description: We construct SU($N$) toric code model describing the dynamics of SU($N$) electric and magnetic fluxes on a two dimensional torus. We show that the model has $N^2$ topologically distinct ground states $|ψ_0\rangle_{({\mathsf p},{\mathsf q})}$ which are loop states characterized by $Z_N \otimes Z_N$ centre charges $({\mathsf p},{\mathsf q} =0,1,2,\cdots, N-1)$. We explicitly construct them in terms of coherent superpositions of all possible spin network states on torus with Wigner coefficients as their amplitudes. All excited quasiparticle states with SU($N$) electric charges and magnetic fluxes are constructed. We show that the braiding statistics of these SU(N) electric, magnetic quasiparticles or nonabelian anyons is encoded in the Wigner rotation matrices.

description: Charge carriers in graphene are chiral quasiparticles ("massless Dirac fermions"). Graphene provides therefore an amazing opportunity to study subtle quantum relativistic effects in condensed matter experiment. Here I review a theory of one of these unusual features of graphene, a "pseudodiffusive" transport in the limit of zero charge carrier concentration, which is related to existence of zero-modes of the Dirac operator and to the Zitterbewegung of unltrarelativistic particles. A conformal mapping technique is a powerful mathematical tool to study these phenomena, as demonstrated here, using the Aharonov-Bohm effect in graphene rings with Corbino geometry as an example.

description: We study the Riesz $(a,p)$-capacity of the so called Dobiński set. We characterize the values of the parameters $a$ and $p$ for which the $(a,p)$-Riesz capacity of the Dobiński set is positive. In particular we show that the Dobiński set has positive logarithmic capacity, thus answering a question of Dayan, Fernandéz and González. We approach the problem by considering the dyadic analogues of the Riesz $(a,p)$-capacities which seem to be better adapted to the problem.

description: The similarity of the visible and dark matter abundances indicates that they may originate via the same mechanism. If both the dark and the visible matter are charged under a generalized baryon number which remains always conserved, then the asymmetry of the visible sector may be compensated by an asymmetry in the dark sector. We show how the separation of baryonic and antibaryonic charge can originate in the vacuum, via the Affleck-Dine mechanism, due to the breaking of a symmetry orthogonal to the baryon number. Symmetry restoration in the current epoch guarantees the individual stability of the two sectors.

Imposing harmony in East Asia : a comparative study of the Early Modern community compact system in Chosŏn Korea and Ming China
Creators: name: Khalaf, Ali
Publisher: name: University of British Columbia
Year: 2020

description: This much needed study on Chosŏn Korea (1392-1897) and Ming China (1368-1644) aims to realize two objectives. First, it provides a general understanding of the community compact organizations in both Early Modern East Asian states around the 16th-17th centuries. For this purpose, a coherent structure is adopted where the explanation of the development of community compacts in each region is followed by a review of the different aspects related to this institution. These various elements of the community compacts are categorized into four facets; administrative, judicial, welfare, and the instillation of morals. These four facets also serve as a comparative framework for the second, and principal, objective that is that of a comparative study of the community compact system between Ming China and Chosŏn Korea, meaning an examination of the similarities and differences between both states. To obtain the most representative sample for this research, what we understand to be the most influential compact models in both societies are used for comparison. By doing so, this work reaches a number of conclusions pertaining to the particularities of Ming and Chosŏn social, political and cultural realities which are reflected in the organization and the content of their respective community compact models and examples. Generally speaking, this will permit us to see that the Ming government had a more hands-on approach concerning the management of its localities while Chosŏn’s socio-political system implied, in effect, a higher degree of shared authority with its local elites.
Resonant Leptogenesis in the Minimal B-L Extended Standard Model at TeV

description: We investigate the resonant leptogenesis scenario in the minimal B-L extended standard model(SM) with the B-L symmetry breaking at the TeV scale. Through detailed analysis of the Boltzmann equations, we show how much the resultant baryon asymmetry via leptogenesis is enhanced or suppressed, depending on the model parameters, in particular, the neutrino Dirac Yukawa couplings and the TeV-scale Majorana masses of heavy degenerate neutrinos. In order to consider a realistic case, we impose a simple ansatz for the model parameters and analyze the neutrino oscillation parameters and the baryon asymmetry via leptogenesis as a function of only a single CP-phase. We find that for a fixed CP-phase all neutrino oscillation data and the observed baryon asymmetry of the present universe can be simultaneously reproduced.

