Dimensional reduction of the ABJM model
Creators: name: Nastase, Horatiu
name: Papageorgakis, Constantinos
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We dimensionally reduce the ABJM model, obtaining a two-dimensional theory that can be thought of as a 'master action'. This encodes information about both T- and S-duality, i.e. describes fundamental (F1) and D-strings (D1) in 9 and 10 dimensions. The Higgsed theory at large VEV and large k yields D1-brane actions in 9d and 10d, depending on which auxiliary fields are integrated out. For N=1 there is a map to a Green-Schwarz string wrapping a nontrivial circle in C^4/Z_k.

Multi-User Distillation of Common Randomness and Entanglement from Quantum States

description: We construct new protocols for the tasks of converting noisy multipartite quantum correlations into noiseless classical and quantum ones using local operations and classical communications (LOCC). For the former, known as common randomness (CR) distillation, two new lower bounds on the "distillable common randomness", an operational measure of the total genuine (classical) correlations in a quantum state, are obtained. Our proof relies on a generalization of communication for omniscience (CO) [Csiszar and Narayan, IEEE Trans. Inf. Theory 50:3047-3061, 2004]. Our contribution here is a novel simultaneous decoder for the compression of correlated classical sources by random binning with quantum side information at the decoder. For the latter, we derive two new lower bounds on the rate at which Greenberger-Horne-Zeilinger (GHZ) states can be asymptotically distilled from any given pure state under LOCC. Our approach consists in "making coherent" the proposed CR distillation protocols and recycling of resources [Devetak et al. IEEE Trans. Inf. Theory 54(10):4587-4618, 2008]. The first lower bound is identical to a recent result by Vrana and Christandl [IEEE Trans. Inf. Theory 65(9):5945-5958, 2019], which is based on a combinatorial method to achieve the same rate. Our second lower bound generalises and improves upon this result, and unifies a number of other known lower bounds on GHZ distillation.

A Variational Principle for Dissipative Fluid Dynamics

description: In the variational principle leading to the Euler equation for a perfect fluid, we can use the method of undetermined multiplier for holonomic constraints representing mass conservation and adiabatic condition. For a dissipative fluid, the latter condition is replaced by the constraint specifying how to dissipate. Noting that this constraint is nonholonomic, we can derive the balance equation of momentum for viscous and viscoelastic fluids by using a single variational principle. We can also derive the associated Hamiltonian formulation by regarding the velocity field as the input in the framework of control theory.

Orientation dependence of transverse relaxation rates in magnetic resonance imaging of the newborn and adult brain
Creators: name: Bartels, Lara Maria
Publisher: name: University of British Columbia
Year: 2022

description: In MRI the transverse relaxation rate, R₂=1/T₂, shows dependence on the orientation of ordered tissue relative to the main magnetic field. In previous studies, orientation effects of R₂ relaxation in the mature brain's white matter have been found to be described by a susceptibility-based model of diffusion through local magnetic field inhomogeneities created by the diamagnetic myelin sheaths. Orientation effects in human newborn white matter have not yet been investigated. The newborn brain is known to contain very little myelin and is therefore expected to exhibit a decrease in orientation dependence driven by susceptibility-based effects. We measured R₂ orientation dependence in the white matter of human newborns. R₂ data were acquired with a 3D Gradient and Spin Echo (GRASE) sequence and fibre orientation was mapped with diffusion tensor imaging (DTI). We found orientation dependence in newborn white matter that is not consistent with the susceptibility-based model and is best described by a model of residual dipolar coupling. In the near absence of myelin in the newborn brain, these findings suggest the presence of residual dipolar coupling between motionally restricted water molecules. This has important implications for quantitative imaging methods such as myelin water imaging, and suggests orientation dependence of R₂ as a potential marker in early brain development.

