Abstract:
Clostridium difficile, the primary cause of nosocomial diarrhea in the United States and many other industrialized countries, is recognized as a major health concern because of its ability to cause severe intestinal disease leading to complications such as relapses and infections due to vancomycin-resistant enterococci. The disease results from two toxins, toxins A and B, produced by this pathogen. In this study, we evaluated the TOX A/B TEST, a new 1-h enzyme immunoassay (EIA) that detects toxins A and B. We compared the test with the tissue culture assay, which is recognized as the “gold standard” forC. difficile testing. Evaluations were performed in-house at TechLab, Inc. (Blacksburg, Va.) and off-site at four clinical laboratories. Of 1,152 specimens tested, 165 were positive by the TOX A/B TEST and tissue culture and 973 were negative by both tests. The sensitivity and specificity were 92.2 and 100%, respectively. The positive and negative predictive values were 100 and 98.6%, respectively, and the correlation of the TOX A/B TEST with tissue culture was 98.8%. When discrepant samples were resolved by culture, the sensitivity and specificity were 93.2 and 98.9%, respectively. The positive and negative predictive values were 100 and 98.8%, respectively, with a correlation of 99.0%. There were no specimens that were positive by the TOX A/B TEST and negative by tissue culture. Fourteen specimens were negative by the TOX A/B TEST but positive by tissue culture. Of these, two were negative by toxigenic culture, five were positive by toxigenic culture, and seven were not available for further testing. There were no indeterminate results, since the test does not have an indeterminant zone. In a separate study, 102 specimens that were positive by tissue culture and the TOX A/B TEST were examined in toxin A-specific EIAs. Two specimens that presumptively contained toxin A-negative, toxin B-positive (toxA−/toxB+) isolates were identified. One specimen was from a patient with a clinical history consistent with C. difficile infection. Isolates obtained from these specimens by selective culture on solid media and in broth tested toxA−/toxB+ when grown in brain heart infusion dialysis flasks, which stimulate in vitro production of both toxins. Our findings show that the TOX A/B TEST is suitable as a diagnostic aid for C. difficile disease because it correlates well with tissue culture and detects isolates that may be missed with toxin A-specific EIAs.

Abstract:
This study examined the utility of the Trail Making Test Quotient (Trails B/ Trails A) in assessing executive functioning relative to that of common tests of executive function such as the Wisconsin Card Sorting Test, Category Test, and the Stroop Test. The purpose of the current study was to investigate the relationship of the Trail Making Test Quotient (Trails B/ Trails A) with other common tests of executive functioning (i.e., Wisconsin Card Sorting Test, Stroop, Category Test) to determine whether these tests are measuring similar domains of functioning or whether Trail Making Test Quotient (Trails B/ Trails A) offers a more pure measure of executive functioning over and beyond that of Trail Making Test B alone or the difference score, Trail Making Test (Trails B- Trails A). A series of partial correlations were conducted involving the Trail Making Test scores (Quotient, Difference, and B [Raw]), and the scores of the executive functioning measures (Wisconsin Card Sorting Test, Category Test, and Stroop), controlling for age, education, and gender. Trails Quotient, Trails B Raw, and Trails Difference were found to significantly negatively correlate with WCST Total # of Categories. Only Trails B Raw and Trails Difference were found to significantly positively correlate with WCST Perseverative Responses and Category Error. None of the Trail Making Test measures used in this study were found to significantly correlate Stroop Interference. Correlation coefficients were compared to determine the strength of Trails Quotient's relationship with the aforementioned executive functioning measures relative to that of Trails Difference and Trails B Raw. Contrary to the hypotheses of the current study, the Trails Quotient demonstrated a significantly weaker correlation with WCST Total # of Categories, WCST Perseverative Responses, and Category Error than that of Trails Difference and Trails B Raw. Additionally, there were no significant differences in the correlation coefficients of Trails Quotient, Trails Difference, and Trails B Raw with Stroop Interference. However, upon further investigation using exploratory factor analyses, it was discovered that Trails Quotient may have represented a particular component of executive functioning more so than the Trails Difference and Trails B Raw. The results suggest that Trails Quotient offers a unique estimate of executive skill specific to cognitive organization, whereas Trails B Raw and Trails Difference represent multiple executive domains including regulatory and organizational abilities. Clinical practice will benefit from the current study's findings in that assessment of complex executive functioning will be more precise. Future research is needed to determine the utility of the Trails Quotient in identifying specific types and locations of brain injury. Assessment of specific impaired frontal skills common to degenerative dementias and traumatic brain injury may be possible with the use of Trails Quotient contingent upon further research. Future research into the domains of executive functioning and the Trail Making Test should focus on specific skills within regulatory and organizational components, and the development of normative data for Trails Quotient.

