Résumé :
Purpose The purpose of this paper is to expand project management theory about practice and theory for practice through a new conceptual model developed from the transformational production management, strategic management and complexity bodies of theory. Design/methodology/approach This research uses a grounded theory methodology. A preliminary model is developed and tested against two case studies. The model is revised and tested using a purposively selected focus group before being presented in this paper. Findings The research indicates that the “final state convergence model” which has been synthesized from the transformational production management, strategic management and complexity theories. The model illuminates the complexities that can exist within the practice of project management. Research limitations/implications The final state convergence model provides a novel approach to synthesizing new bodies of theory into traditional project management theory. Practical implications The model challenges practitioners to think beyond their current conceptual base of traditional project management methodologies, systems, and processes toward a broader conceptualization of project management. Originality/value The research adds to the theory about practice and theory for practice through the development of a new model which not only illuminates the complexities of project management but enriches and extends the understanding of the actual reality of projects and project management practices.

Résumé :
In this talk we discuss the effects of the hadronic rescattering on final state observables in high energy nuclear collisions. We do so by employing the UrQMD transport model for a realistic description of the hadronic decoupling process. The rescattering of hadrons modifies every hadronic bulk observable. For example apparent multiplicity of resonances is suppressed as compared to a chemical equilibrium freeze-out model. Stable and unstable particles change their momentum distribution by more than 30% through rescattering. The hadronic rescattering also leads to a substantial decorrelation of the conserved charge distributions. These findings show that it is all but trivial to conclude from the final state observables on the properties of the system at an earlier time where it may have been in or close to local equilibrium.

Résumé :
A stochastic model is presented for staging transitions in graphite intercalation compounds. Three types of kinetic processes are introduced into the domain model of Daumas and Herold, and a one-dimensional Monte Carlo simulation is carried out within the framework of a single-column model to study the time evolution of the system for a variety of cases of staging transitions. Results of Monte Carlo simulations from stage 3 to stage 2 after a sudden change of chemical potential show that the staging transition depends sensitively on the final value of the chemical potential μf, temperature of the system, and the kinetic coefficients. When μf is taken in a certain range in the phase diagram, the time evolution of the structure factor demonstrates the coexistence and no significant broadening of peaks corresponding to the initial and final stage states. For other values of μf, it is observed that the staging transitions proceed via disordered states and in some cases the final states are also disordered. Similar results are obtained for staging transitions from stage 4 to stage 3. Simulations are also made for staging transitions in which the start is from stage 4 and suddenly μ changes to a value in the stage-2 stable region. It is found that the system transforms either directly into a stage-2 state or into a metastable stage-3 state without showing evidence of further transition into a final stage-2 state, depending upon the values of μf, and kinetic coefficients. A discussion is presented on the possibility of observing an intermediate metastable stage-3 state during the transition from stage 4 to stage 2.

Résumé :
We propose a mechanism of opinion evolution in a closed system. The opinion evolution process can be described as the disposal of multi-information inputs with one opinion accepted as the output. We introduce the opinion neutrality in the system, observing the characteristics of the opinion evolution process; and find that the initial opinion distribution fractions play an important role in the final results. When the two opposite opinions' fraction are equal, the neutrality fraction will affect the final opinion distribution dramatically.

Résumé :
The analysis is presented for the first moments of collective observable distributions in two-jet events for various interaction types and for wide initial energy range. These observables include sphericity, thrust, components of transverse particle momentum, alignment and planarity. Database of experimental results created in the framework of the paper includes data for all interactions. Energy dependencies of average values for collective observables except components of transverse momentum show universal behavior for various interactions. Particle transverse momentum as well as its components increase faster for e+e- interaction with growth of [Formula: see text], than that for other interactions. Empirical analytical functions are suggested for description of energy dependence for all collective observables under study with exception of infrared-stable thrust variable. Energy dependence for average thrust is compared with QCD predictions including perturbative part and analytical phenomenological corrections which account for nonperturbative effects. Dispersive model and single dressed gluon approximation are considered for description of energy dependence of first moment of thrust distribution and estimation of strong coupling constant for various interactions as well as for joint sample. The dispersive model allow to describe average thrust versus initial energy in wide range of [Formula: see text] down to strongly nonperturbative domain [Formula: see text] at qualitative level at least. Study of event shape observables allows to obtain estimations of αS(MZ) which are in reasonable agreement both with world average value and with results extracted in the framework of other methods. Using suggested analytical fitted functions some estimations of values of collective parameters under study have been obtained for present and future facilities. In TeV energy domain average values of collective observables either depend on [Formula: see text] weakly or do not depend on initial energy at all within errors. Thus, the TeV scale can be considered as an estimation of the low boundary of asymptotic region for traditional collective parameters. Usually, multiplicity dependence of collective observables under consideration agree with power function in energy domain [Formula: see text] at qualitative level at least. Behavior of sphericity versus multiplicity and comparison of experimental results with model calculations allow to suggest that the universal estimation of the low energy boundary for experimental appearance of event jet structure in multiparticle production processes is [Formula: see text].

