description: This article examines the impacts of Eurozone crisis, COVID-19 and Russia- Ukraine war on stock market integration and risk contagion for five largest stock markets of developed countries (Hong Kong, USA, UK, Japan, and Canada) in the post financial crisis period. Weekly data from 2010 to 2023 has been tested by employing multivariate GARCH DCC model. We find existence of significant comovement between market returns of five countries during the sample period with a significant contagion effect between all during the Eurozone crisis. However, during the COVID period, existence of risk contagion has been established amongst USA, UK, Japan and Canada. Furthermore, our findings reveal the presence of ‘flight to quality effects’ among all five stock markets during Russia- Ukraine war and also when Hong-Kong stock market is paired with rest four during the COVID period. The results highlight the importance of policy coordination amongst the world’s major developed economies.

description: OBJECTIVES: Most patients with anti-NMDA receptor (NMDAR) encephalitis have intrathecal synthesis of antibodies, which cause a decrease of cell surface and synaptic NMDAR. Antibodies are immunoglobulin G (IgG)1 and IgG3 subtypes and can potentially activate complement. We examined whether complement immunoreactivity and antibody-secreting cells (plasma cells/plasmablasts) are present in the brain of these patients.

METHODS: Cultured rat hippocampal neurons were used in an immunocytochemical assay to test whether patients' antibodies can fix complement. Using the same reagents (antibodies to C9neo, C(5b-9), C3), complement immunoreactivity was determined in the brain of 5 patients, the teratoma of 21 patients, and appropriate control tissues. A set of markers for B (CD20), T (CD3, CD4, CD8) and antibody-secreting cells (plasma cells/plasmablasts, CD138) were used to examine the brain inflammatory infiltrates.

RESULTS: Patients' antibodies were able to bind complement in vitro, but deposits of complement were not detected in patients' brain. Parallel experiments with teratomas showed that in contrast to the brain, the neural tissue of the tumors contained complement. Analysis of the inflammatory infiltrates in brain samples from autopsy or biopsy performed 3-4 weeks after symptom presentation demonstrated numerous antibody-secreting cells (CD138+) in perivascular, interstitial, and Virchow-Robin spaces, and B and T cells predominantly located in perivascular regions.

CONCLUSIONS: Complement-mediated mechanisms do not appear to play a substantial pathogenic role in anti-NMDAR encephalitis. In contrast, there are copious infiltrates of antibody-secreting cells (plasma cells/plasmablasts) in the CNS of these patients. The demonstration of these cells provides an explanation for the intrathecal synthesis of antibodies and has implications for treatment.

Greenhouse Gas Emissions from Canadian Agriculture: Policies and Reduction Measures

Publisher: name: The School of Public Policy Publications
Year: 2022

description: Despite numerous national and international climate conferences, meetings and workshops leading to various greenhouse gas (GHG) emission targets and agreements since the 1970s, total GHG emissions in Canada continue to increase. They reached 729 megatonnes of carbon dioxide equivalent (Mt CO2 eq) in 2018, with the Canadian agricultural sector contributing approximately 10 per cent of total GHGs emitted. Different regions of the country contribute different levels, face different challenges and have different capacities to address their GHG emissions. Designing climate guidelines, programs, policies and adopting best management practices (BMPs) that promote relevant local and regional adaptation and mitigation efforts is important. Mechanisms such as setting a carbon price, cap- and-trade systems and tax-based policies contribute to decreased GHG emissions. GHG emissions in Canada are regulated at the federal level via a national carbon pricing policy and provinces have set limitations on GHG emissions via pricing or taxation. Agriculture has the potential to mitigate GHG emissions by applying BMPs that reduce emissions and increase carbon storage in soils. Meanwhile, the pressure is increasing on the agricultural sector to increase production, both for local commodities and those destined for export, to feed a growing population. This paper explores agricultural policies and measures that encourage farmers and producers across Canada to reduce their GHG emissions. Specifically, national and provincial measures and implications are presented and compared to international measures and outcomes. Finally, recommendations are made for future climate policy research and adoption.

