description: Using the works of Mañé \cite{Ma} and Paternain \cite{Pat} we study the distribution of geodesic arcs with respect to equilibrium states of the geodesic flow on a closed manifold, equipped with a $\mathcal{C}^{\infty}$ Riemannian metric. We prove large deviations lower and upper bounds and a contraction principle for the geodesic flow in the space of probability measures of the unit tangent bundle. We deduce a way of approximating equilibrium states for continuous potentials.

description: We employ the UrQMD transport + hydrodynamics hybrid model to estimate the effects of a separation of the hot equilibrated core and the dilute corona created in high energy heavy ion collisions. It is shown that the fraction of the system which can be regarded as an equilibrated fireball changes over a wide range of energies. This has an impact especially on strange particle abundancies. We show that such a core corona separation allows to improve the description of strange particle ratios and flow as a function of beam energy as well as strange particle yields as a function of centrality.

description: Human Resource Management has always, but much more nowadays, plays a decisive role in the effort made by the private and public sector and of course the Local Government, to respond to the diverse and growing demands and services, both in social and economic terms at technological level. In the narrow context of the procedures and functions of the local government processes and functions, this thesis examines the current situation of the Municipality of Acharnes and draws conclusions and proposals in all the functions of Human Resource Management. Its purpose is to investigate the importance and the way in which Local Government Organizations (OTAs) of the first degree manage the human resources they employ. In order to achieve the research objectives of the study, a quantitative primary survey was carried out on 180 workers-staff of the Municipality of Acharnes. For the needs of the research, a questionnaire was created that is addressed to all specialties and all positions available in the Municipality. The survey was conducted in January 2023 and the questionnaires were forwarded to the Municipality staff via e-mail. Survey data were analyzed with the SPSS 22.0 statistical program. The findings confirmed that the Municipality of Acharnes has several strengths and opportunities that upgrade it, but also several weaknesses and threats that it must use as motivation for improvement.

description: The aim of this paper is to provide cohomologies of $n$-ary Hom-Nambu-Lie algebras governing central extensions and one parameter formal deformations. We generalize to $n$-ary algebras the notions of derivations and representation introduced by Sheng for Hom-Lie algebras. Also we show that a cohomology of $n$-ary Hom-Nambu-Lie algebras could be derived from the cohomology of Hom-Leibniz algebras.

description: We present a low-energy effective field theory to describe the SO(n) bilinear-biquadratic spin chain. We start with n=6 and construct the effective theory by using six Majorana fermions. After determining various correlation functions we characterize the phases and establish the relation between the effective theories for SO(6) and SO(5). Together with the known results for n=3 and 4, a reduction mechanism is proposed to understand the ground state for arbitrary SO(n). Also, we provide a generalization of the Lieb-Schultz-Mattis theorem for SO(n). The implications of our results for entanglement and correlation functions are discussed.

Min- and Max-Entropy in Infinite Dimensions

Year: 2010
Subjects: subject: Quantum Physics (quant-ph)

description: We consider an extension of the conditional min- and max-entropies to infinite-dimensional separable Hilbert spaces. We show that these satisfy characterizing properties known from the finite-dimensional case, and retain information-theoretic operational interpretations, e.g., the min-entropy as maximum achievable quantum correlation, and the max-entropy as decoupling accuracy. We furthermore generalize the smoothed versions of these entropies and prove an infinite-dimensional quantum asymptotic equipartition property. To facilitate these generalizations we show that the min- and max-entropy can be expressed in terms of convergent sequences of finite-dimensional min- and max-entropies, which provides a convenient technique to extend proofs from the finite to the infinite-dimensional setting.