Abstract:
This paper sets out to examine the most common errors in the national test and whether the students make the same errors in English course B as in English course A at Upper Secondary School in Sweden. The method used for this study is quantitative where nine grammatical features are used to count the errors made. Twenty national tests were used to carry out this study; ten national tests are from English course A and the other ten from English course B. Results from all features from English course A are compared with some features from English course B. The results show that the most common errors made in the national test are subject verb agreement and tense. Those two features had also a worsening in the English course B. The genitive errors have also doubled in English course B. The best improvement happened with the capital letters. Other features either stayed the same or improved slightly. One of the solutions for grammatical errors could be that teachers and students pay more attention to it and that the teachers include more grammar in their lessons so that the students have an opportunity to improve.

Full text
Abstract:
Recently the radiative B-decay to strange axial-vector mesons, B--> K1(1270) gamma, was observed with a rather large branching ratio. This process is particularly interesting as the subsequent K1-decay into its three-body final state allows us to determine the polarization of the photon, which is mostly left(right)-handed for Bbar(B) in the Standard Model while various new physics models predict additional right(left)-handed components. In this thesis, a new method is proposed to determine the polarization, exploiting the full Dalitz plot distribution, which seems to reduce significantly the statistical errors on the polarization parameter lambda_gamma measurement.This polarization measurement requires, however a detailed knowledge of the K1--> K pi pi strong interaction decays, namely, the complex pattern of the various partial wave amplitudes into several possible quasi-two-body channels as well as their relative phases. A number of experiments have been done to extract all these information while there remain various problems in the previous studies. In this thesis, we investigate the details of these problems. As a theoretical tool, we use the 3P0 quark-pair-creation model in order to improve our understanding of strong K1 decays.Finally we try to estimate some theoretical uncertainties: in particular, the one coming from the uncertainty on the K1 mixing angle, and the effect of a possible ''off-set'' phase in strong decay S-waves. According to our estimations, the systematic errors are found to be of the order of sigma(lambda_gamma)^th<20%. On the other hand, we discuss the sensitivity of the future experiments, namely the SuperB factories and LHCb, to lambda_gamma. Naively estimating the annual signal yields, we found the statistical error of the new method to be sigma(lambda_gamma)^stat<10% which turns out to be reduced by a factor 2 with respect to using the simple angular distribution.We also discuss a comparison to the other methods of the polarization measurement using processes, such as B--> K* e^+ e^-, Bd--> K* gamma and Bs--> phi gamma, for the determination of the ratio of the Wilson coefficients C7gamma^'eff/C7gamma^eff. We show an example of the potential constraints on C7gamma^'eff/C7gamma^eff. in several scenarios of supersymmetric models.

Abstract:
This study is about the selection of test groups for a user test. The natural choice for company is to choose people that are included in the target group for the product or system that are about to be tested. This is something I have chosen to focus on. Is there reason to believe that you would choose people to your test group that are not part of the target audience and still produce an equally good result? To learn more about this, a test is conducted on a product that has one focus area and a clear target audience, in this case Snapchat. This research is showing that it’s a difference depending on what people are picked for the test. The two different groups focused on different things in the test that gave different goals to follow.

