description: The phenomenon of overdispersion arises when categorical or count data exhibit variability larger than expected. Multinomial data commonly demonstrate this phenomenon when the counts arise from correlated or cluster observations. There are several ways of analyzing overdispersed multinomial data. Likelihood approaches include the Dirichlet-Multinomial distribution by Mosimann (1962) and the Finite-Mixture distribution by Morel and Nagaraj (1993) and Neerchal and Morel (1998). Moment based approaches, such as Generalized Estimating Equations (GEE) by Liang and Zeger (1986) and Zeger and Liang (1986) and Quasi-Likelihood estimation by Wedderburn (1974) are also available.   The likelihood methods require full knowledge of the data generating process and are computationally intensive. The Dirichlet-Multinomial and Finite-Mixture likelihood models and their computational challenges are discussed in detail by Neerchal and Morel (2005). The moment based approaches only assume knowledge of the moment structure of the data and can be computed easily, but are less efficient than their maximum likelihood counterparts. The GEE and Quasi-Likelihood approaches only require correct specification of the first two moments. The first moment is used to obtain parameter estimates and then the variance-covariance structure is used to estimate the corresponding standard errors. The standard errors are computed either by inflating the standard errors under the assumption of independence as in the case of Quasi-Likelihood estimation, or through the use of a robust or empirical variance estimator as outlined in the GEE methodology. Although this accounts for overdispersion, we will show that these methods tend to provide inflated standard errors.  In this thesis, we present extensions of GEE which incorporate higher order moment structures. By introducing this additional information in the estimation procedure we are able to obtain estimates and standard errors that account for the overdispersion without overly inflating the standard errors. In particular, we apply this method for multinomial data and show that this estimator is more efficient than the standard GEE and Quasi-Likelihood approaches while still maintaining the computational appeal of the moment based approaches. In addition, we provide a generalized form of this estimator that has the ability to model multiple sources of correlation. We provide the asymptotic properties and several results on the efficiency of the estimators. Finally, we demonstrate these methods via simulation studies and several practical examples.

description: Proteomics is the science that deals with high-throughput analysis of proteins. The study of proteins relies on efficient protein separation technique. 2D PAGE is a powerful technique for separating complex mixtures of proteins, where thousands of proteins are separated and measured simultaneously. The analysis of 2D PAGE images needs efficient methods able to cope with large-scale dataset. Empirical Bayes methods have been shown to be very efficient at  combining information across dimensions of high-dimensional data. In the first part of this dissertation, the construction of empirical Bayes confidence intervals under different model assumptions is studied. Numerical simulations are conducted to demonstrate the satisfactory performance of the proposed methods. In the second part, a new comprehensive procedure for statistical analysis of 2D PAGE images is proposed, including protein quantification, normalization and statistical analysis. It reduces the dimension of the data. It also bypasses the current bottleneck in the analysis of 2D PAGE images in that it does not require spot matching. A strategy for multiple hypothesis testing  based on multivariate analysis combined with empirical Bayes methods is formulated and applied to the differential analysis of 2D PAGE images. The new methodologies are implemented in a custom software package.

description: We study the dynamics of a chain of coupled particles subjected to a restoring force (Klein-Gordon lattice) in the cases of either periodic or Dirichlet boundary conditions. Precisely, we prove that, when the initial data are of small amplitude and have long wavelength, the main part of the solution is interpolated by a solution of the nonlinear Schrödinger equation, which in turn has the property that its Fourier coefficients decay exponentially. The first order correction to the solution has Fourier coefficients that decay exponentially in the periodic case, but only as a power in the Dirichlet case. In particular our result allows one to explain the numerical computations of the paper \cite{BMP07}.

