A Sleep Staging Method Based on Single Channel EOG Signal

Wang, Wen-yen 15 July 2009 (has links)
Sleep Recording is important for clinical diagnosis and treatment of sleep disorders. Sleep staging is one of the most important steps in sleep analysis and is typically performed based on the characteristics of electrophysiological signals including EEG, EOG, and EMG. Normal healthy sleep consists of sequences of stages. According to the traditional Rechtschaffen & Kales (R&K) rules, these stages include: Awake, Light Sleep, Deep Sleep, and Rapid-Eye Movement (REM) Sleep. Our study develops a simple four-stage process to classify sleep into wakefulness, stage 1, stage 2, slow wave sleep (SWS) and rapid eye movement (REM) sleep based on single LEOG channel. To achieve this goal, this study first generates feature variables from LEOG signal. The proposed feature selection method is applied to select a subset of features to improve the accuracy of the classifier. By applying the proposed approach to 48727 distinct LEOG epochs that are obtained from 62 subjects, the accuracy rate is about 72.6%. The largest amount of errors occurs in the identification of Stage 1, 56.3% of which was misclassified into stages 2 or wake. The second largest error is associated with REM sleep, 23.7% of which was misclassified into stages 2.

Venous perfusion and intravenous dissection for fixation, evaluation and staging of renal tumours in nephrectomy specimens

Bergen, Rebecca 15 September 2011 (has links)
Invasion of renal cell carcinoma into the renal vein has a detrimental effect on the prognosis as this is an important tumour dissemination route. Determination of renal vein invasion is vital to accurate pathological staging. The purpose of this study is to determine if perfusing with formalin and probing the veins of radical nephrectomy specimens allows for easier visualization of the veins and an improved diagnosis of vascular invasion. In this study, 28 radical nephrectomy specimens were examined using renal vein probing and perfusion techniques. The tumours were segregated based on size, Fuhrman grade and tumour type. Comparison of the study tumours versus renal tumours examined in 2009 that were not perfused and probed were based on these groupings. There was a trend to identifying more renal vein invasion, especially for tumours 4.1 to 7.0 cm in diameter, but this did not result in statistical significance in this small study group.

Essays on venture capital market and exit stage / Essais sur le marché du capital risque et la phase de sortie