The latest advances in Standard Model measurements performed by the ATLAS experiment at the LHC are discussed. Vector-boson scattering processes have been observed in several final states (ZZ, WZ, same-sign WW), and evidence has been reached in the Zγ final state. The experimental precision of QCD measurements has reached the same order as the theoretical uncertainties on the NNLO calculations. Evidence for the triboson WVV final state has been achieved. The latest results on V+jets, Zγ, W+W− and direct photons production are presented. New results on jet substructure and forward proton tagging program are also discussed.

A search for quantum black holes with color charge decaying to one electron and one quark has been performed using data collected by the ATLAS Experiment at the Large Hadron Collider corresponding to 2.29 fb−1. No excess over the expected Standard Model interactions has been observed. Limits are set on the production cross section for events with one electron and one jet resulting from new physical phenomena. Models with a combined invariant mass of the electron and jet larger than or equal to 2.5TeV and a cross section above 2.6 fb are excluded at the 95% confidence level. This allows the exclusion of a significant part of the parameter space of quantum black hole models.

Résumé :
Nel modello standard (SM), le masse dei fermioni sono generate attraverso gli accoppiamenti di Yukawa tra i campi di Higgs e fermionico. La misura di questi accoppiamenti e' fondamentale per corroborare la natura del bosone con massa intorno a 125 GeV scoperto dalle Collaborazioni ATLAS e CMS nel 2012. Il canale tautau e' particolarmente promettente, grazie al branching ratio relativamente alto e alla contenuta contaminazione da parte dei processi di fondo. In questa tesi vengono riportati i risultati della ricerca di un bosone di Higgs SM nello stato finale comprendente due leptoni tau. Sono stati analizzati gli interi dataset di collisioni p-p raccolti da CMS nel 2011 e nel 2012, corrispondenti alla luminosita' di 4.9 fb-1 a sqrt(s)=7 TeV e 19.7 fb-1 a sqrt(s)=8 TeV. Sono stati studiati tutti i sei possibili stati finali di-tau: mutau, etau, tautau, emu, mumu e ee. Questa tesi, in particolare, descrive l'analisi condotta nello stato finale doppio adronico tautau. Nei dati e' stato osservato un eccesso di eventi rispetto alla predizione per i soli fondi. La significanza locale eccede le 3 deviazioni standard per valori di mH compresi tra 115 e 130 GeV. Il prodotto della sezione d'urto per branching ratio, misurato per il segnale a mH=125 GeV, corrisponde a 0.78+/-0.27 volte il valore predetto dallo SM. Questo costituisce l'evidenza dei decadimenti in coppie di leptoni tau del bosone di Higgs a 125 GeV. Nello SM, la massa del bosone di Higgs non è protetta da divergenze date dalle correzioni a loop e la cancellazione di queste divergenze avviene tramite il cosiddetto fine tuning. In modelli oltre lo SM, ad esempio il Minimal Supersymmetric Standard Model (MSSM), la cancellazione avviene in maniera naturale grazie all'introduzione di un bosone (fermione) per ogni fermione (bosone) presente nello SM. In questa tesi viene anche descritta la ricerca di un bosone di Higgs neutro MSSM nel canale tautau. Questo canale e' particolarmente interessante poiche' i decadimenti in tau sono favoriti in buona parte dello spazio dei parametri. Non viene osservato nessun eccesso e si procede quindi a fissare limiti di esclusione nello spazio dei parametri di diversi benchmark scenarios. Vengono inoltre forniti limiti sul prodotto di sezione d'urto per branching ratio per i due piu' rilevanti modi di produzione, gluon-gluon fusion e produzione associata con b-quark.

