The goal of this report is to give a comprehensive overview of the rich field of forward physics, with a special attention to the topics that can be studied at the LHC. The report starts presenting a selection of the Monte Carlo simulation tools currently available, chapter 2, then enters the rich phenomenology of QCD at low, chapter 3, and high, chapter 4, momentum transfer, while the unique scattering conditions of central exclusive production are analyzed in chapter 5. The last two experimental topics, Cosmic Ray and Heavy Ion physics are presented in the chapter 6 and 7 respectively. Chapter 8 is dedicated to the BFKL dynamics, multiparton interactions, and saturation. The report ends with an overview of the forward detectors at LHC. Each chapter is correlated with a comprehensive bibliography, attempting to provide to the interested reader with a wide opportunity for further studies.

Thermal comfort has become a topic issue in building performance assessment as well as energy efficiency. Three methods are mainly recognized for its assessment. Two of them based on standardized methodologies, face the problem by considering the indoor environment in steady-state conditions (PMV and PPD) and users as active subjects whose thermal perception is influenced by outdoor climatic conditions (adaptive approach). The latter method is the starting point to investigate thermal comfort from an overall perspective by considering endogenous variables besides the traditional physical and environmental ones. Following this perspective, the paper describes the results of an in-field investigation of thermal conditions through the use of nearable and wearable solutions, parametric models and machine learning techniques. The aim of the research is the exploration of the reliability of IoT-based solutions combined with advanced algorithms, in order to create a replicable framework for the assessment and improvement of user thermal satisfaction. For this purpose, an experimental test in real offices was carried out involving eight workers. Parametric models are applied for the assessment of thermal comfort; IoT solutions are used to monitor the environmental variables and the users' parameters; the machine learning CART method allows to predict the users' profile and the thermal comfort perception respect to the indoor environment.

We discuss the discovery potential of light-by-light scattering at the Large Hadron Collider (LHC), induced by the Standard Model (SM) and by new exotic charged particles. Our simulation relies on intact proton detection in the planned forward detectors of CMS and ATLAS. The full four-photon amplitudes generated by any electrically charged particles of spins $1/2$ and $1$, including the SM processes involving loops of leptons, quarks and $W$ bosons are implemented in the Forward Physics Monte Carlo generator. Our method provides model-independent bounds on massive charged particles, only parametrized by the spin, mass and "effective charge" $Q_{\rm eff}$ of the new particle. We find that a new charged vector (fermion) with $Q_{\rm eff}=4$ can be discovered up to $m=640~\rm GeV$ ($m=300~\rm GeV$) with an integrated luminosity of $300~\rm fb^{-1}$ at the LHC. We also discuss the sensitivities to neutral particles such as a strongly-interacting heavy dilaton and warped Kaluza-Klein gravitons, whose effects could be discovered for masses in the multi-TeV range.

The sensitivities to anomalous quartic photon couplings at the Large Hadron Collider are estimated using diphoton production via photon fusion. The tagging of the protons proves to be a very powerful tool to suppress the background and unprecedented sensitivities down to $7\ifmmode\times\else\texttimes\fi{}1{0}^{\ensuremath{-}15}\text{ }{\mathrm{GeV}}^{\ensuremath{-}4}$ are obtained, providing a new window on extra dimensions and strongly interacting composite states in the multi-TeV range. Generic contributions to quartic photon couplings from charged and neutral particles with arbitrary spin are also presented.

For the high luminosity upgrade of the LHC at CERN, ATLAS is considering the addition of a High Granularity Timing Detector (HGTD) in front of the end cap and forward calorimeters at |z|= 3.5 m and covering the region 2.4 <|η|< 4 to help reducing the effect of pile-up. The chosen sensors are arrays of 50 μm thin Low Gain Avalanche Detectors (LGAD). This paper presents results on single LGAD sensors with a surface area of 1.3×1.3 mm2 and arrays with 2×2 pads with a surface area of 2×2 mm2 or 3×3 mm2 each and different implant doses of the p+ multiplication layer. They are obtained from data collected during a beam test campaign in autumn 2016 with a pion beam of 120 GeV energy at the CERN SPS. In addition to several quantities measured inclusively for each pad, the gain, efficiency and time resolution have been estimated as a function of the position of the incident particle inside the pad by using a beam telescope with a position resolution of few μm. Different methods to measure the time resolution are compared, yielding consistent results. The sensors with a surface area of 1.3×1.3 mm2 have a time resolution of about 40 ps for a gain of 20 and of about 27 ps for a gain of 50 and fulfil the HGTD requirements. Larger sensors have, as expected, a degraded time resolution. All sensors show very good efficiency and time resolution uniformity.

