Advancing EEG classification with transformer architecture: a case study on P300 potentials for assistive devices

Abstract: In this investigation, the Transformer architecture is applied to classify P300 event-related potentials in publicly available EEG data to augment assistive communication devices for individuals with impaired communication abilities. A detailed analysis comparing the Transformer model to established algorithms documented in the literature demonstrates its effectiveness in terms of Leia mais…

Evaluation method for hygrothermal performance of masonry rendering mortars: assessing moisture and mould growth risk under brazilian climate conditions

Abstarct: The presence of moisture in environments, when it exceeds certain limits and is associated with specific temperature ranges, can promote the growth of mould fungi inside buildings, compromising the health of occupants and leading to other harmful pathological manifestations affecting building performance. In this context, rendering mortars with paint Leia mais…

Propriedades e aspectos do concreto aparente do patrimônio da arquitetura moderna brasileira

Resumo: O objetivo do estudo é investigar propriedades e aspectos do concreto aparente das empenas do edifício Vilanova Artigas e correlacioná-los ao estado de conservação, visando oferecer subsídios para preservação. O edifício completou 50 anos em 2019 e foi submetido a reparos estruturais recentemente (2013-2015). Ensaios laboratoriais e observações “in Leia mais…

Using electrical resistivity tomography to understand the hydrogeological behavior of acid drainge percolation in a fractured aquifer at a uranium mining site

Abstract: Brazilian mining ventures aged 30 years or older were studied, revealing historical oversights in environmental planning that have caused substantial environmental liabilities during active mining and decommissioning. Electrical resistivity tomography surveys were conducted in a decommissioning uranium mine in southeast Brazil. The results provided valuable insights into local hydrogeological dynamics, Leia mais…

Chikungunya-driven gene expression linked to osteoclast survival and chronic artharalgia

Abstract: Chikungunya fever (CHIKF), caused by the Chikungunya virus (CHIKV), manifests as acute febrile illness often associated with polyarthritis and polyarthralgia. Although the acute symptoms resolve within two weeks, many patients experience prolonged joint pain and inflammation, resembling rheumatoid arthritis (RA). This study aimed to identify molecular markers related to Leia mais…