description: OBJECTIVES: Stroke risk immediately after TIA defined by time-based criteria is high, and prognostic scores (ABCD2 and ABCD3-I) have been developed to assist management. The American Stroke Association has proposed changing the criteria for the distinction between TIA and stroke from time-based to tissue-based. Research using these definitions is lacking. In a multicenter observational cohort study, we have investigated prognosis and performance of the ABCD2 score in TIA, subcategorized as tissue-positive or tissue-negative on diffusion-weighted imaging (DWI) or CT imaging according to the newly proposed criteria.

METHODS: Twelve centers provided data on ABCD2 scores, DWI or CT brain imaging, and follow-up in cohorts of patients with TIA diagnosed by time-based criteria. Stroke rates at 7 and 90 days were studied in relation to tissue-positive or tissue-negative subcategorization, according to the presence or absence of brain infarction. The predictive power of the ABCD2 score was determined using area under receiver operator characteristic curve (AUC) analyses.

RESULTS: A total of 4,574 patients were included. Among DWI patients (n = 3,206), recurrent stroke rates at 7 days were 7.1%(95% confidence interval 5.5-9.1) after tissue-positive and 0.4% (0.2-0.7) after tissue-negative events (p diff < 0.0001). Corresponding rates in CT-imaged patients were 12.8% (9.3-17.4) and 3.0% (2.0-4.2), respectively (p diff < 0.0001). The ABCD2 score had predictive value in tissue-positive and tissue-negative events (AUC = 0.68 [95% confidence interval 0.63-0.73] and 0.73 [0.67-0.80], respectively; p sig < 0.0001 for both results, p diff = 0.17). Tissue-positive events with low ABCD2 scores and tissue-negative events with high ABCD2 scores had similar stroke risks, especially after a 90-day follow-up.

CONCLUSIONS: Our findings support the concept of a tissue-based definition of TIA and stroke, at least on prognostic grounds.
Highest weight and boundary states of vertex operator algebra modules from Airy ideals
Creators: Joshi, Aniket
Publisher: name: University of Alberta Library
Year: 2022

In this thesis we study some aspects of `Airy structures' first proposed in \cite{ks}, as an algebraic reformulation of the Chekhov-Eynard-Orantin (CEO) topological recursion initiated in \cite{eo} and \cite{eo1} in order to study the large $N$ expansion of matrix models.

Our primary goal is to engineer new examples of Airy structures taking inspiration from the representation theory of vertex operator algebras. In particular, we construct a highest weight state of a $\mathcal{W}^{-N-1/2}(\mathfrak{sp}_{2N})$-algebra module as a partition function of an Airy structure, following the approach developed in \cite{Airy}. We do this with the help of an orbifold construction from symplectic fermions that was developed in \cite{cl}. Our second key result is the construction of certain Ishibashi boundary states related to affine vertex algebra modules from partition functions of Airy structures. We make use of the Wakimoto free field realizations of affine Lie algebras for this purpose. A novel aspect of both of these examples is that zero modes of the Heisenberg algebra are realized as derivatives instead of variables, and hence the partition functions are vectors that lie in infinite indecomposable extensions of Fock modules of free field algebras.

On the other hand, we also give an alternate formulation of Airy structures as left ideals of $\hbar$-adic completions of  Rees Weyl algebras. In particular, we obtain a different proof of the existence and uniqueness of partition functions of Airy structures by realizing Airy ideals' as homomorphic images of canonical left ideals generated by derivatives obtained via certain automorphisms of the Rees Weyl algebra calledtransvections'.
Fault-tolerant syndrome extraction and cat state preparation with fewer qubits

