description: In this paper we study properties of the Chow ring of rational homogeneous varieties of classical type, more concretely, effective zero divisors of low codimension, and a related invariant called effective good divisibility. This information is then used to study the question of (non)existence of nonconstant maps among these varieties, generalizing previous results for projective spaces and Grassmannians.

description: The high-frequency-peaked BL-Lacertae object \objectname{1ES 0806+524}, at redshift z=0.138, was observed in the very-high-energy (VHE) gamma-ray regime by VERITAS between November 2006 and April 2008. These data encompass the two-, and three-telescope commissioning phases, as well as observations with the full four-telescope array. \objectname{1ES 0806+524} is detected with a statistical significance of 6.3 standard deviations from 245 excess events. Little or no measurable variability on monthly time scales is found. The photon spectrum for the period November 2007 to April 2008 can be characterized by a power law with photon index $3.6 \pm 1.0_{\mathrm{stat}} \pm 0.3_{\mathrm{sys}}$ between $\sim$300 GeV and $\sim$700 GeV. The integral flux above 300 GeV is $(2.2\pm0.5_{\mathrm{stat}}\pm0.4_{\mathrm{sys}})\times10^{-12}\:\mathrm{cm}^{2}\:\mathrm{s}^{-1}$ which corresponds to 1.8% of the Crab Nebula flux. Non contemporaneous multiwavelength observations are combined with the VHE data to produce a broadband spectral energy distribution that can be reasonably described using a synchrotron-self Compton model.

description: In a recent work Grappin et al. [1] have shown that low- frequency movements can be transmitted from one footpoint to the other along a magnetic loop, thus mimicking a friction effect of the corona on the photosphere, and invalidating the line-tying approximation. We consider here successively the effect of high frequencies and turbulent damping on the process. We use a very simple atmospheric model which allows to study analytically the laminar case, and to study the turbulent case both using simple phenomenological arguments and a more sophisticated turbulence model [2]. We find that, except when turbulent damping is such that all turbulence is damped during loop traversal, coupling still occurs between distant footpoints, and moreover the coronal field induced by photospheric movements saturates at finite values.

Advancing seismic risk assessment methodologies for building structures
Creators: name: Kourehpaz, Pouria
Publisher: name: University of British Columbia
Year: 2024

description: This dissertation endeavors to advance seismic risk assessment methodologies for building structures through better characterization of the hazard and accounting for key sources of uncertainty within risk assessment models. The assessments are carried out at two scales, i.e., individual buildings and building portfolios, and focus on a range of modern reinforced concrete shear wall archetype buildings in Seattle, WA. At the individual building level, this dissertation incorporates the impacts of deep sedimentary basins into performance-based seismic assessments by quantifying earthquake-induced economic loss and downtime of buildings with different strengths, stiffness, and heights. These analyses can inform the engineering design community of the tradeoffs of adopting different design strategies when dealing with deep basin amplification. Considering the significant uncertainty in individual building risk assessment results, this dissertation conducts a probabilistic sensitivity analysis on loss and downtime estimates to highlight the significance of parameter choices (e.g., fragility functions) in risk outputs. At the building portfolio level, this dissertation employs advanced seismic fragility and machine learning-based models to enhance the accuracy of damage predictions and seismic losses. To this end, this dissertation develops multivariate building-taxonomy level fragility functions conditioned on advanced ground motion intensity measures (e.g., average spectral acceleration) to enhance the accuracy of seismic damage and loss estimates at a regional scale. The results indicate that the seismic loss prediction performance is significantly improved by employing multivariate fragility functions (even with only three variables) compared to univariate functions. Furthermore, this dissertation proposes a machine learning-based framework to predict a building’s anticipated earthquake-induced damage state by accounting for variability in building-to-building structural properties and ground motion shaking intensities. A separate predictive model is developed to conduct collapse risk assessments by integrating synthetic data samples into the original dataset. This framework shows great potential for enhancing building portfolio seismic risk assessments by leveraging building-specific input features and synthetic data samples for rare structural damage state instances. The outcomes of this dissertation can be used to enhance our understanding of the fundamental principles and procedures used in assessing seismic risk, which, in turn, can inform policy decisions to mitigate seismic risk and enhance resilience.
In search of progenitors for supernova-less GRBs 060505 and 060614: re-examination of their afterglows