Thermal comfort is traditionally assessed by using the PMV index defined according to the EN ISO 7730:2005 where the user passively interacts with the surrounding environment considering a physic-based model built on a steady-state thermal energy balance equation. The thermal comfort satisfaction is a holistic concept comprising behavioral, physiological and psychological aspects. This article describes a workflow for the assessment of the thermal conditions of users through the analysis of their specific psychophysical conditions overcoming the limitation of the physic-based model in order to investigate and consider other possible relations between the subjective and objective variables.

Charged-pion-interferometry measurements were made with respect to the second- and third-order event plane for $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\mathrm{GeV}$. A strong azimuthal-angle dependence of the extracted Gaussian-source radii was observed with respect to both the second- and third-order event planes. The results for the second-order dependence indicate that the initial eccentricity is reduced during the medium evolution, which is consistent with previous results. In contrast, the results for the third-order dependence indicate that the initial triangular shape is significantly reduced and potentially reversed by the end of the medium evolution, and that the third-order oscillations are largely dominated by the dynamical effects from triangular flow.

Results are presented of a search for particles decaying into final states with significant missing transverse momentum and exactly two identical flavour leptons (e, μ) of opposite charge in $\sqrt{s}=7$ TeV collisions at the Large Hadron Collider. This channel is particularly sensitive to supersymmetric particle cascade decays producing flavour correlated lepton pairs. Flavour uncorrelated backgrounds are subtracted using a sample of opposite flavour lepton pair events. Observation of an excess beyond Standard Model expectations following this subtraction procedure would offer one of the best routes to measuring the masses of supersymmetric particles. In a data sample corresponding to an integrated luminosity of 35 pb−1 no such excess is observed. Model-independent limits are set on the contribution to these final states from supersymmetry and are used to exclude regions of a phenomenological supersymmetric parameter space.

Virtual reality (VR) headsets, with embedded micro-electromechanical systems, have the potential to assess the mechanical heart’s functionality and respiratory activity in a non-intrusive way and without additional sensors by utilizing the ballistocardiographic principle. To test the feasibility of this approach for opportunistic physiological monitoring, thirty healthy volunteers were studied at rest in different body postures (sitting (SIT), standing (STAND) and supine (SUP)) while accelerometric and gyroscope data were recorded for 30 s using a VR headset (Oculus Go, Oculus, Microsoft, USA) simultaneously with a 1-lead electrocardiogram (ECG) signal for mean heart rate (HR) estimation. In addition, longer VR acquisitions (50 s) were performed under controlled breathing in the same three postures to estimate the respiratory rate (RESP). Three frequency-based methods were evaluated to extract from the power spectral density the corresponding frequency. By the obtained results, the gyroscope outperformed the accelerometer in terms of accuracy with the gold standard. As regards HR estimation, the best results were obtained in SIT, with Rs2 (95% confidence interval) = 0.91 (0.81−0.96) and bias (95% Limits of Agreement) −1.6 (5.4) bpm, followed by STAND, with Rs2 = 0.81 (0.64−0.91) and −1.7 (11.6) bpm, and SUP, with Rs2 = 0.44 (0.15−0.68) and 0.2 (19.4) bpm. For RESP rate estimation, SUP showed the best feasibility (98%) to obtain a reliable value from each gyroscope axis, leading to the identification of the transversal direction as the one containing the largest breathing information. These results provided evidence of the feasibility of the proposed approach with a degree of performance and feasibility dependent on the posture of the subject, under the conditions of keeping the head still, setting the grounds for future studies in real-world applications of HR and RESP rate measurement through VR headsets.

A search is presented for a high mass neutral particle that decays directly to the e ± μ ∓ final state. The data sample was recorded by the ATLAS detector in $\sqrt{s}=7\mbox{~TeV}$ pp collisions at the LHC from March to June 2011 and corresponds to an integrated luminosity of 1.07 fb−1. The data are found to be consistent with the Standard Model background. The high e ± μ ∓ mass region is used to set 95% confidence level upper limits on the production of two possible new physics processes: tau sneutrinos in an R-parity violating supersymmetric model and Z′-like vector bosons in a lepton flavor violating model.

