Self-concept and person perception in children in grades two to four
Creators: name: Patterson, Cynthia Clare
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to explore the development of self-concept and person perception in children in grades two, three and four. The study was designed to investigate three questions: (a) if grade three or four children would have significantly higher frequency and differentiation scores on the 'Who-am I?' and 'friend' description than grade twos; (b) if grade three or four students would show an increase on specified types of abstract content and a decrease in concrete content in answer to the two questions as compared to grade twos; and (c) if a modal shift would occur between the 'egocentric-concrete' and 'nonego-centric-concrete' categories in response to the 'friend' description from grade two to grades three or four. A total of 111 primary children, 25 grade twos, 52 grade threes and 34 grade fours were tested on the WAI and 'friend' questions. The data were analyzed in terms of the three statistical hypotheses. The results showed that grades three or four increased significantly in frequency of response and differentiation to both the WAI and 'friend' descriptions. Main effects for question type were found in six content categories, and for grade in three content categories. Grade by question interactions was found in two content categories. Finally, a modal shift occurred from the 'egocentric-concrete' to 'nonegocentric-concrete' categories from grades two to three. Some limitations of the study and implications for future research follow.

description: The structural and magnetic properties of Y$_{0.9}$Pr$_{0.1}$Fe$_2$D$_{3.5}$ deuteride have been investigated by synchrotron and neutron diffraction, magnetic measurements, and differential scanning calorimetry. Deuterium insertion induces a 23.5 % cell volume increase and a lowering of crystal symmetry compared to the cubic C15 parent compound (Fd-3m SG). The deuteride is monoclinic (P21/c SG) below 330 K and undergoes a first order transition between 330 and 350 K towards a pseudo-cubic structure (R-3m SG) with TO-D = 342(2) K. The compound is ferromagnetic, accompanied by a magnetostrictive effect below TC = 274 K. The analysis of the critical exponents indicates a second order type transition with a deviation from the isotropic 3D Heisenberg model towards the 3D XY model. This implies an easy plane of magnetization in agreement with cell parameter variation showing a planar magnetic orientation. A weak magnetic peak is even observed at the order-disorder transition with a maximum at 343 K. Magnetic entropy variations are characteristic of direct and reverse magnetocaloric effects at TC and TO-D respectively.

title: Giorgio de Chirico's metaphysical art and Schopenhauer's metaphysics: an exploration of the philosophical concept in de Chirico's prose and paintings
Creators: name: Heins, Barbara
Publisher: name: University of Kent
Year: 2021

description: The present thesis starts with an outline of the importance de Chirico attached to philosophy and shows that attitude in relation to the reception by his critics. The second chapter examines the informing principles of Schopenhauer's metaphysics in relation to de Chirico's theoretical writings. Subsequently there is a chapter on the figure of Ariadne, demonstrating how Schopenhauerian principles, mythical conceptions and Nietzschean rhetoric are synthesized in de Chirico's Metaphysical Art in a clear attempt to transfer the philosophical programme onto canvas. Chapter IV looks more closely at the labyrinthine nature of de Chirico's paintings and his novel Hebdomeros in accordance with the Schopenhauer-inspired philosophical background: the setting up of ontological puzzles, and the handling of space and time. There follows a discussion in Chapter V of the presentation of objects and figures in these labyrinthine spaces: their exemption from causality, and objectivisation in the attainment of the metaphysical other. The thesis concludes with an exploration of the artist genius against the background of Schopenhauer.

description: We consider the spectral and dynamical properties of quantum systems of $n$ particles on the lattice $\Z^d$, of arbitrary dimension, with a Hamiltonian which in addition to the kinetic term includes a random potential with iid values at the lattice sites and a finite-range interaction. Two basic parameters of the model are the strength of the disorder and the strength of the interparticle interaction. It is established here that for all $n$ there are regimes of high disorder, and/or weak enough interactions, for which the system exhibits spectral and dynamical localization. The localization is expressed through bounds on the transition amplitudes, which are uniform in time and decay exponentially in the Hausdorff distance in the configuration space. The results are derived through the analysis of fractional moments of the $n$-particle Green function, and related bounds on the eigenfunction correlators.

