description: Beyond 5G (B5G) networks are poised to revolutionize connectivity by utilizing terahertz (THz) frequency bands, achieving ultra-high data rates and low latency for advanced applications such as autonomous systems, smart cities, and augmented reality. A critical component of B5G is network slicing, which enables operators to create virtualized slices tailored to specific application requirements. At the heart of this technology lies Network Slice Identification (NSI), a process that assigns traffic flows to the appropriate slice based on their characteristics. This thesis investigates machine learning and transfer learning techniques to enhance NSI, addressing challenges such as limited labelled data, robustness under perturbation, and adaptability across systems. The research evaluates five primary research issues: (1) the comparative study of supervised, unsupervised, and semi-supervised learning approaches for NSI; (2) the impact of feature selection, dimensionality reduction, and data sampling on model performance; (3) the benefits of multi-metric evaluation methods for clustering models; (4) the use of transfer learning to adapt pre-trained NSI models efficiently on a new system; and (5) the resilience of these models under data perturbation denoting network fluctuations and noise. Key findings demonstrate that supervised learning using Random Forest Classifier achieves perfect accuracy when leveraging network characteristics, while semi-supervised learning with self-training also achieves high accuracy across varying proportions of labelled data. Unsupervised learning using K-Means clustering requires significant optimization techniques, such as undersampling and dimensionality reduction, to achieve comparable performance. The study highlights the importance of focusing on relevant features and balancing datasets to enhance model performance. Additionally, transfer learning proves to be a robust approach for adapting pre-trained models across systems with minimal retraining, achieving significant improvements in validation accuracy and maintaining competitive training latency. Furthermore, transfer learning demonstrates superior resilience under noisy conditions compared to other methods, making it ideal for dynamic 5G environments. This thesis contributes novel insights into NSI modelling by integrating feature selection, multi-metric evaluation frameworks, and transfer learning strategies. The findings provide a foundation for robust and scalable NSI solutions in rapidly evolving B5G networks. By addressing key challenges in NSI through innovative machine learning approaches, this research advances the state-of-the-art in network slicing technologies and offers practical solutions for real-world deployment in next-generation networks.

description: Materials used in solar receivers are exposed to high stresses, i.e. high temperatures (up to 1000° C in current solar towers, 1400°C for next generations, resp. 350 and 700°C for linear concentrators); high spatial thermal gradients (mainly due to the non-uniform concentrated solar irradiation) and high dynamic thermal gradient (e.g. fast during cloud passing or slow due to the daily cycling from dawn till dusk).

Due to these very severe conditions, the materials degrade over time, their properties change, leading to reduced performance and ultimately to the failure and the ruin of the associated structure, increasing the cost of operation. Accurate in-situ measurements are required in order to select the materials (development and qualification stages with SFERA-III Research Infrastructures) or improve their lifetime and the optimal operation of a solar plant (commercial stage). However, the health evaluation of solar receivers is typically observed subjectively during downtime at night, or by sampling parts sent for laboratory analysis (MEB, XRD, chemistry...).

Thanks to recent unique advances, it can be envisaged to be determined objectively in-situ using acoustic techniques, as commonly used in infrastructure buildings such as bridges, sky-scrapers, dams or nuclear power plants. A subset of these techniques has been successfully tested and derived for concentrated solar conditions within SFERA-II as worldwide pioneers using a research solar furnace, carrying on much further the SFERA-I developments about accelerated ageing setups and protocols to assess receivers resistance. Yet enhancements of this work are required in order to further interpret the observed data into broad degradation mechanisms (delaminations, cracks...) which will allow determining the actual remaining margin of the receiver of demonstration or commercial solar plants.

