Full textThe increasing complexity of the real-time data acquisition and processing systems (TDAQ : the so-called Trigger and Data AcQuisition systems) in high energy physics calls for an appropriate evolution of development tools. This work is about the interplay between in principle specifications of TDAQ systems and their actual design and realization on a concrete hardware and software platform. The basis of our work is to define a methodology for the development of TDAQ systems that meets the specific demands for the development of such systems. The result is the detailed specification of a "methodological framewor" based on the Unified Modeling Language (UML) and designed to manage a development process. The use of this UML-based methodological framework progressively leads to the setting up of a "home-made" framework, i. E. A development tool that comprises reusable components and generic architectural elements adapted to TDAQ systems. The main parts of this dissertation are sections II to IV. Section II is devoted to the characterization and evolution of TDAQ systems. In section III, we review the main technologies that are relevant to our problematic, namely software reuse techniques such as design patterns and frameworks, especially concerning the real-time and embedded systems domain. Our original conceptual contribution is presented in section IV, where we give a detailed, formalized and example- driven specification of our development model. Our final conclusions are presented in section V, where we present the MORDICUS project devoted to a concrete realization of our UML methodological framework, and the deep affinities between our work and the emerging "Model Driven Architecture" (MDA) paradigm developed by the Object Management Group

Full textThis thesis describes results from fundamental studies of liposomes intended for drug delivery and pH or temperature triggered release. In addition, the effect of lipid composition on bilayer disc formation and a potential application of the bilayer discs were investigated.
The lower pH encountered by endocytosed liposomes can be utilized to trigger drug release. The mechanisms behind cytosolic drug delivery were investigated using two different kinds of pH-sensitive liposomes. The results indicate that incorporation of non-lamellar forming lipids into the endosome membrane may allow for drug escape into the cytosol.
Temperature-sensitive liposomes containing lysolipid (LTSL) release their content almost instantly when heated to temperatures close to the gel to liquid crystalline phase transition temperature (TC). Morphological changes of the liposomes in response to temperature cycling were studied. Temperature cycling induced liposome openings and disintegration of the liposomes into bilayer discs. Incubation of LTSL in the presence of multilamellar liposomes (MLVs) resulted in relocalisation of lysolipid into the MLVs, which affected the rapid release from LTSL. We propose that the presence of micelle-forming components, such as lysolipids and PEG-lipids, facilitates the formation of defects and membrane openings during the initial phase of membrane melting, resulting in the observed rapid release. Similar to added lysolipids, also hydrolysis generated lysolipids induce disc-formation upon heating through TC of the lipid mixture.
Two fundamentally different micelles may form in PEG-lipid/lipid mixtures. We found that discoidal structures are preferred over cylindrical micelles when the mixture contains components that reduce the spontaneous curvature, increase the monolayer bending modulus, or reduce PEG-lipid/lipid miscibility. The large discoidal micelles found at low PEG-lipid content are better described as bilayer discs. We evaluated such discs as model membranes in drug partitioning studies, and suggest that they, in some cases, produce more accurate data than liposomes.

Full textPhysico-chemical characterisation of structure and stability of liposomes intended for drug delivery is the central issue in this thesis. In addition, targeted liposomes to be used in boron neutron capture therapy (BNCT) were developed.
Lysolipids and fatty acids are products formed upon hydrolysis of PC-lipids. The aggregate structure formed upon mixing lysolipids, fatty acids and EPC were characterised by means of cryo-TEM. A relatively monodisperse population of unilamellar liposomes was detected in mixtures containing equimolar concentration of the three components.
The interactions between alternative steric stabilisers (PEO-PPO-PEO copolymers) and conventional PC-and pH-sensitive PE-liposomes were investigated. Whereas the PE-liposomes could be stabilised by the PEO-PPO-PEO copolymers, the PC-liposomes showed an enhanced permeability concomitant with the PEO-PPO-PEO adsorption.
Permeability effects induced by different PEG-stabilisers on EPC liposomes were shown to be dependent on the length of the PEG chain but also on the linkage used to connect the PEG polymer with the hydrophobic membrane anchor.
An efficient drug delivery requires, in most cases, an accumulation of the drug in the cell cytoplasm. The mechanism behind cytosolic drug delivery from pH-sensitive liposomes was investigated. The results suggest that a destabilisation of the endosome membrane, due to an incorporation of non-lamellar forming lipids, may allow the drug to be released.
Furthermore, sterically stabilised liposomes intended for targeted BNCT have been characterised and optimised concerning loading and retention of boronated drugs.

