description: Pour favoriser l’intégration sociale de tous les élèves, j’ai imaginé proposer une intervention qui servirait à interroger et à construire l’environnement de la classe dans la visée d’une école inclusive. Afin d’élaborer la mise en place d'une petite formation spécifique, je me suis inspirée d'un programme américain, le PATHS (Promoting Alternative Thinking Strategies). Dans une première partie de ce programme, des activités sont proposées pour développer l’esprit critique et s’interroger sur des éléments de la vie en classe. Dans une seconde partie, les auteurs ont accordé une place importante au développement des connaissances liées aux émotions. Mes premières lectures m’ont rapidement amenée à constater l’importance du travail sur les émotions dans les relations sociales. Une intervention bi-hebdomadaire a été réalisée avec des élèves de 5 à 6 ans et a permis de développer leurs capacités à « identifier », « différencier » et « verbaliser » les émotions. Durant mon intervention, j’ai présenté de nombreuses émotions. Les caractéristiques de chacune ont été observées, notamment grâce à des dessins sur les expressions faciales. Avec les élèves, nous avons discuté de l’environnement qui provoque les émotions et aussi des comportements qui peuvent être acceptables ou non. Des mesures ont été effectuées sur les émotions de base : « Joie, tristesse, colère et peur » et sur les émotions plus complexes : « Surprise, embarras et fierté ». Des enregistrements ont permis de documenter la participation des élèves afin de me permettre de visualiser leur intérêt pour certains sujets et de vérifier dans quelle mesure ils ont été à la portée de ces derniers. Les émotions ont été placées au centre de ce travail de recherche afin de me permettre de mieux appréhender tout ce qui concerne leur apprentissage et me permettre d’améliorer aussi mon intervention auprès d’élèves atteints de troubles dans les habiletés sociales.

description: Travaillant dans une classe de développement primaire, j’ai été confrontée à des problèmes de violences entre mes élèves : ils se disputaient, s’insultaient, en venaient parfois aux mains. C’est pourquoi, à la rentrée 2015, j’ai décidé de mettre en place dans ma classe plusieurs espaces de parole, outils de la pédagogie institutionnelle, notamment le conseil de classe. Je me suis intéressée aux concepts de violence et d’agressivité, aux éléments pouvant influencer le climat de classe ainsi qu’à l’histoire de la pédagogie institutionnelle et des outils qu’elle propose. Mon but, à travers cette recherche, était de comprendre comment les espaces de parole pouvaient influencer le climat de la classe. Pour ce faire, j’ai mesuré le climat grâce à une échelle standardisée que j’ai adaptée au niveau de compréhension de mes élèves. Les items du questionnaire étaient divisés en plusieurs catégories, basées sur différents éléments pouvant influencer la perception du climat de classe. Ce questionnaire a été passé une première fois en septembre et une seconde fois en janvier. Parallèlement, j’ai tenu un journal de bord où j’ai consigné mon vécu de cette expérience, les sujets abordés lors des conseils de classe etc. Lors de la deuxième passation, j’ai malheureusement constaté que la perception qu’avaient mes élèves du climat de classe s’était dégradée, contrairement à mes espérances et malgré le fait que, moi-même, je le ressente comme étant plus agréable. J’ai cherché des pistes d’explication dans la temporalité de la recherche : en mesurant le climat de classe quelques jours seulement après la rentrée, les premières réponses des élèves reflétaient une réalité différente de la vie ordinaire à l’école. Par ailleurs, j’ai fait l’hypothèse que les enfants osaient davantage s’exprimer en janvier, grâce à tout ce qui avait été mis en place durant les mois précédents, notamment lors du conseil. Cette recherche a été pour moi l’occasion d’approfondir mes connaissances des espaces de parole et d’expérimenter la mise en place de ces outils. De plus, j’ai pu mener une réflexion professionnelle sur l’influence de ces dispositifs sur les élèves.

