Search for Higgs Boson Production Beyond the Standard Model Using the Razor Kinematic Variables in pp Collisions at √s=8 TeV and Optimization of Higgs Boson Identification Using a Quantum Annealer

In the first part of this thesis we search for beyond the Standard Model physics through the search for anomalous production of the Higgs boson using the razor kinematic variables. We search for anomalous Higgs boson production using proton-proton collisions at center of mass energy √s=8 TeV collected by the Compact Muon Solenoid experiment at the Large Hadron Collider corresponding to an integrated luminosity of 19.8 fb^-1.

In the second part we present a novel method for using a quantum annealer to train a classifier to recognize events containing a Higgs boson decaying to two photons. We train that classifier using simulated proton-proton collisions at √s=8 TeV producing either a Standard Model Higgs boson decaying to two photons or a non-resonant Standard Model process that produces a two photon final state.

The production mechanisms of the Higgs boson are precisely predicted by the Standard Model based on its association with the mechanism of electroweak symmetry breaking. We measure the yield of Higgs bosons decaying to two photons in kinematic regions predicted to have very little contribution from a Standard Model Higgs boson and search for an excess of events, which would be evidence of either non-standard production or non-standard properties of the Higgs boson. We divide the events into disjoint categories based on kinematic properties and the presence of additional b-quarks produced in the collisions. In each of these disjoint categories, we use the razor kinematic variables to characterize events with topological configurations incompatible with typical configurations found from standard model production of the Higgs boson.

We observe an excess of events with di-photon invariant mass compatible with the Higgs boson mass and localized in a small region of the razor plane. We observe 5 events with a predicted background of 0.54 ± 0.28, which observation has a p-value of 10^-3 and a local significance of 3.35σ. This background prediction comes from 0.48 predicted non-resonant background events and 0.07 predicted SM higgs boson events. We proceed to investigate the properties of this excess, finding that it provides a very compelling peak in the di-photon invariant mass distribution and is physically separated in the razor plane from predicted background. Using another method of measuring the background and significance of the excess, we find a 2.5σ deviation from the Standard Model hypothesis over a broader range of the razor plane.

In the second part of the thesis we transform the problem of training a classifier to distinguish events with a Higgs boson decaying to two photons from events with other sources of photon pairs into the Hamiltonian of a spin system, the ground state of which is the best classifier. We then use a quantum annealer to find the ground state of this Hamiltonian and train the classifier. We find that we are able to do this successfully in less than 400 annealing runs for a problem of median difficulty at the largest problem size considered. The networks trained in this manner exhibit good classification performance, competitive with the more complicated machine learning techniques, and are highly resistant to overtraining. We also find that the nature of the training gives access to additional solutions that can be used to improve the classification performance by up to 1.2% in some regions.

Evoluzione dell'ente training center: il caso Automobili Lamborghini S.p.a

La presente tesi, redatta durante un tirocinio presso l’azienda Automobili Lamborghini S.p.a., ha come fine ultimo la descrizione di attività volte all’evoluzione dell’ente Training Center facente parte dell’area industriale. L’ente Training center è responsabile dell'organizzazione, dell'erogazione e del monitoraggio della formazione incentrata sulle cosiddette technical skills utili per il miglioramento o il rafforzamento delle competenze e delle conoscenze tecniche degli operatori. La prima attività descritta ha lo scopo di creare un database contenente tutte le competenze che ogni operatore deve possedere per poter lavorare autonomamente su una determinata stazione di lavoro al fine di individuare il gap di competenze. L’analisi condotta ha come obiettivi: la pianificazione strategica della forza lavoro, la mappatura dell’intera organizzazione, l’implementazione (ove necessario) di nuovi training, l’aumento della produttività, e l’aumento della competitività aziendale. In seguito, è stata svolta un’analisi delle matrici di flessibilità, ovvero delle matrici che forniscono informazioni su quanti blue collars sono in grado di lavorare su determinate stazioni e in quale ruolo (operatore in training, operatore autonomo o operatore specializzato e quindi in grado di assumere il ruolo di trainer). Studiando tali matrici sono state identificate delle regole che rendono il processo di training on the job il più efficace ed efficiente possibile con o scopo, da una parte di evitare eccessive ore di training e quindi eccessivo dispendio economico, dall’altra, quello di riuscire a coprire tutte le stazioni considerando i picchi di assenteismo della forza lavoro. Infine, si è rivelata necessaria l’implementazione di un nuovo training, il “train the tutor”, ovvero un percorso di formazione riservato ai dipendenti potenzialmente in grado di insegnare attività in cui loro sono specializzati ad operatori in training.