description: The Birman exact sequence describes the effect on the mapping class group of a surface with boundary of gluing discs to the boundary components. We construct an analogous exact sequence for the automorphism group of a free group. For the mapping class group, the kernel of the Birman exact sequence is a surface braid group. We prove that in the context of the automorphism group of a free group, the natural kernel is finitely generated. However, it is not finitely presentable; indeed, we prove that its second rational homology group has infinite rank by constructing an explicit infinite collection of linearly independent abelian cycles. We also determine the abelianization of our kernel and build a simple infinite presentation for it. The key to many of our proofs are several new generalizations of the Johnson homomorphisms.

title: Teaching Statistical Literacy in Lincolnshire Schools: A Critical Case Study
Creators: name: Nye, Zoe Michelle
Publisher: name: The Open University
Year: 2023

description: This thesis uses a pragmatic, interpretivist multi-case study to explore the teaching of statistical literacy. Focusing on the lived experiences of three in-service secondary mathematics teachers, I develop a picture of their teaching and the influences on their professional practice whilst teaching statistics. Although research literature describes best practice for teaching statistical literacy, research with experienced in-service teachers is relatively rare and the factors which influence these teachers’ practice whilst working with the 11-16 age range have not previously been well explored.

My review of theoretical frameworks for best practice in teaching statistical literacy identified three different areas that would merit exploration. Firstly, the factors affecting teachers’ decision-making processes when planning and teaching statistics lessons. Secondly, the range of aspects which contribute to the teachers’ pedagogical subject knowledge and, thirdly, the impact of the teachers’ affective domain, such as their beliefs, values and emotional reactions to teaching statistical literacy.

Data were collected using lesson observations, semi-structured interviews, and teacher biographies, supplemented by examination data, national curricula and examination board syllabi. Analysis of the findings provides a perspective on the lived experiences of in-service secondary mathematics teachers teaching statistical literacy.

Findings indicate that external policy and social changes drive the teaching of statistical literacy. Whilst the teachers held that statistical literacy was important for building informed citizens, they felt that teaching the 11-16 age range is geared towards examination results and thus often avoided aspects of the curriculum which are rarely examined. As teaching statistical literacy gives a poor rate of return in examination marks for the teaching time invested, it is a low priority for teachers, despite its perceived usefulness.

The teachers in this study reported positive feelings towards teaching statistical literacy but described it as a ‘marmite subject’ and considered that mathematics teachers rarely have a positive attitude toward teaching it. In general, earlier positive exposure to statistics results in greater enthusiasm for teaching statistical literacy.

Teaching children in the 11-16 age range to interpret statistics would ultimately enable the population to critically engage with statistics in their adult lives without a sense of pervasive distrust. Mathematics teachers in England are currently responsible for teaching statistical literacy. My findings suggest that if we wish to build a statistically literate population, then initial teacher training and continuing professional development for teachers need to address this.

description: We use top quark pair production as a probe of top-philic non-resonant new physics. Following a low energy effective field theory approach, we calculate several key observables in top quark pair production at hadron colliders (e.g., total cross section, ttbar invariant mass distribution, forward-backward asymmetry, spin correlations) including the interference of the Standard Model with dimension-six operators. We determine the LHC reach in probing new physics after having taken into account the Tevatron constraints. In particular, we show that the gluon fusion process gg -> ttbar which remains largely unconstrained at the Tevatron is affected by only one top-philic dimension-six operator, the chromo-magnetic moment of the top quark. This operator can be further constrained by the LHC data as soon as a precision of about 20% is reached for the total ttbar cross-section. While our approach is general and model-independent, it is particularly relevant to models of Higgs and top compositeness, which we consider in detail, also in connection with ttbar ttbar and ttbar bbbar production.

