description: One main goal of argumentation theory is to evaluate arguments and to determine whether they should be accepted or rejected. When there is no clear answer, a third option, being undecided, has to be taken into account. Indecision is often not considered explicitly, but rather taken to be a collection of all unclear or troubling cases. However, current philosophy makes a strong point for taking indecision itself to be a proper object of consideration. This paper aims at revealing parallels between the findings concerning indecision in philosophy and the treatment of indecision in argumentation theory. By investigating what philosophical forms and norms of indecision are involved in argumentation theory, we can improve our understanding of the different uncertain evidential situations in argumentation theory.

description: Building on the success of previous missions, asteroseismic modelling will play a key role in future space-based missions, such as PLATO, CubeSpec, and Roman. Despite remarkable achievements, asteroseismology has revealed significant discrepancies in the physics of theoretical stellar models, which have the potential to bias stellar characterisation at the precision level demanded by PLATO. The current modelling strategies largely overlook magnetic activity, assuming that its effects are masked by filtering the so-called surface effects. Given the presence of activity cycles in multiple solar-like oscillators, and activity variations in a significant fraction of Kepler observations of main-sequence stars, we measured the impact of magnetic activity on the asteroseismic characterisation of the Sun based on 26.5 years of GOLF and BiSON observations. While magnetic activity is partially absorbed in the treatment of surface effects, we found a discernible imprint of the activity cycle on the determination of the solar age. Notably, this imprint persists across both BiSON and GOLF datasets, with significant variations of up to 6.5% observed between solar minima and maxima. Considering that the Sun exhibits low levels of activity, our study underscores the looming challenge posed by magnetic activity for future photometry missions, and prompts a potential reevaluation of the asteroseismic characterisation of Kepler’s most active targets.

description: We implement high-efficiency coherent excitation to a Rydberg state using stimulated Raman adiabatic passage in a cold atom electron and ion source. We achieve an efficiency of 60% averaged over the laser excitation volume with a peak efficiency of 82%, a 1.6 times improvement relative to incoherent pulsed-laser excitation. Using pulsed electric field ionization of the Rydberg atoms we create electron bunches with durations of 250 ps. High-efficiency excitation will increase source brightness, crucial for ultrafast electron diffraction experiments, and coherent excitation to high-lying Rydberg states could allow for the reduction of internal bunch heating and the creation of a high-speed single ion source.

description: Diese Dissertation beschreibt die Messung des Wirkungquerschnitts für die Produktion von ttbb in Protonkollisionen mit einer Schwerpunktsenergie von √s = 8 TeV. Der verwendete Datensatz entspricht einer integrierten Luminosität von 20.3/fb. Der Wirkungsquerschnitt wurde aus der Anzahl der Signalereignisse bestimmt, die durch harte Schnitte insbesondere auf genau 4 identifizierten b-jets, selektiert wurden, was zu einer hohen Reinheit des Signals führt. Bei der Messung wurden die präzisesten Kalibrierungen von der Jet-Energieskala und der b-jet Effizienz benutzt. Die Messung wurde in einem Referenzphasenraum durchgeführt, der daraufhin optimiert wurde, die Abhängigkeit von der Modellierung zu minimisieren. Der gemessene Wirkungsquerschnitt beträgt 18.9 ± 3.5 (stat)+5.6 (sys) ± 0.6 (Lumi) fb oder, nachdem der Beitrag von ttH(bb) und ttZ(bb) abgezogen wurde: 17.8 ± 3.5 (stat)+5.9 (sys) ± 0.6 (Lumi) fb. Das Ergebnis wurde mit einer Vielzahl von theoretischen Vorhersagen verglichen, einschließlich NLO-Berechnungen mit Partonschauern und einer Reihe von Modellen die sich in der Beschreibung der Gluon Spaltung unterscheiden. Es wurde gezeigt, dass das exstremste Model den Wirkungsquerschnitt überschätzt und dass die Messung die Vorhersagen bevorzugt, die mit einer niedrigen Renormierungs- und Faktorisierungsskala, berechnet wurden.
description: This thesis presents the measurement of the ttbb production cross-section, using a dataset of 20.3/fb of pp collisions collected with the ATLAS detector at 8 TeV. The measurement is based on a cut-and-count method, using a sample of events with exactly four b-tagged jets, which is shown to have a high purity in signal events. The measurement exploits the most precise jet energy scale and b-tagging calibrations and is performed in a fiducial phase space that is designed to minimize the model dependence of the measurement. The fiducial cross-section is measured to be 18.9 ± 3.5 (stat)+5.6 (sys) ± 0.6 (Lumi) fb or subtracting the contribution from ttH(bb) and ttZ(bb) final states, 17.8 ± 3.5 (stat)+5.9 (sys) ± 0.6 (Lumi) fb. The result is compared with a multitude of theoretical predictions, including different NLO calculations matched to a parton shower, which constitute the most precise predictions available to date, as well as with a series of models that differ in the description of the gluon splitting to b-quarks. It is shown that the most extreme gluon splitting model overestimates the observed rate of ttbb production and that the measurement favors calculations performed with renormalization/factorization scales which are softer than the scales usually employed in similar calculations.

