description: The role of baryonic physics, star formation, and stellar feedback, in shaping the galaxies and their host halos is an evolving topic. The dark matter aspects are illustrated in this work by showing distribution features in a Milky-Way-sized halo. We focus on the halo morphology, geometry, and profile as well as the phase space distribution using one dark matter only and five hydrodynamical cosmological high-resolution simulations of the same halo with different subgrid prescriptions for the baryonic physics (Kennicut versus multi-freefall star formation and delayed cooling versus mechanical supernovae feedback). If some general properties like the relative halo-galaxy orientation are similar, the modifications of the gravitational potential due to the presence of baryons are found to induce different dark matter distributions (rounder and more concentrated halo). The mass density profile as well as the velocity distribution are modified distinctively according to the specific resulting baryonic distribution highlighting the variability of those properties (e.g inner power index from 1.3 to 1.8, broader speed distribution). The uncertainties on those features are of paramount importance for dark matter phenomenology, particularly when dealing with dark matter dynamics or direct and indirect detection searches. As a consequence, dark matter properties and prospects using cosmological simulations require improvement on baryonic physics description. Modeling such processes is a key issue not only for galaxy formation but also for dark matter investigations.

Environmental politics after disaster strikes : the cultural dynamics of public participation and mobilization
Creators: name: Chewinski, Max
Publisher: name: University of British Columbia
Year: 2022

description: A central goal of my dissertation research is to better understand how cultural dynamics shape environmental politics and generate inequalities in decision-making processes. I draw on the 2014 Mount Polley mining disaster and subsequent water management plans to examine public participation and mobilization in Likely, British Columbia. I use 42 semi-structured interviews, 4,723 pages of documents including emails and letters associated with Mount Polley’s public liaison committee, and 208 news articles to assess the relationship between culture, inequality, and environmental politics. I begin by adopting a procedural justice framework to examine how cultural dynamics facilitate or constrain meaningful opportunities for residents to shape decision-making. I find that strategies of agenda denial (nonrecognition and symbolic placation) prevent residents from meaningfully participating in the definition of environmental problems and their proposed solutions. I develop the concept of manufactured confusion to highlight inequalities in meaning-making resources and capabilities. Manufactured confusion is a taken for granted condition that emerges from three practices: (1) a reliance on a large volume of scientific information (2) insufficient resources to interpret complex scientific data and (3) insufficient opportunities to discuss scientific data. Next, I examine how emotions shape the social relations and practices that structure environmental deliberations. I find that trauma from the disaster and experiences of procedural injustice sparked intense and durable negative emotions including anger, animosity, fear, and frustration. The presence of unmanaged negative emotions influences two related outcomes. First, negative emotions facilitate the emergence of polarization as empathy walls between stakeholders are secured instead of scaled. Second, often linked to the first, negative emotions facilitate disengagement as participants seek to avoid emotional harm. Finally, I shift to examine how cultural context and capacity prevent social movement emergence and channel residents towards quiet mobilization. I find that a cultural disavowal of contentious collective action, the presence of community corrosion, and the absence of formal mobilizing structures inhibit contentious mobilization. In its place, individual and collective forms of quiet mobilization emerge in the face of mounting environmental risks. Quiet mobilization includes civic practices such as writing op-eds, letters, launching public awareness campaigns and initiating environmental permit appeals.

