description: L’aspect émotionnel est une des dimensions essentielles à prendre en compte particulièrement chez les élèves du premier cycle car ceux-ci entament de nouvelles expériences au sein de l’école. Ces dernières suscitent de nombreuses émotions qu’ils n’ont peut-être pas ressenties ou explicitées auparavant. C’est pourquoi, notre intérêt s’est porté sur une situation qui peut engendrer des émotions. Notre choix s’est dirigé sur la punition collective car nous avons pu observer cette pratique lors de certains de nos stages ainsi que les vives émotions qu’elle suscite chez des élèves. Perron et Gosselin (2007) à la suite de Harris (1986) démontrent que les enfants plus âgés ont un raisonnement plus riche et distinguent les émotions réelles des émotions apparentes. Piaget (1932) mentionne que les enfants âgés entre 6 et 7 ans sont favorables à la punition collective, contrairement aux enfants âgés de 9 à 11 ans. Charles (1998) relève que l’attitude de l’enseignant a des conséquences sur le comportement des élèves. Notre étude vise donc à comparer le point de vue d’élèves de 1ère HarmoS et de 3ème HarmoS relativement à la richesse du vocabulaire lié aux émotions, au consentement de la punition collective ainsi qu’à la répétition des modes d’enseignement de leur enseignante. Nos résultats montrent des différences entre les élèves selon le degré suivi. Par exemple, il existe des différences entre les élèves de 1H et de 3H au niveau du vocabulaire lié aux émotions. Par contre, les élèves de 1H comme de 3H auraient recours à la punition collective et des élèves de 1H comme de 3H se réfèrent au mode de fonctionnement de leur enseignante. Nos résultats montrent que la richesse du vocabulaire lié aux émotions évolue au fil du temps et que notre enseignement a un impact sur nos élèves. En effet, nos entretiens nous ont permis de constater que ces derniers adhèrent aux méthodes de leur enseignante, par exemple: coin silence ; disperser les élèves dans d’autres classes. Notre recherche nous a donc permis de cerner l’importance de notre mode d’enseignement aux travers des exemples cités.

description: À tout âge et de tout temps, les êtres humains interrogent le monde qui les entoure afin d’essayer de trouver des réponses et un sens à leur existence. L’acte de philosopher n’est donc pas nouveau et peut être accessible à chacun. Pratiquer la philosophie avec des enfants, c’est possible. Cette pratique ne consiste pas à enseigner cette discipline complexe aux élèves mais plutôt à leur permettre de s’exprimer sur des thématiques proches de leur vécu personnel, à partir d’une question qui leur est collectivement soumise. La philosophie pour enfants est encore peu connue et peu pratiquée dans le contexte scolaire. Pourtant, elle semble permettre aux élèves de développer de nombreuses compétences primordiales en société. Dans le cadre de notre mémoire professionnel nous avons mis en place des discussions à visée philosophique, abrégées D.V.P ., ce qui a permis d’offrir aux élèves un espace de parole dans lequel ils pouvaient s’exprimer librement. L’enseignant, par sa position de retrait, a laissé un maximum de place aux élèves. Le but de notre recherche était de pouvoir observer si la pratique de D.V.P. permet effectivement aux enfants de développer une capacité d’expression de leurs opinions personnelles ou non. Pour cela, nous avons mis en place dans deux classes de cycle II des D.V.P. ayant pour support des albums de littérature de jeunesse qui permettaient d’avoir une réflexion sur un thème soulevé par l’ouvrage. Cette démarche a aussi permis de faire entrer la littérature de jeunesse dans la classe, même si nous avons sélectionné nos ouvrages moins pour leur qualité littéraire que pour leur contenu. Lors de cette recherche, les élèves ont été très enthousiastes et ont participé, de manière générale, avec entrain aux discussions proposées. Les élèves ont parlé, échangé et partagé lorsqu’ils en ont eu l’occasion et qu’ils se sont sentis concernés. Des moments riches et agréables ont été vécus.