description: GRB060505 and GRB060614 are nearby long-duration gamma-ray bursts (LGRBs) without accompanying supernovae (SNe) down to very strict limits. They thereby challenge the conventional LGRB-SN connection and naturally give rise to the question: are there other peculiar features in their afterglows which would help shed light on their progenitors? To answer this question, we combine new observational data with published data and investigate the multi-band temporal and spectral properties of the two afterglows. We find that both afterglows can be well interpreted within the framework of the jetted standard external shock wave model, and that the afterglow parameters for both bursts fall well within the range observed for other LGRBs. Hence, from the properties of the afterglows there is nothing to suggest that these bursts should have another progenitor than other LGRBs. Recently, Swift-discovered GRB080503 also has the spike + tail structure during its prompt gamma-ray emission seemingly similar to GRB060614. We analyse the prompt emission of this burst and find that this GRB is actually a hard-spike + hard-tail burst with a spectral lag of 0.8$\pm$0.4 s during its tail emission. Thus, the properties of the prompt emission of GRB060614 and GRB080503 are clearly different, motivating further thinking of GRB classification. Finally we note that, whereas the progenitor of the two SN-less bursts remains uncertain, the core-collapse origin for the SN-less bursts would be quite certain if a wind-like environment can be observationally established, e.g, from an optical decay faster than the X-ray decay in the afterglow's slow cooling phase.

description: We propose a scheme to dynamically create a supersolid state in an optical lattice, using an attractive mixture of mass-imbalanced bosons. Starting from a "molecular" quantum crystal, supersolidity is induced dynamically as an out-of-equilibrium state. When neighboring molecular wavefunctions overlap, both bosonic species simultaneously exhibit quasi-condensation and long-range solid order, which is stabilized by their mass imbalance. Supersolidity appears in a perfect one-dimensional crystal, without the requirement of doping. Our model can be realized in present experiments with bosonic mixtures that feature simple on-site interactions, clearing the path to the observation of supersolidity.

description: The study was focused on the concentration of Cadmium (Cd) and Chromium (Cr) contamination in vegetables that sold in local markets of Bangalore city. In this study we used the vegetables and green leafy vegetables such as cabbage, cucumber, cauliflower, green chilli, coriander, spinach. The accumulation of heavy metal was detected by using Atomic Absorption Spectrophotometry (AAS). The obtained results were showed that the concentration of Cadmium and Chromium were slightly exceeding the recommended maximum acceptable limits. The overall study concludes that the atmospheric deposition, untreated sewage water and poor unhygienic marketing systems were plays a main role in elevating the levels of Cadmium (Cd) and Chromium (Cr) in vegetables and green leafy vegetables.

description: Despite greatly improved observational methods, the presence of magnetic fields at cosmological scales and their role in the process of large-scale structure formation still remains unclear. In this paper we want to address the question how the presence of a hypothetical primordial magnetic field on large scales influences the cosmic structure formation in numerical simulations. As a tool for carrying out such simulations, we present our new numerical code AMIGA. It combines an N-body code with an Eulerian grid-based solver for the full set of MHD equations in order to conduct simulations of dark matter, baryons and magnetic fields in a self-consistent way in a fully cosmological setting. Our numerical scheme includes effective methodes to ensure proper capturing of shocks and highly supersonic flows and a divergence-free magnetic field. The high accuracy of the code is demonstrated by a number of numerical tests. We then present a series of cosmological MHD simulations and confirm that, in order to have a significant effect on the distribution of matter on large scales, the primordial magnetic field strength would have to be significantly higher than the current observational and theoretical constraints.

