Jets and charged hadrons in heavy-ion collisions with the ATLAS detector

Ultrarelativistic heavy-ion collisions at the LHC produce the quark–gluon plasma. Jets are a useful probe to study this state of matter since they are produced at the early stages of the collisions and are expected to be modified as propagating through the medium. One observable is the energy loss lowering the jet yields at a given transverse momentum. Other observables are the modification of the dijet momentum balance and the modification of fragmentation functions. A phenomenon strictly correlated to the jet energy loss is the modification of the charged-hadron momentum spectrum. The large new Pb+Pb data sample collected by ATLAS in Run 2 allows for precision measurements of these observables in a wide transverse momentum range and in different centrality and rapidity intervals.Peer Reviewe

Tissue and cell's trafficking: a byproduct of transplant activity's trash. The future is now. A Public Health problem

Transplantation is one of the most beautiful achievements for humanity in the last century and became the last hope to many patients. As other beautiful achievements, it has been used by criminals. The future of transplantation will be focused on tissue and cells transplantation. Trafficking of human beings to organ removal and trafficking of human organs are an early stage of trafficking on tissues and cells comparable with slaves trafficking in the 17th and 18th century. As 400 years ago, the motive for the crime is development, economy and profit. Transplant surgery is the modern “cotton gin” to this new commerce. Poverty exploitation, unprotected people, are always the victims. Even so, there are some differences since then. The paying buyers are the patients themselves and the “cotton” transplanted is not so harmless. Unsafe tissues and cells inappropriately collected and allocated can be so dangerous to the recipient and his family, that the dreamed transplant/implant becomes a nightmare. Beyond the trafficking crime, there is a most dangerous associated crime that is the crime of spreading dangerous infectious diseases

Planejamento e motivação: construindo aliados na prática docente

Trabalho apresentado no II Congresso Nacional do PROJETO RONDON, realizado em Florianópolis, SC, no período de 23 a 25 de setembro de 2015 - Universidade Federal de Santa Catarina.Este trabalho irá relatar oficinas desenvolvidas com os professores das redes municipal e estadual, no município de São Bento do Tocantins, durante a Operação Itacaiúnas do Projeto Rondon, em julho de 2015. Foi realizado um encontro na Câmara Municipal da cidade, com duas horas destinadas a cada oficina. A partir da demanda apresentada pela secretária de educação do município durante a viagem precursora relatando dificuldades dos professores em desenvolver planos de aula e em construir o Projeto Político Pedagógico, e, também queixas de desmotivação e cansaço frente à rotina escolar, idealizou-se a realização de um encontro para abordagem dos dois temas, a fim de que se pudesse estabelecer uma relação entre o planejamento e suas implicações no cotidiano escolar, trazendo a motivação desses profissionais como pano de fundo de toda a discussão. Iniciamos com a videoconferência “Planejamento como ação educativa”, com o objetivo de reconhecimento da importância do planejamento na prática docente. Trabalhou-se diferentes tipos de planos e suas caraterísticas, buscando evidenciar a importância disto na rotina escolar. A videoconferência foi realizada com a professora Ana Delacoste, da Faculdade de Educação da PUCRS. Uma das solicitações da professora foi a interação com os participantes, tornando esse momento mais significativo devido à troca de experiências e às relações estabelecidas entre teoria e prática no decorrer da oficina. Como multiplicadores, os rondonistas devem levar para os municípios em que atuam novos meios de conhecimento e acesso à informação. Apesar das dificuldades relacionadas à conexão via internet, esse momento atendeu às expectativas dos participantes, esclarecendo dúvidas, promovendo uma reflexão em torno do tema, além de apresentar uma nova forma de interação e formação continuada. A segunda oficina, “Motivação para educar”, objetivava proporcionar um espaço para que os professores refletissem a respeito dos desafios enfrentados no cotidiano escolar e o quanto isso reverbera em sua motivação durante o trabalho. Por meio de dinâmicas de integração e vídeos de sensibilização, construiu-se um espaço onde todos puderam compartilhar suas experiências e conscientizar-se da importância desse profissional na comunidade em que vive. As duas oficinas foram complementares pois proporcionaram um espaço de reflexão acerca dos desafios vivenciados pelos docentes. E, mais do que reflexões, foi possível presenciar um empoderamento desses profissionais que hoje, têm maior ciência de sua importância na comunidade escolar e almejem uma melhora em suas práticas através de uma formação continuada e significativa

The impact of structural capital on the firm Innovativeness, the Galician Northern Portugal automotive industries reality

The intellectual capital is increasingly considered a major issue on the management and organization research and a source of competitive advantage. Although there are different models and approaches that try to identify the effect of intellectual capital on firm performance, there’s, also a lack of evidence and consensus. Based on that evidence, this paper focuses on the influence of the structural capital on the product- process and management innovativeness of the firm. A global model including the variables used in the previous literature is used and we establishes hypotheses for testing this model and use statistic technique to estimate the parameters of the model in a sample. To do so, we use a survey from 68 firms working on the auto components sector, established in the Northern Spain and Northern Portugal. We found firstly, that innovativeness has two main dimensions, perfectly differentiated, the product-process innovation and the management innovation; secondly that the structural capital dimensions influences differently each type of innovation capacity (innovativeness). We also concluded that the structural capital of the automotive firms based on the euro region Galicia (Spain) Northern Portugal influences positive and directly the management innovativeness. These results highlight the importance of the structural capital as well as highlight the main dimensions that influence the innovativeness, and more broadly, the value of intellectual capital as a competitive advantage in contemporary time. Moreover, point out the different character of product-process and management innovativeness.