description: Heterotic vacua of string theory are realised, at large radius, by a compact threefold with vanishing first Chern class together with a choice of stable holomorphic vector bundle. These form a wide class of potentially realistic four-dimensional vacua of string theory. Despite all their phenomenological promise, there is little understanding of the metric on the moduli space of these. What is sought is the analogue of special geometry for these vacua. The metric on the moduli space is important in phenomenology as it normalises D-terms and Yukawa couplings. It is also of interest in mathematics, since it generalises the metric, first found by Kobayashi, on the space of gauge field connections, to a more general context. Here we construct this metric, correct to first order in alpha', in two ways: first by postulating a metric that is invariant under background gauge transformations of the gauge field, and also by dimensionally reducing heterotic supergravity. These methods agree and the resulting metric is Kahler, as is required by supersymmetry. Checking that the metric is in fact Kahler is quite intricate and uses the anomaly cancellation equation for the H-field, in an essential way. The Kahler potential nevertheless takes a remarkably simple form: it is Kahler potential for special geometry with the Kahler form replaced by the alpha'-corrected hermitian form.

description: The discoveries of GW 150914, GW 151226, and LVT 151012 suggest that double black hole (BH-BH) mergers are common in the universe. If at least one of the two merging black holes carries certain amount of charge, possibly retained by a rotating magnetosphere, the inspiral of a BH-BH system would drive a global magnetic dipole normal to the orbital plane. The rapidly evolving magnetic moment during the merging process would drive a Poynting flux with an increasing wind power. The magnetospheric activities during the final phase of the merger would make a fast radio burst (FRB) if the BH charge can be as large as a factor of $\hat q \sim (10^{-9}-10^{-8})$ of the critical charge $Q_c$ of the BH. At large radii, dissipation of the Poynting flux energy in the outflow would power a short duration high-energy transient, which would appear as a detectable short-duration gamma-ray burst (GRB) if the charge can be as large as $\hat q \sim (10^{-5}-10^{-4})$. The putative short GRB coincident with GW 150914 recorded by Fermi GBM may be interpreted with this model. Future joint GW/GRB/FRB searches would lead to a measurement or place a constraint on the charges carried by isolate black holes.

description: In this paper, the problem of multi-view embedding from different visual cues and modalities is considered. We propose a unified solution for subspace learning methods using the Rayleigh quotient, which is extensible for multiple views, supervised learning, and non-linear embeddings. Numerous methods including Canonical Correlation Analysis, Partial Least Sqaure regression and Linear Discriminant Analysis are studied using specific intrinsic and penalty graphs within the same framework. Non-linear extensions based on kernels and (deep) neural networks are derived, achieving better performance than the linear ones. Moreover, a novel Multi-view Modular Discriminant Analysis (MvMDA) is proposed by taking the view difference into consideration. We demonstrate the effectiveness of the proposed multi-view embedding methods on visual object recognition and cross-modal image retrieval, and obtain superior results in both applications compared to related methods.
Intersectionality: The Experience of Race and First-Generational Status on Sense of Belonging