Résumé :
Collision avoidance systems have become an integrated part of modern vehicles and aim to avoid accidents or mitigate the crash severity for the occupant. For example, the autonomous emergency braking system influences the pre-crash state of the occupant in sitting posture, stress state, or velocity. The occupant might try to retain its posture by activating muscles, which induce muscle bracing and could counteract the movement of the occupant in the pre-crash phase.  Therefore, it is essential to study the influence of active musculature on occupant response in pre-crash and crash events. A finite element human body model (HBM) with and without closed-loop muscle activation control was used to simulate the occupant response during those events. Comparing the HBM responses & head kinematics reveal an influence of muscle bracing in the evasive braking manoeuvre. Simulating the pre-crash and in-crash phase in two stages can provide multiple benefits. However, the correlation between a single-stage simulation (baseline) and a two-stage simulation needs to be investigated. The baseline simulation uses an active HBM to model an occupant during an evasive braking manoeuvre and the muscles are deactivated when entering the frontal impact phase. The parameters of the final pre-crash state, which are needed to mimic the baseline’s response when transitioning from the pre-crash to the in-crash event are investigated in this study. For that reason, sitting position, stress state and velocity are transferred respectively to the initial passive in-crash HBM state. The simulations enabled the comparison of occupant response and calculation of cross-correlation. Each retainment strategy gave a good cross-correlation with the baseline simulation.
Kollisionsundvikande system har blivit en viktig del i moderna fordon där syftet är att undvika olyckor samt att minska allvarhetsgraden av olyckor för de åkande. Ett exempel är nödbromssystem som kan påverka den åkandes initiala tillstånd direkt före en krock som, till exempel, sittposition, spänningstillstånd, eller initial hastighet inför krock. Den åkande kan försöka att bibehålla sin hållning genom att aktivera sina muskler vilket påverkar rörelsen av dess kropp under för-krocks fasen. Det är därför viktigt att studera hur aktiva muskler påverkar rörelsen av kroppen hos den åkande under både före krocksfasen och själva krockfasen. En finit element humanmodell (HBM) med och utan reglerad muskelaktivitet används för att prediktera responsen hos den åkande i båda faserna. En jämförelse mellan simuleringarna visar att aktiva muskler kan påverka åkandekinematiken under bromsningsförloppet. Att simulera fasen före krock och fasen under krock i två steg kan medföra flera fördelar. Korrelationen mellan en enkelstegssimulering (originalsimulering) och en tvåstegssimulering måste dock studeras. Som originalsimulering används en aktiv HBM för att modellera den åkande under för-krocksfasen där den reglerade muskelaktiviteten inaktiveras under krockfasen. I denna studie undersöks den åkandes initiala tillstånd före krocken som behövs för att efterlikna originalsimulerings respons vid övergången från för-krocksfasen till krockfasen. Av den anledningen mappas det passiva HBM-tillståndet till det slutliga tillståndet av före krocksfasen för sittposition, spänningstillstånd respektive hastighet. Simuleringarna möjliggjorde en jämförelse av åkande respons och beräkning av korskorrelation. Varje mappningsstrategi gav en bra korskorrelation med originalsimuleringen.

Résumé :
A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is presented. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of sqrt{s}=8 TeV at the Large Hadron Collider recorded by the ATLAS detector. The data were collected in 2012, correspond to an integrated luminosity of 20.3 fb-1 and represent the full 8 TeV dataset. This search is performed in the tau-tau final state, with one tau lepton decaying leptonically and the other hadronically. The analysis is optimized in three categories, addressing low-mass Higgs bosons which are accompanied by a bottom quark induced jet or not and high-mass Higgs bosons. No deviations from Standard Model predictions are observed, and therefore no evidences of new Higgs bosons are found. Exclusion limits are set on the cross-section times branching fraction of the Higgs bosons and for parameters m_A and tan{beta} of MSSM benchmark scenarios
In dieser Arbeit wird die Suche nach neutralen Higgs-Bosonen im Rahmen des Minimalen Supersymmetrischen Standardmodells (MSSM) vorgestellt. Die Analyse basiert auf dem kompletten Datensatz von Proton-Proton-Kollisionen des Large Hadron Colliders, LHC, die mit dem ATLAS-Detektor bei einer Schwerpunktsenergie von sqrt{s}=8 TeV im Jahr 2012 aufgenommen wurden. Die Daten entsprechen einer Luminosität 20.3 fb-1. Die Suche fokussiert auf den Tau-Tau Endzustand, wobei ein Tau-Lepton hadronisch zerfällt und das andere leptonisch, entweder in ein Elektron oder in ein Muon. Die Analyse wurde in drei Kategorien optimiert, um sowohl für Higgs-Bosonen im niedrigen Massenbereich von 90-200 GeV als auch im hohen Massenbereich von 200 GeV bis 1 TeV sensitiv zu sein. Der niedrige Massenbereich wurde dabei in zwei Unterkategorien geteilt, entsprechend der Anwesenheit bzw. Abwesenheit von zusätzlichen, durch b-Quarks induzierten Jets, um die Empfindlichkeit für spezielle Higgs-Boson-Produktionsmodi zu erhöhen. Im Rahmen dieser Analyse wurden keine Hinweise auf neue Higgs-Bosonen gefunden und daher Ausschlussgrenzen auf den Wirkungsquerschnitt x Verzweigungsverhältnis gesetzt. Ebenfalls wurden die Resultate in MSSM-Benchmark-Szenarien interpretiert

