Landscape assessment

description: This research follows the topic of art and the everyday, and focuses on how our experience of the everyday is a significant area of educational inquiry. This study investigates the potential of walking as an interactive method of art education that relates to the way we learn from our everyday environment, and is connected to the field of visual culture art education, and the aesthetics of everyday life. By taking participants on an art walk, I can observe how they engage with their everyday environment directly, and examine whether walking can promote visual and aesthetic awareness towards their ordinary surroundings. A total of eight participants will be studied during the walk; participants represent a mixed variation of age and gender, with and without backgrounds in art, and will participate in a walking interview followed by a sit-down interview.

Art and Power in the Reign of Catherine the Great: The State Portraits
Creators: McBurney, Erin

Subjects: Portrait painting, Russian
Power (Social sciences) in art

History

description: This dissertation examines the relationship between art and power in the reign of Catherine II of Russia (1762-1796). It considers Catherine's state portraits as historical texts that revealed symbolic manifestations of autocratic power, underscoring the close relationship between aesthetics and politics during the reign of Russia's longest serving female ruler. The Russian empress actively exploited the portrait medium in order to transcend the limitations of her gender, assert legitimacy and display herself as an exemplar of absolute monarchy. The resulting symbolic representation was protean and adaptive, and it provided Catherine with a means to negotiate the anomaly of female rule and the ambiguity of her Petrine inheritance. In the reign of Catherine the Great, the state portraits functioned as an alternate form of political discourse.

description: We consider a $D$-dimensional Einstein-Gauss-Bonnet model with a cosmological term $Λ$ and two non-zero constants: $α_1$ and $α_2$. We restrict the metrics to be diagonal ones and study a class of solutions with exponential time dependence of three scale factors, governed by three non-coinciding Hubble-like parameters: $H \neq 0$, $h_1$ and $h_2$, obeying $m H + k_1 h_1 + k_2 h_2 \neq 0$ and corresponding to factor spaces of dimensions $m > 1$, $k_1 > 1$ and $k_2 > 1$, respectively ($D = 1 + m + k_1 + k_2$). We analyse two cases: i) $m < k_1 < k_2$ and ii) $1< k_1 = k_2 = k$, $k \neq m$. We show that in both cases the solutions exist if $α= α_2 / α_1 > 0$ and $αΛ> 0$ satisfies certain restrictions, e.g. upper and lower bounds. In case ii) explicit relations for exact solutions are found. In both cases the subclasses of stable and non-stable solutions are singled out. For $m > 3$ the case i) contains a subclass of solutions describing an exponential expansion of $3$-dimensional subspace with Hubble parameter $H > 0$ and zero variation of the effective gravitational constant $G$. The case $H = 0$ is also considered.

description: By intentionally underestimating the rate of convergence of exact-diagonalization values for the mass or energy gaps of finite systems, we form families of sequences of gap estimates. The gap estimates cross zero with generically nonzero linear terms in their Taylor expansions, so that $ν= 1$ for each member of these sequences of estimates. Thus, the Coherent Anomaly Method can be used to determine $ν$. Our freedom in deciding exactly how to underestimate the convergence allows us to choose the sequence that displays the clearest coherent anomaly. We demonstrate this approach on the two-dimensional ferromagnetic Ising model, for which $ν= 1$. We also use it on the three-dimensional ferromagnetic Ising model, finding $ν\approx 0.629$, in good agreement with other estimates.

Appearance of Fermion Condensation Quantum Phase Transition in Different Fermi Liquids

description: We show that the quasiparticle effective mass $M^*$ diverges as a function of the system's density $x$, $M^*\propto 1/(x-x_{FC})$, when a system approaches the critical point $x_{FC}$ at which the fermion condensation quantum phase transition (FCQPT) occurs. Such behavior is of general form and takes place in both three dimensional systems and two dimensional ones. We demonstrate that a system which has undergone FCQPT and lies close to the critical point $x_{FC}$ can be driven back into the normal Fermi liquid by applying a small magnetic field $B$. As the field $B$ is reduced, the system is tuned back to the critical point and the effective mass diverges as $M^*\propto 1/\sqrt{B-B_{FC}}$ where $B_{FC}$ is the maximum field at which FCQPT takes place. We demonstrate the constancy of the Kadowaki-Woods ratio when approaching the critical point at the fields $B>B_{FC}$. Analyzing recent experimental data on the effective mass behavior in a strongly correlated two dimensional fluid $^3$He, in metallic two dimensional electron systems and in heavy-fermion systems, we show that the observed behavior is in agreement with our consideration. As a result, we may conclude that FCQPT can be conceived of as a universal cause of the strongly correlated regime in different Fermi liquids.