This report presents the assessment and verification of the feasibility of the location of damaging events on a real solar receiver while deploying convenient and simple sensor location. These first steps verification were operated at room temperature and successfully demonstrated the potential of both the location and the identification of impending solar receivers damage thanks to a single acoustic ultrasonic sensor and data processing.

description: We present an invertible map between correlations in any bipartite Bell scenario and behaviours in a family of contextuality scenarios. The map takes local, quantum and non-signalling correlations to non-contextual, quantum and contextual behaviours, respectively. Consequently, we find that the membership problem of the set of quantum contextual behaviours is undecidable, the set cannot be fully realised via finite dimensional quantum systems and is not closed. Finally, we show that neither this set nor its closure is the limit of a sequence of computable supersets, due to the result MIP*=RE.

description: The environmental challenges posed by the surface erosion of Calgary's gravel back lanes necessitate a sustainable approach to their surface treatment. Back lanes, primarily used as utilitarian corridors for vehicular access and waste collection, present design and planning opportunities that extend beyond proposing an optimal paving option. These opportunities could transform the role of back lanes in Calgary from service corridors to residential alleys by creating a “laneway urbanism”, contributing to the city's overall sustainability and resilience particularly in the Post World War II suburbs. This thesis proposes a “vitalization” framework for back lanes in Calgary’s postwar suburbs, consisting of strategies for short-term and long-term changes that would collectively constitute a laneway urbanism as the big picture. The short-term scenario focuses on finding an optimal paving solution and promoting ecological systems through greening underutilized edges, connecting to a long-term scenario that emphasizes densification through the development of backyard suites, as well as the integration of renewable energy and the exploration of new waste collection systems in the alleyscape. Adoption of these strategies within the proposed framework stems from the significance of tackling broader urban issues. Naturalization would promote ecological and social health while enhancing resilience to potential climate change impacts. Densification through developing backyard suites would alleviate some of the negative consequences of low-density urban sprawl, particularly by enabling increased housing supply and housing choices to accommodate population growth. Infill development also aligns with the City of Calgary’s intention to densify the single-family zoning districts through the recently approved blanket rezoning proposal that allows for alternative types of low-density housing in these areas besides single detached dwellings. Integrating renewable energy systems into back lane vitalization also aligns with broader energy transition goals that are pursued nationwide through initiatives such as Canada Greener Homes . In essence, this study proposes a holistic framework that integrates environmental, social, economic, and aesthetic aspects for a sustainable vitalization of back lanes. It envisions back lanes as "new front streets", providing a roadmap for building resilient and sustainable back lanes as a means for a laneway urbanism to emerge.

description: Microgrids are an excellent solution to integrate modern power generation and consumption with legacy infrastructure. Their flexibility and adaptability make them ideal for several applications combining Renewable Energy Sources and Energy Storage Systems, interfacing them with traditional generation systems. Nonetheless, the stability of these can be compromised under the presence of Constant Power Load (CPL) behavior, given by tightly regulated converters connecting AC and DC loads to a DC bus. This thesis presents an innovative nonlinear estimator used to identify the CPL and resistive power consumption components, and two estimation based controllers for Boost converters regulating the DC bus voltage. These controllers leverage the information provided by the system identification method and enhance the Microgrid stability by increasing the power range of operation. The controllers combine non-linear control techniques with the traditional PI control structure, in which the proportional and integral gains vary according to the estimated load power, allowing it to maintain constant dynamics at all operating conditions. The analysis incorporates comprehensive models that characterize the dynamic behavior of the Microgrid connected Boost converter, validating the stable operation under different loading conditions through simulation and experimental results. The proposed methods show low computation complexity and are suitable for implementation on industry-standard microcontrollers, making them flexible to be implemented in low-cost power platforms.

description: We calculate the charge balance function of the bulk quark system before hadronization and those for the directly produced and the final hadron system in high energy heavy ion collisions. We use the covariance coefficient to describe the strength of the correlation between the momentum of the quark and that of the anti-quark if they are produced in a pair and fix the parameter by comparing the results for hadrons with the available data. We study the hadronization effects and decay contributions by comparing the results for hadrons with those for the bulk quark system. Our results show that while hadronization via quark combination mechanism slightly increases the width of the charge balance functions, it preserves the main features of these functions such as the longitudinal boost invariance and scaling properties in rapidity space. The influence from resonance decays on the width of the balance function is more significant but it does not destroy its boost invariance and scaling properties in rapidity space either. The balance functions in azimuthal direction are also presented.