Full textSur l'expérience LHCb une unité de décision en effectue une première sélection. Nous proposons une solution pour sa réalisation. Il s'agit d'une électronique numérique pipelines à 40 MHz et réalisée en composants programmables avec des interfaces LVDS. Une première version du banc de test est présentée afin de générer des stimuli à la cadence de 40 MHz pour des mots jusqu'à 512 bits.
Le preshower fait partie du système calorimétrique de LHCb. Il est composé de 6000 voies de mesure. Le signal physique est d'abord mis en forme grâce à des intégrations analogiques sur 25ns sans temps mort (ASIC). Au bout de 20m de câble, les valeurs d'intégrales (en tension) sont numérisées puis traitées sur une centaine de cartes frontales.
La réalisation de prototypes de la partie de traitement des données ont permis de mettre en concurrence une technologie programmable et une technologie ASIC (AMS 0,35 µm) et de prendre en compte les contraintes fortes en terme de nombre de voies de mesure par carte (128 demi-voies) et de résistance aux radiations.

Full textThe role of the emergency nurse is to provide immediate care to patients or to perform a nursing intervention that can prevent an emergency. They should lead, initiate and coordinate patient care. Factors that affect patient safety could be leadership, working in teams, evidence-based work, communication, training, or patient-centered work. Rapid response system (RRS) was developed to improve patient safety in emergency care. There are four units that are essential for the system to function. The afferent component includes the nurse who is responsible to identify warning signs if the patient is deteriorating and activate RRS. A track-and trigger system based on the patient’s vital signs is used to assist the nurse to identify deteriorating patients on wards. The most common vital signs in emergency care are: respiration, temperature, blood pressure, heart rate, consciousness and urine production. The efferent component is the relief effort that the afferent component calls for by activating RRS when abnormal vital signs are observed and generate a high score in the track-and trigger system. Alternatively, on the advice of the nurse's instinctive feeling that the patient's condition has deteriorated. The aim of this study was to highlight nurses' experiences of applying rapid response system in their work and illustrate its impact on patient safety. The method used was a literature review. Database searches were made in PubMed, CINAHL and Web of Science, which resulted in 16 articles being included in the study. Inclusion criteria used were English language, ’peer-reviewed’ and published in scientific journals between the years 2006-2016. An integrated analysis was used to find similarities and differences in the results. The result showed that RRS increased identification of critically ill patients, resulting in reduced number of cardiac arrests and unexpected deaths and led to more patients being moved to a higher level of care. Difficulties or limitations that emerged were inadequate skills, high workload and hierarchy. Abnormal vital signs were taken more seriously compared to "silent" changes. The nurses sometimes activated the system due to concerns based on their clinical experience, despite vital signs being normal. RRS was a help to manage critically ill patients and served as the hospital's Department 112. The emergency medical team mostly supported the nurses, but sometimes they experienced negative attitudes, which affected the future activations negatively. The conclusion of this literature review indicates that RRS for patient safety could help nurses in their daily work by promoting safe care. The nurse's experiences highlight the favorable circumstances and perceived difficulties with the RRS, which could be used for further research to develop the system.

