description: A 19 years-old woman, on her 17th week of pregnancy presented to the emergency department with thoracic pain and vomiting. An empyema was diagnosed and she was transferred to a tertiary hospital for treatment. After drainage of the empyema a mediastinal mass was detected and a thoracic MRI revealed a multicystic lesion of the anterior mediastinum, causing cardiac and left lung compression, suggestive of a complicated teratoma. After a multidisciplinary discussion involving pulmonology, radiology, obstetrics and thoracic surgery, she was operated successfully by clamshell incision. A mature complicated teratoma was resected and a left pleurectomy/decortication performed. She was discharged on day 17 with no obstetrical or respiratory symptoms.

description: Exercise echocardiography is used mainly in the study of patients with coronary artery disease, however the technique is increasingly used in the study of other pathologies. We present the first case of use of exercise stress echocardiography for clinical decision in one patient with biological prostheses in tricuspid position. The clinical exam, the echocardiogram, the cardiac MRI, the NT proBNP were normal and the patient has been considered to have no indication for surgery. The patient was only presented and accepted for surgery after the results of exercise stress echocardiography.

description: Objectives: Pneumonectomy is a procedure with high post-operative morbidity and mortality. This study aims to assess and identify possible risk factors that can affect post-operative outcome, therefore determining the safety of pneumonectomy in specific groups. Methods: A total of 63 patients submitted to pneumonectomy at our centre, from February 2008 to February 2018, were included in our retrospective study. Age, gender, side of intervention, diagnosis, pre-operative symptoms, substance abuse and comorbidities were assessed. Early and late post-operative complications, as well as death were our major outcomes. We analysed the impact of preoperative variables on major outcomes using SPSS statistics. Results: We found a 9,8% surgery-related mortality and 1-year survival rate of 76,2%. The incidence of early complications in our population was of 35% while eleven patients (17,4%) developed late post-operative complications. No statistical difference was found when comparing survival time between genders or age groups. Right sided pneumonectomies seem to be associated with an higher mortality risk. No other association between risk factors and outcomes reached statistical significance in both univariate and multivariate analysis. Conclusions: Pneumonectomy is a viable option regardless of age whenever the patient has a good functional and cardiopulmonary status. Gender and diagnostic group do not seem to influence adverse event risk, although right- -sided pneumonectomies show an increased risk for post-operative death. Care should be taken with patients submitted to neoadjuvant therapy. All patients should be encouraged to cease smoking as early as possible before surgery, given the increased risks for post-operative complications.

description: We present a model for the decay D+ --> K- pi+ pi+. The weak interaction part of this reaction is described using the effective weak Hamiltonian in the factorisation approach. Hadronic final state interactions are taken into account through the Kpi scalar and vector form factors fulfilling analyticity, unitarity and chiral symmetry constraints. The model has only two free parameters that are fixed from experimental branching ratios. We show that the modulus and phase of the S wave thus obtained agree nicely with experiment up to 1.55 GeV. We perform Monte Carlo simulations to compare the predicted Dalitz plot with experimental analyses. Allowing for a global phase difference between the S and P waves of -65 degrees, the Dalitz plot of the D+ --> K- pi+ pi+ decay, the Kpi invariant mass spectra and the total branching ratio due to S-wave interactions are well reproduced.

Le mythe du Graal chez Julien Gracq, romancier
Creators: name: Furney, Paulette Jacqueline
Publisher: name: University of British Columbia
Year: 2011

