Abstract
High-resolution Hubble Space Telescope (HST) image analysis of the MOA-2008-BLG-310 microlens system indicates that the excess flux at the location of the source found in the discovery paper cannot primarily be due to the lens star because it does not match the lens–source relative proper motion,

, predicted by the microlens models. This excess flux is most likely to be due to an unrelated star that happens to be located in close proximity to the source star. Two epochs of HST observations indicate proper motion for this blend star that is typical of a random bulge star but is not consistent with a companion to the source or lens stars if the flux is dominated by only one star, aside from the lens. We consider models in which the excess flux is due to a combination of an unrelated star and the lens star, and this yields a 95% confidence level upper limit on the lens star brightness of

and

. A Bayesian analysis using a standard Galactic model and these magnitude limits yields a host star mass of

and a planet mass of

at a projected separation of

au. This result illustrates that excess flux in a high-resolution image of a microlens–source system need not be due to the lens. It is important to check that the lens–source relative proper motion is consistent with the microlensing prediction. The high-resolution image analysis techniques developed in this paper can be used to verify the WFIRST exoplanet microlensing survey mass measurements.
MHD Simulations of the Eruption of Coronal Flux Ropes under Coronal Streamers
Authors: Fan Yuhong 
Published: July 2017

Abstract
Using three-dimensional magnetohydrodynamic (MHD) simulations, we investigate the eruption of coronal flux ropes underlying coronal streamers and the development of a prominence eruption. We initialize a quasi-steady solution of a coronal helmet streamer, into which we impose at the lower boundary the slow emergence of a part of a twisted magnetic torus. As a result, a quasi-equilibrium flux rope is built up under the streamer. With varying streamer sizes and different lengths and total twists of the flux rope that emerges, we found different scenarios for the evolution from quasi-equilibrium to eruption. In the cases with a broad streamer, the flux rope remains well confined until there is sufficient twist such that it first develops the kink instability and evolves through a sequence of kinked, confined states with increasing height until it eventually develops a “hernia-like” ejective eruption. For significantly twisted flux ropes, prominence condensations form in the dips of the twisted field lines due to runaway radiative cooling. Once formed, the prominence-carrying field becomes significantly non-force-free due to the weight of the prominence, despite having low plasma β. As the flux rope erupts, the prominence erupts, showing substantial draining along the legs of the erupting flux rope. The prominence may not show a kinked morphology even though the flux rope becomes kinked. On the other hand, in the case with a narrow streamer, the flux rope with less than one wind of twist can erupt via the onset of the torus instability.

Abstract
Using data from the Magnetospheric Multiscale (MMS) and Cluster missions obtained in the solar wind, we examine second-order and fourth-order structure functions at varying spatial lags normalized to ion inertial scales. The analysis includes direct two-spacecraft results and single-spacecraft results employing the familiar Taylor frozen-in flow approximation. Several familiar statistical results, including the spectral distribution of energy, and the sale-dependent kurtosis, are extended down to unprecedented spatial scales of ∼6 km, approaching electron scales. The Taylor approximation is also confirmed at those small scales, although small deviations are present in the kinetic range. The kurtosis is seen to attain very high values at sub-proton scales, supporting the previously reported suggestion that monofractal behavior may be due to high-frequency plasma waves at kinetic scales.
Sur l’épistémologie de la recherche en histoire des pratiques pédagogiques de terrain en éducation physique et sportive
Authors: Auvray Emmanuel 
Published: July 2017

L’historiographie de l’éducation physique et sportive (EPS) montre que les pratiques pédagogiques de terrain sont encore méconnues pour de multiples raisons qui tiennent notamment à la disponibilité, à la nature et aux traitements des sources mobilisées pour formaliser cette histoire qui « reste à faire ». Or cette histoire permet de lever le voile sur la manière dont les enseignants d’EPS ont appliqué au quotidien le curriculum prescrit. Toutefois, l’écriture historique des pratiques pédagogiques effectives est complexe à plus d’un titre dans la mesure où elle repose sur différents types d’acteurs connus (leaders ou non) ou anonymes et diverses sources indiciaires, à analyser, entre les archives imprimées, orales, iconographiques et filmiques. Cette étude épistémologique sur l’écriture historique des pratiques pédagogiques effectives chez différents niveaux d’acteurs de terrain de l’EPS a pour objectifs d’identifier, tout en les critiquant, les corpus mobilisés, les modes de production de la connaissance, les fondements de cette connaissance ainsi que la dynamique de cette production afin de déterminer leur origine logique, leur valeur et leur portée objective. Ce travail repose sur l’analyse des principaux travaux universitaires ayant pour objet l’histoire des pratiques professorales effectives en EPS chez les acteurs de terrain anonymes, connus ou leaders. Force est de constater que ces recherches sont relativement disparates et hétérogènes.
Influence des représentations culturelles dans l’apprentissage de la nage à Paris et Canton
Authors: Schwob Valérie , During Bertrand 
Published: July 2017

