description: La presente tesis de grado es un estudio semántico de los discursos que Juan Domingo Perón dio
durante sus primeras dos presidencias. En particular, este trabajo se enfocará en los discursos de
los 17 de Octubre y los Primero de Mayo, ya que fueron de suma importancia para el peronismo
en esta época. El trabajo empieza con un capítulo de historia que explicará las condiciones en la
Argentina antes de Perón, la llegada al poder de Perón y la importancia de los días feriados
mencionados anteriormente. Después, el marco teórico desarrollará los fundamentos del análisis
del discurso y los tropos semánticos estudiados en el análisis (la sinonimia, la antonimia y la
metáfora). Finalmente, se encuentra el análisis de la ocurrencia de dichos tropos dentro del
corpus de datos. La autora detalla varias estrategias encontradas para el uso de la sinonimia, la
antonimia y la metáfora. Este trabajo es pionero en el estudio de la sinonimia y la antonimia y
constituye una ampliación de las estrategias utilizadas por Perón en cuanto al uso de la metáfora.

description: We propose a universal non-linear sigma model field theory for one dimensional frustrated ferromagnets, which applies in the vicinity of a "quantum Lifshitz point", at which the ferromagnetic state develops a spin wave instability. We investigate the phase diagram resulting from perturbations of the exchange and of magnetic field away from the Lifshitz point, and uncover a rich structure with two distinct regimes of different properties, depending upon the value of a marginal, dimensionless, parameter of the theory. In the regime relevant for one dimensional systems with low spin, we find a metamagnetic transition line to a vector chiral phase. This line terminates in a critical endpoint from which emerges a cascade of multipolar phases. We show that the field theory has the property of "asymptotic solubility", so that a particular saddle point approximation becomes asymptotically exact near the Lifshitz point. Our results provide an analytic framework for prior numerical results on frustrated ferromagnets, and can be applied much more broadly.

The safety and regulatory challenges associated with the geological disposal of the UK’s higher activity radioactive waste in England and Wales
Creators: name: Marsh, Ashley Ian
Publisher: name: Imperial College London
Year: 2022

description: The UK’s higher activity waste (HAW) is set to be disposed of in a geological disposal facility (GDF). International consensus is that a GDF provides the most comprehensive means of isolating and containing HAW and its harmful radionuclides, with nations at different stages in their implementation of geological disposal. The maturity of some nations’ disposal programmes (e.g. Finland, Sweden) ensures a regulatory framework for their GDF is well established. The UK is currently engaged in a GDF site selection process, as such it is necessary that the regulatory framework for the geological disposal of its radioactive waste be fully established to meet the unique challenges posed by this first-of-a-kind facility for the UK. The reduced hazard potential and unique features of the GDF may mean the existing framework applied to UK nuclear installations does not proportionately meet the requirements for maintaining worker and public safety and the protection of the environment. The purpose of the work presented in this thesis was to investigate the safety and regulatory challenges associated with the geological disposal of UK HAW. This began by building an understanding of the fundamentals of radioactive waste and geological disposal in the UK and the risks associated with geological disposal. Having investigated the performance of proposed engineered barrier materials for the GDF, a simplified, 1-dimensional risk assessment model was developed for the disposal of spent nuclear fuel (SNF) in a hypothetical geological setting. The model was verified against data provided by Radioactive Waste Management Ltd (RWM Ltd), the UK’s GDF delivery body, and utilised to conduct sensitivity studies, for the purpose of identify factors which could significantly impact on the radiological risk to the public due to the disposal of Spent Nuclear Fuel. Where significant, it was considered whether this might impact on the nature of the regulatory oversight required. The framework applied to nuclear installations in the regulation of nuclear safety, security, environmental protection and safeguards was mapped and analysed for its applicability to GDF-specific challenges. International experience in the regulation of GDFs was drawn upon in order to identify common features. Stakeholder opinion, including members of industry, regulators, waste producers and local interest groups, was also sought, in order to highlight their views on the applicability of the current system of nuclear site licensing to a GDF. This work culminated with a proposal for a regulatory framework, which aims to proportionately address the unique challenges associated with geological disposal.