Epithelial ovarian cancer (EOC) is the most lethal gynecological cancer. Several hospitals throughout the region provide primary treatment for these patients and it is well know that treatment quality is correlated to the hospital that delivers. The aim of this study was to investigate the management and treatment of EOC in a Region of the North Italy (Emilia-Romagna, Italy). A multidisciplinary group made up of 11 physicians and 3 biostatisticians was formed in 2009 to perform clinical audits in order to identify quality indicators and to develop Region-wide workup in accordance with the principles of evidence-based medicine (EBM). The rationale was that, by setting up an oncogynecology network so as to achieve the best clinical practice, critical points would decrease or even be eliminated. Analysis of cases was based on the review of the medical records. 614 EOC patients treated between 2007 and 2008 were identified. We found only 2 high-volume hospitals (≥ 21 patients/year), 3 medium-volume hospitals (11–20 operated patients/year), and 7 low-volume hospitals (≤ 10 operated patients /year). Only 222 patients (76.3%) had a histological diagnosis, FIGO surgical staging was reported only in 206 patients (70.9%) but not all standard surgical procedures were always performed, residual disease were not reported in all patients. No standard number of neoadjuvant chemotherapy cycles was observed. The differences in terms of treatments provided led the multidisciplinary group to identify reference centers, to promote centralization, to ensure uniform and adequate treatment to patients treated in regional centers and to promote a new audit involving all regional hospitals to a complete review of the all the EOC patients.

Positively advocating that low-cost additive 3D-printing technologies and open-source licensed software/hardware platforms represent an optimal solution to realize low-cost equipment, a mechanical and 3D-printable device for bilateral upper-limb rehabilitation is presented. The design and manufacturing process of this wheel-geared mechanism, enabling in-phase and anti-phase movements, will be openly provided online with the aim of making a set of customizable devices for neurorehabilitation exploitable all over the world even by people/countries with limited economical and technological resources. In order to characterize the interaction with the device, preliminary trials with EMG and kinematics recordings were performed on healthy subjects.

A search for new spin-0 resonances decaying into two photons in the ATLAS experiment at the LHC is described. The analysis is based on $pp$ collision data at $\sqrt{s}$=13 TeV corresponding to integrated luminosities of 3.2/fb and 12.2/fb recorded in 2015 and 2016, respectively. A deviation from the Standard Model background-only hypothesis corresponding to 3.4 standard deviations is observed in the 2015 data for a resonance mass hypothesis of 730 GeV. No significant excess at such mass over the background expectation is observed in the 2016 data. Limits on the production cross section times branching ratio to two photons of such resonances are reported.

Cette these porte sur l'evaluation du potentiel de decouverte du boson de Higgs par sa desintegration en quatre leptons (electrons et muons) dans l'experience ATLAS aupres du LHC. Le LHC a ete construit pour accelerer des faisceaux de protons a une energie dans le centre de masse de 14~TeV. Son programme de physique a commence avec des collisions a 7~TeV au debut de l'annee 2010. Deux analyses sont presentees : une analyse inclusive visant tous les modes de production du boson Higgs et une analyse exclusive specifique a la production par fusion de bosons vecteurs (VBF), etudiee pour la premiere fois dans la collaboration. Toutes deux permettent la decouverte du boson de Higgs apres quelques annees de fonctionnement du LHC, avec une luminosite integree de 30~fb[dollar]^{-1}[dollar]. La premiere couvre la plus grande partie d'une fenetre en masse du Higgs allant de 130 a 500~GeV. La deuxieme est focalisee sur des masses de 180~GeV ou plus et utilise la presence de jets de grande ellergie et relativement separes en pseudo-rapidite pour augmenter le rapport signal sur bruit. Une partie importante de ce document est consacree a la reconstruction de l'isolation et de la perte d'energie des muons dans les calorimetres d'ATLAS. Un outil pour l'identification des depots d'energie a ete developpe et teste avec des donnees simulees et des muons cosmiques. Ceci a conduit a une amelioration de la resolution en impulsion des muons et de la separation entre muons provenant de la desintegration des quarks lourds et des bosons vecteurs. Le dernier resultat devrait aboutir a une reduction proche d'un facteur deux du bruit de fond [dollar]Z\bbar[dollar], l'un des fonds dominants pour le canal [dollar]H \to 4\mu[dollar].