description: Cool ($T\sim10^4$~K) gas is commonly observed around $z>2$ quasars as traced by extended Ly$α$ emission. These large-scale nebulae are usually studied using circularly averaged surface brightness profiles, which suppress information on morphological differences. Here, we revisit the Ly$α$ nebulae around 78 $z\sim2-3$ quasars to obtain a novel estimate of their area and asymmetry using a common redshift-corrected surface-brightness threshold. We find a luminosity-area relation of the form ${{\rm log}(L_{\rm Lyα}^{\rm Neb})=a_1 log({\rm Area^{Neb})+a_0}}$. Most nebulae are symmetric and bright, the most lopsided ones being the faintest and the less extended. The Enormous Lyman-Alpha Nebulae, asymmetric due to the presence of active companions, are the exceptions to this trend. By using simulations able to reproduce $z\sim6$ quasar's nebulae, we show that the observed relation should not vary with redshift. Finally, we discuss possible mechanisms that drive the relation and future work needed to constrain them.

description: Background: Sociosexuality—attitudes, behaviors, and desires related to casual sex—partly predicts drinking behavior in both men and women because drinking is thought to facilitate interactions that lead to casual sex. It follows that sociosexuality would predict drinking intake (e.g., quantity consumed)—but perhaps not drinking consequences (e.g., blacking out)—on the premise that drinking large quantities with high frequency (but not to such high degrees/levels of intoxication that negative consequences occur) would facilitate casual sex. Objectives: This set of studies evaluated whether baseline measures of sociosexuality predict drinking intake (i.e., frequency, quantity, and binge drinking) but not experiencing blacking out at follow-up in two samples (Study 1, N = 172; Study 2, N = 1,038) of college-aged men. Results: As predicted, men’s sociosexuality prospectively predicted drinking frequency, quantity, and binge drinking. Contrary to our predictions, men’s sociosexuality also predicted blacking out. Conclusions: College men’s drinking interventions should be tailored to high-risk groups and consider individual differences like sociosexuality.
Java Modular Extension for Operator Overloading

Subjects: subject: Programming Languages (cs.PL)
subject: FOS: Computer and information sciences

description: The paper introduces a modular extension (plugin) for Java language compilers and Integrated Development Environments (IDE) which adds operator overloading feature to Java language while preserving backward compatibility. The extension use the idea of library-based language extensibility similar to SugarJ. But unlike most language extensions, it works directly inside the compiler and does not have any external preprocessors. This gives much faster compilation, better language compatibility and support of native developer tools (IDE, build tools). The extension plugs into javac and Eclipse Java compilers as well as in all tools whose use the compilers such as IDEs (Netbeans, Eclipse, IntelliJ IDEA), build tools (ant, maven, gradle), etc. No compiler, IDE, build tools modification needed. Just add a jar library to classpath and/or install a plugin to your IDE. The paper also discuss on how to build such Java compiler extensions. The extension source code is open on http://amelentev.github.io/java-oo/

An Integration of Integrated Information Theory with Fundamental Physics

Subjects: subject: Other Quantitative Biology (q-bio.OT)

description: To truly eliminate Cartesian ghosts from the science of consciousness, we must describe consciousness as an aspect of the physical. Integrated Information Theory states that consciousness arises from intrinsic information generated by dynamical systems; however existing formulations of this theory are not applicable to standard models of fundamental physical entities. Modern physics has shown that fields are fundamental entities, and in particular that the electromagnetic field is fundamental. Here I hypothesize that consciousness arises from information intrinsic to fundamental fields. This hypothesis unites fundamental physics with what we know empirically about the neuroscience underlying consciousness, and it bypasses the need to consider quantum effects.

description: We study the one-parameter family of Fredholm determinants $\det(I-ρ^2\mathcal{K}_{n,x})$, $ρ\in\mathbb{R}$, where $\mathcal{K}_{n,x}$ stands for the integral operator acting on $L^2(x,+\infty)$ with the higher order Airy kernel. This family of determinants represents a new universal class of distributions which is a higher order analogue of the classical Tracy-Widom distribution. Each of the determinants admits an integral representation in terms of a special real solution to the $n$-th member of the Painlevé II hierarchy. Using the Riemann-Hilbert approach, we establish asymptotics of the determinants and the associated higher order Painlevé II transcendents as $x\to -\infty$ for $0<|ρ|<1$ and $|ρ|>1$, respectively. In the case of $0<|ρ|<1$, we are able to calculate the constant term in the asymptotic expansion of the determinants, while for $|ρ|>1$, the relevant asymptotics exhibit singular behaviors. Applications of our results are also discussed, which particularly include asymptotic statistical properties of the counting function for the random point process defined by the higher order Airy kernel.

