description: We propose a scheme for the generation of counterpropagating polarization-entangled photon pairs from a dual-periodically poled crystal. Compared with the usual forward-wave type source, this source, in the backward-wave way, has a much narrower bandwidth. With a 2-cm-long bulk crystal, the bandwidths of the example sources are estimated to be 3.6 GHz, and the spectral brightnesses are more than 100 pairs/(s GHz mW). Two concurrent quasi-phase-matched spontaneous parametric down-conversion processes in a single crystal enable our source to be compact and stable. This scheme does not rely on any state projection and applies to both degenerate and non-degenerate cases, facilitating applications of the entangled photons.

subject: collaterals
subject: CT-Angiography

description: Objectives Identify determinants associated with variability in collateral status in patients with acute ischemic stroke and test if collateral status on CTA can be used to select patients for intra-arterial therapy (IAT). Methods Data are from the Keimyung Stroke Registry. Patients with M1 MCA occlusion on baseline CTA from 5/2004 to 7/2009 were included. All imaging was analyzed blinded to clinical information. Results Multivariable modeling identified metabolic syndrome (OR 3.22 95% CI 1.69-6.15, p<0.001), hyperuricemia (per 1 mg/dl OR 1.35 95% CI 1.12-1.62, p<0.01) and older age (per 10 years, OR 1.34 95% CI 1.02-1.77, p=0.03) as independent predictors of poor collateral status. Only patients with intermediate or good collaterals who recanalize show association with good clinical outcome. (Rate Ratio=3.8, 95% CI 1.2-12.1). Conclusions Metabolic syndrome, hyperuricemia and age are associated with poor collateral status. Patients with poor collaterals on CTA do not benefit from IAT.

description: It was noticed by Harel in [Har86] that "one can define $Σ_1^1$-complete versions of the well-known Post Correspondence Problem". We first give a complete proof of this result, showing that the infinite Post Correspondence Problem in a regular $ω$-language is $Σ_1^1$-complete, hence located beyond the arithmetical hierarchy and highly undecidable. We infer from this result that it is $Π_1^1$-complete to determine whether two given infinitary rational relations are disjoint. Then we prove that there is an amazing gap between two decision problems about $ω$-rational functions realized by finite state Büchi transducers. Indeed Prieur proved in [Pri01, Pri02] that it is decidable whether a given $ω$-rational function is continuous, while we show here that it is $Σ_1^1$-complete to determine whether a given $ω$-rational function has at least one point of continuity. Next we prove that it is $Π_1^1$-complete to determine whether the continuity set of a given $ω$-rational function is $ω$-regular. This gives the exact complexity of two problems which were shown to be undecidable in [CFS08].

description: Subthreshold depression is prevalent and increases risk of Major Depressive Disorder (MDD), though psychosocial workplace factors associated with the transition have not been explored. Using data from the Population-based Longitudinal Study on Work and Health, participants with no depression (n=2840) and subthreshold depression (n=305) were followed prospectively for two years. Subthreshold depression was measured with the Patient Health Questionnaire-9, while MDD was measured with the Composite International Diagnostic Interview-Auto 2.1. Using binomial regression modelling, those with high work to family conflict had an increased risk of 2-year transition to subthreshold depression (RRadj 1.47; 95% CI: 1.05-2.05; p=0.02) and 1-year transition to MDD (RRadj 2.88; 95% CI: 1.08-7.62; p=0.03) compared to those with low work to family conflict. Similar risk factors appear to exist for subthreshold depression and MDD. Future studies with larger sample sizes should consider multinomial transitions including outcomes of more severe depression, less severe depression, and no change.

description: We give alternative computations of the Schur multiplier of $Sp(2g,\mathbb Z/D\mathbb Z)$, when $D$ is divisible by 4 and $g\geq 4$: a first one using $K$-theory arguments based on the work of Barge and Lannes and a second one based on the Weil representations of symplectic groups arising in abelian Chern-Simons theory. We can also retrieve this way Deligne's non-residual finiteness of the universal central extension $\widetilde{Sp(2g,\mathbb Z)}$. We prove then that the image of the second homology into finite quotients of symplectic groups over a Dedekind domain of arithmetic type are torsion groups of uniformly bounded size. In contrast, quantum representations produce for every prime $p$, finite quotients of the mapping class group of genus $g\geq 3$ whose second homology image has $p$-torsion. We further derive that all central extensions of the mapping class group are residually finite and deduce that mapping class groups have Serre's property $A_2$ for trivial modules, contrary to symplectic groups. Eventually we compute the module of coinvariants $H_2(\mathfrak{sp}_{2g}(2))_{Sp(2g,\mathbb Z/2^k\mathbb Z)}=\mathbb Z/2\mathbb Z$.