description: Julien Gracq, de son vrai nom Louis Poirier, né en 1909 dans le Maine-et-Loire, agrégé d'histoire et professeur dans un lycee parisien, est un ecrivain dont l'oeuvre s'est eche-lonnle depuis 1938 jusqu'a, nos jours. II a publié jusqu'a pré quatre romans: Au Chateau d'Argol (1938), Un Beau Ténébreux (1945), Le Ravage des Syrtes (1951—Prix Goncourt qu'il a d'ailleurs refuse) et Un Balcon en Foret (1958), et une seule piéce de theatre, Le Roi-Plcheur (1948), en dehors de quelques poémes en prose, essais et textes critiques. II est à noter que son unique piéce de théatre est inspi-ree du mythe du Graal. Dans 1'Avant-Propos a. cette piece, il expose les raisons qui l'ont poussé à faire ce choix. II porte un intéret persistant au mythe en général, et en particulier aux mythes médiévaux, dans lesquels il voit des mythes "ouverts", par opposition avec les mythes "fermés" que sont, d'après lui, les mythes grecs. Nous avons remarqué également que le premier roman, Au Chateau d'Argol, est—c'est Gracq lui-meme qui nous le dit—une "version démoniaque" du mythe du Graal, et que les allusions à ce mythe foisonnent dans les trois autres romans. II nous a done paru interessant de rechercher a travers les quatre romans—ou récits—les transpositions apportees au mythe initial, retracant en particulier les modifications qu'ont subissles themes du voyage, du chateau perilleux, de la communaute élective, de l'attente et enfin de la tentation, thèmes préexistant dans le my the médiéval. Au cours de ce travail, nous avons été amenés à étudier la possibility d'une evolution méthodique du mythe parallele a l'évolution du héros, possibilité que nous avons rejetee. Au lieu d'accepter l'idée d'une évolution du mythe a travers l'oeuvre, nous pensons qu'il s'agit plutot de l'étude d'une série de tentatives diverses, ou meme de différentes étapes de la quite. Nous avons aussi repondu a l'objection formulée par J. Baudry, concernant l'absence de Galaad dans ces romans, de laquelle il déduisait le caractere "fermé" du mythe tel que transposé par Gracq, et non plus "ouvert". Là encore, nous sommes arrives a une conclusion differente, c'est-a-dire que l'absence de Galaad de ces oeuvres n'engageait pas le futur et qu'il était toujours possible à Julien Gracq d'apporter au mythe une "fin", en faisant arriver le chevalier érant du Graal dans un roman ultérieur.

description: Since the set of volumes of hyperbolic 3-manifolds is well ordered, for each fixed g there is a genus-g surface bundle over the circle of minimal volume. Here, we introduce an explicit family of genus-g bundles which we conjecture are the unique such manifolds of minimal volume. Conditional on a very plausible assumption, we prove that this is indeed the case when g is large. The proof combines a soft geometric limit argument with a detailed Neumann-Zagier asymptotic formula for the volumes of Dehn fillings. Our examples are all Dehn fillings on the sibling of the Whitehead manifold, and we also analyze the dilatations of all closed surface bundles obtained in this way, identifying those with minimal dilatation. This gives new families of pseudo-Anosovs with low dilatation, including a genus 7 example which minimizes dilatation among all those with orientable invariant foliations.

description: Objectives: Jatene surgery or arterial switch is performed at our institution since the late nineties. We reviewed our results to identify the main causes of reoperation and, more importantly, to determine what variables predict the need for reoperation. Methods: In this retrospective analysis were included all the 91 patients with d-TGA who underwent an arterial switch operation at our institution between 1995 and 2016. Results: Mean follow-up was 10 years (range 5-25 years). Seventy-one percent of patients had simple TGA and 29% had complex TGA. The need of reoperation was 21% (n=19 patients). Right ventricle outflow tract obstruction was the main indication for reoperation (58%). The overall mortality was 9.9%. The gender (P= 0.8), diagnosis (simple or complex TGA) (P= 0,5) or the existence of palliative surgeries (P=0.9) were unable to predict the need for reoperation. The presence of anomalous coronary pattern was the only variable reaching statistical significance (P< 0.05), both in univariate and multivariate analysis. Conclusions: In our series, the main indication for reoperation after arterial switch operation was right ventricle outflow tract obstruction and the only predictive variable was the presence of anomalous coronary pattern.

description: We consider a generalized coagulation-decoagulation system on a one-dimensional discrete lattice with reflecting boundaries. It is known that a Bernoulli shock measure with two shock fronts might have a simple random-walk dynamics, provided that some constraints on the microscopic reaction rates of this system are fulfilled. Under these constraints the steady-state of the system can be written as a linear superposition of such shock measures. We show that the coefficients of this expansion can be calculated using the finite-dimensional representation of the quadratic algebra of the system obtained from a matrix-product approach.

description: Introduction: Aortic valve stenosis (AS) is the most common valvular pathology in the elderly and surgery (AVR) remains the gold-standard. However, transcatheter aortic valve replacement (TAVI) has become an emerging alternative to surgery. In a recent survey from the European Society of Cardiology, 9,4% stated that age was the main reason to propose for TAVI. Methods: Single-center retrospective study including 353 patients (149 ≥80 years-old;204 with 60-69 years-old) submitted to AVR between 2013-2016. Primary endpoint was survival. Secondary outcomes included the rate of post- -operative complications. Long-term survival was determined by Kaplan-Meier survival analysis. Continuous variables were analyzed with t-test and linear regression and categorical variables with chi-square or Fisher. Results: clinical characteristics were similar between the two groups. Both had similar survival at 30 days, 12 (93,29% 60-69yo vs 91,47% ≥80yo) and 24 months (88,34% 60-69yo vs 86,11% ≥80yo). However, rapid deployment valves (RD) had better survival rates in elderly patients. Cross-clamp time was lower in ≥80yo group, with higher percentage of RD valves (20,1% vs 4.9% in 60-69yo). The rate of post-operative atrial fibrillation was higher in >80yo group (29,06% vs. 17,28%,p=0,0147). In all patients, cross-clamp time was directly related to ventilation time(p=0,025) and chest drainage(p=0,0015). Conclusion: AVR after 80yo is safe. Cross-clamp time is directly correlated with ventilation time and bleeding, with a stronger correlation in patients over 80yo. RD valves reduce cross-clamp times, so their use in elderly may improve surgery outcome. Prospective studies are needed to evaluate if age may be clinical criteria for a RD.