Cet article a pour objet de montrer que les représentations culturelles influencent la transmission d’une technique du corps (Mauss) : l’apprentissage de la nage. Nous avons mis en évidence l’existence de représentations culturelles de l’eau. Celles-ci participent à l’enseignement de la nage en Chine et en France. La méthodologie employée pour cette recherche s’appuie sur une approche comparative de l’enseignement de techniques du corps (Mauss, 1950) au travers de questionnaires, d’entretiens et d’observations. L’originalité de ce propos repose sur la démarche d’un questionnement culturel des apprentissages moteurs. Ceux-ci sont généralement abordés dans leurs aspects techniques, et non pas au regard d’un vécu culturel et des représentations. Pourtant, l’influence de la mondialisation des techniques sportives (Terret, 2011) sur les pratiques physiques interroge la spécificité des pratiques culturelles. En natation, les positionnements culturel et éducatif reflètent les représentations singulières.
Percepción preliminar de los marcos regulatorios del sistema universitario iberoamericano: algunos avances investigativos
Authors: Contreras Francisco Ganga 
Published: July 2017

La universidad es una institución del medievo, de carácter social y altamente respetada por las respectivas comunidades que la acogen, que ha demostrado una versatilidad a toda prueba al mantenerse vigente por tantos años, no obstante, ésta debe ser capaz de expresar su naturaleza comunitaria en la capacidad de estar al servicio de la sociedad que le dio vida, y por ende, requiere estar sujeta a los marcos establecidos para asegurar su adecuado funcionamiento.Tomando en cuenta esta realidad, se ha estimado conveniente realizar una indagación primaria cuya finalidad central es conocer la percepción que tienen los entendidos en gestión universitaria respecto al marco regulatorio en Iberoamérica. De lo que se trata definitivamente es de la presentación de avances preliminares, y para alcanzar este objetivo se procedió a la aplicación de una encuesta con preguntas cerradas a una muestra no probabilística e intencionada de 149 expertos pertenecientes a diferentes universidades iberoamericanas; siendo ocho variables que se analizan a partir de un cuestionario auto aplicado a diferentes funcionarios universitarios.

Abstract. MicroRNAs (miRNAs) can coordinate the main pathways involved in innate and adaptive immune responses by regulating gene expression. To explore the resistance to mastitis in cows, miR-144-5p and miR-130b-5p were identified in bovine mammary gland tissue and 14 potential target genes belonging to the chemokine signaling pathway, the arginine and proline metabolism pathway and the mRNA surveillance pathway were predicted. Subsequently, we estimated the relative expression of miR-144-5p and miR-130b-5p in cow mammary tissues by using stem-loop quantitative real-time polymerase chain reaction. The results showed that the relative expression of miR-144-5p and miR-130b-5p in the mastitis-infected mammary tissues (n = 5) was significantly downregulated 0.14-fold (p < 0. 01) and upregulated 3.34-fold (p < 0. 01), respectively, compared to healthy tissues (n = 5). Our findings reveal that miR-144-5p and miR-130b-5p may have important roles in resistance to mastitis in dairy cattle.

Published: July 2017

À l’occasion du 50e anniversaire de la Division de la gestion de documents et des archives de l’Université de Montréal, Claude Minotto, son ancien directeur nous livre ses réflexions. Il nous présente d’abord un bref plaidoyer en faveur de la diversité, car à ses yeux, une fois les conditions de préservation assurées, l’important est l’utilité de ce qui est conservé. Il utilise l’expression qui sert d’entête au site Internet de la DGDA comme préambule à la présentation de divers défis qu’ont amené les changements technologiques de la première décennie des années 2000 à la discipline archivistique. Monsieur Minotto partage ensuite quelques anecdotes issues de ses années en tant que directeur de la DGDA afin d’illustrer l’importance des relations de cette dernière avec les autres entités de l’Université de Montréal. Il termine en soulignant différentes réalisations de l’équipe de la DGDA au cours de sa direction et confirme, en conclusion, la nécessité de préserver « la mémoire utile » et ce, peu importe le support et les évolutions technologiques.

