description: We develop a novel, fundamental and surprisingly simple randomized iterative method for solving consistent linear systems. Our method has six different but equivalent interpretations: sketch-and-project, constrain-and-approximate, random intersect, random linear solve, random update and random fixed point. By varying its two parameters$-$a positive definite matrix (defining geometry), and a random matrix (sampled in an independently and identically distributed fashion in each iteration)$-$we recover a comprehensive array of well-known algorithms as special cases, including the randomized Kaczmarz method, randomized Newton method, randomized coordinate descent method and random Gaussian pursuit. We naturally also obtain variants of all these methods using blocks and importance sampling. However, our method allows for a much wider selection of these two parameters, which leads to a number of new specific methods. We prove exponential convergence of the expected norm of the error in a single theorem, from which existing complexity results for known variants can be obtained. However, we also give an exact formula for the evolution of the expected iterates, which allows us to give lower bounds on the convergence rate.

Assessing changes induced by in utero low protein dietary exposure in offspring development and behaviour
Creators: name: Prodani, Chiara
Publisher: name: Imperial College London
Year: 2020

description: Embryonic development involves temporal and spatial coordination of epigenetic processes, which are exquisitely sensitive to environmental influences and can have life-long implications for disease if disrupted. In this thesis, I examined the impact of gestational diet, specifically protein restriction, on the expression of cyclin-dependent kinase inhibitor C1 (Cdkn1c), a gene that is epigenetically regulated through genomic imprinting, during development and post-natally, with an allele-specific bioluminescent reporter mouse model. I showed that in utero low protein diet (LPD) exposure affects behaviour in adolescence and adulthood, through changes in the dopamine system at a transcriptional, cellular and metabolic level. Sensitisation experiments suggest that adult LPD mice are hypersensitive to cocaine, as they show increased locomotor activity compared to controls, and increased stereotypy at higher doses. Adult LPD mice also show hyperactivity and reduced anxiety, which are phenotypes frequently observed in hyperdopaminergic mouse models. Adolescent LPD mice demonstrated impaired motor function, in contrast to age-matched controls, based on open field and rotarod performance. However, I have shown this deficit to be transient and resolved by adulthood. Juvenile and adult LPD-exposed mice displayed a 25% increase in midbrain dopaminergic neuron numbers. Moreover, RNA analysis from adult midbrains showed a downregulation of the gene that encodes dopamine transporter (DAT) and upregulation of dopamine receptor 5 (D5) in LPD mice, with many other dopamine-related genes unaffected. A pilot RNA-seq experiment on midbrain neuronal nuclei identified 123 differentially expressed genes in LPD mice, affecting cholesterol synthesis and markers linked to neurodegeneration and early-life stress. Lastly, μPET imaging revealed elevated striatal dopamine synthesis capacity in adult LPD mice, recapitulating one of the hallmarks of schizophrenia, and in accordance with reports of gestational exposure to famine inferring increased susceptibility to schizophrenia. This work sheds light on consequences of early-life adversity and epigenetic disruption on embryonic brain development, behaviour and disease risk.

description: Healthcare simulations help learners develop teamwork and clinical skills in a risk-free setting, promoting reflection on real-world practices through structured debriefs. However, despite video's potential, it is hard to use, leaving a gap in providing concise, data-driven summaries for supporting effective debriefing. Addressing this, we present TeamVision, an AI-powered multimodal learning analytics (MMLA) system that captures voice presence, automated transcriptions, body rotation, and positioning data, offering educators a dashboard to guide debriefs immediately after simulations. We conducted an in-the-wild study with 56 teams (221 students) and recorded debriefs led by six teachers using TeamVision. Follow-up interviews with 15 students and five teachers explored perceptions of its usefulness, accuracy, and trustworthiness. This paper examines: i) how TeamVision was used in debriefing, ii) what educators found valuable and challenging, and iii) perceptions of its effectiveness. Results suggest TeamVision enables flexible debriefing and highlights the challenges and implications of using AI-powered systems in healthcare simulation.

Infrastructural Violence And The Afterlives Of Road Building: Creating A Haitian Space In 20th Century Occupied Haiti
Creators: name: Scheffer, Nicolas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The U.S Occupation of Haiti (1915-1934) marked a transition in the internal flow of resources within Haiti and its relation with other states. During this period U.S. investments flooded the country, precipitated by the construction of large-scale road projects that connected the previously isolated countryside (both physically and politically) to the port city of Port-au-Prince. This period of centralization coincides with dependency on the U.S. and the resurgence of plantations and forced labor. This thesis reflects on the historical geography of transportation infrastructure and the spatial organization of labor in Haiti. I explore how U.S. Marines utilized road building as a technology of rule, demonstrating the coupling of violent forced labor and racist rhetoric implicated in road construction as a spatial logic that excludes and subordinates black bodies. The legacies of these infrastructure projects continue to resonate in contemporary urban planning and disaster reconstruction in Haiti.