Probing cosmic strings by reconstructing polarization rotation of the cosmic microwave background

description: Cosmic birefringence -- the rotation of the polarization of the cosmic microwave background (CMB) photons as they travel to the Earth -- is a smoking gun for axion-like particles (ALPs) that interact with the photon. It has recently been suggested that topological defects in the ALP field called cosmic strings can cause polarization rotation in quantized amounts that are proportional to the electromagnetic chiral anomaly coefficient $\mathcal A$, which holds direct information about physics at very high energies. In this work, we study the detectability of a random network of cosmic strings through estimating rotation using quadratic estimators (QEs). We show that the QE derived from the maximum likelihood estimator is equivalent to the recently proposed global-minimum-variance QE; the classic Hu-Okamoto QE equals the global-minimum-variance QE under special conditions, but is otherwise still nearly globally optimal. We calculate the sensitivity of QEs to cosmic birefringence from string networks, for the Planck satellite mission, as well as for third- and fourth-generation ground-based CMB experiments. Using published binned rotation power spectrum derived from the Planck 2015 polarization data, we obtain a constraint $\mathcal A^2\,ξ_0 < 0.93$ at the 95\% confidence level, where $ξ_0$ is the total length of strings in units of the Hubble scale per Hubble volume, for a phenomenological but reasonable string network model describing a continuous distribution of string sizes. Looking forward, experiments such as the Simons Observatory and CMB-S4 will either discover or falsify the existence of an ALP string network for the theoretically plausible parameter space $\mathcal A^2\,ξ_0 \gtrsim 0.01$.
Evolution of non-thermal emission from shell associated with AGN jets

description: We explore the evolution of the emissions by accelerated electrons in shocked shells driven by jets in active galactic nuclei (AGNs). Focusing on powerful sources which host luminous quasars, we evaluated the broadband emission spectra by properly taking into account adiabatic and radiative cooling effects on the electron distribution. The synchrotron radiation and inverse Compton (IC) scattering of various photons that are mainly produced in the accretion disc and dusty torus are considered as radiation processes. We show that the resultant radiation is dominated by the IC emission for compact sources (< 10kpc), whereas the synchrotron radiation is more important for larger sources. We also compare the shell emissions with those expected from the lobe under the assumption that a fractions of the energy deposited in the shell and lobe carried by the non-thermal electrons are $ε_e \sim 0.01$ and $ε_{e, lobe} \sim 1$, respectively. Then, we find that the shell emissions are brighter than the lobe ones at infra-red and optical bands when the source size is > 10kpc, and the IC emissions from the shell at > 10 GeV can be observed with the absence of contamination from the lobe irrespective of the source size. In particular, it is predicted that, for most powerful nearby sources ($L_j \sim 10^{47} ergs s^{-1}$), TeV gamma-rays produced via the IC emissions can be detected by the modern Cherenkov telescopes such as MAGIC, HESS and VERITAS.

Quadrature Squeezing And Temperature Estimation From The Fock Distribution

description: We present a method to estimate the amount of squeezing and temperature of a single-mode Gaussian harmonic oscillator state based on the weighted least squares estimator applied to measured Fock state populations. Squeezing and temperature, or equivalently the quadrature variances, are essential parameters states used in various quantum communication and sensing protocols. They are often measured with homodyne-style detection, which requires a phase reference such as a local oscillator. Our method allows estimation without a phase reference, by using for example a photon-number-resolving detector. To evaluate the performance of our estimator, we simulated experiments with different values of squeezing and temperature. From 10,000 Fock measurement events we produced estimates for states whose fidelities to the true state are greater than 99.99% for small squeezing (r < 1.0), and for high squeezing (r = 2.5) we obtain fidelities greater than 99.9%. We also report confidence intervals and their coverage probabilities.