description: We present stellar parameters and abundances of 13 elements for 18 very metal-poor (VMP; [Fe/H] $<$ -2.0) stars, selected as extremely metal-poor (EMP; [Fe/H] $<$ -3.0) candidates from SDSS and LAMOST survey. High-resolution spectroscopic observations were performed using GEMINI-N/GRACES. We find ten EMP stars among our candidates, and we newly identify three carbon-enhanced metal poor (CEMP) stars with [Ba/Fe] $<$ 0. Although chemical abundances of our VMP/EMP stars generally follow the overall trend of other Galactic halo stars, there are a few exceptions. One Na-rich star ([Na/Fe] = +1.14) with low [Mg/Fe] suggests a possible chemical connection with second-generation stars in a globular cluster. The progenitor of an extremely Na-poor star ([Na/Fe] = -1.02) with an enhancement of K- and Ni-abundance ratios may have undergone a distinct nucleosynthesis episode, associated with core-collapse supernovae (CCSNe) having a high explosion energy. We have also found a Mg-rich star ([Mg/Fe] = +0.73) with slightly enhanced Na and extremely low [Ba/Fe], indicating that its origin is not associated with neutron-capture events. On the other hand, the origin of the lowest Mg abundance ([Mg/Fe] = -0.61) star could be explained by accretion from a dwarf galaxy, or formation in a gas cloud largely polluted by SNe Ia. We have also explored the progenitor masses of our EMP stars by comparing their chemical-abundance patterns with those predicted by Population III SNe models, and find a mass range of 10 - 26 $M_\odot$, suggesting that such stars were primarily responsible for the chemical enrichment of the early Milky Way.

description: In this work, I propose a scheme about a single graphene nanoribbon (GNR) emitter in a microcavity, and focus on a fully-quantum-mechanical treatment model with the excitonic interaction included to investigate the photon properties and lasing action. When the single armchair-edged GNRs (AGNRs) microcavity system is pumped, the exciton-photon coupling provides more photons and enhances the photon emission process, making it essentially a lasing object. The theoretical results demonstrated that single AGNR in a semiconductor microcavity system maybe serve as a nanolaser with ultralow lasing threshold.

description: Controlling and harvesting solar radiation pressure is a significant challenge, however, there are few potential solutions, which are suitable for several key applications. In this study, an electrically tunable plasmonic metasurface is designed for the visible spectrum. Moreover, the normal and the tangential optical forces acting on the metasurface are calculated. Whilst presenting high efficiency in the anomalous reflection, the designed active metasurface provides tunability of optical forces acting on the metasurface. The metasurface is composed of tapered silver cells embedded on top of the graphene layer with 20 layers of graphene sheets. Hence, by tuning the Fermi level of graphene sheets, the transferred momentum to the metasurface can be controlled. Our results can provide a suitable platform for optical force control desired in tunable radiation pressure harvesting, micro vehicles, solar sailing and optical tweezers.

We compare the results with the experimental data in different ranges of photon virtualities. The obtained transition form factors are used to determine the $π^0$, $η$ and $η^\prime$ pole terms in the hadronic light-by-light scattering contribution to the anomalous magnetic moment of the muon.

Subjects: subject: Erdbebensicherheit/Istanbul

description: In der vorliegenden Arbeit wird der erdbebengerechte soziale Wohnbau in Istanbul behandelt. Um dem Leser die Möglichkeit für ein besseres Verständnis der behandelten Thematik zu geben, sind in dieser Arbeit einige Themenbereiche des Erdbebens kurz erläutert. Des Weiteren werden bedeutende Aspekte der türkischen Baukultur und ihrer Entwicklung aufgezeigt. Im Rahmen dieser Arbeit wird die erdbebengerechte Bebauung, Planung und ihre immense Bedeutung im Bauwesen beschrieben. Die vorliegende Arbeit soll einerseits einen Einblick in die türkische Baukultur und ihre Entwicklung und andererseits die Erdbebenperformance sowie ihre wirtschaftliche Rentabilität des sozialen Wohnbaues aufzeigen. Dabei werden verschiedene Bauwerke entworfen, mit der Behörde in Istanbul abgestimmt und nach ihrer seismischen Performance überprüft. Eines dieser fiktiven Bauten ist nach der türkischen Baukultur entworfen, die weiteren zwei Bauwerke dienen einer möglichen Steigerung der Erdbebensicherheit. Der Vergleich der Objekte untereinander nach ihrer Erdbebenperformance und ihren Rohbaukosten zeigt, dass durch eine geringe Erhöhung der Bausumme pro m2 die Sicherheit gesteigert werden kann. Die Kompensierung der Erdbebenkräfte erfolgt in der Stahlbetonskelettbauweise ohne Wandscheiben durch große Verformungen. Diese Verformungen stellen eine Gefahr für die Mauerwerksausfachung und die Schadensbegrenzung dar.
description: In this present study, an earthquake resistant social housing model in Istanbul will be presented. For a better understanding of this subject, the reader will be given some brief insights into several aspects of the earthquake subject. Furthermore, fundamental aspects of the Turkish architectural culture and its history are pointed out. Within the framework of this work, earthquake-resistant buildings, their planning and vehement meaning in construction industry are described. The present work should, on the one hand, give insight into the Turkish architectural culture and its development and, on the other hand, illustrate the earthquake performance and economic viability of social residential building. Three different structures are designed, approved by the municipality in Istanbul and tested for their seismic performance. One of these fictitious buildings is designed according to the Turkish architectural manner. The other two buildings serve to potentially increase earthquake performance. The comparison of these objects according to their seismic performance and the costs of their shell construction, shows that the performance can be increased by a small increase in the construction cost of a m2. Earthquake forces are compensated with large deformations of the reinforced- concrete skeleton construction without shear walls. These deformations present a serious danger to the infilling masonry and to damage limitation.