El Bouzaidi, Saloua 26 September 2014 (has links)
Cette thèse poursuit quatre objectifs de recherche, leur combinaison à pour but de contribuer à la compréhension du fonctionnement du marché du capital risque (CR). Le premier objectif est de fournir une synthèse de la littérature sur l'étape de sortie du capital risque. Le survey commence par décrire le processus de financement par CR en soulignant comment le fonctionnement de l'industrie permet de gérer l'asymétrie d'information entre l'entrepreneur et l'investisseur de CR. Le survey met également en évidence la position centrale de l'étage de sortie dans le cycle de financement par CR. En effet, les entreprises de capital-risque sont gérées par des professionnels qui fournissent des capitaux et des compétences aux entreprises entrepreneuriales.Généralement, les entreprises de portefeuille ne paient pas des dividendes, et les rendements générés par l'investissement sont réalisées par l'intermédiaire d'un événement de sortie, indiquant qu'une sortie rentable est au cœur de l'industrie du capital de risque. Le survey met notamment l'accent sur les déterminants de la phase de sortie, et examine comment le choix de sortie peut varier en fonction des objectifs du capital-risqueur et de l'entrepreneur. La question de recherche du premier chapitre empirique porte sur l'effet concurrentiel de financement par capital risque dans les introductions en bourse. Deux hypothèses sous-tendent cette étude. Tout d'abord, si les annonces de cotation en bourse révèlent de précieux renseignements sur les entreprises introduites, il est probable que les investisseurs des entreprises concurrentes utilisent cette information pour réévaluer la valeur et les perspectives d'évolution de leurs propres entreprises. Par conséquent, les annonces d'introduction en bourse sont susceptibles d'avoir des effets d'externalité sur les entreprises rivales. Deuxièmement, si les investisseurs de capital-risque sont considérés comme ayant un rôle en aidant leurs entreprises à traiter avec le marché public, il est probable que les concurrents réagissent différemment aux introductions en bourse des entreprises soutenues par CR. En conséquence, les deux questions de recherche suivantes ont été formulées: (1) quelle est la réaction des concurrents à l'annonce d'introductions en bourse? Et (2) la réaction des concurrents diffère-t-elle en fonction du statut des entreprises émises? En accord avec la littérature, les résultats montrent qu'en France, les introductions en bourse d'entreprises sans financement de CR créent une réaction négative à l'égard des concurrents opérant dans le même secteur d'activité. Ce qui suggère que les entreprises introduites seront en mesure d'améliorer leur position concurrentielle. D'une manière différente, l'introduction en bourse d'entreprise financée par CR a un effet d'annonce positive sur le rendement boursier de ses concurrents. Ce résultat suggère que le marché public considère l'introduction en bourse d'entreprises soutenues par CR comme un signal positif sur les perspectives de l'ensemble de marché, dont les concurrents peuvent également tirer profit. En fait, cette relation positive suggère que les IPOs d'entreprises financées par CR signalent des conditions positives du marché. Conférant ainsi aux investisseurs de capital-risque un pouvoir de prévoyance, où le capital-risqueur décidera de coter son entreprise quand la valorisation du marché boursier est élevée... / This thesis pursues four primary research objectives, its combination aim to contribute to the understanding of venture capital (VC) market functioning.The first objective is to provide a literature-based summary about venture capital exit stage.The survey starts by describing VC financing process and highlighting how the industry functioning allow managing the information symmetry between the entrepreneur and the VC investor. In fact, venture capitalists invest in young growing firms having little historical data and collateral. VC investors direct monitoring, contracting conditions and staging decisions aim to reduce this information asymmetry risk. The survey also highlights the central position of the exit stage in the VC financing cycle. In fact, Venture capital firms are managed by professionals that provide capital and competences to entrepreneurial firms. The investee firms typically do not pay dividends, and the returns generated by the VC investment are realized via an exit event, indicating that a protable exit lies at the heart of venture capital industry.The main objective of the survey is to emphasize the determinant of the exit stage, and to discuss how the exit choice may differ depending on the venture capitalist and the entrepreneur objectives. For instance, the entrepreneur private benefit of control for being the manager of a standalone firm promotes him to favorite an IPO exit. However, the locks up period associated with IPOs don’t allow the venture capitalist to divest their total holding immediately after an IPO exit. Therefore, and giving the limited life span of VC funds, venture capitalist preferred exits routes are those associated with immediate divestment. Suggesting that in addition to the firm characteristics and market conditions, the entrepreneur and the venture capitalist objectives are also important for the exit route choice. For instance, VC investors’ incentives may encourage more rapid and less protable acquisitions of their backed firms and therefore higher acquirers' wealth gains. In fact, VC funds approaching maturity need to be liquidated as soon as possible; therefore pressuring the portfolio firms to negotiate rapidlya sale exit, which harm target' negotiation power and increase acquirer' returns.The second, third and fourth objectives of this thesis are pursued by empirical research based on different industry databases. Each of the three presented papers (chapter 3,through chapter 5) are explicitly dedicated to a specific research question.The first chapter 3 started out by arguing that the competitive effect of VC investment is an under-explored question. This idea was coupled with the fact that initial public offering of equity is probably the most important information event in the life of a firm. Therefore the research question is about the competitive effect of venture capital backing in initial public offerings.Two hypotheses underlie this study. First, if initial public offerings announcements reveal of valuable information about issuers, it is likely that investors in competitors of the issued firms use this information to reassess the value of their own firms' future prospects. Therefore, initial public offering announcements are likely to have externality effects for rival firms.Second, if VC investors are considered as having a role in helping their backed firms to deal with the public market, it is likely that competitors react differently to VC backed IPOs. Accordingly, the following two research questions have been formulated: (1) what is competitors' reaction to IPOs announcement? And (2) Is competitors reaction differs on the issued firms' status?In accordance with the literature the results show that in France public market, non VC-backed completed IPOs announcements create a negative reaction toward competitors operating in the same industry. Suggesting that new issued firms will be able to improve their competitive position...

From lab to clinic: the practicality of using event related potentials in the diagnosis of Alzheimer's disease

Suh, Cheongmin 13 July 2017 (has links)
The main objective of this study was to investigate whether event related potentials (ERPs) can be used as a biomarker of disease severity staging in Alzheimer’s disease (AD) within a heterogeneous group of patients presenting to a memory disorders clinic for initial evaluation. Based on the known progression of AD pathology, we hypothesized ERP components would be abnormal, commensurate with disease severity in mild cognitive impairment (MCI) due to AD, mild, and moderate to severe dementia due to AD. ERP components were predicted based on the known sites of their neural generators. ERP peaks measured during an auditory oddball paradigm from twenty-two AD (n=9) and non-AD (n=13) patients were compared to their clinical outcomes using multivariate ANCOVA controlling for age with Bonferroni corrections. The predictive abilities of significant ERP components were examined using a binary logistic regression model. Significant between-group effects were found in N100 distractor amplitude, F(2, 12) = 6.062, p = .015, ηp2 = .503. The results supported our hypothesis that N100 amplitude would be increased in AD, suggesting that sensory gating may be more impaired in mild AD than in non-AD related cognitive impairment.