description: Massive young star clusters contain dozens or hundreds of massive stars that inject mechanical energy in the form of winds and supernova explosions, producing an outflow which expands into their surrounding medium, shocking it and forming structures called superbubbles. The regions of shocked material can have temperatures in excess of 10$^6$ K, and emit mainly in thermal X-rays (soft and hard). This X-ray emission is strongly affected by the action of thermal conduction, as well as by the metallicity of the material injected by the massive stars. We present three-dimensional numerical simulations exploring these two effects, metallicity of the stellar winds and supernova explosions, as well as thermal conduction.

Electron-phonon coupling and energy flow in a simple metal beyond the two-temperature approximation

description: The electron-phonon coupling and the corresponding energy exchange was investigated experimentally and by ab initio theory in non-equilibrium states of the free-electron metal aluminium. The temporal evolution of the atomic mean squared displacement in laser-excited thin free-standing films was monitored by femtosecond electron diffraction. The electron-phonon coupling strength was obtained for a range of electronic and lattice temperatures from density functional theory molecular dynamics (DFT-MD) simulations. The electron-phonon coupling parameter extracted from the experimental data in the framework of a two-temperature model (TTM) deviates significantly from the ab initio values. We introduce a non-thermal lattice model (NLM) for describing non-thermal phonon distributions as a sum of thermal distributions of the three phonon branches. The contributions of individual phonon branches to the electron-phonon coupling are considered independently and found to be dominated by longitudinal acoustic phonons. Using all material parameters from first-principle calculations besides the phonon-phonon coupling strength, the prediction of the energy transfer from electrons to phonons by the NLM is in excellent agreement with time-resolved diffraction data. Our results suggest that the TTM is insufficient for describing the microscopic energy flow even for simple metals like aluminium and that the determination of the electron-phonon coupling constant from time-resolved experiments by means of the TTM leads to incorrect values. In contrast, the NLM describing transient phonon populations by three parameters appears to be a sufficient model for quantitatively describing electron-lattice equilibration in aluminium. We discuss the general applicability of the NLM and provide a criterion for the suitability of the two-temperature approximation for other metals.

Understanding and Controlling the Optoelectronic Properties of Hybrid Perovskites for Photovoltaics
Creators: name: Van Brackle, Charles H
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Organic-inorganic hybrid perovskites (OIHP) have arisen in the past decade as a highly promising high-efficiency, low-cost technology for many semiconductor applications such as light emitting diodes (LEDs), radiation detection, and particularly photovoltaics. Relatively cheap materials and solution processability suggest low costs for perovskite solar cells (PSCs), but limits on efficiency and particularly stability ultimately limit their commercialization. To realize the full potential of PSCs, greater understanding and control of their optoelectronic properties and the tools used to probe them is needed. Here, a model of charge carrier dynamics demonstrates the effects of charge carrier trapping seen in time-resolved photoluminescence (TRPL) measurements, allowing for more accurate interpretation of the resultant decay lifetimes used to assess compositions or passivating agents. The efficiency of large-area PSC modules is increased through the development of large-area polymer scattering layers with improved light management that reduce reflective losses and increase photon absorption.

description: We report on a possibility of efficient engineering of the acoustic phonon energy spectrum in multishell tubular structures produced by a novel high-tech method of self-organization of nano- and micro-architectures. The strain-driven roll-up procedure paved the way for novel classes of metamaterials such as single semiconductor radial micro- and nano-crystals and multi-layer spiral micro- and nano-superlattices. The acoustic phonon dispersion is determined by solving the equations of elastodynamics for InAs and GaAs material systems. It is shown that the number of shells is an important control parameter of the phonon dispersion together with the structure dimensions and acoustic impedance mismatch between the superlattice layers. The obtained results suggest that rolled up nano-architectures have potential for thermoelectric applications owing to a possibility of significant reduction of the thermal conductivity without degradation of the electronic transport.

description: We present the differential rates for exclusive $\Bbar\to X \ell_1 \ell_2$, where $\ell_1$ is a charged massless lepton and $\ell_2$ is a charged or neutral massless lepton, and $X$ is a mesonic system up to spin 2. The cases of interest are semileptonic (SL) $\Bbar\to \xcu\ellm \barnuell$ decays, and $\Bbar \to X_s \ellm \ellp$ where the the di-lepton can be $c \bar{c}$ resonances or non-resonant electroweak penguins (EWP). We consider helicity amplitudes having non-zero relative phases that can be potential new sources for CP-violation. Our motivations for these additional phases include a complex right-handed admixture in the hadronic weak charged current for the SL decays and complex Wilson coefficients in the effective Hamiltonians for the EWP decays. We demonstrate the efficacy of a novel technique of projecting out the individual angular moments in the full rate expression in a model-independent fashion. Our work is geared towards ongoing data analyses at $\babar$ and LHCb.