description: We present novel cosmological constraints based on a joint analysis of our HII galaxies (HIIG) Hubble relation with the full Planck Cosmic Microwave Background anisotropy spectrum and the Baryon Acoustic Oscillations (BAO) probes. The HII galaxies span a large redshift range $(0.088 \le z \le 2.5)$, reaching significantly higher redshifts than available SNIa and hence they probe the cosmic expansion at earlier times. Our independent constraints compare well with those based on the Pantheon compilation of SNIa data, which we also analyse. We find our results to be in agreement with the conformal $Λ$CDM model within 1$σ$. We also use our HIIG data to examine the behaviour of the dark energy equation of state parameter under the CPL parameterisation, $w = w_0+w_a \frac{z}{1+z}$, and find consistent results with those based on SNIa, although the degeneracy in the parameter space as well as the individual parameter uncertainties, when marginalizing one over the other, are quite large.

description: This paper began as an oral presentation delivered at the Pedagogies of Decolonizationand Reconciliation in the Post-Secondary Classroom event sponsored by the CanadianCritical Pedagogy Association and the Congress of the Social Sciences and Humanities,held May 29, 2017 at Ryerson University. It discusses an interdisciplinary approachto breaking through "settler unconsciousness" using a pedagogy deeply influenced byIndigenous concepts of learning as a process of reciprocity and of understanding "self­in-relationship. "y4sa settler educator, I acknowledge and think through the implica­tions of my own positionality for teaching, and assist students with their personalself-location through four frames of analysis. These include decolonizing the historyof Canada; understanding colonialism and anticolonial struggle comparatively andtransnationally; locating oneself in the local context; and locating oneself through fam­ily migration and time. students explore their own relationship to colonialism andthe interrelationship of these frames in an initial personal reflection assignment whichis shared in the classroom, students learn about the global reach of colonialism, buildcommunity among diverse students, and come to recognize the effects of colonialismon the whole person—a crucial strategy since colonialism is a psychological structureof emotions as well as a political, social, legal, and economic set of relationships. A sec­ond pedagogical theme follows from this self-location: acknowledging relationship andrecognizing one's responsibilities. The ethic of relationship and responsibility at thecore of Indigenous worldviews and ethics is also powerfully conveyed to studentsthrough co-teaching. I conclude with some reflections on co-teaching as a powerfulmodel for Indigenous-non-Indigenous relationship and effective teaching about decol­onization, drawing on personal experiences of teaching one-on-one with an Indigenousscholar, and in partnership with an Indigenous organization and support group of res­idential school survivors.

description: We present further development and the first public release of our multimodal nested sampling algorithm, called MultiNest. This Bayesian inference tool calculates the evidence, with an associated error estimate, and produces posterior samples from distributions that may contain multiple modes and pronounced (curving) degeneracies in high dimensions. The developments presented here lead to further substantial improvements in sampling efficiency and robustness, as compared to the original algorithm presented in Feroz & Hobson (2008), which itself significantly outperformed existing MCMC techniques in a wide range of astrophysical inference problems. The accuracy and economy of the MultiNest algorithm is demonstrated by application to two toy problems and to a cosmological inference problem focussing on the extension of the vanilla $Λ$CDM model to include spatial curvature and a varying equation of state for dark energy. The MultiNest software, which is fully parallelized using MPI and includes an interface to CosmoMC, is available at http://www.mrao.cam.ac.uk/software/multinest/. It will also be released as part of the SuperBayeS package, for the analysis of supersymmetric theories of particle physics, at http://www.superbayes.org

The calculated charged multiplicity and the charged particle transverse momentum distribution, pseudorapidity distribution, and extended longitudinal scaling for Au+Au collisions well agree with the corresponding PHOBOS data. Thus the above observables calculated for Pb+Pb collisions would be a reliable prediction.