Chiral symmetry in the low-energy limit of QCD at finite temperature

description: We derive a non-local Nambu-Jona-Lasinio model from QCD with a form factor exactly obtained in the infrared limit. With this model, having all the parameters properly fixed through those of QCD, we consider the case of finite temperature and compute the solution of the gap equation at small temperature and small momenta and zero chemical potential. Taking the quark masses to be zero, it is proved that the theory undergoes a phase transition with a critical temperature exactly determined. These results prove unequivocally that the picture of the vacuum of QCD as a liquid of instantons is a very good approximation.

description: The University of Maryland Libraries received a National Endowment for the Humanities grant in 2019 to digitize the Dance Exchange collection, a video collection of performances and rehearsals and their corresponding paper programs. The Dance Exchange was founded by Liz Lerman, a well-known choreographer whose ethos of “dance for all” underscores the type of work and community programs created by the company and the performers, including all ages and differently-abled participants. This paper will discuss a brief history of the project and content, why this collection was prioritized by the curator, and the importance to the wider dance community. We will focus this report on the Libraries’ best practice technical standards implemented and expanded for this project and why implementing the metadata was important as we were moving to new digital preservation technologies. The standards include video technical specifications, metadata XML specifications, and embedded metadata specifications. We will also elaborate on how we scaled up workflows built to handle previous projects of a few hundred items to a project of over 1,100 items, and the challenges of reviewing, modifying, and moving the large amount of metadata and data. A major impediment for this project was that the university and our vendor closed due to the pandemic at a key point when we were receiving files back for review. We will examine how we changed digitization and review workflows due to the need to move the project work remotely. A final challenge we are currently experiencing is a massive repository and digital preservation archive migration. We will share how we are working with repository managers and digital preservationists during the university closure to complete the work necessary for getting the content online. We will conclude by discussing how we will implement the changes we made to future av digitization projects.

description: In this paper, we present a method of building strong, explainable classifiers in the form of Boolean search rules. We developed an interactive environment called CASE (Computer Assisted Semantic Exploration) which exploits word co-occurrence to guide human annotators in selection of relevant search terms. The system seamlessly facilitates iterative evaluation and improvement of the classification rules. The process enables the human annotators to leverage the benefits of statistical information while incorporating their expert intuition into the creation of such rules. We evaluate classifiers created with our CASE system on 4 datasets, and compare the results to machine learning methods, including SKOPE rules, Random forest, Support Vector Machine, and fastText classifiers. The results drive the discussion on trade-offs between superior compactness, simplicity, and intuitiveness of the Boolean search rules versus the better performance of state-of-the-art machine learning models for text classification.

Leaf the kids outdoors : approaches and enquiries in quantifying natural environments for health
Creators: name: Davis, Zoë
Publisher: name: University of British Columbia
Year: 2020

description: Over the past few decades there has been an increased interest in how urban natural environments (NEs) affect health, particularly with the migration of people into cities and subsequent densification. Recently, there has been an increase in studies on associations between NEs and childhood health and development, but, to date, no systematic assessment of evidence level exists, especially not within the context of different NE exposure measurements. The focus of this research is to determine which NE measurements have been used in childhood health and development research and to assess if associations and the relative level of evidence changes with different NE metrics. Additionally, this thesis seeks to evaluate possible risk of misclassification of NE exposure due to temporal alignment issues between NE exposure and health data by analyzing general and local vegetation change in Metro Vancouver over a 15-year period. The most common NE metrics identified in the systematic review (Chapter 2) were remote sensing derived metrics, such as the normalized difference vegetation index (NDVI) and land use/land cover datasets. These metrics were also most consistently associated to health outcomes, particularly birth outcomes and decreased ADHD symptoms. Overall, there was considerable heterogeneity within NE metrics, suggesting that more research is needed before conclusions on evidence level can be made. Through modeling NDVI over time with the Theil-Sen estimator, it was found that vegetation remained relatively stable throughout the Metro Vancouver region, an exception being in localized areas of the southeast. Additionally, large amounts of variation were found in NDVI between years, suggesting that direct comparison of NDVI between years is not advisable. To minimize the risk of misclassification in exposure, datasets should be aligned temporally. Ultimately, this thesis discusses and highlights the importance of careful consideration of measurement selection for NE exposure in health studies. While confirming some evidence for childhood health benefits through NE exposure, the thesis concludes that, to date, research has insufficiently considered optimal selection of NE metric and the impact of vegetation change over time. These are important consideration for improving evidence-based decisions for healthy urban planning and should be considered in future studies.

