An investigation of certain accounting-related stock market anomalies
Creators: name: Kim, Soh Yung
Publisher: name: University of British Columbia
Year: 2012

description: In financial markets, anomalies refer to empirical regularities in which security returns deviate from what would be expected in an informationally efficient market. This dissertation investigates explanations for stock market anomalies related to accounting information as documented by Dichev (1998) and Piotroski (2000). Using Ohlson’s (1980) measure of bankruptcy risk (O-Score), Dichev (1998) documents a bankruptcy risk anomaly in which firms with high bankruptcy risk earn lower than average returns. My study first demonstrates that the negative association between bankruptcy risk and returns does not generalize to alternative measures of bankruptcy risk. Then, by examining the nine individual components of O-Score, I find that funds from operations (FFO) is the only component that is associated with returns. Furthermore, I show that the return-predictive power of FFO is due to cash flows from operations. Taken as a whole, this study provides evidence that Dichev’s bankruptcy risk anomaly is a manifestation of investors’ under (over)-pricing of cash flows (accrual) component of earnings, i.e., the accrual anomaly documented by Sloan (1996). The second study investigates the effects of two potentially problematic research design choices which are often made in accounting-based studies of anomalies. I explore these issues by re-examining the results in Piotroski (2000), who finds that a simple, financial statement-based heuristic, when applied to a subset of firms with high book-to-market ratios, can discriminate between the firms that will eventually provide high returns and those that will be poor performers. I find that the relationship between Piotroski’s fundamental signals and subsequent returns is partly driven by the choice of return accumulation periods and the use of equally weighted re-turns. When the research design controls for both problems, the relationship disappears. Because the methods used in Piotroski are typical of those often employed in the accounting literature, this study suggests that evidence of profitable trading strategies and market inefficiency in the literature is likely to be overstated.

description: We study the interplay between chip-firing games and potential theory on graphs, characterizing reduced divisors ($G$-parking functions) on graphs as the solution to an energy (or potential) minimization problem and providing an algorithm to efficiently compute reduced divisors. Applications include an "efficient bijective" proof of Kirchhoff's matrix-tree theorem and a new algorithm for finding random spanning trees. The running times of our algorithms are analyzed using potential theory, and we show that the bounds thus obtained generalize and improve upon several previous results in the literature. We also extend some of these considerations to metric graphs.

description: Weak vector boson fusion provides a unique channel to directly probe the mechanism of electroweak symmetry breaking at hadron colliders. We present a method that allows to calculate total cross sections to next-to-next-to-leading order (NNLO) in QCD for an arbitrary V* V* -> X process, the so-called structure function approach. By discussing the case of Higgs production in detail, we estimate several classes of previously neglected contributions and we argue that such method is accurate at a precision level well above the typical residual scale and PDF uncertainties at NNLO. Predictions for cross sections at the Tevatron and the LHC are presented for a variety of cases: the Standard Model Higgs (including anomalous couplings), neutral and charged scalars in extended Higgs sectors and (fermiophobic) vector resonance production. Further results can be easily obtained through the public use of the VBF@NNLO code.

description: Edited magnetic resonance spectroscopy (MRS) can provide localized information on gamma-aminobutyric acid (GABA) concentration in vivo. However, GABA-edited MRS data has a low spectral quality, and many measurements, known as transients, need to be collected and averaged to obtain a high-quality spectrum, resulting in long scan times. This work investigated using deep learning (DL) with only a quarter of the number of conventionally acquired transients to shorten scan times by four while maintaining or improving spectral quality. A proof of concept was demonstrated by reconstructing GABA-edited spectra with only 80 transients and different configurations of DL-based pipelines. The best-performing pipeline used a proposed dimension-reducing 2D U-NET variation and it obtained better spectral quality metrics than conventionally reconstructed spectra with 320 transients. Simulated data was also shown to be useful in pre-training DL model weights. An open data challenge for reconstructing GABA-edited spectra from reduced transients was organized, and various DL models from different participating teams were compared. The challenge results reinforced the proof of concept conclusions that higher spectral quality can be achieved with DL reconstructions. However, the challenge metric evaluation also showed that DL models are able to undesirably exploit the limitations of conventional MRS metrics when using those as the training loss for the models, leading to good metric values but poor reconstructed spectra quality. DL reconstructions of GABA-edited MRS with 80 transients were also quantified and had significant differences from results from conventional reconstructions with 320 transients. However, given the lack of ground truths in the quantified data, it is not possible to conclude which results are closer to the actual concentrations. This work showed that DL methods can reduce GABA-edited MRS scan times while increasing spectral quality. Due to the lack of ground truths for the in vivo data, further studies are necessary to validate the concentrations obtained from the DL-based GABA-edited MRS reconstructions in comparison to conventional methods. This work was developed in the spirit of open science, and the data and code to reproduce the results were made publicly available.