description: Predicting DNA-protein binding is an important and classic problem in bioinformatics. Convolutional neural networks have outperformed conventional methods in modeling the sequence specificity of DNA-protein binding. However, none of the studies has utilized graph convolutional networks for motif inference. In this work, we propose to use graph convolutional networks for motif inference. We build a sequence k-mer graph for the whole dataset based on k-mer co-occurrence and k-mer sequence relationship and then learn DNA Graph Convolutional Network (DNA-GCN) for the whole dataset. Our DNA-GCN is initialized with a one-hot representation for all nodes, and it then jointly learns the embeddings for both k-mers and sequences, as supervised by the known labels of sequences. We evaluate our model on 50 datasets from ENCODE. DNA-GCN shows its competitive performance compared with the baseline model. Besides, we analyze our model and design several different architectures to help fit different datasets.

description: Particle agglutination assays are widely adapted immunological tests that are based on antigen-antibody interactions. Antibody-coated microscopic particles are mixed with a test sample that potentially contains the target antigen, as a result of which the particles form clusters, with a size that is a function of the antigen concentration and the reaction time. Here, we present a quantitative particle agglutination assay that combines mobile lens-free microscopy and deep learning for rapidly measuring the concentration of a target analyte; as its proof-of-concept, we demonstrate high-sensitivity C-reactive protein (hs-CRP) testing using human serum samples. A dual-channel capillary lateral flow device is designed to host the agglutination reaction using 4 uL of serum sample with a material cost of 1.79 cents per test. A mobile lens-free microscope records time-lapsed inline holograms of the lateral flow device, monitoring the agglutination process over 3 min. These captured holograms are processed, and at each frame the number and area of the particle clusters are automatically extracted and fed into shallow neural networks to predict the CRP concentration. 189 measurements using 88 unique patient serum samples were utilized to train, validate and blindly test our platform, which matched the corresponding ground truth concentrations in the hs-CRP range (0-10 ug/mL) with an R2 value of 0.912. This computational sensing platform was also able to successfully differentiate very high CRP concentrations (e.g., >10-500 ug/mL) from the hs-CRP range. This mobile, cost-effective and quantitative particle agglutination assay can be useful for various point-of-care sensing needs and global health related applications.

Development of innovative catalysts for the hydrodechlorination to fluoroethers

Publisher: name: amsdottorato
Year: 2014
Subjects: CHIM/04 Chimica industriale

description: In this work the hydrodechlorination of CF3OCFClCF2Cl to produce unsaturated CF3OCF=CF2 was studied over a series of supported metal catalysts. Currently this molecule is produced from the precursor CF3OCFClCF2Cl by dechlorination with zinc powder. An important cost on the economic and environmental balance is represents by the large amount of ZnCl2 produced and to be disposed of. A new approach, based on gas-phase hydrodechlorination over supported catalysts can lead to a new sustainable process. 
During the feasibility step of this project, substantially two kind of materials were studied: metals supported over activated carbon and Pd/Cu species supported over MCM-41 mesoporous silica.
Observed catalytic performances were strongly dependent on the metal and support used.
All carbon-supported Ru, Pd, and bimetallic catalysts are fairly active and yielded the target product CF3OCF=CF2, the higher selectivity being obtained with ruthenium- and palladium-based materials. Nevertheless, Ru-based catalysts showed poor stability and this deactivation may be attributed to the deposition of chlorinated organic species blocking the active sites. On the other hand, palladium-containing catalysts showed high stability. Ru/Pd and Pd/Cu bimetallic catalysts exhibited long-term selectivity and stability, highlighting the possibility for these materials to be employed in the CF3OCF=CF2 production process.
During the second part of this thesis, a series of bimetallic meso-structured Pd/Cu MCM-41 catalysts were studies to overcome possible mass transfer limitations. The materials were obtained by different synthesis methods. The incorporation of Pd and Cu during MCM-41 synthesis, did not destroy the typical hexagonal array and ordered pore system of MCM-41. However, the calcination for the removal of the template provoked significant segregation of oxides. The impregnation leads to pore-occlusion and formation of Cu particles and large bimetallic PdCu species. Larger metal particles leads to lower CF3OCFClCF2Cl conversion, while the monometallic particles can decrease the selectivity to CF3OCF=CF2, fostering the dehalogenation to CF3OCH=CF2.

