Topological Quantum Statistical Mechanics and Topological Quantum Field Theories

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: In this work, we first focus on the mathematical structure of the three-dimensional (3D) Ising model. In the Clifford algebraic representation, many internal factors exist in the transfer matrices of the 3D Ising model, which are ascribed to the topology of the 3D space and the many-body interactions of spins. They result in the nonlocality, the nontrivial topological structure, as well as the long-range entanglement between spins in the 3D Ising model. We review briefly the exact solution of the ferromagnetic 3D Ising model at the zero magnetic field, which was derived in our previous work. Then, the framework of topological quantum statistical mechanics is established, with respect to the mathematical aspects (topology, algebra, and geometry) and physical features (the contribution of topology to physics, Jordan-von Neumann-Wigner framework, time average, ensemble average, and quantum mechanical average). This is accomplished by generalizations of our findings and observations in the 3D Ising models. Finally, the results are generalized to topological quantum field theories, in consideration of relationships between quantum statistical mechanics and quantum field theories. It is found that these theories must be set up within the Jordan-von Neumann-Wigner framework, and the ergodic hypothesis is violated at the finite temperature. It is necessary to account the time average of the ensemble average and the quantum mechanical average in the topological quantum statistical mechanics and to introduce the parameter space of complex time (and complex temperature) in the topological quantum field theories. We find that a topological phase transition occurs near the infinite temperature (or the zero temperature) in models in the topological quantum statistical mechanics and the topological quantum field theories, which visualizes a symmetrical breaking of time inverse symmetry.

description: Segmentation of osseous structures from clinical MR images has remained a challenging task for many years now due to inevitable acquisition artifacts and inhomogeneous intensity of bones. To come up with the associated challenges, we devised a novel parametric deformable model framework for segmentation of 3D magnetic resonance (MR) images in computer-aided diagnosis (CAD) of cam type femoro-acetabular impingement (FAI). Our framework has two phases: (i) we introduce radial basis function (RBF) interpolation for semi-automatic piecewise registration of a proximal femur atlas model to the region of interest (ROI) using landmarks displacements and (ii) a parametric deformable model for coarse-to-fine level segmentation based on acting internal and external forces. We tested our segmentation scheme on a 3D synthetic image data as well as clinical datasets of MR hip images with different resolutions and validated the results of real data in comparison with three related parametric deformable model techniques. Accordingly, we found our methodology to be robust against artifacts and intensity inhomogeneity existing in high and low-resolution images and relatively resistant to under- and over- segmentation problems.

description: An understanding of relationships between different constructs of the neighbourhood environment and diet quality is needed to inform public health interventions. This study investigated associations between material deprivation, social deprivation and population density with diet quality in a cohort of 19,973 Canadian adults aged 35 to 69 years within the Atlantic PATH cohort study. Diet quality, a metric of how well diet conforms to recommendations was determined from a 24-item food frequency questionnaire. Neighbourhood environment data were derived from dissemination area level Census data. Two deprivation indices were evaluated: material and social deprivation, which reflect access to goods and amenities and social relationships. Multi-level models were used to estimate relationships (mean differences and 95% CI) between neighbourhood environment and diet quality, adjusting for covariates. Mean diet quality was lower in the most socially deprived neighbourhoods compared to the least socially deprived: −0.56, 95% CI (−0.88, −0.25). Relationships between diet quality and population density differed between urban and rural areas (p-interaction < 0.0001). In rural areas, diet quality was higher in intermediate-density neighbourhoods: 0.54, 95% CI (0.05, 1.03). In urban areas, diet quality was lower in intermediate-density and the most-dense neighbourhoods: −0.84, 95% CI (−1.28, −0.40) and −0.72, 95% CI (−1.20, −0.25). Our findings suggest socially deprived and high-density neighbourhoods are associated with lower diet quality and possible urban-rural differences in neighbourhood environment-diet quality relationships. Additional studies are needed to determine the temporal nature of relationships and whether differences in diet quality are meaningful.