Publisher: name: University of Illinois at Chicago
Year: 2023

description: Overall, there has been an increase in students earning bachelor’s degrees, but for first-generation college students (FGCS), the overall percentage earning a degree is decreasing. Overall, the available literature provides information about the factors that lead to the disparities experienced by FGCS (i.e., socioeconomic factors, cultural mismatch) with some studies focused only on smaller subtypes of FGCS (i.e., specific racial or ethnic groups). Studies have also identified several potential strategies to increase a student’s sense of belonging, such as extracurricular activities, clubs and organizations, and student or faculty. Despite these efforts, FGCS continue to have disparities related to bachelor degree completion rates and a higher amounts of loans to pay off. Missing from the literature is an intersectional look at the various social identities that may be impacting FGCS sense of belonging on a college campus. This study fills the gap by utilizing a qualitative methodology from a social work perspective to gain a rich understanding of a heterogeneous sample of 10 FGCS, with 7 completing a second interview, while also interviewing 4 key university administrators, faculty, and staff to gain a better understanding of the systemic issues impacting this population. This study explores how first-generation college students experience a sense of belonging within a college, illustrated by three identified overarching themes: 1) navigating without a map, 2) paths to belonging, and 3) broader environmental supports. This findings from this study contributes to the literature by providing and intersectional look into the insufficient structures surrounding FGCS, the strengths and supports that FGCS pull from to gain a sense of belonging, and the overall family impact of a FGCS entering into a college environment.

description: We obtain general, exact formulas for the overlaps between the eigenvectors of large correlated random matrices, with additive or multiplicative noise. These results have potential applications in many different contexts, from quantum thermalisation to high dimensional statistics. We find that the overlaps only depend on measurable quantities, and do not require the knowledge of the underlying "true" (noiseless) matrices. We apply our results to the case of empirical correlation matrices, that allow us to estimate reliably the width of the spectrum of the true correlation matrix, even when the latter is very close to the identity. We illustrate our results on the example of stock returns correlations, that clearly reveal a non trivial structure for the bulk eigenvalues. We also apply our results to the problem of matrix denoising in high dimension.

description: We extend parts of the Lagrangian spectral invariants package recently developed by Leclercq and Zapolsky to the theory of Lagrangian cobordism developed by Biran and Cornea. This yields a nondegenerate Lagrangian "spectral metric" which bounds the Lagrangian "cobordism metric" (recently introduced by Cornea and Shelukhin) from below. It also yields a new numerical Lagrangian cobordism invariant as well as new ways of computing certain asymptotic Lagrangian spectral invariants explicitly.

Influence of matter geometry on shocked flows-I: Accretion in the Schwarzschild metric

description: This work presents a comprehensive and extensive study to illustrate how the geometrical configurations of low angular momentum axially symmetric general relativistic matter flow in Schwarzschild metric may influence the formation of energy preserving shocks for adiabatic/polytropic accretion as well as of temperature preserving dissipative shocks for for the isothermal accretion onto non-rotating astrophysical black holes. The dynamical and thermodynamic states of post shock polytropic and isothermal flow have been studied extensively for three possible matter geometries, and it has been thoroughly discussed about how such states depend on the flow structure, even when the self gravity and the back reaction on the metric are not taken into account. Main purpose of this paper is thus to mathematically demonstrate that for non-self gravitating accretion, various matter geometry, in addition to the corresponding space-time geometry, controls the shock induced phenomena as observed within the black hole accretion discs. This work is expected to reveal how the shock generated phenomena (emergence of the outflows/flare or the behaviour of QPO of the associated light curves) observed at the close proximity of the horizon depends on the physical environment of the source harbouring a supermassive black hole.