description: Objective: To examine healthcare resource use and patient outcomes among critically ill patients who live in urban versus rural settings. Design: Retrospective cohort study. Setting: Medical, medical-surgical, and cardiovascular intensive care units (ICUs) in Alberta, Canada between January 1, 2014, and April 30, 2018. Patients: Those who survived their index ICU stay, remained in ICU for ≥24 hours before ICU discharge, and had 1-year of follow-up post-index ICU admission. Interventions: None. Measurements and Main Results: Of 20,659 patients, 25.0% lived in a rural setting at the time of their index ICU admission. Urban and rural ICU patients had similar baseline demographic characteristics, with differences in admitting location and discharge destination. Rural ICU patients were admitted to ICU from inpatient units less than urban patients (76.3%, 84.2%). Differences in discharge destination were also apparent, with rural ICU patients seeing a general practitioner as their first provider after hospital discharge (53.3%), while urban patients saw specialists (59.7%). Rural and urban ICU patients did not differ in their use of continuous renal replacement therapy, though rural ICU patients in the lowest quintile of material deprivation had lower odds of requiring mechanical ventilation during their ICU stay than their urban counterparts (OR: 0.87, 95% CI: 0.76-0.99). Rural ICU patients had greater odds of adverse events while in hospital (OR: 1.39, 95% CI: 1.09-1.78) and 30-day ICU readmission after hospital discharge compared to urban patients, regardless of social deprivation and sex. Conclusions: While critically ill patients living in urban and rural settings are similar at the time of ICU admission and have similar clinical courses in ICU, their care and outcomes differ after ICU discharge. Lack of access to care in rural areas may be related to these differences. Strategies to improve healthcare access in these areas are needed to ensure high-quality care for critically ill patients living in rural settings.

description: We have constructed a theory of dual canonical formalism to study the quantum competing systems. In such a system, as the relationship between current and voltage of each, we assumed the duality conditions. We considered competing system of two types. One type of these system are composed of the sandwich structure by SC(superconductor)/SI(superinsulator)/SC junction, and its dual junction is consists of the sandwich structure by SI/SC/SI junction. Another one type of these system is consists of the sandwich structure by SC/FM(ferromagnet)/SC junction. and its dual junction is consists of the sandwich structure by FM/SC/FM junction (spin Josephson junctions). We derived the relationship between the phase and the number of particles in a dual system of each other. As an application of the dual competitive systems, we introduced the quantum spin transistor.

description: Diamond has been proven to be a particularly useful material for implementing quantum technologies due to the various defects known as color centers. These color centers can be coupled to both photons and phonons; therefore, they enable the realization of a hybrid quantum system that consists of spins, photons, and phonons. Cavity optomechanics provides a platform to increase the interaction time between photons and phonons. By increasing the average number of photons and phonons, the coupling rates will be enhanced, and better control over the system could emerge as a result. This is integral to quantum technologies such as quantum networks, computers, and sensors. Cavity optomechanical systems are inherently nonlinear systems, which can be easily seen when the number of photons and phonons increases. This work studies nonlinear cavity optomechanics in diamond as we explore relatively under-studied dynamical regimes of optomechanical systems by increasing the number of phonons.