description: The Hubble tension has become one of the central problems in cosmology. In this work, we determine the Hubble constant $H_0$ and sound horizon $r_d$ by using the combination of Baryon Acoustic Oscillations (BAOs) from DESI surveys, time-delay lensed quasars from H0LiCOW collaborations and the Pantheon supernovae observations. We consider two cosmological approaches, i.e., Taylor series and Padé polynomials, to avoid cosmological dependence. The reason for using this combination of data is that the absolute distance provided by strong gravitational lensing helps anchor the relative distance of BAO, and supernovae provide a robust history of universe evolution. {{Combining the 6 time-delay distance (6$D_{Δt}$) plus 4 angular diameter distance to the deflector (4$D_d$) measurements of time-delay lensed quasars,}} the BAO and the type Ia of supernovae (SNe Ia) datasets, we obtain a model-independent result of $r_d = 138.2_{-3.9}^{+3.3}$ Mpc and $H_0 = 72.9^{+1.8}_{-1.8}$ ${\mathrm{~km~s^{-1}~Mpc^{-1}}}$ for the Taylor series cosmography and $r_d = 137.0_{-3.7}^{+3.2}$ Mpc and $H_0 = 73.1_{-1.7}^{+1.8}$ ${\mathrm{~km~s^{-1}~Mpc^{-1}}}$ for the Padé polynomials cosmography. The determination of $r_d$ and $H_0$ prefers larger $H_0$ and smaller $r_d$ than Planck data under the assumption of flat-$Λ$CDM model. However, the values of $H_0$ are consistent with the $H_0$ determination from SH0ES collaboration.

description: Bacteriophages (hereafter referred as phages) can translate their mRNAs efficiently by maximizing the use of codons decoded by the most abundant tRNAs of their bacterial hosts. Translation efficiency directly influences phage fitness and evolution. Reengineered phages find application in controlling their host population in both health and industry. The objective of this thesis work is to examine the factors shaping codon choices of single stranded DNA (ssDNA) and double stranded DNA (dsDNA) Escherichia coli phages. In chapter two, we employed two indices, rRSCU (correlation in relative synonymous codon usage between phages and their hosts) and CAI (codon adaptation index) to measure codon adaptation in phages. None of the analyzed ssDNA phages encode tRNAs while some dsDNA phages encode their own tRNAs. Both rRSCU and CAI are negatively correlated with number of tRNA genes encoded by these dsDNA phages. We observed significantly greater rRSCU for dsDNA phages (without tRNAs) than ssDNA phages. In addition, we propose that ssDNA phages have evolved a novel codon adaptation strategy to overcome the disruptive effect of their high C→T mutation rates in codon adaptation with host. In chapter three, we formulated an index phi to measure selection by host translation machinery and to present explicit linear and nonlinear models to characterize the effect of C→T mutation and host-tRNA-mediated selection on phage codon usage. The effect of selection (phi) on codon usage is detectable in most dsDNA and ssDNA phage species. C→T mutations also interfere with nonsynonymous substitutions at second codon positions, especially in ssDNA phages. Strand asymmetry along with the accompanying local variation in mutation bias can significantly affect codon adaptation in both dsDNA and ssDNA phages.

description: Antibiotic resistance is a major threat to public health. Understanding how it evolves, and the genes that underlie resistance, is the main goal of my Ph.D. research. After a resistance mutation arises, it’s fate within a pathogen population will be etermined in part by its fitness: mutations that suffer little or no fitness cost are more likely to persist in the absence of antibiotic treatment. My research centers on understanding this process better by gaining knowledge about the spectrum of fitness effects associated with antibiotic resistance mutations. Using a meta-analysis framework I find that, across a range of antibiotics and pathogens, on average single resistance mutations exhibit fitness costs in the absence of drug, however, there are instances of cost-free mutations. To evaluate the conditions leading to the persistence of resistance in the absence of antibiotic, I use experimental evolution of the opportunistic pathogen Pseudomonas aeruginosa and the antibiotic ciprofloxacin to investigate the phenotypic and genetic differences associated with constant and fluctuating drug treatment. I find that fluctuating drug treatment leads to the evolution of cost-free resistance. At the genetic level, cost-free resistance is the result of second-site mutations that compensate for the fitness cost associated with ciprofloxacin-resistance mutations. Further examination of the resistance mutations shows a lack of epistatic interactions between co-occurring mutations that confer resistance within a single isolate. To investigate the repeatability of the genetic causes of resistance, I execute a second evolution experiment using multiple clinical strains of P. aeruginosa adapting to a constant ciprofloxacin selective pressure. I find a remarkable lack of parallel evolution at the genomic level both within and between different P. aeruginosa strains. I have shown that antibiotic resistance is costly, and that these costs can be ameliorated by second-site mutations that readily arise over short time scales. Additionally, different strains of the same bacteria can gain resistance through a diverse set of genetic mutations. On an applied level these results are not positive; combating resistance evolution will be difficult because pathogens can easily compensate fitness costs of resistance, and resistance itself can be gained via a large number of genetic targets.