Enhanced dissipation and inviscid damping in the inviscid limit of the Navier-Stokes equations near the 2D Couette flow

description: In this work we study the long time, inviscid limit of the 2D Navier-Stokes equations near the periodic Couette flow, and in particular, we confirm at the nonlinear level the qualitative behavior predicted by Kelvin's 1887 linear analysis. At high Reynolds number Re, we prove that the solution behaves qualitatively like 2D Euler for times t \lesssim Re^(1/3), and in particular exhibits inviscid damping (e.g. the vorticity weakly approaches a shear flow). For times t \gtrsim Re^(1/3), which is sooner than the natural dissipative time scale O(Re), the viscosity becomes dominant and the streamwise dependence of the vorticity is rapidly eliminated by an enhanced dissipation effect. Afterward, the remaining shear flow decays on very long time scales t \gtrsim Re back to the Couette flow. When properly defined, the dissipative length-scale in this setting is L_D \sim Re^(-1/3), larger than the scale L_D \sim Re^(-1/2) predicted in classical Batchelor-Kraichnan 2D turbulence theory. The class of initial data we study is the sum of a sufficiently smooth function and a small (with respect to Re^(-1)) $L^2$ function.
An Early Neolithic enclosure near West Cotton, Raunds
Creators: name: Chapman, Andy
Publisher: name: Archaeology Data Service
Year: 2020

description: Northamptonshire Archaeology, 39, 3-10
description: A major complex of Neolithic and Bronze Age monuments lying along the Nene valley between Raunds and Stanwick, was investigated in the 1980s as part of the Raunds Area Project. An outlying circular enclosure on higher ground to the east of the prehistoric monuments beneath West Cotton deserted medieval village, the Cotton 'Henge', was trial trenched in 1993, but a firm date was not obtained. Recent extensive trial trenching in advance of a proposed extension to the Warth Park industrial and warehouse complex provided a further opportunity to examine this enclosure. A section across the outer ditch produced primary and lower secondary fills containing quantities of mature oak charcoal. Charcoal from the primary fill has provided a radiocarbon date within the early 4th millennium, 3965-3800 Cal BC at 95% confidence. Even allowing for an old wood effect, this indicates that at least the outer enclosure, at 70-75m diameter, most probably dates to the early Neolithic. It lies directly in line with the long mound at West Cotton, with which it was broadly contemporary. More widely, it would also have been broadly contemporary with the known causewayed enclosure at Briar Hill, Northampton and a newly discovered causewayed enclosure east of Wellingborough, both of which also lie on the slopes of the Nene valley. The smaller inner enclosure, which may have enclosed a mound, as well the flint scatter across the surrounding slopes, probably date to the late Neolithic to early Bronze Age, so that, like the rest of the Raunds monument complex, there was use and reuse throughout the Neolithic and early Bronze Age.
Prospects for Characterizing Host Stars of the Planetary System Detections Predicted for the Korean Microlensing Telescope Network

description: I investigate the possibility of constraining the flux of the lens (i.e., host star) for the types of planetary systems the Korean Microlensing Telescope Network is predicted to find. I examine the potential to obtain lens flux measurements by 1) imaging a lens once it is spatially resolved from the source, 2) measuring the elongation of the point spread function of the microlensing target (lens+source) when the lens and source are still unresolved, and 3) taking prompt follow-up photometry. In each case I simulate observing programs for a representative example of current ground-based adaptive optics (AO) facilities (specifically NACO on VLT), future ground-based AO facilities (GMTIFS on GMT), and future space telescopes (NIRCAM on $JWST$). Given the predicted distribution of relative lens-source proper motions, I find that the lens flux could be measured to a precision of $σ_{H_{\ell}} \leq 0.1$ for $\gtrsim$60$\%$ of planet detections $\geq$5 years after each microlensing event, for a simulated observing program using GMT that images resolved lenses. NIRCAM on $JWST$ would be able to carry out equivalently high-precision measurements for $\sim$28$\%$ of events $Δt$ = 10 years after each event by imaging resolved lenses. I also explore the effects various blend components would have on the mass derived from prompt follow-up photometry, including companions to the lens, companions to the source, and unassociated interloping stars. I find that undetected blend stars would cause catastrophic failures (i.e., $>$50$\%$ fractional uncertainty in the inferred lens mass) for $\lesssim$(16$\cdot f_{\rm bin})\%$ of planet detections, where $f_{\rm bin}$ is the binary fraction, with the majority of these failures occurring for host stars with mass $\lesssim$0.3$M_{\odot}$.

