description: Adopting the pullback approach to global Finsler geometry, the aim of the present paper is to provide new intrinsic (coordinate-free) proofs of intrinsic versions of the existence and uniqueness theorems for the Cartan and Berwald connections on a Finsler manifold. To accomplish this, the notions of semispray and nonlinear connection associated with a given regular connection, in the pullback bundle, is introduced and investigated. Moreover, it is shown that for the Cartan and Berwald connections, the associated semispray coincides with the canonical spray and the associated nonlinear connection coincides with the Barthel connection. An explicit intrinsic expression relating both connections is deduced.

On the Kaehler rank of compact complex surfaces
Creators: name: Toma, Matei
Publisher: name: arXiv
Year: 2007
Subjects: subject: Complex Variables (math.CV)
subject: FOS: Mathematics
subject: 32J15, 32H50

description: Harvey and Lawson introduced the Kaehler rank and computed it in connection to the cone of positive exact currents of bidimension (1,1) for many classes of compact complex surfaces. In this paper we extend these computations to the only further known class of surfaces not considered by them, that of Kato surfaces. Our main tool is the reduction to the dynamics of associated holomorphic contractions.
Phase Field Crystals as a Coarse-Graining in Time of Molecular Dynamics
Creators: name: Tupper, P. F.

Publisher: name: arXiv
Year: 2007
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Phase field crystals (PFC) are a tool for simulating materials at the atomic level. They combine the small length-scale resolution of molecular dynamics (MD) with the ability to simulate dynamics on mesoscopic time scales. We show how PFC can be interpreted as the result of applying coarse-graining in time to the microscopic density field of molecular dynamics simulations. We take the form of the free energy for the phase field from the classical density functional theory of inhomogeneous liquids and then choose coefficients to match the structure factor of the time coarse-grained microscopic density field. As an example, we show how to construct a PFC free energy for Weber and Stillinger's two-dimensional square crystal potential which models a system of proteins suspended in a membrane.

Statistical properties of giant pulses from the Crab pulsar

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We have studied the statistics of giant pulses from the Crab pulsar for the first time with particular reference to their widths. We have analyzed data collected during 3.5 hours of observations conducted with the Westerbork Synthesis Radio Telescope operated in a tied-array mode at a frequency of 1200 MHz. The PuMa pulsar backend provided voltage recording of X and Y linear polarization states in two conjugate 10 MHz bands. We restricted the time resolution to 4 microseconds to match the scattering on the interstellar inhomogeneities. In total about 18000 giant pulses (GP) were detected in full intensity with a threshold level of 6 sigma. Cumulative probability distributions (CPD) of giant pulse energies were analyzed for groups of GPs with different effective widths in the range 4 to 65 microseconds. The CPDs were found to manifest notable differences for the different GP width groups. The slope of a power-law fit to the high-energy portion of the CPDs evolves from -1.7 to -3.2 when going from the shortest to the longest GPs. There are breaks in the CPD power-law fits indicating flattening at low energies with indices varying from -1.0 to -1.9 for the short and long GPs respectively. The GPs with a stronger peak flux density were found to be of shorter duration. We compare our results with previously published data and discuss the importance of these peculiarities in the statistical properties of GPs for the heoretical understanding of the emission mechanism responsible for GP generation.

description: A stiff matter-dominated universe modeled by a free massless scalar field minimally coupled to gravity in a Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) geometry is quantized. Generalized complex-width gaussian superpositions of the solutions of the Wheeler-DeWitt equation are constructed and the Bohm-de Broglie interpretation of quantum cosmology is applied. A planar dynamical system is found in which a diversity of quantum bohmian trajectories are obtained and discussed. One class of solutions represents non-singular inflationary models starting at infinity past from flat space-time with Planckian size spacelike hypersurfaces, which inflates without inflaton but due to a quantum cosmological effect, until it makes an analytical graceful exit from this inflationary epoch to a decelerated classical stiff matter expansion phase.

description: In frame of a phenomenological approach based on Compton-like Feynman amplitudes, we study multi-pion production in antiproton nucleon collisions. The main interest of this reaction is related to the possibility to study the properties of the presumable $\bar N N$ atom and of its resonances. For the case of formation of a scalar or pseudoscalar resonant state, with $I^G(J^{P})=1^-(0^{\pm}),~0^+(0^-)$ numerical results are obtained. The differential cross section in an experimental set-up where the pions invariant mass is measured, is given with explicit dependence on the lepton pair and pions invariant mass.