Year: 2021

description: We reduce the extra qubits needed for two fault-tolerant quantum computing protocols: error correction, specifically syndrome bit measurement, and cat state preparation. For distance-three fault-tolerant syndrome extraction, we show an exponential reduction in qubit overhead over the previous best protocol. For a weight-$w$ stabilizer, we demonstrate that stabilizer measurement tolerating one fault needs at most $\lceil \log_2 w \rceil + 1$ ancilla qubits. If qubits reset quickly, four ancillas suffice. We also study the preparation of entangled cat states, and prove that the overhead for distance-three fault tolerance is logarithmic in the cat state size. These results apply both to near-term experiments with a few qubits, and to the general study of the asymptotic resource requirements of syndrome measurement and state preparation. With $a$ flag qubits, previous methods use $O(a)$ flag patterns to identify faults. In order to use the same flag qubits more efficiently, we show how to use nearly all $2^a$ possible flag patterns, by constructing maximal-length paths through the $a$-dimensional hypercube.

Carbon Credit Systems in Agriculture: A Review of Literature
Creators: name: Lokuge, Nimanthika
name: Anders, Sven
Publisher: name: The School of Public Policy Publications
Year: 2022

description: Carbon-credit systems allow agricultural producers to earn an extra revenue through selling their surplus of carbon credits to producers who emit higher amounts of greenhouse gases (GHGs). However, agricultural carbon-credit systems are still at early stage; hence, these benefits cannot be guaranteed due to their uncertain nature and the paucity of scientific evidence about agricultural carbon credits. The objective of this study is to provide a comprehensive literature review to highlight the gaps in existing knowledge related to agricultural carbon credits/offsets. Our particular interest is on Alberta because the province indicates the highest agricultural GHG emissions from 1990 to 2019 and, therefore, developing strategies to reduce the sector’s carbon intensity without compromising its economic contribution to the provincial economy poses a challenge. Literature is evident for promising GHG-mitigation strategies such as adoption of 4R practices (the right source at the right rate, right time and right place) as a package and improved efficiency in cattle farm management. Reduced tillage has been found to be less efficient. Researchers favour the concept of regenerative agriculture, which is more likely to return better outcomes compared to tillage practices. Moreover, ranchers are willing to upgrade their farms with efficient cattle breeds to take advantage of decreased feed costs. Conversely, farmers are reluctant to participate in the Alberta Emission Offset System unless rewarded with incentives. However, carbon-credit markets are still growing; consequently, farmers may have more opportunities in the future. If the Alberta credit price continues to grow with no expected increase in transaction costs, agricultural producers would be more attracted to participate in the Alberta Emission Offset System. Moreover, endorsing farmers for carbon-crediting mechanisms by emphasizing the co-benefits and associated economic incentives is recommended, instead of prioritizing its potential financial gains. Nevertheless, due to the scarcity of published studies, it is too early to project the economic and climate-mitigative potential of carbon-offset–credit markets for Canadian farmers. Literature suggests farmers wait until the carbon market becomes more stable before making a decision. Future research and scientific evidence will be crucial to filling these gaps and to guaranteeing future protocols.

Reducing Transaction Costs on Infrastructure Corridor Projects in Canada
Creators: name: Le Dressay, André
Publisher: name: The School of Public Policy Publications
Year: 2022

description: Infrastructure corridors are among the most complicated transactions in Canada. Establishing a pre-determined corridor and completing linear infrastructure projects within it requires transactions related to property rights, infrastructure planning, design, construction, financing, operation and maintenance, securing public support or social license, and because of the long overdue recognition of Indigenous rights and title, informed support from impacted Indigenous communities. This paper uses a comparative systems analysis to identify specific transaction costs in four areas – historic, infrastructure development process, fiscal and economic systems. We argue these transaction costs can be significantly reduced by systematically implementing Indigenous fiscal, infrastructure and lands jurisdictions because this will permanently ensure that Indigenous communities and people are able to receive similar fiscal and economic benefits generated from infrastructure corridor projects as those enjoyed by other Canadians and other governments.

description: OBJECTIVE: To provide clinical data on a cohort of 6 patients with massive expansion (>200 CAG repeats) of spinocerebellar ataxia type 2 (SCA2) and investigate possible pathways of pathogenesis using bioinformatics analysis of ATXN2 networks.