Résumé :
This thesis presents a search for Supersymmetry in events with at least two hadronically decaying tau leptons and missing transverse energy. The ana\-lysis is focused on the electro-weak production of gaugino pairs. Electroweak production processes for SUSY particles are promising candidates for the discovery of Supersymmetry with $R$-parity conservation at hadron-hadron colliders. For the analysis a sample of proton-proton collisions at a center of mass energy of $\sqrt{s}=\unit[8]{TeV}$ with an integrated luminosity of $\int {\cal L}~\mathrm{dt}= \unit[20.3]{fb^{-1}}$ is used. The collisions have been recorded with the ATLAS detector at the LHC in the year 2012. In two different selections the Standard Model predictions are compared with the observations. The observation of 6 events in the first selection and 14 in the second does not deviate significantly from the Standard Model with an expectation of 11 events in the first selection and 17 in the second. These results are interpreted in a phenomenological Minimal Supersymmetric Standard Model and in simplified models. For a simplified model with a chargino-neutralino pair production scenario the parameter space for masses of the lightest neutralino up to $\unit[100]{GeV}$ and up to $\unit[350]{GeV}$ for the lightest chargino mass can be excluded. For a simplified model with chargino pair production processes the parameter space for the lightest neutralino mass up to $30-\unit[50]{GeV}$ in a range for the lightest chargino mass of $170-\unit[330]{GeV}$ can be excluded. This thesis is focused on the estimation techniques of Standard Model background processes. Different methods for the estimation of the background originating from $Z$-boson and top-quark decays are investigated.
In dieser Arbeit wird eine Suche nach Supersymmetrie für Ereignisse mit zwei hadronisch zerfallenden Tau Leptonen und fehlender Transversalenergie im Endzustand präsentiert. Die Analyse konzentriert sich dabei auf die elektroschwache Produktion von Gaugino Paaren. Elektroschwache Produktions\-prozesse sind vielversprechende Kandidaten für die Entdeckung der Supersymmetrie mit $R$-Paritätserhaltung an Hadron-Hadron Teilchenbeschleuni\-gern. Für die Analyse wurde ein Datensatz von Proton-Proton Kollisionen bei einer Schwerpunktenergie von $\sqrt{s}=\unit[8]{TeV}$ mit einer integrierten Luminosität von $\int {\cal L}~\mathrm{dt}= \unit[20.3]{fb^{-1}}$ verwendet. Die Daten wurden mit dem ATLAS Detektor am LHC im Jahr 2012 aufgezeichnet. Die beobachteten Datenereignisse wurden mit den Vorhersagen des Standardmodells für zwei unterschiedliche Sätze von Signalauswahlkriterien verglichen. Die Beobachtung von 6 Ereignissen in der ersten Signalregion und 14 Ereignissen in der zweiten weicht nicht signifikant von den Vorhersagen des Standardmodells mit 11 Ereignissen in der ersten Signalregion und 17 in der zweiten ab. Diese Ergebnisse wurden mit Hinblick auf ein phänomenologisches minimal supersymmetrisches Standardmodell und auf vereinfachte supersymmetrische Modelle interpretiert. Für ein vereinfachtes Modell mit Chargino-Neutralino Paarproduktion kann der Parameterraum für Massen des leichtesten Neutralinos bis zu $\unit[100]{GeV}$ und bis zu $\unit[350]{GeV}$ für die Masse des leichtesten Charginos ausgeschlossen werden. Für ein vereinfachtes Mo\-dell mit Chargino Paarproduktion kann der Parameterraum für die leichteste Neutralinomasse bis zu $30-\unit[50]{GeV}$ in einem Bereich der leichtesten Chargino Masse von $170-\unit[330]{GeV}$ ausgeschlossen werden. Das Hauptaugenmerk dieser Arbeit liegt jedoch auf den Verfahren, die zur Bestimmung des Standardmodell-Untergrundes benutzt werden. Unterschiedliche Methoden zur Bestimmung des Untergrunds aus $Z$-Boson und Top-Quark Zerfallsprozessen wurden untersucht.

