Constraining the Final Fates of Massive Stars by Oxygen and Iron Enrichment History in the Galaxy
Authors: Suzuki Akihiro , Maeda Keiichi 
Published: January 2018

Abstract
Recent observational studies of core-collapse supernovae suggest that only stars with zero-age main-sequence masses smaller than 16–

explode when they are red supergiants, producing Type IIP supernovae. This may imply that more massive stars produce other types of supernovae or they simply collapse to black holes without giving rise to bright supernovae. This failed supernova hypothesis can lead to significantly inefficient oxygen production because oxygen abundantly produced in inner layers of massive stars with zero-age main-sequence masses around 20–

might not be ejected into the surrounding interstellar space. We first assume an unspecified population of oxygen injection events related to massive stars and obtain a model-independent constraint on how much oxygen should be released in a single event and how frequently such events should happen. We further carry out one-box galactic chemical enrichment calculations with different mass ranges of massive stars exploding as core-collapse supernovae. Our results suggest that the model assuming that all massive stars with 9–

explode as core-collapse supernovae is still most appropriate in explaining the solar abundances of oxygen and iron and their enrichment history in the Galaxy. The oxygen mass in the Galaxy is not explained when assuming that only massive stars with zero-age main-sequence masses in the range of 9–17

contribute to the galactic oxygen enrichment. This finding implies that a good fraction of stars more massive than

should eject their oxygen layers in either supernova explosions or some other mass-loss processes.
Non-negative Matrix Factorization: Robust Extraction of Extended Structures

Published: January 2018

Abstract
We apply the vectorized non-negative matrix factorization (NMF) method to the post-processing of the direct imaging data of exoplanetary systems such as circumstellar disks. NMF is an iterative approach, which first creates a nonorthogonal and non-negative basis of components using the given reference images and then models a target with the components. The constructed model is then rescaled with a factor to compensate for the contribution from the disks. We compare NMF with existing methods (classical reference differential imaging method, and the Karhunen–Loève image projection algorithm) using synthetic circumstellar disks and demonstrate the superiority of NMF: with no need of prior selection of references, NMF not only can detect fainter circumstellar disks but also better preserves their morphology and does not require forward modeling. As an application to a well-known disk example, we process the archival Hubble Space Telescope STIS coronagraphic observations of HD 181327 with different methods and compare them, and NMF is able to extract some circumstellar materials inside the primary ring for the first time. In an appendix, we mathematically investigate the stability of NMF components during the iteration and the linearity of NMF modeling.

Le prix Eric Berne 2014 a été attribué à Susannah Temple, PTTA-E (retraitée), pour son développement d’un modèle original du comportement social humain. Nous avons choisi de vous présenter ce modèle par l’intermédiaire d’un texte paru dans le vol 34 n°3 juillet 2004 du TAJ. Cette version de l’article remplace celle parue dans les AAT 148, car il a été nécessaire de clarifier la théorie du modèle de fluidité fonctionnelle en rendant la terminologie plus précise dans les graphiques ainsi que dans certaines parties essentielles du texte. Vous trouverez une présentation plus complète du travail de Susannah Temple en accès libre sur le site de l’ITAA dans le script, volume 44 n°5, mai 2014 – https://www.itaaworld.org/current-back-issues-script . Ce nouveau modèle de fluidité fonctionnelle est accompagné d’un bref compte rendu des recherches qui ont mené à son développement. On explique les liens et les différences qu’il présente avec les modèles d’états du moi. On souligne aussi l’importance des concepts de fluidité fonctionnelle en éducation, ainsi que la possibilité d’utiliser ce modèle pour le développement tant personnel que professionnel des éducateurs.

