description: Searches for anomalies are a significant motivation for the LHC and help define key analysis steps, including triggers. We discuss specific examples how LHC anomalies can be defined through probability density estimates, evaluated in a physics space or in an appropriate neural network latent space, and discuss the model-dependence in choosing an appropriate data parameterisation. We illustrate this for classical k-means clustering, a Dirichlet variational autoencoder, and invertible neural networks. For two especially challenging scenarios of jets from a dark sector we evaluate the strengths and limitations of each method.

Agent-State Construction with Auxiliary Inputs
Creators: Tao, Ruo Yu
Publisher: name: University of Alberta Library
Year: 2022

In most, if not every, realistic sequential decision-making tasks, the decision-making agent is not able to model the full complexity of the world. In reinforcement learning, the environment is often much larger and more complex than the agent, a setting also known as partial observability. In such settings, the agent must leverage more than just the current sensory inputs; it must construct an agent state that summarizes the agent’s previous interactions with the world. Currently, the most common approach to tackle such a problem is to learn the agent-state function with a recurrent network. This is done with the agent’s sensory stream as input, which is often augmented with transformations of the agent’s observation. These augmentations are done in multiple ways, from simple approaches like concatenating observations to more complex ones such as uncertainty estimates or predictive representations. Nevertheless, although ubiquitous in the field, these additional inputs, which we term auxiliary inputs, are rarely emphasized, and it is not clear what their role or impact is. In this work we formalize agent-state construction with auxiliary inputs and present several examples of auxiliary inputs that incorporate information from the past, present, and/or future of the agent-environment interaction. We show that auxiliary inputs allow an agent to discriminate between observations that would otherwise be aliased, leading to more expressive features that smoothly interpolate between different states. We empirically evaluate this agent-state construction with different function approximators, using different instantiations of these auxiliary inputs across a variety of tasks. This approach is complementary to state-of-the-art methods such as recurrent neural networks, and acts as a heuristic that facilitates longer temporal credit assignment, reducing the number of time steps needed when performing truncated backpropagation through time and leading to better performance.

L’anxiété Langagière chez des Étudiants (es) de Niveau Universitaire qui Suivent des Cours de Français et dont la Langue Première est L’anglais

Language anxiety (LA) is a relatively common phenomenon that is likely to negatively influence the well-being and success of students learning a second language. Despite this, very few studies on this type of anxiety experienced by English-speaking students from French immersion environments who must take French courses in order to complete their university course have been conducted. The gap in this area of research prompted us to systematically examine the impact that AL may have on a small group of English-speaking students enrolled in French courses at the Faculté Saint-Jean (FSJ) of the University of Alberta. To do this, we passed the Foreign Language Classroom Anxiety Scale (FLCAS) questionnaire to seven students in order to measure their AL level. We also conducted semi-structured interviews with these same students and with five FSJ professors who teach French. The analysis of the data allowed us to see that AL would be higher among first-year students than among second- and third-year students. These analyzes also allowed us to recommend relevant educational strategies for university-level French teachers who are concerned with helping English-speaking students with AL to reduce this form of anxiety.

description: The paper is a study of geodesic in two-dimensional pseudo-Riemannian metrics. Firstly, the local properties of geodesics in a neighborhood of generic parabolic points are investigated. The equation of the geodesic flow has singularities at such points that leads to a curious phenomenon: geodesics cannot pass through such a point in arbitrary tangential directions, but only in certain directions said to be admissible (the number of admissible directions is generically 1 or 3). Secondly, we study the global properties of geodesics in pseudo-Riemannian metrics possessing differentiable groups of symmetries. At the end of the paper, two special types of discontinuous metrics are considered.