Voilà pourquoi nous nous sommes posé la question suivante : « Les élèves de 3e HarmoS qui bénéficient de l’enseignement d’une liste de mots de vocabulaire dans plusieurs disciplines performent-ils mieux que ceux qui ne les travaillentqu’en français ? » Pour parvenir à répondre à cette interrogation, nous mettons en place une ingénieriedidactique. Nous procédons donc à un pré-test afin d’évaluer l’investissement des mots que nous souhaitons travailler dans le vocabulaire des élèves. Ensuite, nous élaborons notre séquence pluridisciplinaire basée sur une liste de mots de vocabulaire prédéfinie dans deux classes « test » et nous fournissons cette même liste dans deux classes « témoin », sans donner plus d’indications à l’enseignante pour les transmettre aux élèves. Puis, nous procédons à un post-test qui nous permet de voir l’évolution de l’investissement de ces mots de vocabulaire par les élèves.

description: The triple phase transitions or simultaneous transitions of three different phases, namely topological, parity-time (PT) symmetry breaking, and metal-insulator transitions, are observed in an extension of PT symmetric non-Hermitian Aubry-André-Harper model. In this model, besides non-Hermitian complex quasi-periodic onsite potential, non-Hermiticity is also included in the nearest-neighbor hopping terms. Moreover, the nearest-neighbor hopping terms is also quasi-periodic. The presence of two non-Hermitian parameters, one from the onsite potential and another one from the hopping part, ensures PT symmetry transition in the system. In addition, tuning these two non-Hermitian parameters, we identify a parameters regime, where we observe the triple phase transition. Following some recent studies, an electrical circuit based experimental realization of this model is also discussed.

description: The intricate machinery of perturbative quantum field theory has largely been devoted to the 'dynamical' side of the theory: simple states are evolved in complicated ways. This article begins to address this lopsided treatment. Although it is rarely possible to solve for the eigenstates of an interacting theory exactly, a general state and its evolution can nonetheless be constructed perturbatively in terms of the propagators and structures defined with respect to the free theory. The detailed form of the initial state in this picture is fixed by imposing suitable `renormalization conditions' on the Green's functions. This technique is illustrated with an example drawn from inflation, where the presence of nonrenormalizable operators and where an expansion that naturally couples early times with short distances make the ability to start the theory at a finite initial time especially desirable.

description: Steel-reinforced concrete-filled steel tubular (SR-CFST) columns may be an alternative to improve the fire resistance of concrete-filled steel tubular (CFST) columns, which is limited by the direct exposure of the outer steel tube to the heat source. In SR-CFST sections an open steel profile is embedded within the concrete infill of the CFST section. In a fire situation, this form of construction enhances the performance of the section since the inner steel profile is thermally protected by the surrounding concrete, thus delaying its degradation at high temperatures. In this experimental program, six SR-CFST specimens are tested. First, the specimens are uniformly exposed to high temperatures inside an electric furnace; then the postfire resistance of the columns subject to increasing axial load is tested in a vertical frame. The SR-CFST specimens are grouped into two series comprising circular and square geometries respectively and, for the sake of comparison, the selected circular and square steel tubes utilised the same cross-sectional area of steel. The experimental results show the high ductility of the SR-CFST stub columns after heating, with the circular specimens reaching higher peak loads than the square columns. For each series, the peak load at post-fire increases as the size of the embedded steel profile does. RSI values are similar for both circular and square SR-CFST columns. Data indicate that, for circular columns confinement is still active in the post-fire situation, but the influence of the size of the embedded steel profile is not notable in the RSI.