description: In this manuscript we study the counting problem for harmonic trinomials of the form $aζ^n+b\overlineζ^m+c$, where $n,m\in \mathbb{N}$, $n>m$, and $a$, $b$ and $c$ are non-zero complex numbers. As a consequence, we obtain the Fundamental Theorem of Algebra and the Wilmshurst conjecture for harmonic trinomials. The proof of the counting problem relies on the Bohl method introduced in Bohl (1908).

description: Interference of fractionally charged quasi-particles is expected to lead to Aharonov-Bohm oscillations with periods larger than the flux quantum. However, according to the Byers-Yang theorem, observables of an electronic system are invariant under an adiabatic insertion of a quantum of singular flux. We resolve this seeming paradox by considering a microscopic model of electronic interferometers made from a quantum Hall liquid at filling factor 1/m. An approximate ground state of such interferometers is described by a Laughlin type wave function, and low-energy excitations are incompressible deformations of this state. We construct a low-energy effective theory by restricting the microscopic Hamiltonian of electrons to the space of incompressible deformations and show that the theory of the quantum Hall edge so obtained is a generalization of a chiral conformal field theory. In our theory, a quasi-particle tunneling operator is found to be a single-valued function of tunneling point coordinates, and its phase depends on the topology determined by the positions of Ohmic contacts. We describe strong coupling of the edge states to Ohmic contacts and the resulting quasi-particle current through the interferometer with the help of a master equation. We find that the coherent contribution to the average quasi-particle current through Mach-Zehnder interferometers does not vanish after summation over quasi-particle degrees of freedom. However, it acquires oscillations with the electronic period, in agreement with the Byers-Yang theorem. Importantly, our theory does not rely on any ad-hoc constructions, such as Klein factors, etc. When the magnetic flux through an FP interferometer is varied with a modulation gate, current oscillations have the quasi-particle periodicity, thus allowing for spectroscopy of quantum Hall edge states.

description: Ever since the 1997 Asian financial crisis, the nations of East Asia have found a renewed political focus: regional economic cooperation. It has been close to ten years since the financial catastrophe, and it has brought tremendous change, not just for certain countries, but for the region as a whole. The distrust of foreign capital, although still prevalent, has diminished. Certain markets were opened up through vigorous restructuring, consolidation, and then through expansion. As elsewhere in the world, growth in the information technology (IT) sector helped boost many economies, while the emergence of China as the region's economic engine has, and will stay, at the forefront of everyone's mind for years to come. Although economic growth in East Asia has recently been robust, it shows signs of slowing down due to cyclical issues, higher oil prices, and other factors. There are still many issues East Asia needs to tackle, including the elimination of deep political mistrust toward one another, the ongoing need for an even more stable financial market, and a continuation of government and institutional assistance when a crisis similar to the one in 1997 happens again. How should the region proceed hereon? What kind of roadmap should East Asia follow in order to strengthen its financial and monetary cooperation and integration? To answer some of these questions, on September 12, 2005, the Center on Japanese Economy and Business invited Mr. Haruhiko Kuroda, President of the Asian Development Bank to Columbia Business School, to outline some of his thoughts and suggestions on regional economic cooperation. This program was co-sponsored by the APEC Study Center of Columbia University.