description: Societal dependence on political policy is irrefutable, and the ever-growing dipole of political ideology is grossly visible to an observant individual.  Psychological underpinnings are at the root of this partisan divide, however its importance is often overlooked.  Specifically, physiological and subjective emotional variances are often highlighted as distinguishing characteristics between conservative and liberal individuals.  This study examines the relationship between political ideology and subjective fear endorsement in response to visual stimuli.  38 participants were recruited for this experiment.  Through varied news articles their political ideology was manipulated to match either a conservative, liberal, or control belief set.  Immediately following, participants were presented with 22 images, 11 fear evoking and 11 neutral and were asked to report both their subjective levels of fear and happiness.  This study yielded a significant relationship between manipulated political ideology and the subjective emotional expression of fear.  Post-hoc testing revealed that the significant difference fell between the conservative and the control condition, with conservatives demonstrating the highest average fear scores.  Variables such as self-reported ideology, gender, voting registration status, and self-reported political ideology were also collected and analyzed for an interaction with fear expression.

description: Heat engines convert thermal energy into mechanical work both in the classical and quantum regimes. However, quantum theory offers genuine nonclassical forms of energy, different from heat, which so far have not been exploited in cyclic engines to produce useful work. We here experimentally realize a novel quantum many-body engine fuelled by the energy difference between fermionic and bosonic ensembles of ultracold particles that follows from the Pauli exclusion principle. We employ a harmonically trapped superfluid gas of $^6$Li atoms close to a magnetic Feshbach resonance which allows us to effectively change the quantum statistics from Bose-Einstein to Fermi-Dirac. We replace the traditional heating and cooling strokes of a quantum Otto cycle by tuning the gas between a Bose- Einstein condensate of bosonic molecules and a unitary Fermi gas (and back) through a magnetic field. The quantum nature of such a Pauli engine is revealed by contrasting it to a classical thermal engine and to a purely interaction-driven device. We obtain a work output of several $10^6$ vibrational quanta per cycle with an efficiency of up to $25\%$. Our findings establish quantum statistics as a useful thermodynamic resource for work production, shifting the paradigm of energy-conversion devices to a new class of emergent quantum engines.

description: We consider estimating the parameter associated with the qubit depolarizing channel when the available initial states that might be employed are mixed. We use quantum Fisher information as a measure of the accuracy of estimation to compare protocols which use collections of qubits in product states to one in which the qubits are in a correlated state. We show that, for certain parameter values and initial states, the correlated state protocol can yield a greater accuracy per channel invocation than the product state protocols. We show that, for some parameters and initial states, using more than two qubits and channel invocations is advantageous. These results stand in contrast to the known optimal case that uses pure initial states and a single channel invocation on a pair of entangled qubits.

description: We study dynamic features of a plasma consisting of gluons whose infrared dynamics is improved by the Gribov-Zwanziger quantization. This approach embodies essential features of color confinement which set the plasma apart from conventional quasiparticle systems in several aspects. Our study focusses on a boost-invariant expansion for in- and out-of-equilibrium settings, which at late times can be characterized by the sound velocity, $c_s$, and the shear, $η$, and bulk, $ζ$, viscosities. We obtain explicit expressions for the transport coefficients $η$ and $ζ$ and check that they are consistent with the numerical solutions of the kinetic equation. At high temperature, keeping both the Gribov parameter and the relaxation time constant, we find a scaling $ζ/η\propto 1/3 - c_s^2$ which manifests strong breaking of conformal symmetry in contrast to the case of weakly coupled plasmas.

