description: Relativistic causality has dramatic consequences on the measurability of nonlocal variables and poses the fundamental question of whether it is physically meaningful to speak about the value of nonlocal variables at a particular time. Recent work has shown that by weakening the role of the measurement in preparing eigenstates of the variable it is in fact possible to measure all nonlocal observables instantaneously by exploiting entanglement. However, for these measurement schemes to succeed with certainty an infinite amount of entanglement must be distributed initially and all this entanglement is necessarily consumed. In this work we sharpen the characterisation of instantaneous nonlocal measurements by explicitly devising schemes in which only a finite amount of the initially distributed entanglement is ever utilised. This enables us to determine an upper bound to the average consumption for the most general cases of nonlocal measurements. This includes the tasks of state verification, where the measurement verifies if the system is in a given state, and verification measurements of a general set of eigenstates of an observable. Despite its finiteness the growth of entanglement consumption is found to display an extremely unfavourable exponential of an exponential scaling with either the number of qubits needed to contain the Schmidt rank of the target state or total number of qubits in the system for an operator measurement. This scaling is seen to be a consequence of the combination of the generic exponential scaling of unitary decompositions combined with the highly recursive structure of our scheme required to overcome the no-signalling constraint of relativistic causality.

description: Charge density waves (CDWs) underpin the electronic properties of many complex materials. Near-equilibrium CDW order is linearly coupled to a periodic, atomic-structural distortion, and the dynamics is understood in terms of amplitude and phase modes. However, at the shortest timescales lattice and charge order may become de-coupled, highlighting the electronic nature of this many-body broken symmetry ground state. Using time and angle resolved photoemission spectroscopy with sub-30-fs XUV pulses, we have mapped the time- and momentum-dependent electronic structure in photo-stimulated 1T-TaS2, a prototypical two-dimensional charge density wave compound. We find that CDW order, observed as a splitting of the uppermost electronic bands at the Brillouin zone boundary, melts well before relaxation of the underlying structural distortion. Decoupled charge and lattice modulations challenge the view of Fermi Surface nesting as a driving force for charge density wave formation in 1T-TaS2.

Higher order variational origin of the Dixon's system and its relation to the quasi-classical 'Zitterbewegung' in General Relativity

description: We show how the Dixon's system of first order equations of motion for the particle with inner dipole structure together with the side Mathisson constraint follows from rather general construction of the 'Hamilton system' developed by Weyssenhoff, Rund and Grässer to describe the phase space counterpart of the evolution under the ordinary Euler-Poisson differential equation of the parameter-invariant variational problem with second derivatives. One concrete expression of the 'Hamilton function' leads to the General Relativistic form of the fourth order equation of motion known to describe the quasi-classical 'quiver' particle in Special Relativity. The corresponding Lagrange function including velocity and acceleration coincides in the flat space of Special Relativity with the one considered by Bopp in an attempt to give an approximate variational formulation of the motion of self-radiating electron, when expressed in terms of geometric quantities.

description: We clarify the relation between the ergodicity breaking transition predicted by mode-coupling theory and the so-called dynamic transition predicted by the static replica approach. Following Franz and Parisi [Phys. Rev. Lett. 79, 2486 (1997)], we consider a system of particles in a metastable state characterized by non-trivial correlations with a quenched configuration. We show that the assumption that in a metastable state particle currents vanish leads to an expression for the replica off-diagonal direct correlation function in terms of a replica off-diagonal static four-point correlation function. A factorization approximation for this function results in an approximate closure for the replica off-diagonal direct correlation function. The replica off-diagonal Ornstein-Zernicke equation combined with this closure coincides with the equation for the non-ergodicity parameter derived using the mode-coupling theory.

description: We continue our study of the Cauchy problem for the homogeneous (real and complex) Monge-Ampere equation (HRMA/HCMA). In the prequel a quantum mechanical approach for solving the HCMA was developed, and was shown to coincide with the well-known Legendre transform approach in the case of the HRMA. In this article---that uses tools of convex analysis and can be read independently---we prove that the candidate solution produced by these methods ceases to solve the HRMA, even in a weak sense, as soon as it ceases to be differentiable.

description: We show that the category of rational G-spectra for a torus G is Quillen equivalent to an explicit small and practical algebraic model, thereby providing a universal de Rham model for rational G-equivariant cohomology theories. The result builds on the first author's Adams spectral sequence, the second author's functors making rational spectra algebraic. There are several steps, some perhaps of wider interest (1) isotropy separation (replacing the category of G-spectra by modules over a diagram of isotropically simple ring G-spectra) (2) passage to fixed points on ring and module categories (replacing diagrams of ring G-spectra by diagrams of ring spectra) (3) replacing diagrams of ring spectra by diagrams of differential graded algebras (4) rigidity (replacing diagrams of DGAs by diagrams of graded rings). Systematic use of cellularization of model categories is central.

