Full textIn human-agent interaction the engagement of the user is an essential aspect to complete the goal of the interaction. In this thesis we study how the user’s engagement could be favoured by the agent’s behaviour. We thereby focus on the agent’s verbal behaviour considering strategies that regard respectively the form, timing, and content of utterances : We present empirical studies that regard (aspects of) the agent’s politeness behaviour, interruption behaviour, and the topics that the agent addresses in the interaction. Based on the outcomes of the latter study we propose an engagement-driven Topic Manager (computational model) that personalises the topics of an interaction in human-agent information-giving chat. The Topic Selection component of the Topic Manager decides what the agent should talk about and when. For this it takes into account the agent’s dynamically updated perception of the user as well as the agent’s own mental state. The Topic Transition component of the Topic Manager, based upon an empirical study, computes how the agent should introduce the topics in the ongoing interaction without loosing the coherence of the interaction. We implemented and evaluated the Topic Manager in a conversational virtual agent that plays the role of a visitor in amuseum

Full textSpace communication payload as well as magnetic confinement fusion devices, among other applications, are affected by multipactor effect. This undesirable phenomenon can appear inside high frequency (HF) components under vacuum and lead to increase the electron density in the vacuum within the system. Multipactor effect can thus disturb the wave signal and trigger local temperature increases or breakdowns. This PhD research aims to improve our understanding and the prediction of the multipactor effect. The multipactor phenomenon is a resonant process which can appear above a certain RF power threshold. To determine this power threshold, experimental tests or/and simulations are commonly used. We have made a study to evaluate the multipactor power threshold sensitivity to the TEEY. Two particular critical parameters have been found: first cross-over energy and the energies between the first cross-over and the maximum energies. In some situations, the HF components are submitted to DC magnetic fields which might affect the electron emission properties and hence the multipactor power threshold. Current multipactor simulation codes don’t take into account the effect of the magnetic field on the TEEY. A new experimental setup specially designed to investigate this effect was developed during this work. Our new experimental setup and the associated TEEY measurement technique were analysed and optimized thanks to measurements and SPIS simulations. We used the setup to study the influence of magnetic field perpendicular to the sample surface on the TEEY of copper. We have demonstrated that the magnetic field affects the copper TEEY, and hence multipactor power threshold

Full textThis thesis deals with the concept of complex network associated with textual information. We are interested in the analysis of these networks with a perspective of application to social networks. Our first contribution consisted in building an analysis model for a dynamic social network using the agent based modeling (ABM) approach, author-topic modeling (ATM), and using the mathematical framework of pretopology to represent the proximity of the subjects. Our modeling is called Textual-ABM. Our proposal has been to use author-topic modeling to estimate user interest based on text content and to use pretopology to model several relationships and to represent a set of neighborhoods that is more elaborate than a simple relationship. Our second contribution concerns the diffusion of information on a "heterogeneous" social network. We propose to extend the independent cascade epidemic diffusion model (IC) and the pretopological cascade diffusion model that we call Textual-Homo-IC and Textual-PCM respectively. For Textual-Homo-IC, the probability of infection is based on homophilia (resemblance of agents) which is obtained from the textual content using the topic modeling. For Textual-PCM, a pseudo-closure function with different strong levels is proposed to realize a more complex set of neighborhoods. In addition, we propose to use supervised learning to predict the diffusion of a topic with a combination of intrinsic or external factors. Our third contribution concerns the prediction of relationships between co-authors with the addition of a new topological feature related to geographical factors and content features using topic modelling. All this work was achieved by the design of specific algorithms and validated by experiments
Li, Ke. "Exploring Topic Evolution in Large Scientific Archives with Pivot Graphs." Electronic Thesis or Diss., Sorbonne université, 2021. http://www.theses.fr/2021SORUS043.
Full textThere is an increasing demand for practical tools to explore the evolution of scientific research published in bibliographic archives such as the Web of Science, arXiv, PubMed or ISTEX. Revealing meaningful evolution patterns from these document archives has many applications and can be extended to synthesize narratives from datasets across multiple domains, including news stories, research papers, legal cases and works of literature. In this thesis, we propose a data model and query language for the visualization and exploration of topic evolution networks. Our model is independent of a particular topic extraction and alignment method and proposes a set of semantic and structural metrics for characterizing and filtering meaningful topic evolution patterns. These metrics are particularly useful for the visualization and the exploration of large topic evolution networks. We also present a prototype implementation of our model on top of Apache Spark and experimental results obtained for four representative document archives

