description: Automatic analysis of facial actions (AFA) can reveal a person’s emotion, intention, and physical state, and make possible a wide range of applications. To enable reliable, valid, and efficient AFA, this thesis investigates automatic analysis of facial actions through transductive, supervised and unsupervised learning. Supervised learning for AFA is challenging, in part, because of individual differences among persons in face shape and appearance and variation in video acquisition and context. To improve generalizability across persons, we propose a transductive framework, Selective Transfer Machine (STM), which personalizes generic classifiers through joint sample reweighting and classifier learning. By personalizing classifiers, STM offers improved generalization to unknown persons. As an extension, we develop a variant of STM for use when partially labeled data are available. Additional challenges for supervised learning include learning an optimal representation for classification, variation in base rates of action units (AUs), correlation between AUs and temporal consistency. While these challenges could be partly accommodated with an SVM or STM, a more powerful alternative is afforded by an end-to-end supervised framework (i.e., deep learning). We propose a convolutional network with long short-term memory (LSTM) and multi-label sampling strategies. We compared SVM, STM and deep learning approaches with respect to AU occurrence and intensity in and between BP4D+ [282] and GFT [93] databases, which consist of around 0.6 million annotated frames. Annotated video is not always possible or desirable. We introduce an unsupervised Branch-and-Bound framework to discover correlated facial actions in un-annotated video. We term this approach Common Event Discovery (CED). We evaluate CED in video and motion capture data. CED achieved moderate convergence with supervised approaches and enabled discovery of novel patterns occult to supervised approaches.

description: Market makers are unique entities in a market ecosystem. Unlike other participants that have exposure (either speculative or endogenous) to potential future states of the world, market making agents either endeavor to secure a risk-free profit or to facilitate trade that would otherwise not occur. In this thesis we present a principled theoretical framework for market making along with applications of that framework to different contexts. We begin by presenting a synthesis of two concepts—automated market making from the artificial intelligence literature and risk measures from the finance literature—that were developed independently. This synthesis implies that the market making agents we develop in this thesis also correspond to better ways of measuring the riskiness of a portfolio—an important application in quantitative finance. We then present the results of the Gates Hillman Prediction Market (GHPM), a fielded large-scale test of automated market making that successfully predicted the opening date of the new computer science buildings at CMU. Ranging over 365 possible opening days, the market’s large event partition required new advances like a novel span-based elicitation interface. The GHPM uncovered some practical flaws of automated market makers; we investigate how to rectify these failures by describing several classes of market makers that are better at facilitating trade in Internet prediction markets. We then shift our focus to notions of profit, and how a market maker can trade to maximize its own account. We explore applying our work to one of the largest and most heavily-traded markets in the world by recasting market making as an algorithmic options trading strategy. Finally, we investigate optimal market makers for fielding wagers when good priors are known, as in sports betting or insurance.

description: We present the implementation of Dynamical Mean-Field Theory (DMFT) in the CASTEP \emph{ab-initio} code. We explain in detail the theoretical framework for DFT+DMFT and we demonstrate our implementation for three strongly-correlated systems with $f$-shell electrons: $γ$-cerium, cerium sesquioxide Ce$_{2}$O$_{3}$ and samarium telluride SmTe by using a Hubbard I solver. We find very good agreement with previous benchmark DFT+DMFT calculations of cerium compounds, while for SmTe, which was never studied within DFT+DMFT before to the best of our knowledge, we show the improved agreement with the experimental structural parameters as compared with LDA. Our implementation works equally well for both norm-conserving and ultra-soft pseudopotentials, and we apply it to the calculation of total energy, bulk modulus, equilibrium volumes and internal forces in the two cerium compounds. In Ce$_{2}$O$_{3}$ we report a dramatic reduction of the internal forces acting on coordinates not constrained by unit cell symmetries. This reduction is induced by the many-body effects, which can only be captured at the DMFT level. In addition, we derive an alternative form for treating the high-frequency tails of the Green function in Matsubara frequency summations. Our treatment allows a reduction in the bias when calculating the correlation energies and occupation matrices to high precision.