description: Background: The association of serum bilirubin concentrations with kidney function and albuminuria has not been established in the US general population. Methods: We performed a cross-sectional analysis of data from the National Health and Nutrition Examination Survey (NHANES) 2001–2006 and examined the associations of serum total bilirubin concentrations with estimated glomerular filtration rate (eGFR) and albuminuria in a nationally representative sample of 13,184 adults aged 20 years or older. eGFR was estimated using the abbreviated Modification of Diet in Renal Disease equation. Urinary albumin excretion was measured using the albumin/creatinine ratio. Results: An eGFR <60 mL/min/1.73 m2 and urinary albumin/creatinine ratio ≥30 mg/g were present in 8.1% (n=1072) and 10.6% (n=1402) of participants, respectively. A total of 427 (3.2%) individuals had a serum total bilirubin concentration >22.23 μmol/L. After adjustment for demographics, comorbidities, alcohol consumption, viral hepatitis status and other laboratory measures, serum bilirubin was negatively associated with eGFR, and positively with albuminuria both in the whole cohort and in the subgroup of non-diabetic individuals. In contrast, serum bilirubin was not significantly associated with eGFR or albuminuria in persons with diabetes (n=1253). Conclusions: Increasing serum concentrations of total bilirubin are independently associated with decreasing eGFR and increasing albuminuria in the US adult population.

description: We consider self-gravitating fluids in cosmological spacetimes with Gowdy symmetry on the torus $T^3$ and, in this class, we solve the singular initial value problem for the Einstein-Euler system of general relativity, when an initial data set is prescribed on the hypersurface of singularity. We specify initial conditions for the geometric and matter variables and identify the asymptotic behavior of these variables near the cosmological singularity. Our analysis of this class of nonlinear and singular partial differential equations exhibits a condition on the sound speed, which leads us to the notion of sub-critical, critical, and super-critical regimes. Solutions to the Einstein-Euler systems when the fluid is governed by a linear equation of state are constructed in the first two regimes, while additional difficulties arise in the latter one. All previous studies on inhomogeneous spacetimes concerned vacuum cosmological spacetimes only.

Covalent bonds against magnetism in transition metal compounds

description: Magnetism in transition metal compounds is usually considered starting from a description of isolated ions, as exact as possible, and treating their (exchange) interaction at a later stage. We show that this standard approach may break down in many cases, especially in $4d$ and $5d$ compounds. We argue that there is an important intersite effect -- an orbital-selective formation of covalent metal-metal bonds, which leads to an "exclusion" of corresponding electrons from the magnetic subsystem, and thus strongly affects magnetic properties of the system. This effect is especially prominent for noninteger electron number, when it results in suppression of the famous double exchange, the main mechanism of ferromagnetism in transition metal compounds. We study this novel mechanism analytically and numerically and show that it explains magnetic properties of not only several $4d-5d$ materials, including Nb$_2$O$_2$F$_3$ and Ba$_5$AlIr$_2$O$_{11}$, but can also be operative in $3d$ transition metal oxides, e.g. in CrO$_2$ under pressure. We also discuss the role of spin-orbit coupling on the competition between covalency and magnetism. Our results demonstrate that strong intersite coupling may invalidate the standard single-site starting point for considering magnetism, and can lead to a qualitatively new behaviour.