description: Our research is motivated by the urgent global issue of a large population affected by retinal diseases, which are evenly distributed but underserved by specialized medical expertise, particularly in non-urban areas. Our primary objective is to bridge this healthcare gap by developing a comprehensive diagnostic system capable of accurately predicting retinal diseases solely from fundus images. However, we faced significant challenges due to limited, diverse datasets and imbalanced class distributions. To overcome these issues, we have devised innovative strategies. Our research introduces novel approaches, utilizing hybrid models combining deeper Convolutional Neural Networks (CNNs), Transformer encoders, and ensemble architectures sequentially and in parallel to classify retinal fundus images into 20 disease labels. Our overarching goal is to assess these advanced models' potential in practical applications, with a strong focus on enhancing retinal disease diagnosis accuracy across a broader spectrum of conditions. Importantly, our efforts have surpassed baseline model results, with the C-Tran ensemble model emerging as the leader, achieving a remarkable model score of 0.9166, surpassing the baseline score of 0.9. Additionally, experiments with the IEViT model showcased equally promising outcomes with improved computational efficiency. We've also demonstrated the effectiveness of dynamic patch extraction and the integration of domain knowledge in computer vision tasks. In summary, our research strives to contribute significantly to retinal disease diagnosis, addressing the critical need for accessible healthcare solutions in underserved regions while aiming for comprehensive and accurate disease prediction.

description: This study explores how education and training institutions can prepare project managers more effectively by evaluating project management education and development from the perspective of working project managers. The main objectives of this study are to describe the perceptions of project managers in the oil and gas sector regarding the skills, knowledge, and competencies necessary for success of future project managers; and to provide a practical framework to support project management education and training for developing project managers’ competency to face the complexity of projects. This study applied grounded theory, Delphi technique, and focus groups to solicit the opinions of project managers and project engineers working in the oil and gas sector in Calgary. The results of this study have provided insight into four main areas which educational institutions should consider in developing and preparing future project managers: 1) developing skills for dealing with complexity, 2) developing softer parameters of managing projects; especially interpersonal skills and leadership as opposed to just technical skills, 3) preparing project managers to be engaged within the context of real life projects, and 4) continuous skill development for project managers. The author argues that the education and training systems must do more to prepare project managers on their journey from good to great. The findings of this study reveal the importance of content, process of training, and education within the context of projects. The proposed model represents the bridge between the real world practice of project management and what should be included in project management education and training provided by educational institutions and industries.

description: Canada has the third-largest oil reserves in the world, after Saudi Arabia and Venezuela. Of Canada’s 173 billion barrels of oil reserves, 170 billion barrels are located in Alberta, and about 168 billion barrels are recoverable bitumen. Of them, 80% are recoverable by in-situ techniques where the Steam Assisted Gravity Drainage (SAGD) process is called to be the number one method of bitumen production for the next 15 years. SAGD is an energy intensive process that requires optimization. The addition of hydrocarbon solvents such as propane, butane, hexane and diluents has been explored for the last 10 years as a form to improve oil production rates. In this research, the addition of surface active agents to the steam is studied as a novel way to increase oil production rates during SAGD. The mechanism by which the surface active agents will increase bitumen production has been proposed as oil in water emulsification. It has been suggested that the emulsification process in the porous media is controlled mainly by the wettability of the rock rather than the interfacial tension and that water wet rock will lead to O/W emulsions. Laboratory experiments suggest that the addition of surface active agents to the steam increases oil production by means of O/W emulsions and that the recovery factor will be increased as well. Finally the results of a field pilot are presented and they suggest that at field scale the addition of surface active agents has the potential to increase bitumen production during SAGD operations.

description: We analyze the dynamics of a valence electron of the buckminsterfullerene molecule (C60) subjected to a circularly polarized laser field by modeling it with the motion of a classical particle in an annular billiard. We show that the phase space of the billiard model gives rise to three distinct trajectories: "Whispering gallery orbits", which only hit the outer billiard wall, "daisy orbits" which hit both billiard walls (while rotating solely clockwise or counterclockwise for all time), and orbits which only visit the downfield part of the billiard, as measured relative to the laser term. These trajectories, in general, maintain their distinct features, even as intensity is increased from 10^10 to 10^14 W*cm^-2. We attribute this robust separation of phase space to the existence of twistless tori.

