Neutrophil-to-lymphocyte ratio as a prognostic marker in highly PD-L1 expressin...
Gomes, Lídia; Pereira, Samuel; Dias, Joana; Figueiredo, Ana Maria; Barata, FernandoIntroduction and objectives: The neutrophil-lymphocyte ratio (NLR) has been proposed to assess advanced stage non-small cell lung cancer (aNSCLC) response to immunotherapy, given the easy availability and low cost. The aim of our study was to evaluate the relationship between NLR at baseline, after the 3rd and 6th treatment cycles, and progression free survival (PFS) and overall survival (OS), in a population w...
Microphone array for speaker localization and identification in shared autonomo...
Marques, Ivo Cruz; Sousa, João; Sá, Bruno Vilaça; Costa, Diogo; Sousa, Pedro; Pereira, Samuel; Santos, Afonso Manuel Macedo; Lima, CarlosWith the current technological transformation in the automotive industry, autonomous vehicles are getting closer to the Society of Automative Engineers (SAE) automation level 5. This level corresponds to the full vehicle automation, where the driving system autonomously monitors and navigates the environment. With SAE-level 5, the concept of a Shared Autonomous Vehicle (SAV) will soon become a reality and mains...
Bao-Enclave: virtualization-based Enclaves for Arm
Pereira, Samuel; Sousa, João; Pinto, Sandro; Martins, José Carvalho; Cerdeira, David MartinsGeneral-purpose operating systems (GPOS), such as Linux, encompass several million lines of code. Statistically, a larger code base inevitably leads to a higher number of potential vulnerabilities and inherently a more vulnerable system. To minimize the impact of vulnerabilities in GPOS, it has become common to implement security-sensitive programs outside the domain of the GPOS, i.e., in a Trusted Execution En...
Characterisation and evaluation of the mechanical behaviour of endodontic-grade...
Pereira, Samuel; Carvalho, André; Reis, Luis; Freitas, Manuel; Montalvao, DiogoWith the introduction of new materials and advances in medical science, the endodontic files have changed since the early days of root canal treatments. In the late days, we have seen an increasing use of Nickel-Titanium (NiTi) alloys. At body temperature, NiTi alloys present a superelastic behaviour, which allows to be more effective in the removal of the tooth pulp tissue, and in the protection of the tooth s...

Pereira, Samuel; Carvalho, André; Reis, Luís; Freitas, Manuel; Montalvão, DiogoThe orthodontic files have been used in dentistry since the middle ages and, as so, the shape, material and operation mode have changed since those days. In the late days, we have seen an increasing use of Nickel-Titanium (NiTi) alloys, to the detriment of more conventional alloys. At body temperature, these NiTi alloys present a superelastic behaviour, which allow the file to follow the teeth root in an easier...
