description: Anomalous hysteresis loops of ferrimagnetic amorphous alloys in high magnetic field and in the vicinity of the compensation temperature have so far been explained by sample inhomogeneities. We obtain H-T magnetic phase diagram for ferrimagnetic GdFeCo alloy using a two-sublattice model in the paramagnetic rare-earth ion approximation and taking into account rare-earth (Gd) magnetic anisotropy. It is shown that if the magnetic anisotropy of the $f$-sublattice is larger than that of the $d$-sublattice, the tricritical point can be at higher temperature than the compensation point. The obtained phase diagram explains the observed anomalous hysteresis loops as a result of high-field magnetic phase transition, the order of which changes with temperature. It also implies that in the vicinity of the magnetic compensation point the shape of magnetic hysteresis loop is strongly temperature dependent.

Canonical Metrics in Sasakian Geometry

description: The aim of this thesis is to study the existence problem for canonical Sasakian metrics, primarily Sasaki-Einstein metrics.  We are interested in providing both necessary conditions, as well as sufficient conditions for the existence of such metrics.
      We establish several sufficient conditions for the existence of Sasaki-Einstein metrics by studying the Sasaki-Ricci flow.  In the process, we extend some fundamental results from the study of the Kahler-Ricci flow to the Sasakian setting.  This includes finding Sasakian analogues of Perelman's energy and entropy functionals which are monotonic along the Sasaki-Ricci flow.  Using these functionals we extend Perelman's deep estimates for the Kahler-Ricci flow to the Sasaki-Ricci flow.  Namely, we prove uniform scalar curvature, diameter and non-collapsing estimates along the Sasaki-Ricci flow.  We show that these estimates imply a uniform transverse Sobolev inequality.  Furthermore, we introduce the sheaf of transverse foliate vector fields, and show that it has a natural, transverse complex structure.  We show that the convergence of the flow is intimately related to the space of global transversely holomorphic sections of this sheaf.
      We introduce an algebraic obstruction to the existence of constant scalar curvature Sasakian metrics, extending the notion of K-stability for projective varieties.
      Finally, we show that, for regular Sasakian manifolds whose quotients are Kahler-Einstein Fano manifolds, the Sasaki-Ricci flow, or equivalently, the Kahler-Ricci flow, converges exponentially fast to a (transversely) Kahler-Einstein metric.

Shifted Schur Functions

Publisher: name: arXiv
Year: 1996
Subjects: subject: Quantum Algebra (math.QA)
subject: FOS: Mathematics

description: The classical algebra $Λ$ of symmetric functions has a remarkable deformation $Λ^*$, which we call the algebra of shifted symmetric functions. In the latter algebra, there is a distinguished basis formed by shifted Schur functions $s^*_μ$, where $μ$ ranges over the set of all partitions. The main significance of the shifted Schur functions is that they determine a natural basis in $Z(\frak{gl}(n))$, the center of the universal enveloping algebra $U(\frak{gl}(n))$, $n=1,2,\ldots$. The functions $s^*_μ$ are closely related to the factorial Schur functions introduced by Biedenharn and Louck and further studied by Macdonald and other authors. A part of our results about the functions $s^*_μ$ has natural classical analogues (combinatorial presentation, generating series, Jacobi--Trudi identity, Pieri formula). Other results are of different nature (connection with the binomial formula for characters of $GL(n)$, an explicit expression for the dimension of skew shapes $λ/μ$, Capelli--type identities, a characterization of the functions $s^*_μ$ by their vanishing properties, `coherence property', special symmetrization map $S(\frak{gl}(n))\to U(\frak{gl}(n))$. The main application that we have in mind is the asymptotic character theory for the unitary groups $U(n)$ and symmetric groups $S(n)$ as $n\to\infty$. The results of this paper were used in \cite{Ok1--3}.