La pratique de l’intervention dans la perspective de Transition comporte trois étapes incontournables : l’analyse de la demande, la conception d’un dispositif d’intervention et la conduite des groupes au sein de ce dispositif. La conception du dispositif doit prendre en compte, certes, les problèmes à traiter mais aussi le fonctionnement de la structure concernée. Dans l’exemple développé ici, le dispositif est complexe parce que le fonctionnement organisationnel l’est aussi et que l’existence de groupes distincts est une nécessité ; tout comme la mise en place de liens entre ces groupes. L’analyse de la demande ne se limite pas à une compréhension de ce qui est demandé mais consiste en une analyse du contexte, des problèmes explicites et sous-jacents tout en prenant en compte la place de celui qui exprime une commande et ses enjeux. La conduite de groupe est la manière dont l’intervenant va gérer ce qui se joue dans les espaces de travail du dispositif. Cette conduite va être déterminée par l’analyse de ce qui est à l’œuvre. Elle vise à une élaboration partagée en groupe permettant une véritable évolution des pratiques.

À travers la vignette clinique d’un patient reçu deux fois en consultation, cet article se propose d’interroger les éprouvés contretransférentiels d’effroi et de sidération en regard avec son histoire. Des traces internes traumatiques de son histoire familiale entraveraient la subjectivation, amoindriraient son insight . Comment, dans de telles conditions psychiques, un travail d’élaboration serait-il envisageable si le sujet n’a pas une reconnaissance, une acceptation, même partielle, de sa propre souffrance ?
Are “Collapse Dolines” Formed Only by Collapse?
Authors: Šušteršič France 
Published: January 2018

Razprava teče o udornicah, enem na videz najbolje definiranih površinskih kraških pojavov. Kljub temu je v literaturi zaslediti zelo različne poglede, nekateri vidiki njihove geomorfogeneze pa so bili doslej prezrti. Predvsem gre za za nadalnji razvoj globeli v kraškem površju, potem ko so prepadne stene udornice že uničene, pobočja oblikuje samo še žepasto preperevanje, denudacija pa se je zajedla že globoko pod dno nekdanjega jamskega rova. Take globeli imenuje avtor fantomske udornice. V nadalnjem obravnava pet v Sloveniji najbolj običajnih tipov udornic in jih klasificira s pomočjo terminologije splošne teorije sistemov. Zaključuje, da sam udor stropa ostaja bistven del celotnega procesa, je pa volumsko lahko zelo podrejen. The paper concerns collapse dolines, which appear to be one of the best-defined surface karst phenomena. Despite this appearance, one may find quite different views in the literature, and some the aspects of their morphogenesis have been overlooked completely. Among these aspects the most obvious is the question of the ongoing development of the closed depression. After the perpendicular walls have disappeared, the slopes are reshaped only by pocket weathering, and denudation penetrates deep below the former level of the preexisting cave floor. Dolines at this stage of development have been termed phantom collapse dolines. Five of the most common collapse doline types found in Slovenia are considered in terms of general systems theory, leading to a conclusion that cave roof collapse remains the crucial event in a collapse doline’s development. However, the collapse event itself may be relatively subdued in terms of the volume of free fallen mass involved.
Evaluation of Potential Overwinter Mortality of Age-0 Walleye and Appropriate Age-1 Sampling Gear

Published: January 2018

AbstractPotential recruitment of age-0 Walleye Sander vitreus to adults is often indexed by the relative abundance of age-0 individuals during their first summer or fall. However, relationships between age-0 and adult Walleye abundance are often weak or nonsignificant in many waters. Overwinter mortality during the first year of life has been hypothesized as an important limitation to Walleye recruitment in lakes, but limited evidence of such mortality exists, likely due to difficulties in sampling age-1 Walleye during spring. The objectives of this study were to: 1) compare results from nighttime electrofishing to index relative abundance of age-1 Walleyes with relative abundance indices of minifyke nets in four eastern South Dakota lakes; 2) determine whether size-selective mortality was occurring in those four lakes; and 3) if size-selective mortality was occurring in these lakes, determine whether that mortality was attributed to body condition. We sampled four natural lakes in eastern South Dakota 2 wk after ice-off in 2013 and 2014. Precision of nighttime electrofishing (coefficient of variation = 216.6) was greater than that estimated for minifyke nets (coefficient of variation = 338.5) across both years. We detected no differences in length-frequency distributions of collected spring age-1 Walleye between the two gears. Age-0 fall relative abundance indices from electrofishing were significantly greater (P &lt; 0.01) than spring age-1 nighttime electrofishing indices of relative abundance at three of the four study lakes, indicating that overwinter mortality may occur at a substantial rate during the first year of life for Walleye in these systems. Quantile–quantile regression plots showed evidence of size-selective mortality in three of four lakes sampled. However, body condition of age-0 Walleye appeared to have little to no influence on overwinter mortality. Instead, we suggest that smaller-sized walleye may be more vulnerable to overwinter predation. Collectively, these results provide evidence of previously hypothesized overwinter mortality within the first year for Walleye and indicate possibilities for indexing potential adult recruitment of Walleye just after this critical period.
La vallée engloutie (Volume 2 : catalogue des sites)
Authors: Gaborit Justine 
Published: January 2018

