Étude de la dynamique cardiaque par analyse d'images tridimensionnelles

Les maladies cardiovasculaires demeurent a ce jour la premiere cause de mortalite dans les pays occidentaux developpes. Le diagnostic d'une pathologie permet de prescrire au patient une therapie adaptee avec un succes d'autant plus grand que la detection est precoce. Nous nous interessons dans cette these a l'etude de la dynamique cardiaque par analyse d'images tridimensionnelles, plus precisement a l'etude du ventricule gauche, la pompe principale du systeme de circulation sanguine. La premiere partie de ces travaux porte sur l'etude de la perfusion myocardique par tomoscintigraphie (SPECT) : dans cette etude, deux images 3D fonctionnelles du ventricule gauche sont acquises afi n de detecter, par comparaison, d'eventuelles ischemies ou infarctus. Un outil a ete developpe pour mettre en correspondance ces images de facon automatique et de normaliser la geometrie de ces images dans un coeur de reference, en vue d'une quanti fication objective en 3D de l'etendue d'une pathologie. Cet outil a ete mis au point sur une base de donnees d'entrainement de 40 cas et evalue sur une base de donnees de routine de 250 cas avec un succes de 97 %. La seconde partie de ces travaux porte sur l'etude du mouvement du ventricule gauche : nous decrivons une classe de transformations planispheriques 4D qui permettent de decrire le mouvement du ventricule en 4D (espace + temps). Ces transformations sont continues, de finies grâce a la donnee d'un nombre reduit de parametres. Elles sont decrites dans une geometrie particulierement adaptee, permettant une ecriture simple de la transformation. De plus, il est possible de realiser une decomposition du mouvement dont la description spatiale et temporelle fournit des parametres quantitatifs en vue d'une analyse objective et, potentiellement, et d'un diagnostic independant de l'operateur. La methode a ete testee sur des sequences d'images tomoscintigraphiques synchronisees a l'electro-cardiogramme (gated SPECT) et par IRM marquees (tagged MRI).
Distributed Usage Control Architecture for Business Coalitions

The dynamic environment of Business Coalition (BC) requires a flexible access control approach to deal with user management and policy writing. However, the traditional approach applied to BC assigns to access control a burden, mainly to the service provider, thus requiring ad hoc schemes to mitigate the lack of controls developed to BC needs. We present a brokered access control architecture, based on UCONABC, to obtain an integrated usage control management for BC. The broker intermediates contract establishment between service provider and consumer, and derives from it the policies to regulate the usage at service-level. The consumer defines user-level policies to control the usage of the contracted services. We developed a web services based prototype to evaluate the feasibility of our proposal. The proposed architecture enables distribution of duties and integration of usage control management in a loosely coupled fashion, providing the flexibility desired in BC environments.
Examination of the AHA!-illness relation in male and female university students from Australia, India, and the United States

The search for the link between negative emotions and later health problems continues to be a dominant theme in behavioral medicine. Although researchers have identified significant relations between illness and anger, most studies focus selectively on one anger domain: either the affective, attitudinal, or behavioral component. In this study, we first related all three components of the AHA! (anger, hostility, and aggressive behavior) syndrome to somatic complaint reports in a male and female young adult population drawn from three countries. In subsequent analyses, we related multidimensional characteristics of anger to illness in those young adults who regularly use tobacco and alcohol. In both the total sample and the substance user analyses, we found that the anger-illness profile varied as a function of gender.
A novel reconfigurable maze antenna for multi-service wireless universal receivers

A novel design of multi-band multi-service reconfigurable antenna has been developed, and is comprised of multi-segment printed loop structure. The developed antenna looks like a maze and can be easily configured by altering its multi-segment interconnectivity using multitude of switches. Modeled and measured results including the effects of the switching elements will be presented here in details.
On the Precoder Design for Block Diagonalized MIMO Broadcast Channels