description: We present the calculation of the Feynman path integral in real time for tunneling in quantum mechanics and field theory, including the first quantum corrections. For this purpose, we use the well-known fact that Euclidean saddle points in terms of real fields can be analytically continued to complex saddles of the action in Minkowski space. We also use Picard-Lefschetz theory in order to determine the middle-dimensional steepest-descent surface in the complex field space, constructed from Lefschetz thimbles, on which the path integral is to be performed. As an alternative to extracting the decay rate from the imaginary part of the ground-state energy of the false vacuum, we use the optical theorem in order to derive it from the real-time amplitude for forward scattering. While this amplitude may in principle be obtained by analytic continuation of its Euclidean counterpart, we work out in detail how it can be computed to one-loop order at the level of the path integral, i.e. evaluating the Gaußian integrals of fluctuations about the relevant complex saddle points. To that effect, we show how the eigenvalues and eigenfunctions on a thimble can be obtained by analytic continuation of the Euclidean eigensystem, and we determine the path-integral measure on thimbles. This way, using real-time methods, we recover the one-loop result by Callan and Coleman for the decay rate. We finally demonstrate our real-time methods explicitly, including the construction of the eigensystem of the complex saddle, on the archetypical example of tunneling in a quasi-degenerate quartic potential.

description: Identification and localization of sounds are both integral parts of computational auditory scene analysis. Although each can be solved separately, the goal of forming coherent auditory objects and achieving a comprehensive spatial scene understanding suggests pursuing a joint solution of the two problems. This work presents an approach that robustly binds localization with the detection of sound events in a binaural robotic system. Both tasks are joined through the use of spatial stream segregation which produces probabilistic time-frequency masks for individual sources attributable to separate locations, enabling segregated sound event detection operating on these streams. We use simulations of a comprehensive suite of test scenes with multiple co-occurring sound sources, and propose performance measures for systematic investigation of the impact of scene complexity on this segregated detection of sound types. Analyzing the effect of spatial scene arrangement, we show how a robot could facilitate high performance through optimal head rotation. Furthermore, we investigate the performance of segregated detection given possible localization error as well as error in the estimation of number of active sources. Our analysis demonstrates that the proposed approach is an effective method to obtain joint sound event location and type information under a wide range of conditions.

description: We report {\it quantitative} microwave Faraday rotation measurements conducted with a high-mobility two-dimensional electron gas (2DEG) in a GaAs/AlGaAs semiconductor heterostructure. In a magnetic field, the Hall effect and the Faraday effect arise from the action of Lorentz force on electrons in the 2DEG. As with the Hall effect, a classical Faraday effect is observed at low magnetic field as well as a quantized Faraday effect at high magnetic field. The high electron mobility of the 2DEG enables a giant single-pass Faraday rotation of $θ_F^{max} \simeq 45^\circ$ $(\simeq0.8$~rad) to be achieved at a modest magnetic field of $B \simeq 100$~mT. In the quantum regime, we find that the Faraday rotation $θ_F$ is quantized in units of $α^*= 2.80(4)α$, where $α\simeq 1/137$ is the fine structure constant. The enhancement in rotation quantum $α^* > α$ is attributed to electromagnetic confinement within a waveguide structure.

description: We investigate the computational hardness of spin-glass instances on a square lattice, generated via a recently introduced tunable and scalable approach for planting solutions. The method relies on partitioning the problem graph into edge-disjoint subgraphs, and planting frustrated, elementary subproblems that share a common local ground state, which guarantees that the ground state of the entire problem is known a priori. Using population annealing Monte Carlo, we compare the typical hardness of problem classes over a large region of the multi-dimensional tuning parameter space. Our results show that the problems have a wide range of tunable hardness. Moreover, we observe multiple transitions in the hardness phase space, which we further corroborate using simulated annealing and simulated quantum annealing. By investigating thermodynamic properties of these planted systems, we demonstrate that the harder samples undergo magnetic ordering transitions which are also ultimately responsible for the observed hardness transitions on changing the sample composition.

