description: Recently, a number of two-participant all-versus-nothing Bell experiments have been proposed. Here, we give local realistic explanations for these experiments. More precisely, we examine the scenario where a participant swaps his entanglement with two other participants and then is removed from the experiment; we also examine the scenario where two particles are in the same light cone, i.e. belong to a single participant. Our conclusion is that, in both cases, the proposed experiments are not convincing proofs against local realism.

Automatic Differentiation in PCF

Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: We study the correctness of automatic differentiation (AD) in the context of a higher-order, Turing-complete language (PCF with real numbers), both in forward and reverse mode. Our main result is that, under mild hypotheses on the primitive functions included in the language, AD is almost everywhere correct, that is, it computes the derivative or gradient of the program under consideration except for a set of Lebesgue measure zero. Stated otherwise, there are inputs on which AD is incorrect, but the probability of randomly choosing one such input is zero. Our result is in fact more precise, in that the set of failure points admits a more explicit description: for example, in case the primitive functions are just constants, addition and multiplication, the set of points where AD fails is contained in a countable union of zero sets of non-identically-zero polynomials.
Hamiltonian formulations for perturbed dissipationless plasma equations

description: The Hamiltonian formulations for the perturbed Vlasov-Maxwell equations and the perturbed ideal magnetohydrodynamics (MHD) equations are expressed in terms of the perturbation derivative $\partial{\cal F}/\partialε\equiv [{\cal F}, {\cal S}]$ of an arbitrary functional ${\cal F}[\vbψ]$ of the Vlasov-Maxwell fields $\vbψ = ({\sf f},{\bf E},{\bf B})$ or the ideal MHD fields $\vbψ = (ρ,{\bf u},s,{\bf B})$, which are assumed to depend continuously on the (dimensionless) perturbation parameter $ε$. Here, $[\;,\;]$ denotes the functional Poisson bracket for each set of plasma equations and the perturbation {\it action} functional ${\cal S}$ is said to generate dynamically accessible perturbations of the plasma fields. The new Hamiltonian perturbation formulation introduces a framework for functional perturbation methods in plasma physics and highlights the crucial roles played by polarization and magnetization in Vlasov-Maxwell and ideal MHD perturbation theories. One application considered in this paper is a formulation of plasma stability that guarantees dynamical accessibility and leads to a natural generalization to higher-order perturbation theory.

description: This paper describes the OI Exchange Format, a standard for exchanging calibrated data from optical (visible/infrared) stellar interferometers. The standard is based on the Flexible Image Transport System (FITS), and supports storage of the optical interferometric observables including squared visibility and closure phase -- data products not included in radio interferometry standards such as UV-FITS. The format has already gained the support of most currently-operating optical interferometer projects, including COAST, NPOI, IOTA, CHARA, VLTI, PTI, and the Keck Interferometer, and is endorsed by the IAU Working Group on Optical Interferometry. Software is available for reading, writing and merging OI Exchange Format files.

One version was made using the application Aikuma on an Android phone and the other was made simultaneously with a field recorder. Using the Aikuma app, Tchatchouang first recorded the text in Tswefap (these are the two recordings with '-text' in the title). The application then allows the user to listen back to short portions of the original recording and record a translation. The file with '-interpret' in the title contains these translations recorded via Aikuma. The file with '-trans' in the title contains the recording of the entire process of playback and translation recorded simultaneously with the field recorder. Finally, Aikuma produces a recording with the text and translation recordings interleaved (this is the recording with '-interleaved' in the title). The remaining files in the bundle are the Aikuma files required to produce the interleaved recording.

description: Motivated by the recent discovery of a low temperature spin liquid phase in layered organic compound $κ$-(ET)$_2$Cu$_2$(CN)$_3$ which becomes a superconductor under pressure, we examine the phase transition of Mott insulating and superconducting (SC) states in a Hubbard-Heisenberg model on an anisotropic triangular lattice. We use a renormalized mean field theory to study the Gutzwiller projected BCS wavefucntions. The half filled electron system is a Mott insulator at large on-site repulsion $U$, and is a superconductor at a moderate $U$. The symmetry of the SC state depends on the anisotropy, and is gapful with $d_{x^2-y^2}+id_{xy}$ symmetry near the isotropic limit and is gapless with $d_{x^2-y^2}$ symmetry at small anisotropy ratio.