description: In this paper we present the distribution of molecular gas in the Milky Way Galactic plane from $l$ = [59.75, 74.75]$^{\circ}$ and $b$ = [${-}$5.25, +5.25]$^{\circ}$, using the MWISP $^{12}$CO/$^{13}$CO/$\rm {C}^{18}{O}$ emission line data. The molecular gas in this region can be mainly attributed to the Local spur, Local arm, Perseus arm, and Outer arm. Statistics of the physical properties of the molecular gas in each arm, such as excitation temperature, optical depth, and column density, are presented. Using the DBSCAN algorithm, we identified 15 extremely distant molecular clouds with kinematic distances of 14.72$-$17.77 kpc and masses of 363$-$520 M$_{\odot}$, which we find could be part of the Outer Scutum-Centaurus (OSC) arm identified by \cite{2011ApJ...734L..24D} and \cite{2015ApJ...798L..27S}. It is also possible that, 12 of these 15 extremely distant molecular clouds constitute an independent structure between the Outer and the OSC arms or a spur. There exist two Gaussian components in the vertical distribution of the molecular gas in the Perseus spiral arm. These two Gaussian components correspond to two giant filaments parallel to the Galactic plane. We find an upward warping of the molecular gas in the Outer spiral arm with a displacement of around 270 pc with respect to the Galactic mid-plane.

Dans le cadre de notre étude, nous nous sommes principalement focalisées sur les préoccupations des enseignants, qu’elles soient d’ordre purement technique, pédagogique ou encore relatives à la gestion de classe. Pour ce faire, nous avons utilisé la théorie de l’action qui offre le cadre théorique nécessaire pour établir un lien direct entre l’acte accompli et la conscience préréflexive de l’enseignant. Ce lien est la manière dont l’enseignant anticipe, se projette et analyse une situation particulière à un instant donné avec et à travers son expérience vécue. Le traitement de la nature de ce lien grâce à l'exploitation des signes hexadiques nous a donné la possibilité d'en faire ressortir les préoccupations des enseignants.

description: Ce mémoire professionnel propose d’examiner l’applicabilité de la méthode KPK dans l’enseignement de la physique au cycle 3. Le KPK « Der Karlsruher PhysikKurs » est un cours d’enseignement de la physique basée sur des principes énergétiques et sur des similitudes présentes entre divers phénomènes en physique ou en chimie. Les objectifs pédagogiques qui ont guidé à la conception de cette approche découlent de sa structure en tant que méthode démonstrative, de sa démarche scientifique, de sa théorisation scientifique, de son niveau formel, de son historicité, de son statut comme analogie-modélisante, de sa place dans l’économie « langagière » et de ses possibles applications dans les diverses branches de la science. Cette recherche a été menée par le biais d’une construction et de l’enseignement de séquences de la physique (en électricté et hydraulique), dans deux niveaux différents du cycle 3. En premier lieu, une première puis une deuxième ont été mises en place afin de récolter des informations sur l’efficacité de cette méthode quant à l’apprentissage des élèves. Ainsi, les données récoltées et les observations réalisées, ont montré toutefois que, la méthode KPK, comme cours d’enseignement, dépend fortement de l’approche didactique entreprise. Ce qui nous a permis d’aboutir à une nouvelle séquence, construite sur une démarche socioconstructive, en cohérence avec le cadre du PER et typée KPK. Dans cette recherche, nous avons essayé de contribuer à éclairer la pratique dans l’acte d’enseigner les sciences au secondaire I, en utilisant la méthode KPK et de montrer ses usages possibles en classe. Ce mémoire s’adresse à toute personne s’intéressant à enseigner les sciences, en utilisant l’outil KPK. La méthode KPK, accompagnée par une démarche socioconstructive, reste industrieuse, par son pouvoir heuristique et son principe de transfert « psychologique », permet de mieux structurer le savoir de l’élève.