description: Frugal innovation in the context of developed ecomomies has witnessed increasing interest in recent years. For Western multinational companies (MNCs) emerging markets represent promising opportunities for growth as well as the threat of new local competitors. Furthermore, economic developments drive the demand for frugal products within Western countries. Succesfully mastering this challenge means that Western MNCs have to challenge prevailing paradigms within their organizations. Literature suggests that these companies have to develop a frugal mindset to succeed in frugal innovation. However, to the best of our knowledge no publication addresses the phenomenon on an empirical basis or provides enough detail for further empirical investigation. To address this gap, we conducted a systematic literature review of 80 publications in the frugal innovation field. Building on the theroetical background of the global mindset concept, we assume that a mindset is a cognitive orientation that promotes task completion, which in turn improves task performance. Our qualitative analysis suggests that in the context of frugal innovation improved task performance would positively contribute to the following goals: (1) strategic alignment of innovating for cost conscious consumers, especially in emerging markets (2) deepening the understanding of cognitively remote customers’ needs and the context in which they live or work and (3) satisfaction of these customers’ needs with frugal solutions. Furthermore, we propose that a frugal mindset can be cultivated along the phases of (1) accepting the new realities of changing markets and competition, (2) a willingness to reconsider current approaches and (3) a willingness to take the necessary action and implement new approaches regarding the identified goals. By developing a definition based on this two-dimensional construct, we build on the theoretical foundations of a well-established mindset concept from the field of organizational behavior/strategic management and integrate various descriptions of the frugal mindset. This contribution provides a solid theoretical basis for further research.

description: Digital in-line holography is commonly used to reconstruct 3D images from 2D holograms for microscopic objects. One of the technical challenges that arise in the signal processing stage is removing the twin image that is caused by the phase-conjugate wavefront from the recorded holograms. Twin image removal is typically formulated as a non-linear inverse problem due to the irreversible scattering process when generating the hologram. Recently, end-to-end deep learning-based methods have been utilized to reconstruct the object wavefront (as a surrogate for the 3D structure of the object) directly from a single-shot in-line digital hologram. However, massive data pairs are required to train deep learning models for acceptable reconstruction precision. In contrast to typical image processing problems, well-curated datasets for in-line digital holography does not exist. Also, the trained model highly influenced by the morphological properties of the object and hence can vary for different applications. Therefore, data collection can be prohibitively cumbersome in practice as a major hindrance to using deep learning for digital holography. In this paper, we proposed a novel implementation of autoencoder-based deep learning architecture for single-shot hologram reconstruction solely based on the current sample without the need for massive datasets to train the model. The simulations results demonstrate the superior performance of the proposed method compared to the state of the art single-shot compressive digital in-line hologram reconstruction method.

description: As universities and colleges send thousands of students to study abroad each year, there are many issues and concerns as well as benefits and challenges for study abroad students and sending institutions that have been identified in current empirical studies and scholarly literature. However, little research has been done to examine international partnerships and the impacts of study abroad programs from host members’ perspectives. Designed as a qualitative research study, a case study methodology was utilized to gather in-depth information in order to gain insights into host members’ cultural perceptions and experiences interacting with study abroad students in an established international partnership between a host organization in Hong Kong and a sending institution in Canada. Guided by two overarching research questions, detailed descriptive data were collected from 16 semi-structured one-on-one interviews and three subsequent focus group meetings with a total of 23 participants at the host organization. Findings from this study highlight the complexity in international partnership development that requires each partner to understand and accept the cultural differences from their own cultural lenses. Also, this study reveals that host members' cultural perceptions have the potential to influence their decision-making and their experiences when working with others who are from a different cultural context. The implications of this study's findings not only indicate the important social, cultural and organizational factors that have influenced different stages of a partnership development, but also contribute to our understanding of how host members’ perceptions of their own and other cultural similarities and differences contribute to an increased cultural awareness and cultural sensitivity at the host organization when hosting the study abroad students.

description: The purpose of this case study was to investigate the relationship between instructional leadership and teaching practice when a specific professional discipline-based inquiry-oriented learning model was implemented in an urban elementary school. As both an instructional leader and the researcher, I conducted nine semi-structured interviews with the teachers from my school. The first research question asked, what leadership actions are most effective in supporting teachers to implement a specific professional learning model designed to support a discipline-based inquiry approach to teaching and learning? Based on the analysis of the data, three findings emerged: establishing a clear vision; instructional leader involvement in the professional learning model; and encouragement of teacher professional learning based on relational trust. A conclusion drawn was that precise focused actions of the instructional leader are effective in supporting teachers to implement a specific professional learning model designed to support a discipline-based inquiry approach to teaching and learning. The second research question asked, how does the use of a specific professional learning model designed to support a discipline-based inquiry approach to teaching and learning impact teacher professional learning? Based on the analysis of the data, three findings emerged: the learning model facilitated teacher collaboration; the learning model built teacher capacity; and the learning model accentuated teacher use of educational research and evidence to inform practice. A conclusion drawn was that the use of a specific professional learning model designed to support a discipline-based inquiry approach to teaching and learning positively impacted teacher professional learning.

