description: We address the question whether a violation of Lorentz symmetry can explain the tension between the measurement and the Standard-Model prediction of the anomalous magnetic moment of the muon ($(g-2)_μ$) and whether it can significantly impact the one of the electron ($(g-2)_{e}$). While anisotropic Lorentz-violating effects are, in general, expected to produce sidereal oscillations in observables, isotropic Lorentz violation in the charged-lepton sector could feed into $(g-2)_{e,μ}$. However, we find that this type of Lorentz violation, parametrised via a dim-4 field operator of the Standard-Model Extension (SME), is already strongly constrained by the absence of vacuum Čerenkov radiation and photon decay. In particular, the observations of very-high-energetic astrophysical photons at LHAASO and of high-energetic electrons (muons) by the LHC (IceCube) place the most stringent two-sided bounds on the relevant SME coefficients $\overset{\circ}{c}{}^{(e)}$ ($\overset{\circ}{c}{}^{(μ)}$). Therefore, any explanation of the tension in $(g-2)_μ$ via isotropic Lorentz violation of the minimal spin-degenerate SME is excluded, and the possible size of its impact on $(g-2)_{e}$ is very limited.

description: We consider the Seiberg-Witten solution of pure $\mathcal{N} =2$ gauge theory in four dimensions, with gauge group $SU(N)$. A simple exact series expansion for the dependence of the $2 (N-1)$ Seiberg-Witten periods $a_I(u), a_{DI}(u)$ on the $N-1$ Coulomb-branch moduli $u_n$ is obtained around the $\mathbb{Z}_{2N}$-symmetric point of the Coulomb branch, where all $u_n$ vanish. This generalizes earlier results for $N=2$ in terms of hypergeometric functions, and for $N=3$ in terms of Appell functions. Using these and other analytical results, combined with numerical computations, we explore the global structure of the Kähler potential $K = \frac{1}{2π} \sum_I \text{Im}(\bar a_I a_{DI})$, which is single valued on the Coulomb branch. Evidence is presented that $K$ is a convex function, with a unique minimum at the $\mathbb{Z}_{2N}$-symmetric point. Finally, we explore candidate walls of marginal stability in the vicinity of this point, and their relation to the surface of vanishing Kähler potential.

Novel Approach for Converter Systems Modeling, Design, and Comparisons
Creators: Saghafi, Ali
Publisher: name: University of Alberta Library
Year: 2023

In the wake of increasing demand for DC-DC converters with high power density and high efficiency, the design of modern power converters has evolved into a multi-objective optimization problem with multiple uncertainties associated with parameter and component selection. The iterative design procedure, manual component selection, and the diverse nature of passive and active components complicate optimum DC-DC converter design and comparison. Existing methods suffer from excessive computation time, inaccurate component modeling, and inadequate design variables, resulting in sub-optimal solutions.

In this thesis, the design of a non-isolated DC-DC power converter is formulated as a multi-objective optimization problem, which seeks to reduce the total converter volume and power loss. A new component modeling method is proposed, that incorporates the impact of major converter components, including the inductor, capacitor, MOSFET, and heat sink, to overcome the uphill challenge of automating the optimization process. This model allows for the mathematical expression of design objectives in terms of technology-specific parameters and converter operating conditions without selecting or assuming specific components. After the optimal solutions are determined, all components can be selected in one step at the end of the process.

Experimental and data-driven analyses are conducted to confirm the validity of the component modeling and design method. The automated optimum design procedure is then used to study the effects of various parameters on design objectives and to compare the efficiency and power density of different converter topologies for particular applications.