description: The pathway to achieving a sustainable, low-carbon power system includes the widespread integration of energy storage to tackle intermittency of renewable energy sources and provide stability to the grid through various grid services. Among the wide range of stationary energy storage technologies available, the lithium-ion battery dominates the growth in installations throughout the world. Although lithium-ion battery energy storage systems are complex grid assets with nonlinear characteristics and lifespans that depend on operating conditions, the majority of economic assessments are conducted using a simple energy reservoir model that does not consider the physical processes occurring inside the lithium-ion battery storage. This thesis focuses on the development of physics-based models for lithium-ion battery energy storage in power system techno-economic studies. The aim of this work is to assist developers and investors in making better-informed decisions. In this work, modelling approaches used to represent lithium-ion battery energy storage in power system operation and planning studies are reviewed. The role of advanced models in enhancing the accuracy of economic evaluations and producing feasible schedules for battery storage providing transmission-level services is discussed. More importantly, this work proposes three physics-based mixed-integer models for battery energy storage for use in power system operation research studies. The first model is based on the single particle model and replicates the nonlinear operational characteristics of the battery. This model can be used for short-term operation studies. The second proposed model combines the widely-used energy reservoir model with the physical description of solid electrolyte interphase formation as a degradation mechanism. This model has been tested for long-term studies in both energy and power grid applications. Finally, the third proposed model is a data-driven model that accurately reproduces the degradation processes and nonlinear performance of the lithium-ion cell. The model facilitates long-term assessment of battery energy storage and effectively tracks both capacity and power fade over time. The results obtained from all the models are validated using the digital twin, which is based on the single particle model.

description: Design reviews play a crucial role in the development process, ensuring the quality and effectiveness of designs in various industries. However, traditional design review methods face challenges in effectively understanding and communicating complex 3D models. Immersive technologies, particularly Head-Mounted Displays (HMDs), offer new opportunities to enhance the design review process. In this thesis, we investigate using immersive environments, specifically HMDs, for 3D design reviews. We begin with a systematic literature review to understand the current state of employing HMDs in industry for design reviews. As part of this review, we utilize a detailed taxonomy from the literature to categorize and analyze existing approaches. Additionally, we present four iterations of an immersive design review system developed during my industry experience. Two of these iterations are evaluated through case studies involving domain experts, including engineers, designers, and clients. A formal semi-structured focus group is conducted to gain further insights into traditional design review practices. The outcomes of these evaluations and the focus group discussions are thoroughly discussed. Based on the literature review and the focus group findings, we uncover a new challenge associated with using HMDs in immersive design reviews—asynchronous and remote collaboration. Unlike traditional design reviews, where participants view the same section on a shared screen, HMDs allow independent exploration of areas of interest, leading to a shift from synchronous to asynchronous communication. Consequently, important feedback may be missed as the lead designer disconnects from the users' perspectives. To address this challenge, we collaborate with a domain expert to develop a prototype that utilizes heatmap visualization to display 3D gaze data distribution. This prototype enables lead designers to quickly identify areas of review and missed regions. The study incorporates the Design Critique approach and provides valuable insights into different heatmap visualization variants (top view projection, object-based, and volume-based). Furthermore, a list of well-defined requirements is outlined for future spatio-temporal visualization applications aimed at integrating into existing workflows. Overall, this thesis contributes to the understanding and improvement of immersive design review systems, particularly in the context of utilizing HMDs. It offers insights into the current state of employing HMDs for design reviews, utilizes a taxonomy from the literature to analyze existing approaches, highlights challenges associated with asynchronous collaboration, and proposes a prototype solution with heatmap visualization to address the identified challenge.