The collective margins : activating access within emerging digital landscapes
Creators: name: Lekei, Madelaine Maureen
Publisher: name: University of British Columbia
Year: 2022

description: Digital technologies, as many scholars articulate, are neither passive, neutral, nor isolated as they are embedded within political, social, and economic systems that contribute to uneven access and produce inequalities for the people who engage with and rely on digital mechanisms and tools (Burkell, Fortier, Wong, and Simpson 2014; Plesner and Phillips 2013; Baym and boyd 2012; Lievrouw 2011; Franklin 2011; Ito 2008). For disabled people, self-advocates, and their allies, digital spaces and tools provide critical opportunities to participate in telling their own stories, collectively learn from each other, engage in activism, and build supportive communities that may not be available in their immediate physical surroundings (Ginsburg 2012; Parr and Davidson 2010). Access is a core component that defines how people interact with and in digital spaces, which underscores the importance of gaining insights into how disabled people are working together to improve digital accessibility. Considering this reality, coupled with the ongoing complexities of COVID-19 that have necessitated a reliance on digital mechanisms, it is crucial to ensure that digital spaces and resources are designed in an accessible manner so that disabled people can equitably participate within and through the digital mechanisms in their daily lives. Through a digital ethnographic approach informed by feminist and crip theory as well as the principles of community engaged research and Disability Justice, this thesis garners critical insights into how disabled individuals, self-advocates, and their allies are collaborating to develop, improve, and encourage more equitable access and practices within digital environments. By following the digital and networked experiences of fourteen individuals who identify with various forms of disability, this thesis explores how the daily activities within digital spaces become the means through which disabled people reimagine identity, kinship, community, equitable democratic assembly, meaningful civic participation, accessible movement building, and disability world making in North America today.

description: Several constructions, of stringy origins or not, generate abelian gauge extensions of the Standard Model (SM). Even if the particles of the SM are not charged under this extra $U'(1)$, one cannot avoid the presence of a kinetic mixing between $U'(1)$ and the hypercharge $U_Y(1)$. In this work, we constraint drastically this kinetic mixing, taking into account the recent experimental data from accelerator physics, direct detection and indirect detection of dark matter. We show that the region respecting WMAP and experimental constraints is now very narrowed along the pole line where $M_{Z_D}\simeq 2 m_{DM}$, $Z_D$ being the gauge boson associated to the extra $U'(1)$.

Strongly Coupled Perturbations in Two-Field Inflationary Models

description: We study models of inflation with two scalar fields and non-canonical kinetic terms, focusing on the case in which the curvature and isocurvature perturbations are strongly coupled to each other. In the regime where a heavy mode can be identified and integrated out, we clarify the passage from the full two-field model to an effectively single-field description. However, the strong coupling sets a new scale in the system, and affects the evolution of the perturbations as well as the beginning of the regime of validity of the effective field theory. In particular, the predictions of the model are sensitive to the relative hierarchy between the coupling and the mass of the heavy mode. As a result, observables are not given unambiguously in terms of the parameters of an effectively single field model with non-trivial sound speed. Finally, the requirement that the sound horizon crossing occurs within the regime of validity of the effective theory leads to a lower bound on the sound speed. Our analysis is done in an extremely simple toy model of slow-roll inflation, which is chosen for its tractability, but is non-trivial enough to illustrate the richness of the dynamics in non-canonical multi-field models.

Beyond finders keepers : bioprospecting, patents and human genetic materials
Creators: name: Eze, Chinenye Helen
Publisher: name: University of British Columbia
Year: 2022

description: From time immemorial, developing countries have used biodiverse genetic resources as drugs, food, and treatments. In the 1980s, bioprospecting became the new “gold rush.” Developed countries targeted developing countries rich in biodiverse resources and collected genetic resources in most cases without informed consent or benefit sharing agreements. The illegal collection and use of genetic materials (including human genetic materials) led to outcries of biopiracy from developing countries. This biopiracy continues today. Some international laws were passed to regulate bioprospecting. The Convention of Biological Diversity (CBD), which entered into force in 1993, was the first international law to regulate bioprospecting. The Bonn Guidelines were passed in 2002 to regulate the implementation of the CBD. In 2010 the Nagoya Protocol to the CBD was passed to protect the traditional knowledge of Indigenous peoples. These regulations have two significant shortcomings. First, the current law does not address the bioprospecting of human genetic materials. Second, the law does not address misappropriation through patents. This work will address these issues. Using doctrinal and comparative research methodologies, this work will reach the following findings. First, bioprospecting applies to human genetic materials through population studies of targeted developing and Indigenous communities. Second, there are no laws to regulate the bioprospecting of human genetic materials. Third, the current national and international laws do not address the challenge of patent misappropriation. Fourth, the main proposal debated by developing countries is the “disclosure of source of origin’ requirement. Lastly, the enforcement of the disclosure requirement is unharmonized; there are disagreements on what to disclose, how to disclose, and how to infuse the disclosure requirement into patent laws. Ultimately, this work proposes to address the problem of misappropriation of human genetic materials through patents by re-imagining aspects of the TRIPS Agreement. In building this argument, it will rely on both critical IP theory and theories of new constitutionalism.
Detecting Clonal Structural Alterations from Multi-regional Profiling of Malignant Pleural Mesotheliomas