description: Harmonic functions $u:{\mathbb R}^n \to {\mathbb R}^m$ are equivalent to integral manifolds of an exterior differential system with independence condition $(M,{\mathcal I},ω)$. To this system one associates the space of conservation laws ${\mathcal C}$. They provide necessary conditions for $g:{\mathbb S}^{n-1} \to M$ to be the boundary of an integral submanifold. We show that in a local sense these conditions are also sufficient to guarantee the existence of an integral manifold with boundary $g({\mathbb S}^{n-1})$. The proof uses standard linear elliptic theory to produce an integral manifold $G:D^n \to M$ and the completeness of the space of conservation laws to show that this candidate has $g({\mathbb S}^{n-1})$ as its boundary. As a corollary we obtain a new elementary proof of the characterization of boundaries of holomorphic disks in ${\mathbb C}^m$ in the local case.
title: Examining the association between cycling infrastructure and cycling: baseline results from INTERACT Victoria
Creators: name: Tobin, Melissa
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The majority of Canadians are not meeting physical activity guidelines. Implementing infrastructure that supports active transportation is an important intervention to increase population physical activity levels. The INTErventions, Research and Action in Cities Team (INTERACT), has the goal to advance research on the design of healthy and sustainable cities for all. My study is a sub-project of INTERACT and has three main objectives. The first objective is to determine whether participants support the All Ages and Abilities (AAA) Cycling Network. The second objective is to examine the association between exposure to the Pandora protected cycle track and physical activity levels and the third objective is to determine if there are gender differences in overall levels of physical activity. I hypothesized that participants would support the AAA Cycling Network and exposure to the Pandora protected cycle track would be associated with greater overall physical activity levels of residents who cycle at least once a month in Victoria. I also hypothesized that women would have lower levels of physical activity when compared to men. INTERACT recruited 281 people who completed online surveys; 149 of whom wore a Sensedoc (an accelerometer and global positioning system (GPS), for ten days to collect physical activity and spatial location data). Data collection took place from May 19, 2017, to November 30, 2017. I calculated exposure to the Pandora protected cycle track using daily path mobility, which measures the ratio of the number of GPS points within 200 metres of the Pandora protected cycle track compared to the participants number of total GPS points. Overall, participants supported the AAA Cycling Network and showed a preference for off-road paths and separated cycling infrastructure. This preference was especially true for women, who also reported much less physical activity per week than men. Regression analysis showed that there were associations between exposure to the Pandora protected cycle track and both self-report and accelerometer-based physical activity, but only after a certain threshold of exposure. The implementation of the AAA Cycling Network with an emphasis on protected cycling infrastructure may increase cycling frequency and physical activity levels in the City of Victoria.

Year: 2021

description: This study investigates the existing diurnal as well as night time surface ozone concentration trend over Delhi between 1990 and 2012. Secondary data obtained from the National Data Centre (NDC) of the India Meteorological Department (IMD) was analysed to assess the trend in the surface and night-time ozone concentration. This was further used to forecast the variation in the night-time ozone concentration over the city till 2025. A significantly increasing trend of the night-time ozone concentration was observed between 1990 and 2012 evidenced by a +0.158 value of the Mann Kendall test. Moreover, the forecasting of the variations conducted using the Autoregressive Integrated Moving Average (ARIMA) model revealed that the concentration of night-time ozone is expected to increase between the period of 2013 and 2025 if the current trend continues. This is the first study to conduct a trend analysis of night-time ozone concentration for a duration of three decades in the NCT of Delhi. Considering the negative impacts of elevated levels of ozone on the health status of individuals, agricultural productivity and air quality of the city, the present study highlights that it is imperative to take concentrated actions to curb the release of anthropogenic precursors of surface ozone.

Design of gravity-load frames for seismic deformation demands in highrise concrete buildings with shear walls in Canada
Creators: name: Sainz Albanez, Guillermo
Publisher: name: University of British Columbia
Year: 2024

description: A building can be divided into two main components: the seismic-force resisting system (SFRS), responsible for withstanding seismic forces, and the remaining structure, often referred to as the gravity-load resisting frame (GLRF). Although the GLRF is not designed to resist seismic forces directly, it must be designed to accommodate the seismic deformation demands of the entire structure. The Canadian building code, specifically CSA A23.3 Clause 21.11, outlines requirements for designing the GLRF. These requirements are relatively new and have not seen widespread adoption in engineering practice. Design engineers have faced challenges in efficiently performing the required calculations. This thesis explores various methods to apply the specified interstorey drift envelope from CSA A23.3 to shear wall buildings' GLRF. It offers practical recommendations for using the computer program ETABS to impose the necessary lateral displacements. The thesis includes a comprehensive building design case study that demonstrates the proposed procedure and examines the design criteria for the GLRF in typical shear wall buildings, exploring various GLRF configurations. Additionally, the 2020 edition of the National Building Code of Canada (NBCC) introduces new requirements for designing the GLRF of buildings exceeding 30 metres in height in seismic category SC4 (regions of high seismicity, such as the lower mainland of BC). A case study is conducted to assess the implications of these new requirements, which have been adopted in BC in March 2024.

description: This thesis utilizes a critical discourse analysis methodology to explore the experiences of members of a First Nations community in Labrador with mental health and addictions care systems. In particular, an understanding of how colonization has impacted the mental health of this community and the ways in which colonization is or is not considered within the treatment provided within mental health and addictions services is explored from the perspective of community members. In addition, the thesis includes a review and guide for white social work researchers to engage in politically-informed research with Indigenous communities in a way that is respectful and ethical. This includes an analysis of the role of academia, the role of research and the role of social work in preserving and reinforcing colonialist ideals, as well as the ways in which research with Indigenous communities may be decolonized in order to be more ethical, respectful, and responsible.