Muons in the ATLAS detector are reconstructed by combining the information from the two tracking devices: the Inner Detector and the Muon Spectrometer (MS), located in the outermost part of the experiment. Until they reach the MS, muons traverse typically 100 radiation lengths (X0) of material, most part instrumented by the electromagnetic and hadronic calorimeters. The proper account for multiple scattering and energy loss effects is essential for the reconstruction and the use of the calorimeter measurement can improve the transverse momentum resolution, specially in case of high energy deposits. On the other hand, the calorimeter activity around a muon, or conversely its isolation, is one of the most powerful features to distinguish W and Z decays from semi-leptonic decays of heavy flavour mesons (containing b and c quarks). The principle of the software package that performs these tasks, called TrackInCaloTools is presented together with the expected performance in physics analyses.

We present the midrapidity charged pion invariant cross sections and the ratio of $\pi^-$-to-$\pi^+$ production ($5<p_T<13$ GeV/$c$), together with the double-helicity asymmetries ($5<p_T<12$ GeV/$c$) in polarized $p$$+$$p$ collisions at $\sqrt{s} = 200$ GeV. The cross section measurements are consistent with perturbative calculations in quantum chromodynamics within large uncertainties in the calculation due to the choice of factorization, renormalization, and fragmentation scales. However, the theoretical calculation of the ratio of $\pi^-$-to-$\pi^+$ production when considering these scale uncertainties overestimates the measured value, suggesting further investigation of the uncertainties on the charge-separated pion fragmentation functions is needed. Due to cancellations of uncertainties in the charge ratio, direct inclusion of these ratio data in future parameterizations should improve constraints on the flavor dependence of quark fragmentation functions to pions. By measuring charge-separated pion asymmetries, one can gain sensitivity to the sign of $\Delta G$ through the opposite sign of the up and down quark helicity distributions in conjunction with preferential fragmentation of positive pions from up quarks and negative pions from down quarks. The double-helicity asymmetries presented are sensitive to the gluon helicity distribution over an $x$ range of $\sim$0.03--0.16.

The properties of the Higgs boson measured in bosonic decay channels ($H \rightarrow \gamma\gamma$, $H \rightarrow ZZ^* \rightarrow 4\ell$, $H \rightarrow WW^{*} \rightarrow \ell\nu\ell\nu$, $H \rightarrow Z\gamma$) with 25 fb$^{-1}$ of pp collision data from the Large Hadron Collider run-1 collected by the ATLAS experiment are presented. The results include an improved measurement of the mass of the Higgs boson from a combined fit to the invariant mass spectra of the decay channels $H \rightarrow \gamma\gamma$ and $H \rightarrow ZZ^* \rightarrow 4\ell$, which yields $m_H = 125.36 \pm 0.37$ (stat) $\pm 0.18$ (syst) GeV = $125.36 \pm 0.41$ GeV and supersedes the previous result from ATLAS.

