Reflecting the Man: Gendering Race in Paul Haggis’s Crash
Authors: Elliott Mandy 
Published: July 2018

Résumé : Le film Crash (Collision) de Paul Haggis (2004) emploie la fluidité des rôles de genre pour illustrer des cas d’iniquité raciale et les réactions qu’ils suscitent. L’auteure démontre de quelles façons le film joue avec l’idée que se fait Frantz Fanon du regard raciste comme forme de castration métaphorique — le remplacement systématique de la puissance sexuelle masculine par une objectification et une soumission forcées. Dans l’esprit des travaux de Fanon, Daniel Kim déclare que le regard homosocial du mâle blanc « force les hommes de couleur à féminiser leur position », affirmant la supériorité raciale à travers le langage de la domination sexuelle. Dans Crash, Christine (Thandie Newton) et Cameron (Terrence Howard) Thayer sont tous les deux privés de leur identité sexuelle à titre de gens de couleur. Bien que cette castration métaphorique ne soit pas nécessairement permanente, elle met en relief le lien inéluctable entre race et genre et les pairages qui tendent à dicter la domination et la soumission.
Modeling of the Hydrogen Lyman Lines in Solar Flares
Authors: Brown Stephen A. , Fletcher Lyndsay , Kerr Graham S. , Labrosse Nicolas , Kowalski Adam F. , Rodríguez Jaime De La Cruz 
Published: July 2018

Abstract
The hydrogen Lyman lines (91.2 nm < λ < 121.6 nm) are significant contributors to the radiative losses of the solar chromosphere, and they are enhanced during flares. We have shown previously that the Lyman lines observed by the Extreme Ultraviolet Variability instrument onboard the Solar Dynamics Observatory exhibit Doppler motions equivalent to speeds on the order of 30 km s−1. However, contrary to expectations, both redshifts and blueshifts were present and no dominant flow direction was observed. To understand the formation of the Lyman lines, particularly their Doppler motions, we have used the radiative hydrodynamic code, RADYN, along with the radiative transfer code, RH, to simulate the evolution of the flaring chromosphere and the response of the Lyman lines during solar flares. We find that upflows in the simulated atmospheres lead to blueshifts in the line cores, which exhibit central reversals. We then model the effects of the instrument on the profiles, using the Extreme Ultraviolet Variability Experiment (EVE) instrument's properties. What may be interpreted as downflows (redshifted emission) in the lines, after they have been convolved with the instrumental line profile, may not necessarily correspond to actual downflows. Dynamic features in the atmosphere can introduce complex features in the line profiles that will not be detected by instruments with the spectral resolution of EVE, but which leave more of a signature at the resolution of the Spectral Investigation of the Coronal Environment instrument onboard the Solar Orbiter.
Faraday Conversion in Turbulent Blazar Jets
Authors: MacDonald Nicholas R. , Marscher Alan P. 
Published: July 2018

Abstract
Low (≲1%) levels of circular polarization (CP) detected at radio frequencies in the relativistic jets of some blazars can provide insight into the underlying nature of the jet plasma. CP can be produced through linear birefringence, in which initially linearly polarized emission produced in one region of the jet is altered by Faraday rotation as it propagates through other regions of the jet with varying magnetic field orientation. Marscher has begun a study of jets with such magnetic geometries using the turbulent extreme multi-zone (TEMZ) model, in which turbulent plasma crossing a standing shock in the jet is represented by a collection of thousands of individual plasma cells, each with distinct magnetic field orientations. Here we develop a radiative transfer scheme that allows the numerical TEMZ code to produce simulated images of the time-dependent linearly and circularly polarized intensity at different radio frequencies. In this initial study, we produce synthetic polarized emission maps that highlight the linear and circular polarization expected within the model.
Spectroscopic Determination of Capella’s Photospheric Abundances: Possible Influence of Stellar Activity
Authors: Takeda Yoichi , Hashimoto Osamu , Honda Satoshi 
Published: July 2018