description: Identifying an appropriate covariance function is one of the primary interests in spatial and spatiotemporal data analysis because it allows researchers to analyze the dependence structure and predict unobserved values of the process. For this purpose, spatial homogeneity and temporal stationarity are widely used assumptions, and many parameterized covariance models have been developed under these assumptions. However, these are strong and unrealistic conditions in many cases. In addition, different statistical approaches should be applied to build a proper covariance model on the sphere. In this research, we introduce novel parameterized models of the covariance function for spatially non-homogeneous and temporally non-stationary random processes on the sphere. To alleviate the spatial homogeneity assumption and consider its spherical domain, this research applies the theories of intrinsic random functions (IRF) and considers the influence of time components in the model. A random process with stationary increments is applied to relax the assumption of the temporal stationarity. We also provide a methodology to estimate the associated parameters for the model. Finally, the simulation study demonstrates the validity of the suggested covariance model with its advantage of interpretability.

Appearing in the transformation formulae are generalizations of Dedekind sums involving the periodic Bernoulli function. Reciprocity theorems are proved for these Dedekind sums. Furthermore, as an application of the transformation formulae, relations between various infinite series and evaluations of several infinite series are deduced. Finally, we consider these sums for some special cases.

The domestic and foreign swap leg cash flows can be fixed or floating. The model outlined here is called a Multi-Currency Terminal Swap Rate Model which generalizes a Terminal Swap Rate Model to incorporate foreign exchange. The main idea behind a Terminal Swap Rate Model is to assume that the discount factors at the option maturity can be written as a function of the underlying swap rates.

description: The analytic theory presented in Paper I is converted into a form convenient for numerical analysis. A fast and accurate code has been written using this numerical formulation. The results are presented by first defining a reference set of physical parameters based on experimental data from high performance discharges. Numerically obtained scaling relations of maximum achievable elongation versus inverse aspect ratio are obtained for various values of poloidal beta, wall radius and feedback capability parameter in ranges near the reference values. It is also shown that each value of maximum elongation occurs at a corresponding value of optimized triangularity, whose scaling is also determined as a function of inverse aspect ratio. The results show that the theoretical predictions of maximum elongation are slightly higher than experimental observations for high performance discharges as measured by high average pressure. The theoretical optimized triangularity values are noticeably lower. We suggest that the explanation is associated with the observation that high performance involves not only MHD considerations, but also transport as characterized by confinement time. Operation away from the MHD optimum may still lead to higher performance if there are more than compensatory gains in the confinement time. Unfortunately, while the empirical scaling of the confinement time with the elongation has been determined, the dependence on the triangularity has still not been quantified. This information is needed in order to perform more accurate overall optimizations in future experimental designs.

description: An R-matrix model for three-body final states is presented and applied to a recent measurement of the neutron energy spectrum from the T+T->2n+alpha reaction. The calculation includes the n-alpha and n-n interactions in the final state, angular momentum conservation, antisymmetrization, and the interference between different channels. A good fit to the measured spectrum is obtained, where clear evidence for the 5He ground state is observed. The model is also used to predict the alpha-particle spectrum from T+T as well as particle spectra from 3He+3He. The R-matrix approach presented here is very general, and can be adapted to a wide variety of problems with three-body final states.

description: Aquest article se centra en la descripció de l’altra mirada de la València del segle XV, la de la marginació social, que es podia manifestar pel fet d’exercir diversos oficis considerats com a immorals. En les pàgines següents s’ofereix una descripció de dos col·lectius femenins particularment tractats com a vils i menyspreables: el de les curanderes, fetilleres i bruixes, la força de les quals hom considerava que partia d’un origen demoníac, i el de les prostitutes, dedicades a cobrir un «mal menor» en la societat, però vistes com a indignes per la societat a causa de l’exercici pràctic del seu ofici.

