description: We present a very simple 4th-generation (4G) model with an Abelian gauge interaction under which only the 4G fermions have nonzero charge. The U(1) gauge symmetry can have a Z_2 residual discrete symmetry (4G-parity), which can stabilize the lightest 4G particle (L4P). When the 4G neutrino is the L4P, it would be a neutral and stable particle and the other 4G fermions would decay into the L4P leaving the trace of missing energy plus the standard model fermions. Because of the new symmetry, the 4G particle creation and decay modes are different from those of the sequential 4G model, and the 4G particles can be appreciably lighter than typical experimental bounds.

description: Centrioles are organelles in eukaryotic cells with essential functions including organizing the microtubule cytoskeleton and orchestrating mitotic spindle formation. Proper control of centriole number is crucial, as deviations have deleterious consequences. Centriole duplication in Caenorhabditis elegans is initiated in S-phase by the ZYG-1 kinase. Disruption of zyg-1 results in embryonic arrest, as centrioles fail to duplicate. Many negative regulators of centriole biogenesis are suppressors of zyg-1 and can rescue centriole biogenesis and viability in worms carrying a hypomorphic zyg-1 allele. In this thesis, I characterize the role of otub-3, a novel suppressor of zyg-1 identified in a high-throughput genetic screen of zyg-1 in the Tarailo-Graovac lab. I demonstrate that loss of otub-3 rescues viability and centriole duplication in a zyg-1 mutant background without causing centriole amplification in a wildtype background. otub-3 encodes a functional deubiquitinase enzyme and disrupting the catalytic function of OTUB-3 is sufficient to suppress zyg-1. Additionally, loss of otub-3 suppresses spd-2 and zyg-1, but not sas-6, demonstrating genetic relationships with early regulators of centriole biogenesis. A deletion mutant for otub-3 displays normal mitotic timing, suggesting that the interaction between otub-3 and the centriole is independent of the APC/C pathway. OTUB-3 is cytoplasmic and excluded from the nucleus, indicating a potential role in post-translational regulation of centriole regulators. Loss of otub-3 reduces brood size but does not cause embryonic lethality, indicating otub-3 is non-essential and implicated in fertility. Immunoprecipitation followed by mass-spectrometry revealed a physical interaction between OTUB-3 and KIN-3, a known negative regulator of centriole biogenesis. Genetic experiments revealed a genetic interaction between otub-3 and kin-3 as well, positioning otub-3 within a regulatory network functioning to regulate C. elegans centriole biogenesis. This study establishes OTUB-3 as the first deubiquitinase implicated in centriole biogenesis in C. elegans. In addition, this work provides insight into the etiology of human disease. OTUD6B, the human ortholog of otub-3, is linked via an unknown mechanism with primary microcephaly, a genetic disorder commonly caused by centriolar defects. This thesis is the first work to demonstrate a link between an ortholog of OTUD6B and centriole biogenesis, giving a possible mechanism for OTUD6B-linked microcephaly.

Futterprotein

description: Die Schweiz importiert über 80 % des Rohproteins von Futtermitteln für landwirtschaftliche Nutztiere und die Aquakultur. Auch in der Biolandwirtschaft. Eine mögliche Strategie zur Deckung der Proteinversorgung ist daher die Entwicklung von Futtermitteln auf Insektenbasis. Damit liessen sich in der Schweiz anfallende Reststoffe aus der Lebensmittelproduktion weiterverarbeiten und die Lebensmittelverschwendung reduzieren. Knapp 60 % der gesamten Lebensmittelabfälle wären für die Verfütterung an Nutztiere, zu denen auch die Futterinsekten gezählt werden, geeignet. Dieser Teil der Lebensmittelverluste kommt hauptsächlich aus der Verarbeitung (38 %), direkt aus der Landwirtschaft (13 %) oder dem Handel (8 %). Die Zucht von Insektenlarven zur Futtermittelproduktion kann also dazu beitragen verschiedene Probleme zu lösen und gleichzeitig Synergien schaffen: Durch die Verfütterung an Insekten lassen sich verschwendete Lebensmittel dem Gesamtkreislauf wieder zuführen. Grosse Mengen an Food waste würden somit im Nährstoffkreislauf erhalten bleiben. Aus den gezüchteten Insekten lassen sich hochwertiges Rohprotein, Fette oder auch lebendiges Ergänzungsfutter generieren. Damit liessen sich hohe Importe und weite Transporte vermeiden und der Land- und Wasserverbrauch sowie die Überfischung reduzieren. Durch den Aufbau effizienter und nachhaltiger Insekten-Produktionsstätten liessen sich die Klimabilanz und der Ressourcenhaushalt der Schweizer Landwirtschaft verbessern.
Distributions and interactions of insect herbivores as influences on host plant density and performance
Creators: name: Stephens, Andrea Elizabeth Alice
Publisher: name: University of British Columbia
Year: 2012