description: In the first part of the thesis we focus on algorithms acting in the small neighborhood of the central path. We present a new first order corrector-predictor method for solving sufficient linear complementarity problems for which a sufficiently centered feasible starting point is available. In contrast with its predictor-corrector counterpart proposed by Miao, the method does not depend on the handicap of the problem and our error estimates are sightly better. The algorithm has the same iteration complexity as Miao's method and it is quadratically convergent for problems having a strictly complementary solution. We also present an infeasible high order corrector-predictor method that is superlinearly convergent even in the absence of strict complementarity. The algorithm is globally convergent for general positive starting points and has the best known complexity. We end the first part of the thesis with a high order predictor-corrector algorithm which is better than Miao's generalization of the MTY, in the sense that if we start with a small neighborhood with the radius greater than 0.65, then the radius of the second neighborhood, in which the predicted iterate could lie, is greater than Miao's one. In the second part, two new high-order predictor-corrector and corrector-predictor methods are proposed for solving sufficient linear complementarity problems (LCP) with an infeasible starting point. Both algorithms are globally convergent for general positive starting points. These methods generate a sequence of iterates in a wide symmetric neighborhood of the central path. Both algorithms converge superlinearly to zero even for degenerate problems and have the best known iteration complexity for this type of neighborhoods. The predictor-corrector algorithm depends explicitly on the handicap of the LCP, but we also present a variant of it which does not depend on the handicap, while the corrector-predictor algorithm is independent of the handicap of the LCP.

Efficient Time Integration Methods for Stiff Stochastic Dynamical Systems

description: Dynamic systems that consist of multiple time scales where the faster time scales are stable are said to be stiff. Stiff systems pose particular challenges when it comes to numerical methods of simulation that advance the system via finite time steps. In deterministic systems modeled by ordinary differential equations (ODEs), stiff systems are well understood and efficient numerical time integration methods of such systems are available. In general implicit  methods are better suited for stiff systems while explicit methods are not. The main reason for this is that due to their better stability property the implicit methods are able to take large time steps of the order of the slowest time scales without compromising accuracy. Stiffness manifests in stochastic dynamical systems modeled by stochastic differential equations (SDEs) in a far more complex manner. Even implicit methods while stable are unable to capture the behavior accurately by taking time steps only on the order of the slowest time scale. This thesis introduces a new numerical method for stiff SDEs, called the Interlaced Euler Method, which consists of interlacing large implicit Euler time steps with a sequence of small explicit Euler time steps. It is shown that the asymptotic moment analysis applied to a suitable test problem provides the appropriate number of small explicit time steps to be used.  It is emphasized that uniform convergence with respect to the time scale separation parameter is a desirable property of a stiff solver and  it is proven that the mean and variance of the interlaced Euler method converge uniformly in the time scale separation parameter for a suitably chosen test problem. The effectiveness of this method is also illustrated via some numerical examples.

The magnetization, at low temperatures, is governed by the chain subsystem with a finite interchain coupling which leads to short range antiferromagnetic spin correlations. At higher temperatures, the response of the chains can be estimated in terms of a Curie-Weiss law. For the ladders, we apply the low-temperature approximation for a S=1/2 2-leg spin ladder by Troyer et al.

description: An algorithm has been developed for finding the global minimum of a multidimensional error function by fitting model spectral maps into observed ones. Principal component analysis is applied to reduce the dimensionality of the model and the coupling degree between the parameters, and to determine the region of the minimum. The k-nearest neighbors method is used to calculate the optimal parameter values. The algorithm is used to estimate the physical parameters of the contracting dense star-forming core of L1287. Maps in the HCO+(1-0), H13CO+(1-0), HCN(1-0), and H13CN(1-0) lines, calculated within a 1D microturbulent model, are fitted into the observed ones. Estimates are obtained for the physical parameters of the core, including the radial profiles of density ($\propto r^{-1.7}$), turbulent velocity ($\propto r^{-0.4}$), and contraction velocity ($\propto r^{-0.1}$). Confidence intervals are calculated for the parameter values. The power-law index of the contraction-velocity radial profile, considering the determination error, is lower in absolute terms than the expected one in the case of gas collapse onto the protostar in free fall. This result can serve as an argument in favor of a global contraction model for the L1287 core.