description: The increasing complexity of communication networks in size and density provides us enormous opportunities to exploit interaction among multiple nodes, thus enabling higher rate of data streams. On the flip side, however, this complexity comes with challenges in managing interference that multiple source-destination pairs in the network may cause to each other. In this dissertation, we make progress on how to exploit the opportunities, as well as how to overcome the challenges for various communication networks.
      In the first part, we focus on developing fundamental principles for communication network design, especially networks with multiple antenna transceivers, with an emphasis on (1) understanding the role of feedback and cooperation, and (2) developing interference management methods. In this part, we find that feedback and cooperation have promising roles in improving the capacity performance of several interference networks. We show that in stark contrast to the point-to-point case, a limited feedback can improve the capacity of interference-limited networks. In fact, the improvement can be unbounded. This result shows that feedback can have a potentially significant role to play in mitigating interference.
      Then, in part two we study several bidirectional networks. We study the bidirectional diamond network and show that for deterministic and some Gaussian models the capacity is doubled for full-duplex channel in comparison with one-way networks. In addition, we study the degrees of freedom of two-way four-unicast MIMO networks, and provide upper and lower bounds that are tight in several cases. We also study the impact of caching in relay nodes for these models. We find a number of cases that bidirectional links can double the degrees of freedom with the help of relay caching and/or multiple relay antennas.

description: Inspired by the theoretical power of rewards in the labor market, to improve educational outcomes, this paper tests if giving a non-financial reward along with a financial one can result in higher student ex-post outcomes than just a financial incentive. The underlying mechanism by which non-financial reward might work is explored as well. The argument is based on Benabou and Tirole (2002)’s model, that non-financial reward may affect teachers’ self-esteem and, with that, their effort, and thereby the student outcomes after the reward is given. This is accomplished by exploiting a discontinuity in the running variable used to assign the Teaching Excellence Award (AEP for its initials in Spanish). A Sharp Regression Discontinuity Design is used to identify the effect of AEP using data for more than 5,000 math and language teachers. The dataset includes the teaching evaluation score that AEP gives every year to their applicants, the corresponding standardized test score of more than 100,000 students, (SIMCE for its initials in Spanish), school characteristics, and information about motivation and self-perception that teachers self-report in a survey administrated by SIMCE along with the standardized test every year. The results show that rewarding teachers by giving a non-financial reward along with a financial one does not work in the intended way. I find a not statistically significant effect of giving a reward to teachers with outstanding teaching skills and pedagogical knowledge on student test scores, teaching practices, teacher’s self-confidence in a window of three years after the certification process. Lastly, there is no evidence of teacher-student or teacher-school sorting as an ex-post effect of obtaining the certification.

description: Recommender systems are personalized information access applications; they are ubiquitous in today's online environment, and effective at finding items that meet user needs and tastes. As the reach of recommender systems has extended, it has become apparent that the single-minded focus on the user common to academic research has obscured other important aspects of recommendation outcomes. Properties such as fairness, balance, profitability, and reciprocity are not captured by typical metrics for recommender system evaluation. The concept of multistakeholder recommendation has emerged as a unifying framework for describing and understanding recommendation settings where the end user is not the sole focus. This article describes the origins of multistakeholder recommendation, and the landscape of system designs. It provides illustrative examples of current research, as well as outlining open questions and research directions for the field.

This asymmetry is used to explain puzzles in recent high source-drain transport experiments.

description: Increasing urbanisation of coastal areas is placing unprecedented pressure on estuarine environments. Impacts associated with urbanisation can alter the health of estuarine ecosystems, reducing their capacity to provide valuable ecosystem services. In order protect these environments, relationships between estuarine health and urbanisation should be understood and applied to sustainable urban planning in coastal areas. Responses measured in estuarine biota offer much potential for providing pragmatic and sensitive means for the detection of urban impacts in estuaries. I assessed the responses of estuarine biota to increasing levels of urbanisation in the rapidly developing coastal region of southeast Queensland, Australia. I measured a suite of biotic indicators, namely: the [delta-N-15] of mangroves and crabs as a tracer for urban N sources, sediment chlorophyll a concentration (Chl a) as an estimate of the biomass of microphytobenthos (MPB), and a condition index in crabs, measured as the hepatosomatic index (HI). Urbanisation was estimated as the percentage of catchment covered by impervious surfaces (impervious cover, IC). Increases in impervious surfaces such as roads, footpaths and car parks are closely linked to urbanisation. These surfaces concentrate and convey pollutants generated from urban activities into coastal waterways and estuaries, thus making IC a useful indicator of urban impact.