Full textPrematurity compromizes the neurological outcome. Indeed, white matter damage is linked to preterm birth and occurs more frequently in the infectious context. We have sujected pups to intra-peritoneal injections of interleukin-1β (IL-1β) and aimed to explore the effect of systemic cytokines on brain development under 2 aspects: i) The inflammatory reaction secondary to a brain excitotoxic stress. IL-lp sensitizes the brain to a subsequent excitotoxic stress. This result can be explained by a reduction of the anti-inflammatory response and a potentialization of the noxious effect of TNFα. Ii) Myelination and cognitive functions. An alteration of myelination is observed associated with an axonopathy. In contrast, the morphological aspect of myelin sheath is conserved. Furthermore, mice treated with IL-1β exhibit cognitive dysfunctions at P30. Systemic cytokines are implicated in the pathophysiology of white matter damage, modeling the leucoencephalopathy of the preterm

Full textStarting insulin therapy with daily multi-injections in the elderly type 2 diabetic patients is a difficult challenge. The possible loss of autonomy induced by the treatment and the variability of the insulin needs must be taken into account. In the therapeutic protocols, starting insulin therapy is based on the prescription of low dosage adjusted according to blood glucose results. A time of adjustment is therefore necessary to prescribe the optimal dose.For these reasons, this thesis proposes an original methodology for modeling insulin therapy in elderly subjects with type 2 diabetes from certain biological and clinical endogenous variables with two objectives:1. assist physicians at the stage of determination of insulin prescription, 2. individualize insulin treatment depending on the physiological profile of the patient. The methodology based on fuzzy logic, allowed the analysis of a sample of 71 diabetic patients aged over 65 years. Three profiles types of insulin requirements and the discriminating variables underlying this typology have been identified. Methodology based on case based reasoning allows individualizing the treatment to prescribe insulin dosage from the closest (nearest) cases selected in the sample.Our works provide two main contributions:- on insulin therapy in elderly type 2 diabetic patients, - on the original methodology of the digital process of medical data at therapeutic follow-ups

Full textThe production of 2D cartoons that follows a pattern established in the 1920 involves a very large number of different skills. In contrast to this traditional way, the production of 3D films, using the most recent technology and tools, becomes interesting in terms of time and manufacturing costs. In this competitive context, this thesis aims to contribute to development a platform reconstruction, deformation and animation of 3D models faces for 2D cartoons. Our contributions have focused on the development of a methodology to create 3D virtual faces from a 3D model and a set of 2D drawings representing facial features, the development of a procedure for creating key poses, using several methods of non-rigid deformation and design of a 3D animation module compatible with the standard MPEG-4/AFX

Full textIn fluorescent Microscopy, the impulse response also called Point Spread Function (PSF) creates a blur and a deformation of imaged objects. Accurate model PSF allows to correct this phenomenon and also to define a priori on objet size. Indeed, base on the assumption that fluorescent particles are defined as impulse, biological fluorescent spot can be characterized by PSF. In the first part of this work, we focus on the modelization of fluorescent microscopy PSF. In order to obtain an analytical model, we study the light diffraction theory in perfect optical system. We introduce a 3D analytical model of fluorescent line-scanning confocal microscope PSF using the scalar Debye diffraction integral. This microscope can be considered as widefield microscope in the direction of the line illumination and as point-scanning confocal microscope in perpendicular direction, which yields an asymmetrical PSF in the focal plane. Based on our asymmetric model, we propose also a Gaussian approximation of the PSF. Both models are compared to a ground truth. In the second part, we use these models to detect 3D fluorescent particles. We propose a detection method based on local curvature, combined to a statistical representation of image formation in order to estimate the subvoxel localizations of the detected particles. This representation takes into account noise and PSF analytical models. Moreover, we study the effect of inaccurate PSF approximation on sub-resolution spot detections. Finally, we present practical applications of the method to biological problems, performed in collaboration with other teams of Institut Pasteur Korea

