description: We show that the low temperature electron transport properties of chemically functionalized graphene can be explained as sequential tunneling of charges through a two dimensional array of graphene quantum dots (GQD). Below 15 K, a total suppression of current due to Coulomb blockade through GQD array was observed. Temperature dependent current-gate voltage characteristics show Coulomb oscillations with energy scales of 6.2-10 meV corresponding to GQD sizes of 5-8 nm while resistance data exhibit an Efros-Shklovskii variable range hopping arising from structural and size induced disorder.

description: We analyse the spectral phase diagram of Schrödinger operators $ T +λV$ on regular tree graphs, with $T$ the graph adjacency operator and $V$ a random potential given by iid random variables. The main result is a criterion for the emergence of absolutely continuous (ac) spectrum due to fluctuation-enabled resonances between distant sites. Using it we prove that for unbounded random potentials ac spectrum appears at arbitrarily weak disorder $(λ\ll 1)$ in an energy regime which extends beyond the spectrum of $T$. Incorporating considerations of the Green function's large deviations we obtain an extension of the criterion which indicates that, under a yet unproven regularity condition of the large deviations' 'free energy function', the regime of pure ac spectrum is complementary to that of previously proven localization. For bounded potentials we disprove the existence at weak disorder of a mobility edge beyond which the spectrum is localized.

description: In this work one shows that a generalized non-minimal coupling between geometry and matter is compatible with Starobinsky inflation and leads to a successful process of preheating, a reheating scenario based on the production of massive particles via parametric resonance. The model naturally extends the usual preheating mechanism, which resorts to an {\it ad-hoc} scalar curvature-dependent mass term for a scalar field $χ$, and also encompasses a previously studied preheating channel based upon a non-standard kinetic term.

description: Strain modulated electronic properties of Si/Ge core-shell nanowires along [110] direction were reported based on first principles density-functional theory calculations. Particularly, the energy dispersion relationship of the conduction/valence band was explored in detail. At the Γ point, the energy levels of both bands are significantly altered by applied uniaxial strain, which results in an evident change of band gap. In contrast, for the K vectors far away from Γ, the variation of the conduction/valence band with strain is much reduced. In addition, with a sufficient tensile strain (~1%), the valence band edge (VBE) shifts away from Γ, which indicates that the band gap of the Si/Ge core-shell nanowires experiences a transition from direct to indirect. Our studies further showed that effective masses of charge carriers can be also tuned by the external uniaxial strain. The effective mass of the hole increases dramatically with a tensile strain, while strain shows a minimal effect on tuning the effective mass of the electron. Finally, the relation between strain and the conduction/valence band edge is discussed thoroughly in terms of site-projected wave-function characters.

Prediction of grain structure and texture evolution after high temperature extrusion of aluminum alloys
Creators: name: Khajezade, Ali
Publisher: name: University of British Columbia
Year: 2022

description: To engineer the mechanical response of the material, it is crucial to predict the microstructure after thermomechanical processing and relate properties to the microstructure. In this study, the relationship between the features of the deformed state after axisymmetric extrusion of aluminum at high temperatures (e.g., the subgrain size distribution and the disorientation distribution) and the final recrystallized texture was investigated. It aims to systematically change the features of the deformed state by generating different initial synthetic microstructures and using them as inputs for a phase field model to predict the recrystallized texture. The characteristics of the deformed state and the recrystallized state were analyzed for extruded 3XXX aluminum samples with two different homogenization heat treatments. The subgrain size distribution and disorientation distribution in different texture fibres of the deformed state, i.e., <001>||ED and <111>||ED, were extracted to construct a baseline condition. After verifying that 2D simulations could be used to capture the essential phenomena in 3D, the role of the microstructural features was investigated using 2D simulations. First, the subgrain size distribution and disorientation distribution were changed from baseline condition by ±50% for individual grains with <001>||ED or <111>||ED. Second, for a mixture of grains with <001>||ED and <111>||ED orientations, <111>||ED baseline condition was used, then subgrain size distribution and disorientation distribution were changed by ±50% for <001>||ED grains. Third, an input microstructure from experimental EBSD measurements was simulated. For the first scenario, a narrower distribution and a wider disorientation distribution resulted in a larger final average subgrain size which was rationalized based on the evolution of these microstructural features. For the second scenario, the tail of the subgrain size distribution and the width of disorientation distribution within <001>||ED was found to have a large impact on the final texture. This was explained by the probability of large grains with high angle disorientation in <001>||ED fibres growing preferentially to pinch-off grains with <111>||ED orientations. For the third scenario, only <001>||ED volume fraction could be predicted accurately compared to the experiment. Possible sources of error were identified and discussed.