Effects of Spatial and Temporal Correlation in General Linear Modeling of fMRI
Creators: name: Sgambati, Francis Patrick
Publisher: name: Maryland Shared Open Access Repository
Year: 2010

description: Current functional magnetic resonance imaging (fMRI) analysis utilizes a false discover rate (FDR) based on the assumption of independent voxels. Our fMRI general linear model simulation accurately portrays the expected FDR. We hypothesis that spatial and temporal correlation reduces the sensitivity of the analysis.  Moreover, the FDR methods become ineffective in properly diagnosing fMRI results.  We compared our model with no correlation to assess the effects of various levels of temporal and spatial correlation. Low levels of correlation that have very minimal changes in the simulated hemodynamic response function (HRF) produced similar expected results from using a FDR. High levels of correlations, levels that are realistic variations, produce results that undermine the effectiveness of using the FDR. An increased temporal and spatially correlation of fMRI HRFs reduces the validity of the expected FDR approaches. fMRI image analysis should account for repeated stimulus and adjacent brain activity.

description: Schizophrenia is a debilitating mental disorder affecting approximately 1% of the global population characterized by the presence of hallucinations, delusions and formal thought disorder.  Although the etiology remains unknown several brain regions have been implicated in the disease, including the striatum.  The striatum is composed of the caudate and putamen which modulate cognitive, emotional and motor behavior, all of which are abnormal in patients with schizophrenia (SZs).  Regional cerebral blood flow studies have shown that striatal glucose metabolism is decreased in these patients and normalized with the administration of antipsychotic drugs (APDs) but only when symptoms improve.  Additionally, methamphetamines, often used as a rat model for schizophrenia, have been shown to cause a decrease in mitochondrial function which is also normalized by APDs.  This suggests that there is an altered metabolism in SZs that could result from abnormalities in mitochondria, the energy producing organelles in the cell. APDs could normalize striatal metabolism by altering the number and/or the function of mitochondria.  This dissertation test these hypotheses by using stereology to analyze electron micrographs and compare mitochondrial number in the striatum of human postmortem tissue from SZs on and off antipsychotic drugs to normal controls. Because schizophrenia is very heterogeneous both in symptomolgy and etiology, the difference in mitochondrial number was also analyzed within the different subtypes of schizophrenia which are grouped based on common symptomology. The results indicate a significant decrease in the number of mitochondria in axon terminals forming synapses in the putamen of SZs on typical APDs, particularly if they respond to treatment. Also, SZs  with a paranoid diagnosis had significantly fewer mitochondria than SZs with a chronic undifferentiated  (CUT) subtype.  Mitochondrial function was measured using cytochrome oxidase (COX), a component of complex IV of the electron transport chain.  COX was decreased in the putamen of SZs.  APDs chronically administered to normal rats had no effect on mitochondrial number in the striatum but did significantly increase COX staining.  It is concluded from this study that there are abnormalities in the mitochondria in SZs that can be altered by APD administration.

title: Designing a cased based reasoning decision support system for ice management operations using expert knowledge
Creators: name: Yazdanpanah, Fatemeh
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Prevention of safety hazards plays an important role in the offshore and maritime industries, especially in offshore ice management operations as the safety of these operations depends on the judgment and decision making of experienced captains and their bridge teams. To address safety challenges that may arise in the context of ice management operations, this study focused on a human-centered approach to develop an early-stage decision support system (DSS) for offshore ice management operations by applying a case-based reasoning (CBR) method. The aim of this research is to (i) capture knowledge from expert seafarers to be used in the development of a DSS; and (ii) propose a DSS employing a CBR model to be used onboard ships in a real-time basis for ice management operations. To capture seafarers’ experience, this study employed semi-structured interviews and bridge simulator exercises. The results of the knowledge capture exercises were translated into an ice management DSS using a CBR model. The case-based reasoning (CBR) model develops solutions to new problems by using similar problems in the past. The DSS employs a decision tree algorithm to retrieve a case to match observations from the current situation with an unknown outcome to a case base with known outcomes. This thesis describes the methods used in the development of the onboard DSS to provide tactical guidance for ice management operations. It also outlines the methods used to test the DSS software’s suggested ice management strategies and adjustments during a series of simulator exercises.