description: In observational studies, the causal effect of a treatment may be confounded with variables that are related to both the treatment and the outcome of interest. In order to identify a causal effect, such studies often rely on the unconfoundedness assumption, i.e., that all confounding variables are observed. The choice of covariates to control for, which is primarily based on subject matter knowledge, may result in a large covariate vector in the attempt to ensure that unconfoundedness holds. However, including redundant covariates can affect bias and efficiency of nonparametric causal effect estimators, e.g., due to the curse of dimensionality. Data-driven algorithms for the selection of sufficient covariate subsets are investigated. Under the assumption of unconfoundedness the algorithms search for minimal subsets of the covariate vector. Based, e.g., on the framework of sufficient dimension reduction or kernel smoothing, the algorithms perform a backward elimination procedure assessing the significance of each covariate. Their performance is evaluated in simulations and an application using data from the Swedish Childhood Diabetes Register is also presented.

description: We present the first public release of our Bayesian inference tool, Bayes-X, for the analysis of X-ray observations of galaxy clusters. We illustrate the use of Bayes-X by analysing a set of four simulated clusters at z=0.2-0.9 as they would be observed by a Chandra-like X-ray observatory. In both the simulations and the analysis pipeline we assume that the dark matter density follows a spherically-symmetric Navarro, Frenk and White (NFW) profile and that the gas pressure is described by a generalised NFW (GNFW) profile. We then perform four sets of analyses. By numerically exploring the joint probability distribution of the cluster parameters given simulated Chandra-like data, we show that the model and analysis technique can robustly return the simulated cluster input quantities, constrain the cluster physical parameters and reveal the degeneracies among the model parameters and cluster physical parameters. We then analyse Chandra data on the nearby cluster, A262, and derive the cluster physical profiles. To illustrate the performance of the Bayesian model selection, we also carried out analyses assuming an Einasto profile for the matter density and calculated the Bayes factor. The results of the model selection analyses for the simulated data favour the NFW model as expected. However, we find that the Einasto profile is preferred in the analysis of A262. The Bayes-X software, which is implemented in Fortran 90, is available at http://www.mrao.cam.ac.uk/facilities/software/bayesx/.

Investigating the role of the base mismatches within the hairpin ends of vaccinia virus genome in viral life cycle
Creators: Shenouda, Mira M.M.
Publisher: name: University of Alberta Library
Year: 2023

The genome of poxviruses consists of a double-stranded DNA that is flanked by two AT-rich hairpin ends encoding mismatched nucleotides. These mismatched structures are composed of incompletely base paired regions forming extra-helical loops. Though the functionality of these mismatches has not yet been firmly established, their presence is conserved among all completely sequenced poxviruses. Thus, the focus of this project has been to study the function(s) of the hairpin ends and the mismatches within them.

These ends of the poxvirus genome have been very difficult to study using conventional recombination-based genome editing methods. Using synthetic genome assembly methods, I have modified these ends to remove some of the mismatches. We showed that simply altering the sequence of the 70bp hairpin ends attenuates the virus. Specifically, our results showed that removing most of these mismatches suppressed the growth of the virus. However, these modifications do not affect viral genome replication nor the resolution reactions that generate monomeric genomes. The most penetrant of these telomeric mutations caused about a 12-fold increase in the proportion of defective viral particles. However, these defective particles still packaged DNA. Finally, our microscopy data suggests that altering the hairpin ends affects virion maturation, causing the accumulation of defective immature virions in infected cells. We also showed that these forms of mutant viruses exhibited decreased virulence in immunocompromised mice. However, these attenuated strains can still be used as vaccines to protect against a lethal challenge in immunocompetent animals.

description: Using Lipman's results on resolution of two-dimensional singularities, we provide a form of resolution of singularities in codimension two for reduced quasi-excellent schemes. We deduce that operations of degree less than two on algebraic cycles are characterised by their values on classes of regular schemes. We provide several applications of this "detection principle", when the base is an arbitrary regular excellent scheme: integrality of the Chern character in codimension less than three, existence of weak forms of the second and third Steenrod squares, Adem relation for the first Steenrod square, commutativity and Poincaré duality for bivariant Chow groups in small degrees. We also provide an application to the possible values of the Witt indices of non-degenerate quadratic forms in characteristic two.

description: The ability to load ultracold atoms at a well-defined energy in a disordered potential is a crucial tool to study quantum transport, and in particular Anderson localization. In this paper, we present a new method for achieving that goal by rf transfer of atoms of an atomic Bose-Einstein condensate from a disorder insensitive state to a disorder sensitive state. It is based on a bichromatic laser speckle pattern, produced by two lasers whose frequencies are chosen so that their light-shifts cancel each other in the first state and add-up in the second state. Moreover, the spontaneous scattering rate in the disorder-sensitive state is low enough to allow for long observation times of quantum transport in that state. We theoretically and experimentally study the characteristics of the resulting potential.

