3D Radiation Hydrodynamics of a Dynamical Torus
Authors: Williamson David , Hönig Sebastian , Venanzi Marta 
Published: May 2019

Abstract
We have developed a new dynamical model of the torus region in active galactic nuclei (AGNs), using a three-dimensional radiation hydrodynamics algorithm. These new simulations have the specific aim to explore the role of radiatively driven outflows, which is hotly debated in current literature as a possible explanation for the observed IR emission from the polar regions of AGNs. In this first paper, we only consider radiative effects induced by the primary radiation from the AGN. The simulations generate a disk and outflow structure that qualitatively agrees with observations, although the outflow is radial rather than polar, likely due to the lack of radiation pressure from hot dust. We find cutoffs between the wind and disk at gas temperatures of 1000 K and dust temperatures of 100 K, producing kinematic signatures that can be used for interpretation of high-resolution IR observations. We also produce line emission maps to aid in the interpretation of recent ALMA observations and future James Webb Space Telescope observations. We investigate a number of simulation parameters and find that the anisotropy of the radiation field is equally important to the Eddington factor, despite the anisotropy often being assumed to have a single, sometimes arbitrary form in many previous works. We also find that supernovae can have a small but significant impact, but only at extremely high star formation rates.

Abstract
One clear observational prediction of the single-degenerate progenitor scenario as the origin of type Ia supernovae (SNe) is the presence of relatively narrow (≈1000 km s−1) Hα emission at nebular phases, although this feature is rarely seen. We present a compilation of nebular phase Hα limits for SN Ia in the literature and demonstrate that this heterogenous sample has been biased toward SN Ia with relatively high luminosities and slow decline rates, as parameterized by Δm
15(B), the difference in B-band magnitude between maximum light and 15 days afterward. Motivated by the need to explore the full parameter space of SN Ia and their subtypes, we present two new and six previously published nebular spectra of SN Ia with Δm
15(B) > 1.3 mag (including members of the transitional and SN1991bg-like subclasses) and measure nondetection limits of L
Hα
< 0.85–9.9 × 1036 erg s−1, which we confirmed by implanting simulated Hα emission into our data. Based on the latest models of swept-up material stripped from a nondegenerate companion star, these L
Hα
values correspond to hydrogen mass limits of M
H ≲ 1–3 × 10−4
M
⊙, which are roughly three orders of magnitude below that expected for the systems modeled, although we note that no simulations of Hα nebular emission in such weak explosions have yet been performed. Despite the recent detection of strong Hα in ASASSN-18tb (SN 2018fhw; Δm
15(B) = 2.0 mag), we see no evidence that fast-declining systems are more likely to have late time Hα emission, although a larger sample is needed to confirm this result.
Libération sexuelle ou « pression à soulager ces messieurs » ? Points de vue de femmes dans les années 68 en France
Authors: Ruault Lucile 
Published: May 2019

Le rapport très ambivalent qu’entretiennent des femmes à certains préceptes des années 1968 en France invite à examiner comment une politique sexuelle et affective dite révolutionnaire a reconduit des normes androcentrées. Il s’agit ainsi de contribuer à l’étude des incidences de ce moment de crise sur les rapports sociaux de sexe, en explorant « par le bas » les implications ambiguës du bouleversement de l’ordre sexuel, c’est-à-dire à la fois l’ouverture de possibles et la restauration d’une domination. Cet article veille à analyser ces codes sexuels à la lumière des dispositions affectives des femmes.
La gêne olfactive comme processus collectif d’attachement
Authors: Daniel François-Joseph 
Published: May 2019

L’article tente de décrire les processus perceptuels, cognitifs, attentionnels à travers lesquels le sentiment de gêne se diffuse sur un territoire de nuisances environnementales. En prenant l’exemple des nuisances olfactives d’origine industrielle, il montre que la gêne agit comme un processus réflexif d’attachement à un objet non désiré (les mauvaises odeurs). L’examen minutieux de ce processus montre que la relation d’attachement s’enracine dans une dynamique collective de transformation du régime d’attention portée à la nuisance : de l’indifférence à l’obsession. Cette dynamique socio-sensorielle aboutit à la constitution d’une véritable communauté d’affects dont le périmètre délimite le territoire de gêne.
Risk Factors for Initial and Subsequent Core or Lower Extremity Sprain or Strain Among Collegiate Football Players
Authors: McDonald Alexandra A. , Wilkerson Gary B. , McDermott Brendon P. , Bonacci Jeffrey A. 
Published: May 2019

Context
Exposure to game conditions and previous injury are known to increase the risk of injury, but little available evidence pertains to modifiable factors that may mediate dynamic control of body segments, such as core muscle endurance and neurocognitive capabilities.