description: Passenger trains represent a challenging environment in emergencies, with specific evacuation conditions resulting from the typical layout and interior design inherent to public transportation vehicles. This paper describes a dataset obtained in a full-scale controlled experiment emulating the emergency evacuation of a double-deck electric unit railcar carried out in Prague in 2018. 15 evacuation trials involving 91 participants were conducted under various evacuation scenarios considering different compositions of passenger crowd, exit widths, and exit types (e.g. egress to a high platform, to an open rail line using stairs, and a 750 mm jump without any supporting equipment). The study's main goals were to collect experimental data on the movement conditions in the railcar and to study the impact of various boundary conditions on evacuation process and total evacuation time. Movement characteristics (exit flows, speeds) and human behaviour (pre-movement activities, exiting behaviours) were also analysed. The data obtained was used to validate and adjust a Pathfinder model to capture important aspects of evacuation from the railcar. Furthermore, a series of simulations using this model was performed to provide sensitivity analysis of the influence of crowd composition, exit width, and exit type on total evacuation time. As a key finding, we can conclude that for the case of a standard exit path (platform or stairs) the width of the main exit had the greatest impact on total evacuation time, however, crowd composition played the prevailing role in evacuation scenarios involving a jump.

description: Accretion processes in quasars and active galactic nuclei are still poorly understood, especially as far as the connection between observed spectral properties and physical parameters is concerned. Quasars show an additional degree of complexity compared to stars that is related to anisotropic emission/obscuration influencing the observed properties in most spectral ranges. This complicating factor has hampered efforts to define the equivalent of an Hertzsprung-Russel diagram for quasars. Even if it has recently become possible to estimate black hole mass and Eddington ratio for sources using optical and UV broad emission lines, the results are still plagued by large uncertainties. Nevertheless, robust trends are emerging from multivariate analysis of large spectral datasets of quasars. A firm observational basis is being laid out by accurate measurements of broad emission line properties especially when the source rest-frame is known. We consider the most widely discussed correlations (i.e. the so-called "eigenvector 1 parameter space" and the "Baldwin effect") and analyze how they can be explained in terms of accretion properties, broad line region structure, and source evolution. We critically review recent estimates of black hole mass, accretion rate, spin and possible orientation indicators, stressing that any improvement in these parameters will provide a much better understanding of the physics and dynamics of the region producing the optical and UV broad emission lines. More accurate measurements of Eddington ratio and black hole mass may have a significant impact on our ideas about evolution of quasar properties with redshift and luminosity as well as on broader cosmological issues.

description: Fast radio bursts (FRBs) are extragalactic astrophysical transients whose brightness requires emitters that are highly energetic, yet compact enough to produce the short, millisecond-duration bursts. FRBs have thus far been detected between 300 MHz and 8 GHz, but lower-frequency emission has remained elusive. A subset of FRBs is known to repeat, and one of those sources, FRB 20180916B, does so with a 16.3 day activity period. Using simultaneous Apertif and LOFAR data, we show that FRB 20180916B emits down to 120 MHz, and that its activity window is both narrower and earlier at higher frequencies. Binary wind interaction models predict a narrower periodic activity window at lower frequencies, which is the opposite of our observations. Our detections establish that low-frequency FRB emission can escape the local medium. For bursts of the same fluence, FRB 20180916B is more active below 200 MHz than at 1.4 GHz. Combining our results with previous upper-limits on the all-sky FRB rate at 150 MHz, we find that there are 3-450 FRBs/sky/day above 50 Jy ms at 90% confidence. We are able to rule out the scenario in which companion winds cause FRB periodicity. We also demonstrate that some FRBs live in clean environments that do not absorb or scatter low-frequency radiation.

The classical approach based on cross-correlations of binned light curves ignores the Poisson nature of the time-series data, and is unable to model the full complexity of the problem. Aims. To present a statistically proper and robust GRB timing/triangulation algorithm as a modern update to the original procedures used for the Interplanetary Network (IPN). Methods. A hierarchical Bayesian forward model for the unknown temporal signal evolution is learned via random Fourier features (RFF) and fitted to each detector's time-series data with time-differences that correspond to GRB's position on the sky via the appropriate Poisson likelihood. Results. Our novel method can robustly estimate the position of a GRB as verified via simulations. The uncertainties generated by the method are robust and in many cases more precise compared to the classical method. Thus, we have a method that can become a valuable tool for gravitational wave follow-up. All software and analysis scripts are made publicly available here (https://github.com/grburgess/nazgul) for the purpose of replication.

