Evolution of the Transverse Density Structure of Oscillating Coronal Loops Inferred by Forward Modeling of EUV Intensity
Authors: Goddard C. R. , Antolin P. , Pascoe D. J. 
Published: August 2018

Abstract
Recent developments in the observation and modeling of kink oscillations of coronal loops have led to heightened interest over the last few years. The modification of the Transverse Density Profile (TDP) of oscillating coronal loops by nonlinear effects, particularly the Kelvin–Helmholtz Instability (KHI), is investigated. How this evolution may be detected is established, in particular, when the KHI vortices may not be observed directly. A model for the loop’s TDP is used that includes a finite inhomogeneous layer and homogeneous core, with a linear transition between them. The evolution of the loop’s transverse intensity profile from numerical simulations of kink oscillations is analyzed. Bayesian inference and forward modeling techniques are applied to infer the evolution of the TDP from the intensity profiles, in a manner that may be applied to observations. The strongest observational evidence for the development of the KHI is found to be a widening of the loop’s inhomogeneous layer, which may be inferred for sufficiently well resolved loops, i.e., >15 data points across the loop. The main signatures when observing the core of the loop (for this specific loop model) during the oscillation are a widening inhomogeneous layer, decreasing intensity, an unchanged radius, and visible fine transverse structuring when the resolution is sufficient. The appearance of these signatures are delayed for loops with wider inhomogeneous layers, and quicker for loops oscillating at higher amplitudes. These cases should also result in stronger observational signatures, with visible transverse structuring appearing for wide loops observed at the resolution of current instruments.

Abstract
We present improved fits to our treatment of suppression of dielectronic recombination at intermediate densities. At low densities, most recombined excited states eventually decay to the ground state, and therefore the total dielectronic recombination rate to all levels is preserved. At intermediate densities, on the other hand, collisions can lead to ionization of higher-lying excited states, thereby suppressing the dielectronic recombination rate. The improved suppression factors presented here, although highly approximate, allow summed recombination rate coefficients to be used to intermediate densities. There have been several technical improvements to our previously presented fits. For H- through B-like ions the activation log densities have been adjusted to better reproduce existing data. For B-, C-, Al-, and Si-like ions secondary autoionization is now included. The treatment of density discontinuity in electron excitations out of ground state H-, He-, and Ne-like ions has been improved. These refined dielectronic recombination suppression factors are used in the most recent version of the plasma simulation code Cloudy. We show how the ionization and emission spectrum change when this physics is included. Although these suppression factors improve the treatment of intermediate densities, they are highly approximate and are not a substitution for a complete collisional-radiative model of the ionization balance.

Abstract
We present the results of a ground-based observing campaign designed to produce the first homogeneous census of the population of the broadest (FWHM ≥ 6 Å) diffuse interstellar bands (DIBs) in the Galaxy. New low-resolution optical spectra for 21 sightlines spanning a reddening range of three magnitudes, using stars of spectral types O7 through A3, were examined together with corresponding higher-resolution echelle spectra. A new pipeline developed for the reduction and analysis of the low-resolution spectra is presented. Of the 34 broad features reported in the literature, 22 are covered in this survey. Of those 22, 9 are confirmed as broad DIBs, 2 are rejected, and the remaining 11 are uncertain, due to severe blending with stellar and/or telluric lines. No new broad DIBs are identified. New homogeneous measurements of the strength of the broad 6177 Å DIB are compared with the corresponding strengths of five narrower DIBs known to trace different phases of the diffuse ISM: the 4963 Å C2-DIB (which can reside in diffuse molecular gas) and the 5780, 5797, 6284, and 6613 Å DIBs (which primarily trace atomic gas). The 6177 Å DIB correlates quite well with the 5780 and 6284 Å DIBs but shows no correlation with the 4963 Å C2-DIB—suggesting that its carrier is found primarily in the atomic gas.

Abstract
This paper describes the second data release (DR2) of the Beijing–Arizona Sky Survey (BASS). BASS is an imaging survey covering a 5400 deg2 footprint in the g and r bands using the 2.3 m Bok telescope. DR2 includes the observations through 2017 July obtained by BASS and by the Mayall z-band Legacy Survey (MzLS), which used the 4 m Mayall telescope to observe the same footprint. BASS and MzLS have completed 72% and 76% of their observations. The two surveys will be served for the spectroscopic targeting of the upcoming Dark Energy Spectroscopic Instrument. Both BASS and MzLS data are reduced by the same pipeline. We have updated the basic data reduction and photometric calibrations in DR2. In particular, source detections are performed on stacked images, and photometric measurements are co-added from single-epoch images based on these sources. The median 5σ point-source depths after Galactic extinction corrections are 24.05, 23.61, and 23.10 mag for the g, r, and z bands, respectively. The DR2 data products include stacked images, co-added catalogs, and single-epoch images and catalogs. The BASS website (http://batc.bao.ac.cn/BASS/) provides detailed information and links to download the data.
A Catalog of Merging Dwarf Galaxies in the Local Universe
Authors: Paudel Sanjaya , Smith Rory , Yoon Suk Jin , Calderón-Castillo Paula , Duc Pierre-Alain 
Published: August 2018

