description: We review the results of a phenomenological model for cold and dense nuclear matter exhibiting a chiral phase transition. The idea is to model the quark-hadron phase transition under neutron star conditions within a single model, but without adding quark degrees of freedom by hand. To this end, strangeness is included in the form of hyperonic degrees of freedom, whose light counterparts provide the strangeness in the chirally restored phase. In the future, the model can be used for instance to compute the surface tension at the (first-order) chiral phase transition and to study the possible existence of inhomogeneous phases.

description: Thermal bombs are a widely used method to artificially trigger explosions of core-collapse supernovae (CCSNe) to determine their nucleosynthesis or ejecta and remnant properties. Recently, their use in spherically symmetric (1D) hydrodynamic simulations led to the result that {56,57}Ni and 44Ti are massively underproduced compared to observational estimates for Supernova 1987A, if the explosions are slow, i.e., if the explosion mechanism of CCSNe releases the explosion energy on long timescales. It was concluded that rapid explosions are required to match observed abundances, i.e., the explosion mechanism must provide the CCSN energy nearly instantaneously on timescales of some ten to order 100 ms. This result, if valid, would disfavor the neutrino-heating mechanism, which releases the CCSN energy on timescales of seconds. Here, we demonstrate by 1D hydrodynamic simulations and nucleosynthetic post-processing that these conclusions are a consequence of disregarding the initial collapse of the stellar core in the thermal-bomb modelling before the bomb releases the explosion energy. We demonstrate that the anti-correlation of 56Ni yield and energy-injection timescale vanishes when the initial collapse is included and that it can even be reversed, i.e., more 56Ni is made by slower explosions, when the collapse proceeds to small radii similar to those where neutrino heating takes place in CCSNe. We also show that the 56Ni production in thermal-bomb explosions is sensitive to the chosen mass cut and that a fixed mass layer or fixed volume for the energy deposition cause only secondary differences. Moreover, we propose a most appropriate setup for thermal bombs.

description: We present a numerical method to produce stochastic dynamics according to the generalized Langevin equation with a non-stationary memory kernel. This type of dynamics occurs when a microscopic system with an explicitly time-dependent Liouvillian is coarse-grained by means of a projection operator formalism. We show how to replace the deterministic fluctuating force in the generalized Langevin equation by a stochastic process, such that the distributions of the observables are reproduced up to moments of a given order. Thus, in combination with a method to extract the memory kernel from simulation data of the underlying microscopic model, the method introduced here allows to construct and simulate a coarse-grained model for a driven process.

description: Context. Our knowledge of populations and occurrence of planets orbiting evolved intermediate-mass stars is still incomplete. In 2010 we started a planet-search program among 95 giant stars observed by the Kepler mission to increase the sample of giant stars with planets and with reliable estimates of stellar masses and radii. Aims. We present the two systems KIC 3526061 and HD 187878 from our planet-search program for which we could characterise their companions. Methods. We used precise stellar radial velocity measurements taken with four different echelle spectrographs to derive an orbital solution. We used Gaia astrometric measurements to obtain the inclination of the HD 187878 system and Kepler photometric observations to estimate the stellar mass and radius. Results. We report the discovery of a sub-stellar and a stellar companion around two intermediate-mass red giant branch stars. KIC 3526061 b is most likely a brown dwarf with a minimum mass of 18.15 Jupiter masses in a long-period eccentric orbit, with the orbital period 3552 d and orbital eccentricity 0.85. It is the most evolved system found having a sub-stellar companion with such a large eccentricity and wide separation. HD 187878 B has a minimum mass of 78.4 Jupiter masses. Combining the spectroscopic orbital parameters with the astrometric proper motion anomaly we derived an orbital inclination 9.8 deg, which corresponds to the companion's mass in the stellar regime of 0.51 Sun mass. Conclusions. A sub-stellar companion of KIC 3526061 extends the sample of known red giant branch stars with sub-stellar companions on very eccentric wide orbits and might provide a probe of the dynamical evolution of such systems over time.