description: Malignant Pleural Mesothelioma (MPM) is a pleural tumour associated with asbestos exposure. There is a long latency period of 30-40 years between asbestos exposure and disease presentation, highlighting an unknown evolutionary trajectory. Throughout the latent years, different somatic genomic lesions are acquired by the growing tumour. In contrast to other malignancies, MPMs display modest single nucleotide mutational burden but a high frequency of structural alterations, in particular large-scale chromosomal losses. In this thesis, I explore how multiregional sequencing data can shed light into inter- and intra-tumour heterogeneity of MPM, as well as the various cellular processes shaping the tumour evolution. I investigated the mutational diversity between different resected sites within individual tumours, as well as between MPMs in order to infer genomic alterations that occurred during early tumour evolution and potential clonal drivers of tumour development. The existence of branched tumour evolution and widespread heterogeneity in MPMs was demonstrated: Copy number analysis revealed recurring truncal large-scale (aneuploidy level) and the focal losses of the tumour suppressor genes BAP1, PTPN13, FBXW7, CTCLT1, NF2, MYH9, EP300 and oncogenes NSD2, TEC and MTOR. Targeted sequencing of the recurring truncal losses of 1p36, 3p21 and 9p21 was used to attempt to identify deletion breakpoints. Gene fusion analysis revealed the extent of chromosomal rearrangements in MPM tumours, as well as the formation of potentially important fusions such as the potentially oncogenic CACNA1D-ERC2 fusion, in-frame PARD3BSTAB1 fusion, and intergenic fusions resulting in BAP1 and MTAP truncation. Finally, by analysis of gene fusion breakpoints, non-homologous end joining and alternative endjoining were revealed to be the likely structural mechanisms generating early extensive chromosomal rearrangements, in conjunction with truncal losses in homologous recombination and Hippo pathway genes. These truncal genomic alterations are likely to exist throughout the tumour, and potentially drive cancer progression, as they include mesothelioma associated genes, oncogenes, and tumour suppressor genes. Thus, identifying them highlights potential Achilles’ heels for drug targeting and treatment.

description: The quantification of quantum correlations (other than entanglement) usually entails laboured numerical optimization procedures also demanding quantum state tomographic methods. Thus it is interesting to have a laboratory friendly witness for the nature of correlations. In this Letter we report a direct experimental implementation of such a witness in a room temperature nuclear magnetic resonance system. In our experiment the nature of correlations is revealed by performing only few local magnetization measurements. We also compare the witness results with those for the symmetric quantum discord and we obtained a fairly good agreement.

description: We discuss carefully the blackbody approximation, stressing what it is (a limit case of radiative transfer), and what it is not (the assumption that the body is perfectly absorbing, i.e. black). Furthermore, we derive the Planck spectrum without enclosing the field in a box, as is done in most textbooks. Athough convenient, this trick conceals the nature of the idealization expressed in the concept of a blackbody: first, the most obvious examples of approximate blackbodies, stars, are definitely not enclosed in boxes; second, the Planck spectrum is continuous, while the stationary modes of radiation in a box are discrete. Our derivation, although technically less elementary, is conceptually more consistent, and brings the opportunity to introduce to students the important concept of local density of states, via the resolvent formalism.