description: The interference fragmentation function translates the fragmentation of a quark with a transverse projection of the spin into an azimuthal asymmetry of two final-state hadrons. In e+e- annihilation the product of two interference fragmentation functions is measured. We report nonzero asymmetries for pairs of charge-ordered pi+pi- pairs, which indicate a significant interference fragmentation function in this channel. The results are obtained from a 672 fb-1 data sample that contains 711 \times 106 pi+pi- pairs and was collected at and near the ?(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e+e- collider.

Cultivating food justice in Vancouver, BC
Creators: name: Hamdon, Carly
Publisher: name: University of British Columbia
Year: 2022

description: Food Justice activism transforms poor communities of colour in the United States by increasing access to fresh, nutritious food. While the language of food justice has been incorporated into Canada, few studies have empirically analyzed how Canadian food activists interpret its central tenets and goals. I interviewed volunteers, committee members, and the lead organizer of a justice-oriented local food organization that implemented an emergency food program in Vancouver’s Downtown Eastside during the 2020-2021 COVID-19 pandemic. My findings show that participants understand and enact food justice in two different but complementary ways. First, participants respond to the stigma that free food recipients face by strategically redefining the meaning of free food recipients. This redefinition occurs through four mechanisms of destigmatization: combining social categories, removing blame, drawing equivalences, and restoring agency. Second, when conceptualizing an ideal local food organization, participants demonstrate a thick democratic imagination. Specifically, they visualize a grassroots, anti-bureaucratic, and culturally inclusive food hub that facilitates food education through a community kitchen and garden. Moreover, participants prioritize Indigenous led-food initiatives and systems, revealing a thick and imaginative democratic imagination. The significance of these findings is twofold. On the one hand, my research reveals how the availability of symbolic resources (e.g., the concept of a shared community) facilitates the destigmatization of low-status groups. On the other hand, my research demonstrates that food activists on Vancouver’s Downtown Eastside have thick democratic imaginations and that these imaginations expand when accounting for Indigenous reconciliation. Altogether these findings show that while interpretations of food justice are contextual, it retains its transformative potential.
Flow imaging as an alternative to pressure transducers through vision transformers and convolutional neural networks

description: In this work, we propose a framework whereby flow imaging data is leveraged to extract relevant information from flowfield visualizations. To this end, a vision transformer (ViT) model is developed to predict the unsteady pressure distribution over an airfoil under dynamic stall from images of the flowfield. The network is capable of identifying relevant flow features present in the images and associate them to the airfoil response. Results demonstrate that the model is effective in interpolating and extrapolating between flow regimes and for different airfoil motions, meaning that ViT-based models may offer a promising alternative for sensors in experimental campaigns and for building robust surrogate models of complex unsteady flows. In addition, we uniquely treat the image semantic segmentation as an image-to-image translation task that infers semantic labels of structures from the input images in a supervised way. Given an input image of the velocity field, the resulting convolutional neural network (CNN) generates synthetic images of any corresponding fluid property of interest. In particular, we convert the velocity field data into pressure in order to subsequently estimate the pressure distribution over the airfoil in a robust manner.