description: Aims: We study the diffuse X-ray emission observed in the field of view of the pulsar B 0540-69 in the Large Magellanic Cloud (LMC) by XMM-Newton. We want to understand the nature of this soft diffuse emission, which coincides with the superbubble in the HII region N 158, and improve our understanding of the evolution of superbubbles. Methods: We analyse the XMM-Newton spectra of the diffuse emission. Using the parameters obtained from the spectral fit, we perform calculations of the evolution of the superbubble. The mass loss and energy input rates are based on the initial mass function (IMF) of the observed OB association inside the superbubble. Results: The analysis of the spectra shows that the soft X-ray emission arises from hot shocked gas surrounded by a thin shell of cooler, ionised gas. We show that the stellar winds alone cannot account for the energy inside the superbubble, but the energy release of 2 - 3 supernova explosions in the past ~1 Myr provides a possible explanation. Conclusions: The combination of high sensitivity X-ray data, allowing spectral analysis, and analytical models for superbubbles bears the potential to reveal the evolutionary state of interstellar bubbles, if the stellar content is known.

description: Abstract: Ductal carcinoma in situ (DCIS) now represents 20–25% of all ‘breast cancers’ consequent upon detection by population-based breast cancer screening programmes. Currently, all DCIS lesions are treated, and treatment comprises either mastectomy or breast-conserving surgery supplemented with radiotherapy. However, most DCIS lesions remain indolent. Difficulty in discerning harmless lesions from potentially invasive ones can lead to overtreatment of this condition in many patients. To counter overtreatment and to transform clinical practice, a global, comprehensive and multidisciplinary collaboration is required. Here we review the incidence of DCIS, the perception of risk for developing invasive breast cancer, the current treatment options and the known molecular aspects of progression. Further research is needed to gain new insights for improved diagnosis and management of DCIS, and this is integrated in the PRECISION (PREvent ductal Carcinoma In Situ Invasive Overtreatment Now) initiative. This international effort will seek to determine which DCISs require treatment and prevent the consequences of overtreatment on the lives of many women affected by DCIS.

Examining the influence of community context on the development of Foundry Centres : a multiple case study based on community coalition action theory
Creators: name: Berger, Mai
Publisher: name: University of British Columbia
Year: 2022

description: In Canada, community-based, integrated youth services have gained popularity as models of care that have the potential to address some of the longstanding challenges with youth mental health services. While context has been recognized as an important aspect in the implementation of these models, there is a lack of knowledge regarding how different features of community context might influence the way different models of these community-based, integrated youth services develop in general and their integration processes in particular. This study addresses this gap by examining how specific domains of community context influenced the development of Foundry Centres, which are integrated youth services established in different communities across British Columbia through the Foundry initiative. To explore community context further, community coalition action theory (CCAT) was applied as an organizing framework from the community coalition literature. The research described in this thesis emerged from my experience working on an independent developmental evaluation of Foundry’s proof-of-concept phase where new questions came to light during the analysis process. Using a multiple case study approach informed by an ecological perspective, this thesis examined the influence of seven domains of community context on the development of two Foundry Centres. The data used for this study included 50 interviews carried out for the evaluation as well as nine new interviews. Framework analysis revealed that all seven domains of community context influenced the development of the Foundry Centres, with community collaboration, norms and values, and readiness influencing the broadest range of factors associated with development. Moreover, the integration experiences at both centres were highly sensitive to community context, particularly community collaboration, geography, readiness and needs. Overall, the CCAT offered a relevant framework from which to understand the influence of community context on the development of community-based, integrated youth services. Future studies may enhance its relevance by shifting to a more holistic conceptualization of context where the combined effects of contextual domains are assessed. The evidence generated from this research may be used to support and guide future implementations of community-based, integrated youth services that are sensitive to communities’ rich histories and diverse, place-based identities.
"Is it real? 'Cause you're online" : the legacy of postmodern ethics as a critique of metamodernism
Creators: name: Krentz, Courtney
Publisher: name: University of British Columbia
Year: 2022