On-the-fly ab initio semiclassical evaluation of third-order response functions for two-dimensional electronic spectroscopy

description: Ab initio computation of two-dimensional electronic spectra is an expanding field, whose goal is improving upon simple, few-dimensional models often employed to explain experiments. Here, we propose an accurate and computationally affordable approach, based on the single-trajectory semiclassical thawed Gaussian approximation, to evaluate two-dimensional electronic spectra. Importantly, the method is exact for arbitrary harmonic potentials with mode displacement, changes in the mode frequencies, and inter-mode coupling (Duschinsky effect), but can also account partially for the anharmonicity of the involved potential energy surfaces. We test its accuracy on a set of model Morse potentials and use it to study anharmonicity and Duschinsky effects on the linear and two-dimensional electronic spectra of phenol. We find that in this molecule, the anharmonicity effects are weak, whereas the Duschinsky rotation and the changes in the mode frequencies must be included in accurate simulations. In contrast, the widely used displaced harmonic oscillator model captures only the basic physics of the problem but fails to reproduce the correct vibronic lineshape.

description: Background—Cerebrovascular lesions are uncommon in neurofibromatosis type 1 (NF1). Case Description—We report a case of 34-year-old man with NF1 who developed posterior circulation stroke. Diffusion-weighted imaging showed acute infarcts in the right vertebra basilar artery territory. Digital subtraction angiography demonstrated significant stenosis of the basilar artery in the mid segment that was identified as the etiology of the symptoms. The vertebral arteries were tortuous and the basilar artery was ectatic. Subsequently endeavour resolute stent was placed across the lesion and post-procedure angiogram showed resolution of stenosis. Conclusion—Selective stenotic involvement of the basilar artery with ectatic vertebrobasilar circulation associated with NF1, which was successfully treated with endovascular method, was not been reported previously to our knowledge.

A coarse-grained entropy for expanding cosmologies
Creators: name: Leung, Hon Yin (Pompey)
Publisher: name: University of British Columbia
Year: 2022

description: The AdS/CFT correspondence relates quantum gravity in asymptotically anti-de Sitter (AdS) spacetimes to conformal field theories (CFT) living on its boundary. It is the most explicitly realised example of the holographic principle to date; holographic descriptions for more general spacetimes remain poorly understood. In seeking a microscopic description of cosmology through the holographic principle, this thesis explores the notion of a coarse-grained entropy over quantum gravitational degrees of freedom for expanding universes. The Engelhardt-Wall construction for the outer entropy is a coarse-grained generalization of the Hubeny-Rangamani-Takayanagi (HRT) formula for the von Neumann entropy. It admits a timelike thermodynamic second law for boundary operators with the bulk interpretation of coarse-graining over progressively larger regions to the interior of marginally trapped surfaces which foliate spacelike holographic screens. As holographic screens are generic objects in general relativity, a reasonable question to ask is whether we can define an analogous coarse-grained entropy for general spacetimes as a guide for probing the class of admissible underlying microscopic degrees of freedom. We show that expanding Friedmann-Lemaître-Robertson-Walker (FLRW) spacetimes admit everywhere timelike holographic screens and are thus prime candidates for a generalisation of the Engelhardt-Wall construction. After motivating the formulation of the future entropy as a cosmological coarse-grained entropy defined through a maximin prescription, we show by construction that it can always be expressed as the area of marginally anti-trapped surfaces foliating timelike holographic screens in expanding universes. In this manner, the future entropy enjoys an interpretation of quantifying the ignorance of the past subject to data fixed in the future. We then explicitly carry out our construction for spatially flat, expanding FLRW spacetimes and write an expression for the future entropy which increases with proper time as expected. Although the future entropy as we have defined is a purely geometric quantity, we entertain the possibility for a true statistical interpretation as a coarse-grained entropy which obeys a thermodynamic second law. Our hope is that the correct class of holographic theories for cosmological spacetimes would be able to reproduce our result given an appropriate coarse-graining procedure over microscopic degrees of freedom.
Which form of the molecular Hamiltonian is the most suitable for simulating the nonadiabatic quantum dynamics at a conical intersection?