Abelian gauge theories on compact manifolds and the Gribov ambiguity

Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study the quantization of abelian gauge theories of principal torus bundles over compact manifolds with and without boundary. It is shown that these gauge theories suffer from a Gribov ambiguity originating in the non-triviality of the bundle of connections whose geometrical structure will be analyzed in detail. Motivated by the stochastic quantization approach we propose a modified functional integral measure on the space of connections that takes the Gribov problem into account. This functional integral measure is used to calculate the partition function, the Greens functions and the field strength correlating functions in any dimension using the fact that the space of inequivalent connections itself admits the structure of a bundle over a finite dimensional torus. The Greens functions are shown to be affected by the non-trivial topology, giving rise to non-vanishing vacuum expectation values for the gauge fields.

Evaluation of the Axial Vector Commutator Sum Rule for Pion-Pion Scattering

description: We consider the sum rule proposed by one of us (SLA), obtained by taking the expectation value of an axial vector commutator in a state with one pion. The sum rule relates the pion decay constant to integrals of pion-pion cross sections, with one pion off the mass shell. We remark that recent data on pion-pion scattering allow a precise evaluation of the sum rule. We also discuss the related Adler--Weisberger sum rule (obtained by taking the expectation value of the same commutator in a state with one nucleon), especially in connection with the problem of extrapolation of the pion momentum off its mass shell. We find, with current data, that both the pion-pion and pion-nucleon sum rules are satisfied to better than six percent, and we give detailed estimates of the experimental and extrapolation errors in the closure discrepancies.

description: This paper investigates the patterns of saccadic eye movement when using Microsoft's Skype Translator between Catalan and German. As being part of an overall evaluation of the Skype Translator on a dialogue-oriented level, a case study on 21 German-speaking participants was conducted. Despite not having any proficiency in Catalan, these participants had to text-chat with Catalan native speakers via Skype, while the Skype Translator was activated. The sessions were observed by an eye tracking system. The collected data thus represents a naturalistic starting point to evaluate how users structure computer-mediated communication situations when real-time machine translation is involved while having to rely on that output.
Applied science in the curriculum : The case of industrial science 12 in British Columbia
Creators: name: Mackenzie, William Colin
Publisher: name: University of British Columbia
Year: 2010

description: This study investigates the disjunction between macro-level policy decisions concerning the curriculum and the lived experience in the schools resulting from those decisions. The specific case of Industrial Science 12 - a senior secondary applied science introduced in British Columbia in 1965 - is examined in some detail as an instance of this disjunction. Data for this study were gathered through archival searches and personal interviews. The archives of the former British Columbia Shop Teachers' Association and the personal papers of Professor Harry Cannon were the main sources of printed data. Personal interviews were conducted with members of the Course Development Committee, former Department of Education officials, School Board Supervisors, Shop Teachers' Association excecutive members, and teachers of the course. The British Columbia educational milieu of that time is examined, including the effects of international curriculum development projects, the Royal Commission on Education (1960), and the Technical and Vocational Training Assistance Act (1961). The deliberations of the Department of Education and, more particularly, the Course Development Committee, are scrutinized. The reaction of the British Columbia Shop Teachers' Association to the course is analyzed. The brief existence of Industrial Science 12 in the schools of British Columbia is described. Finally, conclusions are advanced to explain the difficulties the course encountered, and implications for future curriculum development in this area are discussed.
Between audiovisual translation and localization: The case of "Detroit: Become Human"
Creators: name: Mejías-Climent, Laura
Publisher: name: Zenodo
Year: 2021