description: In 1989, the renowned postmodern scholar Linda Hutcheon suggested that the postmodern period had ended and that something new was beginning to take its place. Since this pronouncement, a distinct subset of literary scholarship has devoted itself to theorizing the contemporary, and numerous proposed successors to the postmodern have emerged. This thesis interrogates one such theory: Timotheus Vermeuelen and Robin van den Akker’s metamodernism. Like other theorists of the contemporary, Vermeulen and van den Akker attribute the contemporary period with a particular desire for authenticity and connection which is opposed to the attitudes of irony and nihilism that are typically associated with the postmodern. In their theory, Vermeulen and van den Akker associate this contemporary move to sincerity with a return to or redeployment of modernism. The authors thus place the ideology of postmodernism and modernism on two distinct poles, where the postmodern pole is associated with irony and nihilism and the modern pole is associated with earnest enthusiasm. Vermeulen and van den Akker argue that contemporary attitudes navigate the space between postmodern irony and modern enthusiasm by oscillating between them, tending at some times towards irony and at others towards earnestness. In this thesis, I argue that Vermeulen and van den Akker oversimplify the postmodern to only its most negative traits, and in doing so, they overlook how postmodernism has actually impacted our current historical moment. By analyzing first a canonical postmodern text (i.e., Kurt Vonnegut’s Slaughterhouse Five) through the lens of Hutcheon’s historiographic metafiction, I demonstrate that postmodern works have a more ethical potential than the metamodern framework allows. I then turn to a contemporary work of metafiction (i.e., Childish Gambino’s Because the Internet) to illustrate how, when its ethical potential is considered, postmodernism can be understood to have a more nuanced and productive influence on the contemporary.

description: A two-fluid dark matter model, in which dark matter is represented as a two-component fluid thermodynamic system, without interaction between the constituent particles of different species, and with each distinct component having a different four-velocity, was recently proposed in Harko & Lobo, [Phys. Rev. D83, 124051 (2011)]. In the present paper we further investigate the two-fluid dark matter model, by assuming that the two dark matter components are pressureless, non-comoving fluids. For this particular choice of the equations of state the dark matter distribution can be described as a single anisotropic fluid, with vanishing tangential pressure, and non-zero radial pressure. We investigate the properties of this model in the region of constant velocity galactic rotation curves, where the dynamics of the test particles is essentially determined by the dark matter only. By solving the general relativistic equations of mass continuity and hydrostatic equilibrium we obtain the geometric and physical parameters of the dark matter halos in the constant velocity region in an exact analytical form. The general, radial coordinate dependent, functional relationship between the energy density and the radial pressure is also determined, and it differs from a simple barotropic equation of state.

description: We perform the Hamiltonian analysis for a nonprojectable Horava model whose potential is composed of R and R^2 terms. We show that Dirac's algorithm for the preservation of the constraints can be done in a closed way, hence the algebra of constraints for this model is consistent. The model has an extra, odd, scalar mode whose decoupling limit can be seen in a linear-order perturbative analysis on weakly varying backgrounds. Although our results for this model point in favor of the consistency of the Hořava theory, the validity of the full nonprojectable theory still remains unanswered.

description: Japan faces many challenges related to its aging society, including increasing rates of cognitive decline in the population and a shortage of caregivers. Efforts have begun to explore solutions using artificial intelligence (AI), especially socially embodied intelligent agents and robots that can communicate with people. Yet, there has been little research on the compatibility of these agents with older adults in various everyday situations. To this end, we conducted a user study to evaluate a robot that functions as a facilitator for a group conversation protocol designed to prevent cognitive decline. We modified the robot to use backchannelling, a natural human way of speaking, to increase receptiveness of the robot and enjoyment of the group conversation experience. We conducted a cross-generational study with young adults and older adults. Qualitative analyses indicated that younger adults perceived the backchannelling version of the robot as kinder, more trustworthy, and more acceptable than the non-backchannelling robot. Finally, we found that the robot's backchannelling elicited nonverbal backchanneling in older participants.

description: What are the properties of accretion flows in the vicinity of coalescing supermassive black holes (SBHs)? The answer to this question has direct implications for the feasibility of coincident detections of electromagnetic (EM) and gravitational wave (GW) signals from coalescences. Such detections are considered to be the next observational grand challenge that will enable testing general relativity in the strong, nonlinear regime and improve our understanding of evolution and growth of these massive compact objects. In this paper we review the properties of the environment of coalescing binaries in the context of the circumbinary disk and hot, radiatively inefficient accretion flow models and use them to mark the extent of the parameter space spanned by this problem. We report the results from an ongoing, general relativistic, hydrodynamical study of the inspiral and merger of black holes, motivated by the latter scenario. We find that correlated EM+GW oscillations can arise during the inspiral phase followed by the gradual rise and subsequent drop-off in the light curve at the time of coalescence. While there are indications that the latter EM signature is a more robust one, a detection of either signal coincidentally with GWs would be a convincing evidence for an impending SBH binary coalescence. The observability of an EM counterpart in the hot accretion flow scenario depends on the details of a model. In the case of the most massive binaries observable by the Laser Interferometer Space Antenna, upper limits on luminosity imply that they may be identified by EM searches out to z~0.1-1. However, given the radiatively inefficient nature of the gas flow, we speculate that a majority of massive binaries may appear as low luminosity AGN in the local universe.