description: ASD is a neurodevelopmental disorder characterized by social deficits, stereotyped and repetitive behaviors, and communication deficits while FXS is an X-linked genetic disorder that results from expansions of a CGG repeat near the promoter region of FMR1. The current study includes school age males with ASD, FXS, and typical development. Measures of motor control, communication, repetitive behaviors, and cognitive ability were examined. Anatomical 3 Tesla MRI scans were obtained. Gray matter volumes in cerebellar anterior and posterior lobes were calculated with the Diedrichsen SUIT toolbox, which uses a probabilistic atlas and semi-automated pipeline to produce the segmentations. No significant differences between groups were found for adjusted mean anterior gray matter volumes (p=0.46) or posterior lobe gray matter volumes (p=0.74). Anterior lobe gray matter volumes were not significantly associated with motor skills standard scores in ASD, FXS, or TYP groups (p=0.93). The interaction term of ASD diagnosis by posterior lobe gray matter volumes was trending toward a significant association with communication standard scores (p=0.097). Posterior lobe gray matter volumes were not significantly associated with repetitive behaviors in ASD, FXS, or TYP groups (p=1.00). These findings indicate that more research should be performed to explore cerebellar lobe gray matter volumes associations with the behaviors characteristics of ASD and FXS.

Quantum Stirling heat engine with squeezed thermal reservoir

description: We analyze the performance of a quantum Stirling heat engine (QSHE), using a two level system and the harmonic oscillator as the working medium, that contacts with a squeezed thermal reservoir and a cold reservoir. First, we derive closed-form expressions for the produced work and efficiency which strongly depends on the squeezing parameter $r_h$. Then, we prove that the effect of squeezing heats the working medium to a higher effective temperature which leads to better overall performance. In particular, the efficiency increases with the degree of squeezing surpassing the standard Carnot limit, when the ratio of temperatures of hot and cold reservoir is small. Furthermore, we derive the analytical expressions for the efficiency at maximum work and the maximum produced work in the high and low temperature regime and we find that at extreme temperatures the squeezing parameter $r_h$ does not affect the performance of the QSHE. Finally, the performance of the QSHE depends on the nature of the working medium.

description: We present results of the first ever three-dimensional (3D) magnetohydrodynamic (MHD) simulations of the accretion-ejection structure. We investigate the 3D evolution of jets launched symmetrically from single stars but also jets from warped disks in binary systems. We have applied various model setups and tested them by simulating a stable and bipolar symmetric 3D structure from a single star-disk-jet system. Our reference simulation maintains a good axial symmetry and also a bipolar symmetry for more than 600 rotations of the inner disk confirming the quality of our model setup. We have then implemented a 3D gravitational potential (Roche potential) due to a companion star and run a variety of simulations with different binary separations and mass ratios. These simulations show typical 3D deviations from axial symmetry, such as jet inclination outside the Roche lobe or spiral arms forming in the accretion disk. In order to find indication for precession effects, we have also run an exemplary parameter setup, essentially governed by a small binary separation of only $\simeq{200}$ inner disk radii. This simulation shows strong indication that we observe the onset of a jet precession caused by the wobbling of the jet launching disk. We estimate the opening angle of the precession cone defined by the lateral motion of the the jet axis of about 4 degree after about 5000 dynamical time steps.