Block diagonalization (BD) is a linear precoding technique for MIMO broadcast channels such that it completely eliminates the multiuser interference. Consequently, the precoder of a user must lie in the null space of a matrix composing of other users' channel matrices. In this way, the problem of the precoder design is closely related to finding a basis of the null space of the matrix, which can be computed by, e.g., the singular value decomposition (SVD). Recently, a generalized channel inversion (GCI) method was introduced as a low-complexity design for BD. The GCI-based precoder design is also shown to be optimal for BD. However, since the GCI-based design relies on the pseudo-inverse of a matrix, there are many settings, to which this method is not applicable. In this letter, we first provide a connection between the SVD- and GCI-based designs using the results from linear algebra. Then, from this connection, we propose a precoder design that is devised for the cases where the GCI-based method cannot handle.
100 Gbit/s OOK using a silicon-organic hybrid (SOH) modulator

We demonstrate a silicon-organic hybrid (SOH) Mach-Zehnder modulator suitable for 100 Gbit/s on-off keying (OOK) with peak-to-peak drive voltages of 1.4 V and energy consumption below 100 fJ/bit. Devices were fabricated using standard processes on a commercial silicon photonic platform.
Management of invasive candidal infections: results of a prospective, randomized, multicenter study of fluconazole versus amphotericin B and review of the literature.

We conducted a prospective, randomized, multicenter study comparing fluconazole and amphotericin B in the treatment of candidal infections. One hundred and sixty-four patients (60 of whom were neutropenic) with documented or presumed invasive candidiasis were assigned to treatment with either fluconazole (400 mg daily) or amphotericin B (25-50 mg daily; 0.67 mg/kg daily for neutropenic patients). Clinical response and survival rates were assessed at 48 hours, after 5 days, and at the end of therapy. Overall response rates to fluconazole and amphotericin B were similar (66% and 64%, respectively). There were no differences in response as related to site of infection, pathogen, time to defervescence, relapse, or survival rates between the groups. Adverse effects were more frequent with amphotericin B (35%) than with fluconazole (5%; P < .0001). The results of this study confirm that fluconazole is as effective as but better tolerated than amphotericin B in the treatment of candidal infections.
SELF-REPORT OF DEPRESSED MOOD AND DEPRESSION IN WOMEN WITH TYPE 2 DIABETES

The purpose of this cross-sectional analysis (N = 53) was to (a) describe the self-reported prevalence of depressed mood and depression in women with type 2 diabetes; (b) to describe the antidepressive agents and dosages prescribed for depression treatment in women with type 2 diabetes; and (c) to examine differences in diabetes-related health outcomes (physiologic, psychosocial, and health functioning variables) with respect to depressed mood. Forty-four percent of women in this sample reported a depressed mood and 34% of the sample reported a history of depression. The majority of women with a history of depression were taking an antidepressive agent at the time of assessment (94%). Most women were treated with selective serotonin reuptake inhibitors (SSRIs). Women with depressed mood demonstrated poorer psychosocial adjustment and health functioning compared to women without a depressed mood; however, no differences in physiological outcomes were demonstrated. Only 18% of the participants were currently being treated with psychotherapy in conjunction with medication. Further research on this understudied population is indicated.
Role of interleukin-6 in T-cell activation during primary and secondary infection with Listeria monocytogenes

Injection of recombinant interleukin-6 (IL-6) into mice enhances recovery from infection with Listeria monocytogenes. In this study, the role of IL-6 during primary and secondary Listeria infection was further tested. Neutralization of IL-6 by polyclonal antibody exacerbated primary infection and significantly delayed gamma interferon production by cultured spleen cells. In contrast, administration of anti-IL-6 antibody at the time of secondary infection did not affect the recovery of mice from infection or gamma interferon production, showing that activated T cells are not dependent on IL-6.
Acoustic characterization of children with speech delay