Developing museum and exhibition design through practice-centred study and application of narrative theory and film
Creators: name: Duncan, Thomas R. A.
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: This research sets out to better understand and develop narrative in the design of narrative experiences in museum and exhibitions drawing on theories and knowledge of narrative structures in fiction films. Although there is emerging literature on the general role of narrative in the context of museum exhibitions, little has been written about refining design processes for contemporary narrative exhibition experiences. I address this gap from two distinct vantage points. Firstly, how could and should theoretical and structural understandings of narrative drawn from the study of fiction films be used to inform the design task? Through analysing and diagramming the sequencing, rhythm, and timing as well as action performed by the protagonists in specific examples of fiction films, I draw comparisons to the productive possibilities of narrative structures within exhibitions. Secondly, by thinking deeply about possible disjunctions between narrative as imagined by the design team and narrative experienced by the visitors, how might the outcomes of narrative-oriented design decisions be usefully assessed and this knowledge fed back into future design tasks? A central part of the methodology is a piece of visitor research where the experiences of real visitors were tracked with wearable cameras. An understanding of narrative in film can enable the designer to identify key thresholds and moments of decision in the embodied, temporal structure of the museum visit. Probing deeper into the workings of narrative the process of diagramming action in film evolved into an approach to identify action in exhibition content and investigate design methodologies to make it accessible for the visitor. Also engaging with visitors on site revealed how design should create spaces for everyday moments with an awareness of the visitor’s open interpretive possibilities. A practical outcome of the work is a narrative design toolbox for designers and museum professionals, enabling and encouraging the development of new approaches for museum and exhibition design practice.

Sagittarius A* Accretion Flow and Black Hole Parameters from General Relativistic Dynamical and Polarized Radiative Modeling

description: We obtain estimates of Sgr A* accretion flow and black hole parameters by fitting polarized sub-mm observations with spectra computed using three-dimensional (3D) general relativistic (GR) magnetohydrodynamical (MHD) (GRMHD) simulations. Observations are compiled from averages over many epochs from reports in 29 papers for estimating the mean fluxes Fnu, linear polarization (LP) fractions, circular polarization (CP) fractions, and electric vector position angles (EVPAs). GRMHD simulations are computed with dimensionless spins a_*=0,0.5,0.7,0.9,0.98 over a 20,000M time interval. We perform fully self-consistent GR polarized radiative transfer using our new code to explore the effects of spin a_*, inclination angle θ, position angle (PA), accretion rate Mdot, and electron temperature Te (Te is reported for radius 6M). By fitting the mean sub-mm fluxes and LP/CP fractions, we obtain estimates for these model parameters and determine the physical effects that could produce polarization signatures. Our best bet model has a_*=0.5, θ=75deg, PA=115deg, Mdot=4.6*10^{-8}M_Sun/year, and Te=3.1*10^10K at 6M. The sub-mm CP is mainly produced by Faraday conversion as modified by Faraday rotation, and the emission region size at 230GHz is consistent with the VLBI size of 37microas. Across all spins, model parameters are in the ranges θ=42deg-75deg, Mdot=(1.4-7.0)*10^{-8}M_Sun/year, and Te=(3-4)*10^10K. Polarization is found both to help differentiate models and to introduce new observational constraints on the effects of the magnetic field that might not be fit by accretion models so-far considered.

In this context, we also provide the NLO corrections to the correlation function between two flavour-changing tensor currents, which enters the unitarity constraints for the coefficients in the series expansion.

An Analytic Model of Angular Momentum Transport by Gravitational Torques: From Galaxies to Massive Black Holes

description: We present analytic calculations of angular momentum transport and gas inflow in galaxies, from scales of ~kpc to deep in the potential of a central black hole (BH). We compare these analytic calculations to numerical simulations and use them to develop a sub-grid model of BH growth that can be incorporated into semi-analytic models or cosmological simulations. Both analytic calculations and simulations argue that the strongest torque on gas arises when non-axisymmetric perturbations to the stellar gravitational potential produces orbit crossings and shocks in the gas. This is true both at large radii ~0.01-1 kpc, where bar-like modes dominate the non-axisymmetric potential, and at smaller radii <10 pc, where a lopsided/eccentric disk dominates. The traditional orbit crossing criterion is not always adequate to predict the locations of, and inflow due to, shocks in gas+stellar disks with finite sound speeds. We derive a modified criterion that predicts the presence of shocks in stellar dominated systems even absent formal orbit crossing. We then derive analytic expressions for the loss of angular momentum and the resulting gas inflow rates in the presence of such shocks. We test our analytic predictions using hydrodynamic simulations at a range of galactic scales, and show that they successfully predict the mass inflow rates and quasi-steady gas surface densities with small scatter (0.3 dex). We use our analytic results to construct a new estimate of the BH accretion rate given galaxy properties at larger radii. This captures the key scalings in the numerical simulations. Alternate estimates such as the local viscous accretion rate or the spherical Bondi rate fail systematically to reproduce the simulations.