description: Nanoparticles (NPs) are promising therapeutic delivery agents, yet it is increasingly apparent that the number and manner of presentation of cell binding ligands on the NP can affect the eventual fate of the therapeutic. Whenever NPs are conjugated with biomolecules, a heterogenous population of decorated NPs will be produced and the details of the subpopulations of particle-ligand structures needs to be characterised for a reliable interpretation of NP-based data. We report an optical microscopy method to quantitatively evaluate the conjugation on a single particle basis in samples consisting of gold NPs (GNPs) decorated with human holo-transferrin fluorescently labelled with Alexa647 (Tf). We employed widefield fluorescence and extinction microscopy on NP-ligand constructs sparesly deposited onto a glass surface, alongside a correlative analysis which spatially co-localises diffraction-limited sources of fluorescence with the optical extinction by individual GNPs. A photobleaching step analysis of the fluorescence emission was employed to estimate the number of fluorophores contributing to the detected emission rate. The method quantifies the number of fluorescent biomolecules attached per GNP, the numbers of unconjugated GNPs and unbound Tf present within the mixed population, and the size and intraparticle clustering propensity of conjugated GNPs. We found a high variability in the number of Tf ligands per GNP within the GNP population, when analysed at the single-particle level, unraveling a non-trivial statistical distribution not accessible in ensemble averaged approaches
Questioning the Creature's True Appearance: Ugliness, Otherness, and Ambiguity in Frankenstein
Creators: name: Horney, Tabatha

description: In Mary Shelley’s Frankenstein, or, the Modern Prometheus, the Creature’s monstrosity and ugliness endure as unquestioned aspects of the novel’s constant hold on the public imagination. While adaptations may differ in characterization and setting and scholars may focus on diverse thematic questions, the Creature’s ugliness remains an obvious, accepted fixture of the work. Throughout this thesis, I argue that the Creature’s ugliness should not be accepted automatically. If the Creature is repulsive, but not because of his ugliness, what makes him repulsive? Why have readers fixated on ugliness as the only explanation for his repulsiveness? What aspects of the text have readers missed because of the assumption of ugliness, rather than searching for alternative explanations? Why might Shelley have created a Creature with an ambiguous appearance? What, metaphorically, could this represent – if anything?

description: The process of protein search for specific binding sites on DNA is fundamentally important since it marks the beginning of all major biological processes. We present a theoretical investigation that probes the role of DNA sequence symmetry, heterogeneity and chemical composition in the protein search dynamics. Using a discrete-state stochastic approach with a first-passage events analysis, which takes into account the most relevant physical-chemical processes, a full analytical description of the search dynamics is obtained. It is found that, contrary to existing views, the protein search is generally faster on DNA with more heterogeneous sequences. In addition, the search dynamics might be affected by the chemical composition near the target site. The physical origins of these phenomena are discussed. Our results suggest that biological processes might be effectively regulated by modifying chemical composition, symmetry and heterogeneity of a genome.

description: Plasmonic nanocavities form very robust sub-nanometer gaps between nanometallic structures and confine light in deep subwavelength volumes to enable unprecedented control on light-matter interactions. However, spherical nanoparticles acquire various polyhedral shapes during their synthesis, which has defining impact on controlling many light-matter interactions, such as photocatalytic reactions. Here, we focus on nanocavities made of three polyhedral nanoparticles (cuboctahedron, rhombicuboctahedron, decahedron) that commonly occur during the synthesis of spherical nanoparticles. Their photonic modes have a very intricate and rich optical behaviour, both in the near- and far-field. Through a recombination technique, we obtain the total far-field produced by a molecule placed within these nanocavities, to reveal how energy couples in and out of the system. This work paves the way towards understanding and controlling light-matter interactions, such as photocatalytic reactions and non-linear vibrational pumping, in such extreme environments.
Orientalism Rearticulated: Colonial Discourse in Contemporary Representations of India in Film and Television
Creators: name: Hughes, Marsela
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: In the year 2009, a greater number of people had viewed the 2008 film "Slumdog Millionaire" about a boy from the Mumbai slums than the number of people who had visited India in that same year. As ubiquitous mediums in the United States, film and television provide representations of faraway places, peoples, and cultures for an American audience. However, film and television are not benign forms of entertainment, but are imbued with power as makers of meaning and identity. This project focuses on representations of India in the Netflix television show "The Indian Detective" and in the Hollywood movie "The Darjeeling Limited." Drawing on colonial discourse, the juxtaposition of a Mumbai crime boss with a Canadian businessman in "The Indian Detective" essentializes criminality and moral depravity as inherent to Indian identity. In "The Darjeeling Limited," the colonial trope of “Mystical India” situates India as a site for consumption by Americans in pursuit of healing and self-discovery. Through content and narrative analysis, this project argues that the representations of India in these texts operate as a contemporary manifestation of Edward Said’s epochal theory of Orientalism. The representation of India in "The Indian Detective" and "The Darjeeling Limited" is Orientalist in nature because it produces a particular knowledge about India that distinguishes Indian identity from American identity, thus allowing an American audience to have control over India.