Asymptotic and Factorization Analysis for Inverse Shape Problems in Tomography and Scattering Theory

subject: Partial differential equations

description: Developing non-invasive and non-destructive testing in complex media continues to be a rich field of study (see e.g.[22, 28, 36, 76, 89] ). These types of tests have applications in medical imaging, geophysical exploration, and engineering where one would like to detect an interior region or estimate a model parameter. With the current rapid development of this enabling technology, there is a growing demand for new mathematical theory and computational algorithms for inverse problems in partial differential equations. Here the physical models are given by a boundary value problem stemming from Electrical Impedance Tomography (EIT), Diffuse Optical Tomography (DOT), as well as acoustic scattering problems. Important mathematical questions arise regarding existence, uniqueness, and continuity with respect to measured surface data. Rather than determining the solution of a given boundary value problem, we are concerned with using surface data in order to develop and implement numerical algorithms to recover unknown subregions within a known domain. A unifying theme of this thesis is to develop Qualitative Methods to solve inverse shape problems using measured surface data. These methods require very few a priori assumptions on the regions of interest, boundary conditions, and model parameter estimation. The counterpart to qualitative methods, iterative methods, typically require a priori information that may not be readily available and can be more computationally expensive. Qualitative Methods usually require more data.This thesis expands the library of Qualitative Methods for elliptic problems coming from tomography and scattering theory. We consider inverse shape problems where our goal is to recover extended and small volume regions. For extended regions, we consider applying a modified version of the well-known Factorization Method [73]. Whereas for the small volume regions, we develop a Multiple Signal Classification (MUSIC)-type algorithm (see for e.g. [3, 5]). In all of our problems, we derive an imaging functional that will effectively recover the region of interest. The results of this thesis form part of the theoretical forefront of physical applications. Furthermore, it extends the mathematical theory at the intersection of mathematics, physics and engineering. Lastly, it also advances knowledge and understanding of imaging techniques for non-invasive and non-destructive testing.

description: The main result of this paper is the proof of the "transversal part" of the homological mirror symmetry conjecture for an elliptic curve which states an equivalence of two $A_{\infty}$-structures on the category of vector bundles on an elliptic curves. The proof is based on the study of $A_{\infty}$-structures on the category of line bundles over an elliptic curve satisfying some natural restrictions (in particular, $m_1$ should be zero, $m_2$ should coincide with the usual composition). The key observation is that such a structure is uniquely determined up to homotopy by certain triple products.

description: Learning product representations that reflect complementary relationship plays a central role in e-commerce recommender system. In the absence of the product relationships graph, which existing methods rely on, there is a need to detect the complementary relationships directly from noisy and sparse customer purchase activities. Furthermore, unlike simple relationships such as similarity, complementariness is asymmetric and non-transitive. Standard usage of representation learning emphasizes on only one set of embedding, which is problematic for modelling such properties of complementariness. We propose using knowledge-aware learning with dual product embedding to solve the above challenges. We encode contextual knowledge into product representation by multi-task learning, to alleviate the sparsity issue. By explicitly modelling with user bias terms, we separate the noise of customer-specific preferences from the complementariness. Furthermore, we adopt the dual embedding framework to capture the intrinsic properties of complementariness and provide geometric interpretation motivated by the classic separating hyperplane theory. Finally, we propose a Bayesian network structure that unifies all the components, which also concludes several popular models as special cases. The proposed method compares favourably to state-of-art methods, in downstream classification and recommendation tasks. We also develop an implementation that scales efficiently to a dataset with millions of items and customers.

Using Wilson's renormalization group we analyze the frequency and temperature dependence of the impurity spectral density for impurities in small systems that are either isolated or in contact with a reservoir. We have performed a detailed analysis of the structure of the impurity spectral density for energies around the Fermi energy for different Fermi energies relative to the intrinsic structure of the local density of states. We show how the electron confinement energy scales introduce new features in the frequency and temperature dependence of the impurity spectral properties.