description: We examine the dependence of parton distribution functions (PDFs) on the value of the QCD coupling strength $α_{s}(M_{Z})$. We explain a simple method that is rigorously valid in the quadratic approximation normally applied in PDF fitting, and fully reproduces the correlated dependence of theoretical cross sections on $α_s$ and PDF parameters. This method is based on a statistical relation that allows one to add the uncertainty produced by $α_s$, computed with some special PDF sets, in quadrature with the PDF uncertainty obtained for the fixed $α_s$ value (such as the CTEQ6.6 PDF set). A series of four CTEQ6.6AS PDFs realizing this approach, for $α_s$ values in the interval $0.116 \leq α_{s}(M_{Z}) \leq 0.120$, is presented. Using these PDFs, the combined $α_{s}$ and PDF uncertainty is assessed for theoretical predictions at the Fermilab Tevatron and Large Hadron Collider.

description: The IDEAMAPS Network (https://ideamapsnetwork.org) aims to develop and maintain an Integrated DEprived Area MAPping System that leverages the strengths of the current silo-ed approaches to "slum" area mapping. The network recently launched the development of a data ecosystem, based on the domain of Deprivation Framework (Abascal et al., 2022, that allows the integration and exchange of data to map and characterize urban deprivation. The aim is to develop a scalable and transferable data approach that builds on Earth Observation (EO) data and methods, open Geospatial data, municipal data, and community-based data. The presentation provides and overview of the conceptual development of the IDEAMAPS ecosystem and EO/Geospatial mapping approaches to produce routine and accurate data on deprivation for urban centres in Low-and-Middle Income Countries (LMICs).

description: Introdução: A doença Coronavírus 2019 (COVID-19), causadora do Síndrome Respiratório Agudo Severo 2 (SARS-CoV-2), foi reportada pela primeira vez, em Wuhan (China) e declarada como pandemia em março de 2020. Até à data, são limitadas as informações clínicas, abordagem anestésica e prognóstico das grávidas infetadas. O objetivo deste estudo, foi a caraterização da experiência clínica e segurança das técnicas anestésicas na abordagem à grávida infetada e submetida a técnicas anestésicas/analgésicas para trabalho de parto ou cesariana. Métodos: Foi realizado um estudo retrospetivo incluindo todas as parturientes infetadas admitias no Centro Hospitalar Universitário de São João. Dados sobre o contexto demográfico, epidemiológico, resultados dos estudos laboratoriais e imagem radiológica realizados à admissão foram colhidos. Analisou-se os procedimentos anestésicos/analgésicos realizados, bem como dados relacionados com a cirurgia, puérpera e neonato. Resultados: Incluiu-se neste estudo 15 parturientes infetadas com SARS-CoV-2. Sintomas e características clínicas foram semelhantes às reportadas na população adulta não obstétrica. O parto vaginal e anestesia/analgesia do neuroeixo foi realizada na maioria dos casos, em contraste com os estudos previamente publicados. Das parturientes sob analgesia epidural, a maioria permaneceu com Patient Controlled Epidural Analgesia até ao parto. Apenas em um caso foi necessário anestesia geral e intubação traqueal. Todos os recém-nascidos foram negativos para SARS-CoV-2. Não foram reportados complicações ou eventos críticos maternos ou nos recém-nascidos. Conclusão: Neste estudo, as técnicas regionais para anestesia/analgesia para trabalho de parto foram a primeira linha na abordagem anestésica das parturientes infetadas. A segurança e eficácia destes procedimentos foram verificadas sem complicações maternas ou neonatais.

description: All generalized Hadamard matrices of order 18 over a group of order 3, H(6,3), are enumerated in two different ways: once, as class regular symmetric (6,3)-nets, or symmetric transversal designs on 54 points and 54 blocks with a group of order 3 acting semi-regularly on points and blocks, and secondly, as collections of full weight vectors in quaternary Hermitian self-dual codes of length 18. The second enumeration is based on the classification of Hermitian self-dual [18,9] codes over GF(4), completed in this paper. It is shown that up to monomial equivalence, there are 85 generalized Hadamard matrices H(6,3), and 245 inequivalent Hermitian self-dual codes of length 18 over GF(4).