METHODS: We present data on 6 patients with massive expansion of SCA2 who presented in infancy with variable combinations of hypotonia, global developmental delay, infantile spasms, and retinitis pigmentosa. ATXN2 is known to interact with a network of synaptic proteins. To investigate pathways of pathogenesis, we performed bioinformatics analysis on ATXN2 combined with known genes associated with infantile spasms, retinitis pigmentosa, and synaptic function.

RESULTS: All patients had a progressive encephalopathy with autonomic dysfunction, 4 had retinitis pigmentosa, and 3 had infantile spasms. The bioinformatics analysis led to several interesting findings. First, an interaction between ATXN2 and SYNJ1 may account for the development of retinitis pigmentosa. Second, dysfunction of postsynaptic vesicle endocytosis may be important in children with this progressive encephalopathy. Infantile spasms may be associated with interactions between ATXN2 and the postsynaptic structural proteins MAGI2 and SPTAN1.

CONCLUSIONS: Severe phenotype in children with massive expansion of SCA2 may be due to a functional deficit in protein networks in the postsynapse, specifically involving vesicle endocytosis.
The Sensitivity of Food Bank Visits to Social Assistance, Housing and Labour Market Conditions in Toronto

description: We make use of monthly data describing the number of visits to food banks operated by the Daily Bread Food Bank in Toronto. We identify the extent to which food bank visits may be associated with changes to public policies, to changes in the cost of shelter and to changes in labour market conditions. Our measures of these changes are those that are relevant to individuals and families with limited incomes and limited abilities to borrow or save. We find that the number of visits to food banks is sensitive to measures of all three of these types of changes; food bank visits increase with increases in rent, with falls in the minimum wage and with reductions in the disability benefits available to people requiring social assistance.

description: Quantum-enhanced computing methods are promising candidates to solve currently intractable problems. We consider here a variational quantum eigensolver (VQE), that delegates costly state preparations and measurements to quantum hardware, while classical optimization techniques guide the quantum hardware to create a desired target state. In this work, we propose a bosonic VQE using superconducting microwave cavities, overcoming the typical restriction of a small Hilbert space when the VQE is qubit based. The considered platform allows for strong nonlinearities between photon modes, which are highly customisable and can be tuned in situ, i.e. during running experiments. Our proposal hence allows for the realization of a wide range of bosonic ansatz states, and is therefore especially useful when simulating models involving degrees of freedom that cannot be simply mapped to qubits, such as gauge theories, that include components which require infinite-dimensional Hilbert spaces. We thus propose to experimentally apply this bosonic VQE to the U(1) Higgs model including a topological term, which in general introduces a sign problem in the model, making it intractable with conventional Monte Carlo methods.

Star Formation in Cygnus X
Creators: Deb, Soumen
Publisher: name: University of Alberta Library
Year: 2022

In astrophysics, stellar evolution is one of the most discussed topics. Although a significant amount of research and advancement of instrumentation over the last few decades have contributed to this field greatly, our understanding of the pre-main sequence evolution remains largely incomplete. The general model for the formation of protostars within the ISM is the virial instability in cold molecular gas resulting in spontaneous gravitational collapse. However, the complete understanding of this instability requires a set of other physical factors, including the hydrodynamic turbulence in the ISM, local magnetic field strength, and feedback from surrounding high-mass stars, not all of them are well-understood. This work investigates the effect of stellar feedback on local star formation and the extent of energy support for molecular clouds provided by protostellar outflows within them.

I first look into a specific case of potentially triggered star formation in Cygnus X, being one of the most active star-forming regions in the Milky Way. Using multi-line submillimetre emissions as well as radio continuum and infrared data, I measure the properties of two highly energetic molecular outflows near the massive stellar complex Cygnus OB2 complex. I show structure, physical conditions, and timescale of the outflows and the associated photoionized rim are consistent with a triggering scenario.