description: The concept of audiovisual translation (AVT) is changing continuously in the current technological landscape, in which localization has emerged as a key process to adapt different types of modern multimedia products. Whether AVT encompasses localization, or vice versa, or they can be conceived as different fields instead, re-
 mains unclear. It is not my intention to find a unique solution to this unanswered question, but rather to shed some light on the convergences of AVT and localization from the specific perspective of dubbing, in a product that, in turn, raises some questions about the genre it belongs to: the graphic adventure Detroit: Become Human
 (Quantic Dream, 2018). This chapter aims to highlight some of the differences and convergences between AVT and localization analyzing the dubbing synchronies applied in a video game belonging to a genre closer to traditional movies, compared to other adventure games, due to the strong presence of cinematic scenes and the lower level of interaction. The results will indicate that, even though clear differences can be found between the localization of a game and translation of non-interactive products, the convergences in terms of dubbing synchronies, particularly in the cinematographic scenes, are quite evident.

description: Interacting quantum systems in the chaotic domain are at the core of various ongoing studies of many-body physics, ranging from the scrambling of quantum information to the onset of thermalization. We propose a minimum model for chaos that can be experimentally realized with cold atoms trapped in one-dimensional multi-well potentials. We explore the emergence of chaos as the number of particles is increased, starting with as few as two, and as the number of wells is increased, ranging from a double well to a multi-well Kronig-Penney-like system. In this way, we illuminate the narrow boundary between integrability and chaos in a highly tunable few-body system. We show that the competition between the particle interactions and the periodic structure of the confining potential reveals subtle indications of quantum chaos for 3 particles, while for 4 particles stronger signatures are seen. The analysis is performed for bosonic particles and could also be extended to distinguishable fermions.

Analysing the dimension of mode in translation
Creators: name: Lapshinova-Koltunski, Ekaterina
Publisher: name: Zenodo
Year: 2021

description: The present chapter applies text classification to test how well we can distinguish between texts along two dimensions: a text-production dimension that distinguishes between translations and non-translations (where translations also include interpreted texts); and a mode dimension that distinguishes between and spoken and written texts. The chapter also aims to investigate the relationship between these two dimensions. Moreover, it investigates whether the same linguistic features that are derived from variational linguistics contribute to the prediction of mode in both translations and non-translations. The distributional information about these features was used to statistically model variation along the two dimensions. The results show that the same feature set can be used to automatically differentiate translations from non-translations, as well as spoken texts from the written texts. However, language variation along the dimension of mode is stronger than that along the dimension of text production, as classification into spoken and written texts delivers better results. Besides, linguistic features that contribute to the distinction between spoken and written mode are similar in both translated and non-translated language.

What can Euclidean distance do for translation evaluations?
Creators: name: Éric André Poirier
Publisher: name: Zenodo
Year: 2021

description: We describe an empirical method to screen informational translation shifts in parallel segment pairs extracted from a bilingual or multilingual translation corpus using two linguistic features that are independent of the languages matched by the translation. The method applies to most known languages and in one or the other of the two translation directions (direct or inverse). The features measured for each segment in source and target languages are character count and lexical word count (or information volume). Information volume is compiled through an algorithm coded in Python using spaCy v2.1.3 core linguistic models. The values of source and target segment features and the translation precision ratio of each segment pairs are averaged over the text to which they belong and all segment values are standardized in relation to their textual average. The deviation between standardized values for each segment in a pair, as measured by the weighted Euclidean distance, allows for the screening and identification of target segments that are atypical or heteromorphic in comparison with their source segment. Our hypothesis is that those heteromorphic segment pairs, as opposed to isomorphic ones, are more likely to contain informational translation shifts. The objective and reproducible method described herein allows for semi-automatic identification of problematic translations and uncovering of textual and linguistic facts revealing translation processes, contingencies, and determinism.