description: The homotopy theory of infinity-operads is defined by extending Joyal's homotopy theory of infinity-categories to the category of dendroidal sets. We prove that the category of dendroidal sets is endowed with a model category structure whose fibrant objects are the infinity-operads (i.e. dendroidal inner Kan complexes). This extends the theory of infinity-categories in the sense that the Joyal model category structure on simplicial sets whose fibrant objects are the infinity-categories is recovered from the model category structure on dendroidal sets by simply slicing over the point.
description: This is essentially the published version, except that we added an erratum at the end of the paper concerning the behaviour of cofibrations with respect to the tensor product of dendroidal sets

description: Objectives: To compare 7-year survival and freedom from reoperation, as well as early clinical and hemodynamic outcomes, after surgical aortic valve replacement (SAVR) with mechanical or bioprosthetic valves in patients aged 50-70 years. Methods: single-center retrospective cohort study including adults aged 50-70 years who underwent SAVR in 2012 with a mechanical or bioprosthetic valve. Median follow-up was 7 years. Univariable analyses were performed using Kaplan- -Meier curves and Log-Rank tests for survival and freedom from reoperation analyses. Multivariable time-to-event analyses were conducted using Cox Regression. Results: Of a total of 193 patients, 76 (39.4%) received mechanical valves and 117 (60.6%) received bioprosthetic valves. A trend for better survival was found for mechanical prostheses when adjusting for EuroSCORE II (HR: 0.35; 95%CI: 0.12-1.02, p=0.054), but using a backward stepwise Cox regression prosthesis type was not retained by the model as an independent predictor of survival. Moreover, mechanical prostheses showed trends for higher freedom from reoperation (100% vs. 95.5%, Log-Rank, p=0.076), higher median EuroSCORE II (2.52% vs. 1.95%, p=0.06) and early mortality (7.9% vs. 2.6%, p=0.086). However, after adjusting for EuroSCORE II, there was no significant difference in early mortality (OR: 2.3, 95%CI: 0.5-10.5, p=0.272). Regarding hemodynamic performance at follow-up echocardiogram, there were no differences other than left ventricular mass regression, which was not as pronounced in the mechanical group (-12% vs. -21%, p=0.002). Conclusion: Mechanical and bioprosthetic aortic valves prostheses showed similar mid-term survival in the 50-70 age group. Further prospective and larger studies are needed to provide evidence-based recommendations on this topic.

WHY AND WHEN TO REQUEST FOR A PET/CT SCAN IN A LUNG CANCER PATIENT?
Creators: name: Colarinha, Paula
Publisher: name: Portuguese Journal of Cardiac Thoracic and Vascular Surgery
Year: 2021

description: This review will focus on whole-body functional imaging applied to lung cancer disease and patient management. Lung cancer needs to be avoided… (but if not well succeeded), suspected, screened, histologically confirmed, anatomically inventoried, prognostically staged, molecularly characterized, genetically studied and finally, therapeutically managed. Functional imaging using 18F-fluoro-deoxy-glucose (FDG) is a non-invasive method that is widely used in oncologic disease, mainly for clinical staging and re-staging, with impact on therapy planning. For lung cancer, the functional imaging with FDG-PET/CT is used for clinical staging and also to provide information on a pre-diagnostic phase, to categorize lung nodules according to the metabolic risk of malignancy. Clinicians need to be aware of the different possibilities of the functional imaging information, to provide the better use of it. This review will focus on data from the different medical fields that are considered important to informed decision making when asking for functional imaging in the daily clinical routine of a lung cancer patient.