I further investigate 13 such molecular outflows in Cygnus X and measure their properties using multi-line data which I find are similar to the previous surveys of outflows throughout the galaxy. Additionally, I develop and test a method to measure the same properties using single spectral line emission. This is useful in surveys where optically thin line data are not available.

Next, I implement our method to estimate outflow properties in a large-scale survey of 82 outflows, many of which were previously unknown, based on single spectral-line observations. I use machine learning to fill out missing information on protostellar luminosity using existing catalogues and investigate the comparative predictive powers of line emission and radio continuum data on local outflow formation. Next, by comparing outflow power to turbulent dissipation power I show that single-generational outflows cannot provide enough energy support for the surrounding molecular clouds. Finally, I search for evidence of large-scale triggering of star formation and find that an ionization front can perhaps trigger local star formation where molecular gas emission is high, however, find no evidence for this effect to be strong.

description: We define and analyze a stochastic process in anti-de Sitter Jackiw-Teitelboim gravity, induced by the quantum dynamics of the boundary and whose random variable takes values in $AdS_2$. With the boundary in a thermal state and for appropriate parameters, we take the asymptotic limit of the quantum process at short time scales and flat space, and show associated classical joint distributions have the Markov property. We find that Einstein's equations of the theory, sans the cosmological constant term, arise in the semi-classical limit of the quantum evolution of probability under the asymptotic process. In particular, in flat Jackiw-Teitelboim gravity, the area of compactified space solved for by Einstein's equations can be identified as a probability density evolving under the Markovian process.

description: Fifty years after the invention of the laser diode and fourty years after the report of the butterfly effect - i.e. the unpredictability of deterministic chaos, it is said that a laser diode behaves like a damped nonlinear oscillator. Hence no chaos can be generated unless with additional forcing or parameter modulation. Here we report the first counter-example of a free-running laser diode generating chaos. The underlying physics is a nonlinear coupling between two elliptically polarized modes in a vertical-cavity surface-emitting laser. We identify chaos in experimental time-series and show theoretically the bifurcations leading to single- and double-scroll attractors with characteristics similar to Lorenz chaos. The reported polarization chaos resembles at first sight a noise-driven mode hopping but shows opposite statistical properties. Our findings open up new research areas that combine the high speed performances of microcavity lasers with controllable and integrated sources of optical chaos.

AN OVERVIEW AND ASSESSMENT OF KEY CONSTITUTIONAL ISSUES RELEVANT TO THE CANADIAN NORTHERN CORRIDOR
Creators: name: Newman, Dwight
Publisher: name: The School of Public Policy Publications
Year: 2022

description: This report considers at a high level a number of constitutional issues associated with the development of the proposed Northern Corridor, seeking to flag areas for further examination. It seeks to show how the Canadian Constitution offers mechanisms for such a multi-modal corridor but also poses barriers. In some ways, the challenge the Northern Corridor seeks to overcome is the presence of too many decision-makers on each individual transportation infrastructure project. The Canadian Constitution both offers ways past this problem and also replicates it. The first part of the paper examines constitutional rules relating to inter-delegation between the federal and provincial governments and suggests that cooperation and inter-delegation, drawing on models of past infrastructure projects, may offer a constitutional mechanism toward development of the Northern Corridor but that they require leadership and a lot of support from different actors. The second part considers what powers the federal government has on its own in relation to transportation infrastructure and concludes that these are very significant in the context of interprovincial/international transportation infrastructure but that unilateral federal action may still be undesirable for other reasons and that this power may just signal the role of federal leadership on the file. The third part considers the implications of constitutionalized Indigenous rights and suggests that there will be a need for close examination of various contexts and early engagement of Indigenous peoples in a project that could be beneficial for northern Indigenous communities, with many legal complexities otherwise present, including implications from Canada’s new legislation on the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP). A concluding section draws together key implications and suggests that the constitutional landscape calls for federal leadership but extensive engagement and cooperation with other actors, even while there remain many constitutional and legal issues that would warrant closer examination.