description: A possible polar-ring debris disc, the dynamics of which can be described by the outer hierarchical restricted three-body problem, has been detected in 99 Herculis. An empirical formula on the minimum radius beyond which test particles in polar orbits can keep stable within ${10^7}$ binary periods is provided through the numerical fitting, applying to the binary eccentricity $e_{1} \in \left[ {0,0.8} \right)$ and the mass ratio of binary $ λ\in \left[ {0.1,1} \right]$, where $ λ= m_0/m_1$ (${m_0}$ and ${m_1}$ represent the masses of the two binary stars). The polar planetary disc has the lowerest statistical accretion efficiency and moderate impact frequency of collisions among planetesimals (with a radius of 1-10km) compared to that in the circumbinary coplanar disc and the standard disc around the single host star. Colliding timescales in the circumbinary disk (both polar and coplanar configuration) are longer than $10^7$ yr exceeding the dissipation timescales of the gas disc. The stochastic simulations show that successive collisions cannot make planetesimal grow up which may explain the formation of the debris disc observed in 99 Herculis.

description: Slow dynamical changes in magnetic-field strength and invariance of the particles' magnetic moments generate ubiquitous pressure anisotropies in weakly collisional, magnetized astrophysical plasmas. This renders them unstable to fast, small-scale mirror and firehose instabilities, which are capable of exerting feedback on the macroscale dynamics of the system. By way of a new asymptotic theory of the early nonlinear evolution of the mirror instability in a plasma subject to slow shearing or compression, we show that the instability does not saturate quasilinearly at a steady, low-amplitude level. Instead, the trapping of particles in small-scale mirrors leads to nonlinear secular growth of magnetic perturbations, $δB/B \propto t^{2/3}$. Our theory explains recent collisionless simulation results, provides a prediction of the mirror evolution in weakly collisional plasmas and establishes a foundation for a theory of nonlinear mirror dynamics with trapping, valid up to $δB/B =O(1)$.

description: En tant que futures enseignantes, nous avons souvent entendu parler d’inclusion scolaire comme modèle de système scolaire. Hélas, nous constatons que sur le terrain, l’inclusion scolaire est loin d’être opératoire. En effet, un tel changement dans nos institutions impliquerait un grand investissement de la part de tous les professionnels du milieu scolaire, des élèves et de leurs parents. De plus, une telle réforme ne peut se mettre en place seulement si la société qui entoure les écoles est elle aussi inclusive, ce qui est loin d’être le cas. À défaut de pouvoir inclure tous les élèves, certains établissements tentent alors d’intégrer les élèves ayant des besoins éducatifs particuliers. Cette pratique n’étant pas aisée pour tous et n’étant pas mis en oeuvre dans tous les établissements, nous tentons, à travers notre mémoire, de déterminer les raisons qui font obstacles à la mise en place d’une école intégrative à visée inclusive et, plus particulièrement, l’impact des attitudes et des représentations des enseignant-e-s sur la réussite de son implantation. Pour répondre à cette problématique, nous avons orienté notre recherche vers les enseignant-e-s, afin de déterminer leurs représentations quant à l’intégration et à l’inclusion scolaire, ainsi que leurs attitudes, traduites par leurs pratiques effectives dans leurs classes respectives. Pour se faire, nous avons fait passer un questionnaire auprès d’enseignant-e-s de deux établissements scolaires du canton de Vaud. Cette recherche nous a permis de spécifier quelques obstacles à la mise en place d’une école intégrative à visée inclusive et nous a amené à formuler des recommandations pour permettre d’offrir un enseignement accessible à tous les élèves. Nous mettons en évidence que cette ambition n’est avant tout possible que si l’établissement offre les besoins matériels nécessaires et invite les enseignant-e-s à davantage se former pour accueillir des élèves à besoins éducatifs particuliers dans le but d’augmenter leur sentiment de compétence. Il est également nécessaire de privilégier des bonnes collaborations entre les collègues au sein des établissements.