Nanodelivery of Novel Inhibitors of ERCC1/XPF for sensitizing colorectal cancer cell to platinum drugs
Creators: Mehinrad, Parnian
Publisher: name: University of Alberta Library
Year: 2023

This project's long-term goal is to increase the efficacy of genotoxic therapeutics through thesensitization of cells to DNA-damaging therapy ahead of the treatment. The focus of this projectwas on the enhancement of platinum-based chemotherapeutics in colorectal cancer usingcolorectal cancer cell lines as models of the disease. For this purpose e, novel inhibitor of a DNArepair enzyme involved in the repair of DNA caused by platinum-based chemotherapeutics, i.e.,small molecule inhibitors of ERCC1-XPF heterodimerization, namely A4 and pyronaridine wereused. To reduce the systemic effect of ERCC1-XPF inhibitors, that can lead to the sensitization ofnormal cells as well as cancer cells to DNA-damaging chemotherapeutics nano delivery systemsof A4 and pyronaridine were also developed. Inhibition of ERCC1/XPF, a heterodimeric enzymecomplex with endonuclease activity that participates in the repair of DNA inter-and intra-strandcrosslinks, by A4, pyronaridine, and their nano-formulations was hypothesized to make cellssensitive to DNA damage by platinum-based chemotherapeutics. The results of our studies ledto the development of optimum polymer and lipid-based nano-formulations for delivery of A4and pyronaridine, respectively, showing maximum encapsulation efficiency, <50 % drug releasewithin 24 hrs, and average diameter of < 150 nm. Free and particularly encapsulated inhibitorsof ERCC1/XPF were able to sensitize colorectal cancer cells to the cytotoxic effects of platinumbased chemotherapeutics under study at specific dose ratios. The sensitizing effect of ERCC1/XPFinhibitors and their encapsulated counterparts was more noticeable for carboplatin

description: We consider $W^\pm Z$ production in hadronic collisions and present high-precision predictions in QCD and electroweak (EW) perturbation theory matched to parton showers. To this end, we match next-to-next-to-leading order QCD corrections to parton showers using the MiNNLO$_{\rm PS}$ method and consistently combine them with next-to-leading order EW corrections matched to parton showers. This is the first time such accuracy in the event generation is achieved for any collider process, and we study in detail the impact of different choices in the combination of QCD and EW corrections as well as QCD and QED showers. Spin correlations, interferences and off-shell effects are retained by considering the full leptonic processes $pp \to \ell^+\ell^-\ell'^\pm ν_\ell'$ with $\ell'\neq\ell$ and $\ell'=\ell$ without approximations, and the matching to QED radiation is performed preserving the resonance structure of the process. We find that NNLO QCD predictions including QCD and QED shower effects provide a very good approximation in the bulk-region of the phase space, while EW effects become increasingly important in the high-energy tails of kinematic distributions. Our default predictions are in excellent agreement with recent ATLAS data.