description: We calculate dc conductivities of ballistic graphene undulated by an overlying moving unidirectional electrical superlattice (SL) potential whose SL velocity is smaller than the electron velocity. We obtain no dependence of the conductivity on the velocity along the direction of the superlattice wave vector. In the orthogonal direction however, the dependence is strong on the velocity especially at voltages where a new Dirac point emerges for zero velocity. It is shown that the infinite graphene system can serve as an ideal motion detector at potentials where the first new Dirac point emerges. There the conductivity is zero at vanishing SL velocities and jumps to infinity when the SL starts moving. For finite systems at voltages where the number of new Dirac points is of the order of the ratio of the electron velocity by the SL velocity, the modifications to the conductivity of a moving SL is at least of similar magnitude as the conductivity of the stagnant SL.

description: Der Artikel problematisiert die Übertragbarkeit des westlichen Governance- Konzepts auf Räume außerhalb der OECD-Welt. Ziel ist es, einen Forschungsansatz zu entwickeln, der diesen Räumen angemessenen ist. Zu diesem Zweck werden zunächst eurozentrische Prämissen im Governance-Konzept sichtbar gemacht. Hier geht es um die zentrale Dichotomie zwischen staatlichen und gesellschaftlichen Akteuren. Die Allgegenwart dieser Unterscheidung wird anschließend mit Hilfe der (de-)konstruktivistischen Erkenntnistheorien Foucaults, Luhmanns und Derridas erklärt. Ausgehend von einem zwar unumgänglichen, aber in seinem Ausmaß variablen Eurozentrismus skizziert die Autorin schließlich eine äquivalenzfunktionalistische Governance-Forschung, die nach der Art und Weise einer Leistung, nach dem „Wie“ und dem „Wer“, fragt. So werden europäische Dichotomien in Bezug auf die Akteure und die Handlungsmodi von Governance vermieden.

description: We present a computational framework for modeling geomaterials undergoing failure in the brittle and ductile regimes. This computational framework introduces anisotropic gradient regularization to replicate a wide spectrum of size-dependent anisotropic constitutive responses exhibited in layered and sedimentary rock. Relevant subsurface applications include oil/gas wellbore completions, caprock evaluation for carbon sequestration in saline aquifers, and geothermal energy recovery. Considered failure modes are mixed-mode fracture, shear band formation due to plastic strain localization, and rate-dependent frictional slip along the propagated fracture's rock surface, subsequent to fracture closure. Our nonlocal modeling framework extends the state-of-the-art gradient-enhanced plasticity and damage mechanics for frictional materials with a special treatment that injects bias for the regularization for different orientations. A novel contribution is that the formulations not only contains a regularization, but that the regularization also provides a method to introduce size-dependent anisotropies. Consequently, this treatment provides a new means to create non-associative flow via a variational framework while introducing different anisotropic responses for specimens of different sizes (introduced in Chapter 1). These anisotropic regularization modeling techniques are then applied to three classes of common geomechanics problems: critical state plasticity of clay and shale rock (Chapter 2), brittle fracture of rock (Chapter 3), and the plastic slip of interfaces and cracks (Chapter 4). This combination, of established rock physics, local anisotropy, and size-dependent anisotropy enfranchised with diffusive regularization, is investigated. For instance, experimentation on uniaxially compressed specimens failing in the brittle regime reveals a repeatable typology of wing- and coalescent-crack patterns, broadly taken to indicate a mixed-mode fracture phenomenon particular to rock-like materials. In the ductile regime, biaxially compressed shale rock displays orientation-dependence of the plastic deformation difficult to capture merely by attributing anisotropy to the elastic response, with localization at or near the critical state. We numerically capture both these phenomena. Verification and/or validation is provided for proposed constitutive relations.