description: The $k$-means algorithm is arguably the most popular nonparametric clustering method but cannot generally be applied to datasets with incomplete records. The usual practice then is to either impute missing values under an assumed missing-completely-at-random mechanism or to ignore the incomplete records, and apply the algorithm on the resulting dataset. We develop an efficient version of the $k$-means algorithm that allows for clustering in the presence of incomplete records. Our extension is called $k_m$-means and reduces to the $k$-means algorithm when all records are complete. We also provide initialization strategies for our algorithm and methods to estimate the number of groups in the dataset. Illustrations and simulations demonstrate the efficacy of our approach in a variety of settings and patterns of missing data. Our methods are also applied to the analysis of activation images obtained from a functional Magnetic Resonance Imaging experiment.

description: Abstract

Iron deficiency anemia (IDA) remains a significant public health concern, particularly among pregnant women in developing countries, where nutritional deficiencies and healthcare access limitations contribute to high prevalence rates. This study examines the risk factors associated with iron deficiency anemia among pregnant women attending SOS Hospital in Baidoa, Somalia. The research explores medical, lifestyle, and socio-economic determinants influencing anemia during pregnancy.

Using a cross-sectional study design, data was collected through structured questionnaires and interviews with pregnant women and healthcare providers. The findings indicate that poor dietary intake, frequent pregnancies, gastrointestinal disorders, and inadequate iron supplementation are key medical contributors to IDA. Socio-economic factors such as poverty, low educational levels, food insecurity, and limited access to healthcare services further exacerbate the condition. Additionally, lifestyle choices, including excessive tea or coffee consumption and heavy menstrual cycles, were identified as risk factors.

The study underscores the urgent need for targeted interventions, including improved maternal nutrition programs, iron supplementation awareness campaigns, and strengthened healthcare policies to reduce the burden of IDA. Recommendations include integrating anemia screening into routine antenatal care, enhancing community education on proper dietary practices, and ensuring equitable access to healthcare services. These findings provide valuable insights for healthcare professionals, policymakers, and organizations working to improve maternal and child health in Somalia.

description: In this work we propose a parton state as a candidate state to describe the fractional quantum Hall effect in the half-filled second Landau level. The wave function for this parton state is $\mathcal{P}_{\rm LLL} Φ_{1}^3[Φ_{2}^{*}]^{2}\simΨ^{2}_{2/3}/Φ_{1}$ and in the spherical geometry it occurs at the same flux as the anti-Pfaffian state. This state has a good overlap with the anti-Pfaffian state and with the ground state obtained by exact diagonalization, using the second Landau level Coulomb interaction pseudopotentials for an ordinary semiconductor such as GaAs. By calculating the entanglement spectrum we show that this state lies in the same phase as the anti-Pfaffian state. A major advantage of this parton state is that its wave function can be evaluated for large systems, which makes it amenable to variational calculations. In the appendix of this work we have numerically assessed the validity of another candidate state at filling factor $ν=5/2$, namely the particle-hole-symmetric Pfaffian (PH-Pfaffian) state. We find that the proposed candidate wave function for the PH-Pfaffian state is particle-hole symmetric to a high degree but it does not appear to arise as the ground state of any simple Hamiltonian with two-body interactions.

description: The application of a uniform background magnetic field makes standard quark operators utilising gauge-covariant Gaussian smearing inefficient at isolating the ground state nucleon at nontrivial field strengths. In the absence of QCD interactions, Landau modes govern the quark energy levels. There is evidence that residual Landau mode effects remain when the strong interaction is turned on. Here we introduce novel quark operators constructed from the two-dimensional $U(1)$ Laplacian eigenmodes that describe the Landau levels of a charged particle on a periodic finite lattice. These eigenmode-projected quark operators provide enhanced precision for calculating nucleon energy shifts in a magnetic field. Using asymmetric source and sink operators, we are able to encapsulate the predominant effects of both the QCD and QED interactions in the interpolating fields for the neutron. The neutron magnetic polarizability is calculated using these techniques on the $32^3 \times 64$ dynamical QCD lattices provided by the PACS-CS Collaboration. In conjunction with a chiral effective-field theory analysis, we obtain a neutron magnetic polarizability of $β^n = 2.05(25)(19) \times 10^{-4}$ fm$^3$, where the numbers in parentheses describe statistical and systematic uncertainties.