description: Choosing an appropriate representation of the molecular Hamiltonian is one of the challenges faced by simulations of the nonadiabatic quantum dynamics around a conical intersection. The adiabatic, exact quasidiabatic, and strictly diabatic representations are exact and unitary transforms of each other, whereas the approximate quasidiabatic Hamiltonian ignores the residual nonadiabatic couplings in the exact quasidiabatic Hamiltonian. A rigorous numerical comparison of the four different representations is difficult because of the exceptional nature of systems where the four representations can be defined exactly and the necessity of an exceedingly accurate numerical algorithm that avoids mixing numerical errors with errors due to the different forms of the Hamiltonian. Using the quadratic Jahn-Teller model and high-order geometric integrators, we are able to perform this comparison and find that only the rarely employed exact quasidiabatic Hamiltonian yields nearly identical results to the benchmark results of the strictly diabatic Hamiltonian, which is not available in general. In this Jahn-Teller model and with the same Fourier grid, the commonly employed approximate quasidiabatic Hamiltonian led to inaccurate wavepacket dynamics, while the Hamiltonian in the adiabatic basis was the least accurate, due to the singular nonadiabatic couplings at the conical intersection.

description: We investigate the possibility of a fourth sequential generation in the lepton sector. Assuming neutrinos to be Majorana particles and starting from a recent - albeit weak - evidence for a non-zero admixture of a fourth generation neutrino from fits to weak lepton and meson decays we discuss constraints from neutrinoless double beta decay, radiative lepton decay and like-sign dilepton production at hadron colliders. Also an idea for fourth generation neutrino mass model building is briefly outlined. Here we soften the large hierarchy of the neutrino masses within an extradimensional model that locates each generation on different lepton number violating branes without large hierarchies.

Stretching and folding versus cutting and shuffling: An illustrated perspective on mixing and deformations of continua

description: We compare and contrast two types of deformations inspired by mixing applications -- one from the mixing of fluids (stretching and folding), the other from the mixing of granular matter (cutting and shuffling). The connection between mechanics and dynamical systems is discussed in the context of the kinematics of deformation, emphasizing the equivalence between stretches and Lyapunov exponents. The stretching and folding motion exemplified by the baker's map is shown to give rise to a dynamical system with a positive Lyapunov exponent, the hallmark of chaotic mixing. On the other hand, cutting and shuffling does not stretch. When an interval exchange transformation is used as the basis for cutting and shuffling, we establish that all of the map's Lyapunov exponents are zero. Mixing, as quantified by the interfacial area per unit volume, is shown to be exponentially fast when there is stretching and folding, but linear when there is only cutting and shuffling. We also discuss how a simple computational approach can discern stretching in discrete data.

This was an important limiting factor as the most fragile - hence precious - meteorites must be recovered rapidly to avoid their alteration. Aims: The Fireball Recovery and InterPlanetary Observation Network (FRIPON) scientific project was designed to overcome this limitation. This network comprises a fully automated camera and radio network deployed over a significant fraction of western Europe and a small fraction of Canada. As of today, it consists of 150 cameras and 25 European radio receivers and covers an area of about 1.5 million square kilometers.

description: Our model calculations performed in the frame of the Relativistic Mean Field (RMF) approach show how important are the modifications of nucleon Structure Function (SF) in Nuclear Matter (NM) above the saturation point. They originated from the conservation of a parton longitudinal momenta - essential in the explanation of the EMC effect at the saturation point of NM. For higher density the finite pressure corrections emerge from the Hugenholtz -van Hove (HH) theorem valid for NM and asks to modify the nucleon SF. The density evolution of the nuclear SF seems to be stronger for higher densities. Here we show that the course of Equation o State (EoS) in our modified Walecka model is very close to that obtained from extensive DBHF calculations with a Bonn A potential. The nuclear compressibility decreases. Our model - a nonlinear extension of nuclear RMF, has no additional parameters.

description: The purpose of this study was to identify the relationships between motivations to have sexual intercourse and condom use. 148 undergraduate students participated from the University of New Mexico. Motivation to have sexual intercourse as well as past sexual history was assessed. The association between condom use, relationship status and the eight subscales of the AMORE questionnaire were examined. Results indicated that the relationship between motivation to engage in sexual intercourse, relationship status and condom use is a complex one.