Dar a ver o indizível: as capulanas no norte de Moçambique

Este texto reflete teoricamente sobre as capulanas na região norte de Moçambique, e é baseado em trabalho de campo realizado nas cidades de Nampula e Ilha de Moçambique em 2015 e 2017. A partir de um diálogo com as proposições teóricas de Alfred Gell e Bruno Latour, proponho pensar como fazer capulanas não se restringe à produção, mas passa, principalmente, pela circulação e suas múltiplas formas de uso. Reflito, também, no que as capulanas fazem-fazer, e, sobretudo, no que fazem não-fazer. Ao cobrir os corpos e transmitir mensagens acerca de temas sensíveis como a doença, a morte ou a menstruação, elas permitem manter a esfera do invisível e do indizível, e, assim, “guardam segredo”Este texto trae una reflexión teórica basada en las propuestas de Alfred Gell y Bruno Latour para trabajar el material etnográfico de una investigación sobre capulanas (tejidos estampados) en la región norte de Mozambique. Se trata de establecer un vocabulario teórico que nos permita pensar en las relaciones entre mujeres y sus tecidos, y, al mismo tiempo, ver en qué nos permiten pensar las capulanas – los límites y posibilidades – cuando contrastadas con las proposiciones de los autores. Propongo, entonces, pensar en cómo "hacer capulanas" no se restringe a la producción, sino que pasa, principalmente, por la circulación y sus múltiples formas de uso. También reflexiono sobre lo que "hacen-hacer" las capulanas, pero sobre todo lo que "hacen no hacer", manteniendo la esfera de lo invisible y lo indecible.This article presents a theoretical reflection on capulanas (wax print fabrics) in the northern region of Mozambique. It is based on fieldwork conducted in Nampula and Ilha de Moçambique in 2015 and 2017. Beginning with a dialogue with the theoretical propositions of Alfred Gell and Bruno Latour, it suggests that “making capulanas” is not restricted to production. Instead, it happens mainly through circulation and its multiple forms of use. In addition, it addresses what capulanas are “made to do” (faire-faire) and especially what they “make not do” (faire ne pas faire). By covering the bodies and transmitting messages about sensitive matters such as illness, death, and menstruation, they harbor the spheres of the invisible and the unspeakable, and thus they “keep secrets.

A Patch-Wise Generative Adversarial Network for PET-MR Image Generation with Feature Attribution for Detection of Focal Cortical Dysplasia

Tese de mestrado integrado, Engenharia Biomédica e Biofísica (Engenharia Clínica e Instrumentação Médica) Universidade de Lisboa, Faculdade de Ciências, 2022More than 50 million people worldwide suffer from epilepsy with a third of those being diagnosed with drug-resistant epilepsy where the seizures cannot be treated through pharmacotherapy. In these cases, surgical removal of the epileptic brain tissue in patients is presented as an effective solution for treatment. However, for surgery success, it is vital that the accurate location of epileptic regions in the brain are known. Neuroimaging, specifically magnetic resonance imaging (MRI) and positron emission tomography (PET), commonly are the doctor’s allies in identifying these lesions’ locations responsible for the seizures. Focal cortical dysplasias (FCDs) are the most common type of cortical lesions respon sible for drug-resistant epilepsy in children. These lesions have highly heterogeneous masses, occur in different brain regions and result in different levels of visibility, corresponding to the second most in tractable type of lesion in adults with epilepsy. Moreover, among drug-resistant epilepsy cases, a third of these lesions cannot be correctly identified by neuroimaging experts, resulting in unsuccessful surgical planning and consequently ineffective treatment for patients. Recently, Generative Adversarial Networks (GANs) have demonstrated their value in neuroimaging anomaly detection. Therefore, this work pro poses the application of two different GAN methods – WGAN and CycleGAN - for anomaly detection of FCDs, in PET-MRI data of epileptic patients. A 3D patch-basis anomaly detection approach was therefore developed, inspired by previous works, to detect FCDs location by deconfounding acquisition noise and normal cortical variabilities in PET-MR brain scans of epilepsy patients. Therefore, the GAN models applied two different approaches for lesion detection: detection through reconstruction (WGAN) and detection through translation (CycleGAN). Moreover, the combination of PET and MR modalities was studied and compared to training the networks with individual imaging modalities instead. Through the results, it was possible to understand and correct some issues GAN models have when training with multimodal 3D data. However, both methods for anomaly detection were able to detect diseased brain areas in patients with very visible FCDs, although failing to identify them in patients with very subtle lesions. Recent studies will be briefly discussed in the conclusion, which propose new approaches and architectures for multimodality training, with great potential to improve the performance of the networks for anomaly detection in future works
