STM-GNN: Space-Time-and-Memory Graph Neural Networks for Predicting Multi-Drug ...
Geissbuhler, Damien; Bornet, Alban; Marques, Catarina; Anjos, André; Pereira, Sónia; Teodoro, DouglasHospital-acquired infections (HAIs), particularly those caused by multidrug-resistant (MDR) bacteria, pose significant risks to vulnerable patients. Accurate predictive models are important for assessing infection dynamics and informing infection prediction and control (IPC) programmes. Graph-based methods, including graph neural networks (GNNs), offer a powerful approach to model complex relationships between ...
Outdoor airborne allergens: Characterization, behavior and monitoring in Europe
Grewling, Lukasz; Ribeiro, Helena; Antunes, Célia; Apangu, Godfrey; Çelenk, Sevcan; Costa, Ana; Eguiluz-Garcia, Ibon; Galveias, Ana; Roldan, NestorAeroallergens or inhalant allergens, are proteins dispersed through the air and have the potential to induce allergic conditions such as rhinitis, conjunctivitis, and asthma. Outdoor aeroallergens are found predominantly in pollen grains and fungal spores, which are allergen carriers. Aeroallergens from pollen and fungi have seasonal emission patterns that correlate with plant pollination and fungal sporulation...
NIR-emitting electrochromic windows for cold climate region buildings
Pinheiro, Daniela; Fernandes, Mariana; Pereira, Rui Francisco Gonçalves Pinto Fernandes; Pereira, Sónia; Correia, Sandra F.H.; Silva, Maria ManuelaElectrochromic devices (ECDs) comprising visible/near-infrared (NIR) transparent amorphous indium zinc oxide (a-IZO) outermost layers and novel NIR-emitting electrolytes are proposed for smart windows of buildings in cold climate regions. The electrolytes are composed of a di-urethane cross-linked poly(oxyethylene)(POE)/siloxane hybrid matrix (d-Ut(600), 600 is the average molecular weight of the POE chains in ...
Conhecimento sobre o regime medicamentoso das pessoas idosas: estudo descritivo
Novais, Sónia; Abreu, Daniela; Magro, Lídia; Gilde, Pedro; Pereira, Sónia; Bastos, Catarina; Carvalhais, MaribelBackground: The aging of the population, with a high incidence of chronic diseases and the prescription of a complex drug regimen requires knowledge and capacity for its effective and safe management. Polymedication, inherent to chronic health conditions, entails complications that may arise from the elderly people's inadequate knowledge about the management of the drug regimen. Objective: To characterize the k...
3D Multi-Material Laser Powder Bed Fusion of 420 stainless steel-Cu parts for P...
Cunha, Ângela Sofia Varela; Marques, Ana Cristina Ribeiro; Silva, Filipe Samuel; Carvalho, Óscar Samuel Novais; Bartolomeu, Flávio; Gasik, MichaelPlastic injection molding is one of the fastest-growing industries in the world. However, although it presents numerous advantages, the costs associated with the mold and machine are high and, therefore, this process is only profitable for mass production. Moreover, the reduction in the cycle time, more specifically the cooling time, has been a never-ending challenge since it has a direct influence on productio...
Inconel 718–Copper bimetallic joints fabricated by 3D multi-material laser powd...
Marques, Ana Cristina Ribeiro; Carvalho, Óscar Samuel Novais; Silva, Filipe Samuel; Bartolomeu, Flávio; Pereira, Sónia; Alexandrino, PauloUsually, aerospace components are subjected to high demanding operating conditions in terms of mechanical and thermal stresses. The structural integrity of these components is assured by the use of high strength and temperature-resistant materials such as Inconel alloys. However, these alloys are known to have low thermal conductivity, which makes it difficult to extract heat from inside the component. Copper-b...
Sol-gel derived di-ureasil based ormolytes for electrochromic devices
Nunes, Paulo Joaquim; Pereira, Rui Francisco Gonçalves Pinto Fernandes; Pereira, Sónia; Silva, Maria Manuela; Fortunato, ElviraTwo di-ureasils incorporating oxyethylene segments with average molecular weights Y = 600 and 900 g mol<sup>−1</sup>, prepared by the sol-gel method, and doped with the ionic liquid 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) and lithium tetrafluoroborate (LiBF<sub>4</sub>) salt were prepared. The as-obtained films are translucent, flexible, and hydrophobic, and have a low level of nanoscale surface roughne...