description: Imaging studies are a vital part of accurate medical care for every part of the body. Recent advances in magnetic resonance imaging (MRI) technology hold promise to uncover structural changes underlying diseases commonly considered medical mysteries. Unfortunately, the changes are often subtle, spatially distributed and complex, escaping detection by visual inspection. The key challenge is to disambiguate meaningful information from heterogeneous normal variations. The assistance of computer-aided techniques is sought to answer the following questions: are there significant morphologic differences that differentiate these patients? If so, what is the nature of these differences? Traditional computer-aided techniques that extract a set of pre-specified descriptors (i.e. volume, thickness, etc.) or compare images pixelwise can test directed hypotheses about regional differences, but do not consider important spatially diffuse effects. Furthermore, current approaches for assessing statistical differences do not allow recovery or visualization of the images underlying the associations, hindering physical interpretation. The goal of this research is to develop a new framework for automated discovery and visualization of discriminating structural markers from MRI data. We utilize the mathematics of optimal mass transport (OT) to quantify tissue spatial distribution and transform data to enhance separability of images. Our approach for Transport- Based Morphometry (TBM) defines a fully invertible transformation, allowing statistically significant discriminant differences identified in the transform domain to be visualized as morphology changes through inverse transformation. This thesis extends the mathematics of TBM to enable its first application to 3D radiology data, and applies the new TBM framework for classification and regression tasks in a variety of open clinical and research problems. Our results based on knee cartilage images indicate that TBM enables detection of osteoarthritis with 86.2% accuracy three years in advance of symptoms. TBM also enables identification of 16p11.2 duplication, deletion, and control carriers with 96% accuracy based on structural appearance of the brain alone. Patterns of injury underlying post-concussive cognitive deficits are identified with the TBM technique. The new technique also finds that aerobic fitness significantly affects brain tissue distribution in older adults. These are significant improvements over prior detection methods. Moreover, unlike previous approaches, our method allows structural markers to be visualized.

description: Extendibility of inflationary spacetimes with flat spatial geometry is investigated. We find that the past boundary of an inflationary spacetime becomes a so-called parallely propagated curvature singularity if the ratio $\dot{H}/a^2$ diverges at the boundary, where $\dot{H}$ and $a$ represent the time derivative of the Hubble parameter and the scale factor, respectively. On the other hand, if the ratio $\dot{H}/a^2$ converges, then the past boundary is regular and continuously extendible. We also develop a method to judge the continuous ($C^0$)extendibility of spacetime in the case of slow-roll inflation driven by a canonical scalar field. As applications of this method, we find that Starobinsky inflation has a $C^0$ parallely propagated curvature singularity, but a small field inflation model with a Higgs-like potential does not. We also find that an inflationary solution in a modified gravity theory with limited curvature invariants is free of such a singularity and is smoothly extendible.

description: The eigenstates of an isolated nanostructure may get mixed by the coupling to external leads. This effect is the stronger, the smaller the level splitting on the dot and the larger the broadening induced by the coupling to the leads. We describe how to calculate the nondiagonal density matrix of the nanostructure efficiently in the cotunneling regime. As an example, we consider a system of two quantum dots in the Kondo regime, the two spins coupled by an antiferromagnetic exchange interaction and each dot tunnel coupled to two leads. Calculating the nonequilibrium density matrix and the corresponding current, we demonstrate the importance of the off-diagonal terms in the presence of an applied magnetic field and a finite bias voltage.

