clumping factors and compare with widely adopted models, and all of our models achieve <7% difference from simulation results, while the other models have >20% deviations. The Thomson optical depths from reionization calculated from our analytical models result in <5% deviation from simulations, while the previous analytical models have a >20% difference and could result in biased conclusions of the intergalactic medium reionization.
Vertov ou l’apothéose de l’appareil
Authors: Krajewski Pascal 
Published: December 2020

L’article étudie comment le concept d’Appareil proposé par Jean-Louis Déotte pourrait s’éclairer du travail de Dziga Vertov, qui opta pour une approche réflexive, aussi pratique que théorique, de l’art cinématographique. En effet, les films de Vertov sont les premiers à avoir exhibé le cinéma en son dispositif, exploré son esthétique vibrionnante, réfléchi sur son impact politique et tenté de montrer la vérité de l’homme contemporain. Vertov faisait du cinéma documentaire comme un militant, un militant du cinéma-vérité et de la fabrique des faits fondés sur la connaissance, l’expérimentation et l’apparition de son médium de prédilection, à savoir les images cinématographiques d’archive.
Le nom, la carte et le monde
Authors: Jiménez Román Domínguez 
Published: December 2020

Bien que l’œuvre de Jean-Louis Déotte dessine une ligne à peu près chronologique des appareils, des normes d’écriture et des cosmétiques tout au long du devenir de la culture et de la technique, on sait que ses analyses les plus précises se centrent sur lesdits appareils modernes, tantôt constituants, tantôt issus de l’écriture projective : perspective, camera obscura, photographie, musée, passages urbains, psychanalyse, cinéma. Le dessein du texte qui suit est de suggérer, du moins comme hypothèse, que l’écriture projective aurait érigé un autre appareil encore : la cartographie moderne. Pour ce faire, il faut évidemment montrer comment la cartographie ne se réduit pas à un dispositif de pouvoir : elle serait aussi un des modes de la rêverie collective qui, dans la modernité, se développe comme un désir de territoire et, plus précisément, comme un désir de monde qui passe par sa représentation projective. Cela implique inévitablement une discussion avec Heidegger, mais aussi une recherche sur l’un des thèmes récurrents chez Déotte : la question du nom propre et de la nomination. C’est parce que la cartographie moderne établit un lien entre les noms propres, la ligne graphique et la surface de représentation, qu’elle arrive à constituer une cosmétique qui évoque l’unité magique primitive de Simondon.
Inscrire les fantômes dans les villes
Authors: Vera Adolfo 
Published: December 2020

Dans cet article, nous nous proposons de développer une théorie philosophique de la trace qui pourra, à partir de la lecture que fait Jacques Derrida de la psychanalyse, élaborer une esthétique « spectrale » qui surgit de l’occupation des villes ayant dû faire face à des violences extrêmes (notamment la disparition politique) par des images des corps dans quelques expériences artistiques, comme celles du Siluetazo (1983) argentin. Pour ce faire, il nous faudra essayer d’établir les rapports entre trace, archive, inscription, images techniques et innervations des corps. Tout ceci nous conduira à montrer comment l’art, quand il dépasse ses limites institutionnelles et acquiert le statut d’expérience collective, est à même d’accueillir les fantômes qui hantent nos sociétés et nos villes en exigeant justice.
Archives et vestiges de la grotte du château de Noisy
Authors: Bentz Bruno 
Published: December 2020

La grotte du château de Noisy a été bâtie en 1582 pour Albert de Gondi. Elle se trouvait au rez-de-chaussée d’un grand pavillon au cœur d’un vaste jardin en terrasses, avant d’être démolie en 1732. Plusieurs témoignages en ont gardé le souvenir, notamment des gravures de Jean Marot, une longue description et une série de plans datant de la fin du xviie siècle, à l’époque où la propriété avait été acquise par Louis XIV. Intégré au domaine royal dans la forêt de Marly, le site a été préservé. Des fouilles archéologiques ont pu y être entreprises en 2017 et 2019. Elles ont mis au jour les fondations de la grotte et une partie des décors, encore en place ou mêlés à la couche de remblais issus de la démolition. Ces décors associent, dans des supports en plâtre, une grande variété de rocailles et de coquilles, ainsi que des éléments dorés et sculptés. L’analyse des archives et des vestiges met en évidence la richesse et la complémentarité des sources pour retracer l’histoire et les conditions de la fabrication de ce qui fut probablement un chef-d’œuvre d’architecture et de décoration de la Renaissance.

ABSTRACTThe global malaria burden has decreased substantially, but gains have been uneven both within and between countries. In Zambia, the malaria burden remains high in northern and eastern regions of the country. To effectively reduce malaria transmission in these areas, evidence-based intervention strategies are needed. Zambia’s National Malaria Control Centre conducted targeted indoor residual spraying (IRS) in 40 high-burden districts from 2014 to 2016 using the novel organophosphate insecticide pirimiphos-methyl. The Southern and Central Africa International Centers of Excellence for Malaria Research conducted an evaluation of the impact of the IRS campaign on household vector abundance in Nchelenge District, Luapula Province. From April 2012 to July 2017, field teams conducted indoor overnight vector collections from 25 to 30 households per month using Centers for Disease Control light traps. Changes in indoor anopheline counts before versus after IRS were assessed by species using negative binomial regression models with robust standard errors, controlling for geographic and climatological covariates. Counts of Anopheles funestus declined by approximately 50% in the study area and within areas targeted for IRS, and counts of Anopheles gambiae declined by approximately 40%. Within targeted areas, An. funestus counts declined more in sprayed households than in unsprayed households; however, this relationship was not observed for An. gambiae. The moderate decrease in indoor vector abundance indicates that IRS with pirimiphos-methyl is an effective vector control measure, but a more comprehensive package of interventions is needed with sufficient coverage to effectively reduce the malaria burden in this setting.