description: Biological control programmes to reduce the density of invasive weeds often introduce multiple species of insect herbivores before reductions of the weed population occur. The factors leading to successful control need to be identified to improve success rates and reduce the number of insect introductions. These factors may be traits of the biocontrol agent-plant system, or may be external influences such as the presence of other biocontrol agents or environmental conditions. A characteristic that varies among insect herbivores is their distribution among plants. I developed a simulation model that demonstrates how insects distributed in direct proportion to plant density cause the fastest rate of host plant population decline. This agrees with observations of a successful species, Larinus minutus, compared to an unsuccessful one, Urophora affinis, in the diffuse knapweed (Centaurea diffusa) biocontrol system. Using the successful biocontrol agent, L. minutus, I experimentally tested whether adult as well as larval feeding increased control of diffuse knapweed. My results suggest that agents with both adult and larval feeding can control plants in a wider range of environments. With a meta-analysis I tested if the presence of other biocontrol agents alters the relationship that a natural enemy has with the host-plant, and showed that the reduction in plant performance caused by one natural enemy is, on average, independent of the second. I also show that the occurrence of non-independent interactions between natural enemies can be predicted by a small range of enemy or plant attributes. (direct interactions and attack to reproductive plant parts). My experiment using the root herbivore, Cyphocleonus achates and the aboveground herbivore L. minutus showed that interactions between the two species can increase the reduction in seed produced by the plant, potentially enhancing biocontrol. My thesis demonstrates that attributes of the biocontrol agents themselves and their interactions with traits of other agents can alter plant performance or plant population decline. Research into attributes associated with successful, and unsuccessful, biocontrol will improve success rates.

description: The human auditory cortex simultaneously processes speech and determines the location of a speaker in space. Neuroimaging studies in humans have implicated core auditory areas in processing the spectrotemporal and the spatial content of sound; however, how these features are represented together is unclear. We recorded directly from human subjects implanted bilaterally with depth electrodes in core auditory areas as they listened to speech from different directions. We found local and joint selectivity to spatial and spectrotemporal speech features, where the spatial and spectrotemporal features are organized independently of each other. This representation enables successful decoding of both spatial and phonetic information. Furthermore, we found that the location of the speaker does not change the spectrotemporal tuning of the electrodes but, rather, modulates their mean response level. Our findings contribute to defining the functional organization of responses in the human auditory cortex, with implications for more accurate neurophysiological models of speech processing.

description: We analyze the Majorana equation in the limit where the particle is at rest. We show that several counterintuitive features, absent in the rest limit of the Dirac equation, do appear. Among them, Dirac-like positive energy solutions that turn into negative energy ones by free evolution, or nonstandard oscillations and interference between real and imaginary spinor components for complex solutions. We also study the ultrarelativistic limit, showing that the Majorana and Dirac equations mutually converge. Furthermore, we propose a physical implementation in trapped ions.

description: We consider field-theoretic models, one consisting purely of scalars, the other also involving fermions, that couple to a set of constant background coupling coefficients transforming as a symmetric observer Lorentz two-tensor. We show that the exact propagators can be cast in the form of a Källén-Lehmann representation. We work out the resulting form of the Feynman propagators and the equal-time field commutators, and derive sum rules for the spectral density functions.