A Novel Approach to Delay Thermal and Autoxidative Fouling Caused by Aromatics in Heavy oil and Petrochemicals Using Tetrahydrofurfuryl Alcohol
Creators: Gomaa, Ahmed
Publisher: name: University of Alberta Library
Year: 2023

Tetrahydrofurfuryl alcohol (THFA) is a widely used solvent. It is a preferred solvent since it is derived from biomass. Multiple patents have reported that adding THFA during heavy oil processing improves the efficiency of the process and increases the yield. One patent for instance reported that adding THFA in a ratio of about 3wt% to feedstock decreased coke formed and increased the liquid yield of the condensable volatiles of some bitumen samples during upgrading. Another patent reported that the addition of THFA during the re-refining of oil greatly improved the efficiency of the process. The patents have yet to report anything on how THFA improves the process. Currently, there is not much literature on the use of THFA in the processing of petrochemicals. In this work, THFA was tested for its effect on the accelerated fouling of different oil samples. THFA was found to improve the autoxidative stability of the oil samples greatly reducing the amount of insolubles formed. THFA was also found to soften existing solids lightening their color and changing their physical nature to gums. THFA effect was found to be proportional to the percentage aromatics present in the oil samples. THFA was further tested on the fouling system of indene. Indene was heated with THFA at different concentration at different temperatures. It was found that THFA delayed the thermal oxidation of indene delaying the formation of carbonyl and hydroxyl groups. THFA's effect was persistent up to 230 °C. An ether compound was also tested. The ether showed similar trends to THFA; however, it was not as effective, failing to prevent oxidation at temperatures of 200 °C and above. THFA was also found to have a permanent effect on the solids formed during oxidation resulting in the formation of softer, yet denser gums than solids. THFA was found to have maximum efficiency if added in a ratio of 1:1 weight percent to the indene.
A General Framework of Optimal Stochastic Optimization with Dependent Data: Multiple Optimality Guarantee, Sample Complexity, and Tractability
Creators: Pan, Bo
Publisher: name: University of Alberta Library
Year: 2023

We consider stochastic optimization in settings where the distribution of unknown parameters is observable only through finitely dependent training samples. Using the Sample Averaging Approximation ({SAA}), we specifically study the data-driven procedure in which, instead of receiving samples from the underly probability measure, the samples are taken along a single trajectory of a stochastic process $P$, where $P$ converge to the stationary distribution which we optimize, and construct optimal decisions. In this paper, we leverage measure concentration results and information theory to show that {SAA} retains strong asymptotic consistency and finite-sample performance guarantees provided that the source of randomness is suitably mixing. We moreover establish the optimal asymptotic normality results and shows the sample complexity of the {SAA} is bounded in terms of Empirical Rademacher Complexity. These results are adaptive to a natural class of optimization problems under a variety of structural assumptions. The numerical complexity of objectives, such as optimizing a (possibly constrained) sum of smooth and nonsmooth functions, can be handled efficiently by stochastic operator-splitting schemes under mild conditions. We establish strong convergence guarantees for these schemes. The results of this work have implications for stochastic optimization in linear dynamical systems, peer-to-peer distributed optimization schemes, decision problems with dependent data, and stochastic optimization problems over combinatorial spaces. We present examples with various data-generating processes, including vector-auto regressive process and finite-state Markov Chain, to demonstrate that our approach outperforms other data-driven methods.

description: Accelerated MRI reconstructs images of clinical anatomies from sparsely sampled signal data to reduce patient scan times. While recent works have leveraged deep learning to accomplish this task, such approaches have often only been explored in simulated environments where there is no signal corruption or resource limitations. In this work, we explore augmentations to neural network MRI image reconstructors to enhance their clinical relevancy. Namely, we propose a ConvNet model for detecting sources of image artifacts that achieves a classifier $F_2$ score of 79.1%. We also demonstrate that training reconstructors on MR signal data with variable acceleration factors can improve their average performance during a clinical patient scan by up to 2%. We offer a loss function to overcome catastrophic forgetting when models learn to reconstruct MR images of multiple anatomies and orientations. Finally, we propose a method for using simulated phantom data to pre-train reconstructors in situations with limited clinically acquired datasets and compute capabilities. Our results provide a potential path forward for clinical adaptation of accelerated MRI.