description: Diese Arbeit beschäftigt sich mit der Frage, wie es möglich ist, Armut mit Hilfe eines dynamischen Optimierungsmodells zu dekonzentrieren. Der Kernansatz hierzu ist es, arme Familien in mittelständische Gegenden umzusiedeln. Ein Hauptproblem dabei ist, dass dadurch eine Flucht des Mittelstandes ausgelöst werden kann. Für eine realistische Problemformulierung müssen viele verschiedene Parameter berücksichtigt werden. Das Problem wird mit Methoden der Optimalen Kontrolltheorie analysiert. Hierbei wird die MATLAB Toolbox OCMat verwendet, welche von Dieter Grass entwickelt wurde, der zur Zeit in der Forschungsgruppe Operations Research und Kontrollsysteme an der Technischen Universität Wien arbeitet. Das zugrundeliegende Basismodell aus früheren Studien wird erweitert, um zu sehen, wie die Gleichgewichte und die optimalen Lösungen von den getroffenen Modellannahmen abhängen. Des Weiteren wird ein Fall, in dem eine sogenannte DNSS Kurve auftritt, betrachtet.
description: This thesis deals with a dynamic optimization model aiming at deconcentrating poverty. The core approach is moving poor families to middle-class areas, which may induce middle-class flight. A reasonable model formulation requires that many different parameters have to be taken into consideration. The problem is analyzed by methods of optimal control theory using the MATLAB toolbox OCMat developed by Dieter Grass from the research unit for Operations Research and Control Systems at the Vienna University of Technology. The basic model as described in previous work will be extended in order to see how the equilibria and the optimal solutions depend on the model assumptions. Furthermore, the case of a so-called DNSS curve will be analyzed.

description: Weyl geometry is a natural extension of conformal geometry with Weyl covariance mediated by a Weyl connection. We generalize the Fefferman-Graham (FG) ambient construction for conformal manifolds to a corresponding construction for Weyl manifolds. We first introduce the Weyl-ambient metric motivated by the Weyl-Fefferman-Graham (WFG) gauge. From a top-down perspective, we show that the Weyl-ambient space as a pseudo-Riemannian geometry induces a codimension-2 Weyl geometry. Then, from a bottom-up perspective, we start from promoting a conformal manifold into a Weyl manifold by assigning a Weyl connection to the principal $\mathbb{R}_+$-bundle realizing a Weyl structure. We show that the Weyl structure admits a well-defined initial value problem, which determines the Weyl-ambient metric. Through the Weyl-ambient construction, we also investigate Weyl-covariant tensors on the Weyl manifold and define extended Weyl-obstruction tensors explicitly.

Radio Galaxy NGC 1265 unveils the Accretion Shock onto the Perseus Galaxy Cluster