description: As obligate, intracellular parasites, viruses rely on host factors for their replication. High throughput siRNA screens are an effective approach for identifying host-virus interactions. We are interested in identifying host-virus interactions in human cytomegalovirus (HCMV), a clinically important herpesvirus. Previously, Valosin-containing protein, a key component of the ubiquitin-proteasome system (UPS), was identified as a host-factor important for HCMV replication using an siRNA screen. To understand the importance of UPS in HCMV infection, we performed an siRNA screen against the ubiquitin-modifying enzymes. From this screen we identified numerous pro- and antiviral host factors that impact HCMV replication. Here we have selected two of the antiviral host factors, Remodelling and spacing factor 1 (RSF1) and F-box and leucin-rich repeat protein 20 (FBLX20), for further investigation. RSF1 has previously been shown to regulate gene expression through binding to ubiquitinated histones. We have shown that knockdown of RSF1 leads to an increase in expression of the major immediate early (MIE) genes IE1 and IE2, which are critical for driving acute replication of the virus. Furthermore, RSF1 colocalises with the HCMV replication compartment, where viral genome replication and transcription occur, suggesting RSF1 may be directly interacting with the viral genome to regulate the MIE promoter. FBXL20 is a substrate receptor of a cullin-RING E3 ligase complex. Here we discovered that knocking down FBXL20 leads to a significant decrease in interferon (IFN) production during HCMV infection. This decrease was similar to levels achieved by knocking down cGAS, the major HCMV pathogen recognition receptor, which has previously been shown to be necessary for efficient IFN upregulation triggered by HCMV infection. Decreased levels of FBXL20 also leads to reduced induction of interferon-stimulated genes. This suggests that FBXL20 is involved in regulation of the interferon signalling pathway. In summary, we have identified two ubiquitin-modifying enzymes that play a major role in restricting HCMV replication through two distinct pathways: via interaction with the incoming genome and through regulation of innate immunity.
Neurosteroid modulation of GABAergic neurotransmission in the central amygdala: A role for NMDA receptors

description: The neurosteroid 3α-hydroxy-5α-pregnan-20-one (allopregnanolone or ALLO) positively modulates GABAA receptors, an action that may contribute to the anxiolytic effects of ALLO. Recent evidence suggests that ALLO’s anxiolytic effects appear to be mediated by the amygdala, a key neural structure for emotional and cognitive behaviors. However, little is known regarding ALLO effects on amygdala physiology. We therefore explored ALLO effects on GABA neurotransmission in the central nucleus (Ce) of the amygdala, a major output nucleus involved in fear and anxiety. We recorded evoked GABAA receptor-mediated inhibitory postsynaptic currents (IPSCs) in Ce neurons using whole-cell patch clamp techniques. We observed that ALLO significantly reduced the amplitude of evoked GABAA receptor-mediated IPSCs. However, the effect of ALLO was occluded by the NMDA receptor antagonist D-APV. D-APV alone also reduced evoked IPSCs in Ce neurons. These results suggest that ALLO-induced reduction of GABAergic transmission in Ce appears to depend on neural network activity, possibly involving an NMDA receptor-mediated mechanism. These ALLO effects on GABAergic transmission in the central amygdala may play a role in mediating its anxiolytic actions.

description: Antisymmetric tensor field (two-form field) is a ubiquitous component in string theory and generally couples to the scalar sector through its kinetic term. In this paper, we propose a cosmological scenario that the particle production of two-form field, which is triggered by the background motion of the coupled inflaton field, occurs at the intermediate stage of inflation and generates the sizable amount of primordial black holes as dark matter after inflation. We also compute the secondary gravitational waves sourced by the curvature perturbation and show that the resultant power spectra are testable with the future space-based laser interferometers.

Lu et al. measured the atomic isotope shifts (AIS) for $^{4,6,8}$He and determined proton radii $r_{p}({\rm AIS})$ for $^{4,6,8}$He. As for p+$^{4,6,8}$He scattering, reaction cross sections $σ_{\rm R}({\rm exp})$ are available at 700~MeV with high accuracy. Our aim is to determine matter radii $r_{m}$ and skins $r_{\rm skin}$ for $^{6,8}$He from the $σ_{\rm R}({\rm exp})$ and the $r_{p}({\rm AIS})$. {\bf Method:} Our model is the Love-Franey $t$-matrix folding model, since the model is better than the optical limit of Glauber model. Our results for $^{6,8}$He are $r_{m}({\rm exp})=2.48(3), 2.53(2)$~fm and $r_{\rm skin}=$0.78(3), 0.82(2)~fm. For $^{6,8}$He, our results $r_{m}(σ_{\rm R})$ agree with those of Tanihata {\it et al.}. For $^{8}$He, the distance between $^{4}$He and the center of mass of valence four neutrons is 2.367~fm.