description: Northamptonshire Archaeology, 39, 11-36
description: In 2012 an excavation was undertaken in advance of housing development to the south of Banbury Lane, Middleton Cheney, following the discovery of two pits containing Late Neolithic grooved ware pottery during the evaluation. Further definitive evidence of Neolithic activity was not located, but three Early Bronze Age cremation burials lay in the vicinity of the Neolithic features. Two cremation burials were unurned and unaccompanied by grave goods; the third was interred in an inverted collared urn, which also contained a ceramic spoon and a bronze awl. An Early Bronze Age circular post-built structure was located south-east of the cremations. The date of the Neolithic and Bronze Age features has been confirmed by radiocarbon dating. More recent features comprised a Roman field boundary ditch and postholes, remnants of medieval ridge-and-furrow cultivation strips, and a post-medieval inclosure ditch.

description: Fruit d’une passion pour les langues et la littérature mondiale, le présent travail se propose de sensibiliser les élèves du secondaire (9 à 11H) à la poésie sous un angle nouveau. Après avoir rappelé les enjeux de la recherche-action et d’EOLE (éducation et ouverture aux langues à l’école), puis passé en revue la littérature de la didactique du français et/ou de la poésie, nous présentons une séquence qui, partant de l’opaque des langues inconnues, tente d’initier les élèves aux poèmes par l’oeil et par l’oreille. Le premier module s’intéresse à la mise en page (vers, strophes, blancs…) d’oeuvres faisant appel à des systèmes d’écritures différents du nôtre (devanagari, cyrillique, grec, japonais…), pour mener les élèves aux plaisirs des poèmes figurés et des calligrammes par une première production. Le second module est consacré aux sonorités de la poésie, d’abord par l’écoute de textes sans-krit, russe et grec ancien, puis par l’étude des syllabes (pieds), des rimes, des assonances, des allitérations et des onomatopées, avec en ligne de mire l’amélioration du premier texte. Enfin, une large part du présent travail revient sur la mise à l’épreuve de notre séquence dans deux classes de voies générale et prégymnasiale. Des réactions de nos élèves, nous avons tenté de tirer de nouveaux enseignements. Convoquant, sous l’égide des plus grands auteurs (Aristophane, Baudelaire, Apollinaire…), de nombreuses langues mortes ou vives, notre travail entend faire descendre le français du piédes-tal auquel certaines pédagogies le condamnent et emmener la poésie hors des sentiers battus. C’est dire l’importance portée à la perspective historique et comparative, mais aussi au décloi-sonnement des branches, à l’interdisciplinarité, comme à la stimulation de la curiosité des élèves. S’ils dépassent leur peur de l’inconnu, s’ils comprennent les règles strictes pour mieux les enfreindre, et surtout si l’envie les saisit de faire des vers, notre objectif sera atteint.

description: We evaluate non-local thermodynamical equilibrium (non-LTE) line formation for neutral sodium in model atmospheres of the 79 red giants using the model atom that incorporates the best available atomic data. The non-LTE abundances of Na were determined from Na I 6154, 6161 Å for the 38 stars of the thin disk (15 of them the BaII stars), 15 stars of the thick disk, 13 stars of Hercules stream and 13 transition stars which can be identified with neither thin disk nor thick disk. For Na I 6154, 6161 Å non-LTE abundance corrections amount to -0.06 to -0.24 dex depending on stellar parameters. We found no difference in [Na/Fe] abundance between the thick disk and thin disk and the obtained abundances are close to the solar one. We confirmed a weak excess of [Na/Fe] in BaII stars. Stars of the Hercules stream reveal [Na/Fe] abundances close to the solar one. The obtained results can be used to constrain the nucleosynthesis models for Na.