description: We study a driven-dissipative system of atoms in the presence of laser excitation to a Rydberg state and spontaneous emission. The atoms interact via the blockade effect, whereby an atom in the Rydberg state shifts the Rydberg level of neighboring atoms. We use mean-field theory to study how the Rydberg population varies in space. As the laser frequency changes, there is a continuous transition between the uniform and antiferromagnetic phases. The nonequilibrium nature also leads to a novel oscillatory phase and bistability between the uniform and antiferromagnetic phases.

description: We report a hybrid numerical method for the solution of the model H fluctuating hydrodynamic equations for binary mixtures. The momentum conservation equations with Landau-Lifshitz stresses are solved using the fluctuating lattice Boltzmann equation while the order parameter conservation equation with Langevin fluxes are solved using the stochastic method of lines. Two methods, based on finite difference and finite volume, are proposed for spatial discretisation of the order parameter equation. Special care is taken to ensure that the fluctuation-dissipation theorem is maintained at the lattice level in both cases. The methods are benchmarked by comparing static and dynamic correlations and excellent agreement is found between analytical and numerical results. The Galilean invariance of the model is tested and found to be satisfactory. Thermally induced capillary fluctuations of the interface are captured accurately, indicating that the model can be used to study nonlinear fluctuations.

description: Surveys based on the Sunyaev-Zel'dovich (SZ) effect provide a fresh view of the galaxy cluster population, one that is complementary to X-ray surveys. To better understand the relation between these two kinds of survey, we construct an empirical cluster model using scaling relations constrained by current X-ray and SZ data. We apply our model to predict the X-ray properties of the Planck SZ Cluster Catalog (PCC) and compare them to existing X-ray cluster catalogs. We find that Planck should significantly extend the depth of the previous all-sky cluster survey, performed in the early 1990s by the ROSAT satellite, and should be particularly effective at finding hot, massive clusters (T > 6 keV) out to redshift unity. These are rare objects, and our findings suggest that Planck could increase the observational sample at z > 0.6 by an order of magnitude. This would open the way for detailed studies of massive clusters out to these higher redshifts. Specifically, we find that the majority of newly-detected Planck clusters should have X-ray fluxes 10^{-13} ergs/s/cm^2 < f_X[0.5-2 keV] < 10^{-12} ergs/s/cm^2, i.e., distributed over the decade in flux just below the ROSAT All Sky Survey limit. This is sufficiently bright for extensive X-ray follow-up campaigns. Once Planck finds these objects, XMM-Newton and \textit{Chandra} could measure temperatures to 10% for a sample of ~ 100 clusters in the range 0.5 < z < 1, a valuable increase in the number of massive clusters studied over this range.

description: We investigate steady states of a quasilinear first order hyperbolic partial integro-differential equation. The model describes the evolution of a hierarchical structured population with distributed states at birth. Hierarchical size-structured models describe the dynamics of populations when individuals experience size-specific environment. This is the case for example in a population where individuals exhibit cannibalistic behavior and the chance to become prey (or to attack) depends on the individual's size. The other distinctive feature of the model is that individuals are recruited into the population at arbitrary size. This amounts to an infinite rank integral operator describing the recruitment process. First we establish conditions for the existence of a positive steady state of the model. Our method uses a fixed point result of nonlinear maps in conical shells of Banach spaces. Then we study stability properties of steady states for the special case of a separable growth rate using results from the theory of positive operators on Banach lattices.

description: To increase the utility of Gene Ontology annotations for interpretation of genome-wide experimental data, we have developed GO-CAM, a structured framework for linking multiple GO annotations into an integrated model of a biological system. We expect that GO-CAM will enable new applications in pathway and network analysis as well as improving standard GO annotations for traditional GO-based applications.

