New Late Cretaceous and Central Atlantic Magmatic Province magmatic sources off...
Terrinha, Pedro; Neres, Marta; Noiva, João; Brito, Pedro; Rosa, Marcos; Batista, Luis; Ribeiro, CarlosThis work investigates the existence and tectonic control of magmatic bodies in the continental shelf of the SW Iberia margin. Magnetic data were densely acquired for a total area of ~4400 km2 and carefully processed. Our new maps reveal a complex magnetic anomaly field, where distinct zones are defined based on the anomaly distribution. A wide number and variety of magmatic bodies are interpreted, from >10 km-...
Post-rift tectono-sedimentary evolution of the deep West Iberian Margin.
Simões, Maria; Roque, Cristina; Ribeiro, Carlos; Noiva, João; Terrinha, PedroThe West Iberian Margin (WIM) is the conjugate margin of the Grand Banks of Canada and the rifting processes that originated both margins have been widely studied over the last decades. Therefore, WIM is well known as a classical example of a non-volcanic rifted margin with two main rifting phases related to the North Atlantic opening. Despite the studies carried out so far, the knowledge about the sedimentary ...

Terrinha, Pedro; Duarte, João; Ribeiro, Carlos; Pereira, Helder; Correia, Gina; Sousa, MonicaNa Bacia Algarvia, sector ocidental de Sagres-Lagos encontra-se o registo tectonoestratigráfico de rifting, do Triásico (~220 Ma) ao Cretácico inferior terminal (Albiano, ~100Ma). As séries estratigráficas deste sector da Bacia Algarvia são condensadas, registando numa espessura inferior a 0.5 km o registo sedimentar Mesozóico local de 120 milhões de anos. Por oposição na Bacia offshore no Algarve Central o reg...

Firm internationalization and activity impact on digital technologies adoption
Ribeiro, Carlos; Gomes, SofiaThe study explores the complex relationship between the adopting of digital technology, corporate internationalization, and sector-specific insights. It assesses how different levels of digital technology adoption are apparent in different activities. This way, the study involves two distinct models, analyzing seven key digital technologies. To this end, a quantitative methodology was applied to 16,365 companie...
The Impact of Digital Imaging Tools and Artificial Intelligence on Self-Reporte...
Dawa, Hossam; No-Cortes, Juliana; Peñarrocha-Diago, Miguel; Vicente, Henrique; Ribeiro, Carlos; Cortes, ArthurBackground: The integration of digital imaging tools in dentistry has transformed clin-ical workflows, diagnostic accuracy, and patient outcomes. However, less attention has been given to how these tools influence dentists’ self-reported outcomes, including clinical confidence, efficiency, perceived treatment quality, communication, and pro-fessional satisfaction. This article aimed at assessing AI-powered digi...
Caracterização geoquímica da diagénese em dentes de saurópodes como suporte aos...
da Silva, Roberto; Camilo da Silva, Bruno; Cáceres Balbino, Ausenda; Barrulas, Pedro; Barrocas Dias Teixeira da Costa, Mafalda; Ribeiro, CarlosRESUMO: Foram realizados estudos mineralógicos e geoquímicos detalhados (μ-XRD, μ-XRF, SEM-EDS, LA-ICP-MS), em dentes de saurópodes do Jurássico Superior do sector central da Bacia Lusitaniana. Destes, a μ-XRD revelou uma constituição mineralógica consistente das amostras (hidroxiapatite) e a μ-XRF comprovou que a composição química dos dentes estudados é dominada pelo Ca e P, com pequenas concentrações de Fe, ...
Integrating Generative Artificial Intelligence in Clinical Dentistry: Enhancing...
Dawa, Hossam; Cortes, Arthur; Ribeiro, Carlos; Neves, José; Vicente, HenriqueGenerative artificial intelligence (GAI) is poised to transform clinical dentistry by enhancing diagnostic accuracy, personalizing treatment planning, and improving procedural precision. This study integrates logic programming and entropy within knowledge representation and reasoning to generate hypotheses, quantify uncertainty, and support clinical decisions. A six-month longitudinal questionnaire was administ...
Preliminary assessment of CO2 storage potential of deep saline aquifers in the ...
Pedro, Jorge; Moita, Patricia; Ribeiro, Carlos; Kilpatrick, Andrew; Edlmann, Katriona; Wilkinson, Mark; Afonso, Paula; Barradas, João; Carneiro, JúlioThe reduction of atmospheric CO2 through its safe geological storage, as CCUS techniques is one of the goals to achieve the 2050 commitment. Within the scope of thePILOTSTRATEGY project, two sedimentary sequences Triassic (on-shore) and Cretaceous (off shore) were object of a detailed study in order to evaluate their potential as CO2storage complexes in the Lusitanian basin (west Portuguese margin). A multi-dis...
Falência vacinal secundária contra o sarampo: casos identificados em 2024
Neves, Raquel; Ribeiro, Carlos; Palminha, PaulaPortugal alcançou o estatuto de eliminação do sarampo em 2015, no entanto, continuam a ocorrer surtos esporádicos, incluindo casos em indivíduos previamente vacinados. O teste de avidez das IgG avalia a força de ligação das imunoglobulinas ao seu antigénio específico, a qual aumenta ao longo da resposta imunitária, permitindo assim distinguir infeções primárias de respostas imunes pré-existentes. Este estudo te...