Gastroenterology training in Latin America

Latin America is characterized by ethnic, geographical, cultural, and economic diversity; therefore, training in gastroenterology in the region must be considered in this context. The continent's medical education is characterized by a lack of standards and the volume of research continues to be relatively small. There is a multiplicity of events in general gastroenterology and in sub-disciplines, both at regional and local levels, which ensure that many colleagues have access to information. Medical education programs must be based on a clinical vision and be considered in close contact with the patients. The programs should be properly supervised, appropriately defined, and evaluated on a regular basis. The disparity between the patients' needs, the scarce resources available, and the pressures exerted by the health systems on doctors are frequent cited by those complaining of poor professionalism. Teaching development can play a critical role in ensuring the quality of teaching and learning in universities. Continuing professional development programs activities must be planned on the basis of the doctors' needs, with clearly defined objectives and using proper learning methodologies designed for adults. They must be evaluated and accredited by a competent body, so that they may become the basis of a professional regulatory system. The specialty has made progress in the last decades, offering doctors various possibilities for professional development. The world gastroenterology organization has contributed to the speciality through three distinctive, but closely inter-related, programs: Training Centers, Train-the-Trainers, and Global Guidelines, in which Latin America is deeply involved.

Use of Medical Subject Headings (MeSH) in Portuguese for categorizing web-based healthcare content

Introduction: Internet users are increasingly using the worldwide web to search for information relating to their health. This situation makes it necessary to create specialized tools capable of supporting users in their searches. Objective: To apply and compare strategies that were developed to investigate the use of the Portuguese version of Medical Subject Headings (MeSH) for constructing an automated classifier for Brazilian Portuguese-language web-based content within or outside of the field of healthcare, focusing on the lay public. Methods: 3658 Brazilian web pages were used to train the classifier and 606 Brazilian web pages were used to validate it. The strategies proposed were constructed using content-based vector methods for text classification, such that Naive Bayes was used for the task of classifying vector patterns with characteristics obtained through the proposed strategies. Results: A strategy named InDeCS was developed specifically to adapt MeSH for the problem that was put forward. This approach achieved better accuracy for this pattern classification task (0.94 sensitivity, specificity and area under the ROC curve). Conclusions: Because of the significant results achieved by InDeCS, this tool has been successfully applied to the Brazilian healthcare search portal known as Busca Saude. Furthermore, it could be shown that MeSH presents important results when used for the task of classifying web-based content focusing on the lay public. It was also possible to show from this study that MeSH was able to map out mutable non-deterministic characteristics of the web. (c) 2010 Elsevier Inc. All rights reserved.

Support vector machines for detecting age-related changes in running kinematics

Age-related changes in running kinematics have been reported in the literature using classical inferential statistics. However, this approach has been hampered by the increased number of biomechanical gait variables reported and subsequently the lack of differences presented in these studies. Data mining techniques have been applied in recent biomedical studies to solve this problem using a more general approach. In the present work, we re-analyzed lower extremity running kinematic data of 17 young and 17 elderly male runners using the Support Vector Machine (SVM) classification approach. In total, 31 kinematic variables were extracted to train the classification algorithm and test the generalized performance. The results revealed different accuracy rates across three different kernel methods adopted in the classifier, with the linear kernel performing the best. A subsequent forward feature selection algorithm demonstrated that with only six features, the linear kernel SVM achieved 100% classification performance rate, showing that these features provided powerful combined information to distinguish age groups. The results of the present work demonstrate potential in applying this approach to improve knowledge about the age-related differences in running gait biomechanics and encourages the use of the SVM in other clinical contexts.