description: Among abiotic stresses, high salinity stress is the most severe environmental stress. High salinity exerts its negative impact mainly by disrupting the ionic and osmotic equilibrium of the cell. In saline soils, high levels of sodium ions lead to plant growth inhibition and even death. Salt tolerance in plants is a multifarious phenomenon involving a variety of changes at molecular, organelle, cellular, tissue as well as whole plant level. In addition, salt tolerant plants show a range of adaptations not only in morphological or structural features but also in metabolic and physiological processes that enable them to survive under extreme saline environments. The main objectives of my dissertation were understanding the main physiological and biomolecular features of plant responses to salinity in different genotypes of horticultural crops that are belonging to different families Solanaceae (tomato) and Cucurbitaceae (melon) and Brassicaceae (cabbage and radish). Several aspects of crop responses to salinity have been addressed with the final aim of combining elements of functional stress response in plants by using several ways for the assessment of plant stress perception that ranging from destructive measurements (eg. leaf area, relative growth rate, leaf area index, and total plant fresh and dry weight), to physiological determinations (eg. stomatal conductance, leaf gas exchanges, water use efficiency, and leaf water relation), to the determination of metabolite accumulation in plant tissue (eg. Proline and protein) as well as evaluation the role of enzymatic antioxidant capacity assay in scavenging reactive oxygen species that have been generated under salinized condition, and finally assessing the gene induction and up-down regulation upon salinization (eg. SOS pathway).

description: We revisit the phenomenon of the resonant transmission of fermionic carriers through a quantum device connected to two contacts with different chemical potentials. We show that, besides the traditional in solid-state physics Landauer-Büttiker approach, this phenomenon can be also described by the non-Markovian master equation for the reduced density matrix of the fermions in the quantum device. We identify validity regions of both approaches in the system parameter space and argue that for large relaxation rates the accuracy of the latter approach greatly exceeds the accuracy of the former.

Constant Flux Relation for diffusion limited cluster-cluster aggregation

description: In a non-equilibrium system, a Constant Flux Relation (CFR) expresses the fact that a constant flux of a conserved quantity exactly determines the scaling of the particular correlation function linked to the flux of that conserved quantity. This is true regardless of whether mean--field theory is applicable or not. We focus on cluster--cluster aggregation and discuss the consequences of mass conservation for the steady state of aggregation models with a monomer source in the diffusion-limited regime. We derive the CFR for the flux-carrying correlation function for binary aggregation with a general scale-invariant kernel and show that this exponent is unique. It is independent of both the dimension and of the details of the spatial transport mechanism, a property which is very atypical in the diffusion-limited regime. We then discuss in detail the ``locality criterion'' which must be satisfied in order for the CFR scaling to be realisable. Locality may be checked explicitly for the mean-field Smoluchowski equation. We show that if it is satisfied at the mean-field level, it remains true over some finite range as one perturbatively decreases the dimension of the system below the critical dimension, $d_c=2$, entering the fluctuation-dominated regime. We turn to numerical simulations to verify locality for a range of systems in one dimension which are, presumably, beyond the perturbative regime. Finally, we illustrate how the CFR scaling may break down as a result of a violation of locality or as a result of finite size effects and discuss the extent to which the results apply to higher order aggregation processes.

description: A Cosmic Ray Test Facility (CRTF) is the first large-scale implementation of a scintillation triggering system based on a new scintillation technique known as START. In START, the scintillation light is collected and transported by WLS optical fibers, while light detection is performed by pairs of avalanche photodiodes with the Metal-Resistor-Semiconductor structure operated in the Geiger mode (MRS APD). START delivers 100% efficiency of cosmic muon detection, while its intrinsic noise level is less than 10^{-2} Hz. CRTF, consisting of 160 START channels, has been continuously operated by the ALICE TOF collaboration for more than 25 000 hours, and has demonstrated a high level of stability. Fewer than 10% of MRS APDs had to be replaced during this period.