description: In a study we conducted with Ontarian women about their abortion experiences (OAS), one third of participants expressed a desire for post-abortion support. Yet, there is some anecdotal evidence to suggest that organizations offering these services are using judgmental frameworks. In order to rigorously investigate this, we explored what post-abortion support services are offered across the province of Ontario. This multi-methods study included an analysis of OAS data, creating a directory of post-abortion support services in the province, conducting an analysis of how these services represent themselves online, and carrying out mystery client interactions. We found that the majority of organizations offering post-abortion support services in Ontario are crisis pregnancy centers. The services offered at these organizations are built upon frameworks that are both shaming and stigmatizing of abortion experiences. Efforts to increase the online visibility and overall accessibility of non-judgmental, medically accurate post-abortion support services in Ontario appear warranted.

description: The removal of trace amounts of acetylene in ethylene streams is a high-volume industrial process that must possess high selectivity of alkyne hydrogenation over hydrogenation of alkenes. Current technology uses metallic nanoparticles, typically palladium or platinum, for acetylene removal. However, problems arise due to the deactivation of the catalysts at high temperatures as well as low selectivities at high conversions. Pore expanded MCM-41 is synthesized via a two-step strategy in which MCM-41 was prepared via cetyltrimethylammonium bromide (CTMABr) followed by the hydrothermal treatment with N,N-dimethyldecylamine (DMDA). This material was washed with ethanol to remove DMDA, or calcined to remove both surfactants. PE-MCM-41 based materials were impregnated with palladium, gold, and palladium-gold nanoparticles. The removal of DMDA had an effect on both the conversion and selectivity, in which they were found to drop significantly. However, by using the bimetallic PdAu catalysts, higher selectivity could be achieved due to increased electron density.

description: The concept of the ‘procurer’ comes from section 212 of Canada’s Criminal Code, which prohibits directing, enticing, assisting or profiting off the prostitution of another person. A contentious debate surrounds Canada’s prostitution laws, with a constitutional challenge currently before the Supreme Court. Within this climate of debate, the concept of the ‘procurer’ has moved out of the strictly legal sphere and into a broader discourse, with a range of parties laying their claims to truth on the “realities” of the industry generally and on the procurer specifically. Using a methodology of Foucauldian discourse analysis, this thesis examines Ontario Provincial Court case summaries to consider the contribution of the Canadian judiciary to discourse on the procurer. Findings suggest that the judiciary replicates many of the existing stereotypes of prostitution and its participants, such as the procurer as pimp, while (re)producing a small counter discourse of the procurer as business manager.

description: This report synthesizes findings from the November 2024 Community Workshop on Practical Reproducibility in HPC, which convened researchers, artifact authors, reviewers, and chairs of reproducibility initiatives to address the critical challenge of making computational experiments reproducible in a cost-effective manner. The workshop deliberately focused on systems and HPC computer science research due to its unique requirements, including specialized hardware access and deep system reconfigurability. Through structured discussions, lightning talks, and panel sessions, participants identified key barriers to practical reproducibility and formulated actionable recommendations for the community.
 The report presents a dual framework of challenges and recommendations organized by target audience (authors, reviewers, organizations, and community). It characterizes technical obstacles in experiment packaging and review, including completeness of artifact descriptions, acquisition of specialized hardware, and establishing reproducibility conditions. The recommendations range from immediate practical tools (comprehensive checklists for artifact packaging) to ecosystem-level improvements (refining badge systems, creating artifact digital libraries, and developing AI-assisted environment creation). Rather than advocating for reproducibility regardless of cost, the report emphasizes striking an appropriate balance between reproducibility rigor and practical feasibility, positioning reproducibility as an integral component of scientific exploration rather than a burdensome afterthought. Appendices provide detailed, immediately actionable checklists for authors and reviewers to improve reproducibility practices across the HPC community.