Electric bias-controlled switching of magnetization of ferrimagnetically coupled Mn delta-layers in a GaAs-AlGaAs quantum well

description: We suggest a model of synthetic ferrimagnetic semiconductor structure based on GaAs-AlGaAs quantum well doped by two Mn delta-layers. The coupling between the delta-layers is mediated by extra holes, and can be switched between ferro- and antiferromagnetic one by gating the structure. A proper choice of Mn concentrations in the delta-layers and of local degree of disorder enables fabrication of a ferrimagnetic structure supporting ultrafast switching of magnetization by short pulses of electric bias without an external magnetic field. The switching mechanism in the structure relies on kinetic spin exchange between the two delta-layers which is mediated by exchange scattering of electric-pulse heated holes by magnetic ions within the layers. Owing to specific interplay between characteristics of the exchange scattering, spin decay times, and the heat withdraw in the suggested synthetic ferrimagnetic semiconductor, the necessary parameters of electric-bias pulse are within the technologically accessible range, and do not contradict typical thermal kinetics of semiconductor structures.

description: We consider the problem of localizing spectrally overlapped sources in cognitive radio networks. A new weighted centroid localization algorithm (WCL) called Cyclic WCL is proposed, which exploits the cyclostationary feature of the target signal to estimate its location coordinates. In order to analyze the algorithm in terms of root-mean-square error (RMSE), we model the location estimates as the ratios of quadratic forms in a Gaussian random vector. With analysis and simulation, we show the impact of the interferer location and its modulation scheme on the RMSE. We also study the RMSE performance of the algorithm for different power levels of the target and the interference. Further, the comparison between Cyclic WCL and WCL w/o cyclostationarity is presented. It is observed that the Cyclic WCL provides significant performance gain over WCL.

description: Angiotensin (Ang) II mediates pathophysiologial changes in the kidney. Ang-(1–7) by interacting with the G protein-coupled receptor Mas may also have important biological activities. In this study, renal deficiency for Mas diminished renal damage in models of renal insufficiency as unilateral ureteral obstruction and ischemia/reperfusion injury while the infusion of Ang-(1–7) to wild-type mice pronounced the pathological outcome by aggravating the inflammatory response. Mas deficiency inhibited NF-κB activation and thus the elevation of inflammation-stimulating cytokines, while Ang-(1–7) infusion had proinflammatory properties in experimental models of renal failure as well as under basal conditions. The Ang-(1–7)-mediated NF-κB activation was Mas dependent but did not involve Ang II receptors. Therefore, the blockade of the NF-κB-activating properties of the receptor Mas could be a new strategy in the therapy of failing kidney.

For a given Complex projective threefold X of general type, suppose the plurigenus p_k(X)\ge 2, Kollar proved that the (11k+5)-canonical map is birational. Here we show that either the (7k+3)-canonical map or the (7k+5)-canonical map is birational and that the m-canonical map is stably birational for m\ge 13k+6. If P_k(X)\ge 3, then the m-canonical map is stably birational for m\ge 10k+8. In particular, the 12-canonical map is birational when p_g(X)\ge 2 and the 11-canonical map is birational when p_g(X)\ge 3.

description: We compute dispersion relations of non-hydrodynamic and hydrodynamic modes in a non-relativistic strongly coupled two-dimensional quantum field theory. This is achieved by numerically computing quasinormal modes (QNMs) of a particular analytically known black brane solution to 3+1-dimensional Hořava Gravity. Hořava Gravity is distinguished from Einstein Gravity by the presence of a scalar field, termed the khronon, defining a preferred time-foliation. Surprisingly, for this black brane solution, the khronon fluctuation numerically decouples from all others, having its own set of purely imaginary eigenfrequencies, for which we provide an analytic expression. All other Hořava Gravity QNMs are expressed analytically in terms of QNMs of Einstein Gravity, in units involving the khronon coupling constants and various horizons. Our numerical computation reproduces the analytically known momentum diffusion mode, and extends the analytic expression for the sound modes to a wide range of khronon coupling values. In the eikonal limit (large momentum limit), the analytically known dispersion of QNM frequencies with the momentum is reproduced by our numerics. We provide a parametrization of all QNM frequencies to fourth order in the momentum. We demonstrate perturbative stability in a wide range of coupling constants and momenta.

description: Contemporary artist residencies are institutions or programs that enable artists to develop their practice beyond the confines of their typical work setting. Increasingly, they are also a means to access significant material, interpersonal, and professional resources, and a medium through which to engage with local communities. In response to these developments, the present interview-based study aims to understand how artists develop within a community context by investigating the work and experiences of eight artists who have participated in community-based residencies across—and sometimes beyond—the United States. By collecting each artist’s narrative and supplementing it with documents, images, and auto-reflections of their artwork, the study investigates the complex network of characteristics that help facilitate the creative process. Furthermore, by canvassing research from fields like social psychology, business management, and arts education, it explores the relations of educational reciprocity that emerge between artists and residency communities. This study suggests that the complex physical and interpersonal dynamics of each residency environment contributed in distinctive ways to the artists’ development. It also notes that each unique residency program provided support for the use of new materials, the exploration of new practices, and the investigation of new content. The residency characteristics that were most conducive to creative growth included (1) difference from one’s typical working environment; (2) access to new (and sometimes unconventional) materials, tools, and facilities; (3) social opportunities such as shared meals and public forums to cultivate relationships with residency cohorts; and (4) ample time (usually 1–2 months) and space (access to both private and public studios) to settle into the residency environment, explore one’s artistic practice (and the practice of other resident artists), and foster relationships among cohorts, staff members, and community visitors. Ultimately, this study argues that artist residencies can contribute to the field of non-formal art education by serving as a relational framework for artists and their residency communities.