Assessing and enhancing adversarial robustness in context and applications to speech security

description: Designing artificial intelligence models that are robust to adversarial perturbations of their inputs is a highly desirable objective, as such models would not only be less prone to security breaches but also better aligned with human reasoning and perception. Neural Automatic Speech Recognition (ASR) is vulnerable to these adversarial perturbations but currently lacks defenses with strong evidence for robustness to state-of-the-art attacks. This contrasts with image tasks for which several defense algorithms have shown increasingly good results even against adaptive adversaries. Another odd aspect of speech robustness is the lack of transferability between different models for most adversarial attacks. The specifics of ASR as a task certainly play an important role in this odd situation: at their core speech utterances are time series in an infinite-dimensional Hilbert space with an underlying semantic structure, while transcription outputs belong to an infinite metric space. The objective of this thesis is to explore the dependencies between adversarial perturbations and the context in which it is studied (nature of the task, set of outputs, etc.), in order to assess their threat against speech recognition models and the possibility for robust ASR. Specifically, (1) we show that adversarial robustness is closely related to training methods and model architectures. We propose novel methods to study this relationship without the cost of training robust models, by measuring the randomness in robustness on undefended models and by quantifying the number of adversarial perturbations on a hypersphere. (2) we quantify the threat posed by adversarial attacks on ASR, both under white-box and black-box threat models. We introduce an evaluation framework and apply it notably to show that self-supervised speech models are uniquely vulnerable to transferable attacks. We also take into account the specifics of voice assistants trained on user data and investigate applications of adversarial perturbations for privacy attacks. (3) we investigate two approaches to increase ASR robustness. First, we show that the Randomized Smoothing defense paradigm enables us to combine the strengths of general machine learning defense guarantees and domain-specific speech processing tools. Using it we achieve state-of-the-art ASR robustness against state-of-the-art white-box attacks for several model architectures. Then we introduce a novel framework called adversarial masked prediction, that lets us robustly pretrain self-supervised speech models.

description: Starting with the early alchemists, a holy grail of science has been to make desired materials by modifying the attributes of basic building blocks. Building blocks that show promise for assembling new complex materials can be synthesized at the nanoscale with attributes that would astonish the ancient alchemists in their versatility. However, this versatility means that making direct connection between building block attributes and bulk behavior is both necessary for rationally engineering materials, and difficult because building block attributes can be altered in many ways. Here we show how to exploit the malleability of the valence of colloidal nanoparticle "elements" to directly and quantitatively link building block attributes to bulk behavior through a statistical thermodynamic framework we term "digital alchemy". We use this framework to optimize building blocks for a given target structure, and to determine which building block attributes are most important to control for self assembly, through a set of novel thermodynamic response functions, moduli and susceptibilities. We thereby establish direct links between the attributes of colloidal building blocks and the bulk structures they form. Moreover, our results give concrete solutions to the more general conceptual challenge of optimizing emergent behaviors in nature, and can be applied to other types of matter. As examples, we apply digital alchemy to systems of truncated tetrahedra, rhombic dodecahedra, and isotropically interacting spheres that self assemble diamond, FCC, and icosahedral quasicrystal structures, respectively.

description: December media coverage of climate change or global warming in newspapers around the globe dropped 36% from November 2022 but remained 8% higher than December 2021 levels. International wire services similarly decreased 36%. Radio coverage also dipped 45% from November 2022. Compared to the previous month, coverage was pretty consistently down in all regions: North America (-29%), Asia (-30%), Oceania (-30%), the European Union (EU) (-40%), the Middle East (-45%), Latin America (-46%), and Africa (-56%). Figure 1 shows trends in newspaper media coverage at the global scale – organized into seven geographical regions around the world – from January 2004 through December 2022.

description: In this paper we classify and derive closed formulas for geometric elements of quadrics in rational Bézier triangular form (such as the center, the conic at infinity, the vertex and the axis of paraboloids and the principal planes), using just the control vertices and the weights for the quadric patch. The results are extended also to quadric tensor product patches. Our results rely on using techniques from projective algebraic geometry to find suitable bilinear forms for the quadric in a coordinate-free fashion, considering a pencil of quadrics that are tangent to the given quadric along a conic. Most of the information about the quadric is encoded in one coefficient, involving the weights of the patch, which allows us to tell apart oval from ruled quadrics. This coefficient is also relevant to determine the affine type of the quadric. Spheres and quadrics of revolution are characterised within this framework.

A Defense of the Semantic View of Thick Concepts
Creators: name: Johnson, Miriam Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Pekka Vayrynen (2013) argues that the significance often attributed to thick ethical terms in philosophy depends on a false assumption: that the evaluations conveyed by our use of these terms is part of their semantic content. Contrary to this “semantic view,” Vayrynen claims, thick evaluations are best thought of as a species of pragmatic implication, meaning that evaluation is not an essential feature of most thick concepts. This paper responds to Vayrynen’s core thesis and argues that it ought to be rejected. Contrary to Vayrynen’s claims, the pragmatic view does not more accurately capture the linguistic data that he cites, nor does it offer a simpler explanation of thick evaluation than the semantic view. This paper does not offer a substantive defense of the metaphysical significance of thick terms, aiming instead to defend thick terms as a semantic category.