Battery-less RFID-Based Wireless Sensor Architectures for 5G IoT Applications
Creators: Khalid, Nabil
Publisher: name: University of Alberta Library
Year: 2023

In this thesis, novel battery-less wireless sensor architectures and sensing elements are proposed and demonstrated. The proposed passive wireless sensor architectures integrate a UHF RFID chip, and a UHF sensing element to enable the reading of environmental conditions wirelessly, without increasing the complexity of a typical RFID chip and substantial loss of read range of the chip. The architectures are designed so that the sensor only changes the phase of the reflected RFID signal, with minimal affects to the incoming interrogator signal to ensure optimal range. The phase change is detected by the reader using a non-coherent IQ demodulator. Since the sensing elements must be responsive at UHF, novel sensing elements are designed and reported.

description: In this paper, we investigate the exact solution of an anisotropic space-time in the context of $f(Q)$ gravity, where $f\left( Q\right) $ is the arbitrary function of the non-metricity scalar $Q$.

Using power-law cosmology ($a\left( t\right) \propto t^{m}$), we analyze the physical behavior of cosmological parameters such as the energy density, pressure, EoS parameter, skewness parameter. Further, we validated the model with energy conditions and found that our $f\left( Q\right) $\ cosmological model behaves like the quintessence model in the present and $% Λ$CDM in the future.

description: It is well-known that many topological phase transitions of intrinsic Abelian topological phases are accompanied by condensation and confinement of anyons. However, for non-Abelian topological phases, more intricate phenomena can occur at their phase transitions, because the multiple degenerate degrees of freedom of a non-Abelian anyon can change in different ways after phase transitions. In this paper, we study these new phenomena, including partial condensation, partial deconfinement and especially anyon splitting (a non-Abelian anyon splits into different kinds of the new anyon species) using projected entangled pair states (PEPS). First, we show that anyon splitting can be observed from the topologically degenerate ground states. Next, we construct a set of PEPS describing all possible degrees of freedom of the same non-Abelian anyon. From the overlaps of this set of PEPS of a given non-Abelian anyon with the ground state, we can extract the information of partial condensation. Then, we construct a central object, a matrix defined by the norms and overlaps among the PEPS in that set. The information of partial deconfinement can be extracted from this matrix. In particular, we use it to construct an order parameter which can directly detect anyon splitting. We demonstrate the power of our approach by applying it to a range of non-Abelian topological phase transitions: From $D(S_3)$ quantum double to toric code, from $D(S_3)$ quantum double to $D(Z_3)$ quantum double, from Rep($S_3$) string-net to toric code, and finally from double Ising string-net to toric code.

Hippocampal Diffusion Tensor Imaging in Parkinson's Disease and Associations with Non- Motor Symptoms
Creators: Budd, Alexandra
Publisher: name: University of Alberta Library
Year: 2023

Parkinson’s disease (PD) is the second most common neurodegenerative disorder and causes not only well-characterised motor symptoms, but also a host of non-motor symptoms that greatly impact quality of life. PD exists within a larger spectrum of disorders caused by the accumulation of Lewy bodies within the brain. This spectrum also includes Dementia with Lewy Bodies (DLB), and different cognitive subtypes of PD, such as PD with mild cognitive impairment (PD-MCI) and PD with dementia (PDD). There is still much to be learnt about non-

motor symptoms and progression in the brains of patients with diseases within the Lewy body spectrum. One region of the brain that may be implicated in non-motor symptoms is the

hippocampus, which is a site that develops marked pathology as the disease spreads through the brain. However, few studies prior to this time have been able to investigate the microstructure of the hippocampus in PD and DLB patients in vivo, making it difficult to characterize ongoing non-motor symptoms and their relationship to non-motor symptoms in living patients.