description: The dependency between the Gaussianity of the input distribution for the additive white Gaussian noise (AWGN) channel and the gap-to-capacity is discussed. We show that a set of particular approximations to the Maxwell-Boltzmann (MB) distribution virtually closes most of the shaping gap. We relate these symbol-level distributions to bit-level distributions, and demonstrate that they correspond to keeping some of the amplitude bit-levels uniform and independent of the others. Then we propose partial enumerative sphere shaping (P-ESS) to realize such distributions in the probabilistic amplitude shaping (PAS) framework. Simulations over the AWGN channel exhibit that shaping 2 amplitude bits of 16-ASK have almost the same performance as shaping 3 bits, which is 1.3 dB more power-efficient than uniform signaling at a rate of 3 bit/symbol. In this way, required storage and computational complexity of shaping are reduced by factors of 6 and 3, respectively.

description: We demonstrate that good superconductor/insulator/normal-metal tunnel junctions can be fabricated on as-grown superconducting MgB2 thin films. The as-grown films were prepared by coevaporation at low growth temperatures of around 280deg. The insulating barrier was formed by an Mg overlayer, which is subsequently oxidized in air. The tunneling spectra for Au/MgOx/MgB2 junctions showed a reproducible and well-defined superconducting gap (delta= ~ 2.5 meV). The resultant 2delta/ kBTc was significantly smaller than the predicted BCS value of 3.52.

Unsupervised frequency clustering algorithm for null space estimation in wideband spectrum sharing networks

description: In spectrum sharing networks, a base station (BS) needs to mitigate the interference to users associated with other coexisting network in the same band. The BS can achieve this by transmitting its downlink signal in the null space of channels to such users. However, under a wideband scenario, the BS needs to estimate null space matrices using the received signal from such non-cooperative users in each frequency bin where the users are active. To reduce the computational complexity of this operation, we propose a frequency clustering algorithm that exploits the channel correlations among adjacent frequency bins. The proposed algorithm forms clusters of frequency bins with correlated channel vectors without prior knowledge of the channels and obtains a single null space matrix for each cluster. We show that the number of matrices and the number of eigenvalue decompositions required to obtain the null space significantly reduce using the proposed clustering algorithm.

description: Despite recent advancements, modern kitchens, at best, have one or more isolated (non-communicating) “smart” devices. The vision of having a fully-fledged ambient kitchen where devices know what to do and when has yet to be realised. RiCoRecA, a novel schema for parsing cooking recipes into a workflow representation suitable for automation, is a step towards that direction. The schema requires a number of information extraction tasks, i.e., the
annotation of named entities, the identification of relations between them, coreference resolution as well as entity tracking. RiCoRecA differs from previously reported approaches in that it learns these different information extraction tasks using one joint model. We also provide a dataset containing annotations that follow this schema. Furthermore, we compared two transformer-based models for parsing recipes into workflows, namely, PEGASUS-X and LongT5. Our results demonstrate that PEGASUS-X surpassed LongT5 on all of the annotation tasks. Specifically, PEGASUS-X surpassed LongT5 by 39% in terms of F-Score when averaging the performance on all the tasks; it demonstrated almost human-like performance.
Toward a q-Deformed Standard Model

description: A gauge theory with an underlying SU_q(2) quantum group symmetry is introduced, and its properties examined. With suitable assumptions, this model is found to have many similarities with the usual SU(2)\times U(1) Standard Model, specifically, the existence of four generators and thus four gauge fields. However, the two classical symmetries are unified into one quantum symmetry, and therefore there is only a single coupling constant, rather than two. By incorporating a Higgs sector into the model, one obtains several explicit tree-level predictions in the undeformed limit, such as the Weinberg angle: $sin^2Θ_{W} = 3/11$. With the Z-boson mass m_Z and fine structure constant alpha as inputs, one can also obtain predictions for the weak coupling constant, the mass of the W, and the Higgs VEV. The breaking of the quantum invariance also results in a remaining undeformed U(1) gauge symmetry.