Com a estreia de um novo Star Wars vem um convite que preciso aceitar, em colocar os meus pensamentos e reflexoes sobre esta saga, seus herois e suas jornadas. Por muitos anos tenho acompanhado a producao da saga e do mito, sempre em dialogo com Joseph Campbell e o conhecimento da jornada do heroi. Com o episodio VII da saga, surgem reflexoes e a oportunidade de embarcarmos na nossa jornada mitica. E um momento de tumulto no contexto das personagens, o medo, a repressao, a ganância e o controle estao presentes no cotidiano. Uma figura sinistra, apoiada por um regime totalitarista, lidera o movimento de extincao das diferencas, em prol da homogeneidade social. Uma batalha entre o orgânico e o mecânico, a tecnologia contra a natureza. Contra esta forca, um grupo de resistencia batalha pela liberdade, pela democracia e pela heterogeneidade. Estas sao as forcas motoras e opostas em jogo: a ordem pelo medo, representada pela Primeira Ordem e a liberdade pela democracia, representada pela Resistencia da Republica. E neste momento e contexto que uma figura humilde, de vida simples que e desafiada a participar de algo maior que ele, o inicio de sua jornada mitica. O heroi precisa escolher algo que ele nunca tinha imaginado para si, naturalmente ele resiste, tem medo, acredita que nao faz parte do fluxo do universo, esta a margem e impotente. Mas atraves de sua conexao com os outros, de sua compaixao, ele encontra companheiros e da os primeiros passos em direcao a aventura. Logo a missao se apresenta como vital a sobrevivencia da galaxia e novamente o heroi se percebe impotente frente a tamanho compromisso. Este e o momento para o encontro com o mestre anciao, um velho marcado pelo tempo, de humor facil. O mestre inspira o heroi com historias de grandes aventuras, de como todos estamos conectados no universo, de um poder especial, que nos faz maiores que nos mesmos, que pode ser usado para o bem, ou para o mal. Mas e apenas com o choque de realidade, de que tudo o que o heroi conhece e ama sera destruido, que ele se liberta do medo. A partir deste momento o heroi desenvolve habilidades e finalmente se encontra com sua sombra, um heroi caido, seduzido pelo caminho mais facil, de controle e medo. Como licao final o mestre atua com amor perante a sombra e se sacrifica pelo heroi. Mesmo em luto pela perda de seu mestre, o heroi precisa enfrentar a sombra e aprender com ela. A sombra e tentadora, ela oferece poderes inimaginaveis ao heroi, busca corrompe-lo e converte-lo para a escuridao, reprimindo sua humanidade, sua compaixao e sentimentos, pela promessa de ordem e paz. O heroi e tentado, mas o sacrificio do mestre o encoraja a escolher pelo caminho da luz. Ele preserva sua humanidade e atua com compaixao. Ele dissolve as trevas com sua luz. Transbordado de amor, esperanca e confianca o heroi sai do encontro elevado, transformado. Ele agora alcancou um novo conhecimento, que traz esperanca para o desenvolvimento de todos, em um compromisso com o todo. Se a leitura inspira ou causa medo e recusa, e por que todos nos vivemos diariamente os convites, recusas e aceites as aventuras miticas que compoem nossas vidas. Em uma escala cinematografica, a saga Star Wars , trata de pessoas simples, humildes, sem poderes especiais, como qualquer um de nos e de como podemos nos desenvolver em nossas jornadas. Quando estamos atentos ao nosso contexto podemos perceber os convites que recebemos, refletir sobre o quao nos sentimos preparados para embarcar naquela aventura, se fazemos parte do todo, ou se ainda nos sentimos a margem dos grandes acontecimentos humanos. Quando, atraves de nossa compaixao, pudermos escolher por nos conectarmos aos outros a nossa volta e nos percebermos como parte vital da vida terrena, estaremos dando os primeiros passos na nossa jornada mitica. O que esperar dai? Nesta jornada encontramos as pessoas mais especiais, nos misturamos a elas, passamos a fazer parte de um sistema diferente, comprometido com a sustentabilidade e com o amor. Encontramos grandes mestres, cheios de conhecimento e historias, que nos elevam e inspiram a continuarmos nosso arduo movimento de convite, de contagio, a outros herois em seguir suas jornadas. Mas, principalmente, somos incentivados a encontrar com nossas sombras. Estes momentos transformadores, quando somos tentados a desviar do nosso caminho, em que o mais facil seria ceder a nossa raiva e medo, de agredir ao proximo, de marginalizar a diferenca, de reprimir a liberdade. Deparamo-nos nestes encontros com nossas sombras todos os dias, quando escolhemos nao educar a crianca