Abstract:
Le fil directeur de cette thèse est l'étude de mécanismes de décision automatique utilisant des données recueillies en interagissant avec des agents stratégiques ou non-stratégiques. Dans la première partie, nous nous intéressons à l'un des problèmes fondateur de la théorie des mécanismes d'incitation, l'apprentissage de l'enchère maximisant le revenu du vendeur. Cette théorie suppose l'existence d'une distribution de valeur qui permet au vendeur d'optimiser son mécanisme. Pour estimer cette distribution de valeur, les vendeurs utilisent en pratique pour la plupart la distribution des enchères passées des différents acheteurs. En considérant cette hypothèse, nous prouvons qu'il existe des stratégie simples qui permettent aux acheteurs d'augmenter très fortement leur utilité si le vendeur utilise ses enchères passées pour optimiser son mécanisme. Nous commençons par une étude détaillée des principaux résultats de la littérature des enchères. Nous introduisons une forme variationnelle qui permet à la fois de calculer analytiquement des équilibres de Nash mais aussi de mettre en place des méthodes numériques. Nous prouvons que notre approche est robuste par rapport au nombre d'exemples accessibles au vendeur et à une connaissance partielle de la distribution de la compétition. Notre approche numérique nous permet de considérer d'autres configurations plus complexes comme les enchères simultanées de plusieurs objets. Nos travaux sont une nouvelle contribution à l'ensemble des recherches récentes qui s'intéressent à comment certains résultats à la frontière entre la théorie des jeux et l'économie doivent être repensés au moment où des algorithmes d'apprentissage statistique sont utilisés pour exploiter la masse de données disponibles sur la plupart des grandes plateformes internet. Dans la seconde partie, indépendante de la première, nous nous intéressons à ce qu'il est possible de faire pour un agent qui a accès à des données qui n'ont pas été manipulées par un agent stratégique, comme dans un essai clinique par exemple. Nous introduisons un nouvel algorithme qui permet d'arbitrer entre la longueur et le coût d'un A/B test ou de toute expérimentation statistique. Lorsque l'expérimentateur a accès à des données récoltées de façon aléatoire, il est aussi capable de faire des raisonnements contrefactuels. Nous étudions les différents estimateurs qui permettent de faire ce type de raisonnement et proposons un nouvel estimateur plus adapté à l'étude des systèmes de recommandations. Cette seconde partie se concentre sur certains des principaux outils statistiques aujourd'hui utilisés pour mettre en place des systèmes automatisés de prises de décisions
The common thread of this manuscript is the study of some of the main automatic decision processes using data provided by either strategic or non-strategic agents. In the first part of the manuscript, we study the learning of revenue-maximizing auctions on data provided by the bidders. We first introduce this framework by a detailed overview of the classical results of the auction literature. We prove that if one bidder is aware that his bid distribution is used in order to optimize the seller's revenue, he can take advantage of this data-driven mechanism and increase his utility. To do so, we introduce a simple and generic variational approach to design novel bidding strategies. This strategy works with general value distributions, with asymmetric bidders and for different revenue-maximizing mechanisms. Furthermore, it can be made robust to sample approximation errors on the seller part. This results in a large increase in utility for bidders whether they have a full or partial knowledge of their competitors. This approach naturally yields itself to numerical optimization and algorithms for designing the strategies. We show that these algorithms can be extended to tackle more complicated setups such as the multi-item setting, where no analytical solutions are known. We also study the economical consequences of the existence of such shading strategies on recent results on collusion in revenue-maximizing auctions. This represents a new contribution to the recent line of research at the frontier of game theory, economics and statistics showing how the use of modern statistical learning algorithms on the large amount of data available on internet platforms modifies classical economics interactions.In the second part of the manuscript, we study practical decisions processes enabling to take informed decisions when data are provided by non-strategic agents. We focus on the A/B testing setting where an agent needs to choose between two alternatives. We introduce a new algorithm interpolating between two classical objectives of the multi-armed bandit literature: regret minimization and best-arm identification. Finally, we study some of the main counterfactual estimators used by practitioners when they have access to randomized data. We provide a large overview of most of these estimators, exhibit some of their theoretical properties, their interest in practice and some of their main limitations. This second part provides a large overview of practical statistical tools that can be be used in modern industrial applications

Abstract:

Beauty quarks are pair-produced by strong interactions in multi-TeV proton-proton (pp) collisions at the CERN Large Hadron Collider (LHC). Such interactions allow for a test of perturbative Quantum Chromodynamics (QCD) in a new energy regime. The primary beauty-antibeauty quark b b pair production mechanisms in perturbative QCD are referred to as flavor creation, flavor excitation, and gluon splitting. These three mechanisms produce bb pairs with characteristic kinematic behavior, which contribute differently to the shape of the differential b b production cross section with respect to the difference in the azimuthal angle Δ&phis; and the combined separation variable Δ R = [special characters omitted] between the beauty and antibeauty quarks (b and b, respectively); with Δη being the change in the pseudorapidity η = — ln (tan (&thetas;/2)), &thetas; being the polar angle. These Δ&phis; and ΔR variables are collectively referred to as angular correlation variables and hence forth referred to as Δ A. By measuring the shape and absolute normalization of the differential production cross section distributions with respect to ΔA a test of the predictions of perturbative QCD can be performed.