Objective
To identify potentially modifiable factors associated with the occurrence of a core or lower extremity sprain or strain during participation in football.

Design
Prospective cohort study.

Setting
National Collegiate Athletic Association Division I Football Bowl Subdivision football program.

Patients or Other Participants
All team members who participated for the duration of 1 season or both of 2 consecutive seasons (n = 142).

Main Outcome Measure(s)
Predictors of injury occurrence were derived from analysis of preparticipation data that included the results of front plank hold (FPH) and neurocognitive tests. Receiver operating characteristic analysis was used to establish binary classifications of injury risk. Logistic regression analyses were conducted to build multivariable injury-prediction models for optimal discriminatory power.

Results
Exceptionally good discrimination between injured and noninjured participants was provided by models that included the results of the FPH and ImPACT neurocognitive tests. A high level of exposure to game conditions and injury during the preceding year magnified the effects of other risk factors. A model for identifying players with an elevated risk for injury occurrence during both of 2 consecutive seasons included FPH ≤120 seconds, verbal memory score ≤87, composite reaction time ≥560 milliseconds, and starter status. Having ≥2 of the 4 risk factors demonstrated 44% sensitivity and 91% specificity, with an odds ratio = 8.40.

Conclusions
Core muscle endurance and neurocognitive processes may both play important roles in generating anticipatory muscle stiffness during participation in collegiate football. These factors may be particularly important for players who sustained an injury during the previous year and those who have a high level of game exposure.

Published: May 2019

Abstract. Growing shipping activities in port areas have generated negative impacts on climate, air
quality and human health. To better evaluate the environmental impact of ship
emissions, an experimental characterization of air pollution from ships was
conducted in Shanghai Port in the summer of 2016. The ambient concentrations
of gaseous NO, NO2, SO2 and O3 in addition to
fine particulate matter concentrations (PM2.5), particle size
distributions and the chemical composition of individual particles from ship
emission were continuously monitored for 3 months. Ship emission plumes were
visible at the port site in terms of clear peaks in the gaseous species and
particulate matter concentrations. The SO2 and vanadium particle
numbers were found to correlate best with ship emissions in Shanghai Port.
Single-particle data showed that ship emission particles at the port site
mainly concentrated in a smaller size range (<0.4 µm), where
their number contributions were more important than their mass contributions
to ambient particulate matter. The composition of ship emission particles at
the port site suggested that they were mostly freshly emitted particles:
their mass spectra were dominated by peaks of sulfate, elemental carbon (EC),
and trace metals such as V, Ni, Fe and Ca, in addition to displaying very low
nitrate signals. The gaseous NOx composition in some cases of
plumes showed evidence of atmospheric transformation by ambient O3,
which subsequently resulted in O3 depletion in the area.
Quantitative estimations in this study showed that ship emissions contributed
36.4 % to SO2, 0.7 % to NO, 5.1 % to NO2,
−0.9 % to O3, 5.9 % to PM2.5 and 49.5 % to
vanadium particles in the port region if land-based emissions were included,
and 57.2 % to SO2, 71.9 % to NO, 30.4 % to
NO2, −16.6 % to O3, 27.6 % to PM2.5 and
77.0 % to vanadium particles if land-based emissions were excluded.

Published: May 2019

Abstract. The International Centre for Global Earth Models (ICGEM,
http://icgem.gfz-potsdam.de/, last access: 6 May 2019) hosted at the
GFZ German Research Centre for Geosciences (GFZ) is one of the five services
coordinated by the International Gravity Field Service (IGFS) of the
International Association of Geodesy (IAG). The goal of the ICGEM service is
to provide the scientific community with a state-of-the-art archive of static
and temporal global gravity field models of the Earth, and develop and
operate interactive calculation and visualization services of gravity field
functionals on user-defined grids or at a list of particular points via its
website. ICGEM offers the largest collection of global gravity field models,
including those from the 1960s to the 1990s, as well as the most recent ones,
which have been developed using data from dedicated satellite gravity
missions, CHAMP, GRACE, GOCE, advanced processing methodologies, and
additional data sources such as satellite altimetry and terrestrial gravity.
The global gravity field models have been collected from different
institutions at international level and after a validation process made
publicly available in a standardized format with DOI numbers assigned through
GFZ Data Services. The development and maintenance of such a unique platform
is crucial for the scientific community in geodesy, geophysics, oceanography,
and climate research. In this article, we present the development history and
future plans of ICGEM and its current products and essential services. We
present the ICGEM's data by means of Earth's static, temporal, and
topographic gravity field models as well as the gravity field models of other
celestial bodies together with examples produced by the ICGEM's calculation
and 3-D visualization services and give an insight into how the ICGEM service
can additionally contribute to the needs of research and society.
Contribution of low-frequency climatic–oceanic oscillations to streamflow variability in small, coastal rivers of the Sierra Nevada de Santa Marta (Colombia)
Authors: Restrepo Juan Camilo , Higgins Aldemar , Escobar Jaime , Ospino Silvio , Hoyos Natalia 
Published: May 2019