La visite médicale en pratique hospitalière: entre soins et apprentissage [Conducting ward rounds: a balance between care and teaching].

Every day, hospital doctors spend time at conducting ward rounds. Rounds are a core clinical activity during which doctors interact with patients, synthetise a whole set of informations and make many decisions. In addition, rounds can become a crucial teaching moment, when a trainee gets supervised by an attending physician. However, litterature on the topic of rounds is scarce. This paper summarizes the results of the few key studies focusing on ward rounds. The results are presented in four sections, each one being dedicated to one of the round stakeholders: the trainee or resident, the trainer, the patient and the nurse. An emphasis is put on ward rounds involving both a trainee and a trainer, since such rounds always mean striking a balance between care and teaching.

Distinguishing general concepts from individuals: an automatic coarse-grained classifier

Named entity recognizers are unable to distinguish if a term is a general concept as "scientist" or an individual as "Einstein". In this paper we explore the possibility to reach this goal combining two basic approaches: (i) Super Sense Tagging (SST) and (ii) YAGO. Thanks to these two powerful tools we could automatically create a corpus set in order to train the SuperSense Tagger. The general F1 is over 76% and the model is publicly available.

Public Employees Leadership Institute Final Report, August 2011

Public agencies in Iowa are continually challenged with reduced staff levels, reduced budgets, and increased expectations for services provided. Responding to these demands requires a well-informed and coordinated team that includes professionals, supervisors, technicians, lead workers, and workers. Becoming a coordinated team requires the training and interaction to produce a common foundation to build upon. In 2007, a training program did not exist in the state to provide this level of training for existing or upcoming managers and leaders of public agencies. The Iowa Local Technical Assistance Program (LTAP), in conjunction with Iowa public agency representatives, set out to provide that foundation by developing the Iowa Public Employees Leadership Academy, which was renamed the Public Employees Leadership Institute in July 2011. The Institute is an on-demand, online training program designed to create better (or new) leaders and supervisors for Iowa’s public agencies. The Institute provides a curriculum to train the next generation of leaders, who will replace existing leaders when retirements occur. Through the Institute, Iowa LTAP will provide a coordinated, structured, non-credit educational program available for a modest fee. The techniques and skills offered through the Institute can apply to all who wish to develop or sharpen their leadership and management abilities. This will be true whether the participants are employed in the public or private sector. The 14 courses that were developed and are being offered are as follows: Supervisory Techniques and Skills, Team Development, Communications Skills, Leadership Skills, Community Service/Customer Orientation, Legal Understanding, Fundamentals of Government, Finance, Resource Management, Operations and Maintenance, Basic Management, Emergency Management, Project Management, and Winter Maintenance Management.

Impacte de la Gimnàstica artística a Vic: la relació gimnasta-entrenadora dins del Club Gimnàstic Osona (CGO)

L’objectiu d’aquest estudi és comprovar si una millor relació entre gimnasta i entrenadora és un factor determinant per a poder obtenir més resultats en les competicions. S’estudien tres grups dividits per tres nivells diferents: Escolar (8 gimnastes), Promogym (11 gimnastes) i Tecnificació (28 gimnastes). A partir d’una adaptació feta dels qüestionaris Cart-Q de Jowett i Ntoumanis (2004) i l’ SF-PANAS de Thompson (2007) es realitzarà l’anàlisi de la relació gimnasta-entrenadora abans de dues competicions, on s’analitzaran els podis. Observant l’estudi, una baixada de mitjanes dels aspectes de les 3 C’s (proximitat, compromís i complementarietat) estava acompanyat d’una baixada de resultats i una pujada de les mitjanes de les 3 C’s estava relacionat amb l’obtenció de més podis. Per tant, a l’hora de valorar els resultats en competició la relació gimnasta-entrenadora és un factor important a tenir en compte.