pela palmada, quando nos esforcamos para nao agredir ninguem no transito, quando nos comprometemos a nao sermos corruptos, a nao encontrar jeitinhos para as situacoes desafiantes (as vezes nem tanto) de nossas vidas. Acredito que quando estamos caminhando pela luz, acompanhados por nossos mestres, podemos construir conhecimentos libertadores destas praticas violentas e corruptas. Remeto-me a minha jornada, quando conheci Harlene Anderson e os conhecimentos da terapia colaborativa e da postura dialogica (Anderson, 2009). Foi um momento de dificil escolha, me afastar de praticas de saber especializado, para me aproximar de seres humanos, como outro ser humano, com compaixao e esperanca. Em minha jornada, constantemente invoco a voz desta mestre para iluminar minhas escolhas. Estou comprometido com uma pratica de amor, que preza pelos relacionamentos humanos como locais de transformacao. Que acredita e confia no processo das pessoas, sem querer guiar o processo a partir dos meus significados, aberto para a jornada do outro, como um companheiro, alguem com quem se comprometer com as transformacoes necessarias para o desenvolvimento. Esta voz esta sempre comigo, em minha imaginacao, ela e muitas outras vozes, pessoas importantes e pensamentos constantes com quem dialogo para a construcao de minha identidade e posicionamentos. Sao os personagens internos de Telma Lenzi (2013), que sao tao companheiros de nossas jornadas quanto as pessoas com quem nos conectamos. Podemos identificar estas vozes, as principais, que nos acompanham no cotidiano, por exemplo, e facil perceber em mim uma voz de repressao, que me culpa pelas minhas falhas, uma voz que chamo de general, ela me seduz a agir de forma a controlar meu contexto, para que possa ter o melhor resultado em cada situacao. Esta e uma voz a se questionar, ela me coloca em um caminho complexo de fins justificando meios, individualista na crenca de que eu saberia qual o melhor fim a ser alcancado. Para dialogar com esta voz construi outro personagem interno: o mestre interior (como aquele anciao verde do filme?), uma voz que me coloca em um caminho de esperanca e amor, que acredita no desenvolvimento dos processos, que e fascinado por acompanhar estes processos, apreciando cada desenvolvimento, cada transformacao. Esta voz convida o general para o dialogo, entendendo seus medos e aceitando suas coerencias historicas. Com amor, eu dissolvo meus medos e me afirmo em um caminho mais social de transformacao com meus companheiros de jornada, sejam eles meus familiares, amigos, estudantes e clientes. Ha de confiar que cada um deles se desenvolvera da melhor forma, se eu estiver participando com minha colaboracao, curiosidade e fe em seus processos. Quando nos engajamos as nossas vozes internas, quando encontramos dialogo privado, desenvolvemos o conhecimento de nos mesmos, elevamos nossa percepcao de recursos pessoais, como em um estado meditativo, encontramos paz e sabedoria em nossas escolhas. No dialogo externo, com as pessoas que encontro em meu cotidiano, exploramos nossas historias, desenvolvemos o conhecimento de si, do outro e do mundo, de forma a empodera-las de suas autorias sobre suas historias e as contagiar de esperanca para novos movimentos, sempre norteados pela paz e compaixao por quem sera participante destas acoes. Esta e uma pratica politica, de buscar o seu desenvolvimento, enquanto facilita o desenvolvimento do seu universo. Lembro-me da historia da arvore, que se nutre atraves da fotossintese, ingerindo gas carbonico e expelindo precioso oxigenio, que se reproduz usando frutos, nutrindo, por sua vez, outros seres vivos. A arvore e um ser politico, ela busca seu desenvolvimento enquanto facilita o desenvolvimento da vida ao seu redor. Se, em nossas jornadas, pudermos ser tao bons quanto uma arvore, ja estaremos fazendo grande diferenca no nosso mundo. Se a vida inspira a arte, podemos acreditar que a arte inspira a vida em retorno. Este inicio de uma nova aventura da saga Star Wars inspira uma nova geracao a estarem atentos aos convites para suas aventuras, a se conectarem com seus companheiros de jornada, a encontrarem seus mestres disfarcados e se comprometerem ao desenvolvimento que eles facilitam para, entao, desenvolverem seu conhecimento e vozes internas que o acompanharao no dialogo interno para a construcao do enfrentamento de suas sombras e desafios, para se encontrarem com conceitos de compaixao, esperanca e liberdade, transbordando de luz e dissolvendo as sombras que nos tentam aos caminhos mais faceis e irresponsaveis de acao no mundo.