description: Industrial Control Systems (ICS) serve as indispensable components across diverse human industries, encompassing vital sectors like Oil and Gas companies, Power Grids, and Transportation. The evolution of technology has witnessed a paradigm shift in communication within ICS, transitioning from traditional systems to wireless communication for swift monitoring and control. However, this technological advancement has simultaneously exposed ICS to the online world, amplifying the susceptibility to cyber attacks and threats. Given the pivotal role of ICS in human life, establishing a robust framework to ensure the security and privacy of these systems has become an imperative. The repercussions of failing to secure ICS extend beyond data breaches, potentially endangering human lives and the environment. This thesis meticulously addresses the omnipresent threat of cyber-attacks on critical infrastructures, centering on the development of an advanced security-privacy framework tailored for ICS. The framework is designed to adeptly detect Generative Adversarial Attacks (GAAs), facilitate explainable attack attribution, and uphold privacy through the implementation of Federated Learning (FL). Innovative solutions presented in this thesis transcend traditional cybersecurity measures, providing comprehensive enhancements for critical infrastructures that include power grids and industrial systems. Beyond merely fortifying model robustness against adversarial attacks, the proposed frameworks are characterized by a steadfast commitment to prioritizing privacy. Moreover, it furnishes effective tools for attack attribution and anomaly prediction within dynamic and complex environments.
Beyond perfection: Reclaiming death in and for education

Year: 2021

description: In associating death with education, this paper explores how the death register, and in particular the denial of death, is reflected in the treatment of contemporary education, aiming to construct the future as an object of knowledge for providing certainty and authority. Through a reading of Gert Biesta’s theoretical considerations, I discuss how educational systems scientifically explained and measured are created to be fixed (or healed), in pursuit of a type of education as a social apparatus to enable or reach for a perfect future. I argue however, that such medical-like treatment runs the risk of negating the complex, relational, and fragile qualities of educational life. Into the second part, I offer new perspectives on death and loss to be imagined as occasions for emancipation within pedagogical encounters between subjects; giving space for unpredictability, riskiness, ambiguity, and messiness to occur. My overall contention is that when desires of immortality overpower an appreciation of the finitude and fragility of all things, a part of life is denied. When education is not confronted with important and challenging questions on its purposes, this should be considered dangerous or even lethal for a safe system to thrive; we miss out on what is educational in education, we miss an encounter with reality.

description: During the RV POSEIDON research cruise, POS531, from Las Palmas (Canary Islands) to Mindelo (Cape Verde), we studied organic matter transport in the Cape Blanc upwelling region. Cape Blanc upwelling is one of the coastal upwelling regimes of the Eastern Boundary Current Systems (EBUEs), which are the most productive ocean areas and key players in the global carbon cycle and climate change. Pelagic primary production drives the biological pump which, in coastal upwelling regions, is largely controlled by the sinking behaviour and lateral transport of marine snow aggregates and faecal pellets. We still lack a quantitative understanding about the role that zooplankton grazing, sediment processes, and lateral transport play in the transformation and export of particulate organic matter. Further gaps in knowledge exist about the distribution of particles, their size and density and the particle sinking velocities of various biogenic and lithogenic components. Even less is known about what happens when particles reach the sandy seafloor and the role that benthic primary production plays in shallow shelf systems. The sandy seabed is regularly reworked and resuspended and therefore biogeochemical processes in the sediment likely play an important role in nutrient and organic matter transformation. To study how the sandy shelf area is connected to open ocean carbon export and carbon sequestration, we deployed free-drifting sediment traps to study short term variability in mass fluxes and the decay and transformation of large, organic-rich marine snow particles. In addition, the water column was sampled and studied using in situ-pumps, Marine Snow Catchers, particle cameras, and vertical multi-net hauls. To link the pelagic processes with the benthic remineralization and production, we deployed benthic boundary layer samplers and benthic lander systems. This allowed us to study the physical environment near the seabed and elucidate its effects on the biogeochemistry of the sediment, which was quantified through in situ and on-board laboratory rate measurements. The major aim of the research cruise was to better quantify the carbon and nitrogen cycling in the sandy shelf region and to quantify the impact from this cycling on lateral transport to the open ocean.