description: Two-dimensional SU$(N)$ gauge theory coupled to a Majorana fermion in the adjoint representation is a nice toy model for higher-dimensional gauge dynamics. It possesses a multitude of "gluinoball" bound states whose spectrum has been studied using numerical diagonalizations of the light-cone Hamiltonian. We extend this model by coupling it to $N_f$ flavors of fundamental Dirac fermions (quarks). The extended model also contains meson-like bound states, both bosonic and fermionic, which in the large-$N$ limit decouple from the gluinoballs. We study the large-$N$ meson spectrum using the Discretized Light-Cone Quantization (DLCQ). When all the fermions are massless, we exhibit an exact $\mathfrak{osp}(1|4)$ symmetry algebra that leads to an infinite number of degeneracies in the DLCQ approach. More generally, we show that many single-trace states in the theory are threshold bound states that are degenerate with multi-trace states. These exact degeneracies can be explained using the Kac-Moody algebra of the SU$(N)$ current. We also present strong numerical evidence that additional threshold states appear in the continuum limit. Finally, we make the quarks massive while keeping the adjoint fermion massless. In this case too, we observe some exact degeneracies that show that the spectrum of mesons becomes continuous above a certain threshold. This demonstrates quantitatively that the fundamental string tension vanishes in the massless adjoint QCD$_2$.

Women interrupted : determinants of women's employment exit and return in Indonesia

description: In Western countries, marriage and childbearing have consistently been shown to be major stages in the life cycle that affect women's employment continuity. Women in these countries generally withdraw from the workforce at marriage or at the onset of motherhood. However, in Indonesia, the characteristics and effects of such an interrupting feature in women's working patterns still remain unclear. Existing studies fail to explore the dynamic nature of employment behavior, particularly employment interruption which is a strong feature of women's labour market behavior. This thesis examines the factors that contribute to interruptions in women's employment in Indonesia. It adopts a discrete-time event history analysis to explore the determinants of female's transition out from and back into employment. It pays specific attention to the effect of the family life cycle on women's decision to leave and return to employment. Using a longitudinal data collection called the Indonesia Family Life Survey (IFLS), this thesis seeks to answer four questions: (1) To what extent and when do women experience work interruption?; (2) To what extent do marriage and childbearing influence women to leave employment?; (3) To what extent does being in the later stages of childrearing influence women to return to employment?; (4) What are the roles of education and employment characteristics in determining women's decisions to leave and return to work? The results of the analyses conducted in this study show that work interruption is common among women in Indonesia. Marriage and the onset of motherhood have been found to have a positive association with the risk of leaving employment. In particular, the effect of entering marriage on employment exit is stronger for women working in low-level occupations and for women with junior and senior secondary levels of education. This study also finds that having tertiary education and working in the public sector reduces the risk of experiencing an employment interruption. Meanwhile, the later stages of childrearing, measured by the age of the youngest child, have been found to have no significant effect on women's employment return. However, the presence of children does have a strong effect on the risk of returning to work in the informal rather than in the formal sector. The risk of reentering employment after a work interruption is also positively associated with the number of young children, indicating that women would return to work more quickly when the economic burden in the family increases. This study also finds that formal workers tend to be employed in the same sector when they decide to return to work.
Conceptions of success in education for three classes of Nunavut Arctic College students
Creators: name: Gooding, John Douglas
Publisher: name: University of British Columbia
Year: 2009

