The finishing space value for shooting decision-making in high-performance foot...
Caldeira, N.; Lopes, R. J.; Araújo, D.; Fernandes, D.Football players’ decision-making behaviours near the scoring target (finishing situations) emerge from the evolving spatiotemporal information directly perceived in the game’s landscape. In finishing situations, the ball carrier’s decision-making about shooting or passing is not an individual decision-making process, but a collective decision that is guided by players’ perceptions of match affordances. To sust...
Exploring the prevalence and antibiotic resistance profile of Klebsiella pneumo...
Araújo, D.; Castro, J.; Matos, F.; Oliveira, R.; Ramos, C.; Almeida, Carina Manuela Fernandes; Silva, Sónia CarinaKlebsiella spp. is an important pathogen in humans and animals and due to the indiscriminate use of antibiotics, its prevalence and antibiotic resistance has increased in companion animals. The main goal of this study was to investigate the prevalence and antibiotic resistance of Klebsiella spp. isolated from clinically ill cats and dogs admitted in veterinary clinics in the North of Portugal. A total of 256 cl...
From optical tracking to tactical performance via Voronoi diagrams: Team format...
Caldeira, N.; Lopes, R. J.; Fernandes, D.; Araújo, D.Football performance behaviour relies on the individual and collective perceptual attunement to the opportunities for action (affordances) available in a given competitive environment. Such perception–action coupling is constrained by players’ spatial dominance. Aiming to understand the influence of team formation and players’ roles in their dynamic interaction (interpersonal linkages), Voronoi diagrams were us...
The soccer game, bit by bit: An information-theoretic analysis
Pereira, L. R.; Lopes, R. J.; Louçã, J.; Araújo, D.; Ramos, J.In this article, we present an original method to measure the rate of positional change observed during a soccer match based on the relative spatial distribution of players on the pitch. This is justified as play- ers use their relative position as a key tactical tool to contribute to their team’s objectives. A temporal network representation of the game was used, where nodes are players discretely clustered by...
Real-world data from the Portuguese Nivolumab Expanded Access Program (EAP) in ...
Figueiredo, A.; Almeida, M.A.; Almodovar, M.T.; Alves, P.; A, Araujo; Araújo, D.; Barata, F.; Barradas, L.; Barroso, A.; Brito, U.; Camacho, E.Objective: The main aim of the study was to evaluate the efficacy and safety profile of Nivolumab, an immune-checkpoint-inhibitor antibody, in advanced, previously treated, Non-Small Cell Lung Cancer (NSCLC) patients, in a real world setting. Methods: We performed a retrospective, multicentre data analysis of patients who were included in the Portuguese Nivolumab Expanded Access Program (EAP). Eligibility crite...
A multilevel hypernetworks approach to capture properties of team synergies at ...
Ribeiro, J.; Silva, P.; Davids, K.; Araújo, D.; Ramos, J.; Lopes, R. J.; Garganta, J.Previous work has sought to explain team coordination using insights from theories of synergy formation in collective systems. Under this theoretical rationale, players are conceptualised as independent degrees of freedom, whose interactions can become coupled to produce team synergies, guided by shared affordances. Previous conceptualisation from this perspective has identified key properties of synergies, the...
Interactions between soccer teams reveal both design and emergence: cooperation...
Ramos, J.; Lopes, R. J.; Araújo, D.Considering soccer matches as complex systems facilitates the identification of properties that emerge from the interactions between players. Such properties include the regularities and statistical patterns that characterize couplings and sets between players established during matches. Empirical studies on the statistical distributions of number of items (e.g., words in texts) have shown that these distribu- ...
Using optical tracking system data to measure team synergic behavior: Synchroni...
Daniel, C.; Couceiro, M. S.; Brito, J.; Figueiredo, P.; Lopes, R. J.; Araújo, D.The ecological dynamics approach to interpersonal relationships provides theoretical support to the use of kinematic data, obtained with sensor-based systems, in which players of a team are linked mainly by information from the performance environment. Our goal was to capture the properties of synergic behavior in football, using spatiotemporal data from one match of the 2018 FIFA WORLD CUP RUSSIA, to explore t...
A multilevel hypernetworks approach to capture meso-level synchronisation proce...
Ribeiro, J.; Lopes, R. J.; Silva, P.; Araújo, D.; Barreira, D.; Davids, K.; Ramos, J.; Maia, J.; Garganta, J.Understanding team behaviours in sports performance requires understanding the interdependencies established between their levels of complexity (micro-meso-macro). Previously, most studies examined interactions emerging at micro- and macro-levels, thus neglecting those emerging at a meso-level (reveals connections between player and team levels, depicted by the emergence of coordination in specific sub-groups o...
Predictors and outcomes of disseminated tuberculosis in an intermediate burden ...
Meira, L.; Chaves, Catarina; Araújo, D.; Almeida, L.; Boaventura, R.; Ramos, A.; Carvalho, T.; Osório, Nuno S.; Castro, António G.Setting: University-affiliated hospital located in Porto, North Portugal, an area with a low to intermediate incidence of tuberculosis (TB). Objective: To identify predictors and outcomes of disseminated TB (dTB). Design: A cohort of patients diagnosed with TB between 2007 and 2013 was retrospectively analysed. Patients with dTB criteria were characterized and compared to single organ TB cases. Factors independ...