« Chevauchements » territoriaux
Authors: Vincent Sylvie 
Published: July 2017

Il est souvent question, dans les documents gouvernementaux, dans les dossiers juridiques et dans les médias, de « chevauchements » entre les territoires des Premières Nations et particulièrement, au Québec, entre les territoires des Algonquiens vivant au nord du Saint-Laurent : Cris, Naskapis, Innus, Atikamekw, Algonquins. À la lumière de ce qu’en ont dit les observateurs depuis le xviie siècle, cet article explore la notion de frontière, tant entre les territoires des nations algonquiennes qu’entre ceux des bandes et/ou communautés et des familles de ces différentes nations. Ces frontières ont-elles existé? Si oui, de quelle nature étaient-elles et comment s’est construite la notion de « chevauchement » qui perturbe aujourd’hui les relations entre les nations algonquiennes et entre les membres de chacune d’elles ? Ce texte s’inscrit dans la réflexion menée, à l’intérieur du programme « Peuples autochtones et gouvernance », par Étienne Le Roy, Jacques Leroux et Sylvie Vincent sur les représentations d’espace et les droits territoriaux.
Sonographic evaluation of the immediate effects of eccentric heel drop exercise on Achilles tendon and gastrocnemius muscle stiffness using shear wave elastography
Authors: Leung Wilson K.C. , Chu KL , Lai Christopher 
Published: July 2017

BackgroundMechanical loading is crucial for muscle and tendon tissue remodeling. Eccentric heel drop exercise has been proven to be effective in the management of Achilles tendinopathy, yet its induced change in the mechanical property (i.e., stiffness) of the Achilles tendon (AT), medial and lateral gastrocnemius muscles (MG and LG) was unknown. Given that shear wave elastography has emerged as a powerful tool in assessing soft tissue stiffness with promising intra- and inter-operator reliability, the objective of this study was hence to characterize the stiffness of the AT, MG and LG in response to an acute bout of eccentric heel drop exercise.MethodsForty-five healthy young adults (36 males and nine females) performed 10 sets of 15-repetition heel drop exercise on their dominant leg with fully-extended knee, during which the AT and gastrocnemius muscles, but not soleus, were highly stretched. Before and immediately after the heel drop exercise, elastic moduli of the AT, MG and LG were measured by shear wave elastography.ResultsAfter the heel drop exercise, the stiffness of AT increased significantly by 41.8 + 33.5% (P < 0.001), whereas the increases in the MG and LG stiffness were found to be more drastic by 75 + 47.7% (P < 0.001) and 71.7 + 51.8% (P < 0.001), respectively. Regarding the AT, MG and LG stiffness measurements, the inter-operator reliability was 0.940, 0.987 and 0.986, and the intra-operator reliability was 0.916 to 0.978, 0.801 to 0.961 and 0.889 to 0.985, respectively.DiscussionThe gastrocnemius muscles were shown to bear larger mechanical loads than the AT during an acute bout of eccentric heel drop exercise. The findings from this pilot study shed some light on how and to what extent the AT and gastrocnemius muscles mechanically responds to an isolated set of heel drop exercise. Taken together, appropriate eccentric load might potentially benefit mechanical adaptations of the AT and gastrocnemius muscles in the rehabilitation of patients with Achilles tendinopathy.

Published: July 2017

This paper is the first public report thatStreptomyces flavogriseuscan produce both actinomycin D and holomycin. The actinomycete strain NJ-4 isolated from the soil of Nanjing Agricultural University was identified asS. flavogriseus. ThisS. flavogriseusstrain was found for the first time to produce two antimicrobial compounds that were identified as actinomycin D and holomycin. GS medium, CS medium and GSS medium were used for the production experiments. All three media supported the production of actinomycin D, while holomycin was detected only in GS medium and was undetectable by HPLC in the CS and GSS media. The antimicrobial activity againstB. pumilus,S. aureus,Escherichia coli,F. moniliforme,F. graminearumandA. nigerwas tested using the agar well diffusion method. Actinomycin D exhibited strong antagonistic activities against all the indicator strains. Holomycin exhibited strong antagonistic activities againstB. pumilus,S. aureusandE. coliand had antifungal activity againstF. moniliformeandF. graminearumbut had no antifungal activity againstA. niger. The cell viability was determined using an MTT assay. Holomycin exhibited cytotoxic activity against A549 lung cancer cells, BGC823 gastric cancer cells and HepG2 hepatocellular carcinoma cells. The yield of actinomycin D fromS. flavogriseusNJ-4 was 960 mg/l.S. flavogriseusNJ-4 exhibits a distinct capability and has the industrial potential to produce considerable yields of actinomycin D under unoptimized conditions.
Carbon storage in the mid‐depth Atlantic during millennial‐scale climate events
Authors: Lacerra Matthew , Lund David , Yu Jimin , Schmittner Andreas 
Published: July 2017