description: In all known fermionic superfluids, Cooper pairs are composed of spin-1/2 quasi-particles that pair to form either spin-singlet or spin-triplet bound states. The "spin" of a Bloch electron, however, is fixed by the symmetries of the crystal and the atomic orbitals from which it is derived, and in some cases can behave as if it were a spin-3/2 particle. The superconducting state of such a system allows pairing beyond spin-triplet, with higher spin quasi-particles combining to form quintet or septet pairs. Here, we report evidence of unconventional superconductivity emerging from a spin-3/2 quasiparticle electronic structure in the half-Heusler semimetal YPtBi, a low-carrier density noncentrosymmetric cubic material with a high symmetry that preserves the $p$-like $j=3/2$ manifold in the Bi-based $Γ_8$ band in the presence of strong spin-orbit coupling. With a striking linear temperature dependence of the London penetration depth, the existence of line nodes in the superconducting order parameter $Δ$ is directly explained by a mixed-parity Cooper pairing model with high total angular momentum, consistent with a high-spin fermionic superfluid state. We propose a $\mathbf{k\cdot p}$ model of the $j=3/2$ fermions to explain how a dominant $J$=3 septet pairing state is the simplest solution that naturally produces nodes in the mixed even-odd parity gap. Together with the underlying topologically non-trivial band structure, the unconventional pairing in this system represents a truly novel form of superfluidity that has strong potential for leading the development of a new generation of topological superconductors.

description: We analyse solutions of the MHD equations around the electroweak transition taking into account the effects of the chiral anomaly. It is shown that a transition that is not of the first order has direct consequences on the evolution of the asymmetry between left- and right-handed leptons. Assuming an initial chiral asymmetry in the symmetric phase at temperatures higher than the transition temperature, as well as the existence of magnetic fields, it is demonstrated that the asymmetry typically grows with time, until it undergoes a fast decrease at the transition, and then eventually gets damped at lower temperatures in the broken phase. We argue that it is unlikely to have any significant magnetic field amplification as a consequence of the electroweak transition in the Standard model, even when the chiral anomaly is introduced. The presence of a chiral asymmetry between left- and right-handed charge carriers naturally leads to the creation of helical magnetic fields from non-helical fields and this can have consequences on their subsequent evolution.

description: We study a novel class of higher curvature gravity models in $n$ spacetime dimensions which we call Ricci polynomial gravity. The action is consisted purely of a polynomial in Ricci curvature of order $N$. In the absence of the second order terms in the action, the models are ghost free around the Minkowski vacuum. By appropriately choosing the coupling coefficients in front of each terms in the action, it is shown that the models can have multiple vacua with different effective cosmological constants, and can be made free of ghost and scalar degrees of freedom around at least one of the maximally symmetric vacua for any $n>2$ and any $N\geq 4$. We also discuss some of the physical implications of the existence of multiple vacua in the contexts of black hole physics and cosmology.

Quantification of emotions in decision making

description: The problem of quantification of emotions in the choice between alternatives is considered. The alternatives are evaluated in a dual manner. From one side, they are characterized by rational features defining the utility of each alternative. From the other side, the choice is affected by emotions labeling the alternatives as attractive or repulsive, pleasant or unpleasant. A decision maker needs to make a choice taking into account both these features, the utility of alternatives and their attractiveness. The notion of utility is based on rational grounds, while the notion of attractiveness is vague and rather is based on irrational feelings. A general method, allowing for the quantification of the choice combining rational and emotional features is described. Despite that emotions seem to avoid precise quantification, their quantitative evaluation is possible at the aggregate level. The analysis of a series of empirical data demonstrates the efficiency of the approach, including the realistic behavioral problems that cannot be treated by the standard expected utility theory.

Effects of Adverse Childhood Experiences, Allostatic Load, and Genetics on Risk of Breast Cancer