La construction sur l’Euphrate des barrages turcs et syriens a entraîné la disparition d’un tiers des sites hellénistiques, romains et byzantins de la vallée ; elle a modifié le rôle que le Moyen-Euphrate jouait depuis des millénaires comme axe principal de circulation et d’échanges entre la Méditerranée et la Mésopotamie. Cet essai de géographie historique se propose de poursuivre la synthèse que René Dussaud avait consacrée aux rives de l’Euphrate dans la Topographie historique de la Syrie antique et médiévale, publiée en 1927. En croisant différentes sources textuelles et documentaires, des écrits des géographes antiques aux images satellitaires, cette étude, accompagnée de nombreuses illustrations, met en valeur les dynamiques géographiques et historiques qui ont marqué l’occupation de la vallée depuis la fin du IVe s. av. J.-C. jusqu’au VIIe s. (volume 1).Complément indispensable de l’étude d’ensemble, le catalogue (volume 2) présente 212 notices, accompagnées d’une très riche documentation graphique et photographique sur les sites archéologiques de la vallée : centres urbains, villages, forteresses, églises, monastères, nécropoles du Moyen-Euphrate durant les périodes hellénistique, romaine et byzantine. Il permet de parcourir les deux rives du fleuve, de Zeugma à Doura-Europos : ainsi se trouve rassemblée la somme des données archéologiques représentatives des profondes mutations intervenues entre la colonisation séleucide et le siècle de Justinien.

Abstract. Most prior field studies of new particle formation (NPF) have been performed
at or near ground level, leaving many unanswered questions regarding the
vertical extent of NPF. To address this, we measured concentrations of 11–16 nm
diameter particles from ground level to 1000 m during the 2013
New Particle Formation Study at the Atmospheric Radiation Measurement
Southern Great Plains site in Lamont, Oklahoma. The measurements were
performed using a tethered balloon carrying two condensation particle
counters that were configured for two different particle cut-off diameters.
These observations were compared to data from three scanning mobility
particle sizers at the ground level. We observed that 11–16 nm diameter
particles were generated at the top region of the boundary layer, and were
then rapidly mixed throughout the boundary layer. We also estimate liquid
water content of nanoparticles using ground-based measurements of particle
hygroscopicity obtained with a Humidified Tandem Differential Mobility
Analyzer and vertically resolved relative humidity (RH) and temperature
measured with a Raman lidar. Our analyses of these observations lead to the
following conclusions regarding nanoparticles formed during NPF events at
this site: (1) ground-based observations may not always accurately represent
the timing, distribution, and meteorological conditions associated with the
onset of NPF; (2) nanoparticles are highly hygroscopic and typically contain
up to 50 % water by volume, and during conditions of high RH combined with
high particle hygroscopicity, particles can be up to 95 % water by volume;
(3) increased liquid water content of nanoparticles at high RH greatly
enhances the partitioning of water-soluble species like organic acids into
ambient nanoparticles.
Sensitivity of woody carbon stocks to bark investment strategy in Neotropical savannas and forests
Authors: Trugman Anna T. , Medvigy David , Hoffmann William A. , Pellegrini Adam F. A. 
Published: January 2018