description: We investigate pitchfork bifurcations for a stochastic reaction diffusion equation perturbed by an infinite-dimensional Wiener process. It is well-known that the random attractor is a singleton, independently of the value of the bifurcation parameter; this phenomenon is often referred to as the "destruction" of the bifurcation by the noise. Analogous to the results of [Callaway et al., AIHP Probab. Stat., 53:1548-1574, 2017] for a 1D stochastic ODE, we show that some remnant of the bifurcation persists for this SPDE model in the form of a positive finite-time Lyapunov exponent. Additionally, we prove finite-time expansion of volume with increasing dimension as the bifurcation parameter crosses further eigenvalues of the Laplacian.

Bulk viscosity-driven suppression of shear viscosity effects on the flow harmonics at RHIC

description: The interplay between shear and bulk viscosities on the flow harmonics, $v_n$'s, at RHIC is investigated using the newly developed relativistic 2+1 hydrodynamical code v-USPhydro that includes bulk and shear viscosity effects both in the hydrodynamic evolution and also at freeze-out. While shear viscosity is known to attenuate the flow harmonics, we find that the inclusion of bulk viscosity decreases the shear viscosity-induced suppression of the flow harmonics bringing them closer to their values in ideal hydrodynamical calculations. Depending on the value of the bulk viscosity to entropy density ratio, $ζ/s$, in the quark-gluon plasma, the bulk viscosity-driven suppression of shear viscosity effects on the flow harmonics may require a re-evaluation of the previous estimates of the shear viscosity to entropy density ratio, $η/s$, of the quark-gluon plasma previously extracted by comparing hydrodynamic calculations to heavy ion data.

How do I update my model? On the resilience of Predictive Process Monitoring models to change

description: Existing well investigated Predictive Process Monitoring techniques typically construct a predictive model based on past process executions, and then use it to predict the future of new ongoing cases, without the possibility of updating it with new cases when they complete their execution. This can make Predictive Process Monitoring too rigid to deal with the variability of processes working in real environments that continuously evolve and/or exhibit new variant behaviours over time. As a solution to this problem, we evaluate the use of three different strategies that allow the periodic rediscovery or incremental construction of the predictive model so as to exploit new available data. The evaluation focuses on the performance of the new learned predictive models, in terms of accuracy and time, against the original one, and uses a number of real and synthetic datasets with and without explicit Concept Drift. The results provide an evidence of the potential of incremental learning algorithms for predicting process monitoring in real environments.
Obligatory Role of NR2A for Metaplasticity in Visual Cortex

description: Light deprivation lowers the threshold for long-term depression (LTD) and long-term potentiation (LTP) in visual cortex by a process termed metaplasticity, but the mechanism is unknown. The decreased LTD/P threshold correlates with a decrease in the ratio of NR2A to NR2B subunits of cortical NMDA receptors (NMDARs) and a slowing of NMDAR-mediated excitatory postsynaptic currents (EPSCs). However, whether and how changes in NR2 subunit expression contribute to LTD and LTP remains controversial. In the present study, we used an NR2A knockout (KO) mouse to examine the role of this subunit in the experience-dependent modulation of NMDAR properties, LTD, and LTP. In wild-type (WT) mice, we found what has previously been shown in rats, that dark rearing alters NMDAR EPSC kinetics and temporal summation, LTP, and LTD in layer 2/3 of visual cortex. Deletion of NR2A mimicked the effect of dark-rearing on NMDAR EPSCs, and there was no additional effect of dark-rearing in the NR2A KO mice. Thus, deletion of NR2A abrogates the effects of visual experience on NMDAR EPSCs. Moreover, metaplasticity of LTP and LTD was completely lost in the absence of NR2A. These data support the hypothesis that experience-dependent changes in NR2A/B are functionally significant and yield a mechanism for an adjustable synaptic modification threshold in visual cortex.