description: We present a consistent 3D model for the head-tail radio galaxy NGC 1265 that explains the complex radio morphology and spectrum by a past passage of the galaxy and radio bubble through a shock wave. Using analytical solutions to the full Riemann problem and hydrodynamical simulations, we study how this passage transformed the plasma bubble into a toroidal vortex ring. Adiabatic compression of the aged electron population causes it to be energized and to emit low-surface brightness and steep-spectrum radio emission. The large infall velocity of NGC 1265 and the low Faraday rotation measure values and variance of the jet strongly argue that this transformation was due to the accretion shock onto Perseus situated roughly at R_200. Estimating the volume change of the radio bubble enables inferring a shock Mach number of M = 4.2_{-1.2}^{+0.8}, a density jump of 3.4_{-0.4}^{+0.2}, a temperature jump of 6.3_{-2.7}^{+2.5}, and a pressure jump of 21.5 +/- 10.5 while allowing for uncertainties in the equation of state of the radio plasma and volume of the torus. Extrapolating X-ray profiles, we obtain upper limits on the gas temperature and density in the infalling warm-hot intergalactic medium of kT < 0.4 keV and n < 5e-5 / cm^3. The orientation of the ellipsoidally shaped radio torus in combination with the direction of the galaxy's head and tail in the plane of the sky is impossible to reconcile with projection effects. Instead, this argues for post-shock shear flows that have been caused by curvature in the shock surface with a characteristic radius of 850 kpc. The energy density of the shear flow corresponds to a turbulent-to-thermal energy density of 14%. The shock-injected vorticity might be important in generating and amplifying magnetic fields in galaxy clusters. Future LOFAR observations of head-tail galaxies can be complementary probes of accretion shocks onto galaxy clusters.

description: Both ultralight dark matter and exploring the quantum nature of black holes are all topics of great interest in gravitational wave astronomy at present. The superradiant instability allows an exotic compact object (ECO) to be surrounded by an ultralight boson cloud, which leads to the emission of gravitational waves and further triggers rich dynamical effects. In this paper, we study the gravitational effects of superradiant instabilities by calculating the energy fluxes of gravitational waves emitted from ultralight scalar dark matter fields by solving the Teukolsky equation in the background of a massive ECO phenomenologically described by a Kerr geometry with a reflective boundary condition at its physical boundary. We find that both the amplitude and phase of the reflectivity will either suppress or enhance the energy flux of GWs by several orders of magnitude if $Mμ\gtrsim 0.5$ where $M$ and $μ$ are the mass of ECO and boson, respectively. However, the modifications to energy flux are negligible if $M μ\lesssim 0.5$. Our results suggest that reflectivity will play a significant role in the near-horizon physics of ECO.

description: The fifth iteration of the Sloan Digital Sky Survey (SDSS-V) is set to obtain optical and near-infrared spectra of $\sim$5 million stars of all ages and masses throughout the Milky Way. As a part of these efforts, APOGEE & BOSS Young Star Survey (ABYSS) will observe $\sim10^5$ stars with ages $<$30 Myr that have been selected using a set of homogeneous selection functions that make use of different tracers of youth. The ABYSS targeting strategy we describe in this paper is aimed to provide the largest spectroscopic census of young stars to-date. It consists of 8 different types of selection criteria that take the position on the HR diagram, infrared excess, variability, as well as the position in phase space in consideration. The resulting catalog of $\sim$200,000 sources (of which a half are expected to be observed) provides representative coverage of the young Galaxy, including both nearby diffuse associations as well as more distant massive complexes, reaching towards the inner Galaxy and the Galactic center.

Field-Induced Spin-Exciton Condensation in dx2-y2-wave Superconducting CeCoIn5

description: The implications of the spin exciton mechanism are exposed in the context of a Spin Density Wave (SDW) instability occurring inside the superconducting phase of a layered heavy electron compound. In this model a magnetic field serves as a tuning parameter bringing the system to the point where the transverse spin correlations are enhanced due to dx2 -y2 -wave superconductivity and induces an instability to a phase with coexisting superconductivity and SDW order. The model considers electrons in a crystal with antiferromagnetic interactions and provides restrictions on the Fermi surface characteristics and on the ordering wave-vector (that can be commensurate or incommensurate close to commensuration). The applications of the model are addressed to the low-temperature/high-magnetic-field phase of CeCoIn5 [M. Kenzelmann et al., Science 321, 1652 (2008), Phys. Rev. Lett. 104, 127001 (2010)].

