Modified Pectus Up and the Portuguese Case Series
Graça, Luís Lourenço; Canotilho, António; Pagaimo, Filipe; Morais, Gonçalo; Ferreira, Bárbara; Lopes, Rita; Lareiro, Susana; Pancas, RitaIntroduction: Pectus excavatum (PE) is the most common congenital chest wall deformity, with an incidence of 1 in 400 births. Surgical approaches vary depending on the severity of the condition. Recently, the taulinoplasty approach - "Pectus Up®" - was described as an alternative to lift the sternum through external traction, avoiding invading the mediastinum or pleural cavity. We describe our progressively mod...
Agreement Between a Wristwatch and a Free Optical Sensor with a Chest Strap in ...
Bartolomeu, Raúl Filipe; Silva, Vasco; Pereira, Ana; Morais, Gonçalo; Sokołowski, Kamil; Strzała, Marek; Morais, J.E.; Teixeira, José EduardoWearables with optical sensors for heart rate (HR) measurement are widely available in the market. However, their accuracy in water is still underexplored. The aim of the present study was to test the agreement of two different devices for HR monitoring with a chest strap while swimming at different intensities. Twenty male and ten female subjects (mean 19.6 ± 0.7 years old, 173.3 ± 5.4 cm, and 67.1 ± 6.6 kg) p...

A influência dos pais na iniciação e manutenção da prática desportiva de crianç...
Pereira, Ana; Morais, Gonçalo; Paixão, Vitor; Fonseca, Teresa; Fernandes, Hélder MiguelOs principais objetivos deste estudo são conhecer e comparar a influência parental na iniciação e manutenção da prática desportiva de diferentes desportos (atletismo, karaté, basquetebol, voleibol, futebol), de acordo com a perceção de treinadores de crianças e jovens. A recolha de dados foi realizada através de entrevistas semiestruturadas. Os participantes deste estudo foram cinco treinadores (um do sexo femi...
Bounded domains of negative multipliers
Johnson, Charles; Morais, GonçaloA natural problem associated with coupling of non-autonomous oscillators and synchronization is described. It leads to a question about the boundedness of a domain associated with a derived quadratic form. Properties of real symmetric matrices with bounded domains are developed, and unboundedness is translated into satisfiability of a certain Lyapunov-like matrix form. Eventually the real symmetric matrices ass...
Generalized synchronization in a system of several non-autonomous oscillators c...
Martins, Rogério; Morais, GonçaloAn abstract theory on general synchronization of a system of several oscillators coupled by a medium is given. By generalized synchronization we mean the existence of an invariant manifold that allows a reduction in dimension. The case of a concrete system modeling the dynamics of a chemical solution on two containers connected to a third container is studied from the basics to arbitrary perturbations. Conditio...
