Hypersensitivity pneumonitis: Main features characterization in a Portuguese co...
Santos, V.; Martins, N.; Sousa, C.; Jacob, M.; Padrão, E.; Melo, N.; Mota, P. Caetano; Bastos, H.N.; Guimarães, S.; Moura, C. Souto; Sokhatska, O.Hypersensitivity pneumonitis (HP) is an interstitial lung disease (ILD) which varies in prevalence across the world, depending on disease definition, diagnostic methods, exposure type and intensity, geographical environments, agricultural and industrial practices, and host risk factors. This study aimed to deepen knowledge about HP's clinical characteristics, diagnosis and functional and imaging features in a c...
Gossip average consensus in a Byzantine environment using stochastic Set-Valued...
Silvestre, Daniel; Rosa, P.; Cunha, R.; Hespanha, J.P.; Silvestre, C.We address the problem of a consensus system in the presence of Byzantine faults seen as an attacker injecting a perturbation in the state of the nodes. We propose the use of Set-Valued Observers to detect if the state observations are compatible with the system dynamics. The method is extended to the stochastic case by introducing a strategy to construct a set that is guaranteed to contain all possible states ...
Prospective scenarios for water quality and ecological status in Lake Sete Cida...
Martins, Gilberto; Ribeiro, Daniel; Pacheco, Dina; Cruz, J. Virgílio; Cunha, R.; Gonçalves, V.; Nogueira, R.; Brito, A. G.The design of alternative strategies for water and ecological quality protection at the Lake Verde of Sete Cidades should be coupled with the assessment of future trophic states. Therefore, a mathematical model was developed to make prospective scenarios to reduce the risk of environmental degradation of the lake, and a modified Psenner scheme was used to characterize P distribution in the sediments. The model ...

Sousa, Manuel; Martins, Jorge; Cunha, R.Com a progressiva integração de serviços de voz, vídeo e dados, em novos sistemas de comunicação, resultantes da convergência tecnológica das tradicionais redes locais de computador e das redes públicas de telecomunicações, tem sido possível satisfazer os requisitos específicos das aplicações telemáticas, recorrendo a capacidades e protocolos de transmissão e de comutação adequados aos diferentes níveis de qual...
Waste management at Azores islands: challenges and opportunities
Brito, A. G.; Nogueira, R.; Cunha, R.An overview of the solid waste management practices in Azores is provided along with the guidelines and the waste projects comprised in the new Strategic Plan for Waste Management of Azores (PEGRA), under discussion. The Plan focus on waste valorisation, efficient use of resourses and protection of human health and ecosystems, under six thematic areas: i) ecoefficiency and consumption; ii) waste infrastructures...
Heterodimeric adenosine receptors: a device to regulate neurotransmitter release
Ciruela, F.; Ferré, S.; Casadó, V.; Cortés, A.; Cunha, R.; Lluis, C.; Franco, R.Abstract. Since 1990 it has been known that dimers are the basic functional form of nearly all G-protein-coupled receptors (GPCRs) and that homo- and heterodimerization may play a key role in correct receptor maturation and trafficking to the plasma membrane. Nevertheless, homo- and heterodimerization of GPCR has become a matter of debate especially in the search for the precise physiological meaning of this ph...