Textile Fibre Fragments in Marine Environments and their Interaction with Suspended Hydrocarbons
Creators: Arredondo Campos, Oscar Rene
Publisher: name: University of Alberta Library
Year: 2023

Pollution by microplastics is one of the biggest current environmental problems, due to the great amount of plastic waste that is used worldwide, as well as the threat they represent to fauna that might ingest them, particularly in aquatic environments. One of the main sources of microplastics, is the shedding of synthetic fibre garments during laundering. The impact of these particles relies not only on the internal physical damage, but also on their capacity to absorb harmful pollutants in the water systems, acting as a concentrating vector. The effectiveness of these textiles fragments to absorb different pollutants is dependant on their physical morphology as well as their fibre chemistry. The purpose of this study was to evaluate the sorption capacity of four polyaromatic hydrocarbon (PAHs) pollutants by textiles fragments coming from three types of fabrics used in the textile industry. The experimental fabrics were 100% fibre content plain weave cotton, polyamide, and polyester. The selected PAHs are commonly found in by-products of fossil fuels combustion and tobacco smoke, phenanthrene, pyrene, fluoranthene and carbazole. Small fragments of each type of fabric were submerged in saturated solutions of each compound in deionized and artificial saltwater for 24 hours with gentle agitation twice per day. Aliquots of the aqueous phase was filtered and recovered via liquid-liquid extraction with dichloromethane, to be analyzed through gas chromatography – flame ionization detection.

The results showed a trend in the absorption capacity for the three fabrics. Cotton presented the lowest affinity towards the PAHs, followed by polyamide, while polyester showed the highest affinity towards them. Hydrophobic and hydrophilic sites in the fibres structure might be the main driving force that control these interaction pollutants-fibres. This work has showed that while both types of natural and synthetic textiles have the potential to absorb PAHs compounds from aquatic systems, synthetic fibres interact easier and at a higher degree with them.

description: We study the evolution of the renormalized volume functional for asymptotically Poincare-Einstein metrics (M,g) which are evolving by normalized Ricci flow. In particular, we prove that the time derivative of the renormalized volume along the flow is the negative integral of scal(g(t)) + n(n-1) over the manifold. This implies that if scal(g(0))+n(n-1) is non-negative at t=0, then the renormalized volume decreases monotonically. We also discuss how, when n=4, our results describe the Hawking-Page phase transition. Differences in renormalized volumes give rigorous meaning to the Hawking-Page difference of actions and describe the free energy liberated in the transition.

Mit dem Beschluss des Barrierefreiheitsstärkungsgesetzes soll ihnen ein gleichberechtigter Zugang zu bestimmten digitalen Diensten ermöglicht werden. Diese Arbeit befasst sich speziell mit den Anforderungen an die Barrierefreiheit in mobilen Anwendungen. Auf Grundlage der Web Content Accessibility Guidelines wird in dieser theoretischen Arbeit erläutert, wie eine App konzipiert und gestaltet werden muss, um barrierefrei zu sein. Das Ziel ist darzulegen, wie die verschiedenen Barrieren, die die Zugänglichkeit und Nutzbarkeit von mobilen Anwendungen für Menschen mit unterschiedlichen Arten von Behinderungen einschränken, vermieden oder beseitigt werden können. Dafür wird anhand konkreter Beispiele aufgezeigt, welche Barrieren im Zusammenhang mit verschiedenen Behinderungen die größten Schwierigkeiten bei der Bedienung auslösen. Aus der Betrachtung der international anerkannten Zugänglichkeitsrichtlinien geht hervor, dass zur Behebung dieser Probleme die Wahrnehmbarkeit, Bedienbarkeit, Verständlichkeit und Robustheit gewährleistet sein müssen, welche auch in Apps die Grundlage für Barrierefreiheit darstellen. Auf Basis dieser vier Prinzipien werden die Besonderheiten von Barrierefreiheit in mobilen Anwendungen und ihre typischen Probleme beschrieben, woraufhin Maßnahmen und Lösungen für mehr Accessibility in Apps herausgearbeitet werden. Zudem wird erläutert, ob und wie Kontrollen durchgeführt werden können, damit in Zukunft die Barrierefreiheit garantiert werden kann.