AbstractCarbon isotope minima were a ubiquitous feature of the mid‐depth Atlantic during Heinrich Stadial 1 (HS1, 14.5–17.5 kyr BP) and the Younger Dryas (YD, 11.5–12.9 kyr BP), yet their cause remains unclear. Recent evidence indicates that North Atlantic processes triggered the δ13C anomalies, with weakening of the Atlantic Meridional Overturning Circulation (AMOC) being the most likely driver. Model simulations suggest that slowing of the AMOC increases the residence time of mid‐depth waters in the Atlantic, resulting in the accumulation of respired carbon. Here we assess ΣCO2 variability in the South Atlantic using benthic foraminiferal B/Ca, a proxy for [CO32−]. Using replicated high‐resolution B/Ca records from ~2 km water depth on the Brazil Margin, we show that [CO32−] decreased during HS1 and the YD, synchronous with apparent weakening of the AMOC. The [CO32−] response is smaller than in the tropical North Atlantic during HS1, indicating there was a north–south gradient in the [CO32−] signal similar to that for δ13C. The implied variability in ΣCO2 is consistent with model results, suggesting that carbon is temporarily sequestered in the mid‐depth Atlantic during millennial‐scale stadial events. Using a carbon isotope mass balance, we estimate that approximately 75% of the HS1 δ13C signal at the Brazil Margin was driven by accumulation of remineralized carbon, highlighting the nonconservative behavior of δ13C during the last deglaciation.

AbstractWe present the first meridional transects of atmospheric O2 and CO2 over the Atlantic Ocean. We combine these measurements into the tracer atmospheric potential oxygen (APO), which is a measure of the oceanic contribution to atmospheric O2 variations. Our new in situ measurement system, deployed on board a commercial container ship during 2015, performs as well as or better than existing similar measurement systems. The data show small short‐term variability (hours to days), a step‐change corresponding to the position of the Intertropical Convergence Zone (ITCZ), and seasonal cycles that vary with latitude. In contrast to data from the Pacific Ocean and to previous modeling studies, our Atlantic Ocean APO data show no significant bulge in the tropics. This difference cannot be accounted for by interannual variability in the position of the ITCZ or the Atlantic Meridional Mode Index and appears to be a persistent feature of the Atlantic Ocean system. Modeled APO using the TM3 atmospheric transport model does exhibit a significant bulge over the Atlantic and overestimates the interhemispheric gradient in APO over the Atlantic Ocean. These results indicate that either there are inaccuracies in the oceanic flux data products in the equatorial Atlantic Ocean region, or that there are atmospheric transport inaccuracies in the model, or a combination of both. Our shipboard O2 and CO2 measurements are ongoing and will reveal the long‐term nature of equatorial APO outgassing over the Atlantic as more data become available.
High‐nitrogen fixation rates in the particulate and dissolved pools in the Western Tropical Pacific (Solomon and Bismarck Seas)

Published: July 2017

AbstractDinitrogen (N2) fixation rates were investigated in the euphotic layer of the Bismarck and Solomon Seas using 15N2 incubation assays taking into account both the particulate and the dissolved pools. Average depth‐integrated particulate N2 fixation rates were 203 (range 43–399) and 1396 (range 176–3132) μmol N m−2 d−1 in the Bismarck and Solomon Seas, respectively. In both seas, N2 fixation measured in the dissolved pool was similar to particulate N2 fixation, highlighting the potentially substantial underestimation of N2 fixation in oceanic budgets when only particulate N2 fixation is considered. Among the diazotroph phylotypes targeted using quantitative polymerase chain reaction amplification of nifH genes, Trichodesmium was the most abundant. Regression analyses suggest that it accounted for the major proportion of N2 fixation. However, unicellular cyanobacterial and non‐cyanobacterial diazotrophs were also occasionally abundant. This study reports high pelagic N2 fixation rates and confirms that the Western Tropical South Pacific is a hot spot for marine N2 fixation.