description: We study the prerequisites for realizing superconductivity in doped triangular-lattice Mott insulators by considering three distinct parent spin backgrounds, i.e., $120^{\circ}$ antiferromagnets, quantum spin liquid, and stripy antiferromagnets, and all possible sign combinations $(τ_1, τ_2)$ of nearest-neighbor hopping and next-nearest-neighbor hopping $(t_1, t_2)$. Based on density-matrix renormalization group calculations, we find that, with finite $t_2$ and specific sign combinations $(τ_1, τ_2)$, the quasi-long-range superconductivity order can always be achieved, regardless of the nature of the parent spin backgrounds. Besides specific hopping signs $(τ_1, τ_2)$, these superconductivity phases in triangular lattices are commonly characterized by short-ranged spin correlations and two charges per stripe. In the robust superconductivity phase realized at larger $t_2/t_1$, flipping the signs $τ_2$ and $τ_1$ gives rise to the stripe phase without strong pairing and pseudogap-like phase without Cooper-pair phase coherence, respectively. Interestingly, the roles of the two hopping signs are switched at smaller $t_2/t_1$. Moreover, different sign combinations $(τ_1, τ_2)$ would stabilize distinct phases including superconductivity, charge density waves, spin density waves, and pseudogap-like phases accordingly. Our findings suggest the important role of charge kinetic energy in realizing superconductivity in doped triangular-lattice Mott insulators.

description: In this study we use multi-epoch near-infrared observations from the VISTA survey of the Magellanic Cloud system (VMC) to measure the proper motion of different stellar populations in a tile of 1.5 deg sq. in size in the direction of the Galactic globular cluster 47 Tuc. We obtain the proper motion of the cluster itself, of the Small Magellanic Cloud (SMC), and of the field Milky Way stars. Stars of the three main stellar components are selected from their spatial distribution and their distribution in colour-magnitude diagrams. Their average coordinate displacement is computed from the difference between multiple Ks-band observations for stars as faint as Ks=19 mag. Proper motions are derived from the slope of the best-fitting line among 10 VMC epochs over a time baseline of ~1 yr. Background galaxies are used to calibrate the absolute astrometric reference frame. The resulting absolute proper motion of 47 Tuc is (mu_alpha cos(delta), mu_delta)=(+7.26+/-0.03, -1.25+/-0.03) mas/yr. This measurement refers to about 35000 sources distributed between 10 and 60 arcmin from the cluster centre. For the SMC we obtain (mu_alpha cos(delta), mu_delta)=(+1.16+/-0.07, -0.81+/-0.07) mas/yr from about 5250 red clump and red giant branch stars. The absolute proper motion of the Milky Way population in the line-of-sight (l =305.9, b =-44.9) of this VISTA tile is (mu_alpha cos(delta), mu_delta)=(+10.22+/-0.14, -1.27+/-0.12) mas/yr and results from about 4000 sources. Systematic uncertainties associated to the astrometric reference system are 0.18 mas/yr. Thanks to the proper motion we detect 47 Tuc stars beyond its tidal radius.