A scent of flowers : a record and analysis of a production
Creators: name: Freiman, Judith Ann
Publisher: name: University of British Columbia
Year: 2011

description: A Scent of Flowers by James Saunders was produced and directed by Judith Freiman, in partial fulfilment of the requirements for a Master of Arts degree in the Department of Theatre of the University of British Columbia, at the Frederic Wood Studio Theatre from Wednesday, January 31 to Saturday, February 3, 1968. The following is a detailed record of that production along with the director's analysis and interpretation of the script. A Scent of Flowers was produced on a budget of $300.00 with a three and a half week rehearsal period and had a run of five performances in a theatre seating one hundred three people. The cast was composed of five students and three non-Equity performers. The set was designed by Brian Arnott; costumes, by Susan Gibson. This record is divided into three main sections. The first is an essay which begins with brief biographical information about James Saunders and a short discussion of his recurring basic themes and his style. This is followed by a detailed examination of A Scent of Flowers with particular emphasis on the structure of the play as the basis of the directorial concept. The essay concludes with re-emphasis on the play as an image. The second section is made up of the actual script including inserts and cuts, blocking, significant division into beats, and indicating light, sound, and scenery cues. For each major unit or beat there is a brief analysis which indicates the directorial approach taken in terms of purpose, action, dominant emotions, character dominance, and any difficulties involved. The third section is made up of various tables, records, and illustrations relating directly to the production. Included are the insertions for the mass in Act II and lists of light cues, music cues, properties, costumes, cost lists, and box office reports. Also included are a sample of the program and copies of the press reviews. The illustrations include colour photographs of the production, costume drawings, and finally, blueprints of the floor plan and working drawings.

description: Background: An asymptomatic carotid stenosis (CS) is defined as a stable atherosclerotic luminal narrowing in patients with no history of ipsilateral cerebral or ocular ischemic events in the past six months. The bifurcation of the common carotid artery makes this area vulnerable to atherosclerosis due to the features of haemodynamic flow. The exact prevalence of asymptomatic patients with CS remains unknown and opinions on the treatment of these patients are controversial. Objective: The authors aimed to review the evidence on the management of the asymptomatic CS and describe its clinical characteristics, diagnosis and treatment management. Methods: A comprehensive review of the literature was carried out to collate data from relevant studies concerning patients with extracranial moderate to severe asymptomatic carotid stenosis. The data used was identified by a search using PubMed and Google Scholar with the keywords / MESH terms "carotid stenosis", in combination with the term "asymptomatic". For this study, the authors focused on publications in the past two decades, using English publications. Results: A few studies have addressed the prevalence, natural course and/or prognostic impact of asymptomatic CS in patients under medical treatment or undergoing vascular surgery procedures. The prevalence of asymptomatic CS ranged from 0.3% to 4.5% in women and 0.5% to 5.7% in men - The risk of stroke/TIA in these patients was reported between 2% to 5% annually with a downward trend across time to 0.5% with current best medical therapy. Conclusion: A great proportion of patients with asymptomatic CS should be submitted to conservative management with best medical therapy. However, selective surgical management should be considered if high risk features are present.

description: The tetrameric Ni(II) spin cluster Ni4Mo12 has been studied by INS. The data were analyzed extensively in terms of a very general spin Hamiltonian, which includes antiferromagnetic Heisenberg interactions, biquadratic 2-spin and 3-spin interactions, a single-ion magnetic anisotropy, and Dzyaloshinsky-Moriya interactions. Some of the experimentally observed features in the INS spectra could be reproduced, however, one feature at 1.65 meV resisted all efforts. This supports the conclusion that the spin Hamiltonian approach is not adequate to describe the magnetism in Ni4Mo12. The isotropic terms in the spin Hamiltonian can be obtained in a strong-coupling expansion of the Hubbard model at half-filling. Therefore detailed theoretical studies of the Hubbard model were undertaken, using analytical as well as numerical techniques. We carefully analyzed its abilities and restrictions in applications to molecular spin clusters. As a main result it was found that the Hubbard model is also unable to appropriately explain the magnetism in Ni4Mo12. Extensions of the model are also discussed.