This dissertation describes a measurement of the differential production cross sections with respect to the ΔA between two hadronic jets arising from the hadronization and decay of b or b (referred to as b hence forth) produced in pp collisions at the LHC observed with the Compact Muon Solenoid (CMS) detector. Hadronic jets are identified as originating from b quarks, i.e. b-tagged, based on the presence of high impact parameter tracks with respect to the primary pp interaction point in events in which a muon is also produced. The study presented in this dissertation corresponds to an integrated luminosity of 3 pb -1 collected in 2010 by the CMS experiment at a center-of-mass energy of 7 TeV.

The visible kinematic phase-space of the differential production cross sections probed in this study is given by the requirement of two b-tagged hadronic jets with [special characters omitted] > 30 GeV and ∥ηjet∥ < 2.4, with an angular separation of ΔR > 0.6 between them, one of these jets has a muon within its constituents with [special characters omitted] > 8 GeV and ∥ημ∥ < 2.1. The results obtained in data are compared with predictions based on perturbative QCD calculations given by CASCADE, MADGRAPH/MADEVENT, and PYTHIA Monte Carlo event generators. The predictions of perturbative QCD are found to be in agreement the measured differential cross sections within uncertainties.

Abstract:
AbstractThe term ‘cognitive structures’ is used to describe the fact that mental models underlie thinking, reasoning and representing. Cognitive structures generally improve the efficiency of information processing by providing a situational framework within which there are parameters governing the nature and timing of information and appropriate responses can be anticipated. Unanticipated events that violate the parameters of the cognitive structure require the cognitive model to be updated, but this comes at an efficiency cost. In reversal learning a response that had been reinforced is no longer reinforced, while an alternative is now reinforced, having previously not been (A+/B− becomes A−/B+). Unanticipated changes of contingencies require that cognitive structures are updated. In this study, we examined the effect of lesions of the orbital frontal cortex (OFC) and the effects of the selective serotonin reuptake inhibitor (SSRI), escitalopram, on discrimination and reversal learning. Escitalopram was without effect in intact rats. Rats with OFC lesions had selective impairment of reversal learning, which was ameliorated by escitalopram. We conclude that reversal learning in OFC-lesioned rats is an easily administered and sensitive test that can detect effects of serotonergic modulation on cognitive structures that are involved in behavioural flexibility.

Abstract:
AbstractDeep Neural Networks (DNNs) are being deployed in a wide range of settings today, from safety-critical applications like autonomous driving to commercial applications involving image classifications. However, recent research has shown that DNNs can be brittle to even slight variations of the input data. Therefore, rigorous testing of DNNs has gained widespread attention.While DNN robustness under norm-bound perturbation got significant attention over the past few years, our knowledge is still limited when natural variants of the input images come. These natural variants, e.g., a rotated or a rainy version of the original input, are especially concerning as they can occur naturally in the field without any active adversary and may lead to undesirable consequences. Thus, it is important to identify the inputs whose small variations may lead to erroneous DNN behaviors. The very few studies that looked at DNN’s robustness under natural variants, however, focus on estimating the overall robustness of DNNs across all the test data rather than localizing such error-producing points. This work aims to bridge this gap.To this end, we study the local per-input robustness properties of the DNNs and leverage those properties to build a white-box (DeepRobust-W) and a black-box (DeepRobust-B) tool to automatically identify the non-robust points. Our evaluation of these methods on three DNN models spanning three widely used image classification datasets shows that they are effective in flagging points of poor robustness. In particular, DeepRobust-W and DeepRobust-B are able to achieve an F1 score of up to 91.4% and 99.1%, respectively. We further show that DeepRobust-W can be applied to a regression problem in a domain beyond image classification. Our evaluation on three self-driving car models demonstrates that DeepRobust-W is effective in identifying points of poor robustness with F1 score up to 78.9%.

Abstract:
AbstractChapter 7 explained the detection and hypothesis testing problems, Huffman codes and the situation where errors are independent and Gaussian. In this chapter, we prove the optimality of the Huffman code in Sect. 8.1 and the Neyman–Pearson Theorem in Sect. 8.2. Section 8.3 discusses the theory of jointly Gaussian random variables that is used to analyze the modulation schemes of Sect. 7.5 . Section 8.4 uses the results on jointly Gaussian random variables to explain hypothesis tests that arise when analyzing data. That section discusses the chi-squared test and the F-test. Section 8.5 is devoted to the LDPC codes that are widely used in high-speed communication links. These codes augment a group of bits to be transmitted over a noisy channel with additional bits computed from those in the group. When it receives the bits, when the augmented bits are not consistent, the receiver attempts to determine the bits that are most likely to have been corrupted by noise.