Full textLe travail présenté dans ce document concerne la recherche d'un signal supersymétrique caractérisé par la production de deux stops se désintégrant en deux jets de b, un électron, un muon et de l'énergie manquante. Cette étude a été menée auprès de l'expérience DØ, située sur l'anneau du Tevatron à FermiLab (Chicago, USA) et dont l'énergie dans le centre de masse atteint 1,96 TeV. L'analyse de ce signal porte sur les données collectées pendant la phase IIa du détecteur DØ, d'avril 2003 à mars 2006 (~1fb^-1). L'étude d'un tel signal requiert une bonne maîtrise des différents sous-détecteurs ; aussi bien du calorimètre (électron, jet et énergie transverse manquante) que des détecteurs de muon et des trajectographes.
Le Tevatron est un collisionneur hadronique et le nombre de processus du Modèle Standard présentant la même signature que le signal recherché est faible. Le bruit de fond de cette analyse est donc dominé par les processus QCD. Après l'application de critères de sélection permettant de diminuer principalement cette contribution, aucun excès significatif des données par rapport aux prévisions du Modèles Standard n'a été observé. La sensibilité de l'expérience DØ a été améliorée et le domaine d'exclusion dans le plan [m˜_nu,m˜_t1 ] étendu jusqu'à des masses de stop de 170 GeV/c2 et de sneutrino de 105 GeV/c2.
De plus, une partie de mon travail préparatoire a consisté dans l'élaboration d'un outil de discrimination des objets calorimétriques au niveau 3 de déclenchement ; ainsi que la calibration des deux chaînes de lecture simulées au niveau 1.

Full textI performed my thesis work in Particle Physics at the Laboratoire Leprince-Ringuet of the Ecole Polytechnique. I have participated to the analysis of the 8 TeV proton-proton collisions produced by the Large Hadron Collider (LHC) and collected by the CMS experiment. The discovery of the Higgs boson has been a major breakthrough in particle physics as the mass of the vector bosons are explained through their interactions with the Higgs field. I worked on the newly discovered Higgs boson analysis. As its direct coupling to fermions remained to be exhibited, I focused on the search for the Higgs boson decaying in tau lepton pairs. The Higgs decay into a tau pair is the only channel allowing the couplings between the Higgs boson and the leptons to be measured. This is due to the large event rate expected in the Standard Model compared to the other leptonic decay modes. The Higgs boson decaying to tau lepton analysis is particularly challenging at the trigger level because the large background imposes high thresholds. I worked on a trigger that ran at the end of the data-taking using the missing transverse energy to lower the threshold on the single lepton. This approach allows the recovery of 41% of the signal events. Events with missing transverse momentum were selected in order to control the trigger rate. My personal contribution consisted in a thorough characterization of this trigger, including the measure of the associated uncertainty. The results of this approach led to an amelioration of 2% in the exclusion limits computed in the Higgs to taus semileptonic channel. For the Run 2, the center-of-mass energy of the LHC collisions has been increased to 13 TeV and the instantaneous luminosity will reach 2E34/cm2/s. To guarantee a successful and ambitious physics program under this intense environment, the CMS Trigger and Data acquisition system has been consolidated. In particular the Level 1 (L1, hardware based first level of the CMS trigger system) benefited from the recent microTCA technology allowing the calorimeter granularity to be better exploited with more advanced algorithms. Thanks to the enhanced granularity provided by the new system, an innovative dynamic clustering technique has been developed to obtain an optimized tau selection algorithm. I took the responsibility of developing a complete new tau trigger algorithm at L1 and measuring its performance. This original approach resulted in the first hardware tau lepton trigger efficient at a hadron collider with a sustainable rate. I had the opportunity to present a poster showing my work at the ICHEP-2014 conference, in Valencia and the proceedings were published in Nuclear Physics B afterwards. During my last year of PhD I focused on the Higgs decays into di-taus analysis, initiating the very first matrix element (ME) approach in this channel, starting with the most sensitive final state: the semileptonic decay mode. The aim is to increase the sensitivity of the analysis to the SM Higgs boson, with respect to the traditional methods. No ME-based analysis using tau leptons has ever been published. The novelty of my work is the treatment of the tau decay. In addition, I have derived a parameterization of the detector response through transfer functions. Finally, the numerical aspects related of multidimensional integrals computations have been tackled. I have fully characterized the method using simulated samples before applying it to the 8 TeV data. The performance in the context of the CMS Higgs into di-taus of this pioneering method are very promising, with a S/B ratio improved by a factor 3, and constitute a baseline for the analysis of the upcoming Run 2 data of the LHC