description: Objectives: No randomised controlled trials have been conducted for breakthrough pain in paediatric palliative care and there are currently no standardised outcome measures. The DIPPER study aims to establish the feasibility of conducting a prospective randomised controlled trial comparing oral and transmucosal administration of opioids for breakthrough pain. The aim of the current study was to achieve consensus on design aspects for a small-scale prospective study to inform a future randomised controlled trial of oral morphine, the current first-line treatment, versus transmucosal diamorphine. Methods: The nominal group technique was used to achieve consensus on best practice for mode of administration, dose regimen and a range of suitable pain intensity outcome measures for transmucosal diamorphine in children and young people with breakthrough pain. An expert panel of ten clinicians in paediatric palliative care and three parent representatives participated. Consensus was achieved when agreement was reached and no further comments from participants were forthcoming. Results: The panel favoured the buccal route of administration, with dosing according to the recommendations in the Association for Paediatric Palliative Medicine formulary (fifth Edition, 2020). The verbal Numerical Rating Scale was selected to measure pain in children 8 years old and older, the Faces Pain Scale-Revised for children between 4 and 8 years old, and Face, Legs, Activity, Cry and Consolability (FLACC)/FLACC-Revised as the observational tools. Conclusions: The nominal group technique allowed consensus to be reached for a small-scale, prospective, cohort study and provided information to inform the design of a randomised controlled trial.

description: Comparison of data representations is a complex multi-aspect problem that has not enjoyed a complete solution yet. We propose a method for comparing two data representations. We introduce the Representation Topology Divergence (RTD), measuring the dissimilarity in multi-scale topology between two point clouds of equal size with a one-to-one correspondence between points. The data point clouds are allowed to lie in different ambient spaces. The RTD is one of the few TDA-based practical methods applicable to real machine learning datasets. Experiments show that the proposed RTD agrees with the intuitive assessment of data representation similarity and is sensitive to its topological structure. We apply RTD to gain insights on neural networks representations in computer vision and NLP domains for various problems: training dynamics analysis, data distribution shift, transfer learning, ensemble learning, disentanglement assessment.

description: We present an identity for an unbiased estimate of a general statistical distribution. The identity computes the distribution density from dividing a histogram sum over a local window by a correction factor from a mean-force integral, and the mean force can be evaluated as a configuration average. We show that the optimal window size is roughly the inverse of the local mean-force fluctuation. The new identity offers a more robust and precise estimate than a previous one by Adib and Jarzynski [J. Chem. Phys. 122, 014114, (2005)]. It also allows a straightforward generalization to an arbitrary ensemble and a joint distribution of multiple variables. Particularly we derive a mean-force enhanced version of the weighted histogram analysis method (WHAM). The method can be used to improve distributions computed from molecular simulations. We illustrate the use in computing a potential energy distribution, a volume distribution in a constant-pressure ensemble, a radial distribution function and a joint distribution of amino acid backbone dihedral angles.

description: We consider uniformly elliptic operators with Dirichlet or Neumann homogeneous boundary conditions on a domain $Ω$ in ${\mathbb{R}}^N$. We consider deformations $ϕ(Ω)$ of $Ω$ obtained by means of a locally Lipschitz homeomorphism $ϕ$ and we estimate the variation of the eigenfunctions and eigenvalues upon variation of $ϕ$. We prove general stability estimates without using uniform upper bounds for the gradients of the maps $ϕ$. As an application, we obtain estimates on the rate of convergence for eigenvalues and eigenfunctions when a domain with an outward cusp is approximated by a sequence of Lipschitz domains.

description: Extensive calculations on isoscaling behavior with the sequential-decay model gemini are performed for the medium-to-heavy nuclei in the mass range A = 60-120 at excitation energies up to 3 MeV/nucleon. The comparison between the products after the first-step decay and the ones after the entire-steps decay demonstrates that there exists a strong sequential decay effect on the final isoscaling parameters and the apparent temperature. Results show that the apparent symmetry energy coefficient $γ_{app}$ does not reflect the initial symmetry energy coefficient $C_{sym}$ embedded in the mass calculation in the present GEMINI model.

Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2021

description: La crisi sanitaria sociale ed economica innescata dall’emergenza Covid-19 coinvolge le dimensioni della nostra sfera personale: comportamenti e abitudini. L’acquisto di un capo di abbigliamento non è più solo soddisfare un piacere edonistico, ma l’etica dell’acquisto diventa il valore che spinge il consumatore. L’azienda moda deve intercettare il cambiamento ed essere in grado di ripensare al proprio ruolo nel sociale. Il mio progetto di tesi sviluppa ed approfondisce tutti quegli aspetti che contribuiscono alla definizione dell’identità visiva del brand come il logo e la sua applicazione su diversi supporti. Il mio obiettivo è la valorizzazione della dimensione sociale ed etica del brand che vuole distinguersi all’interno del settore moda per i propri valori, in quanto parte del ricavato sarà destinato alle associazioni già operanti sul territorio milanese che offrono assistenza e supporto ai soggetti più fragili. Creare un linguaggio adattabile ai diversi supporti costruendo una comunicazione coerente ed identificabile, ponendo in primo piano i valori sociali prima ancora di quelli tipicamente connessi al contesto e relativi agli aspetti finanziari. L’atto di acquisto si trasforma in valore, coinvolgendo il consumatore in un modello di acquisto responsabile.

description: Objectives: The Oxford–AstraZeneca COVID-19 vaccine (ChAdOx1 nCoV-19, Vaxzevira or Covishield) builds on two decades of research and development (R&D) into chimpanzee adenovirus-vectored vaccine (ChAdOx) technology at the University of Oxford. This study aimed to approximate the funding for the R&D of ChAdOx and the Oxford–AstraZeneca vaccine and to assess the transparency of funding reporting mechanisms. Methods: We conducted a scoping review and publication history analysis of the principal investigators to reconstruct R&D funding the ChAdOx technology. We matched award numbers with publicly accessible grant databases. We filed freedom of information (FOI) requests to the University of Oxford for the disclosure of all grants for ChAdOx R&D. Results: We identified 100 peer-reviewed articles relevant to ChAdOx technology published between January 2002 and October 2020, extracting 577 mentions of funding bodies from acknowledgements. Government funders from overseas (including the European Union) were mentioned 158 times (27.4%), the UK government 147 (25.5%) and charitable funders 138 (23.9%). Grant award numbers were identified for 215 (37.3%) mentions; amounts were publicly available for 121 (21.0%). Based on the FOIs, until December 2019, the biggest funders of ChAdOx R&D were the European Commission (34.0%), Wellcome Trust (20.4%) and Coalition for Epidemic Preparedness Innovations (17.5%). Since January 2020, the UK government contributed 95.5% of funding identified. The total identified R&D funding was £104 226 076 reported in the FOIs and £228 466 771 reconstructed from the literature search. Conclusion: Our study approximates that public and charitable financing accounted for 97%–99% of identifiable funding for the ChAdOx vaccine technology research at the University of Oxford underlying the Oxford–AstraZeneca vaccine until autumn 2020. We encountered a lack of transparency in research funding reporting.
The Price of Transitional Justice: A Cost‐Benefit Analysis of its Mechanisms in Post‐Revolution Phase
Creators: name: Rashwan, Eman M.
Publisher: name: University of Bologna Law Review
Year: 2021

description: Transitional Justice [hereinafter T.J.] in the post-revolution phase refers to the policies that aim to deal with the autocratic past-regime violations against its people to achieve accountability and democracy and promote human rights and the rule of law. To achieve these goals, the United Nations, within its Rule of Law Initiative, issued in 2010, a set of five mechanisms that work as guidelines for nations recovering from conflicts. I argue that whatever the mechanism or combination selected by a society transforming from an autocracy into democracy is, the nature of these mechanisms requires a trade-off between multiple considerations. To explain this inevitable trade-off, I go through each mechanism in detail, analyze it from both legal and economic perspectives, and then provide a basic cost-benefit analysis. I suggest that transitional justice as a constitutional arrangement requires a holistic approach in its adoption and application because this initial cost-benefit analysis cannot be standardized for all cases. I also suggest that transitional justice policies that take into account proportionality, a combination of different mechanisms, customization of the mechanisms upon the relevant case, and adopting these policies in the formality of basic or organic laws may be expected to have the most effective outcomes achieving the goals of T.J. with the least legal complications.