description: Consider a population of $N$ individuals, each of them carrying a type in $\mathbb N_0$. The population evolves according to a Moran dynamics with selection and mutation, where an individual of type $k$ has the same selective advantage over all individuals with type $k' > k$, and type $k$ mutates to type $k+1$ at a constant rate. This model is thus a variation of the classical Muller's ratchet: there the selective advantage is proportional to $k'-k$. For a regime of selection strength and mutation rates which is between the regimes of weak and strong selection/mutation, we obtain the asymptotic rate of the {\em click times} of the ratchet (i.e. the times at which the hitherto minimal (`best') type in the population is lost), and reveal the quasi-stationary type frequency profile between clicks. The large population limit of this profile is characterized as the normalized attractor of a ``dual'' hierarchical multitype logistic system, and also via the distribution of the final minimal displacement in a branching random walk with one-sided steps. An important role in the proofs is played by a graphical representation of the model, both forward and backward in time, and a central tool is the ancestral selection graph decorated by mutations.

description: In this paper I propose to reconsider theories of diegetic space that rely on explicit framing (i.e., "two people walk into a room" or "in Spain"). Rather than looking for maps, I define space in terms of lexical categories denoting objects. The emphasis on objects leads to a method for literary archaeology, informed by cognitive theory and anthropology. If the universe is made of atoms, a fictional world is also made up of atomic relationships that form basic, stable configurations, or what I call narratological primes. I construct several such basic spatial buildings blocks here—diegetic density and clutter distance. Their application to a well-explored body of nineteenth-century novels challenges several long-standing historical intuitions related to the development of material culture in the nineteenth century.

description: Children with intestinal failure (IF) are at high-risk for different types of anemia, including iron deficiency anemia (IDA), anemia of inflammation (AI) and mixed IDA/AI. Data on the prevalence and underlying contributors to the types of anemia in the pediatric IF population is limited. Therefore, the aim of this thesis was to examine the prevalence and contributions of the various types of anemia in children with IF and identify factors associated with these anemias. A 10-year retrospective, multicenter study of pediatric IF patients managed by three separate intestinal rehabilitation programs (IRPs) in Canada was conducted. Anemia was defined by age-specific hemoglobin values, and anemia types were classified using a combination of hematologic measures and iron indices. Univariable regression analysis was performed to evaluate for demographic and clinical factors associated with anemia and anemia types. Among ninety children with IF, the period prevalence of anemia was 83% [75/90], with 76% [55/72] of children experiencing chronic anemia, defined as anemia on ≥2 annual hemoglobin measurements. AI (44%) [40/90] and mixed IDA/AI (36%) [32/90] were more prevalent than IDA (17%) [15/90]; 26% [19/90] children developed >1 type of anemia over time, and 84% [191/227] of anemic hemoglobin measurements occurred while receiving iron supplementation, oral or in parenteral nutrition (PN). The prevalence of mixed IDA/AI was higher at 2 IRPs that did not have access to iron-supplemented PN (75% vs 9%; p<0.001), as was small intestine bacterial overgrowth (SIBO) (58% vs 28%; p=0.004) and gastrointestinal bleeding (39% vs 15%; p=0.001). Children receiving iron-supplemented PN had lower odds of mixed IDA/AI compared to no anemia (OR 0.06, p<0.001), while oral iron supplementation was associated with an increased odds of mixed IDA/AI compared to no anemia (OR 3.40, p=.01). This study demonstrated a high prevalence of anemia in children with IF, specifically mixed IDA/AI and AI. This anemia is often chronic and dynamic with evolving anemia types. Our results suggest that mode of iron supplementation may impact IF-associated complications and anemia types. Future studies exploring the complex interactions between the gut microbiome, mode of iron supplementation and inflammation on anemia in pediatric IF are needed.

description: A substantial proportion of student loan borrowers default on their repayment within 12 years of initial college entry. Default rates vary dramatically by race/ethnicity and institution sector: Black entrants and for-profit entrants experience default at much higher rates than others. This Brookings Institution report examines whether these disparities can be explained by other factors and what happens after a default.