Touching the air of paradise lost : an investigation into air's instability
Creators: name: Choi, Mari
Publisher: name: University of British Columbia
Year: 2022

description: This paper traces how Milton characterizes the physically unphysical air of its world in two ways: put simply, physically and absurdly. It will serve as an interesting gateway to understanding the vitality of the very things that surround and incarcerate us. In an epic deeply rooted in the dichotomy between good and evil, how does the natural fit into such conflicts and distinctions? Is nature exploitable, or perhaps the only truly neutral force in a world where no one or thing else can be neutral? In the climate of Renaissance exploration and curiosity, Milton’s portrayal of the natural, agential world is particularly interesting. His treatment of air transcends the limiting bounds of tendency, typicality, and topicality; for Milton, air is a multifunctioning, multidimensional, tangible and yet wispy enigma. I will use that as a starting point to explore air as a force in the world of Paradise Lost, to examine the ways in which Milton uses and differs from Renaissance attitudes and understandings of air. His use of the concept of air in Paradise Lost is complex; it is clear that he is engaging with certain scientific ideas about air as a gas, but there is a tendency to give air unexpected properties of physicality, gender and power. This tension between standard ideas and unique modifications is what makes examining Milton’s usage of air such an interesting pursuit. While he was not the only seventeenth-century poet concerned with materiality, and more broadly vitality, his take is made unique by his abstract experimentation with and insistence for the multifaceted nature of nature: his treatment of nature far exceeds that of greenery and transcends the bounds of personification as it engages with metaphysical contemplations about an air that is both essential to life and has the ability to produce divine judgments, change colour, shape and size, act as a physical conduit for chemical and magical reactions, and be literally substantiated in the physical world.
Novel Biomarkers for Heart Failure: A Proteomic Approach

description: Heart failure (HF) is clinical syndrome growing in economic burden worldwide as it is difficult to diagnose due to its multiple aetiologies and comorbidities, it is expensive to treat and has poor patient outcomes. Even with improvements in therapy and diagnostic methods, heart failure still affects over 500, 000 individuals in the UK alone. The main aim of this project was to identify novel protein biomarkers that predict HF prognosis in heart failure patients that have received optimal therapy for one year. Extracellular vesicle (ECV) and Calcium Silicate Matrix (CSM) enrichment methods were employed to isolate low and mid abundance proteins in these patient samples. Parallel Reaction Monitoring (PRM) with heavy labelling and Selected Reaction Monitoring (SRM) with surrogate peptides were then used to detect and semi-quantitate these proteins using peptides unique to each protein. This is the first time, to our knowledge that PRM with heavy labelling or SRM with surrogate peptides have been used for the identification and relative quantification of peptides for the discovery of biomarkers in HF samples. Limma analysis of proteins detected using SRM with surrogate peptides identified seven peptides (representing seven proteins) that were differentially expressed between the patient samples observed in this study (FDR < 0.05). Five of these proteins were differentially expressed in both discovery work using data independent acquisition and targeted work using SRM in this project. These five proteins are the final panel of potential biomarkers identified in this project and are candidate biomarkers for heart failure: Apolipoprotein M, Apolipoprotein C-III, Fermitin family homolog 3, Antithrombin-III and Vitronectin. To establish these five proteins as true predictors of prognosis in heart failure patients, future work is required such as absolute quantification of these five proteins using stable isotope labels.

Anomalously large capacitance of a plane capacitor with a two-dimensional electron gas

description: In electronic devices where a two-dimensional electron gas (2DEG) comprises one or both sides of a plane capacitor, the resulting capacitance $C$ can be larger than the "geometric capacitance" $C_g$ determined by the physical separation $d$ between electrodes. This larger capacitance is known to result from the Coulomb correlations between individual electrons within the low density 2DEG, which lead to a negative thermodynamic density of states (negative compressibility). Experiments on such systems generally operate in the regime where the average spacing between electrons $n^{-1/2}$ in the 2DEG is smaller than $d$, and these experiments observe $C > C_g$ by only a few percent. A recent experiment [1], however, has observed $C$ larger than $C_g$ by almost 40% while operating in the regime $nd^2 << 1$. In this paper we argue that at $nd^2 << 1$ correlations between the electronic charge of opposite electrodes become important. We develop a theory of the capacitance for the full range of $nd^2$. We show that, in the absence of disorder, the capacitance can be $4d/a$ times larger than the geometric value, where $a << d$ is the electron Bohr radius. Our results compare favorably with the experiment of Ref. [1] without the use of adjustable parameters.