Linguistics as a ``special science''. A comparison of Sapir and Fodor
Creators: name: Elffers, Els
Publisher: name: Zenodo
Year: 2019

description: Independently of each other, the linguist-anthropologist Edward Sapir (1884–1939)

and the philosopher of mind Jerry Fodor (1935–2017) developed a similar typol-

ogy of scientific disciplines. “Basic” (Fodor) or “conceptual” (Sapir) sciences (e.g.

physics) are distinguished from “special” (Fodor) or “historical” (Sapir) sciences

(e.g. linguistics). Ontologically, the latter sciences are reducible to the former, but

they keep their autonomy as intellectual enterprises, because their “natural kinds”

are unlike those of the basic sciences. Fodor labelled this view “token physicalism”.

Although Sapir’s and Fodor’s ideas were presented in very different periods of intel-

lectual history (in 1917 and 1974) and in very different intellectual contexts (roughly:

Geisteswissenschaften and logical positivism), the similarity between them is strik-

ing. When compared in detail, some substantial differences can also be observed,

which are mainly related to contextual differences. When applied to linguistics,

Sapir’s and Fodor’s views offer a perspective of autonomy, albeit in different ways:

for Fodor, but not for Sapir, linguistics is a subfield of psychology.

description: Following the Truth and Reconciliation report and Calls to Action, there has been aconcerted effort within Canada to Indigenize the academy. This effort is taking placewithin administration, research, and classroom settings, and with community partnersacross multiple disciplines. The application of these practices and policies often appearsto be a token response rather than one achieving meaningfid change. Through the useof focused auto-ethnography, we discuss our decolonizing pedagogical approach withinpost-secondary classrooms in health sciences, humanities, and social sciences with In­digenous and non-Indigenous students. We propose that relational learning can leadto reconciliatory actions in the classroom.

description: Two-dimensional (2D) surface of the topological materials is an attractive channel for the electrical conduction reflecting the linearly-dispersive electronic bands. By applying a reliable systematic thickness t dependent measurement of sheet conductance, here we elucidate the dimensionality of the electrical conduction paths of a Weyl semimetal Co3Sn2S2. Under the ferromagnetic phase, the 2D conduction path clearly emerges in Co3Sn2S2 thin films, indicating a formation of the Fermi arcs projected from Weyl nodes. Comparison between 3D conductivity and 2D conductance provides the effective thickness of the surface conducting region being estimated to be approximately 20 nm, which is rather thicker than 5 nm in topological insulator Bi2Se3. This large value may come from the narrow gap at Weyl point and relatively weak spin-orbit interaction of the Co3Sn2S2. The emergent surface conduction will provide a pathway to activate quantum and spintronic transport features stemming from a Weyl node in thin-film-based devices.

description: Local bond order parameters based on spherical harmonics, also known as Steinhardt order parameters, are often used to determine crystal structures in molecular simulations. Here we propose a modification of this method in which the complex bond order vectors are averaged over the first neighbor shell of a given particle and the particle itself. As demonstrated using soft particle systems, this averaging procedure considerably improves the accuracy with which different crystal structures can be distinguished.

description: Groundstate magnetism of the one-band Hubbard model on the frustrated square lattice where both nearest-neighbour $t_1$ and next-nearest-neighbour $t_2$ hoppings are considered at half-filling are revisited within mean field approximation. Two new magnetic phases are detected at intermediate strength of Hubbard $U$ and relative strong frustration of $t_2/t_1$, named double-stripe and plaquette antiferromagnetic states, both of which are metallic and stable even at finite temperature and electron doping. The nature of the phase transitions between different phases and the properties of the two new states are analyzed in detail. Our results of various magnetic states emerging from geometric frustration in the minimal model suggests that distinct antiferromagnetism observed experimentally in the parent states of two high-T$_c$ superconducting families, i.e., cuprates and iron-based superconductors, may be understood from a unified microscopic origin, irrespective of orbital degrees of freedom, or hoppings further than next-nearest neighbour, etc.