description: Estimating an optimal individualized treatment rule (ITR) based on patients' information is an important problem in precision medicine. An optimal ITR is a decision function that optimizes patients' expected clinical outcomes. Many existing methods in the literature are designed for binary treatment settings with the interest of a continuous outcome. Much less work has been done on estimating optimal ITRs in multiple treatment settings with good interpretations. In this paper, we propose angle-based direct learning (AD-learning) to efficiently estimate optimal ITRs with multiple treatments. Our proposed method can be applied to various types of outcomes, such as continuous, survival or binary outcomes. Moreover, it has an interesting geometric interpretation on the effect of different treatments for each individual patient, which can help doctors and patients make better decisions. Finite sample error bounds have been established to provide a theoretical guarantee for AD-learning. Finally, we demonstrate the superior performance of our method via an extensive simulation study and real data applications.

description: The radio sky at frequencies below $\sim10$ MHz is still largely unknown, this remains the last unexplored part of the electromagnetic spectrum in astronomy. The upcoming space experiments aiming at such low frequencies (ultra-long wavelength or ultra-low frequency) would benefit from reasonable expectations of the sky brightness distribution at relevant frequencies. In this work, we develop a radio sky model that is valid down to $\sim1$ MHz. In addition to the discrete HII objects, we take into account the free-free absorption by thermal electrons in the Milky Way's warm ionized medium (WIM). This absorption effect becomes obvious at $\lesssim10$ MHz, and could make the global radio spectrum turn over at $\sim3$ MHz. Our sky map shows unique features at the ultra-long wavelengths, including a darker Galactic plane in contrast to the sky at higher frequencies, and the huge shadows of the spiral arms on the sky map. It would be a useful guidance for designing the future ultra-long wavelength observations.

description: Extensive air shower detectors of gamma rays in the sub-PeV energy region provide a new and relatively unexplored window for dark matter searches. Here we derive some implications of the recently published Tibet AS$_γ$ data for decaying dark matter candidates. The available spectral information is already useful in obtaining competitive constraints, surpassing existing limits above 10 PeV mass for hadronic or massive boson final states. This is particularly true if accounting for a benchmark astrophysical background of Galactic cosmic rays in the (0.1-1) PeV range. By relying on the arrival distribution of the photons, we show that significantly better sensitivity can be attained, comparable or better than IceCube also for most leptonic final states. Full data exploitation requires however further information disclosure.

An Improved Model for the Spectra of Disks of Nova-like Variables
Creators: name: Hubeny, Ivan
name: Long, Knox S.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The spectra arising from the disks of nova-like variables show many of the features seen in stellar atmospheres. They are typically modelled either from an appropriated weighted set of stellar atmospheres or a disk atmosphere with energy is dissipated near the disk plane, with the effective temperature distribution expected from a steady state accretion disk. However these models generally over-predict the depth of the Balmer jump and the slope of the spectrum in the ultraviolet. The problem is likely due to energy dissipation in the disk atmosphere, which produces a flatter vertical temperature profile than is observed in stars. Here, we provide validation for this hypothesis in the form of spectra generated using the stellar atmosphere code TLUSTY using a parametric prescription for energy dissipation as a function of depth and closely match the spectrum of the nova-like IX Vel over the wavelength range 1150-6000 Å.

Perceptivist mathematics education
Creators: name: Copeland, Brian Dwight
Publisher: name: University of British Columbia
Year: 2010

description: The aim of this paper is to outline and apply a perceptivist philosophy of education and a constructivitist theory of knowledge acquisition to a problem in secondary mathematics education. A working summary of perceptivism and constructivism is provided and a program and lesson materials are discussed within the context of perceptivist-constructivist ideas. The main thesis of this paper is that the way to translate perceptivist-constructivist ideas into practice in mathematics is to emphasize activities that lead to actual perceptions. The traditional problem with this is that often the computational abilities needed to deal with reality are too much for most students to deal with. The information age innovation that makes a utilitarian mathematics education more possible now, where it was not possible previously, is the development of the personal computer. The computer can act as an information processing "step up transformer" to boost students past computation to real, perceptual mathematics. The practical part of the paper consists of lessons aimed at a partial realization of perceptivism-constructivism in the classroom. The lessons concern concepts and skills from the traditional secondary mathematics curriculum areas; arithmetic, algebra, elementary function theory and calculus. The paper concludes with a report on field tests of the materials in the secondary classrooms of the author.
An analytic philosophy of design and design education : major paradigms and implications for art & design education
Creators: name: Arnold, Raymond Douglas
Publisher: name: University of British Columbia
Year: 2010