Résumé :
Cette thèse présente une étude de la production de boson de Higgs dans les collisions proton-proton à sqrt(s) = 13 TeV enregistrées avec le détecteur CMS au Grand collisionneur de hadrons (LHC) du CERN, exploitant la voie de désintégration en une paire de bosons Z qui se désintègrent à leur tour en paires d’électrons ou de muons (H->ZZ->4l, l = e,mu).Ce travail s’inscrit dans le contexte du début du Run II du LHC, une nouvelle période de prise de données qui a commencé en 2015 après une interruption de deux ans. Ce redémarrage est marqué par une augmentation de l’énergie dans le centre de masse de 8 TeV à 13 TeV et un resserrement de l’espacement entre paquets de protons de 50 ns à 25 ns. Ces nouveaux paramètres augmentent à la fois la luminosité et placent des contraintes inédites sur le déclenchement, la reconstruction et l’analyse des données de collisions pp. Un effort important est donc consacré à l’amélioration et la réoptimisation du système de déclenchement de CMS pour le Run II, en mettant l’accent sur la reconstruction et la sélection des électrons et sur la préparation de chemins de déclenchement multi-leptons préservant une efficacité maximale pour le canal H->ZZ->4l.Dans un second temps, les algorithmes de sélection hors-ligne des électrons et des muons sont optimisés et leurs efficacités sont mesurées dans les données, tandis que la logique de sélection des candidats à quatre leptons est améliorée. Afin d’extraire des modes de production rares du boson de Higgs tels que la fusion de bosons vecteurs, la production par « Higgsstrahlung » VH et la production associée ttH, une nouvelle répartition des événements sélectionnés en catégories exclusives est introduite, fondée sur des discriminants utilisant le calcul d’éléments de matrice et l’étiquetage de saveur des jets.Les résultats de l’analyse des premières données à 13 TeV sont présentés pour des lots de données enregistrés en 2015 et au début de 2016, qui correspondent à des luminosités intégrées respectives de 2.8 fb-1 and 12.9 fb-1. Le boson de Higgs est redécouvert de façon indépendante à la nouvelle énergie. L’intensité du signal relative à la prédiction du modèle standard, la masse et la largeur de désintégration du boson sont mesurées, ainsi qu’un jeu de paramètres contrôlant les contributions des principaux modes de production attendus. Tous les résultats sont en bon accord avec les prévisions du modèle standard pour un boson de Higgs à 125 GeV, aux incertitudes de mesure près, ces dernières étant dominées par la composante statistique avec l’échantillon de données actuel. Enfin, une autre résonance se désintégrant en quatre leptons est recherchée à haute masse, et aucun excès significatif n’est observé
This thesis reports a study of Higgs boson production in proton-proton collisions at sqrt(s) = 13 TeV recorded with the CMS detector at the CERN Large Hadron Collider (LHC), exploiting the decay channel into a pair of Z bosons that in turn decay into pairs of electrons or muons (H->ZZ->4l, l = e,mu).This work is carried out in the context of the beginning of Run II of the LHC, a new data-taking period that started in 2015, following a two-year-long shutdown. This restart is marked by an increase of the centre-of-mass energy from 8 TeV to 13 TeV, and a narrowing of the spacing of proton bunches from 50 ns to 25 ns. These new parameters both increase the luminosity and set new constraints on the triggering, reconstruction and analysis of pp collision events. Therefore, considerable effort is devoted to the improvement and reoptimization of the CMS trigger system for Run II, focusing on the reconstruction and selection of electrons and on the preparation of multilepton trigger paths that preserve a maximal efficiency for the H->ZZ->4l channel.Secondly, the offline algorithms for electron and muon selection are optimized and their efficiencies are measured in data, while the selection logic of four-lepton candidates is improved. In order to extract rare production modes of the Higgs boson such as vector boson fusion, VH associated production and ttH associated production, a new classification of selected events into exclusive categories is introduced, using discriminants based on matrix-element calculations and jet flavour tagging.Results of the analysis of first 13 TeV data are presented for two data sets recorded in 2015 and early 2016, corresponding to integrated luminosities of 2.8 fb-1 and 12.9 fb-1, respectively. A standalone rediscovery of the Higgs boson in the four-lepton channel is achieved at the new energy. The signal strength relative to the standard model prediction, the mass and decay width of the boson, and a set of parameters describing the contributions of its main predicted production modes are measured. All results are in good agreement with standard model expectations for a 125 GeV Higgs boson within the incertainties, which are dominated by their statistical component with the current data set. Finally, a search for an additional high-mass resonance decaying to four leptons is performed, and no significant excess is observed