description: We show that the electric dipole-dipole interaction between a pair of polar molecules undergoes an all-out transformation when superimposed by a far-off resonant optical field. The combined interaction potential becomes tunable by variation of wavelength, polarization and intensity of the optical field and its dependence on the intermolecular separation exhibits a crossover from an inverse-power to an oscillating behavior. The ability thereby offered to control molecular interactions opens up avenues toward the creation and manipulation of novel phases of ultracold polar gases among whose characteristics is a long-range entanglement of the dipoles' mutual orientation. We devised an accurate analytic model of such optical-field-dressed dipole-dipole interaction potentials, which enables a straightforward access to the optical-field parameters required for the design of intermolecular interactions in the laboratory.

We solve the linearised Hall-MHD equations in a spherical shell threaded by a homogeneous magnetic field. With the fluid/flow coupling and the Hall effect included, the magnetorotational instability and the Hall effect are both acting together. Results differ for magnetic fields aligned with the rotation axis and anti-parallel magnetic fields. For a positive alignment of the magnetic field the instability grows on a rotational time-scale for any sufficiently large magnetic Reynolds number. Even the magnetic fields which are stable against the MRI due to the magnetic diffusion are now susceptible to the shear-Hall instability. In contrast, the negative alignment places strong restrictions on the growth and the magnitude of the fields, hindering the effectiveness of the Hall-MRI. While non-axisymmetric modes of the MRI can be suppressed by strong enough rotation, there is no such restriction when the Hall effect is present. The implications for the magnitude and the topology of the magnetic field of a young neutron star may be significant.

description: Software is typically developed in incremental stages or releases. Planning releases involves deciding on which features of the software should have implementation priority. This is a complex planning process involving numerous constraints and factors, trade-offs, that often make decisions difficult. Since the success of a product depends on this plan, it is vital for planners to examine the trade-offs between different alternatives in order to make an informed choice. To support this type of decision-making, my exploration involved designing and implementing STRATOS—a visualization tool showing several software release plans simultaneously within a singular layout, helping planners understand the differences among them. Through a qualitative evaluation, I found that it enabled a range of decision-making processes, ultimately helping participants in choosing an optimal release plan. My contributions include the hybrid visualization, STRATOS, and the findings from its evaluation that implicate design for future visualizations supporting decision-making.

description: The high complexity of deep learning models is associated with the difficulty of explaining what evidence they recognize as correlating with specific disease labels. This information is critical for building trust in models and finding their biases. Until now, automated deep learning visualization solutions have identified regions of images used by classifiers, but these solutions are too coarse, too noisy, or have a limited representation of the way images can change. We propose a novel method for formulating and presenting spatial explanations of disease evidence, called deformation field interpretation with generative adversarial networks (DeFI-GAN). An adversarially trained generator produces deformation fields that modify images of diseased patients to resemble images of healthy patients. We validate the method studying chronic obstructive pulmonary disease (COPD) evidence in chest x-rays (CXRs) and Alzheimer's disease (AD) evidence in brain MRIs. When extracting disease evidence in longitudinal data, we show compelling results against a baseline producing difference maps. DeFI-GAN also highlights disease biomarkers not found by previous methods and potential biases that may help in investigations of the dataset and of the adopted learning methods.

Invasion percolation on regular trees : structure, scaling limit and ponds
Creators: name: Goodman, Jesse Alexander
Publisher: name: University of British Columbia

description: Invasion percolation is an infinite subgraph of an infinite connected graph with finite degrees, defined inductively as follows. To each edge of the underlying graph, attach a random edge weight chosen uniformly from [0,1], independently for each edge. Starting from a single vertex, a cluster is grown by adding at each step the boundary edge with least weight. Continue this process forever to obtain the invasion cluster. In the following, we consider the case where the underlying graph is a regular tree: starting from the root, each vertex has a fixed number of children. In chapter 2, we study the structure of the invasion cluster, considered as a subgraph of the underlying tree. We show that it consists of a single backbone, the unique infinite path in the cluster, together with sub-critical percolation clusters emerging at every point along the backbone. By studying the scaling properties of the sub-critical parameters, we obtain detailed results such as scaling formulas for the r-point functions, limiting Laplace transforms for the level sizes and volumes within balls, and mutual singularity compared to the incipient infinite cluster. Chapter 3 gives the scaling limit of the invasion cluster. This is a random continuous tree described by a drifted Brownian motion, with a drift that depends on a certain local time. This representation also yields a probabilistic interpretation of the level size scaling limit. Finally, chapter 4 studies the internal structure of the invasion cluster through its ponds and outlets. These are shown to grow exponentially, with law of large numbers, central limit theorem and large deviation results. Tail asymptotics for fixed ponds are also derived.