description: "Success" in education means different things to different people. The purpose of this study was to examine conceptions of success (in education) held by some students at Nunavut Arctic College. The author is a white male from southern Canada and had not been to the Arctic prior to this study. As such, it was necessary to employ a participatory and respectful methodology. ' In three separate procedures, classes of Nunavut Arctic college students were given index cards and asked to describe what it means to be successful in education. As a class, we arranged the cards into common categories on the floor in front of the classroom desks. Some students wrote that success in education meant getting a good job. Some reported that they learned best when they could understand what was going on in a class. We decided as a class where each card belonged. Conceptions of success in education emerged as groups of cards were given titles, such as, "Understanding" or "Sharing knowledge." In the final procedure, another group of students was interviewed with a tape recorder to explore their conceptions in more depth. "Success" in education in the Arctic (and elsewhere) typically has to do with securing knowledge for personal development. Secondly, it is concerned with instrumental or pragmatic concerns like getting a job. For most people "success" in education involves a mix of personal and instrumental factors. Hence, for the purposes of this study the author used a heuristic device wherein "personal" and "instrumental" conceptions of success could be plotted. Students' conceptions were graphed along the two dimensions of instrumental application and personal development. Five conceptions emerged from the final study: "Understanding", "Sharing", "Reaching goals in education", "Money" and "Certificate". The conception "Understanding" was graphed in an area of low instrumental application/high personal development; "Sharing knowledge" and "Reaching goals in education" were graphed in an area of high instrumental application/high personal development; "Money" was graphed in an area of low instrumental application/low personal development; and "Certificate" was graphed in an area of high instrumental application/low personal development.

description: High-redshift 21-cm observations will provide crucial insights into the physical processes of the Epoch of Reionization. Next-generation interferometers such as the Square Kilometer Array will have enough sensitivity to directly image the 21-cm fluctuations and trace the evolution of the ionizing fronts. In this work, we develop an inferential approach to recover the sources and IGM properties of the process of reionization using the number and, in particular, the morphological pattern spectra of the ionized regions extracted from realistic mock observations. To do so, we extend the Markov Chain Monte Carlo analysis tool 21CMMC by including these 21-cm tomographic statistics and compare this method to only using the power spectrum. We demonstrate that the evolution of the number-count and morphology of the ionized regions as a function of redshift provides independent information to disentangle multiple reionization scenarios because it probes the average ionizing budget per baryon. Although less precise, we find that constraints inferred using 21-cm tomographic statistics are more robust to the presence of contaminants such as foreground residuals. This work highlights that combining power spectrum and tomographic analyses more accurately recovers the astrophysics of reionization.

description: Due to quantum fluctuations, spacetime is foamy on small scales. The degree of foaminess is found to be consistent with holography, a principle prefigured in the physics of black hole entropy. It has bearing on the ultimate accuracies of clocks and measurements and the physics of quantum computation. Consistent with existing archived data on active galactic nuclei from the Hubble Space Telescope, the application of the holographic spacetime foam model to cosmology requires the existence of dark energy which, we argue, is composed of an enormous number of inert "particles" of extremely long wavelength. We suggest that these "particles" obey infinite statistics in which all representations of the particle permutation group can occur, and that the nonlocality present in systems obeying infinite statistics may be related to the nonlocality present in holographic theories. We also propose to detect spacetime foam by looking for halos in the images of distant quasars, and argue that it does not modify the GZK cutoff in the ultra-high energy cosmic ray spectrum and its contributions to time-of-flight differences of high energy gamma rays from distant GRB are too small to be detectable.

description: In this paper, we define the higher Frobenius-Schur (FS-)indicators for finite-dimensional modules $V$ of a semisimple quasi-Hopf algebra $H$ via the categorical counterpart developed in \cite{NS05}. We prove that this definition of higher FS-indicators coincides with the higher indicators introduced by Kashina, Sommerhäuser, and Zhu when $H$ is a Hopf algebra. We also obtain a sequence of canonical central elements of $H$, which is invariant under gauge transformations, whose values, when evaluated by the character of an $H$-module $V$, are the higher Frobenius-Schur indicators of $V$. As an application, we show that FS-indicators are sufficient to distinguish the four gauge equivalence classes of semisimple quasi-Hopf algebras of dimension eight corresponding to the four fusion categories with certain fusion rules classified by Tambara and Yamagami. Three of these categories correspond to well-known Hopf algebras, and we explicitly construct a quasi-Hopf algebra corresponding to the fourth. We also derive explicit formulae for FS-indicators for some quasi-Hopf algebras associated to group cocycles.