description: With the advent of multilingual models like mBART, mT5, IndicBART etc., summarization in low resource Indian languages is getting a lot of attention now a days. But still the number of datasets is low in number. In this work, we (Team HakunaMatata) study how these multilingual models perform on the datasets which have Indian languages as source and target text while performing summarization. We experimented with IndicBART and mT5 models to perform the experiments and report the ROUGE-1, ROUGE-2, ROUGE-3 and ROUGE-4 scores as a performance metric.

description: Herbig Ae/Be stars lie in the mass range between low and high mass young stars, and therefore offer a unique opportunity to observe any changes in the formation processes that may occur across this boundary. This paper presents medium resolution VLT/X-Shooter spectra of six Herbig Ae/Be stars, drawn from a sample of 91 targets, and high resolution VLT/CRIRES spectra of five Herbig Ae/Be stars, chosen based on the presence of CO first overtone bandhead emission in their spectra. The X-Shooter survey reveals a low detection rate of CO first overtone emission (7 per cent), consisting of objects mainly of spectral type B. A positive correlation is found between the strength of the CO v=2-0 and Br γ emission lines, despite their intrinsic linewidths suggesting a separate kinematic origin. The high resolution CRIRES spectra are modelled, and are well fitted under the assumption that the emission originates from small scale Keplerian discs, interior to the dust sublimation radius, but outside the co-rotation radius of the central stars. In addition, our findings are in very good agreement for the one object where spatially resolved near-infrared interferometric studies have also been performed. These results suggest that the Herbig Ae/Be stars in question are in the process of gaining mass via disc accretion, and that modelling of high spectral resolution spectra is able to provide a reliable probe into the process of stellar accretion in young stars of intermediate to high masses.

description: Hydrogels have attracted extensive attention for their promising applications as flexible sensors. Developing conductive hydrogels with excellent mechanical properties still remains a significant challenge. Herein, double-network (DN) hydrogels composed of poly(vinyl alcohol) (PVA) and poly(ionic liquids) (PILs) are prepared through repetitive freezing/thawing process. The hydrogels are further treated with Fe3+ ions to enhance the mechanical properties due to the complexation between carboxyl groups and Fe3+ ions. The influence of the amount of PILs and concentration of Fe3+ on mechanical properties and conductivity is investigated. The optimal DN hydrogel P(VMCA-AA)1/PVA-Fe3+4 shows excellent mechanical properties, whose tensile strength, elongation at break, and toughness are 2.2 MPa, 350%, and 3.5 MJ m−3, respectively. P(VMCA-AA)1/PVA-Fe3+4 also displays a good conductivity of 1.04 S m−1. Moreover, the hydrogel demonstrates a high sensing sensitivity with a gauge factor (GF) of 3.36, indicating its application potential as a flexible sensor.