description: This dissertation begins with a review of Calabi-Yau manifolds and their moduli spaces, flux compactification largely tailored to the case of type IIb supergravity, and Coleman-De Luccia vacuum decay. The three chapters that follow present the results of novel research conducted as a graduate student.
      Our first project is concerned with bubble collisions in single scalar field theories with multiple vacua. Lorentz boosted solitons traveling in one spatial dimension are used as a proxy to the colliding 3-dimensional spherical bubble walls. Recent work found that at sufficiently high impact velocities collisions between such bubble vacua are governed by "free passage" dynamics in which field interactions can be ignored during the collision, providing a systematic process for populating local minima without quantum nucleation.
      We focus on the time period that follows the bubble collision and provide evidence that, for certain potentials, interactions can drive significant deviations from the free passage bubble profile, thwarting the production of a new patch with different field value. However, for simple polynomial potentials a fine-tuning of vacuum locations is required to reverse the free passage kick enough that the field in the collision region returns to the original bubble vacuum. Hence we deem classical transitions mediated by free passage robust.
      Our second project continues with soliton collisions in the limit of relativistic impact velocity, but  with the new feature of  nontrivial  field space curvature. We establish a simple geometrical interpretation of such collisions in terms of a double family of field profiles whose tangent vector fields stand in mutual parallel transport. This provides a generalization of the well-known limit in flat field space (free passage). We investigate the limits of this approximation and illustrate our analytical results with numerical simulations.
      In our third and final project we investigate the distribution of field theories that arise from the low energy limit of flux vacua built on type IIb string theory compactified on the mirror quintic. For a large collection of these models, we numerically determine the distribution of Taylor coefficients in a polynomial expansion of each model's scalar potential to fourth order. We provide an analytic explanation of the proncounced hierarchies exhibited by the random sample of masses and couplings generated numerically. The analytic argument is based on the structure of masses in no scale supergravity and the divergence of the Yukawa coupling at the conifold point in the moduli space of the mirror quintic. Our results cast the superpotential vev as a random element whose capacity to cloud structure vanishes as the conifold is approached.

description: The phase transition in a model for vortex lines in high temperature superconductors with columnar defects, i.e., linearly correlated quenched random disorder, is studied with finite size scaling and Monte Carlo simulations. Previous studies of critical properties have mainly focused on the limit of strongly screened vortex line interactions. Here the opposite limit of weak screening is considered. The simulation results provide evidence for a new universality class, with new critical exponents that differ from the case of strong screening of the vortex interaction. In particular, scaling is anisotropic and characterized by a nontrivial value of the anisotropy exponent $ζ=ν_\parallel/ν_\perp$. The exponents we find, $ζ= 1.25 \pm 0.1, ν_\perp=1.0 \pm 0.1, z = 1.95 \pm 0.1$, are similar to certain experimental results on YBCO.

description: Drone racing is becoming a popular e-sport all over the world, and beating the best human drone race pilots has quickly become a new major challenge for artificial intelligence and robotics. In this paper, we propose a strategy for autonomous drone racing which is computationally more efficient than navigation methods like visual inertial odometry and simultaneous localization and mapping. This fast light-weight vision-based navigation algorithm estimates the position of the drone by fusing race gate detections with model dynamics predictions. Theoretical analysis and simulation results show the clear advantage compared to Kalman filtering when dealing with the relatively low frequency visual updates and occasional large outliers that occur in fast drone racing. Flight tests are performed on a tiny racing quadrotor named "Trashcan", which was equipped with a Jevois smart-camera for a total of 72g. The test track consists of 3 laps around a 4-gate racing track. The gates spaced 4 meters apart and can be displaced from their supposed position. An average speed of 2m/s is achieved while the maximum speed is 2.6m/s. To the best of our knowledge, this flying platform is the smallest autonomous racing drone in the world and is 6 times lighter than the existing lightest autonomous racing drone setup (420g), while still being one of the fastest autonomous racing drones in the world.
title: How Far Can You Stretch a Note?: Developing an Approach to the Study of Metaphor in the Language of Music Instruction
Creators: name: Wolfe, Jocelyn Kay
Publisher: name: Griffith University