description: In this article we consider the potential of engaging the First Peoples Principles ofLearning document in Teacher Education in support of the TRC's Calls to Action.Appreciating the need for Indigenous pedagogies in Indigenizing K-12 curriculumin furtherance of the Calls to Action, we consider the contributions and complexitiesof engaging this document developed by Indigenous teachers and knowledge holdersin British Columbia. Through working with Archibald's Indigenous Storywork andIndigenous scholarship, we highlight the complexity of the colonial context of thiswork. Ultimately, we find that the complications are generative and we discuss anapproach to this document that supports the Calls to Action through ethical and re­lational priorities.

Axial invariance of rapidly varying diffusionless motions in the Earth's core interior

Subjects: subject: Geophysics (physics.geo-ph)

description: Geostrophic jets propagating as Alfvén waves are shown to arise ina rapidly rotating spherical shell permeated by a magnetic field among the transient motions set up by an impulsive rotation of the inner core. These axially invariant motions evolve on a time-scale which is short compared to the magnetic diffusion time. The numerical study is taken as illustrative of a more general point: on such a fast time-scale the dimensionless number appropriate to compare the rotation and magnetic forces is independent of the magnetic diffusivity in contrast with the often used Elsasser number. Extension of the analysis to non-axisymmetrical motions is supported by published studies of dynamo models and magnetic instabilities.
Kamloops Agency and the Indian Reserve Commission of 1912-1916
Creators: name: Ignace, Ronald Eric
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis I review and attempt to provide a critical analysis of the work of the Royal Commission on Indian Affairs in the Province of British Columbia, otherwise known as the McKenna-McBride Commission of 1912 to 1916. This Commission was established to review and assess the acreage of land set aside for the use and benefit of the Indians and was empowered to cut-off land from reserves, create new reserves or to add land to existing reserves. The Commission came into existence due to contention of the increasing number of settlers in British Columbia and their governments that there was an excessive amount of valuable land locked up and lying in idle waste within reserves. I have outlined the social events and forces which led up to the formation of the Commission. Ultimately, the Commission represented a small aspect of the struggle between the colonizers and the colonized for the land and its resources.
The Impact of Russian formalism on linguistic structuralism
Creators: name: Karstens, Bart
Publisher: name: Zenodo
Year: 2019

description: The aim of this chapter is to clarify the relation between Russian formalism, a movement in literary studies, and structuralism. Because leading structuralists such as Mukarovsky (linguistics) and Lévi-Strauss (anthropology) defined their approach in opposition to formalism, we may have the impression that structuralism and formalism are fundamentally different. However, on closer inspection, it turns out that Mukarovsky and Lévi-Strauss targeted specific articulations of formalism. There is a third major variant, namely systemic formalism, which escapes their criticism and can be shown to have influenced structuralism in its earliest phase. First, Tynjanov and Jakobson worked together and co-authored an important short programmatic paper. Second, the genesis of Prague School structuralism should be considered a merger of elements stemming from a multitude of directions. If we do so, we can see how ideas derived from systemic formalism fitted in with other constituents of linguistic structuralism, and hence how formalism influenced the latter to a significant degree.

description: In this post-TRC environment, this paper explores how educators are engaging in In­digenizing, decolonizing, or reconciling pedagogical practices in post-secondary insti­tutions that encourage or inhibit transformation. The discussion is based on a researchstudy using talking circles to create a conversation among 34 Indigenous and settlerally educators at the Congress for Humanities and Social Sciences in 2017. We discussthe stories shared by participants within the three themes of responsibility, relationship,and reconstruction. Indigenous and settler ally instructors identify and use opportu­nities for change in classrooms, despite resistance from some students and adminis­trators. We conclude by discussing the implications of these findings fortransformation at student, faculty, and institutional levels.