The final-state problem for the cubic-quintic NLS with non-vanishing boundary conditions

description: We construct solutions with prescribed scattering state to the cubic-quintic NLS $$ (i\partial_t+Δ)ψ=α_1 ψ-α_{3}\vert ψ\vert^2 ψ+α_5\vert ψ\vert^4 ψ$$ in three spatial dimensions in the class of solutions with $|ψ(x)|\to c >0$ as $|x|\to\infty$. This models disturbances in an infinite expanse of (quantum) fluid in its quiescent state --- the limiting modulus $c$ corresponds to a local minimum in the energy density. Our arguments build on work of Gustafson, Nakanishi, and Tsai on the (defocusing) Gross--Pitaevskii equation. The presence of an energy-critical nonlinearity and changes in the geometry of the energy functional add several new complexities. One new ingredient in our argument is a demonstration that solutions of such (perturbed) energy-critical equations exhibit continuous dependence on the initial data with respect to the \emph{weak} topology on $H^1_x$.

description: As a contribution to the subject of the information loss paradox in (1+1)-dimensional gravitational systems, we study a model of (1+1)-dimensional dilaton gravity derived from the four-dimensional Einstein-Hilbert action by dimensional reduction. The reduced action involves the cosmological constant and admits black hole solutions. After including the back-reaction of quantum fields to 1-loop order, we solve the semi-classical field equations perturbatively and compute the quantum correction to the Hawking temperature. We consider the quantum extremal surface approach and invoke the ``island rule'' to compute the fine-grained entropy of the Hawking radiation for an eternal Schwarzschild black hole and demonstrate that it follows the unitary Page curve.

“It was very, very dangerous to live even one day”: The Urban Modern Gothic in the War Literature of Virginia Woolf and Elizabeth Bowen
Creators: name: Burk, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Virginia Woolf and Elizabeth Bowen are both legends of their time, lauded individually for their contribution to English literature. When considered together, they create a body of work that pushes back against convention, grapples with national identity and advocates for the ordinary, individual woman at the time when she needed it the most. Their works are indicative both of their shared modernist style and the Gothic characteristics made relevant by wartime terror. Through focusing on the eternal struggle of the individual in society, Woolf and Bowen develop an urban, Gothic modernism that accurately conveys on the larger scale the challenging experience of living in London in the early twentieth century.

description: DBSCAN has been widely used in density-based clustering algorithms. However, with the increasing demand for Multi-density clustering, previous traditional DSBCAN can not have good clustering results on Multi-density datasets. In order to address this problem, an adaptive Multi-density DBSCAN algorithm (AMD-DBSCAN) is proposed in this paper. An improved parameter adaptation method is proposed in AMD-DBSCAN to search for multiple parameter pairs (i.e., Eps and MinPts), which are the key parameters to determine the clustering results and performance, therefore allowing the model to be applied to Multi-density datasets. Moreover, only one hyperparameter is required for AMD-DBSCAN to avoid the complicated repetitive initialization operations. Furthermore, the variance of the number of neighbors (VNN) is proposed to measure the difference in density between each cluster. The experimental results show that our AMD-DBSCAN reduces execution time by an average of 75% due to lower algorithm complexity compared with the traditional adaptive algorithm. In addition, AMD-DBSCAN improves accuracy by 24.7% on average over the state-of-the-art design on Multi-density datasets of extremely variable density, while having no performance loss in Single-density scenarios. Our code and datasets are available at https://github.com/AlexandreWANG915/AMD-DBSCAN.

description: Synthetic RGBB magnitudes are generated with the most recent theoretical stellar evolution models computed with the Dartmouth Stellar Evolution Program (DSEP) code. They are compared to the observational work of Nataf et al., who present RGBB magnitudes for 72 globular clusters. A DSEP model using a chemical composition with enhanced $α$ capture [$α$/Fe] $ =+0.4$ and an age of 13 Gyr shows agreement with observations over metallicities ranging from [Fe/H] = $0$ to [Fe/H] $\approx-1.5$, with discrepancy emerging at lower metallicities.