The relation between the pre-scission neutron multiplicity and each reaction process having different reaction time is investigated. In order to study the fusion-fission process accompanied by neutron emission, the fluctuation-dissipation model combined with a statistical model is employed. It is found that the fusion-fission process and the quasi-fission process are clearly distinguished in correlation with the pre-scission neutron multiplicity.

description: The previously proposed ansatz for density cumulant theory that combines orbital-optimization and a parameterization of the 2-electron reduced density matrix cumulant in terms of unitary coupled cluster amplitudes (OUDCT) is carefully examined. Formally, we elucidate the relationship between OUDCT and orbital-optimized unitary coupled cluster theory and show the existence of near-zero denominators in the stationarity conditions for both the exact and some approximate OUDCT methods. We implement methods of the OUDCT ansatz restricted to double excitations for numerical study, up to the fifth commutator in the Baker-Campbell-Hausdorff expansion. We find that methods derived from the ansatz beyond the previously known ODC-12 method tend to be less accurate for equilibrium properties and less reliable when attempting to describe $H2$ dissociation. New developments are needed to formulate more accurate DCT variants.

description: gaps among its students. Students of color and those from lower-income backgrounds often have poorer academic attainment compared to White students and those from higher-income families. Understanding the processes that could reduce disparities in academic achievement are critical to improving educational practice. Teachers’ and parents’ expectations for the educational futures of youth strongly influence how well the youth do academically. Using data from a large, nationally‐representative sample of students, PRC faculty scholar Aprile Benner, PRC graduate student trainee Celeste Fernandez, and colleagues, find that high teacher expectations are critical for youth academic achievement and can mitigate the negative effects of low parent expectations. They argue that improving educational expectations that teachers hold for all students has the potential to greatly assist youth who are often marginalized in educational settings.

description: The 11th magnitude star LS IV -08 3 has been classified previously as an OB star in the Luminous Stars survey, or alternatively as a hot subdwarf. It is actually a binary star. We present spectroscopy, spectroscopic orbital elements, and time series photometry, from observations made at the Kitt Peak National Observatory 2.1m, Steward Observatory 2.3m, MDM Observatory 1.3m and 2.4m, Hobby-Eberly 9.2m, and Michigan State University 0.6m telescopes. The star exhibits emission of varying strength in the cores of H and He I absorption lines. Emission is also present at 4686 Angstroms (He II) and near 4640/4650 Angstroms (N III/C III). Time-series spectroscopy collected from 2005 July to 2007 June shows coherent, periodic radial velocity variations of the H-alpha line, which we interpret as orbital motion with a period of 0.1952894(10) days. High-resolution spectra show that there are two emission components, one broad and one narrow, moving in antiphase, as might arise from an accretion disk and the irradiated face of the mass donor star. Less coherent, low-amplitude photometric variability is also present on a timescale similar to the orbital period. Diffuse interstellar bands indicate considerable reddening, which however is consistent with a distance of ~100-200 pc. The star is the likely counterpart of a weak ROSAT X-ray source, whose properties are consistent with accretion in a cataclysmic variable (CV) binary system. We classify LS IV -08 3 as a new member of the UX UMa subclass of CV stars.

description: The classical Eisenhart lift is a method by which the dynamics of a classical system subject to a potential can be recreated by means of a free system evolving in a higher-dimensional curved manifold, known as the lifted manifold. We extend the formulation of the Eisenhart lift to quantum systems, and show that the lifted manifold recreates not only the classical effects of the potential, but also its quantum mechanical effects. In particular, we find that the solutions of the Schrodinger equations of the lifted system reduce to those of the original system after projecting out the new degrees of freedom. In this context, we identify a conserved quantum number, which corresponds to the lifted momentum of the classical system. We further apply the Eisenhart lift to Quantum Field Theory (QFT). We show that a lifted field space manifold is able to recreate both the classical and quantum effects of a scalar field potential. We find that, in the case of QFT, the analogue of the lifted momentum is a quantum charge that is conserved not only in time, but also in space. The different possible values for this charge label an ensemble of Fock spaces that are all disjoint from one another. The relevance of these extended Fock spaces to the cosmological constant and gauge hierarchy problems is considered.