We also study the behavior of light in the presence of plasma by considering different distributions: singular isothermal sphere, non-singular isothermal gas sphere, and plasma in a galaxy cluster. We find that the dragging of the inertial system along with the boosted parameter $Λ$ affect the value of the deflection angle. As an application, we studied the magnification for both uniform and SIS distributions.

description: Deep-sea robot operations demand a high level of safety, efficiency and reliability. As a consequence, measures within the development stage have to be implemented to extensively evaluate and benchmark system components ranging from data acquisition, perception and localization to control. We present an approach based on high-fidelity simulation that embeds spatial and environmental conditions from recorded real-world data. This simulation in the loop (SIL) methodology allows for mitigating the discrepancy between simulation and real-world conditions, e.g. regarding sensor noise. As a result, this work provides a platform to thoroughly investigate and benchmark behaviors of system components concurrently under real and simulated conditions. The conducted evaluation shows the benefit of the proposed work in tasks related to perception and self-localization under changing spatial and environmental conditions.

description: DataCrate is a specification for packaging research data for dissemination and reuse which has been presented at OR before as it developed to its current v1.0 status. This is an update on progress with the specification and tooling. The goals are of the specification are, (a) to maximise the utility of the data for researchers (including the original researchers' 'future selves') - given that a researcher has found a DataCrate package they should be able to tell what it is, how the data may be used and what all the files contain, (b) to enable discovery of the data by exposing metadata as widely as possible to both humans and machines and (c) to enable automated ingest into repositories or catalogues. DataCrate can express detailed information about which people, instruments and software were involved in capturing or creating data, where they did it and why, as well as how to cite a dataset. DataCrate draws on other standards (BagIt, JSON-LD, Schema.org) and is designed to be easy to implement.
Automated Diagnosis of Chronic Performance Problems in Production Systems

description: Large production systems are susceptible to chronic performance problems where the system still works, but with degraded performance. Chronic performance problems occur intermittently or affect a subset of end-users. Traditional approaches for diagnosis typically rely on a bottom-up approach that localizes problems by correlating low-level alarms (such as resource utilization indicators or network packet loss) across components in a production system. However, these alarm-correlation approaches fall short when diagnosing chronics because they fail to provide the necessary application-level visibility to detect chronics effectively. Due to the scale and complexity of production systems, there can be multiple unresolved chronics at any given time¶their symptoms often overlap with each other, and they are sometimes triggered by complex corner cases. This dissertation presents a top-down diagnostic framework for diagnosing chronic performance problems in production systems. The framework comprises of four components. First, an extensible log-analysis framework that extracts end-to-end causal flows using common white-box (i.e., application) logs in the production system; these end-to-end flows capture the user’s experience with the system. Second, anomaly-detection tools exploit heuristics and a peer-comparison approach to label each end-to-end flow as successful or failed. Third, a top-down statistical diagnostic tool combines white-box metrics with blackbox metrics (e.g., CPU usage) to localize the source of the problem by identifying attributes that are more correlated with failed flows than successful ones. Fourth, a visualization tool that uses peer-comparison to highlight anomalous nodes in a parallel-computing cluster. The diagnostic framework has been used to localize real incidents at an academic cloudcomputing cluster that runs the Hadoop parallel-processing framework, and a production Voice-over-IP system at a major Internet Services Provider. Our approach is not limited to these two systems and is applicable to systems such as Internet Services that serve users via independent interactions.

description: We present the first ground-based detection of sodium absorption in the transmission spectrum of an extrasolar planet. Absorption due to the atmosphere of the extrasolar planet HD189733b is detected in both lines of the NaI doublet. High spectral resolution observations were taken of eleven transits with the High Resolution Spectrograph (HRS) on the 9.2 meter Hobby-Eberly Telescope (HET). The NaI absorption in the transmission spectrum due to HD189733b is (-67.2 +/- 20.7) x 10^-5 deeper in the ``narrow'' spectral band that encompasses both lines relative to adjacent bands. The 1-sigma error includes both random and systematic errors, and the detection is >3-sigma. This amount of relative absorption in NaI for HD189733b is ~3x larger than detected for HD209458b by Charbonneau et al. (2002), and indicates these two hot-Jupiters may have significantly different atmospheric properties.