description: The doctoral research work focused on problematizing, from a philosophical legal and political point of view, certain aspects of the thinking of the two best-known and most relevant economists of the 20th century, John Maynard Keynes and Friedrich August Hayek. The economic and social philosophy analysis of the works of the two authors was put under the scrutiny of two lines of inquiry: first of the relationship between the sphere of economics and the sphere of politics, and then, closely related to the first aspect, the different declinations of the concept of crisis. In the first part of the research, moving from a philosophical questioning, the concept of the modern was investigated from the constituent character that the relationship between the Political and the Economic has assumed. Within this framework it was possible to examine mainly, two fundamental concepts of the legal philosophical lexicon: that of the individual and that of the State. In the second part, however, the same issue was analyzed in the light of the thought, first, of the Cambridge economist and later of the Viennese. In the second chapter of the thesis, in fact, three topical moments are distinguished that allow the notion of Keynesian crisis to be delineated, highlighting the tension between economic science and politics. First, the monetary question, which intensely marks Keynes' thinking between the 1920s and his death in 1946, then reflections on the crisis of the liberal order that opened with the end of nineteenth-century laissez-faire, and finally, Keynes' diplomatic work during the two world wars define three determinations of Keynesian work. In the third chapter, the figure of Hayek is developed in two directions: the purely economic work developed between the 1920s and early 1940s, when the Viennese's analysis focused on the definition of the business cycle and the identification of crisis as an intervention by public authorities in the naturalness of the cycle; secondly, however, the research focused on the works of his maturity, when the new Hayekian definition of crisis, the one revolving around the notion of catallaxy, assumes and highlights the anti-modern bearing of Hayek's political philosophy. The whole reflection is mainly aimed at relating the two authors, both, more generally, from the point of view of their intellectual and biographical relationship, and by highlighting the different normative proposal internal to their interpretation, which the two theorists developed by differentially tensioning the dyad constituted by the terms Economic and Political.

description: Globalization is one of the central concepts of our age. The common perception of the process is that, due to declining communication and transport costs, distance becomes less and less important. However, the distance coefficient in the gravity model of trade, which grows in time, indicates that the role of distance increases rather than decreases. This, in essence, captures the notion of the globalization puzzle. Here, we show that the fractality of the international trade system (ITS) provides a simple solution for the puzzle. We argue, that the distance coefficient corresponds to the fractal dimension of ITS. We provide two independent methods, box counting method and spatial choice model, which confirm this statement. Our results allow us to conclude that the previous approaches to solving the puzzle misinterpreted the meaning of the distance coefficient in the gravity model of trade.

description: We present results of tight-binding spin-dynamics simulations of individual and pairs of substitutional Mn impurities in GaAs. Our approach is based on the mixed quantum-classical scheme for spin dynamics, with coupled equations of motions for the quantum subsystem, representing the host, and the localized spins of magnetic dopants, which are treated classically. In the case of a single Mn impurity, we calculate explicitly the time evolution of the Mn spin and the spins of nearest-neighbors As atoms, where the acceptor (hole) state introduced by the Mn dopant resides. We relate the characteristic frequencies in the dynamical spectra to the two dominant energy scales of the system, namely the spin-orbit interaction strength and the value of the p-d exchange coupling between the impurity spin and the host carriers. For a pair of Mn impurities, we find signatures of the indirect (carrier-mediated) exchange interaction in the time evolution of the impurity spins. Finally, we examine temporal correlations between the two Mn spins and their dependence on the exchange coupling and spin-orbit interaction strength, as well as on the initial spin-configuration and separation between the impurities. Our results provide insight into the dynamic interaction between localized magnetic impurities in a nano-scaled magnetic-semiconductor sample, in the extremely dilute (solotronics) regime.

description: Hypothalamic neurons expressing neuropeptide orexins are critically involved in the control of sleep and wakefulness. Although the activity of orexin neurons is thought to be influenced by various neuronal input as well as humoral factors, the direct consequences of changes in the activity of these neurons in an intact animal are largely unknown. We therefore examined the effects of orexin neuron-specific pharmacogenetic modulation in vivo by a new method called the Designer Receptors Exclusively Activated by Designer Drugs approach (DREADD). Using this system, we successfully activated and suppressed orexin neurons as measured by Fos staining. EEG and EMG recordings suggested that excitation of orexin neurons significantly increased the amount of time spent in wakefulness and decreased both non-rapid eye movement (NREM) and rapid eye movement (REM) sleep times. Inhibition of orexin neurons decreased wakefulness time and increased NREM sleep time. These findings clearly show that changes in the activity of orexin neurons can alter the behavioral state of animals and also validate this novel approach for manipulating neuronal activity in awake, freely-moving animals.
Ensembles of Neural Networks for Tumour Motion Prediction
Creators: Johnson, Neil Wallace
Publisher: name: University of Alberta Library
Year: 2022

Dynamic tumour-tracked radiotherapy is a promising method for delivering conformal doses to tumours that exhibit a large degree of motion as a result of patient respiration. However, there exists an inevitable latency between the acquisition of an image of a moving tumour and the adaptation of the therapeutic beam to match its observed position and contour. This must be addressed by predicting respiration-induced tumour motion so that the requisite mechanical adjustments can be initiated sufficiently in advance. For MR-based tracking, this latency is relatively long compared to other imaging techniques. Accurate motion prediction therefore requires a more sophisticated approach than those used for short-latency hardware.