Abstract. Fire frequencies are changing in Neotropical savannas and
forests as a result of forest fragmentation and increasing drought. Such
changes in fire regime and climate are hypothesized to destabilize tropical
carbon storage, but there has been little consideration of the widespread
variability in tree fire tolerance strategies. To test how aboveground
carbon stocks change with fire frequency and composition of plants with
different fire tolerance strategies, we update the Ecosystem Demography
model 2 (ED2) with (i) a fire survivorship module based on tree bark
thickness (a key fire-tolerance trait across woody plants in savannas and
forests), and (ii) plant functional types representative of trees in the
region. With these updates, the model is better able to predict how fire
frequency affects population demography and aboveground woody carbon.
Simulations illustrate that the high survival rate of thick-barked, large
trees reduces carbon losses with increasing fire frequency, with high
investment in bark being particularly important in reducing losses in the
wettest sites. Additionally, in landscapes that frequently burn, bark
investment can broaden the range of climate and fire conditions under which
savannas occur by reducing the range of conditions leading to either
complete tree loss or complete grass loss. These results highlight that
tropical vegetation dynamics depend not only on rainfall and changing fire
frequencies but also on tree fire survival strategy. Further, our results
indicate that fire survival strategy is fundamentally important in
regulating tree size demography in ecosystems exposed to fire, which
increases the preservation of aboveground carbon stocks and the coexistence
of different plant functional groups.
Hydrometeorological conditions preceding wildfire, and the subsequent burning of a fen watershed in Fort McMurray, Alberta, Canada

Abstract. The destructive nature of the  ∼  590 000 ha Horse river wildfire in the Western Boreal Plain (WBP), northern Alberta, in May of 2016 motivated the investigation of the hydrometeorological conditions that preceded the fire. Historical climate and field hydrometeorological data from a moderate-rich fen watershed were used to (a) identify whether the spring 2016 conditions were outside the range of natural variability for WBP climate cycles, (b) explain the observed patterns in burn severity across the watershed, and (c) identify whether fall and winter moisture signals observed in peatlands and lowland forests in the region are indicative of wildfire. Field hydrometeorological data from the fen watershed confirmed the presence of cumulative moisture deficits prior to the fire. Hydrogeological investigations highlighted the susceptibility of fen and upland areas to water table and soil moisture decline over rain-free periods (including winter), due to the watershed's reliance on supply from localized flow systems originating in topographic highs. Subtle changes in topographic position led to large changes in groundwater connectivity, leading to greater organic soil consumption by fire in wetland margins and at high elevations. The 2016 spring moisture conditions measured prior to the ignition of the fen watershed were not illustrated well by the Drought Code (DC) when standard overwintering procedures were applied. However, close agreement was found when default assumptions were replaced with measured duff soil moisture recharge and incorporated into the overwintering DC procedure. We conclude that accumulated moisture deficits dating back to the summer of 2015 led to the dry conditions that preceded the fire. The infrequent coinciding of several hydrometeorological conditions, including low autumn soil moisture, a modest snowpack, lack of spring precipitation, and high spring air temperatures and winds, ultimately led to the Horse river wildfire spreading widely and causing the observed burn patterns. Monitoring soil moisture at different land classes and watersheds would aid management strategies in the production of more accurate overwintered DC calculations, providing fire management agencies early warning signals ahead of severe spring wildfire seasons.
Black-Box Fuzzy Identification of a Nonlinear Hydrogen Fuel Cell Model
Authors: Bertone Ana Maria Amarillo , Martins Jefferson Beethoven , Yamanaka Keiji 
Published: January 2018

A fuzzy identification of the dynamical system model is developed upon a data generated by a software simulator of a hydrogen fuel cell. The data presents a black box model, just composed by inputs and outputs, carry no additional information, and showing a strong nonlinear behavior. The choice for a fuzzy identification is based on the data features, and the malleability of the mathematical fuzzy technique. This approach allows to accomplish the objectives of the research, among which, the validation of the method for it used in other industrial problems. The dynamic system identification process is performed using a fuzzy clustering through the Gustafson and Kessel algorithm, and a Takagi Sugeno fuzzy inference method. Validation tests are performed in terms of the 4-fold technique, confirming the lack of the data over-training. These results make the fuzzy approach looks as a promising tool for black-box identification of non linear dynamic systems.