Over the past two decades, significant advances have been made in speech analysis and speech pattern recognition techniques, however, the penetration of these advances (notably in pattern recognition techniques) into the speech disorders research arena has lagged, and penetration into the clinic is virtually non-existent. Here we examine one approach to adapting and extending speech recognition technology based on Hidden Markov Modeling (HMM) to an analysis of speech from children with speech disorders of unknown origin. Specifically, we examine the use of normal-speech trained HMMs to identify acoustically defined categories of segmental distortions, and use those categories to characterize differences among a group of children with developmental speech delays.
Eddy Current NDT for Anisotropic Composites

3D FEM shell elements are used to determine the sensor impedance variation due to ferromagnetic anisotropic metal fibre composites (FAMFC). The homogenization of the FAMFC is realized by the inverse method. The impedance variation gives the information about the lift-off and/or the FAMFC integrity
An Analysis of Dynamic Instability on TC-Like Vortex Using the Regularization-Based Eigenmode Linear Superposition Method

In this paper, the eigenmode linear superposition (ELS) method based on the regularization is used to discuss the distributions of all eigenmodes and the role of their instability to the intensity and structure change in TC-like vortex. Results show that the regularization approach can overcome the ill-posed problem occurring in solving mode weight coefficients as the ELS method are applied to analyze the impacts of dynamic instability on the intensity and structure change of TC-like vortex. The Generalized Cross-validation (GCV) method and the L curve method are used to determine the regularization parameters, and the results of the two approaches are compared. It is found that the results based on the GCV method are closer to the given initial condition in the solution of the inverse problem of the vortex system. Then, the instability characteristic of the hollow vortex as the basic state are examined based on the linear barotropic shallow water equations. It is shown that the wavenumber distribution of system instability obtained from the ELS method is well consistent with that of the numerical analysis based on the norm mode. On the other hand, the evolution of the hollow vortex are discussed using the product of each eigenmode and its corresponding weight coefficient. Results show that the intensity and structure change of the system are mainly affected by the dynamic instability in the early stage of disturbance development, and the most unstable mode has a dominant role in the growth rate and the horizontal distribution of intense disturbance in the near-core region. Moreover, the wave structure of the most unstable mode possesses typical characteristics of mixed vortex Rossby-inertio-gravity waves (VRIGWs).
Consistent dynamic equity market code-books from a practical point of view

Gebrauchliche Aktienpreis- bzw.Martingalmodelle beschreiben die Dynamik des Preises einer Aktie unter einem Martingalmas; grundlegendes Beispiel ist das Black-Scholes Modell. Im Gegensatz dazu zielt ein Marktmodell darauf ab die Dynamik eines ganzen Marktes (d.h. Aktienpreis plus abgeleitete Optionen) zu beschreiben. In der vorliegenden Arbeit beschaftigen wir uns mit arbitragefreien Modellen die die Dynamik eines Aktienpreises sowie flussig gehandelter Derivate beschreiben. ("equity market models" respektive "market models for stock options"). Die Motivation derartige Modelle zu betrachten, liegt darin, dass europaische Optionen flussig gehandelt werden und daher Ruckschlusse auf die zugrundeliegende Stochastik erlauben. Marktmodelle werden auch fur Anleihen angewandt; wir verweisen auf Heath, Jarrow, and Morton [1992]. In jungerer Zeit beeinflust dieser Zugang auch Aktienpreismodelle (siehe beispielsweise Derman and Kani [1998], Dupire [1996]). Derman und Kani schlagen vor, die dynamische Entwicklung von Markten mittels Differentialgleichungen fur Aktienpreis und volatility surface zu modellieren. Ein anderer Zugang wird von Schonbucher [1999] gewahlt; hier ist der Ausgangspunkt die gemeinsame Dynamik von Aktienpreis und impliziten Black-Scholes Volatilitaten. Carmona and Nadtochiy [2009] schlagen ein Marktmodell vor, in dem der Aktienpreis als exponentieller Levy-Prozes gegeben ist. In diesem Fall wird eine zeitinhomogene Levy-Dichte verwendet um die zusatzlichen, durch Optionspreise gegebenen Informationen miteinzubeziehen. Der erste Teil dieser Dissertation beschreibt zwei unterschiedliche Zugange um durch den Markt gegebene Informationen zu beschreiben. Einerseits kann dies durch ein local volatility Codebuch geschehen, andererseits kann ein Levy-Dichte Codebuch verwendet werden. Wir beschreiben verschiedene Kalibrierungsverfahren; insbesondere vergleichen wir parametrische mit nicht-parametrischen Methoden. Im zweiten Abschnitt beschreiben wir verschiedene dynamische Modelle, die entstehen, wenn man die beiden obigen Codebucher "in Bewegung setzt". D.h. wir beschreiben dynamische local-volatility sowie dynamische Levy-Dichte Modelle. Besonderes Augenmerk liegt dabei auf der Konsistenz (d.h. Aribtragefreiheit) dieser Modelle. Aufgrund der zusatzlichen stochastischen Dynamik, erscheint dieser Aspekt durchaus als Herausforderung. Im letzten Teil dieser Arbeit betrachten wir einen speziellen Typ von Levy-Modellen. Die spezielle Struktur der Modellparameter ist durch eine Kalibrierung an Marktdaten gemas Ortega et al. [2009] motiviert. Wir berechnen Konsistenzbedingungen fur den vorliegenden speziellen Typ und implementieren sie mithilfe eines geeigneten Euler-Schemas.
Neural Network-Based Approach for Face Recognition Across Varying Pose