A novel application of long short-term memory recurrent neural networks for respiration-induced tumour motion is presented in this thesis. It consists of three main components: (1) acceleration of training using super-convergence regularization with intelligent early stopping; (2) mitigation of overfitting and instability through homogeneous network ensembles; and (3) improvement of the reaction to changing respiratory patterns during treatment through a novel adaptation method called intermittent retraining. Compared to previous studies, this approach reduces the amount of time required for network training by several orders of magnitude while simultaneously improving the accuracy and consistency of predictions. This work represents a step toward bringing linac-MR based dynamic tumour-tracked radiotherapy into clinical relevance by making it both more practical and more precise.

description: Deep neural networks have seen tremendous success over the last years. Since the training is performed on digital hardware, in this paper, we analyze what actually can be computed on current hardware platforms modeled as Turing machines, which would lead to inherent restrictions of deep learning. For this, we focus on the class of inverse problems, which, in particular, encompasses any task to reconstruct data from measurements. We prove that finite-dimensional inverse problems are not Banach-Mazur computable for small relaxation parameters. Even more, our results introduce a lower bound on the accuracy that can be obtained algorithmically.

description: Reliable processing of quantum information is a milestone to achieve for the deployment of quantum technologies. Uncontrolled, out-of-equilibrium sources of decoherence need to be characterized in detail for designing the control of quantum devices to mitigate the loss of quantum information. However, quantum sensing of such environments is still a challenge due to their non-stationary nature that in general can generate complex high-order correlations. We here introduce a path integral framework to characterize non-stationary environmental fluctuations by a quantum probe. We found the solution for the decoherence decay of non-stationary, generalized Gaussian processes that induce pure dephasing. This dephasing when expressed in a suitable basis, based on the non-stationary noise eigenmodes, is defined by the overlap of a generalized noise spectral density and a filter function that depends on the control fields. This result thus extends the validity to out-of-equilibrium environments, of the similar general expression for the dephasing of open quantum systems coupled to stationary noises. We show physical insights for a broad subclass of non-stationary noises that are local-in-time, in the sense that the noise correlation functions contain memory based on constraints of the derivatives of the fluctuating noise paths. Spectral and non-Markovian properties are discussed together with implementations of the framework to treat paradigmatic environments that are out-of-equilibrium, e.g. due to a quench and a pulsed noise. We show that our results provide tools for probing the spectral and time-correlation properties, and for mitigating decoherence effects of out-of-equilibrium -- non-stationary -- environments.

Year: 2012

description: Mannitol has traditionally been the mainstay of medical therapy for intracranial hypertension in patients with head injury. We previously demonstrated that mannitol reduces brain volume in patients with cerebral edema, although whether this occurs due to a reduction in brain water, blood volume or both remains poorly understood.
Groups with $\mathsf A_\ell$-commutator relations

description: If $A$ is a unital associative ring and $\ell \geq 2$, then the general linear group $\mathrm{GL}(\ell, A)$ has root subgroups $U_α$ and Weyl elements $n_α$ for $α$ from the root system of type $\mathsf A_{\ell - 1}$. Conversely, if an arbitrary group has such root subgroups and Weyl elements for $\ell \geq 4$ satisfying natural conditions, then there is a way to recover the ring $A$. We prove a generalization of this result not using the Weyl elements, so instead of the matrix ring $\mathrm M(\ell, A)$ we construct a non-unital associative ring with a well-behaved Peirce decomposition.

description: This is number sixteen of 42 preservation briefs prepared by the Technical Preservation Services of the National Park Service. This brief focuses on the use of substitute materials on historic building exteriors. This Brief provides general guidance on the use of substitute materials on the exteriors of historic buildings. While substitute materials are frequently used on interiors, these applications are not subject to weathering and moisture penetration, and will not be discussed in this Brief. Given the general nature of this publication, specifications for substitute materials are not provided. The guidance provided should not be used in place of consultations with qualified professionals. This Brief includes a discussion of when to use substitute materials, cautions regarding their expected performance, and descriptions of several substitute materials, their advantages and disadvantages. This review of materials is by no means comprehensive, and attitudes and findings will change as technology develops.