Interannual variability of carbon dioxide (CO₂) and methane (CH₄) fluxes in a temperate bog over a 5-year period
Creators: name: Satriawan, Tin
Publisher: name: University of British Columbia
Year: 2022

description: Peatland rewetting, which is a management effort to restore water levels in previously drained peatlands, is important for re-establishing the role of peatlands as carbon (C) sinks. Since rewetted peatlands often have a highly variable response to year-to-year changes in climatic conditions and to functional changes, long term studies of C fluxes are needed in these ecosystems. Here, we evaluated the impact of climate variability and functional change on the interannual variability of CO₂ and CH₄ fluxes at Burns Bog, a rewetted temperate bog in Canada, based on five years of continuous eddy-covariance measurements. We found that the study site alternated between being an annual-scale net CO₂ sink and source, ranging from -32.6 ± 21.5 (± 95% CI) to 11.9 ± 15.1 g CO₂-C mˉ² yearˉ¹, respectively, while consistently being a CH₄ source, ranging from 11.6 ± 0.7 to 18.0 ± 1.6 g CH₄-C mˉ² yearˉ¹. On a five-year average, CH₄ emissions (13.7 ± 2.5 g CH₄-C mˉ² yearˉ¹; ± SD across years) completely offset the CO₂ sink (-12.3 ± 20.4 g CO₂-C mˉ² yearˉ¹; ± SD across years) on a carbon equivalent basis, resulting in the site losing an average of 1.3 ± 23.9 g C mˉ² yearˉ¹ (± SD across years). This finding indicates that excluding CH₄ fluxes from the net ecosystem C budget results in a significant overestimation of the net C uptake at this peatland site. The bog was the greatest annual CO₂ source in the year with a dry and warm summer, emphasizing the importance of temperature and water table depth at the bog. Regardless of the GHG metrics (i.e., global warming potential or sustained global warming potential) used in calculating the annual CO₂-eq GHG balance, the bog consistently had a positive radiative balance during each year of the study period. Despite mainly acting as a GHG source, the rewetted bog will likely have cooling effect on climate over long timescales compared to drained bogs that are large CO₂ sources.
Wavelet analysis of the multivariate fractional Brownian motion

description: The work developed in the paper concerns the multivariate fractional Brownian motion (mfBm) viewed through the lens of the wavelet transform. After recalling some basic properties on the mfBm, we calculate the correlation structure of its wavelet transform. We particularly study the asymptotic behavior of the correlation, showing that if the analyzing wavelet has a sufficient number of null first order moments, the decomposition eliminates any possible long-range (inter)dependence. The cross-spectral density is also considered in a second part. Its existence is proved and its evaluation is performed using a von Bahr-Essen like representation of the function $\sign(t) |t|^α$. The behavior of the cross-spectral density of the wavelet field at the zero frequency is also developed and confirms the results provided by the asymptotic analysis of the correlation.

description: Radio Frequency Interference (RFI) of impulsive nature is created by sources like sparking on high-power transmission lines due to gap or corona discharge and automobile sparking, and it affects the entire observing frequency bands of low-frequency radio telescopes. Such RFI is a significant problem at the Upgraded Giant Metrewave Radio Telescope (uGMRT). A real-time RFI filtering scheme has been developed and implemented to mitigate the effect on astronomical observations. The scheme works in real-time on pre-correlation data from each antenna and allows the detection of RFI based on median absolute deviation statistics. The samples are identified as RFI based on user-defined thresholds and are replaced by digital noise, a constant or zeros. We review the testing and implementation of this system at the uGMRT. We illustrate the effectiveness of the filtering for continuum, spectral line and time-domain data. The real-time filter is released for regular observations in the bands falling in 250 - 1450 MHz, and recent observing cycles show growing usage. Further, we explain the relevance of the released system to the Square Kilometer Array (SKA) receiver chain and possible ways of implementation to meet the computational requirements.

description: We study the gravitational wave memory effect in spacetimes related to flat space by a conformal transformation. The discussion is general but the gravitational wave length scale is assumed to be small compared with the background curvature radius. The general formulas are applied to Friedmann-Robertson-Walker metrics of all spatial curvatures. The effect of new terms stemming from spatial curvature is potentially detectable in future gravitational wave measurements.