Abstract
Capella is a spectroscopic binary consisting of two G-type giants, where the primary (G8 iii) is a normal red clump giant while the secondary (G0 iii) is a chromospherically active fast rotator showing considerable overabundance of Li as Li-enhanced giants. Recently, Takeda & Tajitsu reported that abundance ratios of specific light elements (e.g., [C/Fe] or [O/Fe]) in Li-rich giants of high activity tend to be anomalously high, which they suspected to be nothing but superficial caused by unusual atmospheric structure due to high activity. Toward verifying this hypothesis, we determined the elemental abundances of the primary and the secondary of Capella based on the disentangled spectrum of each component, in order to see whether any apparent disagreement exists between the two, which should have been formed with the same chemical composition. We found that the primary is slightly supersolar (by ∼+0.1 dex), while the secondary is subsolar (by several tenths of dex) for heavier elements such as Fe, resulting in a marked discrepancy between the primary and secondary, though such a trend is not seen for light elements (e.g., C or O). These observational facts suggest that anomalously large [X/Fe] ratios found in Li-rich giants were mainly due to an apparent decrease of Fe abundance, which we speculate is caused by the overionization effect due to chromospheric UV radiation. We thus conclude that conventional model-atmosphere analysis would fail to correctly determine the abundances of fast-rotating giants of high activity, for which proper treatment of the chromospheric effect is required for deriving true photospheric abundances.

Abstract
We investigate the impact of the far-UV (FUV) heating rate on the stability of the three-phase interstellar medium using three-dimensional simulations of a

Even absent a variable star formation rate regulating the FUV heating rate, the gas physics keeps the pressure in the two-phase regime: because radiative heating and cooling processes happen on shorter timescales than sound wave propagation, turbulent compressions tend to keep the interstellar medium within the CNM–WNM pressure regime over a wide range of heating rates. The thermal pressure is set primarily by the heating rate with little influence from the hydrostatics. The vertical velocity dispersion adjusts as needed to provide hydrostatic support given the thermal pressure: when the turbulent pressure

Abstract
Chronic obstructive pulmonary disease is a chronic inflammatory disorder with an increased incidence of lung cancer. The emphysema component of chronic obstructive pulmonary disease confers the greatest proportion to lung cancer risk. Although tumors create inflammatory conditions to escape immunity, the immunological responses that control growth of nascent cancer cells in pre-established inflammatory microenvironments are unknown. In this study, we addressed this issue by implanting OVA-expressing cancer cells in the lungs of mice with cigarette smoke–induced emphysema. Emphysema augmented the growth of cancer cells, an effect that was dependent on T cytotoxic cells. OVA-specific OTI T cells showed early signs of exhaustion upon transfer in emphysema tumor hosts that was largely irreversible because sorting, expansion, and adoptive transfer failed to restore their antitumor activity. Increased numbers of PD-L1– and IDO-positive CD11c+ myeloid dendritic cells (DCs) infiltrated emphysema tumors, whereas sorted emphysema tumor DCs poorly stimulated OTI T cells. Upon adoptive transfer in immunocompetent hosts, T cells primed by emphysema tumor DCs were unable to halt tumor growth. DCs exposed to the emphysema tumor microenvironment downregulated MHC class II and costimulatory molecules, whereas they upregulated PD-L1/IDO via oxidative stress–dependent mechanisms. T cell activation increased upon PD-L1 blockade in emphysema DC–T cell cocultures and in emphysema tumor hosts in vivo. Analysis of the transcriptome of primary human lung tumors showed a strong association between computed tomography–based emphysema scoring and downregulation of immunogenic processes. Thus, suppression of adaptive immunity against lung cancer cells links a chronic inflammatory disorder, emphysema, to cancer, with clinical implications for emphysema patients to be considered optimal candidates for cancer immunotherapies.