Résumé :
This thesis presents a search for potential signals of new heavy resonances decaying into a pair of vector bosons, with masses between 1 TeV and 4 TeV, predicted by beyond standard model theories. The signals probed are spin-1 W', predicted by the Heavy Vector Triplet model, and spin-2 bulk gravitons, predicted by warped extra-dimension models. The scrutinized data are produced by LHC proton-proton collisions at a center-of-mass energy $\sqrt{s}=13$ TeV during the 2016 operations, and collected by the CMS experiment, corresponding to an integrated luminosity of 35.9 fbinv. One of the boson should be a Z, and it is identified through its invisible decay into neutrinos, while the other electroweak boson, consisting either into a W or into a Z boson, is required to decay hadronically into a pair of quarks. The decay products of heavy resonances are produced with large Lorentz boosts; as a consequence, the decay products of the bosons (quarks and neutrinos) are expected to be highly energetic and collimated. The couple of neutrinos, escaping undetected, is reconstructed as missing momentum in the transverse plane of the CMS detector. The couple of quarks is reconstructed as one large-cone jet, with high transverse momentum, recoiling against the couple of neutrinos. Grooming algorithms are adopted in order to improve the jet mass resolution, by removing soft radiation components and spectator events from the particles clustered as the large-cone jet. The groomed jet mass is used to tag the hadronically decaying vector boson, to define the signal region of the search (close to the nominal mass of the W and Z bosons, between 65-105 GeV) and a signal-depleted control region, that is used for the background estimation. An hybrid data-simulation approach predicts the normalization and the shape of the main background, represented by a vector boson produced in association with jets, by taking advantage of the distribution of data in the signal-depleted control regions. Secondary backgrounds are predicted from simulations. Jet substructure techniques are exploited, in order to classify events into two exclusive purity categories, by distinguishing the couple of quarks inside the large-cone jet. This approach improves the background rejection and the discovery reach. The search is performed by scanning the distribution of the reconstructed mass of the resonance, looking for a local excess in data with regards to the prediction. Depending on the mass, upper limits on the cross-section of heavy spin-1 and spin-2 narrow resonances, multiplied by the branching fraction of the resonance decaying into Z and a W boson for a spin-1 signal, and into a pair of Z bosons for spin-2, are set in the range $0.9$ -- $63$ fb and in the range $0.5$ -- $40$ fb respectively. A W' hypothesis is excluded up to 3.11 TeV, in the Heavy Vector Triplet benchmark A scenario, and up to 3.41 TeV, considering the benchmark B scenario. A bulk graviton hypothesis, given the curvature parameter of the extra-dimension $\tilde{k}=1.0$, is excluded up to 1.14 TeV.
Questa tesi presenta una ricerca di potenziali segnali di nuove risonanze pesanti, che decadono in una coppia di bosoni vettori, con masse comprese tra 1 TeV e 4 TeV, predette da teorie oltre il modello standard. I segnali indagati sono W' di spin 1, predette dal modello Heavy Vector Triplet, e gravitoni di spin 2, predetti da modelli che prevedono extra dimensioni ripiegate. I dati esaminati sono prodotti dalle collisioni protone-protone di LHC ad un'energia del centro di massa di $\sqrt{s}=13$ TeV durante le operazioni del 2016, e raccolti dall'esperimento CMS, per una luminosità integrata di 35.9 fbinv. Uno dei bosoni dev'essere una Z, che viene identificata dal suo decadimento invisibile in neutrini, mentre l'altro bosone elettrodebole, sia una W che una Z, deve decadere nel canale adronico in una coppia di quark. I prodotti di decadimento di risonanze pesanti sono generati con significativi boost di Lorentz; di conseguenza, ci si aspetta che i prodotti di decadimento dei bosoni (i quark e i neutrini) abbiano elevate energie e siano collimati. La coppia di neutrini, che sfugge alla rivelazione, viene ricostruita come momento mancante nel piano trasverso del rivelatore CMS. La coppia di quark viene ricostruita come un jet a largo cono, con elevato momento trasverso, che rincula contro la coppia di neutrini. Algoritmi di grooming sono impiegati per migliorare la risoluzione della massa del jet, rimuovendo la radiazione soffice e gli eventi spettatori dalle particelle clusterizzate come jet a largo cono. La massa ripulita del jet viene utilizzata per identificare il bosone vettore che decade in adroni, per definire la regione di segnale della ricerca (vicina alla massa nominale dei bosoni W e Z, nell'intervallo 65-105 GeV) e una regione di controllo svuotata dal segnale, che viene utilizzata per la stima dei fondi. Un approccio ibdrido dati-simulazione predice la normalizzazione e la forma del fondo principale, rappresentato da un bosone vettore prodotto in associazione con jet, sfruttando la distribuzione dei dati nelle regioni di controllo svuotate dal segnale. I fondi secondari sono predetti completamente con le simulazioni. Tecniche di sottostruttura del jet sono adoperate per classificare gli eventi in due categorie esclusive di purezza, distinguendo le coppie di quark dentro al jet a largo cono. Questo approccio migliora la soppressione del fondo e la potenzialità di scoperta. La ricerca viene fatta scansionando la distribuzione della massa ricostruita della risonanza, cercando un eccesso locale nei dati rispetto alle predizioni. In funzione della massa, limiti superiori sulla sezione d'urto per risonanze pesanti e strette di spin 1 e spin 2, moltiplicate per il rapporto di diramazione della risonanza che decade in Z e W per il segnale di spin 1, e in una coppia di bosoni Z per lo spin 2, sono fissati nell'intervallo $0.9$ -- $63$ fb e nell'intervallo $0.5$ -- $40$ fb rispettivamente. Un'ipotesi di W' e' esclusa fino ad una massa di 3.11 TeV, nello scenario A di riferimento dell'Heavy Vector Triplet, e fino a 3.41 TeV, nello scenario B di riferimento. Un'ipotesi di gravitone, dato il parametro di curvatura della dimensione addizionale $\tilde{k}=1.0$, è esclusa fino ad una massa di 1.14 TeV.