Welfare maximization for complementary and competing items and their applications : analysis and algorithm using a utility driven model for achieving better social influence
Creators: name: Banerjee, Prithu
Publisher: name: University of British Columbia
Year: 2022

description: Motivated by applications such as viral marketing, the problem of influence maximization (IM) has been extensively studied in the literature. The goal is to select a small number of users to adopt an item such that it results in a large cascade of adoptions by others. Existing works have three key limitations. (1) They do not account for the economic considerations of a user in buying/adopting items. (2) They cannot model the complex interactions between multiple items. (3) For the network owner, maximizing social welfare is important to ensure customer loyalty, which is not addressed in prior work in the IM literature. In this work, we address all three limitations and propose a novel model called Utility driven Independent Cascade (UIC) that combines utility-driven item adoption with influence propagation over networks. We focus on several types of items such as mutually complementary only, competing only, and a mix of the two in the context of the filter bubble problem. We formulate the problem of social welfare maximization under each of these settings. We show that while the objective function is neither submodular nor supermodular, a constant or instance-dependent approximation can still be achieved. With comprehensive experiments on real and synthetic datasets, we demonstrate that our algorithms significantly outperform all baselines on large real social networks.

description: We study the properties of solutions of fully nonlinear, positively homogeneous elliptic equations near boundary points of Lipschitz domains at which the solution may be singular. We show that these equations have two positive solutions in each cone of $\mathbb{R}^n$, and the solutions are unique in an appropriate sense. We introduce a new method for analyzing the behavior of solutions near certain Lipschitz boundary points, which permits us to classify isolated boundary singularities of solutions which are bounded from either above or below. We also obtain a sharp Phragmén-Lindelöf result as well as a principle of positive singularities in certain Lipschitz domains.

description: We follow arguments of Verlinde and Klinkhamer, and construct two models of the microscopic theory of a holographic screen that allow for the thermodynamical derivation of Newton's law, with Newton's constant expressed in terms of a minimal length scale contained in the area spectrum of the microscopic theory. One of the models is loosely related to the quantum structure of surfaces and isolated horizons in loop quantum gravity. Our investigation shows that the conclusions reached by Klinkhamer regarding the new length scale seem to be generic in all their qualitative aspects.

description: We have previously presented a critique of the standard Marshallian theory of the firm, and developed an alternative formulation that better agreed with the results of simulation. An incorrect mathematical fact was used in our previous presentation. This paper deals with correcting the derivation of the Keen equilibrium, and generalising the result to the asymmetric case. As well, we discuss the notion of rationality employed, and how this plays out in a two player version of the game.
Magneto-elastic oscillations and the damping of crustal shear modes in magnetars

description: In a realistic model of magneto-elastic oscillations in magnetars, we find that crustal shear oscillations, often invoked as an explanation of quasi-periodic oscillations (QPOs) seen after giant flares in soft gamma-ray repeaters (SGRs), are damped by resonant absorption on timescales of at most 0.2s, for a lower limit on the dipole magnetic field strength of 5 x 10^13 G. At higher magnetic field strengths (typical in magnetars) the damping timescale is even shorter, as anticipated by earlier toy-models. We have investigated a range of equations of state and masses and if magnetars are dominated by a dipole magnetic field, our findings exclude torsional shear oscillations of the crust from explaining the observed low-frequency QPOs. In contrast, we find that the Alfvén QPO model is a viable explanation of observed QPOs, if the dipole magnetic field strength exceeds a minimum strength of about several times 10^14 G to 10^15 G. Then, Alfvén QPOs are no longer confined to the fluid core, but completely dominate in the crust region and have a maximum amplitude at the surface of the star.

description: Study on human mobility is gaining increasing attention from the research community with its multiple applications to use in mobile networks, particularly for the purpose of message delivery in the Delay Tolerant Networks. To better understand the potential of mobile nodes as message relays, our study investigates the encounter pattern of mobile devices. Specifically, we examine the extensive network traces that reflect mobility of communication devices. We analyze the periodicity in encounter pattern by using power spectral analysis. Strong periodicity was observed among rarely encountering mobile nodes while the periodicity was weaker among frequently encountering nodes. Further, we present a method to search regularly encountering pairs and discuss the findings. To our knowledge, we are the first to analyze the periodicity of encounter pattern with large network traces, which is a critical basis for designing an efficient delivery scheme using mobile nodes.

description: We investigate properties of the odd Khovanov homology, compare and contrast them with those of the original (even) Khovanov homology, and discuss applications of the odd Khovanov homology to other areas of knot theory and low-dimensional topology. We show that it provides an effective upper bound on the Thurston-Bennequin number of Legendrian links and can be used to detect quasi-alternating knots. A potential application to detecting transversely non-simple knots is also mentioned.