description: In geographic information science and technology, various methods and studies exist to characterize the linearity, rectangularity, convexity, circularity or compactness, sinuosity or tortuosity of a given spatial shape. Although there is much work on ellipticity in image processing, we do not address, in geomatics, the issue of matching to a reference elliptical shape. Regarding this issue, this article is a contribution to the qualification of urban open spaces. It provides an operating algorithm for determining a minimum-area bounding ellipse for any given polygonal shape. It also proposes an implementation of this algorithm in the context of a Geographic Information System and a Jupyter Notebook. As an application, it focuses on two real urban configurations on fields of about 300 isovists. The results from the application of this approach in two urban areas in France show that the ellipse is a better minimum bounding geometry than are circle or rectangles, at least for the half-dozen descriptors studied. The improvement relatively to the minimum bounding rectangle is particularly significant in terms of correlation concerning the orientation (+20%) and drift (+10%).

A pre-explosion effervescent zone for the circumstellar material in SN 2023ixf

description: I present the effervescent zone model to account for the compact dense circumstellar material (CSM) around the progenitor of the core collapse supernova (CCSN) SN 2023ixf. The effervescent zone is composed of bound dense clumps that are lifted by stellar pulsation and envelope convection to distances of tens AUs, and then fall back. The dense clumps provide most of the compact CSM mass and exist alongside the regular (escaping) wind. I crudely estimate that for a compact CSM within ~30 AU that contains ~0.01 Mo, the density of each clump is >3000 times the density of the regular wind at the same radius and that the total volume filling factor of the clumps is several percent. The clumps might cover only a small fraction of the CCSN photosphere in the first days post-explosion, accounting for the lack of strong narrow absorption lines. The long-lived effervescent zone is compatible with no evidence for outbursts in the years prior to SN 2023ixf explosion and the large-amplitude pulsations of its progenitor, and it is an alternative to the CSM scenario of several-years-long high mass loss rate wind.

description: Ce travail poursuit deux objectifs distincts liés au processus d’enseignement-apprentissage. Il s’attache d’un côté à identifier les savoirs et habiletés mobilisés par les enseignants en formation dans leur pratique en classe. D’un autre côté, il a pour but de définir les conditions nécessaires pour que les interventions enseignantes favorisent l’apprentissage des élèves. Afin de répondre à ces deux axes de recherche, nous avons analysé deux périodes d’enseignement données par une enseignante-stagiaire en économie et droit au degré secondaire II. Pour ce faire, nous avons choisi une méthode de transcription des interactions entre enseignante et élèves, consistant dans le report fidèle et par écrit des échanges oraux en classe. A partir des transcriptions établies, nous avons ensuite attribué aux différentes prises de paroles les savoirs et habiletés mobilisés correspondants, d’après les informations présentées dans le cadrage théorique. Il est ressorti de notre analyse que l’enseignante-stagiaire a mobilisé en premier lieu et de manière de plus en plus variée des savoirs académiques liés à sa formation pédagogique, en proportion supérieure aux savoirs disciplinaires. Concernant les habiletés, celles de niveau simple de type «restitution» ou « application» ont été les plus représentées, tant chez l’enseignante que chez les élèves; de manière générale, nous avons par ailleurs observé que la mobilisation des différents types d’habiletés s’opérait de manière relativement symétrique entre les deux parties. Cette constatation fait entrevoir des perspectives de développer chez les élèves des habiletés de niveau complexe, du moment que l’enseignant les sollicite.

description: We report on direct numerical simulations of two-dimensional, horizontally periodic Rayleigh-Bénard convection, focusing on its ability to drive large-scale horizontal flow that is vertically sheared. For the Prandtl numbers ($Pr$) between 1 and 10 simulated here, this large-scale shear can be induced by raising the Rayleigh number ($Ra$) sufficiently, and we explore the resulting convection for $Ra$ up to $10^{10}$. When present in our simulations, the sheared mean flow accounts for a large fraction of the total kinetic energy, and this fraction tends towards unity as $Ra\to\infty$. The shear helps disperse convective structures, and it reduces vertical heat flux; in parameter regimes where one state with large-scale shear and one without are both stable, the Nusselt number of the state with shear is smaller and grows more slowly with $Ra$. When the large-scale shear is present with $Pr\lesssim2$, the convection undergoes strong global oscillations on long timescales, and heat transport occurs in bursts. Nusselt numbers, time-averaged over these bursts, vary non-monotonically with $Ra$ for $Pr=1$. When the shear is present with $Pr\gtrsim3$, the flow does not burst, and convective heat transport is sustained at all times. Nusselt numbers then grow roughly as powers of $Ra$, but the growth rates are slower than any previously reported for Rayleigh-Bénard convection without large-scale shear. We find the Nusselt numbers grow proportionally to $Ra^{0.077}$ when $Pr=3$ and to $Ra^{0.19}$ when $Pr=10$. Analogies with tokamak plasmas are described.