Abstract
We present the largest publicly available catalog of interacting dwarf galaxies. It includes 177 nearby merging dwarf galaxies of stellar mass M
* < 1010
M
⊙ and redshifts z < 0.02. These galaxies are selected by visual inspection of publicly available archival imaging from two wide-field optical surveys (SDSS-III and the Legacy Survey), and they possess low-surface-brightness features that are likely the result of an interaction between dwarf galaxies. We list UV and optical photometric data that we use to estimate stellar masses and star formation rates. So far, the study of interacting dwarf galaxies has largely been done on an individual basis, and lacks a sufficiently large catalog to give statistics on the properties of interacting dwarf galaxies, and their role in the evolution of low-mass galaxies. We expect that this public catalog can be used as a reference sample to investigate the effects of the tidal interaction on the evolution of star formation, and the morphology/structure of dwarf galaxies. Our sample is overwhelmingly dominated by star-forming galaxies, and they are generally found significantly below the red sequence in the color–magnitude relation. The number of early-type galaxies is only 3 out of 177. We classify them, according to observed low-surface-brightness features, into various categories including shells, stellar streams, loops, antennae, or simply interacting. We find that dwarf–dwarf interactions tend to prefer the low-density environment. Only 41 out of the 177 candidate dwarf–dwarf interaction systems have giant neighbors within a sky-projected distance of 700 kpc and a line-of-sight radial velocity range ±700 km s−1, and compared to the LMC–SMC, they are generally located at much larger sky-projected distances from their nearest giant neighbors.
Sang des bâtards, sang de la noblesse : à propos des « contextes durables » en anthropologie historique de la parenté
Authors: Steinberg Sylvie 
Published: August 2018

Dans un article publié en 2015 dans les Annales HSS sous le titre « La France profonde. Relations de parenté et alliances matrimoniales (xvie-xviiie siècle) », Gérard Delille proposait de considérer les figures « structurantes » de la parenté qu’il observait à partir de données massives et denses recueillies sur les alliances conclues au fil de plusieurs générations de provinciaux sous l’Ancien Régime comme des « contextes durables ». Ce faisant, il répondait à la critique classique adressée à l’anthropologie structurale de la parenté que celle-ci ne prenait pas suffisamment en compte les dynamiques diachroniques en privilégiant l’observation des structures pérennes et des faits immuables. Cet article reprend cette notion de « contexte durable » pour éclairer les permanences dans la condition des bâtards de la noblesse entre le xvie et le xviie siècle. Si les bâtards continuent d’être si importants dans les lignages nobles du début de l’époque moderne, n’est-ce pas imputable à l’inflexion patrilinéaire de la transmission de la noblesse ainsi qu’à l’exaltation du sang qui semble caractériser la noblesse sur la longue durée ? Au regard des recherches récentes sur l’histoire de la filiation et sur l’histoire du sang, cette hypothèse est ici discutée par une historicisation des liens de filiation et de l’imaginaire du sang en tant que supposé « substrat » biologique de la filiation depuis la fin du Moyen Âge jusqu’à la fin du xviie siècle. À un autre niveau d’analyse, la substitution du terme « contexte durable » au terme « structure » ouvre sur d’autres questionnements : questionnement historiographique sur le « jeu d’échelles » des temporalités où prennent place les faits historiques, questionnement sur les attendus, les questionnaires et les horizons de l’anthropologie historique de la parenté.
Généalogie, parenté et histoire sociale. Composition et re-compositions des familles en milieu colonial, Santiago du Chili (mi-XVIe-fin XVIIe siècles)
Authors: Zuñiga Jean-Paul 
Published: August 2018

Cette contribution cherche à mettre le concept de « système de famille européen » à l’épreuve du contexte colonial hispano-américain au xviie siècle. Le cas hispano-américain se singularise à cet égard par une grande diversité de situations, montrant la coexistence de modèles d’élite contrastant fortement avec ceux des autres groupes sociaux. Face à la centralité de la question patrimoniale comme moteur de l’alliance pour les premiers, les groupes plus modestes déploient en effet une grande diversité de pratiques et de grammaires de l’emparentement. Le « faire famille » se décline ainsi socialement. Cet article met en question la pertinence de fonder cette divergence sur la différence ethnoculturelle – c’est-à-dire de la coprésence, dans les mondes coloniaux, de modèles européens et extra-européens – et s’interroge sur la validité même de la notion de modèle, aussi bien dans le contexte américain qu’européen
Système de parenté et histoire sociale : éléments pour un débat
Authors: Haddad Elie 
Published: August 2018