In the disordered case with all the states being localized, the resonant tunneling, which is topologically protected, plays a crucial role, and enhances the dielectric response by a factor 30~40 compared with the pure case. Realization of this idea with accessible materials/structures is also discussed.

description: We propose here a new symplectic quantization scheme, where quantum fluctuations of a scalar field theory stem from two main assumptions: relativistic invariance and equiprobability of the field configurations with identical value of the action. In this approach the fictitious time of stochastic quantization becomes a genuine additional time variable, with respect to the coordinate time of relativity. This proper time is associated to a symplectic evolution in the action space, which allows one to investigate not only asymptotic, i.e. equilibrium, properties of the theory, but also its non-equilibrium transient evolution. In this paper, which is the first one in a series of two, we introduce a formalism which will be applied to general relativity in the companion work "Symplectic quantization II".

title: Colonial Lores in Legal Codes: Cast(e)ing Gender Deviance in Colonial India (1860-1901)
Creators: name: Semmalar, Gee Imaan
Publisher: name: University of Kent
Year: 2024

description: This thesis explores the production and regulation of gender deviance through and as caste in the mid to late nineteenth century British India. To explore the conditions that enabled this production, I develop a new conceptual and methodological lens of polymorphic colonialities. Methodologically, the lens of polymorphic colonialities offers a way to place caste and gender beside each other to understand them as co-constitutive. Conceptually, it enables an analysis of power through the structural encounter and transformation of the colonialities of caste and British rule. By critically reading the colonial archives at The British Library and The National Archives of India, the thesis develops and refines the lens of polymorphic colonialities by analysing the production of gender deviance through and as caste in three different forms of knowledge: ethnographic photography from 1860-1890 (visual form), The Criminal Tribes Act 1871 (legal form) and the census exercises from 1871-1901 (enumerative form). The thesis argues that gender deviance was produced in ethnographic photography through racialised visual codes of caste. In the Criminal Tribes Act 1871, gender deviance was criminalised through notions of hereditary "caste criminality". In the British Indian census, gender deviance was produced as caste through the creation of a hitherto non-existent caste category of "eunuchs" or "hijras", variously enumerated based on occupational criteria, social precedence ranking of caste and frames of immorality. By introducing and developing the lens of polymorphic colonialities to demonstrate how gender deviance was produced through and as caste in a highly adaptable process enabled by the epistemic and political encounter between caste and British rule, the thesis makes an intervention in gender and sexuality studies and legal historiographies.
On the formation of van der Waals complexes through three-body recombination

description: In this work, we show that van der Waals molecules X-RG (where RG is the rare gas atom) may be created through direct three-body recombination collisions, i.e., X + RG + RG $\rightarrow$ X-RG + RG. In particular, the three-body recombination rate at temperatures relevant for buffer gas cell experiments is calculated via a classical trajectory method in hyperspherical coordinates [J. Chem. Phys. 140, 044307 (2014)]. As a result, it is found that the formation of van der Waals molecules in buffer gas cells (1 K $\lesssim T \lesssim 10$ K) is dominated by the long-range tail (distances larger than the LeRoy radius) of the X-RG interaction. For higher temperatures, the short-range region of the potential becomes more significant. Moreover, we notice that the rate of formation of van der Walls molecules is of the same order of magnitude independently of the chemical properties of X. As a consequence, almost any X-RG molecule may be created and observed in a buffer gas cell under proper conditions.