description: A database of DIII-D plasmas without ELMs compares the operating space and plasma performance of stationary no-ELM regimes: RMP-ELM suppression, QH-mode, I-mode, EDA H-mode, L-mode, and negative triangularity L-mode (Neg-D). Operational space is documented in terms of engineering and physics parameters, revealing divergent constraints. Some operational space discriminants (such as pedestal collisionality) are well known, while others, such as low torque & safety factor, or high power & density, are less commonly emphasized. Normalized performance (confinement quality and normalized pressure) also discriminate the no-ELM regimes and favor the regimes tolerant to power in DIII-D: RMP, QH, and Neg-D. Absolute performance (triple product $\langle p\rangleτ$) also discriminates no-ELM regimes and is found to rise linearly with IaB and also benefits from tolerance to power. The highest normalized performance using the metric $\langle p\rangleτ$/IaB is found in QH and RMP regimes. Though comparable QH and RMP performance is found, the pedestal pressure (p_ped) is very different. p_ped in RMP plasmas is relatively low, and the best performance is found with a high core $\langle p\rangle$ fraction alongside high core rotation, consistent with an ExB shear confinement enhancement. p_ped of QH plasmas is significantly higher than RMP, and QH performance does not correlate with core rotation. However, the highest QH p_ped are found with high carbon fraction. While normalized performance of Neg-D plasmas is comparable to QH and RMP plasmas, the absolute confinement of Neg-D is lower, owing to low elongation and low p_ped achieved thus far. Only the EDA-H, Neg-D, and L-mode scenarios have approached divertor-compatible high separatrix density conditions, with Neg-D preserving the highest performance owing to its compatibility with both high power and density.

description: We survey multi-label ranking tasks, specifically multi-label classification and label ranking classification. We highlight the unique challenges, and re-categorize the methods, as they no longer fit into the traditional categories of transformation and adaptation. We survey developments in the last demi-decade, with a special focus on state-of-the-art methods in deep learning multi-label mining, extreme multi-label classification and label ranking.

Exploring the microfluidic organ-on-chip platform for aerosol exposure study

Publisher: name: University of British Columbia

description: The microfluidic organ-on-chip platform exhibits promise for helping bridge the in vitro-in vivo gap through incorporating key elements of the in vivo microenvironment absent in traditional cell culture models. A prime example of such an element is fluid flow; tissues and their constituent cells are sensitive to a myriad of environmental stimuli, one of which is the mechanical forces that arise from wall shear stress exerted by these fluids. The work reported in the following thesis is focused on the small airways of the human lung and, particularly, how a microfluidic model of this physiology can be used in the study of aerosol exposure. Beginning with more traditional and well-established methods for the study of aerosol exposure in vitro, an aerosol generation apparatus was designed and employed to extract a panel of aerosols into solution for the assessment of cytotoxicity induced upon exposure in an airway epithelial cell line. A PDMS-based microfluidic small-airway-on-chip was, then, designed based on models reported in literature with optimizations included to balance physiological mimicry with established in vitro culture yields. A recirculating flow regime was developed, which enabled the application of wall-shear-stresses in ranges experienced by airway epithelia in vivo while minimizing consumption of reagents and maintaining the presence of excreted factors and chemokines. The microfluidic design and operating protocols were validated using both functional assays (permeability, inflammatory mediator release) and morphological features (F-actin localization). The small-airway-on-chip was, then, deployed in a novel experiment comprising the exposure of airway epithelium to aerosol generated from burnt wood at a dynamic ALI. Finally, an emerging method for characterization was explored: future applications of the silicon photonics platform to potential sensing and detection of biomolecules secreted by cells residing in organs-on-chip. Proof of concept experiments demonstrating the detection of recombinant interleukin 8 in buffer at natively expressed concentrations in vitro were performed.