Differences in student and family background characteristics, including family income and wealth, can account for about half of the Black-White gap in defaults. But even accounting for differences in degree attainment, college GPA, and post-college income and employment cannot fully explain the gap, which remains large and statistically significant at 11 percentage points in the most complete model.

Similarly, differences in student and family background characteristics can account for nearly half of the gap in default rates between borrowers from for-profits and public two-year colleges. But the gap is not fully explained by differences in attainment, employment, or earnings. Entering a for-profit is associated with a 10-point higher rate of default, even after accounting for everything else in the model.

Fifty-four percent of all defaulters resolved at least one of their defaulted loans via rehabilitation, consolidation, paying in full, or having a loan discharged. At least 14 percent emerged from default and re-enrolled in school. While there is no Black-White difference in resolution rates, White defaulters are more likely to rehabilitate defaulted loans, while Black defaulters are more likely to consolidate. Similarly, defaulters from for-profit institutions were more likely to consolidate and less likely to rehabilitate a defaulted loan than defaulters from public two-year institutions.

description: Quantum mechanics is an extremely successful theory that agrees with every experiment. However, the principle of linear superposition, a central tenet of the theory, apparently contradicts a commonplace observation: macroscopic objects are never found in a linear superposition of position states. Moreover, the theory does not really explain as to why during a quantum measurement, deterministic evolution is replaced by probabilistic evolution, whose random outcomes obey the Born probability rule. In this article we review an experimentally falsifiable phenomenological proposal, known as Continuous Spontaneous Collapse: a stochastic non-linear modification of the Schrödinger equation, which resolves these problems, while giving the same experimental results as quantum theory in the microscopic regime. Two underlying theories for this phenomenology are reviewed: Trace Dynamics, and gravity induced collapse. As one approaches the macroscopic scale, the predictions of this proposal begin to differ appreciably from those of quantum theory, and are being confronted by ongoing laboratory experiments that include molecular interferometry and optomechanics. These experiments, which essentially test the validity of linear superposition for large systems, are reviewed here, and their technical challenges, current results, and future prospects summarized. We conclude that it is likely that over the next two decades or so, these experiments can verify or rule out the proposed stochastic modification of quantum theory.

description: Cyanobacteria have been proposed as a promising resource for the next generation of industrial biotechnologies to produce high-value food ingredients and bioactive compounds. As photosynthetic microorganisms, they require only sunlight, carbon dioxide, water, and essential nutrients to thrive. Cyanobacteria are remarkable for growing in non-arable land, avoiding competition with conventional crops. They can also be cultivated in seawater and wastewater, conserving precious freshwater resources and making them ideal for industrial applications in water-scarce regions. Their versatility and potential for large-scale, sustainable bioproduction make cyanobacteria key players in developing eco-friendly biotechnologies to address global challenges in food and chemicals. However, the scale-up of these biotechnologies faces significant challenges. One major challenge is cultivation, which includes carbon supply, high water requirements, and nutrient availability. This thesis explores strategies to address these challenges by investigating the reuse and recycling of waste products in a closed-loop cultivation system. The study focuses on cultivating a cyanobacterial consortium under high pH and alkalinity conditions, beginning with examining nutrient management and the reuse of spent medium (Chapter 2). The results show that the spent medium contains many essential nutrients for cultivation, but requires replenishment with nitrogen and bicarbonate before it can be reused effectively. Additionally, the spent medium can be reused for several cycles without negatively impacting biomass growth, provided such replenishment is implemented. This approach of reusing spent media reduces water and nutrient demands over multiple cycles, offering a sustainable cultivation method. Chapter 3 delves into the microbial ecology and biogeochemistry of sediments in Canadian soda lakes, the natural habitat of the cyanobacterial consortium. This chapter highlights unique microbial adaptations to extreme environments and provides insights into nutrient cycling and ecological resilience. Chapter 4 analyzes waste products from anaerobic digestion, revealing their potential as nutrient sources while also uncovering contaminants such as 2,4-di-tert-butylphenol, which may contribute to culture crashes. These findings underscore the need for pretreatment strategies to recycle anaerobic digestion waste in the closed-loop system.