description: A catalog of 824 fireballs (bright meteors), observed by a dedicated network of all-sky digital photographic cameras in central Europe in the years 2017-2018 is presented. The status of the European Fireball Network, established in 1963, is described. The cameras collect digital images of meteors brighter than an absolute magnitude of about -2 and radiometric light curves with a high temporal resolution of those brighter than a magnitude ~ -4. All meteoroids larger than 5 grams, corresponding to sizes of about 2 cm, are detected regardless of their entry velocity. High-velocity meteoroids are detected down to masses of about 0.1 gram. The largest observed meteoroid in the reported period 2017-2018 had a mass of about 100 kg and a size of about 40 cm. The methods of data analysis are explained and all catalog entries are described in detail. The provided data include the fireball date and time, atmospheric trajectory and velocity, the radiant in various coordinate systems, heliocentric orbital elements, maximum brightness, radiated energy, initial and terminal masses, maximum encountered dynamic pressure, physical classification, and possible shower membership. Basic information on the fireball spectrum is available for some bright fireballs (apparent magnitude < -7). A simple statistical evaluation of the whole sample is provided. The scientific analysis is presented in an accompanying paper.

description: Magnetic particle imaging (MPI) is an emerging medical imaging technique that has high sensitivity, contrast and excellent depth penetration. In x-space MPI reconstruction, the reconstructed native image can be modeled as a convolution of the magnetic particle concentration with a point-spread function (PSF). The deconvolution is practical and valuable as a post-processing way to deblur the native image. However, to accurately measure or model the PSF used for deconvolution is challenging due to the imperfection of hardware and magnetic particle relaxation. The inaccurate PSF may lead to the loss of the content structure of the MPI image. In this study, we developed a dual adversarial framework with contrastive constraint (DC_GAN) to deblur the MPI image. We evaluate the performance of the proposed DC_GAN model on simulated and real data. Experimental results confirm that our model performs favorably against the deconvolution method that are mainly used for deblurring the MPI image.

description: Meteoroids impacting the Earth on a daily basis are fragments of asteroids and comets. By studying fireballs produced during their disintegration in the atmosphere, we can gain information about their source regions and the properties of their parent bodies. In this work, data on 824 fireballs presented in an accompanying paper and catalog are used. We propose a new empirical parameter for the classification of the physical properties of meteoroids, based on the maximum dynamic pressure suffered by the meteoroid in the atmosphere. We then compare the physical and orbital properties of meteoroids. We find that aphelion distance is a better indicator of asteroidal origin than the Tisserand parameter. Meteoroids with aphelia lower than 4.9 AU are mostly asteroidal, with the exception of the Taurids and alpha Capricornids associated with the comets 2P/Encke and 169P/NEAT, respectively. We found another population of strong meteoroids of probably asteroidal origin on orbits with either high eccentricities or high inclinations, and aphelia up to ~ 7 AU. Among the meteoroid streams, the Geminids and eta Virginids are the strongest, and Leonids and alpha Capricornids the weakest. We found fine orbital structures within the Geminid and Perseid streams. Four minor meteoroid streams from the working list of the International Astronomical Union were confirmed. No meteoroid with perihelion distance lower than 0.07 AU was detected. Spectra are available for some of the fireballs, and they enabled us to identify several iron meteoroids and meteoroids deficient in sodium. Recognition and frequency of fireballs leading to meteorite falls is also discussed.

description: We use the measured X-ray luminosity function (XLF) of high-mass X-ray binaries (HMXBs) in nearby star-forming galaxies to constrain the common envelope (CE) mechanisms, which play a key role in governing the binary evolution. We find that the XLF can be reproduced quite closely under both CE mechanisms usually adopted, i.e., the $α_{\rm CE}$ formalism and the $γ$ algorithm, with a reasonable range of parameters considered. Provided that the parameter combination is the same, the $γ$ algorithm is likely to produce more HMXBs than the $α_{\rm CE}$ formalism, by a factor of up to $\sim$ 10. In the framework of the $α_{\rm CE}$ formalism, a high value of $α_{\rm CE}$ is required to fit the observed XLF, though it does not significantly affect the global number of the HMXB populations. We present the detailed components of the HMXB populations under the $γ$ algorithm and compare them with those in Zuo et al. and observations. We suggest the distinct observational properties, as well as period distributions of HMXBs, may provide further clues to discriminate between these two types of CE mechanisms.

