Cutaneous Metastasis in Advanced Gastric Cancer.

Prospective Study of Pulmonary Sequelae in Hospitalized COVID-19 Patients durin...

Introduction: Current evidence seems to suggest the persistence of long-term multisystemic sequelae in COVID-19 survivors. The evolution of symptoms after the acute phase is still uncertain, as is their real impact. Methods: This prospective observational study began during the first phase of the pandemic in Portugal and sought to follow patients hospitalized with COVID-19 for two years after discharge, analyzi...

Creative duet. : Speculating architecture through art and computing

This article seeks to argue about the contributions of the area of ​​knowledge and production of Computational Art for the development of Architecture. Among the possible contributions, this text emphasizes the duet structure and the contingent quality present in part of the production of Computational Art with a focus on interactivity. As a methodology, a literature review was developed and to corroborate the ...

Housekeeping System for Suborbital Vehicles: VIRIATO Mock-Up Vehicle Integratio...

The work presented in this paper regards the improvement of a housekeeping system for data acquisition of a suborbital vehicle (VIRIATO rocket or launcher). The specifications regarding the vehicle are presented and hardware is chosen accordingly, considering commercial off-the-shelf components. Mechanical and thermal simulations are performed regarding the designed system and a physical prototype is manufactur...

Flapping Airfoil Aerodynamics using Recurrent Neural Network

The recent increase in interest in artificial intelligence and neural networks has stirred up various industries. Inevitably, its application will trickle down to the most fundamental studies, for instance, unsteady aerodynamics. The present paper serves the purpose of exploring the ability of a recurrent neural network to predict flapping airfoil aerodynamics, in particular the lift coefficient of a plunging N...

The impact of revolutionary aircraft designs on global aviation emissions

The discussion about the environmental impact caused by aviation has gained greater prominence due to the increased demand for this sector and, consequently, the increase in the number of flights. Environmental concerns have stimulated the development of novel approaches to reduce pollutants and CO2 emissions. This study aims to assess the impact of disruptive concepts on commercial aircraft by reducing CO2 emi...

CHECKLIST DE RELAÇÕES INTERPESSOAIS-II: TESTE DA ESTRUTURA INTERNA

O Checklist de Relações Interpessoais-II (CLOIT-II) consiste em uma ferramenta que investiga os padrões de comportamento interpessoal em díades relacionais. O objetivo do estudo foi verificar se o CLOIT-II se ajusta ao modelo circumplexo no contexto laboral. Participaram 363 trabalhadores, respondendo ao CLOIT-II. A estrutura interna do instrumento foi avaliada por meio do Escalonamento Multidimensional Confirm...

Dynamics of a gyrostat satellite with the vector of gyrostatic moment tangent t...

In this paper, a gyrostat satellite in a circular orbit with its gyrostatic moment tangent to the orbital plane and collinear with the orbital speed is studied regarding its equilibria, bifurcation of equilibria, and asymptotic stability conditions. In the general case, where any gyrostat angular momentum is aligned with any of the orbital coordinate frames, interesting results arose regarding its equilibria bi...