Full textIntroduction : In addition to contractility, afterload is one of the main determinants of left ventricular (LV) performance. Thus, analysis of LV function in hypertension not only requires incorporation of hemodynamics parameters such as LV time-varying volume and pressure, but also LV wall strain and stress. The aim of the present study is to evaluate non invasively LV-arterial coupling in hypertension.Method : LV volumes and pressures curves were obtained from real-time 3D echocardiography (RT3DE) and carotid tonometry, respectively. The pressure-volume (P-V) curves thus obtained were fitted with a non linear least squares method. We then computed the slope and the intercept of time varying élastance, and volume intercept V0. LV-aortic coupling is estimated by the ratio of LV and aortic elastance (Ees and Ea). Energy transfer from the left ventricle to aorta is defined as the ratio of external work and myocardial strain work (Pmeca). Cyclic variations of wall thickness and strain rate were measured by 2D speckle-tracking. Pmeca was calculated according to the produce of LV wall stress with strain rate.Result : A good univariate relationship and a good agreement were found between previous invasive calculation of Ees and our new proposed “Ejection P-V Curve” method. In hypertensive patients, increase in Ea and LV efficiency were compensated by a parallel increase in Ees without change in Ea/EesConclusion : Ees and V0 can be estimated non invasively from modeling of the P-V curve during ejection. This approach was found to be reproducible and sensitive enough to detect an expected difference in LV contractility in hypertensive patients. Due to its non invasive nature, our new proposed “Ejection P-V Curve” method is now applicable to a randomized study of the effect of sodium intake on LV performance in hypertension. Among strengths of these new methods based on RT3DE, is to exclude the necessity of geometrics assumptions for the evaluation of LV volumes. However, 3D analysis of LV strain is not yet fully-developed, with the necessity to improve the performance of frame acquisition and modeling

Full textInflammatory reaction is a benefic process because of its self defense property. However it can induce serious complications qualified as inflammatory pathologies in asthma, allergy and psoriasis. Many anti-inflammatory drugs are known, but they all present side effects which limit their therapeutic use. Human secretory non-pancreatic PLA2s act in hydrolysing membrane phospholipids on the sn-2 position releasing arachidonic acid and lyso-PAF, the precursor of eicosanoids and PAF, lipid mediators on inflammation. In a previous study we described a series of compounds, in the first part, active but not selective, then, in the second part active, selective but possessing a high lipophilicity. We have shown by in vitro fluorimetric assay that some new inhibitors induce a specific inhibition of PLA2-II (CI50= 0,029 µM) without cytotoxicity. LPS 10 µg/mL induced radical oxygen species (O2°- and H2O2) which could be inhibited by the majority of our products. By using microplate cold light cytofluorimetry, we have shown that free radical production was lower in inhibitors-treated cells then that of the control cells. Molecular modelling studies gave more informations about structure-activity relationships and led us made it possible to propose assumptions as for the mechanism of action of these inhibitors on the level of the active site of the enzyme