Parmi les travaux récents en histoire de la parenté, celui de Gérard Delille se distingue par son ambition : comprendre le système européen de la parenté et de l’alliance entre Moyen Âge et époque moderne, à la croisée de l’histoire et de l’anthropologie. Cet article revient sur les principaux éléments de ce système et sur la conception de la parenté qui le fonde, avant de présenter les grandes figures de l’alliance – bouclages consanguins, échanges entre lignées alternées, renchaînements d’alliances – qui y sont à l’œuvre, et ce pour interroger la relation entre ce système d’alliance et le système de parenté plus général, qui n’est pas exempte de tensions. L’article discute alors la place de la parenté par rapport aux autres structures sociales et les manières d’envisager les relations entre structures et contextes.
Importance of seasonally resolved oceanic emissions for bromoform delivery from the tropical Indian Ocean and west Pacific to the stratosphere
Authors: Fiehn Alina , Quack Birgit , Stemmler Irene , Ziska Franziska , Krüger Kirstin 
Published: August 2018

Abstract. Oceanic very short-lived substances (VSLSs), such as bromoform
(CHBr3), contribute to stratospheric halogen loading and, thus, to
ozone depletion. However, the amount, timing, and region of bromine delivery
to the stratosphere through one of the main entrance gates, the Indian summer
monsoon circulation, are still uncertain. In this study, we created two
bromoform emission inventories with monthly resolution for the tropical
Indian Ocean and west Pacific based on new in situ bromoform measurements and
novel ocean biogeochemistry modeling. The mass transport and atmospheric
mixing ratios of bromoform were modeled for the year 2014 with the particle
dispersion model FLEXPART driven by ERA-Interim reanalysis. We compare
results between two emission scenarios: (1) monthly averaged and (2) annually averaged
emissions. Both simulations reproduce the atmospheric distribution of
bromoform from ship- and aircraft-based observations in the boundary layer
and upper troposphere above the Indian Ocean reasonably well. Using monthly resolved emissions, the main oceanic source regions for the
stratosphere include the Arabian Sea and Bay of Bengal in boreal summer and
the tropical west Pacific Ocean in boreal winter. The main stratospheric
injection in boreal summer occurs over the southern tip of India associated
with the high local oceanic sources and strong convection of the summer
monsoon. In boreal winter more bromoform is entrained over the west Pacific
than over the Indian Ocean. The annually averaged stratospheric injection of
bromoform is in the same range whether using monthly averaged or annually averaged
emissions in our Lagrangian calculations. However, monthly averaged emissions
result in the highest mixing ratios within the Asian monsoon anticyclone in
boreal summer and above the central Indian Ocean in boreal winter, while
annually averaged emissions display a maximum above the west Indian Ocean in
boreal spring. In the Asian summer monsoon anticyclone bromoform atmospheric
mixing ratios vary by up to 50 % between using monthly averaged and annually
averaged oceanic emissions. Our results underline that the seasonal and
regional stratospheric bromine injection from the tropical Indian Ocean and
west Pacific critically depend on the seasonality and spatial distribution
of the VSLS emissions.
Developing a global operational seasonal hydro-meteorological forecasting system: GloFAS-Seasonal v1.0

Published: August 2018

Abstract. Global overviews of upcoming flood and drought events are
key for many applications, including disaster risk reduction initiatives.
Seasonal forecasts are designed to provide early indications of such events
weeks or even months in advance, but seasonal forecasts for hydrological
variables at large or global scales are few and far between. Here, we present
the first operational global-scale seasonal hydro-meteorological forecasting
system: GloFAS-Seasonal. Developed as an extension of the Global Flood
Awareness System (GloFAS), GloFAS-Seasonal couples seasonal meteorological
forecasts from ECMWF with a hydrological model to provide openly available
probabilistic forecasts of river flow out to 4 months ahead for the global
river network. This system has potential benefits not only for disaster risk
reduction through early awareness of floods and droughts, but also for
water-related sectors such as agriculture and water resources management, in
particular for regions where no other forecasting system exists. We describe
the key hydro-meteorological components and computational framework of
GloFAS-Seasonal, alongside the forecast products available, before discussing
initial evaluation results and next steps.
Detecting dominant changes in irregularly sampled multivariate water quality data sets
Authors: Lehr Christian , Dannowski Ralf , Kalettka Thomas , Merz Christoph , Schröder Boris , Steidl Jörg , Lischeid Gunnar 
Published: August 2018