Recently, a novel diffusion tensor imaging (DTI) technique has been developed to allow high resolution diffusion imaging of the hippocampus. In this project, high resolution imaging was used to first investigate hippocampal changes in 38 patients with Lewy body spectrum diseases relative to 40 healthy older adult controls. After an initial visual inspection of the hippocampi and counting of the hippocampal digitations, no overt differences between groups were apparent. Next, we determined the association between hippocampal measures and non-motor symptoms in participants with PD and DLB. We found that fractional anisotropy (FA), but not mean diffusivity (MD) or volume (as derived from DTI), was altered in the hippocampus of patients with PD and DLB, and that FA was decreased in patients with PD and DLB when compared to controls. Furthermore, diffusion measures were correlated with age, with FA and volume decreasing and MD increasing with age as expected, but not all results were statistically significant across groups. In participants with PD and DLB, we found that patients with worse depression or sleep disturbances had higher FA than those who were less affected.

Using the new improved method of DTI for imaging the hippocampus has allowed a more in-depth look into the hippocampal structure of living patients with PD and DLB. However, further studies are needed to understand the reasons for the direction of diffusion changes uncovered. Further studies that examine the relationship between non-motor symptoms in regions and diffusion changes beyond the hippocampus proper are also needed.

description: Purpose: Sugar is the most common food product necessary for human life, the main component of which is sucrose and other impurities. The exchange-based nature of the sugar trade makes it easier to enter the market and helps to remove market barriers. The world sugar market is one of the most important in the system of food markets. Approach/Methodology/Design: Within the study, general scientific methods of analysis and synthesis, such as generalization, comparison, abstract-logical analysis, index method, etc. were used. Findings: At the present stage, the world sugar market is characterised by significant qualitative changes, which occur due to the influence of factors determining the conjuncture, and the development of international globalisation processes. The correlation between supply and demand in different regions and countries and the structure are changing, and there is regional redistribution of cane and beet sugar exports and imports. Today, people are interested in production of classic white sugar, pressed or molded lump sugar, candy sugar, powdered sugar and water sugar syrup. Alternative uses of raw sugar have emerged that have a significant impact on market trends and price volatility (primarily bioethanol, biogas, and sugar substitute markets), price volatility has increased. Practical Implications: The results of the performed analysis are necessary for assessing the level of food security of sugar market and for the growth of export of that product, taking into account the trends and conditions for the functioning of the agro-food sector. The main trends in the development of the world sugar market are changes in the structure of its consumption, characterised by an increase in demand for sugar from the food industry and a decrease in consumption by the population, as well as the increased role of bioethanol production. Originality/Value: The results of the analysis are necessary to assess the level of food safety and to develop a strategy that takes into account the current trends in the global sugar market. Prospective directions for the sustainable development of the sugar market have been developed.

Boron-Mediated Lignocellulose Degradation. Design, Synthesis, Properties, and Applications of Boron-Containing Naphthoids

Lewis acidity is a molecule’s tendency to accept a pair of electrons. Trivalent boron compounds are archetypical Lewis acids due to the presence of a vacant p orbital, leading to many uses in organic synthesis. For example, boron trihalides use their intrinsic Lewis acidity to accept ether oxygen electrons, facilitating ether cleavage reactions. On the other hand, organoboron compounds are commonly used in catalysis, such as in the Corey-Bakshi-Shibata reduction method. An interesting class of organoboron compounds that have recently gained prominence in the field of medicinal chemistry is boron-containing heterocycles. They are used in a number of fascinating applications and, in particular, have appeared in several FDA approved drugs. Despite the significance of boron-containing compounds, many aspects of their physicochemical properties, reactivity, and potential applications remain underexplored.

Lignocellulose is a plant biomass formed by ether and acetal linkages of phenolic and sugar monomers. Chapter 2 of this thesis describes the use of a mild method that utilizes mixed boron trihalides for processing lignocellulose into cellulose and lignin components. Such materials may offer a route to sustainable chemical production, alleviating the need for non-renewable petroleum-based feedstocks. The applicability of this method was demonstrated with a sample of white pine sawdust, followed by spectroscopic analyses and dye-staining methods.