Full textHigh power consumption is a key factor hindering System-on-Chip (SoC) performance. Accurate and efficient power models have to be introduced early in the design flow when most of the optimization potential is possible. However, early accuracy cannot be ensured because of the lack of precise knowledge of the final circuit structure. Current SoC design paradigm relies on IP (Intellectual Property) core reuse since low-level information about circuit components and structure is available. Thus, power estimation accuracy at the system level can be improved by using this information and developing an estimation methodology that fits IP cores power modeling needs.The main contribution of this thesis is the development of a Hybrid Power Estimation Technique (HPET), in which, information coming from different abstraction levels is used to assess the power consumption in a fast and accurate manner. HPET is based on an effective characterization methodology of the technology library and an efficient hybrid power modeling approach. Experimental results, derived using HPET, have been validated on different benchmark circuits synthesized using the 28nm “Fully Depleted Silicon On Insulator” (FDSOI) technology. Experimental results show that in average we can achieve up to 70X speedup while having transistor-level accuracy. For both analyzed power types (instantaneous and average), HPET results are well correlated with respect to the ones computed in SPECTRE and Primetime-PX. This demonstrates that HPET is an effective technique to enhance power macro-modeling creation at high abstraction levels

Full textThis thesis considers design evaluation and optimisation in the context of nonlinear mixed effect models for multiple responses, as for instance for the joint modelling of the pharmacokinetics and the pharmacodynamics of a drug or for thé pharmacokinetics of a parent drug and its metabolite. We extended the computation of the Fisher information matrix for nonlinear mixed effect models with multiple responses using the usual first-order linéarisation. We evaluated this extension and showed by simulation its relevance. We also extended the Fedorov-Wynn algorithm to include cost functions on the sampling times. We implemented these developments in new versions of the R function PFIM dedicated to design evaluation and optimisation. We also applied them to plasma and intracellular pharmacokinetics of antiretroviral drugs. We performed a review on clinical studies measuring intracellular concentrations of antiretro viral drugs in HIV patients and found that most of these studies had small sample sizes and were not always adequately designed. We developed the first joint pharmacokinetic models of zidovudine and lamivudine and of their respective intracellular metabolites. We estimated the long half-lifes of both metabolites and found large between patients variabilities. Last, we showed that population design optimisation allows the derivation of efficient designs according to clinical constraints for further analysis of these molecules using these joint models

Full textWriting and then a fortiori reading is a too recent invention for evolution to develop a specialized neuronal substrate sustaining the visual word form recognition. Thereby functional region underlying reading process rest on cortical area dedicate to language and visual recognition of objects. However, complete identification of a word requires beyond the orthographic decryption, phonological decoding and semantic recovery. Numerous neuroimaging studies and in particular with fMRI have tried to localize the functional regions sustaining these different cognitive processes. Nonetheless, the weak temporal resolution of fMRI do not allowed revealing the dynamic of integration within the reading network. Electrophysiological recording as EEG permit to show the neuronal dynamic thanks to its excellent temporal resolution. However, localization of the cortical area having generate the scalp electrical field is a complex methodological issue. Since a decade, numerous breakthroughs in methodology allow not only to localize functional region but also the temporal dynamic of their interaction. Moreover, from a localisationnist point of view, current research have adopted an hodotopic vision supposing that the function of a region is more depend of its connectivity with the other region of the network than of its precise location. New methodologies as dynamic causal modeling permit to show the network structure and its dynamic integration. The goal of this thesis has been to use latest methodological development to reveal not only the network of the word recognition, but also to propose a functional model of the integration of the visual stimuli within this network. In particular, we have shown the importance of feedback connection on bottom up processing in word recognition as it has been shown for objects recognition. In addition, we have applied those methodologies to epileptic patients to reveal the influence of a left temporal lesion on the functional reorganization of the reading network

Full textOur aim was to evaluate the interest of two pharmacological approaches (Population Pharmacokinetics/Pharmacodynamics and Pharmacogenetics) to improve the use of drugs in patients presenting with impaired renal functions. In a first part, we determined the influence of renal function on the pharmacokinetics of an anticoagulant (enoxaparin) owing to a population PK modelling approach. This model allowed us to develop a dosing strategy for this drug in renally impaired patients. In an other part, we found that, independently of alteration in the glomerular filtration process, an ABCC2 mutation altering MRP2-mediated methotrexate transport in vitro results in vivo in impaired tubular renal excretion of methotrexate and subsequent renal toxicity. This is the first evidence that genetic factors may contribute to renal drug elimination