description: Starting a few decades ago, the unmanned wheeled vehicle research has drawn lately more attention, especially for off-road environment. As the demand to use electric vehicles increased, the need to conceptualize the use of electrically driven vehicles in autonomous operations became a target. That is because in addition to the fact that they are more environmentally friendly, they are also easier to control. This also gives another reason to enhance further the energy economy of those unmanned electric vehicles. Off-road vehicles research was always challenging, but in the present work the nature of the off-road land is utilized to benefit from in order to enhance the energy consumption of those vehicles. An algorithm for energy consumption optimization for electrically driven unmanned wheeled vehicles is presented. The algorithm idea is based on the fact that in off-road conditions, when the vehicle passes a ditch or a hole, the kinetic energy gained while moving downhill could be utilized to reduce the energy consumption for moving uphill if the dimensions of the ditch/hole were known a distance ahead. Two manipulated variables are evaluated: the wheels DC motors supply voltage and the DC armature current. The developed algorithm is analysed and compared to the PID speed iii controller and to the open-loop control of DC motors. The developed predictive controller achieved encouraging results compared to the PID speed control and also compared to the open-loop control. Also, the use of the DC armature current as a manipulated variable showed more noticeable improvement over using the DC input voltage. Experimental work was carried out to validate the predictive control algorithm. A mobile robot with two DC motor driven wheels was deployed to overcome a ditch-like hindrance. The experimental results verified the simulation results. A parametric study for the predictive control is conducted. The effect of changing the downhill angle and the uphill angle as well as the size of the prediction horizon on the consumed electric energy by the DC motors is addressed. The simulation results showed that, when using the proposed approach, the larger the prediction horizon, the lower the energy consumption is.

description: In the Brief History of Time Stephen Hawking was pessimistic about astronomers detecting primordial black holes (PBHs). He would not be the only distinguished scientist to underestimate the extraordinary power of new technology. In a related area Albert Einstein published the equations for microlensing, but wrote off their practicality. Perhaps they meant "during my lifetime." The amazing properties of PBHs, however, validate heroic efforts to detect them. If they exist, their niches in our current history of time include supplying dark matter to bind galaxies, offering a solution for the Hubble tension, and, as supermassive black holes, giving us quasars as far as the eye can see. This Research Note describes a search for PBHs in the Gaia archive. In spite of the high density of local dark matter, it was unsuccessful. Microlensing with the Rubin telescope is the tool at our disposal to open the asteroid window for PBH.

description: La présente thèse vise d’une part à dégager les éléments d’un programme de traduction et d’autre part à déterminer si certains éléments sont communs à plus d’un programme. L’étude pose comme hypothèse principale que, bien que chaque programme de traduction soit ancré dans un contexte culturel, social, politique et académique différent, il existe un tronc commun à la majorité des programmes. Sur le plan théorique, l’accent sera mis sur la définition des compétences qu’un traducteur doit avoir une fois son diplôme en main et sur les différents éléments compris dans un programme de traduction. Une autre hypothèse avancée est que les compétences et sous-compétences du traducteur sont à la base du programme et donc, une fois celles-ci bien définies, elles pourraient servir à uniformiser les programmes se fondant sur des écoles de pensées différentes. Sur le plan expérimental, une étude empirique et la comparaison de deux programmes universitaires qui fonctionnent dans deux contextes entièrement différents permettront de cerner les divers éléments d’un programme de traduction.

Nel caso del  restauro, poi,  non potranno mancare le indagini sul degrado, eventualmente estese nel tempo in forma di ‘monitorag­gio’. Denominatore comune sarà un atteggiamento di grande attenzione alla ‘realtà’ del monumento, quindi alla concretezza dell'architettura.

description: The present paper describes the initial results of the research “Integrated informative models to identify, appreciate and share urban and environmental heritage. Testing 3D interfaces for "cultural and geographic objects": architecture of information and computerized architecture”. The main purpose of this research is to expand the concept of "integrated informative models" by studying integrations and overlaps from different environments, taking into consideration both geographical (3D GIS) and web (3D Web and 3D WebGIS) space as well as Virtual Reality (VR) and Augmented Reality (AR). The research aims at identifying technological, procedural and operational systems, structured specifically for each individual case, to define technology with easily accessible (cheap and/or open source) instruments characterized by reliable data processing. Within this framework, various experimentations have been carried out on the area we were privileged to work in, the historical centre of Ascoli Piceno, using different paths/measuring scales and following the necessary organization of data.