Non-local electrical conductivity in PdCoO₂
Creators: name: Baker, Graham
Publisher: name: University of British Columbia

description: Electrical conduction becomes non-local when an inhomogeneous electronic distribution is induced with a spatial variation shorter than the mean free path (MFP) between momentum-relaxing scattering processes. Two important methods of inducing such a distribution are via the size and skin effects. In the size effect, one or more dimensions of a medium are reduced below the MFP. The scattering of electrons from the medium's boundaries then induces an inhomogeneous electronic distribution under an applied direct current. In the skin effect, the exponential decay of alternating electromagnetic fields as they propagate into the medium gives rise to a so-called skin layer. The electronic distribution within the skin layer becomes inhomogeneous as the skin depth falls below the MFP. Here we study the size and skin effects in PdCoO₂, both experimentally and theoretically. While previous theoretical treatments of non-local electrical conductivity have assumed a free-electron dispersion, we observe that the anisotropic Fermi surface (FS) in PdCoO₂ results in behaviour that is incompatible with this assumption. Measurements of the size effect in PdCoO₂ revealed two novel phenomena, both of which are symmetry-forbidden for local conduction: anisotropy in the in-plane longitudinal resistivity, and a non-zero transverse resistivity at zero magnetic field. We developed a theory of the size effect for arbitrary FS geometry and used it to reproduce the key features of these measurements. Motivated by recent interest in the possibility that electrons in solids may behave viscously as a result of frequent internal momentum-conserving scattering, we developed a generalized theory of the skin effect, taking into account separate rates of momentum-conserving and momentum-relaxing scattering for arbitrary FS geometry. For an isotropic FS, our theory encompasses several known limiting behaviours. For anisotropic FSs, we explored geometries which lead to changes in the scaling of the surface impedance. By applying bolometric broadband microwave spectroscopy, we studied the skin effect in PdCoO₂ for three different directions of electromagnetic propagation. Using symmetry-based arguments, we determined that our measurements were neither in the local nor purely viscous regime. We argued instead that the data demonstrate a novel, predominantly ballistic effect as a result of the faceted FS.

description: Our modified gravity theory (MOG) is a gravitational theory without exotic dark matter, based on an action principle. MOG has been used successfully to model astrophysical phenomena such as galaxy rotation curves, galaxy cluster masses, and lensing. MOG may also be able to account for cosmological observations. We assume that the MOG point source solution can be used to describe extended distributions of matter via an appropriately modified Poisson equation. We use this result to model perturbation growth in MOG and find that it agrees well with the observed matter power spectrum at present. As the resolution of the power spectrum improves with increasing survey size, however, significant differences emerge between the predictions of MOG and the standard LCDM model, as in the absence of exotic dark matter, oscillations of the power spectrum in MOG are not suppressed. We can also use MOG to model the acoustic power spectrum of the cosmic microwave background. A suitably adapted semi-analytical model offers a first indication that MOG may pass this test, and correctly model the peak of the acoustic spectrum.

description: The theoretical and methodological foundations of the formation of the physical culture of university students are methodological approaches that ensure the interdependence and integrity of the process, principles that reflect the content and characteristics of the approaches. The field of categorical research on the formation of physical culture of a university student includes the justification of the content of the concepts of "personal physical culture", "physical culture", "physical culture and valeological competence". The process of forming the physical culture of university students is effective if it is built on the following principles: a unity of systematic, cultural, activity-based, competence-based, innovative and student-oriented approaches to the formation of physical education. physical culture of the student; innovativeness of goal setting and its formation. The systematic approach serves as a methodological strategy in the formation of the physical culture of the student, and other approaches are combined with it. In the process of scientific work, a theoretical and methodological model of the formation of the physical culture of the student was developed.