Résumé :
AbstractIn this chapter, we examine the association between forgiveness and flourishing. We begin by identifying what forgiveness and flourishing are. We then move to considering conceptual models as well as evidence supporting the connection between forgiveness and flourishing. An early model of the forgiveness and mental health relationship offers a beginning in this regard. Next, we examine the stress-and-coping models of forgiveness of oneself and others. The final model is the scaffolding self and social systems model of forgiveness and subjective well-being. These models offer multiple vantage points from which to consider the forgiveness-flourishing connection. Limitations to these models and to the current state of knowledge on forgiveness and flourishing are highlighted, especially the limits to comprehensive assessment of flourishing in the extant literature. Conclusions and future directions for studying and promoting flourishing in people of different religious affiliation, cultures, countries, and life-circumstances are discussed in closing.

Résumé :
AbstractAustralia, like many countries, has a history of colonisation and extensive controlled and humanitarian immigration, with this shifting from an Anglo-Celtic emphasis to include, in succession, an emphasis on migrants from Europe, Asia and Africa. This chapter provides several perspectives on evidence-based school development in this changing context. The first focus is on national school-wide improvement initiatives: IDEAS (Innovative Designs for Enhancing Achievements in Schools), which utilises professional learning communities to improve student outcomes; and PALL (Principals as Literacy Leaders) which provides principals with literacy and leadership knowledge to support teachers to improve student reading performance. The second perspective explores the state level through considering work at the Melbourne Graduate School of Education in terms of evidence-based teacher training through the development of a clinical teaching model, and evidence-based school improvement through the Science of Learning Schools Partnership. The final perspective is at the school level, where the development of two schools in challenging contexts are described: the first a school formed from the closure of three failing schools; the second a school that was at the point of closure when the current principal was appointed to turn-it-around.

Résumé :
AbstractInfrastructure as Code is a new approach to computing infrastructure management that allows users to leverage tools such as version control, automatic deployments, and program analysis for infrastructure configurations. This approach allows for faster and more homogeneous configuration of a complete infrastructure. Infrastructure as Code languages, such as CloudFormation or TerraForm, use a declarative model so that users only need to describe the desired state of the infrastructure. However, in practice, these languages are not processed atomically. During an upgrade, the infrastructure goes through a series of intermediate states. We identify a security vulnerability that occurs during an upgrade even when the initial and final states of the infrastructure are secure, and we show that those vulnerability are possible in Amazon’s AWS and Google Cloud. We call such attacks intra-update sniping vulnerabilities. In order to mitigate this shortcoming, we present a technique that detects such vulnerabilities and pinpoints the root causes of insecure deployment migrations. We implement this technique in a tool, Häyhä, that uses dataflow graph analysis. We evaluate our tool on a set of open-source CloudFormation templates and find that it is scalable and could be used as part of a deployment workflow.

Résumé :
AbstractLarge distributed systems with an emphasis on adaptability are now considered a necessity in many domains, yet reconfiguration of these systems is still largely carried out in an ad hoc fashion, a process that is both inefficient and error-prone. In this paper, we tackle the planification problem for the reconfiguration of distributed systems in the component-based reconfiguration model Concerto. Specifically, given some tasks to execute and a desired final state of the system, we show how to compute a reconfiguration plan that guarantees satisfaction of inter-component dependencies and is also optimized for parallel execution. Our technique relies on an SMT solver to compute the required dependencies between components and ultimately schedule the reconfiguration. We illustrate the use of this technique on a variety of synthetic examples as well as a real use case in the context of an OpenStack system.