SPARC HSBs, and LSBs, the surface density of dark matter haloes, and MOND

description: In this paper, we use SPARC's HSBs, and LSBs galaxies to verify two issues. The first one is related to one claim of \citep{Donato} D09, namely: is the DM surface density (DMsd) a constant universal quantity, equal to $\log{(\rm Σ/M_\odot pc^{-2})}=2.15 \pm 0.2$, or does it depend on the baryon surface density of the system? The second one, is based on a MOND prediction that for HSBs the DMsd is constant, and equal to $\log{(\rm Σ/M_\odot pc^{-2})}=2.14$, while for LSBs the surface density is not constant and takes values that are smaller than for HSBs and D09 prediction \citep{Milgrom2009}. We find that HSBs shows a constant DMsd vs magnitude as in D09, and a constant DMsd vs $Σ_{\rm eff}$ as in MOND prediction, for HSBs with $Σ_{\rm eff}>200 L_\odot/pc^2$, and $Σ_{\rm eff}>300 L_\odot/pc^2$. However, the value of the DMsd is larger, $Σ\simeq 2.61$ (in the case of the DMsd-magnitude with $Σ_{\rm eff}>300 L_\odot/pc^2$), and $Σ\simeq 2.54$ (in the case of the surface DMsd-surface brightness with $Σ_{\rm eff}>200 L_\odot/pc^2$). This value slightly depends on the threshold to determine wheter a galaxy is HSB. In the case of LSBs, for $Σ_{\rm eff}<100 L_\odot/pc^2$, and $Σ_{\rm eff}<25 L_\odot/pc^2$, the surface density vs magnitude, for lower magnitudes, is approximately equal to that predicted by D09, but several galaxies, for magnitude $M>-17$, have smaller values than those predicted by D09. The DMsd vs $Σ_{\rm eff}$ shows a similar behavior in qualitative, but not quantitative, agreement with MOND predictions. In summary, in the case of HSBs both D09 and MOND are in qualitative, but not quantitative, agreement with the data. In the case of LSBs D09 is mainly in disagreement with the data, and MOND only in qualitative agreement with them.

description: This final article in the four-part series focuses on the often neglected yet important role of the public in implementing research in General Practice and Primary Care more broadly. Experience in implementation of findings from research with public engagement in Primary Care has highlighted how partnership working with patients and the public is important in transitioning from ‘what we know’ from the evidence-base to ‘what we do’ in practice. Factors related to Primary Care research that make public engagement important are highlighted e.g. implementing complex interventions, implementing interventions that increase health equity, implementing interventions in countries with different primary healthcare system strengths. Involvement of patients and public can enhance the development of modelling and simulation included in studies on systems modelling for improving health services. We draw on the emerging evidence base to describe public engagement in implementation and offer some guiding principles for engaging with the public in the implementation in General Practice and Primary Care in general. Illustrative case studies are included to support others wishing to offer meaningful engagement in implementing research evidence.

We evaluate Wigner functions for the $ψ(2S)$ meson using both Gaussian and Coulomb wave functions, and investigate the wave function dependence in the $ψ(2S)$ meson production by recombination of charm and anti-charm quarks. The enhanced transverse momentum distribution of $ψ(2S)$ mesons compared to that of $J/ψ$ mesons, originated from wave function distributions of the $ψ(2S)$ and $J/ψ$ meson in momentum space, provides a plausible explanation for the recent measurement of the nuclear modification factor ratio between the $ψ(2S)$ and $J/ψ$ meson.

description: Aims. Fast Radio Bursts are bright radio transients whose origin has not yet explained. The search for a multi-wavelength counterpart of those events can put a tight constrain on the emission mechanism and the progenitor source. Methods. We conducted a multi-wavelength observational campaign on FRB 20180916B between October 2020 and August 2021 during eight activity cycles of the source. Observations were led in the radio band by the SRT both at 336 MHz and 1547 MHz and the uGMRT at 400 MHz. Simultaneous observations have been conducted by the optical telescopes Asiago (Galileo and Copernico), CMO SAI MSU, CAHA 2.2m, RTT-150 and TNG, and X/Gamma-ray detectors on board the AGILE, Insight-HXMT, INTEGRAL and Swift satellites. Results. We present the detection of 14 new bursts detected with the SRT at 336 MHz and seven new bursts with the uGMRT from this source. We provide the deepest prompt upper limits in the optical band fro FRB 20180916B to date. In fact, the TNG/SiFAP2 observation simultaneous to a burst detection by uGMRT gives an upper limit E_optical / E_radio < 1.3 x 10^2. Another burst detected by the SRT at 336 MHz was also co-observed by Insight-HMXT. The non-detection in the X-rays yields an upper limit (1-30 keV band) of E_X-ray / E_radio in the range of (0.9-1.3) x 10^7, depending on which model is considered for the X-ray emission.