Abstract. This study evaluated the influence of
low-frequency oscillations, that are linked to large-scale
oceanographic–atmospheric processes, on streamflow variability in small
tropical coastal mountain rivers of the Sierra Nevada de Santa Marta,
Colombia. We used data from six rivers that had > 32 years of
complete, continuous monthly streamflow records. This investigation employed
spectral analyses to (1) explore temporal characteristics of streamflow
variability, (2) estimate the net contribution to the energy spectrum of
low-frequency oscillations to streamflow anomalies, and (3) analyze the
linkages between streamflow anomalies and large-scale, low-frequency
oceanographic–atmospheric processes. Wavelet analyses indicate that the
8–12-year component exhibited a quasi-stationary state, with a peak of
maximum power between 1985 and 2005. These oscillations were nearly in phase
in all rivers. Maximum power peaks occurred for the Palomino and Rancheria
rivers in 1985 and 1995, respectively. The wavelet spectrum highlights a
change in river variability patterns between 1995 and 2015, characterized by
a shift towards the low-frequency oscillations' domain (8–12 years). The net
contribution of these oscillations to the energy spectrum was as high as
51 %, a value much larger than previously thought for rivers in
northwestern South America. The simultaneous occurrence of hydrologic
oscillations, as well as the increase in the amplitude of the 8–12-year
band, defined periods of extremely anomalous wet seasons during 1989–1990,
1998–2002 and 2010–2011, reflecting the role of low-frequency oscillations
in modulating streamflow variability in these rivers. Cross-wavelet transform
and wavelet coherence revealed high common powers and significant coherences
in low-frequency bands (>96 months) between streamflow anomalies and
Atlantic Meridional Oscillation (AMO), Pacific Decadal Oscillation (PDO) and
the Tropical North Atlantic Index (TNA). These results show the role of
large-scale, low-frequency oceanographic–climate processes in modulating the
long-term hydrological variability of these rivers.

Abstract. Ice sheet numerical modeling is an important tool to estimate the dynamic
contribution of the Antarctic ice sheet to sea level rise over the coming
centuries. The influence of initial conditions on ice sheet model
simulations, however, is still unclear. To better understand this influence,
an initial state intercomparison exercise (initMIP) has been developed to
compare, evaluate, and improve initialization procedures and estimate their
impact on century-scale simulations. initMIP is the first set of experiments
of the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6), which is
the primary Coupled Model Intercomparison Project Phase 6 (CMIP6) activity
focusing on the Greenland and Antarctic ice sheets. Following
initMIP-Greenland, initMIP-Antarctica has been designed to explore
uncertainties associated with model initialization and spin-up and to
evaluate the impact of changes in external forcings. Starting from the state
of the Antarctic ice sheet at the end of the initialization procedure, three
forward experiments are each run for 100 years: a control run, a run with a
surface mass balance anomaly, and a run with a basal melting anomaly beneath
floating ice. This study presents the results of initMIP-Antarctica from 25
simulations performed by 16 international modeling groups. The submitted
results use different initial conditions and initialization methods, as well
as ice flow model parameters and reference external forcings. We find a good
agreement among model responses to the surface mass balance anomaly but
large variations in responses to the basal melting anomaly. These variations
can be attributed to differences in the extent of ice shelves and their
upstream tributaries, the numerical treatment of grounding line, and the initial ocean conditions applied, suggesting that ongoing efforts to
better represent ice shelves in continental-scale models should continue.
Fronteiras semânticas: o dialogismo das linguagens rituais pentecostais e umbandistas – uma análise das expressões gestuais
Authors: Albuquerque Júnior Valdevino De 
Published: May 2019