What does it mean to teach? : an arts-based existential exploration with pre-service teachers
Creators: name: Verwoord, Roselynn
Publisher: name: University of British Columbia
Year: 2022

description: Teacher education is a “significant site of adult learning” (Butterwick, 2014). It can also be a place where neo-liberal ideas about how children 'come into presence' in the world are perpetuated. Alternatively, it can be a place where an existential view is adopted with very different outcomes for both teacher candidates and the children in their care. In particular, an existential pedagogy values self-worth and takes into account the individuality of learners as opposed to a one-size-fits-all approach. Using Gert Biesta’s conceptualization of teaching as existential, this study explored pre-service teachers’ beliefs about what it means to teach and pursued the following questions: 1) What are pre-service teachers’ understandings of what it means to be a teacher and to teach? 2) How are explorations of existential questions facilitated by an arts-based approach and an art exchange? 3) What possibilities might existentialism offer to pre-service teachers and teacher education programs? The analysis suggests ways in which existentialism might be enacted to the benefit of teacher candidates, teacher education, and the children within our schools. Outcomes of the study include: the importance of exploring and interrogating one’s understandings of what it means to be a teacher and to teach; the potential of existentialism to create space within teacher education for better understanding the individuality of every person; and the possibilities presented by allowing children to bring their ‘newness into the world.’

description: It is shown that a magnetic field dramatically affects the problem of supercritical charge in graphene making any charge in gapless theory supercritical. The cases of radially symmetric potential well and Coulomb center in an homogeneous magnetic field are considered. The local density of states and polarization charge density are calculated in the first order of perturbation theory. It is argued that the magnetically induced instability of the supercritical Coulomb center can be considered as a quantum mechanical counterpart of the magnetic catalysis phenomenon in graphene.

description: We calculate (q-deformed) Clebsch-Gordan and 6j-coefficients for rank two quantum groups. We explain in detail how such calculations are done, which should allow the reader to perform similar calculations in other cases. Moreover, we tabulate the q-Clebsch-Gordan and 6j-coefficients explicitly, as well as some other topological data associated with theories corresponding to rank-two quantum groups. Finally, we collect some useful properties of the fusion rules of particular conformal field theories.

description: Radiation reaction effects in the interaction of an electron and a strong laser field are investigated in the realm of quantum electrodynamics. We identify quantum radiation reaction with the multiple photon recoils experienced by the laser-driven electron due to consecutive incoherent photon emissions. After determining a quantum radiation dominated regime, we demonstrate how in this regime quantum signatures of radiation reaction strongly affect multiphoton Compton scattering spectra and that they could be measurable in principle with presently available laser technology.

description: We introduce a formalism for handling general spaces of hierarchical tilings, a category that includes substitution tilings, Bratteli-Vershik systems, S-adic transformations, and multi-dimensional cut-and-stack transformations. We explore ergodic, spectral and topological properties of these spaces. We show that familiar properties of substitution tilings carry over under appropriate assumptions, and give counter-examples where these assumptions are not met. For instance, we exhibit a minimal tiling space that is not uniquely ergodic, with one ergodic measure having pure point spectrum and another ergodic measure having mixed spectrum. We also exhibit a 2-dimensional tiling space that has pure point measure-theoretic spectrum but is topologically weakly mixing.

China goes global : a history of Xinhua News Agency’s international expansion from 1978 to 1989
Creators: name: Ren, Elizabeth Wu
Publisher: name: University of British Columbia
Year: 2022

description: This thesis examines how the Communist Party of China (CCP) aimed to establish global media networks through Xinhua News Agency from 1978 to 1989. As China’s central news agency and the highest level of Party-state media, Xinhua was uniquely positioned as the CCP’s mouthpiece and intersection between national media, foreign affairs, and global news. This work focuses on Xinhua’s shift from expanding into the Global South, specifically in Southeast Asia and Central-West Africa, to exploring partnerships with industrialized nations like South Korea. This shift was due to Xinhua’s strategic division of the ‘globe’ into regions that supported its goals to become a world news agency and fulfill the CCP’s political objectives. Xinhua’s globalization came at the heels of the CCP’s reinstitution of “reform and opening” in 1978. This not only re-introduced policies of economic modernization and international re-engagement, but also a new conceptualization of the ‘news’ and news agencies in geopolitical affairs. Namely, Xinhua played a crucial role in this period as the news agency’s disaggregation of the Global South actively worked to achieve its ambitions to transform from a state-run national news agency to a world news agency. This thesis provides a more nuanced understanding into how China saw and defined the region of the “Global South” and contributes to the existing scholarship on South-South connections and China’s own globalization. By situating the CCP’s transformation of Xinhua within this global frame, it shows how Xinhua’s development was not achieved within a historical vacuum. Instead, this research not only demonstrates how the CCP’s goals from 1978 to 1989 are still relevant today, but also enables future scholarship to address broader considerations into how media serves different interest groups within world history and contemporary politics.

description: We investigate the stability of a new warped black string with nontrivial topologies in five-dimensional Anti-de Sitter spacetime. After studying the linear gravitational perturbation, we find that this black string is unstable when the Kaluza-Klein mass falls in a certain range and the instability exists for all topological spacetimes.