description: Northamptonshire Archaeology, 39, 85-100
description: Excavations prior to housing development to the northwest of Crick located probable middle to late Bronze Age activity with the discovery of a possible burnt mound. These are uncommon features in Northamptonshire and this one, with an associated stake- or post-built structure, brings the total to three from recent work in the area. An Iron Age settlement enclosure, built over earlier Iron Age boundary ditches, contained the remains of ring gullies (roundhouses) and ancillary buildings or structures represented by ditches and postholes. The inside of the enclosure was reorganised in the Roman period, with a ditch bisecting the interior and truncating earlier features. A relatively small amount of pottery and animal bone was recovered, but the environmental evidence was good and points to a mixed pastoral/agricultural economy. Pottery shows that the main period of use was early Roman, with no indication of activity beyond c.AD 200. The enclosure ditch gradually silted up, its banks slumped inwards and a later trackway cut through its south-eastern side. A small amount of Anglo-Saxon pottery in later features, including what may have been a quarry pit, shows that there was later activity.
Beyond dimension six in SM Effective Field Theory: a case study in Higgs pair production at NLO QCD

description: We present the NLO (two-loop) QCD corrections to Higgs boson pair production in gluon fusion within Standard Model Effective Theory (SMEFT), including also squared dimension-6 operators and double insertions of operators. The different options to truncate the EFT expansion are contrasted to a non-linear EFT approach (HEFT) and their effects are illustrated by several phenomenological examples.

description: The present work deals with the classical and quantum aspects of the Raychaudhuri equation in the framework of f(T)-gravity theory. In the background of homogeneous and isotropic Friedmann Lemaitre Robertson Walker space time, the Raychaudhuri equation has been formulated and used to examine the focusing theorem and convergence condition for different choices of f(T). Finally in quantum cosmology, the wave function of the universe has been shown to be the energy eigen function of the time independent Schrodinger equation of a particle. Also probability measure on the mini-super space has been examined at zero volume for singularity analysis in the quantum regime. Lastly the Bohmian trajectory for the present quantum system has been explicitly determined for some particular choices.

description: Liposomes are widely used for smart delivery due to their biodegradability and biocompatibility. Recently, liposomes have been developed to respond to dual and multi-stimuli. This development leads to the potential for superior in vitro and in vivo drug delivery in the future. In this study, egg PC liposomes responsive to temperature, oxidation, and NIR irradiation were prepared by modifying the liposomal membranes with poly(hydroxyethyl acrylate-co-ethyl vinyl sulfide) (P(HEA-co-EVS)) and including indocyanine green (ICG) in the liposomes.The copolymer was found to exhibit a lower critical solution temperature (LCST) and it was oxidizable and surface-active.On the TEM photos of the liposomes, multi-lamellar vesicles were found and the size was in accordance with the hydrodynamic diameter. The liposomes released their payload in response to H2O2 concentration possibly because the EVS was oxidized by the oxidizing agent. The liposome exhibited a temperature-responsive release possibly due to the thermal contraction of the copolymer chains.In addition, the release was triggered when a near-infrared(NIR) laser was irradiated to the liposome suspensions. Under NIR irradiation, the photosensitizer (i.e. ICG) can generate heat and reactive oxygen species, which, in turn, would induce the conformational and polarity change of the polymer chains, leading to a release.
A Search For Star Formation in the Smith Cloud

description: Motivated by the idea that a subset of HVCs trace dark matter substructure in the Local Group, we search for signs of star formation in the Smith Cloud, a nearby ~2x10^6 Msun HVC currently falling into the Milky Way. Using GALEX NUV and WISE/2MASS NIR photometry, we apply a series of color and apparent magnitude cuts to isolate candidate O and B stars that are plausibly associated with the Smith Cloud. We find an excess of stars along the line of sight to the cloud, but not at a statistically significant level relative to a control region. The number of stars found in projection on the cloud after removing an estimate of the contamination by the Milky Way implies an average star formation rate surface density of 10^(-4.8 +/- 0.3) Msun yr^(-1) kpc^(-2), assuming the cloud has been forming stars at a constant rate since its first passage through the Milky Way ~70 Myr ago. This value is consistent with the star formation rate expected based on the average gas density of the cloud. We also discuss how the newly discovered star forming galaxy Leo P has very similar properties to the Smith Cloud, but its young stellar population would not have been detected at a statistically significant level using our method. Thus, we cannot yet rule out the idea that the Smith Cloud is really a dwarf galaxy.