At present, frontal or even near frontal face recognition problem is no longer considered as a challenge. Recently, the shift has been to improve the recognition rate for the nonfrontal face. In this work, a neural network paradigm based on the radial basis function approach is proposed to tackle the challenge of recognizing faces in different poses. Exploiting the symmetrical properties of human face, our work takes the advantage of the existence of even half of the face. The strategy is to maximize the linearity relationship based on the local information of the face rather than on the global information. To establish the relationship, our proposed method employs discrete wavelet transform and multi-color uniform local binary pattern (ULBP) in order to obtain features for the local information. The local information will then be represented by a single vector known as the face feature vector. This face feature vector will be used to estimate the frontal face feature vector which will be used for matching with the actual vector. With such an approach, our proposed method relies on a database that contains only single frontal face images. The results shown in this paper demonstrate the robustness of our proposed method even at low-resolution conditions.
In vivo proton MR spectroscopy of pancreatic neuroendocrine tumors in a multiple endocrine neoplasia type 1 conditional knockout mouse model

MR spectroscopy (MRS) can improve diagnosis and follow treatment in cancer. However, no study has yet reported application of in vivo 1H‐MRS in malignant pancreatic lesions. This study quantitatively determined whether in vivo 1H‐MRS on multiple endocrine neoplasia type 1 (Men1) conditional knockout (KO) mice and their wild type (WT) littermates could detect differences in total choline (tCho) levels between tumor and control pancreas.
STRENGTH AND CONDITIONING PRACTICES OF NATIONAL HOCKEY LEAGUE STRENGTH AND CONDITIONING COACHES

This study describes the results of a survey of the practices of National Hockey League strength and conditioning (NHL S&C) coaches. The response rate was 76.6% (23 of 30). This survey examines (a) background information, (b) physical testing, (c) flexibility development, (d) speed development, (e) plyometrics, (f) strength/power development, (g) unique aspects, and (h) comments. Results indicate, in part, that coaches assess an average of 7.2 parameters of fitness, with tests of strength and power being the most common. All coaches used a variety of flexibility-development strategies. Results reveal that 21 of 23 (91.3%) of NHL S&C coaches follow a periodization model (PM). Of the coaches who follow a PM, 21 of 21 (100%) indicated that their athletes used Olympic-style lifts, and 21 of 21 coaches (100%) trained athletes with plyometric exercises. For those who used plyometrics with their athletes, 17 of 21 (80.1%) reported no plyometric-related injuries in the past year. Coaches who report they did not follow a PM also did not use Olympic-style lifts, plyometrics, or speed development strategies, such as assisted, resisted, or interval training, with their athletes. Finally, coaches reported that the squat and their variations, as well at the Olympic-style lifts and its variations, were most frequently used with their athletes. The survey serves as a review, as well as a source of applied information and new ideas.
Egyptian Magic