description: This thesis explores the intricate and complex aspects of human experience, focusing on the interplay between artistic expression and the process of grappling with loss. It examines how art can serve as a transformative and therapeutic tool for individuals collectively experiencing grief. Central to this exploration is an installation designed as a dining room, where the audience, like guests, can sit at the table, flip through drawings, and engage in shared experiences of loss. This interactive setup, termed "sitting," invites guests to contribute their own stories of grief in a memory book, fostering a shared space of empathy and connection. Strict ethical standards are upheld by asking contributors to remain anonymous, not sharing personal details that might identify them, and destroying the memory book when the MFA exhibition ends. Each drawing in this collection acts as a personal diary, capturing emotions and experiences, and creating a collective narrative. The research methods employed are qualitative and introspective, focusing on personal experiences as the primary source of knowledge. This thesis examines the personal therapeutic process through art and contributes to a broader cultural dialogue about resilience, vulnerability, and the human condition. By breaking the silence surrounding grief, this project transforms private suffering into a public declaration of resilience and hope.
Negative Quasi-Probability as a Resource for Quantum Computation

description: A central problem in quantum information is to determine the minimal physical resources that are required for quantum computational speedup and, in particular, for fault-tolerant quantum computation. We establish a remarkable connection between the potential for quantum speed-up and the onset of negative values in a distinguished quasi-probability representation, a discrete analog of the Wigner function for quantum systems of odd dimension. This connection allows us to resolve an open question on the existence of bound states for magic-state distillation: we prove that there exist mixed states outside the convex hull of stabilizer states that cannot be distilled to non-stabilizer target states using stabilizer operations. We also provide an efficient simulation protocol for Clifford circuits that extends to a large class of mixed states, including bound universal states.
description: 15 pages v4: This is a major revision. In particular, we have added a new section detailing an explicit extension of the Gottesman-Knill simulation protocol to deal with positively represented states and measurement (even when these are non-stabilizer). This paper also includes significant elaboration on the two main results of the previous version

description: The focus of this work is the analysis of the thermal impact and its depth effect in different grinding processes. The investigated processes cover different kinematics and thus broad ranges of the relative speeds and the intensities of the moving heat source regarding the ground surface. A uniform lower process limit characterizing the onset of grinding burn for the different kinematics is identified by means of the specific grinding power and the contact time. The experimental results together with the theoretical considerations of peak temperatures lead to the conclusion that the process specific range of the contact time is mainly responsible for the thermal depth effect. The results enable the targeted exceeding of the critical process limit in roughing and the subsequent correction by finishing.
Caloric curve for nuclear liquid-gas phase transition in relativistic mean-field hadronic model

description: The main thermodynamical properties of the first order phase transition of the relativistic mean-field (RMF) hadronic model were explored in the isobaric, the canonical and the grand canonical ensembles on the basis of the method of the thermodynamical potentials and their first derivatives. It was proved that the first order phase transition of the RMF model is the liquid-gas type one associated with the Gibbs free energy $G$. The thermodynamical potential $G$ is the piecewise smooth function and its first order partial derivatives with respect to variables of state are the piecewise continuous functions. We have found that the energy in the caloric curve is discontinuous in the isobaric and the grand canonical ensembles at fixed values of the pressure and the chemical potential, respectively, and it is continuous, i.e. it has no plateau, in the canonical and microcanonical ensembles at fixed values of baryon density, while the baryon density in the isotherms is discontinuous in the isobaric and the canonical ensembles at fixed values of the temperature. The general criterion for the nuclear liquid-gas phase transition in the canonical ensemble was identified.