description: We compute the zero temperature dynamical structure factor $S({\bf q},ω)$ of the triangular lattice Heisenberg model (TLHM) using a Schwinger boson approach that includes the Gaussian fluctuations ($1/N$ corrections) of the saddle point solution. While the ground state of this model exhibits a well-known 120$^{\circ}$ magnetic ordering, experimental observations have revealed a strong quantum character of the excitation spectrum. We conjecture that this phenomenon arises from the proximity of the ground state of the TLHM to the quantum melting point separating the magnetically ordered and spin liquid states. Within this scenario, magnons are described as collective modes (two spinon-bound states) of a spinon condensate (Higgs phase) that spontaneously breaks the SU(2) symmetry of the TLHM. Crucial to our results is the proper account of this spontaneous symmetry breaking. The main qualitative difference relative to semi-classical treatments ($1/S$ expansion) is the presence of a high-energy spinon continuum extending up to about three times the single-magnon bandwidth. In addition, the magnitude of the ordered moment ($m=0.224$) agrees very well with numerical results and the low energy part of the single-magnon dispersion is in very good agreement with series expansions. Our results indicate that the Schwinger boson approach is an adequate starting point for describing the excitation spectrum of some magnetically ordered compounds that are near the quantum melting point separating this Higgs phase from the {\it deconfined} spin liquid state.

Thus a new kind of gauge theory is not obtained in this way, although we do find some differences in the coupling to matter. Our analysis also illuminates certain inconsistencies in previous work on this topic where a different conclusion had been reached. In particular, we show that the use of the quantum trace in defining a Yang-Mills action in this setting is not appropriate.

description: We confront observational data from gravitational wave event GW170817 with microscopic modeling of the cold neutron star equation of state. We develop and employ a Bayesian statistical framework that enables us to implement constraints on the equation of state from laboratory measurements of nuclei and state-of-the-art chiral effective field theory methods. The energy density functionals constructed from the posterior probability distributions are then used to compute consistently the neutron star equation of state from the outer crust to the inner core, assuming a composition consisting of protons, neutrons, electrons, and muons. In contrast to previous studies, we find that the 95% credibility range of predicted neutron star tidal deformabilities ($136 < Λ< 519$) for a 1.4 solar-mass neutron star is already consistent with the upper bound deduced from observations of the GW170817 event. However, we find that lower bounds on the neutron star tidal deformability will very strongly constrain microscopic models of the dense matter equation of state. We also demonstrate a strong correlation between the neutron star tidal deformability and the pressure of beta-equilibrated matter at twice saturation density.

Resummation of diagrammatic series with zero convergence radius for strongly correlated fermions

description: We demonstrate that summing up series of Feynman diagrams can yield unbiased accurate results for strongly-correlated fermions even when the convergence radius vanishes. We consider the unitary Fermi gas, a model of non-relativistic fermions in three-dimensional continuous space. Diagrams are built from partially-dressed or fully-dressed propagators of single particles and pairs. The series is resummed by a conformal-Borel transformation that incorporates the large-order behavior and the analytic structure in the Borel plane, which are found by the instanton approach. We report highly accurate numerical results for the equation of state in the normal unpolarized regime, and reconcile experimental data with the theoretically conjectured fourth virial coefficient.

description: We explore the renormalization group flow of quartic perturbations in the low-energy theory of graphene, in the strong Coulomb coupling and large-N limits, where N is the number of fermion flavors. We compute the anomalous dimensions of the quartic couplings u up to next-to-leading order in 1/N and find both relevant and irrelevant directions in the space of quartic couplings. We discuss possible phase diagrams and relevance for the physics of graphene.

description: The focus of this paper is the numerical solution of a pore-scale model for the growth of a permeable biofilm. The model includes water flux inside the biofilm, different biofilm components, and shear stress on the biofilm-water interface. To solve the resulting highly coupled system of model equations, we propose a splitting algorithm. The Arbitrary Lagrangian Eulerian (ALE) method is used to track the biofilm-water interface. Numerical simulations are performed using physical parameters from the existing literature. Our computations show the effect of biofilm permeability on the nutrient transport and on its growth.