description: Graph Neural Networks have been extensively applied in the field of machine learning to find features of graphs, and recommendation systems are no exception. The ratings of users on considered items can be represented by graphs which are input for many efficient models to find out the characteristics of the users and the items. From these insights, relevant items are recommended to users. However, user's decisions on the items have varying degrees of effects on different users, and this information should be learned so as not to be lost in the process of information mining.
 In this publication, we propose to build an additional graph showing the recommended weight of an item to a target user to improve the accuracy of GNN models. Although the users' friendships were not recorded, their correlation was still evident through the commonalities in consumption behavior. We build a model WiGCN (Weighted input GCN) to describe and experiment on well-known datasets. Conclusions will be stated after comparing our results with state-of-the-art such as GCMC, NGCF and LightGCN. The source code is also included at https://github.com/trantin84/WiGCN.

description: O ensino-aprendizagem de uma língua estrangeira inclui o desenvolvimento de diferentes competências, sendo a sala de aula o espaço que permite oferecer oportunidades aos estudantes para que possam interagir num contexto real de comunicação utilizando a língua em estudo. De forma a que tal interação seja possível não se pode descurar a importância da contribuição do uso de materiais autênticos. Considera-se que o estudante ao ser exposto a materiais que permitem uma utilização real da língua, insere-se num contexto que o possibilita aproximar-se mais da realidade onde a língua estrangeira é utilizada.  No entanto, é necessário ter em consideração que se ensina e aprende na era digital e como tal deverá haver uma ponte de ligação entre suportes e recursos digitais, materiais didáticos, materiais autênticos, autenticidade e motivação. Esta ligação contribui para que exista um desenvolvimento intelectual, linguístico e sociocultural dos estudantes e igualmente o enriquecimento sociopedagógico respondendo às necessidades dos dias de hoje.

Quantifying the Preferential Direction of the Model Gradient in Adversarial Training With Projected Gradient Descent

description: Adversarial training, especially projected gradient descent (PGD), has proven to be a successful approach for improving robustness against adversarial attacks. After adversarial training, gradients of models with respect to their inputs have a preferential direction. However, the direction of alignment is not mathematically well established, making it difficult to evaluate quantitatively. We propose a novel definition of this direction as the direction of the vector pointing toward the closest point of the support of the closest inaccurate class in decision space. To evaluate the alignment with this direction after adversarial training, we apply a metric that uses generative adversarial networks to produce the smallest residual needed to change the class present in the image. We show that PGD-trained models have a higher alignment than the baseline according to our definition, that our metric presents higher alignment values than a competing metric formulation, and that enforcing this alignment increases the robustness of models.

description: In this short note we present a generating function computing the compactly supported Euler characteristic $χ_c(F(X, n), K^{\boxtimes n})$ of the configuration spaces on a topologically stratified space $X$, with $K$ a constructible complex of sheaves on $X$, and we obtain as a special case a generating function for the Euler characteristic $χ(F(X, n))$. We also recall how to use existing results to turn our computation of the Euler characteristic into a computation of the equivariant Euler characteristic.

Unraveling The Impact Of Media Use On Political Knowledge

description: Contributing to the effort to explain declining political knowledge levels among young Canadians, this thesis examines the relationship between an individual's media use and their level of political knowledge. Its core hypothesis held that reliance on online media for political information – as many young Canadians do – would result in lower levels of political knowledge. Using a multi-dimensional operationalization of political knowledge, this thesis finds that Canadians most likely to be knowledgable about domestic politics are older men with higher levels of education and income who read news from online sources. Canadians most likely to be knowledgable about international politics are men with higher levels of education who read news from online sources. Canadians most likely to be knowledgable about the practical application of government programs and policies are older women. In contrast with both public perception and a section of the literature, reliance on online news sources for political information is the strongest positive media influence on political knowledge for two of the three types of political knowledge, while age, gender and education are strong influencers on knowledge across all types.