description: Recently, numerous rare de novo mutations have been identified in patients diagnosed with autism spectrum disorders (ASD). However, despite the predicted loss-of-function nature of some of these de novo mutations, the affected individuals are heterozygous carriers, which would suggest that most of these candidate genes are haploinsufficient and/or lead to expression of dominant-negative forms of the protein. Here, we tested this hypothesis with the candidate ASD gene Nuak1 that we previously identified for its role in the development of cortical connectivity. We report that Nuak1 is haploinsufficient in mice with regard to its function in cortical development. Furthermore Nuak1+/- mice show a combination of abnormal behavioral traits ranging from defective spatial memory consolidation, defects in social novelty (but not social preference) and abnormal sensorimotor gating. Overall, our results demonstrate that Nuak1 haploinsufficiency leads to defects in the development of cortical connectivity and a complex array of behavorial deficits.

description: In the research concept of Process Signatures machining induced changes of surface and sub-surface material properties are considered as material modifications caused by the physical conditions the material is exposed to during the process. This paper presents a newly developed multilayer source stress model to analytically describe the material modifications caused by the machining process in multiple passes. The analytical model that needs measured shape deviations as input is validated via finite element simulations. The approach incorporates the effects of machining induced source stresses and the contribution of residual stresses present in the workpiece before machining. Results from milling experiments show a pronounced correlation between the identified workpiece material modifications and the width of cut.

description: This research-creation is a photographic-videographic approach to the concept of fatherhood. It is based on my experience as a father of two children aged ten and thirteen since our arrival as a family in Canada in 2022. It is a panoramic view of a time of change where, facing the challenges of fatherhood towards growing children, I begin a search in my years as a son with a father (who passed away in 2018) who marked and still marks my becoming in the world as well as my work as a father. His memory and his way of exercising fatherhood influence mine, which I feel as a middle ground between what I lived in my childhood-adolescence and the present-future of my children. If being a father implies conflicts and disagreements, how do childhood memories and reminiscences influence my practice as a father and the models I try to transmit to my children? My base of work is the world of family photography and filmmaking. Belonging to the environment that is photographed and filmed is a very powerful artistic-reflexive practice that opens thought to what is common to us as humans: the constant presence of belonging and separation in our work as parents.
Image-charge induced localization of molecular orbitals at metal-molecule interfaces: Self-consistent GW calculations

description: Quasiparticle (QP) wave functions, also known as Dyson orbitals, extend the concept of single-particle states to interacting electron systems. Here we employ many-body perturbation theory in the GW approximation to calculate the QP wave functions for a semi-empirical model describing a $π$-conjugated molecular wire in contact with a metal surface. We find that image charge effects pull the frontier molecular orbitals toward the metal surface while orbitals with higher or lower energy are pushed away. This affects both the size of the energetic image charge shifts and the coupling of the individual orbitals to the metal substrate. Full diagonalization of the QP equation and, to some extent, self-consistency in the GW self-energy, is important to describe the effect which is not captured by standard density functional theory or Hartree-Fock. These results should be important for the understanding and theoretical modeling of electron transport across metal-molecule interfaces.

description: The urothelium is an epithelia barrier lined by a luminal layer of binucleated, octoploid, superficial cells. Superficial cells are critical for production and transport of uroplakins, a family of proteins that assemble into a waterproof crystalline plaque that helps protect against infection and toxic substances. Adult urothelium is nearly quiescent, but rapidly regenerates in response to injury. Yet the mechanism by which binucleated, polyploid, superficial cells are produced remains unclear. Here, we show that superficial cells are likely to be derived from a population of binucleated intermediate cells, which are produced from mononucleated intermediate cells via incomplete cytokinesis. We show that binucleated intermediate and superficial cells increase DNA content via endoreplication, passing through S phase without entering mitosis. The urothelium can be permanently damaged by repetitive or chronic injury or disease. Identification of the mechanism by which superficial cells are produced may be important for developing strategies for urothelial repair.