description: Critical power (CP) represents an important threshold for exercise performance and fatiguability. We sought to determine the extent to which biological sex, hemoglobin mass (Hbmass), skeletal muscle mitochondrial content and fibre type influences CP. Prior to CP determination (i.e., 3-5 constant work rate trials to task failure), Hbmass was measured and vastus lateralis muscle biopsy samples were collected from 12 females and 12 males matched for aerobic fitness (V̇O2max: 59.2±7.7 vs. 59.5±7.1 mL·kg FFM-1·min-1). Males had a significantly greater CP than females when expressed in absolute terms (p=0.001), but there was no sex difference when expressed relative to BM (P=0.267) or FFM (p=0.622). Males had significantly greater W’ in absolute units (p<0.001), relative to BM (p=0.001), and relative to FFM (p=0.016). Males also had a significantly greater Hbmass in absolute units (p<0.001), relative to BM (p<0.001), and relative to FFM (p=0.016). There was no sex difference in mitochondrial content (p=0.375) or MHC I (p=0.574) proportionality. Whether CP was expressed in absolute (W) or relative units (W·kg BM-1 or W·kg FFM-1), there were significant positive correlations between CP and Hbmass (0.436≤r≤0.695; p<0.05) and mitochondrial content (0.413≤r≤0.708; p<0.05). There were significant positive correlations between relative CP (W·kg BM-1 or W·kg FFM-1) and MHC I proportionality (0.506≤r≤0.585; p<0.05). Overall, there was no sex difference in relative CP when males and females were matched for aerobic fitness, and variability in CP was related to Hbmass, mitochondrial content, and MHC I proportionality. The extent to which manipulations in these parameters influence CP warrants further investigation.

description: Bacterial vaginosis (BV) is the most common vaginal condition to prompt healthcare, impacting 80% of women at some point in their lifetime. Although treatable with antimicrobials, BV is hallmarked by high rates of recurrence due the involvement of a tissue-adherent biofilm dominated by Gardnerella species. Limited species-level information on BV biofilms is available, as the taxonomic grouping formerly referred to as a single species, Gardnerella vaginalis, was recently emended to define a genus (Gardnerella) with three newly named species and up to 7 yet-unnamed genomospecies. Cataloguing the differences between newly discovered genomospecies has become a research priority, but there is still a lack of optimized protocols for growing and phenotyping these organisms in liquid culture conditions. Thus, the first major objective of this thesis was to identify a culture medium capable of supporting robust growth and condition-matched phenotyping of Gardnerella genomospecies. My results showed that the growth medium PYG-mod, when supplemented with heat inactivated human serum, optimally supported the growth of diverse Gardnerella genomospecies and promoted biofilm development. I further established a unique OD600 based methodology that quantifies the fraction of culture biomass that is adherent (biofilm), non-adherent (planktonic), and loosely adherent in a high throughput 96-well plate format. Using the OD600 based methodology in conjunction with traditional safranin staining, I showed that all Gardnerella genomospecies tested were strong biofilm producers and differences in the genomospecies’ ability to form biofilms are minimal when accounting for the high degree of phenotypic variance across biological replicates that is probably caused by this clade’s strong propensity for phase variation. The next objective of this thesis was to quantify each genomospecies’ intrinsic resistance to metronidazole and observe if antibiotics can affect biofilm development. Using liquid culture MIC50 experiments and a new OD600 based method, I showed that Genomospecies 07 may have higher intrinsic resistance to metronidazole and that metronidazole exposure does not affect biofilm development of any genomospecies. Together, these experiments have advanced our understanding of Gardnerella genomospecies and will allow for improved experimental design and more appropriate interpretation of future in vitro studies that may wish to assess their phenotypic differences to determine whether certain genomospecies may be linked to BV treatment success, failure, or recurrence.
The Bias of Using Cross-Validation in Genomic Predictions and Its Correction