Tile Embeddings: A General Representation for Procedural Level Generation via Machine Learning
Creators: Jadhav, Mrunal Sunil
Publisher: name: University of Alberta Library
Year: 2023

Procedural Level Generation via Machine Learning (PLGML) refers to the application of machine learning techniques to the automated generation of game levels. PLGML researchers have investigated different level generation techniques to generate new game levels matching the style of a training corpus. While the PLGML community has made notable progress in designing impressive level generators, we are still far from achieving the holy grail of generalizability. Generalizability refers to a level generators’ ability to generate a previously unseen, new game level based on the training data used to build the model. A primary reason for this is the limited availability of PLGML datasets and inconsistent level representation practices across different games. Traditionally employed PLGML datasets are hand-annotated by domain experts and fan communities. The process of curating clean datasets is time-consuming. Hence, even though many video games exist, select few have received a disproportionate amount of research attention.

Towards this goal of generalizability, we propose a representation learning approach for game level design. We introduce tile embeddings, a continuous, unified affordance-rich representation of 2D games. This thesis covers an initial implementation of tile embeddings and their further modification to handle the particular case of skewed tile distribution observed in games like Super Mario Bros.. We then introduce a novel, two-step level generation process that can leverage the flexibility of a discrete representation with the expressivity of continuous tile embeddings. We evaluate our tile embedding representation on its ability to predict affordances for unannotated tiles and to serve as a PLGML representation for annotated games.

We perform an ablation study for level generation of Super Mario Bros., and further show the ability to apply our approach to level generation for unannotated games. Our outputs cover generative spaces matching the distribution of the original training data, thus demonstrating the potential of tile embeddings for PLGML applications for any tile-based 2D games. The presented thesis attempts to address the core challenges of PLGML around representation and dataset availability. We believe with more work in this direction, our approach has the power to open new horizons for PLGML research.

description: In the extended quasidilaton massive gravity we perform a nonlinear transformation of the shift vector and then calculate the second derivatives of the Hamiltonian density with respect to the lapse function and the (nonlinearly transformed) shift vector. It is then shown that the $4\times 4$ Hessian matrix is invertible, meaning that the equations of motion for the lapse function and the shift vector simply determine themselves. Therefore, there is no primary constraint that removes the Boulware-Deser ghost.

description: We investigate the one-dimensional long-range random-field Ising magnet with Gaussian distribution of the random fields. In this model, a ferromagnetic bond between two spins is placed with a probability $p \sim r^{-1-σ}$, where $r$ is the distance between these spins and $σ$ is a parameter to control the effective dimension of the model. Exact ground states at zero temperature are calculated for system sizes up to $L = 2^{19}$ via graph theoretical algorithms for four different values of $σ\in \{0.25,0.4,0.5,1.0\}$ while varying the strength $h$ of the random fields. For each of these values several independent physical observables are calculated, i.e., magnetization, Binder parameter, susceptibility and a specific-heat-like quantity. The ferromagnet-paramagnet transitions at critical values $h_c(σ)$ as well as the corresponding critical exponents are obtained. The results agree well with theory and interestingly we find for $σ= 1/2$ the data is compatible with a critical random-field strength $h_c > 0$.

description: We use holography to study the spectra of boundary conformal field theories (BCFTs). To do so, we consider a 2-dimensional Euclidean BCFT with two circular boundaries that correspond to dynamical end-of-the-world branes in 3-dimensional gravity. Interactions between these branes inform the operator content and the energy spectrum of the dual BCFT. As a proof of concept, we first consider two highly separated branes whose only interaction is taken to be mediated by a scalar field. The holographic computation of the scalar-mediated exchange reproduces a light scalar primary and its global descendants in the closed-string channel of the dual BCFT. We then consider a gravity model with point particles. Here, the interaction of two separated branes corresponds to a heavy operator which lies below the black hole threshold. However, we may also consider branes at finite separation that "merge" non-smoothly. Such brane mergers can be used to describe unitary sub-threshold boundary-condition-changing operators in the open-string spectrum of the BCFT. We also find a new class of sub-threshold Euclidean bra-ket wormhole saddles with a factorization puzzle for closed-string amplitudes.