description: Online event hosting platforms, such as Zoom Meetings and Twitch Streams, have revolutionized the way we socialize with one another. These platforms offer a rich set of interactive features such as live chat and gestures, enabling dynamic and engaging social events. In public events, however, participants are not well-known entities originating from the same institution, and thus traditional access control fails to provide means for maintaining order without disrupting interactivity. Zoombombing and cyberbullying in Twitch streams are symptoms of this dilemma. The design of the aforementioned event hosting systems thus resort to social control mechanisms that allow moderators to monitor the social interactions of the participants and respond to disorderly behavior in real time. The designer of an event hosting system needs to make sure that social control mechanisms preserve interactivity expectations. In this work, we introduce HIPE (Highly Interactive Public Event), a framework for modelling social control mechanisms, articulating interactivity expectations, as well as verifying if social control interferes with interactivity. We catalogued four classes of social control mechanisms that can be reused in the design of event hosting systems, namely sanction, remedy, containment, and retaliation. Additionally, we formulated a 2-safety hyperproperty characterization of interactivity called (a, p)-interactivity and a stricter version, strong (a, p)-interactivity, to express the degree of interactivity expected of an event hosting system. Furthermore, we designed model checking algorithms for verifying both (a, p)-interactivity and strong (a, p)-interactivity. An empirical case study has been conducted to illustrate the interplay between social control and interactivity, as well as to evaluate the performance of our model checking algorithm. To the best of our knowledge this is the first work to formally study the balancing of social control and interactivity in anonymous public events.

description: A re-evaluation of time-averaged accretion rates at DBZ-type white dwarfs points to historical, time-averaged rates significantly higher than the currently observed episodes at their DAZ counterparts. The difference between the ongoing, instantaneous accretion rates witnessed at DAZ white dwarfs, which often exceed 1e8 g/s, and those inferred over the past 1e5-1e6 yr for the DBZ stars can be a few orders of magnitude, and therefore must result from high-rate episodes of tens to hundreds of years so they remain undetected to date. This paper explores the likelihood that such brief, intense accretion episodes of gas-phase material can account for existing data. For reasonable assumptions about the circumstellar gas, accretion rates approaching or exceeding 1e15 g/s are possible, similar to rates observed in quiescent cataclysmic variables, and potentially detectable with future x-ray missions or wide-field monitoring facilities. Gaseous debris that is prone to such rapid accretion may be abundant immediately following a tidal disruption event via collisions and sublimation, or if additional bodies impinge upon an extant disk. Particulate disk matter accretes at or near the Poynting-Robertson drag rate for long periods between gas-producing events, consistent with rates inferred for dusty DAZ white dwarfs. In this picture, warm DAZ stars without infrared excesses have rates consistent with accretion from particulate disks that remain undetected. This overall picture has implications for quasi-steady state models of accretion and the derived chemical composition of asteroidal debris in DBZ white dwarfs.

description: Maintaining balance after an external perturbation requires modification of ongoing motor plans and the selection of contextually appropriate muscle activation patterns that respect body and limb position. We have used the vestibular system to generate sensory-evoked transitions in motor programming. In the face of a rapid balance perturbation, the lateral vestibular nucleus (LVN) generates exclusive extensor muscle activation and selective early extension of the hindlimb, followed by the co-activation of extensor and flexor muscle groups. The temporal separation in EMG response to balance perturbation reflects two distinct cell types within the LVN that generate different phases of this motor program. Initially, an LVNextensor population directs an extension movement that reflects connections with extensor, but not flexor, motor neurons. A distinct LVNco-activation population initiates muscle co-activation via the pontine reticular nucleus. Thus, distinct circuits within the LVN generate different elements of a motor program involved in the maintenance of balance.
title: New Approaches to Investigate the Oxygen Cost of Exercise Applied to Human Performance