description: This study is based on the premise that both the theoretical and practical work of curriculum development requires the support of generally understood and agreed concepts and terminology. The use of the term 'design' within the fields of design methodology, art & design education, and the design professions is analyzed for the purpose of distinguishing and correlating the various domains of attached meanings. This 'Analytic Philosophy' seeks to clarify to what extent the term 'design' is reliable when applied to the task of determining the purpose and content of design-related activities within art curricula. Two major paradigms related to the notions of design as a 'problem-solving-process' and as a 'basic human capacity' are isolated and offered as dominant orientations towards design methodology and design curriculum development. Assumptions, beliefs, claims, and counter-claims seen to undergird these paradigms are mapped and analyzed along with the design-related content of Canadian provincial secondary art curriculum guides. It is shown that the term 'design' commonly finds different meanings within different contexts and that agreement regarding the meaning of the term is difficult to establish both within and across the various design and art & design education domains. It is also evident that many of the claims which work to support the theoretical frameworks of the paradigms cannot be substantiated. It is concluded that the notion of 'design', as a result, remains conceptually and contextually vague and ambiguous. It is further concluded that while such conceptual confusion might be of little consequence to the practical activities of the design professions, it can serve to complicate and inhibit communications and work particularly related to design education issues and curriculum development. Therefore the term 'design' is seen as unreliable when applied to the task of determining the purpose and content of design-related activities within art curricula.

description: High-Efficiency Video Coding (HEVC) surpasses its predecessors in encoding efficiency by introducing new coding tools at the cost of an increased encoding time-complexity. The Coding Tree Unit (CTU) is the main building block used in HEVC. In the HEVC standard, frames are divided into CTUs with the predetermined size of up to 64x64 pixels. Each CTU is then divided recursively into a number of equally sized square areas, known as Coding Units (CUs). Although this diversity of frame partitioning increases encoding efficiency, it also causes an increase in the time complexity due to the increased number of ways to find the optimal partitioning. To address this complexity, numerous algorithms have been proposed to eliminate unnecessary searches during partitioning CTUs by exploiting the correlation in the video. In this paper, existing CTU depth decision algorithms for HEVC are surveyed. These algorithms are categorized into two groups, namely statistics and machine learning approaches. Statistics approaches are further subdivided into neighboring and inherent approaches. Neighboring approaches exploit the similarity between adjacent CTUs to limit the depth range of the current CTU, while inherent approaches use only the available information within the current CTU. Machine learning approaches try to extract and exploit similarities implicitly. Traditional methods like support vector machines or random forests use manually selected features, while recently proposed deep learning methods extract features during training. Finally, this paper discusses extending these methods to more recent video coding formats such as Versatile Video Coding (VVC) and AOMedia Video 1(AV1).

description: Certificates ensure the authenticity of users' public keys, however their overhead (e.g., certificate chains) might be too costly for some IoT systems like aerial drones. Certificate-free cryptosystems, like identity-based and certificateless systems, lift the burden of certificates and could be a suitable alternative for such IoTs. However, despite their merits, there is a research gap in achieving compatible identity-based and certificateless systems to allow users from different domains (identity-based or certificateless) to communicate seamlessly. Moreover, more efficient constructions can enable their adoption in resource-limited IoTs. In this work, we propose new identity-based and certificateless cryptosystems that provide such compatibility and efficiency. This feature is beneficial for heterogeneous IoT settings (e.g., commercial aerial drones), where different levels of trust/control is assumed on the trusted third party. Our schemes are more communication efficient than their public key based counterparts, as they do not need certificate processing. Our experimental analysis on both commodity and embedded IoT devices show that, only with the cost of having a larger system public key, our cryptosystems are more computation and communication efficient than their certificate-free counterparts. We prove the security of our schemes (in the random oracle model) and open-source our cryptographic framework for public testing/adoption.