description: Cross-validation (CV) is a widely used technique in statistical learning for model evaluation and selection. Meanwhile, various of statistical learning methods, such as Generalized Least Square (GLS), Linear Mixed-Effects Models (LMM), and regularization methods are commonly used in genomic predictions, a field that utilizes DNA polymorphisms to predict phenotypic traits. However, due to high dimensionality, relatively small sample sizes, and data sparsity in genomic data, CV in these scenarios may lead to an underestimation of the generalization error. In this work, we analyzed the bias of CV in eight methods: Ordinary Least Square (OLS), GLS, LMM, Lasso, Ridge, elastic-net (ENET), and two hybrid methods: one combining GLS with Ridge regularization (GLS+Ridge), and the other combining LMM with Ridge regularization (LMM+Ridge). Leveraging genomics data from the 1,000 Genomes Project and simulated phenotypes, our investigation revealed the presence of bias in all these methods. To address this bias, we adapted a variance-structure method known as Cross-Validation Correction (CVc). This approach aims to rectify the cross-validation error by providing a more accurate estimate of the generalization error. To quantify the performance of our adapted CVc towards all these methods, we applied the trained model to an independently generated dataset, which served as a gold standard for validating the models and calculating the generalization error. The outcomes show that, by leveraging CVc, we corrected the CV bias for most of the methods mentioned above, with two exceptions that are unrectifiable methods: ENET and Lasso. Our work revealed the substantial bias in the use of CV in genomics, a phenomenon under-appreciated by the field of statistical genomics and medicine. Additionally, we demonstrated that bias-corrected models may be formed by adapting CVc, although more work is needed to cover the full spectrum.

description: Karl Popper had proposed an experiment to test the standard interpretation of quantum mechanics. The proposal survived for many year in the midst of no clear consensus on what results it would yield. The experiment was realized by Kim and Shih in 1999, and the apparently surprising result led to lot of debate. We review Popper's proposal and its realization in the light of current era when entanglement has been well studied, both theoretically and experimentally. We show that the "ghost-diffraction" experiment, carried out in a different context, conclusively resolves the controversy surrounding Popper's experiment.

A computationally efficient method for solving Min system reaction-diffusion equations within growing and dividing domains that approximate a rod-shaped bacterium
Creators: name: Carlquist, William Christopher
Publisher: name: University of British Columbia
Year: 2012

description: Few biological systems, showing complex pattern formation that spans multiple spatial and temporal scales, have been reduced in understanding to several components. The Min system in Escherichia coli, consists of three proteins, MinD, MinE, and MinC. Through ordered, cyclic, membrane binding and unbinding, facilitated by ATP hydrolysis, the Min system regulates the site of cell division in vivo. The Min system is tightly coupled with cell growth and division. Various mathematical models have been proposed to describe specific biological phenomena, arising from the Min system, but no model has been tested in a biologically relevant space, which grows and divides. In this thesis, I develop a computationally efficient method for solving reaction-diffusion equations, in a growing and dividing geometry, which approximates growth and division in a rod-shaped bacterium.

description: Failing to understand the lessons of war can cause militaries to repeat past failures, leading to increased costs in terms of resources and causalities in future conflicts. Modern Western militaries faced a range of difficulties on the battlefields of Iraq and Afghanistan that they struggled to address, and they need to learn and institutionalize the lessons of their experiences if they are to succeed in future conflicts. This dissertation addresses this by asking: to what extent has the battlefield experience of the U.S. military influenced post-war organizational change? The various service branches of the U.S. military have needed to adapt at the tactical, operational, and strategic levels of war. However, what remains to be understood is if, and more importantly how, such battlefield adaptations and the lessons of military operations were actually learned and thus influenced the overall organizational changes of the U.S. military. This dissertation examines whether battlefield adaptations of the U.S. Army, Air Force (then the Army Air Force), Navy and Marine Corps during the Second World War influenced the process of post-war organizational change within the military in the aftermath of that conflict. In particular, this dissertation explores the role of junior and midlevel officers in the change process, which is an area of focus that has been largely undervalued by much of the existing literature on military change. Building on archival research, this dissertation develops a framework to explain the process of how the lessons of combat become institutionalized in a post-war period.

description: Correlation functions of matrix-valued fields are not generally known for massive renormalized field theories. We find the large-N limit of form factors of the (1+1)-dimensional sigma model with SU(N) X SU(N) symmetry. These form factors give a correction to the free-field approximation for the N=infinity Wightman function. The method is a combination of the 1/N-expansion of the S-matrix and Smirnov's form-factor axioms. We expand the renormalized field in terms of a free massive Bosonic field as N goes to infinity.