description: During exercise, there is a tight control between anaerobic and aerobic energy sources to meet the demand in adenosine triphosphate (ATP) for energy provision. Oxidative phosphorylation provides ATP via aerobic energy sources assuming an adequate supply of oxygen (O2) to the active tissues is provided. When the intensity of exercise is within the heavy domain (i.e., above the gas exchange threshold (GET)), there is an increased O2 cost per unit of work (i.e., V̇O2 gain; G) which has commonly been attributed to the development of the oxygen uptake slow component (V̇O2SC), in connection to a lower exercise efficiency. Therefore, finding new strategies to (i) decrease the O2 cost of exercise, (ii) explore the dynamics of V̇O2, and (iii) enhance exercise performance and improve cardiovascular fitness assessment is paramount in the field of exercise physiology. The general purpose of this thesis was to contribute to addressing the issues highlighted above. By implementing different exercise protocols, we found that: (i) approaching a target heavy-intensity constant-work rate (WR) gradually via a progressive ramp increment decreases steady state V̇O2 and reduces the initial and steady state lactate concentration ([La-]) as opposed to a standard step-transition to the same WR; (ii) increasing total hemoglobin concentration ([TotHb]) before reaching the target heavy-intensity WR via a ramp decreases muscle activation and the interaction (i.e., the ratio) between muscle activation and [TotHb] aligned with V̇O2, suggesting a tight link between the interplay of these physiological parameters; (iii) priming exercise accelerates the overall subsequent ramp incremental (RI) V̇O2 response by shortening the mean response time (MRT), extends the V̇O2max plateau and increases peak power output (POpeak). Collectively, these findings provide new insights into the mechanisms leading to the increased O2 cost of exercise, the interplay between muscle hemodynamics and muscle activation with V̇O2, and the beneficial effects of priming exercise on RI test to improve cardiovascular fitness assessment.
Curve-counting invariants and crepant resolutions of Calabi-Yau threefolds

description: The Donaldson-Thomas (DT) theory of a Calabi-Yau threefold X gives rise to subtle deformation invariants. They are considered to be the mathematical counterparts of BPS state counts in topological string theory compactified on X. Principles of physics indicate that the string theory of a singular Calabi-Yau threefold and that of its crepant resolution ought to be equivalent, so one might expect that the DT theory of a singular Calabi-Yau threefold ought to be equivalent to that of its crepant resolution. There is some difficulty in defining DT when X is singular, but Bryan, Cadman, and Young have (in some generality) defined DT theory in the case where X is the coarse moduli space of an orbifold χ. The crepant resolution conjecture of Bryan-Cadman-Young gives a formula determining the DT invariants of the orbifold in terms of the DT invariants of the crepant resolution. In this dissertation, we begin a program to prove the crepant resolution conjecture using Hall algebra techniques inspired by those of Bridgeland.

description: This study examined newcomer-settler citizenship as a personal and scholastic response to the Truth and Reconciliation Commission’s Call to Action 94. With the guidance of Indigenous principles, including relationality, respect, interconnectedness, and reciprocity, I engaged with newcomer-settlers and Indigenous peoples working in the immigration and settlement sector to consider, “How can I be the best relative that I can be, and learn from others, while living on these Blackfoot, Stoney Nakoda, Tsuut’ina, and Métis lands that my settler-colonial family and I call home?” This Indigenist, interpretative, mixed methods research study has helped me to more fully understand the costs paid by Indigenous peoples to support my standard of living and comfort on these lands. Through relationships and this research process, I have also come to recognize an ethical and decolonizing way of being—called reciprocal citizenship—whereby non-Indigenous peoples can challenge settler-colonialism’s inherent oppression by centering Indigenous truths, dignity, and liberty in their thoughts, actions, and words. Reciprocal citizenship is about the ethical acts of giving back for the gifts of living on these lands, and seven actions revealed through this study include: respecting Indigenous-settler relationships; critically self-reflecting on oppression in Canada; acknowledging one’s own moves to innocence and comfort; seeking to learn; growing settler-colonial awareness; imagining shared futures; and actioning personal responsibilities that are guided in relationship with Indigenous peoples, knowledge systems, and the land. Reciprocal citizenship brings together citizenship education, transformative learning, and reconciliatory education. It asks both newcomer-settlers and established-settlers to step into their citizenship responsibilities, so that all can live in mutual respect and flourish on these lands that that we now call Canada.