description: Αντικείμενο της παρούσας εργασίας αποτελεί η εξέταση των αρχών που διέπουν διαχρονικά τις προσλήψεις στον Δημόσιο Τομέα καθώς και η διερεύνηση του θεσμικού ρόλου του Ανώτατου Συμβουλίου Επιλογής Προσωπικού (AΣEΠ), από την έναρξη της λειτουργίας του έως και σήμερα, με τη θέσπιση του νέου νομοθετικού πλαισίου για τις προσλήψεις στο Δημόσιο, τον νόμο 4765/2021. Η πρόσβαση στις δημόσιες θέσεις θεωρείται ένα ιδιαίτερα σημαντικό ζήτημα, επειδή η ποιότητα του ανθρώπινου δυναμικού συνδέεται στενά με την αποτελεσματικότητα της δημόσιας διοίκησης και συνεπώς, με την επίτευξη του καίριου στόχου της εξυπηρέτησης του δημοσίου συμφέροντος. Επιπλέον, καθίσταται ζήτημα συνταγματικού ενδιαφέροντος αφού εμπλέκονται σε αυτήν τη διαδικασία, εκτός από τη δημοκρατική αρχή και την αρχή του κράτους δικαίου, συνταγματικές αρχές, όπως η αξιοκρατία και η ισότητα αλλά και αρχές που απορρέουν έμμεσα από το Σύνταγμα, όπως η αντικειμενικότητα, η διαφάνεια και η αποτελεσματικότητα της δράσης της δημόσιας διοίκησης, οι οποίες δημιουργούν ένα δεσμευτικό πλαίσιο για τον νομοθέτη αλλά και για τη Διοίκηση, κατά την επιλογή και υλοποίηση των συστημάτων πρόσληψης. Η μεθοδολογία που εφαρμόστηκε για την προσέγγιση του θέματος της παρούσας εργασίας είναι η βιβλιογραφική επισκόπηση πρωτογενών και δευτερογενών πηγών καθώς και η σύνθεση και ερμηνεία των στοιχείων που απορρέουν από αυτές, σε συνδυασμό με νομοθετικά κείμενα και τη νομολογία. Στόχος της εργασίας είναι να μελετηθούν εκτενώς οι αρχές που διέπουν τις προσλήψεις, όπως οι συνταγματικά κατοχυρωμένες αρχές της αξιοκρατίας, της ίσης ευκαιρίας συμμετοχής, της αντικειμενικότητας και της διαφάνειας καθώς και η επίτευξη των σκοπών τους, μέσω των μεταρρυθμίσεων που επέφερε ο ν.4765/2021, ο οποίος εξετάζεται ως μελέτη περίπτωσης. Επιπλέον, θα μελετηθεί η αποστολή, το πεδίο δράσης και η εξέλιξη του ΑΣΕΠ, από τη σύστασή της ως ανεξάρτητη αρχή με τον ν.2190/1994 έως σήμερα, και η οποία αποτελεί, έκτοτε, τον θεσμικό εγγυητή της τήρησης των ανωτέρω αρχών αλλά και του δικαιώματος των πολιτών να αποκτούν πρόσβαση στη δημόσια διοίκηση με ισότιμο και αξιοκρατικό τρόπο. Βασικό συμπέρασμα της εργασίας είναι ότι, με τον ν.4765/2021 και την εφαρμογή ενός ενιαίου συστήματος προσλήψεων, μέσω του πανελληνίου γραπτού διαγωνισμού ως της κύριας μεθόδου επιλογής για όλες τις κατηγορίες προσωπικού, το υφιστάμενο σύστημα προσλήψεων αποκτά έναν πιο σύγχρονο χαρακτήρα χωρίς, όμως, να μεταβάλλεται ριζικά. Επιπλέον, το ΑΣΕΠ ενισχύεται σημαντικά στον θεσμικό του ρόλο, προκειμένου να επιτύχει αποτελεσματικότερα τους στόχους του.
Acceleration of colliding shells around a black hole: Validity of the test particle approximation in the Banados-Silk-West process

description: Recently, Banados, Silk and West (BSW) showed that the total energy of two colliding test particles has no upper limit in their center of mass frame in the neighborhood of an extreme Kerr black hole, even if these particles were at rest at infinity in the infinite past. We call this mechanism the BSW mechanism or BSW process. The large energy of such particles would generate strong gravity, although this has not been taken into account in the BSW analysis. A similar mechanism is seen in the collision of two spherical test shells in the neighborhood of an extreme Reissner-Nordström black hole. In this paper, in order to draw some implications concerning the effects of gravity generated by colliding particles in the BSW process, we study a collision of two spherical dust shells, since their gravity can be exactly treated. We show that the energy of two colliding shells in the center of mass frame observable from infinity has an upper limit due to their own gravity. Our result suggests that an upper limit also exists for the total energy of colliding particles in the center of mass frame in the observable domain in the BSW process due the gravity of the particles.

description: It is well known that the quantum Zeno effect can protect specific quantum states from decoherence by using projective measurements. Here we combine the theory of weak measurements with stabilizer quantum error correction and detection codes. We derive rigorous performance bounds which demonstrate that the Zeno effect can be used to protect appropriately encoded arbitrary states to arbitrary accuracy, while at the same time allowing for universal quantum computation or quantum control.