Abstract. Time series of groundwater and stream water quality often exhibit substantial
temporal and spatial variability, whereas typical existing monitoring data
sets, e.g. from environmental agencies, are usually characterized by
relatively low sampling frequency and irregular sampling in space and/or
time. This complicates the differentiation between anthropogenic influence
and natural variability as well as the detection of changes in water quality
which indicate changes in single drivers. We suggest the new term “dominant
changes” for changes in multivariate water quality data which concern
(1) multiple variables, (2) multiple sites and (3) long-term patterns and
present an exploratory framework for the detection of such dominant changes
in data sets with irregular sampling in space and time. Firstly, a non-linear
dimension-reduction technique was used to summarize the dominant
spatiotemporal dynamics in the multivariate water quality data set in a few
components. Those were used to derive hypotheses on the dominant drivers
influencing water quality. Secondly, different sampling sites were compared
with respect to median component values. Thirdly, time series of the
components at single sites were analysed for long-term patterns. We tested
the approach with a joint stream water and groundwater data set quality
consisting of 1572 samples, each comprising sixteen variables, sampled with a
spatially and temporally irregular sampling scheme at 29 sites in northeast
Germany from 1998 to 2009. The first four components were interpreted as
(1) an agriculturally induced enhancement of the natural background level of
solute concentration, (2) a redox sequence from reducing conditions in deep
groundwater to post-oxic conditions in shallow groundwater and oxic
conditions in stream water, (3) a mixing ratio of deep and shallow
groundwater to the streamflow and (4) sporadic events of slurry application
in the agricultural practice. Dominant changes were observed for the first
two components. The changing intensity of the first component was interpreted
as response to the temporal variability of the thickness of the unsaturated
zone. A steady increase in the second component at most stream water sites
pointed towards progressing depletion of the denitrification capacity of the
deep aquifer.
Application to Occupy

Urban Animators: Living Laboratory (UA:LL) was a public art research project that actively engaged with the RMIT University New Academic Street capital works project, undertaken at the Melbourne city campus from 2015-2017. The construction site and the surrounding campus were envisaged as a living laboratory encouraging research that engaged with the internal infrastructure, process and community of RMIT University.As curator of the UA:LL public art program I created a framework that encouraged collaboration, provocation, solidarity and exchange amongst RMIT University students, staff and alumni. This was achieved through the process of open expression of interests, learning and teaching, invited artists and industry research partnerships all resulting in public artworks embedded in the construction zone. The artistic installations included public artworks on construction hoardings and projections within the constriction zone that positively activated the site condition and helped mitigate the disruption occurring on the campus.As a curator, artist and designer I proposed a spatial curatorial proposition to the city via a public art installation titled ‘Gantry Section D’ as part of the UA:LL program. ‘Gantry Section D’ was the result of an intensive period of practice based investigation into the condition created when a city is undergoing transformation.
Public Space in the New Urban Agenda. The Challenge of Implementation
Authors: Elmlund Peter , Haas Tigran , Mehaffy Michael 
Published: August 2018

The New Urban Agenda – the landmark 2016 agreement for sustainable urban development that has now been adopted by consensus by 193 nations – contains no fewer than nine paragraphs extensively discussing the importance of public space. Among other things, the document describes public spaces as “drivers of social and economic development,” “enhancing safety and security, favoring social and inter-generational interaction and the appreciation of diversity” and “promoting walkability and cycling towards improving health and well-being.” There is also language on the role of public space in enhancing ecological sustainability and resilience, on equity and opportunity, on connectivity and social inclusion, on cultural expression and dialogue, and on broader human development (United Nations, 2017).
We the people, We the public space. An interactive exhibition at the 9th World Urban Forum
Authors: Bravo Luisa , Francia Valerio 
Published: August 2018

At the Ninth session of the World Urban Forum, convened by UN-Habitat, the United Nations Human Settlements Programme, held on 7-13 February 2018 in Kuala Lumpur, Malaysia, City Space Architecture was selected to be part of the event as an exhibitor: it was included in the exhibition area, held at the main venue of the Forum, the Kuala Lumpur Convention Centre, besides the Petronas Towers, as the only Italian exhibitor, together with 200 selected exhibitors from 50 countries.The exhibition space hosted the exhibition ‘We the people, We the public space’: recalling the well-known United Nations’ campaign ‘We the people’ for the Global Goals[1] launched in 2015, the exhibition was intended to stress the concept that people and public space, intended as the space for democracy, social justice and equity, are strongly intertwined, so that talking about people is the same thing as talking about public space. The UN commitment ‘Leaving no one behind’[2] (United Nations, 2016 and 2017) for inclusive development is strictly related to people and therefore to public space: it is a demand for country leaders to prioritise the needs of those most marginalised and disadvantaged, facing poverty and discrimination, so that the goals for sustainable development are delivered by 2030[3].