description: As a step toward a comprehensive overview of the infrared diagnostics of the central engines and host galaxies of quasars at low redshift, we present Spitzer Space Telescope spectroscopic (5-40 μm) and photometric (24, 70 and 160 μm) measurements of all Palomar-Green (PG) quasars at z < 0.5 and 2MASS quasars at z < 0.3. We supplement these data with Herschel measurements at 160 μm. The sample is composed of 87 optically selected PG quasars and 52 near-IR selected 2MASS quasars. Here we present the data, measure the prominent spectral features, and separate emission due to star formation from that emitted by the dusty circumnuclear torus. We find that the mid-IR (5-30 μm) spectral shape for the torus is largely independent of quasar IR luminosity with scatter in the SED shape of ~ 0.2 dex. Except for the silicate features, no large difference is observed between PG (unobscured - silicate emission) and 2MASS (obscured - silicate absorption) quasars. Only mild silicate features are observed in both cases. When in emission, the peak wavelength of the silicate feature tends to be longer than 9.7 μm, possibly indicating effects on grain properties near the AGN. The IR color is shown to correlate with the equivalent width of the aromatic features, indicating that the slope of the quasar mid- to far-IR SED is to first order driven by the fraction of radiation from star formation in the IR bands.

description: Associated Particle Imaging (API) utilizes the inelastic scattering of neutrons produced in deuterium-tritium fusion reactions to obtain 3-D isotopic distributions within an object. The locations of the inelastic scattering centers are calculated by measuring the arrival time and position of the associated alpha particle produced in the fusion reactions, and the arrival time of the prompt gamma created in the neutron scattering event. While the neutron and its associated particle move in opposite directions in the center-of-mass (COM) system, in the laboratory system the angle is slightly less than 180 degree, and the COM movement must be taken into account in the reconstruction of the scattering location. Furthermore, the fusion reactions are produced by ions of different momenta, and thus the COM velocity varies, resulting in an uncertainty in the reconstructed positions. In this article, we analyze the COM corrections to this reconstruction by simulating the energy loss of beam ions in the target material and identifying sources of uncertainty in these corrections. We show that an average COM velocity calculated using the ion beam direction and energy can be used in the reconstruction and discuss errors as a function of ion beam energy, composition, and alpha detection location. When accounting for the COM effect, the mean of the reconstructed locations can be considered a correctable systematic error leading to a shift/tilt in the reconstruction. However, the distribution of reconstructed locations also have a spread that will introduce an error in the reconstruction that cannot be corrected. In this article, we will use the known stopping powers of ions in materials and reaction cross sections to examine the reconstruction uncertainties. We also discuss the impact of this effect on our API system.

Re-Working Statistics: An Indigenous Quantitative Methodological Approach to Labour Market Research
Creators: Lindquist, Kelsey
Publisher: name: University of Alberta Library
Year: 2022

Indigenous labour market statistics are a key technology through which the Canadian nation-state reaffirms its possession of Indigenous land. Colonizing settler norms, values, and racialized understandings inform the dominant methodological approach to Indigenous labour market statistics resulting in the persistent production of deficit-based, racialized statistical depictions of Indigeneity. The purported objectivity and neutrality of quantitative data, however, obscures the racialized origins and parameters of dominant statistical research on Indigenous labour market outcomes. This thesis denaturalizes the dominant methodological approach to Indigenous labour market statistics.

The process of denaturalizing the dominant quantitative methodology undertaken in this thesis is twofold. First, I explicate colonizing power relations at three different levels of abstraction to expose the dominant social, cultural, and racial terrain from which Indigenous labour market statistics emerge. I engage with Marxist theories of capitalism and Aileen Moreton-Robinson’s (2015) theorization of patriarchal white sovereignty to construct a general framework for theorizing colonizing settler societies, before drawing on Indigenous labour histories and critical Indigenous demography to refine this framework to the particular Canadian context. Using this framework, I conduct a critical analysis of quantitative academic research on Indigenous labour market outcomes. Second, I explore the development of an Indigenous quantitative methodology in the context of work and labour research. I discuss three strategies for advancing an Indigenous quantitative research agenda on work and labour, before translating one of these strategies into practice. Specifically, using data from the General Social Survey 2016, I explore the development of a statistical model that focuses on structural inequality rather than Indigenous deficit.