Subjects: subject: Musical meaning
subject: Musical expression
subject: Metaphor in music education
subject: Applied linguistics

description: Across disciplines, metaphor allows teachers to communicate with learners to visualise abstract concepts, clarify complex concepts, and label difficult concepts. This role potentially intensifies venturing into the intangible realms of musical meaning and expression. While it is clear that metaphor is used extensively in music education, little research to date has examined how metaphor is applied in music instruction at advanced levels. In such levels, extramusical referents explain not just the structure of music, but the expressive performance features used to make one interpretation more meaningful to listeners than another. This study explores the sound world of music teachers through the lens of the language they use, building on increasing evidence in applied linguistics and cognitive linguistics regarding the value of metaphor in educational settings. Using the tools of applied linguistics, it brings a collection of real-life data to a research territory where empirical evidence meets philosophical debate to account for metaphor in language and underlying thought. From the study, it is clear that metaphor is highly conventionalised in teacher talk during advanced music instruction. There are hitherto undetected structures and patterns in the use of metaphor, in the vehicles and specific topics referred to in its linguistic expression, as well as in source to target domain correlations. On the surface, there is an apparent diversity in the way teachers describe musical sound, while on a deeper level, a striking systematicity is evident. This allows for developing an investigative approach which enables new insights into the nature and function of metaphorical language in advanced music instruction.

description: In this paper the Diffusion Monte Carlo (DMC) method is applied to the confined hydrogen atom with different confinement geometries. This approach is validated using the much studied spherical and cylindrical confinements and then applied to cubical and squared ones, for which data are not available, as new applications of the method relevant to solid state physics. The energy eigenvalues of the ground state and one low-lying excited state are reported as a function of the characteristic confinement length.

description: A new discretisation of a doubled, i.e. BF, version of the pure abelian Chern-Simons theory is presented. It reproduces the continuum expressions for the topological quantities of interest in the theory, namely the partition function and correlation function of Wilson loops. Similarities with free spinor field theory are discussed which are of interest in connection with lattice fermion doubling.

Missing Red Supergiants and Carbon Burning

description: Recent studies on direct imaging of Type II core-collapse supernova progenitors indicate a possible threshold around $M_{\rm ZAMS}\sim 16-20$ M$_\odot$, where red supergiants with larger birth masses do not appear to result in supernova explosions and instead implode directly into a black hole. In this study we argue that it is not a coincidence that this threshold closely matches the critical transition of central Carbon burning in massive stars from the convective to radiative regime. In lighter stars, Carbon burns convectively in the center and result in compact final presupernova cores that are likely to result in explosions, while in heavier stars after the transition, it burns as a radiative flame and the stellar cores become significantly harder to explode. Using the KEPLER code we demonstrate the sensitivity of this transition to the rate of $^{12}$C$(α,γ)^{16}$O reaction and the overshoot mixing efficiency, and we argue that the upper mass limit of exploding red supergiants could be employed to constrain uncertain input physics of massive stellar evolution calculations. The initial mass corresponding to the central Carbon burning transition range from 14 to 26 M$_\odot$ in recently published models from various groups and codes, and only a few are in agreement with the estimates inferred from direct imaging studies.

description: The World Health Organization (2020a) labels childhood obesity as ‘one of the most serious public health challenges of the 21st Century’ (para. 1). Schools are avenues for obesity intervention through food literacy education, the delivery of which occurs in Health and Physical Education and in Design and Technologies (Home Economics) in the Australian Curriculum (Australian Institute of Health & Welfare, 2017; Ronto et al., 2017a). In this study, home economics as the subject for the delivery for food literacy education is the focus. An exploratory mixed methods case study was engaged using an online survey instrument for data collection during February-March 2021. The research questions explored Australian curriculum and school-based influences and constraints on years 7-10 Queensland secondary school food literacy programs, how Home Economics teachers, who are members of the Home Economics Institute of Australia (Queensland), currently deliver food literacy through the Australian Curriculum, and the changes in the Australian Curriculum, and school-based support, they require to deliver effective holistic food literacy programs. SPSS and Leximancer were used to analyse quantitative and qualitative data respectively, followed by data convergence to address the research questions. Key findings reveal that 80% of respondents agreed that the current Design and Technologies curriculum needs to be changed, furthermore 61% agreed that school-based change was required to support effective, holistic food literacy education. Curriculum mandated practical food education and transition of nutrition into home economics subjects were core themes in the responses. This study contributes to the growing body of research signifying the value of home economics to deliver school-based food literacy education. It contributes to this evidence base by exploring in depth the influences and constraints experienced by home economics teachers to undertake this work. Given the role of home economics educators as key to addressing the childhood obesity crisis, this study reveals the challenges that serve as impediments to this crucial work.