O espaço ritual constitui-se num locus sagrado de festa. No palco religioso, o sentimento de reconhecer-se cheio do Espírito Santo ou incorporado pelas Entidades reescreve, no próprio corpo do sujeito, a autenticidade de sua tradição mitológica. Simultaneamente, a experiência religiosa reatualiza o poder dessa tradição. E são várias as formas em que a narrativa mítica emerge, vindo à tona e tornando-se tangível à percepção e à emoção. E, neste sentido, a cultura desempenha um papel fundamental: ela é o elo a promover o encontro entre as verdades da crença e as experiências religiosas. Michel Meslin assinala que a religião só alcança o homem através das mediações culturais de seu tempo. Entre essas também variadas “mediações culturais” está a música, com seus gêneros, ritmos e uma força simbólica capaz de funcionar como chave, abrindo as portas das sensibilidades. Para além dos cânticos – mas a eles conexos –, a experiência do transe ritual é um dispositivo de mediação cultural ainda mais poderoso: um dínamo de emoções liturgicamente sacralizadas. Este sentimento religioso de alegria tem suas bases na estrutura do sistema de crenças, e, assim, até a cantiga que coadjuva e complementa os ritos, consubstancia seu status sagrado. Musicalizando o Sagrado, essa arte expressiva de fé e também de cultura potencializa ainda mais o sentimento social de pertença à comunidade religiosa do indivíduo, que também vê alimentada sua esperança de vida. Este trabalho se envereda na trilha da experiência religiosa, em seus percalços sinuosos. Nesse caminho, a intenção é compreender um pouco o funcionamento das engrenagens simbólicas que conferem sentido às manifestações performáticas vividas por pentecostais e umbandistas, em dois grupos religiosos específicos. E, ao analisar a relação entre a dinâmica ritual desses cultos e a produção de sentidos operada nas linguagens gestuais dos sujeitos da crença, refletimos sobre os diálogos semânticos rituais que, construindo experiências de espiritualidade, reconstroem também experiências de vida. É quando a divergência das cosmovisões sucumbe à convergência dos significados religiosos.
Transplantation of adipose derived stem cells overexpressing inducible nitric oxide synthase ameliorates diabetes mellitus induced erectile dysfunction in rats

Published: May 2019

Background: Erectile dysfunction is a major complication of diabetes mellitus. Adipose derived stem cells (ADSCs) has attracted much attention as a promising tool for the treatment of diabetes mellitus induced erectile dysfunction (DMED). Inducible nitric oxide synthase (iNOS) plays an important role in protecting penile tissues from fibrosis. The aim of this study was to determine the efficacy of ADSCs overexpressing iNOS on DMED in rats.
Methods: ADSCs were isolated and infected with adenovirus overexpressing iNOS (named as ADSCs-iNOS). The expression of iNOS was detected using western blot analysis and real-time PCR. Rats were randomly assigned into five groups: control group, DMED group, ADSCs group, ADSCs-EGFP group and ADSCs-iNOS group. 5×105 cells were given once via the intracorporal route. Two weeks after treatment, erectile function was assessed by electrical stimulation of the cavernous nerve. Penile tissues were obtained and evaluated at histology level.
Results: We found that ADSCs-iNOS had significantly higher expression of iNOS at mRNA and protein levels and generated more nitric oxide. ADSCs-iNOS reduced collagen I and collagen IV expression of corpus cavernosum smooth muscle cells (CCSMCs) in cell co-culture model. Transforming growth factor-β1 expression and p-Smad2/3 to Smad2/3 ratio in CCSMCs reduced following co-culture with ADSCs-iNOS. Injection of ADSCs-iNOS significantly ameliorated DMED in rats and decreased collagen/smooth muscle cell ratio of penile tissues. Moreover, elevated nitric oxide and cGMP concentrations were detected in penile tissues of ADSCs-iNOS group.
Conclusion: Taken together, ADSCs-iNOS significantly improve erectile function of DMED rats. The therapeutic effect may be achieved by increased nitric oxide generation and the suppression of collagen I and collagen IV expression in the CCSMCs to decrease penile fibrosis.

Abstract
ScAlMgO4 (SCAM) substrates with a small lattice-mismatch to GaN and c-plane cleavability are promising for fabricating high-quality free-standing GaN wafers. To reduce the cost in the fabrication of free-standing GaN wafers, the reuse of a SCAM substrate is demonstrated. By cleaving a SCAM substrate which has been already utilized for the growth of a thick GaN film by halide vapor phase epitaxy, the atomically flat surface can be obtained. The threading dislocation density of a 320 μm thick GaN film grown on this cleaved SCAM substrate is 2.4 × 107 cm−2, which is almost the same as that on a new SCAM substrate. This result indicates that a SCAM substrate can be reused for GaN growth.