description: We prove strong completeness results for some modal logics with the universal modality, with respect to their topological semantics over 0-dimensional dense-in-themselves metric spaces. We also use failure of compactness to show that, for some languages and spaces, no standard modal deductive system is strongly complete.

description: Time-resolved Kerr microscopy is used to study the excitations of individual micron- scale ferromagnetic thin film elements in their remnant state. Thin (18 nm) square elements with edge dimensions between 1 and 10 $μ$m form closure domain structures with 90 degree Neel walls between domains. We identify two classes of excitations in these systems. The first corresponds to precession of the magnetization about the local demagnetizing field in each quadrant, while the second excitation is localized in the domain walls. Two modes are also identified in ferromagnetic disks with thicknesses of 60 nm and diameters from 2 $μ$m down to 500 nm. The equilibrium state of each disk is a vortex with a singularity at the center. As in the squares, the higher frequency mode is due to precession about the internal field, but in this case the lower frequency mode corresponds to gyrotropic motion of the entire vortex. These results demonstrate clearly the existence of well-defined excitations in inhomogeneously magnetized microstructures.

description: We provide several new $q$-congruences for truncated basic hypergeometric series with the base being an even power of $q$. Our results mainly concern congruences modulo the square or the cube of a cyclotomic polynomial and complement corresponding ones of an earlier paper containing $q$-congruences for truncated basic hypergeometric series with the base being an odd power of $q$. We also give a number of related conjectures including $q$-congruences modulo the fifth power of a cyclotomic polynomial and a congruence for a truncated ordinary hypergeometric series modulo the seventh power of a prime greater than 3.

description: Contrastive Linguistics (CL), Translation Studies (TS) and Machine Translation (MT) have common grounds: They all work at the crossroad where two or more languages meet. Despite their inherent relatedness, methodological exchange between the three disciplines is rare. This special issue touches upon areas where the three fields converge. It results directly from a workshop at the 2011 German Association for Language Technology and Computational Linguistics (GSCL) conference in Hamburg where researchers from the three fields presented and discussed their interdisciplinary work. While the studies contained in this volume draw from a wide variety of objectives and methods, and various areas of overlaps between CL, TS and MT are addressed, the volume is by no means exhaustive with regard to this topic. Further cross-fertilisation is not only desirable, but almost mandatory in order to tackle future tasks and endeavours, and this volume is committed to bringing these three fields even closer together.

description: We construct the equations of motion for the coupled dynamics of order parameter and concentration for the nematic phase of driven particles on a solid surface, and show that they imply (i) giant number fluctuations, with a standard deviation proportional to the mean and (ii) long-time tails $\sim t^{-d/2}$ in the autocorrelation of the particle velocities in $d$ dimensions despite the absence of a hydrodynamic velocity field. Our predictions can be tested in experiments on aggregates of amoeboid cells as well as on layers of agitated granular matter.

Artistic Patrimony and Cultural Politics in Early Seicento Venice

description: In the period following the Cinquecento Renaissance, contemporary seventeenth century Venetian artists were presented with two enormous challenges. The first was to attempt to reinterpret their visual tradition within a shifting political climate without declining into an overt stylistic retrospection. The second was to try and retain a semblance of the personification of state identity—those qualities that had been established and distinguished by Venetian art in the Cinquecento —and which were present in the visual patrimony of paintings and drawings. Carlo Ridolfi, art critic and author of Le maraviglie dell’Arte (1648) eloquently stated the problem in his biography of Giovanni Contarino, a student of Titian’s, when he praised the work of the Cinquecento masters as the epitome of artistic production to the extent that he says, “it is with reason that one could use as motto the two columns of Hercules with the words: “Ultra quid faciam?" it is in fact vain to pretend better examples, and rarer beautiful things could be made.” This dissertation considers two parallel issues at work: the stylistic legacy of Cinquecento Venetian masters and their importance in the work of their Seicento heirs, and the purposeful dissolution and sale of collections of work by those masters during the seventeenth century. The business activities of art dealers Marco Boschini (1602/5—1681), Paolo del Sera (1614—1672) and their associates are examined alongside their perceptions and criticisms of Cinquecento and Seicento artistic production, and the voracious appetite of English collectors for Venetian pictures in the opening decades of the seventeenth century is considered. Exploring the situations—political (the artist), economic (the dealer), and social (the patron)—present in Venice during the early seventeenth century and their direct relation to the perceived aesthetics of a cultural legacy, this project provides a reassessment of how established value sets in Venetian art were considered successful or not within their cultural context, and how those stylistic evaluations affected artists working in Venice during the early Seicento.