Résumé :
With the goal in mind to separate final state effects due to the interaction of the ejected electron with the laser field from dynamical effects associated with the process of ionization, we investigate the following simple model: We assume an effective interaction that just lifts the electron into the continuum via absorption of the minimum number N of photons which is necessary to overcome the ionization potential (defined in the absence of the field). The effective interaction is left unspecified except its matrix element is assumed to be proportional to IN/2 with I the intensity of the laser field. As soon as the electron is free we assume it only feels the laser field and, consequently, is described by the so-called Volkov solution which provides an exact solution for an electron in an external plane wave field. For simplicity, we also adopt the long wavelength approximation for the laser field. For the initial atom and the final ion we take the unperturbed wave functions and we also disregard the recoil imparted to the ion. Altogether, this is essentially the Keldysh approximation. It turns out that boundary conditions, i.e. the way the electrons leaves the laser pulse, are of vital importance.1 In order to explain the experimentally observed absence of intensity-dependent shifts in the electron spectra we have to assume that the electron leaves the electron pulse on the side rather than being passed over by the pulse. Under these conditions, we also obtain the total suppression of the low-lying peaks of the electron distribution with increasing intensity which is impressively born out by recent experiments.2,3 The mechanism can be ascribed to the ponderomotive potential which adds to the ionization potential. When the electron leaves the pulse on one side the energy corresponding to the ponderomotive potential is converted into kinetic energy.4

Résumé :
The Sobrato Early Academic Language (SEAL) Model Research and Evaluation Final Report is comprised of three sets of studies that took place between 2015 and 2019 to examine the effectiveness of the SEAL Model in 67 schools within 12 districts across the state of California. Over a decade ago, the Sobrato Family Foundation responded to the enduring opportunity gaps and low academic outcomes for the state’s 1.2 million English Learners by investing in the design of the SEAL Model. The SEAL PreK–Grade 3 Model was created as a whole-school initiative to develop students’ language, literacy, and academic skills. The pilot study revealed promising findings, and the large-scale implementation of SEAL was launched in 2013. This report addresses a set of research questions and corresponding studies focused on: 1) the perceptions of school and district-level leaders regarding district and school site implementation of the SEAL Model, 2) teachers’ development and practices, and 3) student outcomes. The report is organized in five sections, within which are twelve research briefs that address the three areas of study. Technical appendices are included in each major section. A developmental evaluation process with mixed methods research design was used to answer the research questions. Key findings indicate that the implementation of the SEAL Model has taken root in many schools and districts where there is evidence of systemic efforts or instructional improvement for the English Learners they serve. In regards to teachers’ development and practices, there were statistically significant increases in the use of research-based practices for English Learners. Teachers indicated a greater sense of efficacy in addressing the needs of this population and believe the model has had a positive impact on their knowledge and skills to support the language and literacy development of PreK- Grade 3 English Learners. Student outcome data reveal that despite SEAL schools averaging higher rates of poverty compared to the statewide rate, SEAL English Learners in grades 2–4 performed comparably or better than California English Learners in developing their English proficiency; additional findings show that an overwhelming majority of SEAL students are rapidly progressing towards proficiency thus preventing them from becoming long-term English Learners. English Learners in bilingual programs advanced in their development of Spanish, while other English Learners suffered from language loss in Spanish. The final section of the report provides considerations and implications for further SEAL replication, sustainability, additional research and policy.

Résumé :
ERDC-Geo is a surface erodibility parameterization developed to improve dust predictions in weather forecasting models. Geomorphic landform maps used in ERDC-Geo link surface dust emission potential to landform type. Using a previously generated southwest United States landform map as training data, a classification model based on machine learning (ML) was established to generate ERDC-Geo input data. To evaluate the ability of the ML model to accurately classify landforms, an independent reference landform data set was created for areas in the Chihuahuan Desert. The reference landform data set was generated using two separate map-ping methodologies: one based on in situ observations, and another based on the interpretation of satellite imagery. Existing geospatial data layers and recommendations from local rangeland experts guided site selections for both in situ and remote landform identification. A total of 18 landform types were mapped across 128 sites in New Mexico, Texas, and Mexico using the in situ (31 sites) and remote (97 sites) techniques. The final data set is critical for evaluating the ML-classification model and, ultimately, for improving dust forecasting models.