The search for the Standard Model Higgs boson in the four lepton (electron and muon) final state with the ATLAS detector at the LHC is presented. The analysis strategy and the efficiency for selecting the signal and rejecting the background are discussed, focusing on the performance of the lepton identification that can be achieved with the first data of LHC expected in 2008.

Sao apresentados os resultados de testes de um espectrometro de massa por tempo de voo contendo um espelho eletrostatico (“Reflectron”), que foi projetado e construido no Laboratorio de Instrumentacao e Particulas do Instituto de Fisica da USP. Medidas utilizando o sal iodeto de cesio (CsI) e o fulereno (C60) permitiram determinar as caracteristicas do equipamento.

Ballistocardiography (BCG) is a non-invasive technique that measures the recoil forces of the body in reaction to the cardiac contraction and blood flow through the vessels. This work compares the performance of a virtual reality (VR) headset-embedded gyroscope and of a novel high-performance gyroscope in measuring median HR from the BCG signal obtained from subtle head movements. Nine healthy volunteers were enrolled in this study. Head BCG signals were acquired for 1 minute in supine position using the triaxial gyroscope (VRG) embedded in an Oculus Quest (Facebook) headset, and a monoaxial high-performance gyroscope (HPG). 1-lead ECG signal was acquired simultaneously and used as a gold standard for HR measurement (HR<inf>ECG</inf>). Automatic beat-by-beat identification was performed on the BCG signals, from which median HR was computed (HR<inf>VRG</inf> and HR<inf>HPG</inf>). Results obtained with the three sensors were statistically compared, and linear regression and Bland Altman analyses were performed. Pitch and roll head rotations provided more accurate HR estimates compared to the yaw rotation, with more marked peaks in the BCG signal, possibly due to the to the anatomical orientation of the carotid arteries and to how the head is perfused with blood. Also, the HPG outperformed the VRG, thus potentially allowing a more detailed analysis of the BCG signal morphology, with possible application in the extraction of novel biomarkers with clinical utility.

Frequentemente, em nossas práticas clínicas, nos deparamos com clientes que buscam a terapia com temas relacionados às práticas sexuais, à sexualidade e/ou ao gênero. Desenvolvemos com estes clientes um diálogo sobre os significados que acompanham estes dilemas, explorando e enriquecendo onhecimentos, favorecendo a transformação das formas como nos relacionamos com o fenômeno e a coerência da problematização. Neste artigo, gostaríamos de convidar ao diálogo algumas vozes que participam da significação do encontro sexual, desde tradições antigas e rígidas, a inteligibilidades liberais, de entendimentos culturais, a experiências situadas. Então, propomos uma nova forma de entendimento do encontro sexual, que nomeamos sexo dialógico por suas características intrinsecamente associadas ao diálogo e às transformações que ele gera.DOI http://dx.doi.org/10.21452/2594-43632018v27n60a04

Motivados pelo sofrimento e transformacao de uma cliente ao longo do processo terapeutico, este artigo apresenta reflexoes resultantes de um estudo de caso socio construcionista acerca dos significados atribuidos as “dificuldades de aprendizagem” para uma estudante de 15 anos. A pesquisa utilizou como caminho metodologico relatos da estudante, entrevista se-mi-estruturada e reflexoes da autora/ terapeuta. Percebemos que ao longo das nossas conver-sacoes os significados atribuidos ao TDAH transformaram-se, pois ja nao tinham peso de “dificuldades”. Uma nova forma de relacionamento com o entorno educacional foi construida, uma que presa pela singularidade e responsabilidade relacional. DOI http://dx.doi.org/10.21452/2594-43632018v27n62a05

At each cardiac beat, blood flowing through the arterial tree produces micro-movements that can be measured by positioning inertial sensors in contact with the body. The resulting signal is the ballistocardiogram (BCG). The study aims to demonstrate the feasibility to exploit inertial sensors embedded in a virtual reality (VR) headset to estimate heart rate (HR). Eight volunteers were enrolled. 1-minute head BCG signals were acquired in supine, sitting and standing position using the tri-axial accelerometer and gyroscope (f <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</inf> =71[71;77] Hz) integrated in a Oculus Quest (Facebook) VR headset. Linear and rotational kinetic energies were computed and used to automatically detect cardiac beats. Inter-beat intervals were extracted and mean HR was computed. In addition, 1-lead ECG signal was acquired and used as a gold standard for HR measurement. The HR values computed from BCG in each posture were compared with the gold standard (Wilcoxon Signed Rank Test, p< 0.05). Correlation (r <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) and Bland Altman analyses were also performed. Best results were obtained using the rotational kinetic energy derived by the gyroscope, obtaining HRs comparable to the gold standard in both supine and sitting postures, with high correlation, no bias, and acceptable limits of agreement. In standing posture, the balancing movements for body equilibrium maintenance contributed reducing HR estimate accuracy. This is the first study in which HR has been measured using kinetic energy computed from the head-BCG obtained with a commercial VR headset, providing important insights on the possibility to expand the use of inertial units to accurately and non-invasively monitor physiological parameters.