Application of Lattice Boltzmann Method for Simulating Stably Stratified Flows past Cylinders
Creators: name: Maddahi, Navid
Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Engineering--Civil

description: This research looks into the intriguing subject of ambient density-stratified flows, which have long captivated researchers due to their representation of real-world physical phenomena such as diapycnal mixing in oceans driven by environmental influences. The study specifically focuses on the flow past a cylindrical object within such stratified flows, which introduces complexities involving buoyancy and viscous effects. A major focus of this research is the examination of the lattice Boltzmann method as a novel approach to model stratified flows around circular cylinders by solving coupled Navier-Stokes and advection-diffusion equations. The study investigates the impact of stratification on wake characteristics and various flow parameters for a single cylinder at six Reynolds numbers ranging from 10 to 600 and Froude numbers from 2.19 to 7.51. Additionally, the investigation includes the case of two cylinders arranged in tandem at a Reynolds number of 100, with similar Froude numbers. This research demonstrates the suitability and robustness of the lattice Boltzmann method in modeling stratified flows past cylinders. The findings reveal that even moderate levels of stratification can significantly influence the wake pattern, potentially leading to changes in the flow regime. Moreover, the study demonstrates that the introduction of stratification is associated with a reduction in the drag coefficient and shedding frequency, leading to altered flow behaviors. Furthermore, in the case of flow past two cylinders, the presence of stratification increases the critical spacing between the cylinders.

description: As a simple extension, a non-Abelian family gauge symmetry SO(3), as well as three family Majorana neutrinos, was introduced to explain the tri-bimaximal mixing matrix of neutrinos. We discuss the effect of the possible SO(3) family gauge interaction to the mass differences of $K-\bar{K}$, $B_d-\bar{B}_d$, $B_s-\bar{B}_s$ and $D-\bar{D}$, and get the constrains to the new gauge bosons.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We analyze the bounds on the spectrum of composite Higgs models (CHM) that come from flavor observables, by means of simple two-site effective Lagrangians, which incorporate a custodial symmetry and a Left-Right parity and which could also be adopted in further phenomenological studies on CHM. We derive, in particular, an important constraint on the masses of the $(t_L, b_L)$ partners, which does not depend on the flavor structure of the sector beyond the SM. This bound is obtained from the "infrared" contribution to $b \to sγ$ induced by the flavor-conserving effective vertex $Wt_Rb_R$. We find that the presence of a custodial symmetry can play a role in protecting this effective coupling and, as a consequence, in attenuating the constraint, which, however, remains of the order of 1 TeV. In addition to this bound, we calculate the constraints from the "ultraviolet" contribution to $b \to s γ$, induced by loops of heavy fermions, and to $ε^{'}/ε_K$.

description: In this paper, we explore the cosmological implications of interacting dark energy model in a torsion based gravity namely $f(T)$. Assuming dark energy interacts with dark matter and radiation components, we examine the stability of this model by choosing different forms of interaction terms. We consider three different forms of dark energy: cosmological constant, quintessence and phantom energy. We then obtain several attractor solutions for each dark energy model interacting with other components. This model successfully explains the coincidence problem via the interacting dark energy scenario.

FLYING SAUCER 1 is a transmembrane RING protein involved in cell wall biosynthesis in the Arabidopsis thaliana seed coat
Creators: name: Voiniciuc, Catalin
Publisher: name: University of British Columbia
Year: 2012