ABSTRACTSera from white-tailed deer (WTD, Odocoileus virginianus) hunter-harvested throughout New York State (NYS), 2007–2015, were tested by plaque reduction neutralization for antibodies against nine mosquito-borne viruses from the families Peribunyaviridae, Flaviviridae, and Togaviridae. Overall, 76.1% (373/490) of sampled WTD were seropositive against at least one virus, and 38.8% were exposed to multiple viruses. The seropositivity rate in adult WTD (78.0%) was significantly greater (P < 0.0001) than that in fawns (47.7%). Neutralizing antibodies against California serogroup viruses were most common in WTD sampled across all regions (67.1%), followed by the Bunyamwera serogroup (BUN) (37.6%). Jamestown Canyon and Cache Valley orthobunyaviruses were responsible for most California and BUN infections, respectively. Seroprevalence rates to West Nile virus were higher in samples originating from Long Island (LI) (19.0%) than in those originating from the central (7.3%), western (5.0%), and Hudson Valley (4.4%) regions of NYS. Antibodies to Eastern equine encephalitis virus were seen primarily in WTD from central NYS (5.1%), where annual enzootic activity occurs, but low rates were documented in western NYS (1.4%) and LI (1.7%). Low rates of Potosi and LaCrosse orthobunyavirus, and Highlands J virus antibodies were detected over the course of this investigation. St. Louis encephalitis virus (or a closely related virus) antibodies were detected in samples collected from central and western NYS, suggesting local virus transmission despite a lack of evidence from routine mosquito surveillance. Serologic results demonstrate the value of WTD in NYS as an indicator of arbovirus distribution and recent transmission on a relatively fine spatial scale.
ensino e aprendizagem de línguas em contextos plurilingues: políticas e estratégias didáctico-metodológicas para o ensino bilingue em Moçambique
Authors: Gundane Lucério , Chicavele Benedito 
Published: December 2020

Resumo: À luz de Vygotsky (1962), Hymes (1970, 1972) e Heugh (2011), o estudo analisa e descreve os fenómenos linguísticos e extralinguísticos envolvidos no PEA de línguas em contextos plurilingues. São apresentadas práticas e políticas sobre línguas, estratégias e perspectivas didáctico-metodológicas a serem observadas durante o ensino das línguas bantu como L1 e do Português como L2 em Moçambique. Trata-se de uma pesquisa exploratória que, à luz da perspectiva analítica, se cingiu tanto na pesquisa bibliográfica, como na abordagem interdisciplinar, porque foi desenvolvida com base num vasto referencial teórico que incide sobre a prática educativa escolar, ensino e aprendizagem de línguas. Os resultados mostram que no que refere ao ensino bilingue, Moçambique deve adoptar o modelo de manutenção, visto que este promove o património sociocultural e linguístico do aluno. Este modelo de ensino de línguas deve estar voltado ao desenvolvimento de competências do aluno e as actividades devem ser variadas em função dos objectivos e conteúdos pedagógicos específicos. Conclui-se ainda que o ensino de línguas em contextos plurilingues requer algum equilíbrio, num processo em que os objectivos do ensino não são definidos considerando-se apenas os conteúdos de aprendizagem, mas enfatizar-se um conjunto de habilidades que o aluno tem de desenvolver.

Background: Malaria is the most important parasitic infections in the world, including in Indonesia. Kabupaten North Kayong is one of malaria endemic areas in West Kalimantan. Tanjung Satai village is one of the village that has the highest Annual Parasite Incidence (API) with number 15,89 per 1 000 at Kabupaten North Kayong. The incidence of malaria is influenced by the level of knowledge, individual behavior, the physical condition of the house and the house environment Objectives: To find out the comparison between the level of knowledge, individual behavior, the physical condition of the house and the house environment with the incidence of malaria in Tanjung Satai village and Kemboja village, Kabupaten North Kayong. Methods: This research was case control design. Cases were residents who had positive malaria in 2011 and controls were residents who have never had malaria. Bivariate analysis used Chi-Square test. Results: The number of samples in this research were 110 respondents (55 of case respondents and 55 of control respondents). The independent variables that influenced the incidence of malaria are the level of knowledge (p=0,007; OR=2,88), using the mosquito net (p=0,039; OR=3,09), the existence of bushes (p=0,001; OR=0,27) and the existence of stagnant water (p=0,016; OR=0,37). The independent variables that did not influence the incidence of malaria are using mosquito repellent, installing wire net, and the density of house wall. Conclusion: The lower level of knowledge, not using the mosquito net, the existence of bushes and the existence of stagnant water have risk 2,88; 3,09; 0,27; 0,37 times to get malaria.