description: Observations of low-ionization state (LIS) metal lines provide crucial insights into the interstellar medium of galaxies, yet, disentangling the physical processes responsible for the emerging line profiles is difficult. This work investigates how mock spectra generated using a single galaxy in a radiation-hydrodynamical simulation can help us interpret observations of a real galaxy. We create 22,500 C II and Si II spectra from the virtual galaxy at different times and through multiple lines of sight and compare them with the 45 observations of low-redshift star-forming galaxies from the COS Legacy Spectroscopic SurveY (CLASSY). We find that the mock profiles provide accurate replicates to the observations of 38 galaxies with a broad range of stellar masses ($10^6$ to $10^9$ $M_\odot$) and metallicities (0.02 to 0.55 $Z_\odot$). Additionally, we highlight that aperture losses explain the weakness of the fluorescent emission in several CLASSY spectra and must be accounted for when comparing simulations to observations. Overall, we show that the evolution of a single simulated galaxy can produce a large diversity of spectra whose properties are representative of galaxies of comparable or smaller masses. Building upon these results, we explore the origin of the continuum, residual flux, and fluorescent emission in the simulation. We find that these different spectral features all emerge from distinct regions in the galaxy's ISM, and their characteristics can vary as a function of the viewing angle. While these outcomes challenge simplified interpretations of down-the-barrel spectra, our results indicate that high-resolution simulations provide an optimal framework to interpret these observations.

description: L'absentéisme, peu documenté dans la littérature scientifique, est habituellement présenté comme un prédicteur du décrochage scolaire. Dans une perspective de prévention primaire, se pencher sur le phénomène, à travers un recensement régulier et des évaluations systématiques des pratiques d'absentéisme des élèves, peut constituer le premier jalon vers une prise en charge efficace des jeunes à risque. Dans ce mémoire, deux domaines ont été explorés : la prévalence de l'absentéisme dans un collectif de 802 adolescents ayant fréquenté l'Organisme de Perfectionnement, de Transition et d'Insertion professionnelle (OPTI) durant l'année scolaire 2010-2011, et la faisabilité d'une mesure du risque de décrochage scolaire auprès de 183 élèves actuellement inscrits dans cette structure du post-obligatoire. La prévalence de l'absentéisme s'élève à 17.5%. Nos analyses tendraient à démontrer que les absentéistes ne présentent a priori pas de profil particulier : ce ne sont ni les meilleurs élèves, ni les plus mauvais. En outre, il pourrait exister un effet lié au site de formation. Pour la mesure du décrochage scolaire, nous avons utilisé une version adaptée de l'échelle de Dépistage en Milieu Scolaire (DEMS) de P. Potvin & al. (2003). L'implémentation du dispositif et la récolte de données n'ont posé aucun problème. Les analyses ont mis en évidence un risque modéré, ou un risque élevé de décrochage scolaire, pour respectivement 12% et 8% des adolescents interrogés. Parmi les motifs d’absence les plus souvent évoqués nous trouvons une vraie maladie, puis une baisse de la motivation. Ce dernier est plus fréquemment avancé quand l'adolescent a décroché une place d'apprentissage. Au terme de ce travail, nous proposons la mise en place de mesures régulières de l'absentéisme et du risque de décrochage scolaire, un suivi plus attentif des problèmes de santé des élèves de l'OPTI, et la désignation d'un coordinateur chargé de la gestion de ces phénomènes.