description: We present MMT/Megacam imaging of the Leo~IV dwarf galaxy in order to investigate its structure and star formation history, and to search for signs of association with the recently discovered Leo~V satellite. Based on parameterized fits, we find that Leo~IV is round, with $ε< 0.23$ (at the 68\% confidence limit) and a half-light radius of $r_{h} \simeq 130$ pc. Additionally, we perform a thorough search for extended structures in the plane of the sky and along the line of sight. We derive our surface brightness detection limit by implanting fake structures into our catalog with stellar populations identical to that of Leo~IV. We show that we are sensitive to stream-like structures with surface brightness $μ_{r}\lesssim29.6$ mag arcsec$^{-2}$, and at this limit, we find no stellar bridge between Leo IV (out to a radius of $\sim$0.5 kpc) and the recently discovered, nearby satellite Leo V. Using the color magnitude fitting package StarFISH, we determine that Leo~IV is consistent with a single age ($\sim$14 Gyr), single metallicity ($[Fe/H]\sim-2.3$) stellar population, although we can not rule out a significant spread in these value. We derive a luminosity of $M_{V}=-5.5\pm0.3$. Studying both the spatial distribution and frequency of Leo~IV's 'blue plume' stars reveals evidence for a young ($\sim$2 Gyr) stellar population which makes up $\sim$2\% of its stellar mass. This sprinkling of star formation, only detectable in this deep study, highlights the need for further imaging of the new Milky Way satellites along with theoretical work on the expected, detailed properties of these possible 'reionization fossils'.

Subjects: subject: Habilidades de pensamiento crítico
subject: Método en el contexto del aprendizaje de lenguas extranjeras

description: This experience allowed me to apply and consolidate my critical thinking skills and propose solutions to problems in different contexts. I used a combination of theoretical knowledge acquired during my academic process in the Foreign Languages program and practical aspects of professional reality learned through my teaching practicum. I contributed to improving the educational process at the school where I carried out my practicums, strengthening its educational project. In addition, I had the opportunity to demonstrate that I am a professional capable of proposing and using scientific research as a tool that enables the improvement of sociocultural processes, especially those in the field of education. Another important point to highlight is that, through this experience, due to the need to be aware of the particularities and advantages of the Montessori method and the lack of available information about its applicability to the teaching of foreign languages, I had the opportunity to learn about different approaches, theories, and methodologies in the field of education. This allowed me to have a broader and more diverse perspective on education. Through reflective practice, I concluded that the most significant impact of this educational experience on me was its promotion of my professional and personal growth. This led me to become an educational actor capable of developing comprehensive teaching processes that are human-centered and responsive to the needs of my students. These processes offer meaningful learning that stimulates motivation and interest, and that encourages students to play an active role in their education and to take ownership of it. This, in turn, allows students to recognize themselves as members of society and to reflect on how they can contribute to it from their role.

Covariance Intersection in Nonlinear Estimation Based on Pseudo Gaussian Densities
Creators: name: Noack, Benjamin

Publisher: name: Karlsruhe
Year: 2011

description: Many modern fusion architectures are designed to process and fuse data in networked systems. Alongside the advantages, such as scalability and robustness, distributed fusion techniques particularly have to tackle the problem of dependencies between locally processed data. In linear estimation problems, uncertain quantities with unknown cross-correlations can be fused by means of the covariance intersection algorithm, which avoids overconfident fusion results. However, for nonlinear system dynamics and sensor models perturbed by arbitrary noise, it is not only a problem to characterize and parameterize dependencies between estimates, but also to find a proper notion of consistency. This paper addresses these issues by transforming the state estimates to a different state space, where the corresponding densities are Gaussian and only linear dependencies between estimates, i.e., correlations, can arise. These pseudo Gaussian densities then allow the notion of covariance consistency to be used in distributed nonlinear state estimation.

description: The Practicum is a practical experience that is an essential requirement to forge our formation as future university professionals in the field of teaching. Over the course of eight months, students are immersed in the reality of being foreign language teachers, having the opportunity to assume crucial responsibilities such as lesson planning and the creation of teaching materials. This exercise not only provides them with a space to apply the knowledge acquired in their theoretical training, but also allows them to improve practical pedagogical skills. During this process, students have the flexibility to choose the educational organization of their choice. This practicum took place in the educational institution Madre Laura, located in the city of Cartagena in Piedra Bolívar neighborhood near to the University of Cartagena. This organization is legally recognized by the Secretariat of District Education of Cartagena de Indias, by Resolution No. 0176 of April 18, 2012, to teach Formal Education in the locations Madre Laura, José María del Castillo y Rada Andalucía, at the levels of Preschool, Basic Primary and Basic Secondary.

description: When a system undergoes a quantum phase transition, the ground-state wave-function shows a change of nature, which can be monitored using the fidelity concept. We introduce two Quantum Monte Carlo schemes that allow the computation of fidelity and its susceptibility for large interacting many-body systems. These methods are illustrated on a two-dimensional Heisenberg model, where fidelity estimators show marked behaviours at two successive quantum phase transitions. We also develop a scaling theory which relates the divergence of the fidelity susceptibility to the critical exponent of the correlation length. A good agreement is found with the numerical results.