description: The Temperley-Lieb algebra \tln(β) can be defined as the set of rectangular diagrams with n points on each of their vertical sides, with all points joined pairwise by non-intersecting strings. The multiplication is then the concatenation of diagrams. The dilute Temperley-Lieb algebra \dtl n(β) has a similar diagrammatic definition where, now, points on the sides may remain free of strings. Like \tl n, the dilute \dtl n depends on a parameter β\in\mathbb C, often given as β=q+q^{-1} for some q\in\mathbb C^\times. In statistical physics, the algebra plays a central role in the study of dilute loop models. The paper is devoted to the construction of its principal indecomposable modules. Basic definitions and properties are first given: the dimension of \dtl n, its break up into even and odd subalgebras and its filtration through n+1 ideals. The standard modules \U{n,k} are then introduced and their behaviour under restriction and induction is described. A bilinear form, the Gram product, is used to identify their (unique) maximal submodule \dr{n,k} which is then shown to be irreducible or trivial. It is then noted that \dtl n is a cellular algebra. This fact allows for the identification of complete sets of non-isomorphic irreducible modules and projective indecomposable ones. The structure of \dtl n as a left module over itself is then given for all values of the parameter q, that is, for both q generic and a root of unity.

Granular activated carbon sparking anaerobic digestion: the path to municipal sewage resource recovery
Creators: Zhang, Yingdi
Publisher: name: University of Alberta Library
Year: 2023

Anaerobic digestion (AD) is an effective and economical technology that can convert organic pollutants to biomethane, playing a pivotal role in resource recovery and greenhouse gas emission control. However, the anaerobic treatment of municipal sewage under psychrophilic conditions faces significant challenges. The overall goal of this research is to investigate, develop, and optimize carbon-based materials (CBMs) amended AD of municipal sewage under psychrophilic conditions for biomethane recovery. This research deepens understanding of fundamental anaerobic processes, improves AD technology effectiveness, and contributes to implementing a circular economy.

CBMs, such as granular activated carbon (GAC), have been shown to promote direct interspecies electron transfer (DIET) in anaerobic co-culture experiments; however, their roles in continuous feeding AD with mixed cultures remain unknown. This Ph.D. research thoroughly explored the roles of GAC in laboratory-scale up-flow anaerobic sludge blankets (UASBs) treating municipal sewage, focusing on alteration of electron transfer, biosynthesis of growth factors (e.g., amino acids and vitamins), impacts of sulfate concentrations, as well as microbiome developments and physiological changes. Over the past four and a half years, 14 bioreactors were operated. Experiments were performed at both University of Alberta laboratories and in the field of a full-scale municipal wastewater treatment plant. Under all operation conditions, it was observed that GAC addition could significantly enhance AD reactor performance, methanogenic activities and effectiveness in vital syntrophic partnerships.

This thesis led to several innovations. In particular, this study is the first to operate continuous GAC-amended UASB for municipal sewage treatment under psychrophilic conditions, focusing on the development of an electro-active microbiome. More importantly, this study fully demonstrates (i) the shift of electron transfer pathway with GAC addition in continuous feeding AD by a range of methods, (ii) the roles of GAC in stimulating the biosynthesis of growth factors and their positive impacts on microbiome development and reactor performance, (iii) the impacts of GAC addition on microbiome resistance to H2S toxicity and sulfate reduction activities.

The results of this thesis provide insights into the changes in microbial communities, physiologies, and metabolites with GAC addition, and demonstrate that GAC addition is a feasible approach to enhance the AD performance of municipal sewage under psychrophilic conditions. This research deepens our understanding of the roles of CBMs in AD and provides significant guidance both in theory and practice.