the contributions of comparative superstition and folk-lore. It is recognized, however, that Egyptian documents do not leave the situation clear. May not the ka, incorporeal, have hovered about a mummy or a statue occupied by the ba, which was likewise a form of the soul and likewise divine? The ka foraged for the dead,' and it is presumably the ka which was expected (as a spirit) to pass through false doors of solid stone in bearing the spirit of offerings from the offering table (before such a door) to the deceased, present in his mummy or his statue in the tomb chamber or the serdab within. The literature on the ka is extensive; but perhaps the end is not yet. T. GEORGE ALLEN UNIVERSITY OF CHICAGO
Temel Dil Becerileri Eğitiminde Kullanılabilecek Aktif Öğrenme Öğretimsel İş/Taktikleri

Rapidly increasing of knowledge makes the reaching to knowledge more important than having of it. For this purpose, in education field it has been started to use strategies, methods and techniques in which the learner is active and provides reaching to the knowledge. One of these methods is active learning which make students more active in learning process. When the significance of basic language arts, on reaching the knowledge, is considered, it has to build a connection between Turkish language teaching and active learning. By means of this connection, it can be contributed to develop language arts of the learners, and be useful to learn the learning. Therefore, in this study it has been matched educational works and tactics of active learning method and the aims/acquisition of basic language arts (reading, listening/watching, speaking, and writing) in 2005 Turkish Language Curriculum. Besides it has been given some examples about how these tactics can be used in Turkish teaching.
Learning bowing gesture with motion diversity by dynamic movement primitives

Motion diversity is an important factor in resembling motion with human-likeness. In this paper, we propose a method by which a robot acquires gesturing skills with motion diversity. We measured the bowing gesture with a 3D capturing camera and used dynamic movement primitives (DMPs) in order to capture the distribution of kernel parameters. The results showed that the height of kernel parameters have a Gaussian distribution and that the trajectory regenerated with the calculated parameters had the desired motion diversity.
Understanding Internet access and use to facilitate patient portal adoption

Understanding the information-seeking preferences and Internet access habits of the target audiences for a patient portal is essential for successful uptake. The resource must deliver culturally and educationally appropriate information via technology that is accessible to the intended users and be designed to meet their needs and preferences. Providers must consider multiple perspectives when launching a portal and make any needed adjustments once the launch is underway. We report results of a study of 270 parents and caregivers of paediatric patients in a major health system during the process of implementing a patient portal. Through a 26-question paper-and-pencil survey, data were collected on participant demographics, Internet access and use, health information–seeking behaviours, health literacy, and potential use of a patient portal. Results indicate a positive attitude towards portal use but also suggest that low health literacy may be a key issue to portal adoption.
Gaining Credibility and Enhancing Economic Growth Through Regional Integration: The Case for EU Membership of Eastern Europe

Trade between Eastern and Western Europe has increased considerably in the last years. Given this market-induced development, why should it be necessary to advance institutional integration? This paper argues that Central and Eastern European countries (CEECs) can potentially enhance the credibility of their governments' policies through institutional integration with the EU. The paper discusses the credibility problems faced by the CEECs and shows how EU membership will enhance the institutional setting and the governments' credibility. Based on regression results between an indicator of institutional change and key macroeconomic variables, an estimate of the potential impact of the CEECs' accession to the EU institutional framework on growth in the CEECs is derived.