description: Since the work of Creutz, identifying the group identities for the Abelian Sandpile Model (ASM) on a given lattice is a puzzling issue: on rectangular portions of Z^2 complex quasi-self-similar structures arise. We study the ASM on the square lattice, in different geometries, and a variant with directed edges. Cylinders, through their extra symmetry, allow an easy determination of the identity, which is a homogeneous function. The directed variant on square geometry shows a remarkable exact structure, asymptotically self-similar.

description: Teaching for anticolonial resistance, Indigenization, and reconciliation in a Western post-secondary institution presents integral philosophical, curricular, pedagogical, professional, and personal challenges. With respect to educational philosophy, Indigenous and Western approaches are diametrically opposed, in that Western education compartmentalizes knowledge by subject, while Indigenous philosophies make the funda­mental assertion that knowledge is, by nature, holistic and inter-related (Battiste, 2013; Castagno & Brayboy, 2008; Cherubini, 2009; Deloria & Wildcat, 2001; Haig-Brown, 2008; Morcom, 2017). Compartmentalization is evident in the very structure of the Western post-secondary institu­tion, since universities and colleges are divided into departments and faculties that reflect a fragmented conceptualization and dissemination of knowledge. Often, different faculties are even housed in separate buildings, which further emphasizes this compartmentalization. That structure not only ensures the continued practice of compartmentalizing knowledge, but also makes a general statement about the institution's philosophy of the nature of knowledge (Deloria & Wildcat, 2001; Mor­com, 2017).

H.E.S.S. upper limits for Kepler's supernova remnant

description: Observations of Kepler's supernova remnant (G4.5+6.8) with the H.E.S.S. telescope array in 2004 and 2005 with a total live time of 13 h are presented. Stereoscopic imaging of Cherenkov radiation from extensive air showers is used to reconstruct the energy and direction of the incident gamma rays. No evidence for a very high energy (VHE: >100 GeV) gamma-ray signal from the direction of the remnant is found. An upper limit (99% confidence level) on the energy flux in the range 230 GeV - 12.8 TeV of 8.6 x 10^{-13} erg cm^{-2} s^{-1} is obtained. In the context of an existing theoretical model for the remnant, the lack of a detectable gamma-ray flux implies a distance of at least 6.4 kpc. A corresponding upper limit for the density of the ambient matter of 0.7 cm^{-3} is derived. With this distance limit, and assuming a spectral index Gamma = 2, the total energy in accelerated protons is limited to E_p < 8.6 x 10^{49} erg. In the synchrotron/inverse Compton framework, extrapolating the power law measured by RXTE between 10 and 20 keV down in energy, the predicted gamma-ray flux from inverse Compton scattering is below the measured upper limit for magnetic field values greater than 52 muG.

description: Radiation pressure on dust is thought to play a crucial role in the formation process of massive stars by acting against gravitational collapse onto the central protostar. However, dust properties in dense regions irradiated by the intense radiation of massive protostars are poorly constrained. Previous studies usually assume the standard interstellar dust model to constrain the maximum mass of massive stars formed by accretion, which appears to contradict with dust evolution theory. In this paper, using the fact that stellar radiation exerts on dust simultaneous radiation pressure and radiative torques, we study the effects of grain rotational disruption by radiative torques (RATs) on radiation pressure and explore its implications for massive star formation. For this paper, we focus on the protostellar envelope and adopt a spherical geometry. We find that original large grains of micron-sizes presumably formed in very dense regions can be rapidly disrupted into small grains by RATs due to infrared radiation from the hot dust shell near the sublimation front induced by direct stellar radiation. Owing to the modification in the size distribution by rotational disruption, the radiation pressure opacity can be decreased by a factor of $\sim 3$ from the value expected from the original dust model. However, to form massive stars via spherical accretion, the dust-to-gas mass ratio needs to be reduced by a factor of $\sim 5$ as previously found.