description: We present the star formation history (SFH) and its variations with galactocentric distance for the Local Group dwarf galaxy of Phoenix. Color-magnitude diagram was obtained from WFPC2@HST reaching the oldest main sequence turnoffs. The IAC-star and IAC-pop codes and the MinnIAC suite have been used to obtain the star formation rate as a function of time, metallicity, and radius. We find that Phoenix has had ongoing but gradually decreasing star formation over nearly a Hubble time. The highest level of star formation occurred from the formation of the galaxy till 10.5 Gyr ago, when 50% of the total star formation had already taken place. From that moment, star formation continues at a significant level until 6 Gyr ago, and at a very low level till the present time. The chemical enrichment law shows a trend of slowly increasing metallicity as a function of time till 8--6 Gyr ago, when Z starts to increase steeply to the current value. Young stars are found in the inner region of the galaxy only, but intermediate-age and old stars can be found at all galactocentric distances. This study shows that star formation started at all galactocentric distances in Phoenix at an early epoch. Our results are compatible with a scenario in which the star formation region envelope slowly shrinks as time goes on, possibly as a natural result of pressure support reduction as gas supply diminishes. As a consequence, star formation stopped first in outer regions and the scale-length of the stellar mass density distribution decreased with time. No traces of a true, old halo are apparent in Phoenix either in its stellar age distribution or in the stellar mass density distribution, at least out to 0.5 kpc (about 2.5 scale-lengths) from the center.

However, the implication of dysregulated FFA on semen quality and the involvement of Sertoli cells remain unclear. In the present study, we report obesity decreased Sertoli cell viability through dysregulated FFAs. We observed an increased rate of apoptosis in Sertoli cells, accompanied with elevated FFA levels, in the testes of obese mice that were provided a high-fat diet (HFD). Moreover, the levels of reactive oxygen species were elevated. Furthermore, we demonstrated by in vitro assays that saturated palmitic acid (PA), which is the most common saturated FFA in plasma, led to decreased cell viability of TM4 Sertoli cells in a time- and dose-dependent manner. A similar finding was noted in primary mouse Sertoli cells. In contrast to saturated FFA, omega-3 (ω-3) polyunsaturated fatty acids (PUFAs) protected Sertoli cells from PA-induced lipotoxicity at the physiologically relevant levels. These results indicated that the lipotoxicity of saturated fatty acids might be the cause of obesity-induced Sertoli cell apoptosis, which leads to decreased semen quality. In addition, ω-3 PUFAs could be classified as protective FFAs.

description: We present a new optoelectronic architecture intended for chaotic optical intensity generation. The principle relies on an electro-optic non-linear delay dynamics, which non linearity is performed by a 4-waves integrated optics interferometer involving 2 independent electro-optic modulation inputs. The setup allows both to have an ultra-fast dynamics up to several GHz frequencies, and potentially high dimensional chaos intended for encryption of optical data at the physical layer. We have built a mathematical model of the system and analyzed a number of its possible solutions: stable steady states, periodic and chaotic regimes. The experimental observations allowed to validate the dynamical model, through good qualitative agreements with the numerical simulations.

description: We begin an exploration of the physics associated with the general CP-conserving MSSM with Minimal Flavor Violation, the pMSSM. The 19 soft SUSY breaking parameters in this scenario are chosen so as to satisfy all existing experimental and theoretical constraints assuming that the WIMP is a conventional thermal relic, ie, the lightest neutralino. We scan this parameter space twice using both flat and log priors for the soft SUSY breaking mass parameters and compare the results which yield similar conclusions. Detailed constraints from both LEP and the Tevatron searches play a particularly important role in obtaining our final model samples. We find that the pMSSM leads to a much broader set of predictions for the properties of the SUSY partners as well as for a number of experimental observables than those found in any of the conventional SUSY breaking scenarios such as mSUGRA. This set of models can easily lead to atypical expectations for SUSY signals at the LHC.