Tout en débordant de péripéties captivantes et de gags pour divertir le (jeune) lecteur, ces albums font de nombreuses références à divers phénomènes paranormaux qui fascinaient Hergé : la voyance, l’hypnose, l’envoûtement et les objets volants non identifiés. Il s’agira d’analyser les modalités d’insertion de ces phénomènes paranormaux dans les albums du corpus, en précisant quels savoirs ils véhiculent principalement, en identifiant certaines de leurs sources et en dégageant tant leur fonction que leur effet sur le lecteur implicite. Nous suggérons que, conscient d’être devenu un façonneur de représentations collectives, l’Hergé de la maturité se veut un passeur de savoirs contestables et contestés, mais auxquels il porte foi.

description: We present high-resolution observations made with the Australia Telescope Compact Array (ATCA) at 5.5 GHz and 9.0 GHz of a sample of twenty-eight massive protostars. These protostars were initially detected at radio wavelengths in the MeerKAT Galactic Plane Survey at 1.3 GHz, where they were unresolved with an angular resolution of approximately 8 arcseconds. The resolution of the ATCA observations at 5.5 GHz and 9.0 GHz are significantly higher at, 2.0 and 1.2 arc seconds, respectively. The highest angular resolution corresponds to a linear resolution of 1920 AU for our nearest object. This improvement in resolution enabled us to resolve the components of extended emission and to more accurately determine the nature of the objects. Approximately 80% of the detections were classified as jets with 68% of the jets found to be associated with non-thermal emission.

description: The methylotrophic yeast Pichia pastoris has become an efficient expression system for heterologous protein production. Different methods have been studied to enhance cell growth as well as the production of products of interest. Two of the major strategies for improving the product or biomass yields are optimizing bioprocess controls and cultivation conditions. In this work, the characteristics of this yeast system and of its different promoters are discussed, and the effect of operational strategies on cell growth and recombinant protein expression is also studied. The effect of different feeding strategies were studied and optimized for pGAP (glyceraldehyde-3-phosphate dehydrogenase)-regulated phytase production in P. pastoris. Alternative carbon sources were screened and the feasibility of using citric acid as a carbon source for recombinant protein production was also investigated. The effects of parameters such as the carbon source concentration and culture pH were studied using shake-flasks, and the effect of different feeding profiles on bioreactor performance was also investigated. Three feeding strategies, Stepwise feeding, Exponential feeding and DO-stat feeding were tested and DO-stat was found to be more efficient and led to a high phytase activity. A modified DO-stat method was investigated to overcome the oxygen limited condition in the standard DO-stat method. For the carbon source, citric acid showed promise in improving phytase expression. Further experiments in bioreactors performed with the presence of certain amount of citric acid showed that less glycerol could be used to achieve the same level of phytase activity.

description: Runway and taxiway incursions continue to challenge aviation safety, as pilots often experience disorientation from poor visibility in adverse conditions and cognitive workload in complex airport layouts. Current tools, such as airport moving maps on portable tablets, allow manual route planning but do not dynamically adapt to air traffic controllers' (ATCOs) clearances, limiting their effectiveness in high-stress scenarios. This study investigates the impact of different input modalities - paper-based, keyboard touch, map touch, and speech-to-text - on taxiway navigation performance, using a medium-fidelity flight simulator and a Wizard-of-Oz methodology to simulate ideal automation conditions. Contrary to common assumptions, recent studies indicate that paper-based methods outperform digital counterparts in accuracy and efficiency under certain conditions, highlighting critical limitations in current automation strategies. In response, our study investigates why manual methods may excel and how future automation can be optimized for pilot-centered operations. Employing a Wizard-of-Oz approach, we replicated the full taxiing process - from receiving ATCO clearances to executing maneuvers - and differentiated between readback and execution accuracy. Findings reveal that speech-based systems suffer from low pilot trust, necessitating hybrid solutions that integrate error correction and confidence indicators. These insights contribute to the development of future pilot-centered taxiway assistance that enhance situational awareness, minimize workload, and improve overall operational safety.
Identification and Characterization of D-Amino Acid Aminotransferase Mutants Using Oxidase-coupled Assays