Realisering van het recht op onaantastbaarheid van het lichaam door middel van wetgeving
In deze bijdrage wordt het nut en de meerwaarde van het recht op de onaantastbaarheid van het lichaam onderzocht, alsmede de grondrechtelijke randvoorwaarden die van belang zijn bij de realisering van het recht op de onaantastbaarheid van het lichaam. Dit wordt onder meer in het licht geplaatst van de rechtspraktijk en huidige en toekomstige dilemma’s en technologische ontwikkelingen. De meerwaarde van artikel 11 Grondwet wordt, met name ten opzichte van artikel 10 Grondwet (bescherming persoonlijke levenssfeer), wel als beperkt ingeschat omdat beide bepalingen ten aanzien van de onaantastbaarheid van het menselijk lichaam juridisch dezelfde bescherming bieden. De vraag is echter of dat terecht is, nu artikel 11 Grondwet het menselijk lichaam expliciet als rechtsobject beschermt. Technologische ontwikkelingen, waarbij enerzijds het menselijk lichaam steeds meer maakbaar wordt en aan veranderingen kan worden onderworpen. Juist in die context heeft het recht op onaantastbaarheid van het menselijk lichaam betekenis en urgentie. Anderzijds roepen ook de steeds grotere medische mogelijkheden en de hoge kosten waarmee dat gepaard gaat vragen op. Het belang van de bescherming die artikel 11 Grondwet biedt, is daarmee juist in het huidige tijdsgewricht van belang.

Lichamelijke integriteit bij de ontwikkeling van de medische wetenschap: elementen uit de belangenafweging
In deze bijdrage wordt de belangenafweging onder de loep genomen die volgens de Nederlandse wetgever moet worden gemaakt om de integriteit van het lichaam te beperken en te beschermen bij de ontwikkeling van de medische wetenschap. Het toepasselijke juridisch kader bestaat uit het vereiste van toestemming van de betrokkene, het verbod op onevenredige financiële vergoeding, de medisch-ethische toetsing van onder meer de noodzakelijkheid en de bovengrens aan de belasting en risico’s. Naast een bespreking van deze vereisten wordt ingegaan op de klaarblijkelijke wens van de wetgever om aan te sluiten bij bestaand recht en om te kiezen voor een systeem met een sterk procedureel karakter in combinatie met open normen.

Bouwen in een circulaire stad
In deze bijdrage wordt onderzocht of het huidige en toekomstige omgevingsrechtelijk instrumentarium voldoende mogelijkheden en/of stimulansen biedt om volledig circulaire steden mogelijk te maken. Daarbij komen de volgende onderwerpen aan de orde. Eerst wordt ingegaan op de eisen die aan de circulariteit van bouwwerken kunnen worden gesteld in de ontwerpfase. Besproken wordt in hoeverre de ambities van gemeentelijke ‘koplopers’ kunnen worden vormgegeven door strenge(re) eisen te stellen aan het materiaalgebruik bij nieuwbouw. Vervolgens wordt ingegaan op de vraag in hoeverre circulariteit bij bestaande bouw kan worden bereikt. Daarbij gaat het zowel om het planologisch instrumentarium om leegstand tegen te gaan, als om de eisen die kunnen worden gesteld aan verantwoord materiaalgebruik bij renovatie. Daarna komen de mogelijkheden in de sloopfase van een bouwwerk aan de orde: in hoeverre kunnen eisen worden gesteld ten aanzien van de scheiding van waardevol bouw- en sloopmateriaal?