description: Excerpts from the report: U.S. agricultural exports to all world areas totaled a record $4,946 million in fiscal 1960-61, compared with $4,527 million in 1959-60 and the previous record of $4,724 million in 1956-57. The largest gain in 1960-61 was in exports to Asia, which advanced to $1,511 million from $1,220 million a year earlier. Shipments to Europe expanded 7 percent to $2,275 million from $2,127 million. Canadian purchases (most important in North America) were 11 percent larger and totaled $455 million, though this total includes intransit grain and soybean shipments enroute to Western Europe. Shipments to Africa advanced 20 percent to $221 million. Exports to Oceania were up 8 percent to $42 million. Latin American purchases declined by 19 percent to $442 million from the 1959-60 total of $527 million. The rise in foreign demand for U.S. farm products during recent years has been due largely to the continued expansion of economic activity in the industrialized countries of Western Europe and Japan. Purchasing power as reflected in gold and dollar holdings of many U.S. trading partners stood at record levels and made possible the gradual removal of trade barriers against U.S. farm products. Institutional factors in the Free World also had a stimulating effect on the increase in exports in this period. Examples of these were the creation of the newly independent countries of Africa and Asia; large-scale U.S. economic aid programs in the developing countries; and the General Agreement on Tariffs and Trade.

description: We study the interplay between a soft muon Yukawa coupling generated radiatively with the trilinear A-terms of the minimal supersymmetric standard model (MSSM) and the anomalous magnetic moment of the muon. In the absence of a tree-level muon Yukawa coupling the lightest smuon mass is predicted to be in the range between 750 GeV and 2700 GeV at 2 sigma, if the bino mass M_1 is below 1 TeV. Therefore, a detection of a smuon (in conjunction with a sub-TeV bino) at the LHC would directly imply a non-zero muon Yukawa coupling in the MSSM superpotential. Inclusion of slepton flavor mixing could in principle lower the mass of one smuon-like slepton below 750 GeV. However, the experimental bounds on radiative lepton decays instead strengthen the lower mass bound, with larger effects for smaller M_1, We also extend the analysis to the electron case and find that a light selectron close to the current experimental search limit may prove the MSSM electron Yukawa coupling to be non-zero.

description: We perform a numerical simulation of the classical evolution of the plane-wave matrix model with semiclassical initial conditions. Some of these initial conditions thermalize and are dual to a black hole forming from the collision of D-branes in the plane wave geometry. In particular, we consider a large fuzzy sphere (a D2-brane) plus a single eigenvalue (a D0-particle) going exactly through the center of the fuzzy sphere and aimed to intersect it. Including quantum fluctuations of the off-diagonal modes in the initial conditions, with sufficient kinetic energy the configuration collapses to a small size. We also find evidence for fast thermalization: rapidly decaying autocorrelation functions at late times with respect to the natural time scale of the system.

description: We resolve an existing question concerning the location of the mobility edge for operators with a hopping term and a random potential on the Bethe lattice. The model has been among the earliest studied for Anderson localization, and it continues to attract attention because of analogies which have been suggested with localization issues for many particle systems. We find that extended states appear through disorder enabled resonances well beyond the energy band of the operator's hopping term. For weak disorder this includes a Lifshits tail regime of very low density of states.

description: Given a generically finite local extension of valuation rings $V \subset W$, the question of whether $W$ is the localization of a finitely generated $V$-algebra is significant for approaches to the problem of local uniformization of valuations using ramification theory. Hagen Knaf proposed a characterization of when $W$ is essentially of finite type over $V$ in terms of classical invariants of the extension of associated valuations. Knaf's conjecture has been verified in important special cases by Cutkosky and Novacoski using local uniformization of Abhyankar valuations and resolution of singularities of excellent surfaces in arbitrary characteristic, and by Cutkosky for valuation rings of function fields of characteristic $0$ using embedded resolution of singularities. In this paper we prove Knaf's conjecture in full generality.