Probing FSR star cluster candidates in bulge/disk directions with 2MASS colour-magnitude diagrams

subject: FOS: Physical sciences

description: We analyse 20 star cluster candidates projected mostly in the bulge direction ($|\ell|<60^\circ$). The sample contains all candidates in that sector classified by \citet{FSRcat} with quality flags denoting high probability of being star clusters. Bulge contamination in the colour-magnitude diagrams (CMDs) is in general important, while at lower Galactic latitudes disk stars contribute as well. Properties of the candidates are investigated with 2MASS CMDs and stellar radial density profiles (RDPs) built with field star decontaminated photometry. To uncover the nature of the structures we decontaminate the CMDs from field stars using tools that we previously developed to deal with objects in dense fields. We confirm in all cases excesses in the RDPs with respect to the background level, as expected from the method the candidates were originally selected. CMDs and RDPs taken together revealed 6 open clusters, 5 uncertain cases that require deeper observations, while 9 objects are possibly field density fluctuations.

Anisotropies in the stochastic gravitational-wave background: Formalism and the cosmic string case

description: We develop a powerful analytical formalism for calculating the energy density of the stochastic gravitational wave background, including a full description of its anisotropies. This is completely general, and can be applied to any astrophysical or cosmological source. As an example, we apply these tools to the case of a network of Nambu-Goto cosmic strings. We find that the angular spectrum of the anisotropies is relatively insensitive to the choice of model for the string network, but very sensitive to the value of the string tension $Gμ$.

CP--odd Correlation in the Decay of Neutral Higgs Boson into $ZZ$, $W^+W^-$, or $t{\bar t}$

description: We investigate the possibility of detecting CP--odd angular correlations in the various decay modes of the neutral Higgs boson including the modes of a $ZZ$ pair, a $W^+W^-$ pair, or a heavy quark pair. It is a natural way to probe the CP character of the Higgs boson once it is identified. Final state interactions (i.e. the absorptive decay amplitude) is not required in such correlations. As an illustrative example we take the fundamental source of the CP nonconservation to be in the Yukawa couplings of the Higgs boson to the heavy fermions. A similar correlation in the process $e^+e^- \to l^+ l^- H$ is also proposed. Our analysis of these correlations will be useful for experiments in future colliders such as LEP II, SSC, LHC or NLC.

description: Abstract

Iron deficiency anemia (IDA) remains a significant public health concern, particularly among pregnant women in developing countries, where nutritional deficiencies and healthcare access limitations contribute to high prevalence rates. This study examines the risk factors associated with iron deficiency anemia among pregnant women attending SOS Hospital in Baidoa, Somalia. The research explores medical, lifestyle, and socio-economic determinants influencing anemia during pregnancy.

Using a cross-sectional study design, data was collected through structured questionnaires and interviews with pregnant women and healthcare providers. The findings indicate that poor dietary intake, frequent pregnancies, gastrointestinal disorders, and inadequate iron supplementation are key medical contributors to IDA. Socio-economic factors such as poverty, low educational levels, food insecurity, and limited access to healthcare services further exacerbate the condition. Additionally, lifestyle choices, including excessive tea or coffee consumption and heavy menstrual cycles, were identified as risk factors.

The study underscores the urgent need for targeted interventions, including improved maternal nutrition programs, iron supplementation awareness campaigns, and strengthened healthcare policies to reduce the burden of IDA. Recommendations include integrating anemia screening into routine antenatal care, enhancing community education on proper dietary practices, and ensuring equitable access to healthcare services. These findings provide valuable insights for healthcare professionals, policymakers, and organizations working to improve maternal and child health in Somalia.

description: We construct an additional independent integral of motion for a class of three dimensional minimally superintegrable systems with constant magnetic field. This class was introduced in [J. Phys. A: Math. Theor. 50 (2017), 245202, 24 pages] and it is known to possess periodic closed orbits. In the present paper we demonstrate that it is maximally superintegrable. Depending on the values of the parameters of the system, the newly found integral can be of arbitrarily high polynomial order in momenta.