description: D-amino acid aminotransferase (DAAT) is a pyridoxal-dependent enzyme that catalyzes the formation of a variety of D-amino acids, making it an attractive biocatalyst for the production of enantiopure D-amino acids. To bolster its biocatalytic applicability, improved variants displaying increased activity towards non-native substrates are desired. In this work, we first developed a high-throughput, colorimetric, continuous coupled enzyme assay for the screening of DAAT mutant libraries that is based on the use of D-amino acid oxidase (DAAO). In this assay, the D-amino acid product of DAAT is oxidized by DAAO with concomitant release of hydrogen peroxide, which is detected colorimetrically by the addition of horseradish peroxidase and o-dianisidine. Using this assay, we identified three DAAT mutants (V33D, V33G and V33Y) displaying altered substrate specificity via the screening of cell lysates in 96-well plates. More specifically, the V33G and V33Y mutants display a ≈3-fold increase in kcat/KM for the non-native acceptor phenylpyruvate over wild type. Furthermore, we developed a coupled enzyme assay for the activity of DAAT with almost any D-amino acid using D-aspartate oxidase (DDO) as a coupling enzyme. Using this assay, we measured the specific activity of wild-type DAAT and the V33D, V33G, and V33Y mutants with 16 D-amino acid substrates. We demonstrate that the V33D, V33G, and V33Y mutants are more active than wild type with the aromatic substrates D-phenylalanine and 3-methyl-D-phenylalanine, while V33D and V33G are more active than wild type with D-valine, a branched chain amino acid. We expect the assays developed herein and subsequent mutants discovered to serve as valuable tools in the further development of biocatalysts for the production of enantiopure D-amino acids.

description: Women in low- and middle-income countries have high rates of perinatal depression. As smartphones become increasingly accessible around the world, there is an opportunity to explore innovative mHealth tools for the prevention, screening, and management of perinatal depression. We completed a scoping review of the literature pertaining to the use of mobile phone technologies for perinatal depression in low-and middle-income countries. PubMed CINHAL, and Google Scholar databases were searched, generating 423 results. 12 articles met our inclusion criteria. Two of the 12 articles reviewed mobile phone applications. The remaining 9 articles were study protocols or descriptive/intervention studies. Our results reveal that minimal literature is currently available on the use of mobile health for perinatal depression in low- and middle-income countries. We found four articles that present the results of an intervention that were delivered through mobile phones for the treatment of perinatal depressive symptoms and an additional qualitative study describing the perceptions of mothers receiving cognitive behavioral therapy via telephones. These studies demonstrated that depressive symptoms improved after the interventions. There is potential to improve the quality of mHealth interventions, specifically mobile phone applications for perinatal depressive symptoms and depression, through meaningful collaborative work between healthcare professionals and application developers.

description: We present an investigation of the L-band emission from known massive young stellar objects (MYSOs) in the SARAO MeerKAT Galactic Plane Survey to search for non-thermal radio emitters in the sample. A total of 398 massive protostars, identified from the Red MSX Source (RMS) survey, are located within the survey region. Among these, 162 fields that host the protostars are isolated from nearby bright HII regions, allowing for the study of any ionized jets present. Seventy-one of these fields have jets with five-sigma detections or higher, corresponding to a detection rate of 44%. The MeerKAT fluxes of the detections, together with the upper limits of the non-detections and any other fluxes from previous observations, were used to estimate the spectral indices of the jets, and to search for the presence of non-thermal radiation. In cases where a source manifests as single in a given observation but is resolved into multiple components in observations of higher resolutions, the sum of the fluxes of the resolved components was used in estimating the indices. Any e!ects from missing flux in higher-resolution observations were incorporated into the index uncertainties. The spectral indices of the sample show that at least 50% of the jets emit non-thermal radiation. Additionally, the spectral energy distribution (SED) of some of the sources, as well as their radio luminosities exhibit evidence of non-thermal emission, especially in extended sources.