description: We have designed and synthesized amide derivatives of substituted 3-methyl-benzofuran-2-carboxylic acid with aryl sulfonamide piperazines, aryl hydrazides and aryl hydrazines. All the synthesized compounds were screened for their anticancer activity against lungs cancer cell line (A549) and breast cancer cell line (MCF7) using MTT assay. Compound 12b showed excellent activity against lungs cancer cell line (A549) with IC50 value of 0.858 µM and compound 10d showed good activity against breast cancer cell line (MCF7) with IC50 value of 2.07 µM. Hence, compounds 10d and 12b were studied further for their mechanism of cytotoxicity by using EtBr/AO and LDH assay in respective cell lines. The cytostatic potential of compound 10d and 12b was uncurtail by Trypan blue exclusion assay and active involvement of ROS was quantified using DCFH-DA dye. The drug-likeliness and toxicity predictions were done using in-silico-based SwissADME and ProTox-II webserver, which confirmed negligible toxicity (Class IV).
Parabolic Anderson model in a dynamic random environment: random conductances

description: The parabolic Anderson model is defined as the partial differential equation \partial u(x,t)/\partial t = κΔu(x,t) + ξ(x,t)u(x,t), x\in\Z^d, t\geq 0, where κ\in [0,\infty) is the diffusion constant, Δis the discrete Laplacian, and ξis a dynamic random environment that drives the equation. The initial condition u(x,0)=u_0(x), x\in\Z^d, is taken to be non-negative and bounded. The solution of the parabolic Anderson equation describes the evolution of a field of particles performing independent simple random walks with binary branching: particles jump at rate 2dκ, split into two at rate ξ\vee 0, and die at rate (-ξ) \vee 0. Our focus is on the Lyapunov exponents λ_p(κ) = \lim_{t\to\infty} \frac{1}{t} \log \E([u(0,t)]^p)^{1/p}, p \in \N, and λ_0(κ) = \lim_{t\to\infty} \frac{1}{t}\log u(0,t). We investigate what happens when κΔis replaced by Δ^\cK, where \cK = \{\mathcal{K}(x,y)\colon\,x,y\in\Z^d,\,x \sim y\} is a collection of random conductances between neighbouring sites replacing the constant conductances κin the homogeneous model. We show that the associated annealed Lyapunov exponents are given by the formula λ_p(\cK) = \sup\{λ_p(κ) \colon\,κ\in\Supp(\cK)\}, where \Supp(\cK) is the set of values taken by the \cK-field. We also show that for the associated quenched Lyapunov exponent this formula only provides a lower bound. Our proof is valid for three classes of reversible ξ, and for all \cK satisfying a certain clustering property, namely, there are arbitrarily large balls where \cK is almost constant and close to any value in \Supp(\cK). What our result says is that the Lyapunov exponents are controlled by those pockets of \cK where the conductances are close to the value that maximises the growth in the homogeneous setting.

description: In recent years, there has been growing attention to interpretable machine learning models which can give explanatory insights on their behaviour. Thanks to their interpretability, decision trees have been intensively studied for classification tasks and, due to the remarkable advances in mixed integer programming (MIP), various approaches have been proposed to formulate the problem of training an Optimal Classification Tree (OCT) as a MIP model. We present a novel mixed integer quadratic formulation for the OCT problem, which exploits the generalization capabilities of Support Vector Machines for binary classification. Our model, denoted as Margin Optimal Classification Tree (MARGOT), encompasses maximum margin multivariate hyperplanes nested in a binary tree structure. To enhance the interpretability of our approach, we analyse two alternative versions of MARGOT, which include feature selection constraints inducing sparsity of the hyperplanes' coefficients. First, MARGOT has been tested on non-linearly separable synthetic datasets in a 2-dimensional feature space to provide a graphical representation of the maximum margin approach. Finally, the proposed models have been tested on benchmark datasets from the UCI repository. The MARGOT formulation turns out to be easier to solve than other OCT approaches, and the generated tree better generalizes on new observations. The two interpretable versions effectively select the most relevant features, maintaining good prediction quality.