title: Phosphorus dynamics in boreal podzols converted from forest to agriculture
Creators: name: Kedir, Amana Jemal
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Phosphorus (P) is a non-renewable and vital element for all life and the second most yield-limiting nutrient next to nitrogen in agriculture. The global and regional soil P pools, fluxes and the governing biogeochemistry vary with soil, vegetation, and management types. Limited understanding of the dynamics of P fluxes and pools in the Newfoundland (Nfld) natural and agricultural Podzols hampers decisions on best management options. To fill this knowledge gap, I: (a) assessed the levels and status of P in Nfld farm soils and their relationship with the recommended fertilizer rates across locations and managements; (b) evaluated the utility of ten P-extraction and analysis tests (P-test) for P extractability in natural grassland, as well as forested and agricultural soils; (c) determined P adsorption isotherms for forested and agricultural soil horizons; (d) investigated the P adsorption capacity of long-term managed soils; and (e) carried out a greenhouse trial to evaluate the plant uptake of P from soil layers relevant to soils converted from forested to agricultural use. The provincial Mehlich-3 P-test confirmed the relationship between measured P and the recommended P rates, but also suggests possible overfertilization. Soil P-test measurements varied with management status and were affected by the soil organic matter (SOM), Al, Fe, and soil depth or horizon. Citric acid extracted significantly more P for all tested soil conditions except for newly converted soils. Phosphorus adsorption capacity varied by soil horizon, depth, and management. Phosphorus availability and uptake in recently converted soils from forested to agriculture varied with soil depth and P sources. Given the variability in results and the possibility for a mismatch between P application and P uptake for soils, differentially across a range of conversion ages and managements, it is critical that further agronomic work focuses on the detailed understanding of P species and the effect of management on the P biogeochemistry, with a focus on the role of SOM and mineral contents. It is recommended that targeted calibration of P-test and recommendations be carried out to cover all sources of variability in soils that have undergone conversion to confirm the relationship between P sources, extractability, and uptake for different conversion and management states.

Basin amplification effects and seismic performance of non-ductile reinforced concrete shear wall buildings during subduction earthquakes
Creators: name: Kakoty, Preetish

Year: 2024

description: Southwestern Canada is exposed to the 1000-kilometer-long Cascadia Subduction Zone (CSZ) off Vancouver Island which can produce large magnitude earthquakes. The last known CSZ earthquake occurred in 1700, leaving a gap in the understanding of the expected shaking intensity associated with such events. Metro Vancouver's tall buildings, primarily comprised of reinforced concrete shear wall (RCSW) structures, are vulnerable to these earthquakes because the region lies above the Georgia sedimentary basin, which can amplify ground motion shaking, particularly in the medium-to-long period range and is not accounted for in current building codes. Tall buildings constructed prior to the 1980s are of special concern because they predate modern seismic codes and are clustered in densely populated areas, raising concerns about the risks to life, property, and recovery from large earthquakes. This dissertation addresses these gaps by quantifying ground motion amplification from the Georgia sedimentary basin during CSZ earthquakes and assessing seismic performance of older tall RCSW buildings. Physics-based simulations for 30 M9 CSZ earthquakes, considering basin effects, are used to quantify site-specific basin amplification factors. A framework is proposed to integrate these factors into uniform hazard spectra (UHS) calculations to account for basin amplification effects. The results indicate strong correlation between spectral acceleration basin amplification and basin depth, with the average amplification factor at the deepest basin site is 2.24 for a 2-second period, resulting in 58% increase in UHS at the same period. For older tall RCSW buildings, collapse risk is assessed via nonlinear response history analysis of 3D models for 25 archetypes which are informed from a detailed inventory of such buildings. These estimates use hazard estimates from Canada's national seismic hazard model, that does not consider basin effects, and a "hybrid" model accounting for basin amplification. The 50-year collapse probability ranges from 6% to 40%, which increases by 33% on average with the "hybrid" model. The dissertation also includes seismic performance assessment under a M9 CSZ scenario to estimate economic losses and recovery times. The mean loss ratio for 25 archetype buildings ranges from 54% to 82%, exceeding the ~40% threshold for likely demolition, suggesting elevated levels of risk.

description: The possible role of a first order QCD phase transition at nonvanishing quark chemical potential and temperature for cold neutron stars and for supernovae is delineated. For cold neutron stars, we use the NJL model with nonvanishing color superconducting pairing gaps, which describes the phase transition to the 2SC and the CFL quark matter phases at high baryon densities. We demonstrate that these two phase transitions can both be present in the core of neutron stars and that they lead to the appearance of a third family of solution for compact stars. In particular, a core of CFL quark matter can be present in stable compact star configurations when slightly adjusting the vacuum pressure to the onset of the chiral phase transition from the hadronic model to the NJL model. We show that a strong first order phase transition can have strong impact on the dynamics of core collapse supernovae. If the QCD phase transition sets in shortly after the first bounce, a second outgoing shock wave can be generated which leads to an explosion. The presence of the QCD phase transition can be read off from the neutrino and antineutrino signal of the supernova.