description: Biological embodiment is the process by which social experiences get under the skin. Adverse childhood experiences (ACEs) during key developmental periods have been demonstrated to impact long-term health outcomes by various mechanisms. ACEs may include any psychological, physical or sexual abuse, neglect, instability, and more. ACEs have been linked with an increase in risk factors such as smoking, alcohol consumption, and poor dietary habits. Additionally, changes in epigenetic profiles, inflammatory response, metabolic changes, and other physiological changes provide biological mechanisms by which disease risk may be influenced. Allostasis, the biological process by which our bodies accommodate stressful events, is increasingly being explored for its utility in predicting poor health outcomes. The allostatic load framework, which leverages measures of dysregulation across biological systems, may provide an objective measure for stress and adversity. The role that these two measures of stress and adversity play in chronic disease has been well established, however little evidence exists on their association with breast cancer risk. Using early life adversity data coupled with blood-based biomarkers from the UK Biobank, we assessed for associations between ACEs, AL, and breast cancer in females. We identified strong associations between reported ACEs and AL in adulthood in female participants of the UK Biobank, a finding that is consistent with existing literature. Our assessment of breast cancer as it relates to ACEs incorporated both prevalent and incident breast cancer cases, while associations with AL focused on incident BCa diagnoses (occurring after the biomarkers were collected.) We identified a null association between reported ACEs and breast cancer, though with a trend towards an inverse association. Effect modification by history of mammography was identified, indicating that non-screen detected breast cancers were more likely to be identified in women with a higher reported ACE burden. Positive associations between AL and breast cancer were observed, with a 3% increase in breast cancer risk with every one point increase in AL. Notably, this association was impacted by menopausal status at time of enrollment, with the association becoming negative in pre-menopausal women. Genetic risk as assessed by a validated polygenic risk score did not appear to modify the observed associations between either ACEs or AL and breast cancer.

Intuitionistic nonstandard bounded modified realisability and functional interpretation

Publisher: name: arXiv

Subjects: subject: Logic (math.LO)
subject: FOS: Mathematics

description: We present a bounded modified realisability and a bounded functional interpretation of intuitionistic nonstandard arithmetic with nonstandard principles. The functional interpretation is the intuitionistic counterpart of Ferreira and Gaspar's functional interpretation and has similarities with Van den Berg, Briseid and Safarik's functional interpretation but replacing finiteness by majorisability. We give a threefold contribution: constructive content and proof-theoretical properties of nonstandard arithmetic; filling a gap in the literature; being in line with nonstandard methods to analyse compactness arguments.

description: We derive the exact third-order analytic solution of the matter density fluctuation in the proper-time hypersurface in a $Λ$CDM universe, accounting for the explicit time-dependence and clarifying the relation to the initial condition. Furthermore, we compare our analytic solution to the previous calculation in the comoving gauge, and to the standard Newtonian perturbation theory by providing Fourier kernels for the relativistic effects. Our results provide an essential ingredient for a complete description of galaxy bias in the relativistic context.

description: We present a compact formula for the supersymmetric partition function of 2d N=(2,2), 3d N=2 and 4d N=1 gauge theories on $Σ_g \times T^n$ with partial topological twist on $Σ_g$, where $Σ_g$ is a Riemann surface of arbitrary genus and $T^n$ is a torus with n=0,1,2, respectively. In 2d we also include certain local operator insertions, and in 3d we include Wilson line operator insertions along $S^1$. For genus g=1, the formula computes the Witten index. We present a few simple Abelian and non-Abelian examples, including new tests of non-perturbative dualities. We also show that the large N partition function of ABJM theory on $Σ_g \times S^1$ reproduces the Bekenstein-Hawking entropy of BPS black holes in AdS$_4$ whose horizon has $Σ_g$ topology.

description: We exploit the key concepts of the augmented version of superfield approach to Becchi-Rouet-Stora-Tyutin (BRST) formalism to derive the superspace (SUSP) dual unitary operator (and its Hermitian conjugate) and demonstrate their utility in the derivation of the nilpotent and absolutely anticommuting (anti-)dual BRST symmetry transformations for a set of interesting models of the Abelian 1-form gauge theories. These models are the one (0+1)-dimensional (1D) rigid rotor, modified versions of the two (1+1)-dimensional (2D) Proca as well as anomalous gauge theories and 2D model of a self-dual bosonic field theory. We show the universality of the SUSP dual unitary operator and its Hermitian conjugate in the cases of all the Abelian models under consideration. These SUSP dual unitary operators, besides maintaining the explicit group structure, provide the alternatives to the dual-horizontality condition (DHC) and dual-gauge invariant restrictions (DGIRs) of the superfield formalism. The derivation of the dual unitary operators and corresponding (anti-)dual BRST symmetries are completely novel results in our present investigation.