description: Nonreciprocal thermal emission is a cutting-edge technology that enables fundamental control over thermal radiation and has exciting applications in thermal energy harvesting. However, so far one of the foremost challenges is making nonreciprocal emission to operate over a broad wavelength range and for multiple angles. In this work, we solve this outstanding problem by proposing three different types of structures always utilizing only one Weyl semimetal (WSM) thin film combined with one or two additional dielectric or metallic layers and terminated by a metallic substrate. First a tradeoff relationship between the magnitude and bandwidth of the thermal nonreciprocity contrast is established based on the thickness of the WSM film. Then, the bandwidth broadening effect is demonstrated via the insertion of a dielectric spacer layer that can also be fine-tuned by varying its thickness. Finally, further control on the resulting strong nonreciprocal thermal radiation is demonstrated by the addition of a thin metallic layer in the proposed few layer designs. The presented composite structures work for a broad frequency range and multiple emission angles, consisting highly advantageous properties to various nonreciprocal thermal radiation applications. Moreover, the proposed designs do not require any patterning and can be experimentally realized by simple deposition fabrication methods. They are expected to aid in the creation of broadband nonreciprocal thermal emitters that can find applications in new energy harvesting devices.

description: The application of external stress on bacteria is a promising approach to evoke cellular responses in bioprocesses to improve production capacities. A prime example is the production of rhamnolipids, eco-friendly biosurfactants that can be used for diverse products. In this study, gene expression profiles of genes associated with the regulation of rhamnolipid synthesis as well as genes for the synthesis itself are presented to identify important points of regulation during such bio processes.

description: We analyze all the available Atacama Large Millimeter / submillimeter Array archival data of the nearby Type-II Seyfert galaxy NGC 1068, including new 100 GHz data with the angular resolution of 0\farcs05, which was not included in previous continuum spectral analysis. By combining with the literature data based on the Very Large Array, we investigate the broadband radio continuum spectrum of the central $\lesssim7$ pc region of NGC 1068. We found that the flux density is between $\approx$10-20 mJy at 5-700 GHz. Due to the inability of the model in previous studies to account for the newly added 100 GHz data point, we proceeded to update the models and make the necessary adjustments to the parameters. One possible interpretation of this broadband radio spectrum is a combination of emission from the jet base, the dusty torus, and the compact X-raying corona with the magnetic field strength of $\approx20$ G on scales of $\approx30$ Schwarzschild radii from the central black hole. In order to firmly identify the compact corona by omitting any other possible extended components (e.g., free-free emission from ionized gas around), high-resolution/sensitivity observations achieved by next-generation interferometers will be necessary.

description: Cette étude cherche à comprendre l’évolution de certains aspects de la sévérité dans l’évaluation en fonction de l’expérience des enseignants. La baisse des moyennes intervenant avec l’augmentation de l’expérience (remarquée dans une étude précédente) est-elle due à une augmentation du niveau taxonomique (Bloom, 1956 ; Anderson et Kratwohl, 2001) des connaissances testées par les enseignants plus expérimentés ? Est-il possible d’identifier d’autres causes ? Les résultats montrent que les enseignants peu expérimentés ont une bonne perception du niveau de difficulté des questions et ont une bonne maitrise de l’analyse d’objets en termes de taxonomie. Ils ont aussi plus d’ambitions de tester des connaissances de niveaux taxonomiques élevés. Certains enseignants expérimentés ont abandonné leurs ambitions d’évaluer des connaissances de haut niveau taxonomique, notamment en raison de la difficulté que cela représente à la correction des épreuves et à la justification auprès des parents. Un modèle explicatif basé sur la protection des enseignants est développé.