A Toolbox of Humanized Recombinant Antibody Fragments for Prion Diseases
Creators: Rathod, Vineet S.
Publisher: name: University of Alberta Library
Year: 2023

Prion diseases are rare, inexorably progressive, and fatal neurodegenerative disorders, with no therapy other than palliation. The key event in the pathogenesis of prion diseases is the conformational conversion of the cell-surface glycoprotein (PrPC), from a predominantly α-helical structure into an infectious, aggregated isoform (PrPSc), with β-sheet oligomers and amyloid fibrils. Multiple abnormal PrP structures have been observed both in vivo and in vitro, and determining which are relevant to disease, that is, infectious and/or toxic, is a major challenge. Recently high-resolution structures of brain-derived prion strains revealed a parallel in-register intermolecular β-sheet (PIRIBS) structure, which is in conflict with brain-derived X-ray fiber diffraction patterns proposing a four-rung β-solenoid (4RβS) architecture. Antibodies are powerful tools for protein purification and molecular detection. Although conventional antibodies are ideal for most applications, the performance of certain assays is enhanced by using antibody fragments. Fab fragments (Fabs) are small antibody derivatives that maintain antigen-binding capacity. One of the advantages of Fabs over intact antibodies is they are small in size, which allows them to penetrate deeper into protein aggregates, such as amyloid fibrils. However, having antibodies that are conformational dependent on proteins such as the pathologic conformation of PrPSc recognizing the toxic oligomers and fibrils has enormous value for biomedical research and therapeutics of prion diseases. I established a pipeline to produce recombinant humanized antibody fragments for prions derived from phage display technology and hybridoma clones. The fully functional and soluble antibody fragments were characterized extensively using linear PrP peptides and via structural epitope mapping of PrPSc-specific antibody fragments. This allowed me to build a toolbox of various recombinant antibody fragments, including engineered conformational PrPSc-specific antibody fragments and small conjugated antibody derivatives. I used these to perform ultrastructural analyses of animal and human prions using immunogold labelling, direct detection of prions, and in-vitro structural analysis of genetic prions using time-dependent folding immunoassay.Taken together, these recombinant humanized antibody fragments provide an alternate approach to understand the structural relationships and pathophysiological roles of various prion ultrastructures and offer potential therapeutic candidates for prion diseases.

description: Magnetic particle imaging (MPI) is an emerging and highly sensitive imaging method. Multi-color MPI allows simultaneous identification of different materials. Obtaining precise relaxation time is one of the key challenges in achieving multi-colored MPI. In this paper, we propose a physical information based deep learning framework to accurately decompose the mixed signal into the original independent relaxation signals. By transforming the Debye relaxation model into a differential loss function, our network is able to efficiently utilize physical prior information. In simulation experiments with different signal-to-noise ratios and different signal counts, our method shows better performance than the PDCO algorithm. The imaging effect of our algorithm and PDCO algorithm in the presence of multiple materials was evaluated by three-color imaging simulation experiment. In addition, spectral imaging of a digital vascular phantom was simulated by combining a field-free point with homogeneous pulsed excitation. In vascular phantom simulation experiment, our method images blood vessels, metal guidewires, and stents in a single imaging process, showing excellent application potential in cardiac stent surgery.

Let's Talk About Sex - Or Not: Sexual Communication, Self-Efficacy, and Sexual Healthcare Use Among Individuals With and Without Communication Difficulties
Creators: Hughes, Shelby
Publisher: name: University of Alberta Library
Year: 2023

Sexual communication is an essential element of sexual satisfaction and wellbeing. However, individuals with communication difficulties (in reading, writing, speaking, or understanding language) may face barriers to sexual communication in interpersonal and healthcare contexts. Based on previous research, communication difficulties are associated with reduced intimacy (Lemieux et al., 2001; Korpelainen et al., 1999), difficulty accessing healthcare (Stransky et al., 2018), and increased vulnerability to sexual assault (Brownlie et al., 2007; 2017). Individuals with communication difficulties also report lower general and social self-efficacy compared to individuals without communication difficulties (Botting et al., 2016; Durkin et al., 2017). Given these low levels of self-efficacy, it was hypothesized that individuals with communication difficulties may have less confidence in their ability to navigate discussions of sex and sexual health.