Colour pairs for constraining the age and metallicity of stellar populations

description: Using a widely used stellar population synthesis model, we study the ability of using pairs of AB system colours to break the well-known stellar age--metallicity degeneracy and give constraints on the two stellar-population parameters (age and metallicity). The relative age and metallicity sensitivities of AB system colours that relate to u, B, g, V, r, R, i, I, z, J, H, and K bands are presented, and the abilities of various colour pairs for breaking the age--metallicity degeneracy are quantified by an uncertainty parameter (UP) method. Our results suggest that a few pairs of colours can be used to constrain the two above stellar-population parameters. This will be very useful for exploring the stellar populations of distant galaxies. In detail, colour pairs [(r-K), (u-R)] and [(r-K), (u-r)] are shown to be the best pairs for estimating stellar ages and metallicities. They can constrain two stellar-population parameters on average with age uncertainties less than 3.89 Gyr and metallicity uncertainties less than 0.34 dex for typical uncertainties in colours. Some other colour pairs, such as [(R-K), (u-R)], [(I-K), (u-R)], [(R-K), (u-r)] and [(i-J), (u-R)], can possibly be used for constraining the two parameters, too. As a whole, our results suggest that colours relating to both UBVRIJHK and ugriz magnitudes are much better than either UBVRIJHK colours or ugriz colours for breaking the well-known degeneracy. The results also show that the stellar ages and metallicities of galaxies observed by the Sloan Digital Sky Survey (SDSS) and the Two-Micron All-Sky Survey (2MASS) can be estimated via photometry data. It is also shown that the colours can be used in conjunction with line indices to measure stellar-population parameters.

Predictions for sin 2(beta/phi_1)_eff in b->s penguin dominated modes

description: We provide a review of predictions for sin 2beta_eff in b->s penguin dominated modes based on 1/m_b expansion and/or SU(3) flavor symmetry. The experimental results are consistently lower than the theoretical predictions. In order to interpret whether this effect is a sign of new physics contributions or can be explained away within the Standard Model a theoretical input cannot be avoided. The effect survives at a level larger than 2.1 sigma in a conservative average over different modes that includes theoretical predictions.

description: Associated to a differential BV algebra are two differential graded Lie algebras: we call one classical and the other, which contains a formal h-bar parameter, quantum. The classical dgLa is always smooth formal. In this paper, we give necessary and sufficient conditions for the quantum dgLa to be smooth formal. These conditions are equivalent to the degeneration of a version of the noncommutative Hodge to de Rham spectral sequence. References added.

Electronic structure of the zigzag spin-chain compound In$_2$VO$_5$

description: Band structure calculations within the local spin-density approximation are presented in order to investigate the electronic and magnetic properties of the zigzag spin-chain compound In$_2$VO$_5$. The essential structural feature of the system is a double chain of VO$_6$-octahedra, which leads to competing intrachain and interchain magnetic couplings. Frustration of the spin-chains is expected for the proposed antiferromagnetic ordering at low temperatures. However, the band calculations show that the experimental room temperature crystal structure is incompatible with antiferromagnetism. Both the intrachain and interchain coupling is found to be ferromagnetic.

Elasticity with Arbitrarily Shaped Inhomogeneity

description: A classical problem in elasticity theory involves an inhomogeneity embedded in a material of given stress and shear moduli. The inhomogeneity is a region of arbitrary shape whose stress and shear moduli differ from those of the surrounding medium. In this paper we present a new, semi-analytic method for finding the stress tensor for an infinite plate with such an inhomogeneity. The solution involves two conformal maps, one from the inside and the second from the outside of the unit circle to the inside, and respectively outside, of the inhomogeneity. The method provides a solution by matching the conformal maps on the boundary between the inhomogeneity and the surrounding material. This matching converges well only for relatively mild distortions of the unit circle due to reasons which will be discussed in the article. We provide a comparison of the present result to known previous results.