description: Spatially-resolved velocity maps at high resolutions of 1-10 pc are becoming available for many nearby AGNs in both optical/infrared atomic emission lines and sub-mm molecular lines. For the former, it has been known that a linear relationship appears to exist between the velocity of the ionized gas clouds and the distance from the nucleus in the inner ~100 pc region, where these clouds are outflowing. Here we demonstrate that, in such a case, we can actually derive the three-dimensional (3D) geometrical distribution of the clouds directly from the velocity map. Revisiting such a velocity map taken by HST for the prototypical Type 2 AGN NGC1068, we implement the visualization of the 3D distribution derived from the map, and show that this inner narrow-line region has indeed a hollow-cone structure, consistent with previous modeling results. Quite possibly, this is the outer extended part of the polar elongated dusty material seen in the recent mid-IR interferometry at pc scale. Conversely, the latter small-scale geometry is inferred to have a hollow-cone outflowing structure as the inward extension of the derived 3D distribution above. The AGN obscuring "torus" is argued to be the inner optically thick part of this hollow-cone outflow, and its shadowed side would probably be associated with the molecular outflow seen in certain sub-mm lines. We discuss the nature of the linear velocity field, which could be from an episodic acceleration that had occurred ~10^5 years ago.

description: We have trapped rubidium atoms in the magnetic field produced by a superconducting atom chip operated at liquid Helium temperatures. Up to $8.2\cdot 10^5$ atoms are held in a Ioffe-Pritchard trap at a distance of 440 $μ$m from the chip surface, with a temperature of 40 $μ$K. The trap lifetime reaches 115 s at low atomic densities. These results open the way to the exploration of atom--surface interactions and coherent atomic transport in a superconducting environment, whose properties are radically different from normal metals at room temperature.

description: The nature of the magnetic coupling between T Tauri stars and their disks determines not only the mass accretion process but possibly the spin evolution of the central star. We have taken a recently-published surface magnetogram of one moderately-accreting T Tauri star (V2129 Oph) and used it to extrapolate the geometry of its large-scale field. We determine the structure of the open (wind-bearing) field lines, the closed (X-ray bright) field lines and those potentially accreting field lines that pass through the equatorial plane inside the Keplerian co-rotation radius. We consider a series of models in which the stellar magnetic field is opened up by the outward pressure of the hot coronal gas at a range of radii. As this radius is increased, accretion takes place along simpler field structures and impacts on fewer sites at the stellar surface. This is consistent with the observed variation in the Ca II IRT and HeI lines which suggests that accretion in the visible hemisphere is confined to a single high-latitude spot. By determining the density and velocity of the accretion flows, we find that in order to have most of the total mass accretion rate impacting on a single high-latitude region we need disk material to accrete from approximately 7R*, close to the Keplerian co-rotation radius at 6.8R*. We also calculate the coronal density and X-ray emission measure. We find that both the magnitude and rotational modulation of the emission measure increase as the source surface is increased. For the field structure of V2129 Oph which is dominantly octupolar, the emission forms a bright, high-latitude ring that is always in view as the star rotates. Since the accretion funnels are not dense enough to cause significant scattering of coronal X-ray photons, they provide only a low rotational modulation of around 10% at most.

description: In this paper we present a method to identify people by means of thermal (TH) and visible (VIS) hand images acquired simultaneously with a TESTO 882-3 camera. In addition, we also present a new database specially acquired for this work. The real challenge when dealing with TH images is the cold finger areas, which can be confused with the acquisition surface. This problem is solved by taking advantage of the VIS information. We have performed different tests to show how TH and VIS images work in identification problems. Experimental results reveal that TH hand image is as suitable for biometric recognition systems as VIS hand images, and better results are obtained when combining this information. A Biometric Dispersion Matcher has been used as a feature vector dimensionality reduction technique as well as a classification task. Its selection criteria helps to reduce the length of the vectors used to perform identification up to a hundred measurements. Identification rates reach a maximum value of 98.3% under these conditions, when using a database of 104 people.