description: We report a first case study of the phase diagram of 2+1 flavor strongly interacting matter in $β-$equilibrium, using the Polyakov$-$Nambu$-$Jona-Lasinio model. Physical characteristics of relevant thermodynamic observables have been discussed. A comparative analysis with the corresponding observables in the Nambu-Jona-Lasinio model is presented. We find distinct differences between the models in terms of a number of thermodynamic quantities like the speed of sound, specific heat, various number densities as well as entropy. The present study is expected to give us a better insight into the role that the superdense matter created in heavy ion collision experiments play in our understanding of the properties of matter inside the core of supermassive stars in the Universe.

The branching mechanism in consideration is defined by the mixture of logarithmic distributions on the nonnegative integers. The purpose of the present paper is to prove that in this case the random number of particles X(t) alive at time t>0 follows the shifted extended Sibuya distribution, with parameters depending on the time $t>0$. The conditional limit probability is exactly the logarithmic series distribution supported by the positive integers.

description: We study the possible constraints on non-standard interaction(NSIs) in a model independent way by considering the recent results from T2K and Daya Bay neutrino oscillations experiments. Using perturbation method we present generic formulas (suitable for T2K baseline and for large $θ_{13}$ as evident from Daya Bay) for the probability of oscillation for $ν_μ\rightarrow ν_e$, taking into account NSIs at source ($ε^s$), detector ($ε^d$) and during propagation ($ε^m$) of neutrinos through matter. Two separate cases of perturbation with small (slightly large) NSI ($ε_{αβ}^m \sim 0.03(0.18)$) are discussed in detail. Using various possible presently allowed NSI values we reanalyze numerically the $θ_{13} - δ$ allowed region given by recent T2K experimental data. We obtain model independent constraints on NSIs in the $δ-ε_{αβ}^m$ plane using the $θ_{13}$ value as measured by Daya Bay, where $δ$ is the CP violating phase. Depending on $δ$ values significant constraints on $ε_{eτ}$ and $ε_{ττ}$, in particular, are possible for both hierarchies of neutrino masses. Corresponding to T2K's 66% confidence level result, the constraints on $ε_{ττ}$ is shown to be independent of any $δ$ value.

description: A rapidly growing number of higher education institutions nationwide are implementing advising technologies—including education planning, counseling and coaching, and risk targeting technologies—to help students plan their academic paths and stay on track to graduation. Research suggests that these technologies may improve support for students if institutions also adopt advising structures and processes that leverage technology to provide a more intensive and personalized advising experience.

This report from CCRC and MDRC describes how the University of North Carolina, Charlotte; California State University, Fresno; and Montgomery County Community College in Pennsylvania are approaching comprehensive, technology-based advising reforms, presenting detailed examples of their new advising practices, outreach methods, and messages to students. Based on observations of the advising redesigns at these three institutions, the report provides insights and ideas for other institutions seeking to redesign their advising practices around new technologies.

description: We investigate string or branelike solutions for four-dimensional vacuum Einstein equations in the presence of cosmological constant. For the case of negative cosmological constant, the Banados-Teitelboim-Zanelli black string is the only warped stringlike solution. The general solutions for nonwarped branelike configurations are found and they are characterized by the Arnowitt-Deser-Misner mass density and two tensions. Interestingly, the sum of these tensions is equal to the minus of the mass density. Other than the well-known black string and soliton spacetimes, all the static solutions possess naked singularities. The time-dependent solutions can be regarded as the anti-de Sitter extension of the well-known Kasner solutions. The speciality of those static regular solutions and the implication of singular solutions are also discussed in the context of cylindrical matter collapse. For the case of positive cosmological constant, the Kasner-de Sitter spacetime appears as time-dependent solutions and all static solutions are found to be naked singular.