description: The plant cell wall is a complex and dynamic network of polysaccharides and structural proteins, which lies outside the plasma membrane and provides strength and protection. The mechanical properties of the cell wall depend largely on the structure and organization of its components. Pectins form the gel matrix in which all other wall components are embedded and changes in their degree of methylesterification (DM) impact wall strength and adhesion. Low DM pectin molecules can be linked together via calcium bridges to form strong gels, but very few mutants affecting pectin methylesterification have been identified. During my MSc research, I characterized flying saucer 1 (fly1), a novel Arabidopsis thaliana seed coat mutant, which displays primary cell wall detachment, reduced mucilage extrusion, and increased mucilage adherence. These defects appear to result from a lower DM in mucilage, and can be intensified by addition of Ca²⁺ ions or completely rescued by treatment of seeds with cation chelators. The FLY1 gene encodes a protein with multiple transmembrane spans that is targeted to the secretory pathway and contains a RING-H2 domain, which generally facilitates protein-protein interactions. FLY1-YFP fusion proteins localize to small intracellular compartments in seed coat epidermal cells at the stage of mucilage biosynthesis. TUL1, a previously described FLY1 yeast ortholog, is a Golgi-localized E3 ligase involved in the trafficking of membrane proteins. I propose that FLY1 promotes pectin methylesterification in seed coat epidermal cells, potentially through interactions with pectin methyltransferase enzymes in the Golgi apparatus. Co-expression analysis suggests that FLY1 and FLY2, its only paralog, may play partially redundant roles in xylem development. These genes may be regulated by KNAT7, a transcription factor that controls secondary wall biosynthesis in both xylem and seed coat cells. The binding partners of the FLY1 protein and its precise molecular function remain to be determined.

description: Carbon fiber is a lightweight, high tensile strength, and high modulus material extensively employed in diverse industries such as aerospace, automotive, and energy. Its production involves the utilization of various precursors tailored to specific applications, based on desired mechanical properties. However, the widespread adoption of carbon fiber is hindered by manufacturing costs and associated emissions. Notably, the pre-treatment of precursors, melt spinning, stabilization, carbonization, and graphitization steps contribute significantly to costs, energy consumption, and greenhouse gas emissions. Consequently, there is a need for cost-effective processing techniques to meet the increasing demand for carbon fiber. This research focuses on the use of asphaltene derived from Alberta oil sands as a low-cost alternative precursor, specifically exploring the graphitization step in carbon fiber manufacturing. In the conventional method, graphitization is conducted using a furnace between 2000 °C and 3000 °C. In this study, the potential use of laser technology as an alternative heat treatment source is proposed due to its rapid and high energy generation capabilities. Laser treatment generates energy measured above 2000 °C using a pyrometer, by adjusting scan speed, laser power, and treatment direction, different temperature profiles are obtained. Graphitized asphaltene-based carbon fiber exhibits an enhanced strength-to-weight ratio, improved thermal stability, increased mechanical stiffness, higher corrosion resistance, and enhanced electrical conductivity. X-ray diffraction analysis is employed to understand crystalline growth and interlayer spacing (d002), while Raman spectroscopy provides insight into chemical structure transitions on the fiber surface. Scanning electron microscopy (SEM) is utilized to observe surface morphology pre- and post-laser treatment at a microscopic level. Electrical conductivity tests are conducted to evaluate the impact of laser treatment on the carbon fiber's electrical resistivity. Additionally, mechanical testing is employed to assess the strength of laser-treated carbon fiber. Multiphysics finite element analysis is utilized for modeling laser treatment, allowing an understanding of the required temperature (above 2000 °C) represented by a distributed heat flux on the fiber's surface. This study explores alternative and cost-effective manufacturing approaches for carbon fiber by utilizing asphaltene as a precursor and employing laser technology for the graphitization process. The results offer valuable insights into the structural and performance enhancements achieved, facilitating carbon fiber production technique advancements.
Critical Point Estimation and Long-Range Behavior in the One-Dimensional XY Model Using Thermal Quantum and Total Correlations

description: We investigate the thermal quantum and total correlations in the anisotropic XY spin chain in transverse field. While we adopt concurrence and geometric quantum discord to measure quantum correlations, we use measurement-induced nonlocality and an alternative quantity defined in terms of Wigner-Yanase information to quantify total correlations. We show that the ability of these measures to estimate the critical point at finite temperature strongly depend on the anisotropy parameter of the Hamiltonian. We also identify a correlation measure which detects the factorized ground state in this model. Furthermore, we study the effect of temperature on long-range correlations.