Beginning action research : enhancing autonomous learning in a medical radiography program
Creators: name: McLaughlin, Rita
Publisher: name: University of British Columbia

description: As a clinical instructor in a medical radiography program, I began to wonder why some students reported feeling overwhelmed in the initial days of the practicum portion of the program. Having tried repeatedly to remedy the problem, I decided to take a closer look. I hoped in the process to gain some insights into what overwhelmed some students and not others and to understand the effects of being overwhelmed in the initial days of the practicum. This thesis outlines the action research approach used to study the practicum. The principal participants in the practicum (the students, the radiology technologists, and myself, the clinical instructor) contributed to the generation of the data that formed our research, over the four-week practicum. The students and technologists participated in interviews, which were transcribed from audiotapes and distributed to the group for reading. When we read the typed material, we thought about our own similar experiences (or different experiences, if this was so). The problems that arose from the readings became our problems, and the students and I met to voice or express them as best we could. There were four meetings; from each meeting we chose an action plan. Each of us tried to implement the plan the following week. As we implemented the plan we also evaluated the outcomes we experienced. I had a notion that the student, who was set on obtaining his or her learning objectives, would be an autonomous learner and would be less likely to be overwhelmed. So my intention during the practicum was to look for ways of enhancing autonomous learning. What I found was that the very process of action research enhanced autonomous learning in the students.

Vortex Splitting in Subcritical Nonlinear Schrodinger Equation

description: Vortices and axisymmetric vortex rings are considered in the framework of the subcritical nonlinear Schrodinger equations. The higher order nonlinearity present in such systems models many-body interactions in superfluid systems and allows one to study the effects of negative pressure on vortex dynamics. We find the critical pressure for which the straight-line vortex becomes unstable to radial expansion of the core. The energy of the straight-line vortices and energy, impulse and velocity of vortex rings are calculated. The effect of a varying pressure on the vortex core is studied. It is shown that under the action of the periodically varying pressure field a vortex ring may split into many vortex rings and the conditions for which this happens are elucidated. These processes are also relevant to experiments in Bose-Einstein condensates where the strength and the sign of two-body interactions can be changed via Feshbach resonance.

Validating the effects of sex differences and auditory/visual-based verbal memory on recall tasks in a virtual supermarket

description: Virtual reality (VR), with its superior ecological validity, offers a potential new method for assessing and training memory recall. To further validate the utilization of VR, the current study explores the effects of sex and auditory/visual-based verbal memory—both closely related to memory recall in everyday shopping behavior—on recall tasks both inside and outside of a virtual supermarket. The International Shopping List Test (ISLT) verbal recall tasks were used in the experiment. To examine whether the same effects exist in VR, a self-developed virtual supermarket was applied. The results indicate that women and those who were in the visual-based group for verbal memory performed better both inside and outside the VR. The study further compares users’ spatial-based visual memory encoding with verbal memory retrieval in VR to determine whether they align with theoretical assumptions and prior studies. The findings support the view that women’s superior visual memory may be compromised in the virtual supermarket due to their relatively lower self-reported sense of direction (SOD) and higher levels of wayfinding anxiety compared to men. Empirical and practical implications based on these findings are discussed in the study.

description: The superconducting state of Mg$^{10}$B$_{2}$ is investigated by specific heat measurements in detail. The specific heat in the normal state is analyzed using a recently developed computer code. This allows for an extraction of the electronic specific heat in the superconducting state with high accuracy and a fair determination of the main lattice features. One of the two investigated samples shows a hump in the specific heat at low temperatures within the superconducting state, accompanied by an unusual low value of the small gap, $Δ_π(0)=1.32 meV$, pointing to a very weak inter-band coupling. This sample allows for a detailed analysis of the contribution from the $π$-band to the electronic specific heat in the superconducting state. Therefore the usual analysis method is modified, to include the individual conservation of entropy of both bands. From analyzing the deviation function $D(t)$ of MgB$_{2}$, the theoretically predicted weak inter-band coupling scenario is confirmed.

description: Infrared and submillimetre observations of nearby Vega-like stars have revealed a number of clumpy, asymmetric dust debris disks. Previous studies using semi-analytical and numerical methods have suggested planetary companions of various mass as the likely cause of most examples of disk asymmetry. In this paper, we modify an N-body symplectic gravitational integrator to include radiation terms and conduct medium-resolution parameter searches to identify likely planetary candidates in observed Vega-like systems. We also present high resolution models of Vega and epsilon Eridani, comparing our results to those of previous authors, and a new model for Fomalhaut.