 Using Social Cognitive Theory (SCT) (Bandura; 1986) as a framework, this study explored the relationship between self-efficacy and subsequent sexual behaviours (use of sexual healthcare services, avoidance of sexual healthcare services, use of protection during sexual encounters, and frequency of sexual health discussions with a partner). Participants with and without communication difficulties completed an anonymous online survey (N = 262; N = 43 with self-reported communication difficulties; Mage = 28.39, SDage = 10.97; 185 females). Mann Whitney U-tests compared individuals with and without communication difficulties on three measures of self-efficacy (general, sexual communication, and healthcare communication), as well as level of self-reported comfort and confidence in accessing sexual health services. Significant differences were found between groups, with individuals who reported communication difficulties scoring lower on all five variables. Regression analyses were used to explore the utility of the three self-efficacy constructs in predicting behavioural outcomes. Healthcare communication self-efficacy predicted access to sexual healthcare, and less avoidance. Sexual communication self-efficacy predicted less avoidance of sexual healthcare. These findings suggest that individuals with communication difficulties experience greater barriers to sexual communication and sexual healthcare than the general population, and that specific self-efficacy constructs predict sexual healthcare utilization. Potential implications for clinical practice are discussed, including the importance of initiating conversations about sexuality and building task-specific forms of self-efficacy in communication intervention.
Studying Limitations of Generative Transformer based models for Aspect Based Sentiment Analysis

Companies can only progress if they understand what their customers feel about their products and services. With companies having an online presence, and with the availability of third-party online reviewing platforms like Yelp, it becomes critical to scour through online reviews. Analysing millions of online reviews across various platforms is not a trivial task. Aspect-based Sentiment Analysis (ABSA) is an NLP task useful for automating such an analysis. ABSA solutions have historically used discriminative models, but there have been recent advances in the field which use generative transformer models (like T5 and BART). Generative ABSA models treat the ABSA task as a text generation problem. We study the latest generative ABSA models and discuss some of their limitations. We find that state-of-the-art generative ABSA models perform well for the standard ABSA settings. However, they face problems in certain real-life scenarios like handling cross-lingual settings and with reviews containing coreference resolution. We propose solutions for these limitations, justifying why they work.

Least quantile regression via modern optimization

description: We address the Least Quantile of Squares (LQS) (and in particular the Least Median of Squares) regression problem using modern optimization methods. We propose a Mixed Integer Optimization (MIO) formulation of the LQS problem which allows us to find a provably global optimal solution for the LQS problem. Our MIO framework has the appealing characteristic that if we terminate the algorithm early, we obtain a solution with a guarantee on its sub-optimality. We also propose continuous optimization methods based on first-order subdifferential methods, sequential linear optimization and hybrid combinations of them to obtain near optimal solutions to the LQS problem. The MIO algorithm is found to benefit significantly from high quality solutions delivered by our continuous optimization based methods. We further show that the MIO approach leads to (a) an optimal solution for any dataset, where the data-points $(y_i,\mathbf{x}_i)$'s are not necessarily in general position, (b) a simple proof of the breakdown point of the LQS objective value that holds for any dataset and (c) an extension to situations where there are polyhedral constraints on the regression coefficient vector. We report computational results with both synthetic and real-world datasets showing that the MIO algorithm with warm starts from the continuous optimization methods solve small ($n=100$) and medium ($n=500$) size problems to provable optimality in under two hours, and outperform all publicly available methods for large-scale ($n={}$10,000) LQS problems.

description: This paper investigates the effect of duty ratio on the background signal of handheld magnetic particle imaging (MPI) system. The background signal is the most influential noise signal in MPI system. Hand-held MPI systems need to be used continuously for long periods of time, so they are susceptible to interference from background signals. By adjusting the duty ratio and single detection time used by the system, a set of parameters with minimal background signal variation is determined. During the experiment, we summarized testing procedures to determine the most appropriate duty ratio for the MPI system, which can be tried on other MPI systems.