description: The purpose of this research is to analyse the dimensions of impersonalization, verbal, sexual and visual aggression in the field of cyber aggression in young people (CAY). In addition to verbal, visual cyber victimization, online exclusion or impersonation in cyber victimization in young people (CVY). The aim of the study was to find out sociodemographic factors and habits involved in cyber aggression and cyber victimization in young people in school aged 14-17 years. The research method was a quasi-experimental descriptive, correlational and predictive study based on a quantitative method. Data were obtained in 2022 through two validated questionnaires, one to measure CAY and the other CVY. A total of 472 young people participated in the sample, of whom 199 were boys and 273 girls, all of them from the autonomous city of Ceuta (Spain) aged between 14 and 17. The most relevant results of the study showed low predictive levels in relation to CVY dimensions, in relation to immigration background, number of siblings and grade repetition, and in relation to CAY in terms of grade repetition. These results, together with the discussion of the study, can contribute data to the educational and psychological field to implement intervention and prevention plans in relation to inappropriate use of the Internet by young people.

description: We examine spatial variations of the C$^0$/CO abundance ratio ($X_{\mathrm{C/CO}}$) in the vicinity of the $γ$-ray supernova remnant W51C, based on [CI] ($^3P_1$-$^3P_0$), $^{12}$CO(1-0), and $^{13}$CO(1-0) observations with the ASTE and Nobeyama 45-m telescopes. We find that $X_{\mathrm{C/CO}}$ varies in a range of 0.02-0.16 (0.05 in median) inside the molecular clouds of $A_V>$100 mag, where photodissociation of CO by the interstellar UV is negligible. Furthermore, $X_{\mathrm{C/CO}}$ is locally enhanced up to by a factor of four near the W51C center, depending on the projected distance from the W51C center. In high-$A_V$ molecular clouds, $X_{\mathrm{C/CO}}$ is determined by the ratio of the cosmic-ray (CR) ionization rate to the H$_2$ density, and we find no clear spatial variation of the H$_2$ density against the projected distance. Hence, the high CR ionization rate may locally enhance $X_{\mathrm{C/CO}}$ near the W51C center. We also find that the observed spatial extent of the enhanced $X_{\mathrm{C/CO}}$ ($\sim$17 pc) is consistent with the diffusion distance of CRs with the energy of 100 MeV. The fact suggests that the low-energy CRs accelerated in W51C enhance $X_{\mathrm{C/CO}}$. The CR ionization rate at the $X_{\mathrm{C/CO}}$-enhanced cloud is estimated to be 3$\times$10$^{-16}$ s$^{-1}$ on the basis of time-dependent PDR simulations of $X_{\mathrm{C/CO}}$, the value of which is 30 times higher than that in the standard Galactic environment. These results demonstrate that [CI] is a powerful probe to investigate the interaction between CRs and the interstellar medium for a wide area in the vicinity of supernova remnants.

description: We present a deep Suzaku observation of H1821+643, an extremely rare example of a powerful quasar hosted by the central massive galaxy of a rich cooling-core cluster of galaxies. Informed by previous Chandra studies of the cluster, we achieve a spectral separation of emission from the active galactic nucleus (AGN) and the intracluster medium (ICM). With a high degree of confidence, we identify the signatures of X-ray reflection/reprocessing by cold and slowly moving material in the AGN's immediate environment. The iron abundance of this matter is found to be significantly sub-solar (Z~0.4Zsun), an unusual finding for powerful AGN but in line with the idea that this quasar is feeding from the ICM via a Compton-induced cooling flow. We also find a subtle soft excess that can be described phenomenologically (with an additional black body component) or as ionized X-ray reflection from the inner regions of a high inclination (i=57 degrees) accretion disk around a spinning (a>0.4) black hole. We describe how the ionization state of the accretion disk can be used to constrain the Eddington fraction of the source. Applying these arguments to our spectrum implies an Eddington fraction of 0.25-0.5, with an associated black hole mass of 3-6x10^9Msun.