description: Infectious disease models are important tools for informing public health policy and gaining a better understanding of disease transmission dynamics. For them to accomplish these goals effectively it is important that models accurately represent the mechanisms that drive disease spread. During many epidemics, changing human behaviour is a driving force behind shifts in transmission patterns. In times of perceived higher risk people will often adopt protective behaviour changes to attempt to mitigate the impact of the disease on themselves or others in their community. These behaviour changes are typically complex, not well understood, and difficult to quantify. For these reasons behaviour change is challenging to incorporate into an infectious disease model. However, ignoring its effect can lead to inaccurate estimates of epidemic metrics and misleading forecasts of future trajectories. It is therefore important to develop methods that allow for the effect of behaviour changes to be adequately captured. We propose a flexible framework for incorporating epidemic-driven behaviour change into an individual-level model (ILM), which models individual probability of infection over time as a function of individual-level covariates. Focusing on spatially-based ILMs, we consider four potential so-called “alarm functions” for relating prevalence to population protective behaviour changes. We explore the impact of allowing behaviour changes to affect different model components, and of misspecifying the form of the alarm function or model structure. Methods are applied to a data set of the 2001 foot and mouth disease epidemic amongst livestock in the United Kingdom. Next we outline a framework to allow dynamic time-dependent adherence to behaviour changes in a population-averaged framework. Four adherence functions are proposed and investigated through simulation studies. These “dynamic behaviour change models” are then used to analyse four waves of COVID-19 in Calgary, Alberta. Finally, we conduct a data analysis of two waves of COVID-19 in four locations throughout Canada and the United States. We compare models that have either an epidemic history- or behaviour proxy covariate-driven behaviour change effect, or a behaviour change effect that is informed by both epidemic history and an external covariate.
Sqrt{shat}_{min} resurrected

description: We discuss the use of the variable sqrt{shat}_{min}, which has been proposed in order to measure the hard scale of a multi parton final state event using inclusive quantities only, on a SUSY data sample for a 14 TeV LHC. In its original version, where this variable was proposed on calorimeter level, the direct correlation to the hard scattering scale does not survive when effects from soft physics are taken into account. We here show that when using reconstructed objects instead of calorimeter energy and momenta as input, we manage to actually recover this correlation for the parameter point considered here. We furthermore discuss the effect of including W + jets and t tbar+jets background in our analysis and the use of sqrt{shat}_{min} for the suppression of SM induced background in new physics searches.

description: Alzheimer’s disease (AD) has been associated with changes in driving behaviours and navigational deficits, often emerging in early stages. The ATN framework defines AD pathology through beta-amyloid (A), tau (T), and neurodegeneration (N) biomarkers, which can manifest before clinical symptoms. In this study, we designed and calculated several metrics to quantify navigation and driving behaviours to understand how they relate to ATN biomarkers in individuals without cognitive impairment. Cerebral spinal fluid biomarker (CSF) concentrations and GPS driving data were collected from 125 cognitively normal participants between ages 65 and 85 enrolled in a longitudinal study at Washington University School of Medicine. Participants were categorized as biomarker-negative (-) or biomarker-positive (+) according to CSF concentrations of A, T, and N biomarkers. Several metrics were designed to capture temporal, spatial, and navigational aspects of driving. Temporal metrics included idle time at the start and end of trips to examine driver hesitation. Spatial metrics included distance travelled and life space (distance from home). Navigational metrics included turn counts, route straightness and route complexity, route diversity (proportion of unique routes), most common route concentration (frequency of most travelled route), and comparisons of actual versus time-optimized routes to evaluate navigational decision-making. Exploratory cross-sectional analyses over one and longitudinal analyses assessed trends over two years revealed notable relationships between the metrics and ATN biomarkers. N+ participants may have lower idle time at the start of a trip and lower route diversity than N- participants. Route diversity may also be reduced for T+ participants compared to T- participants. Complexity was higher for A+ participants after accounting for age, though it decreased with age. Idle time at the start of a trip increased with time for T- and N- participants but not T+ or N+ participants. Additionally, both straightness and the ratio of the actual route straightness to the optimized route straightness increased over time for N+ participants but not N- participants. These findings highlight the utility of the metrics in capturing subtle changes in driving and navigation behaviours and emphasize their potential as early markers of AD-related changes.