Boron-containing heterocycles are an important motif in material science and drug discovery. As such, a comprehensive understanding of their properties is needed to enable new applications. The acidic nature of certain hemiboronic acids, such as boron-containing naphthoids, has been a point of argument for a long time, and there has been no definite evidence regarding their aromatic character. Chapter 3 addresses these questions, along with other characteristics of boron-containing naphthoids, such as their stability and their boranol (B—OH) exchange with alcohols. Overall, this study clarifies a large body of conflicting results reported in the literature over several decades and provides important conclusions for the systematic applications of boron-containing naphthoids in the areas of catalysis and medicinal chemistry.

Chapter 4 further examines the physical properties of boron-containing naphthoids and their suitability as drug scaffolds. Moreover, new and chemoselective synthetic strategies and purification procedures are described. Small prototypical compound libraries for different boron-containing naphthoid scaffolds were produced. Many such compounds are drug bioisosteres and were subsequently evaluated in biological activity assays.

description: The metallicity of exoplanet systems serves as a critical diagnostic of planet formation mechanisms. Previous studies have demonstrated the planet-metallicity correlation for large planets ($R_P\ \geq\ 4\ R_E$); however, a correlation has not been found for smaller planets. With a sample of 406 $Kepler$ Objects of Interest whose stellar properties are determined spectroscopically, we reveal a universal planet-metallicity correlation: not only gas-giant planets ($3.9\ R_E\ < R_P\ \leq\ 22.0\ R_E$) but also gas-dwarf ($1.7\ R_E\ < R_P\ \leq\ 3.9\ R_E$) and terrestrial planets ($R_P\ \leq\ 1.7\ R_E$) occur more frequently in metal-rich stars. The planet occurrence rates of gas-giant planets, gas-dwarf planets, and terrestrial planets are $9.30^{+5.62}_{-3.04}$, $2.03^{+0.29}_{-0.26}$, and $1.72^{+0.19}_{-0.17}$ times higher for metal-rich stars than for metal-poor stars, respectively.

description: Quantum Machine Learning (QML) hasn't yet demonstrated extensively and clearly its advantages compared to the classical machine learning approach. So far, there are only specific cases where some quantum-inspired techniques have achieved small incremental advantages, and a few experimental cases in hybrid quantum computing are promising considering a mid-term future (not taking into account the achievements purely associated with optimization using quantum-classical algorithms). The current quantum computers are noisy and have few qubits to test, making it difficult to demonstrate the current and potential quantum advantage of QML methods. This study shows that we can achieve better classical encoding and performance of quantum classifiers by using Linear Discriminant Analysis (LDA) during the data preprocessing step. As a result, Variational Quantum Algorithm (VQA) shows a gain of performance in balanced accuracy with the LDA technique and outperforms baseline classical classifiers.

description: In this paper we study a particular aspect of the urban community policing: routine patrol route planning. We seek routes that guarantee visibility, as this has a sizable impact on the community perceived safety, allowing quick emergency responses and providing surveillance of selected sites (e.g., hospitals, schools). The planning is restricted to the availability of vehicles and strives to achieve balanced routes. We study an adaptation of the model for the multi-vehicle covering tour problem, in which a set of locations must be visited, whereas another subset must be close enough to the planned routes. It constitutes an NP-complete integer programming problem. Suboptimal solutions are obtained with several heuristics, some adapted from the literature and others developed by us. We solve some adapted instances from TSPLIB and an instance with real data, the former being compared with results from literature, and latter being compared with empirical data.

description: We report magnetoresistance measurements on thin Pt bars grown on epitaxial (001) and (111) CoFe2O4 (CFO) ferrimagnetic insulating films. The results can be described in terms of the recently discovered spin Hall magnetoresistance (SMR). The magnitude of the SMR depends on the interface preparation conditions, being optimal when Pt/CFO samples are prepared in situ, in a single process. The spin-mixing interface conductance, the key parameter governing SMR and other relevant spin-dependent phenomena such as spin pumping or spin Seebeck effect, is found to be different depending on the crystallographic orientation of CFO, highlighting the role of the composition and density of magnetic ions at the interface on spin mixing.
