Vila Nova de Cerveira-Goián defensive subsystem, at Minho river valley, within ...

This paper focuses on the Vila Nova de Cerveira-Goián Defensive Subsystem, within a wider structured defensive network that runs along the border course of the Minho River Valley. Built along the borders of the Portuguese territory during the Restoration War (1640-1668), this landscape results from the advances, retreats and constant actions of attack and defence from both Iberian armies, evidencing successive ...

Non-invasive derivation of instantaneous free-wave ratio from invasive coronary...

Invasive coronary physiology is underused and carries risks/costs. Artificial Intelligence (AI) might enable non-invasive physiology from invasive coronary angiography (CAG), possibly outperforming humans, but has seldom been explored, especially for instantaneous wave-free Ratio (iFR). We aimed to develop binary iFR lesion classification AI models and compare them with human performance. single-center retrospe...

This paper presents the research work within the international Consortium Alliance "Universitas Montium" (UNITA) according one of many UNITA’s Research Projects: the Portuguese Project CH-RESILIENCE “Cultural Heritage: Resilience of Built Heritage and Built Environment” at the University of Beira Interior (UBI) within Universitas Montium Aliance which is included in UNITA's Research & lnnovation Cartography WP4...

Ferroelectric behavior arising from polar topologies in epitaxially strained Sr...

In this work, we show that epitaxially strained SrTiO3-δ thin films, grown by ion-beam sputtering onto (001)Nb: SrTiO3 substrates, exhibit a ferroelectric behavior. At the atomic-scale, through high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) images, it was possible to identify the presence of polar nanoregions with non-trivial polar topological structures in the SrTiO3-δ fil...

Coronary intravascular lithotripsy effectiveness and safety in a real-world cohort

Background: Coronary artery calcification is a predictor of adverse outcomes after percutaneous coronary intervention (PCI). Intravascular lithotripsy (IVL) is a promising tool for the treatment of calcified lesions. The aim of this study was to assess the effectiveness and safety of IVL. Methods: A single-center observational study of PCI procedure, with assessment of the outcomes of patients undergoing PCI us...

A single dose of COVID-19 vaccine induces a strong T cell and B cell response i...

A broad understanding on how SARS-CoV-2 infection and vaccination mobilize the immune system is necessary to find the best predictors of long-term protection and identify individuals that would benefit from additional vaccine doses. This study aims to understand the effect of a single dose of Pfizer-BioNTech BNT162b2 COVID-19 vaccine, in individuals recovered from SARS-CoV-2 infection, on circulating CD4+ T fol...

Sistema defensivo abaluartado no vale do Rio Minho: identificação das técnicas ...

Durante a Guerra da Restauração (1640-1668), em Portugal, foi implementada uma rede de sistemas fortificados abaluartados ao longo da fronteira terrestre e atlântica. Partindo desta circunstância, este artigo toma o sistema defensivo abaluartado implementado ao longo do Vale do Rio Minho, concretamente sobre os elementos militares do concelho de Valença para identificar, caracterizar e debater práticas e técnic...
