Quantum theory of plasmon-phonon scattering in multisubband systems
Ribeiro, Sofia; Terças, HugoWe present a first-principles quantum theory of a critical yet unexplored energy-loss pathway in low-dimensional semiconductors: resonant second-order scattering between multisubband (MSB) plasmons mediated by longitudinal optical phonons. Specifically, we demonstrate how a high-energy MSB plasmon decays into a lower-energy plasmon state via phonon emission-a fundamental process governing energy relaxation and ...
Traumatic versus Non-Traumatic Spinal Cord Injury: Complications and Functional...
Pereira, Patrícia; Tizón, Sónia; Freixo, Sara; Ribeiro, Sofia; Almeida, Gabi; Sousa, JoãoIntroduction: This retrospective cohort study aimed to compare demographic differences, functional outcomes, duration of stay (DOS), and complication profiles between patients with traumatic (TSCI) and non-traumatic (NTSCI) spinal cord injuries in an acute inpatient rehabilitation service. Methods: This study included 128 spinal cord injury patients, 68 with traumatic and 60 with nontraumatic lesions, admitted ...
KAFKA AND PORTUGUESE MICROFICTION: INTERCONNECTIONS AND INTERTEXTUAL APPROACHES...
Ribeiro, SofiaAs a sub-genre with scarce representation in the Portuguese literary field, microfiction nevertheless maintains a revealingly productive dialogue with Kafka’s short fiction, which manifests itself in the narrative architecture, in the choice of isolated characters oscillating between vigilance and paranoia, in the visual writing, in the exploration of the unusual and of the bleak oneiric, in the construction of...
Artificial intelligence in human resources: trends and competencies
Meirinhos, Viviana; Ribeiro, SofiaArtificial Intelligence (AI) has emerged as a transformative force across various industries, and Human Resource Management (HRM) is no exception. The implementation of AI tools is profoundly altering critical processes in the employee lifecycle, such as Recruitment and Selection, Onboarding, Training and Development, Performance Evaluation, and Talent Retention. This study aimed to explore the key trends in th...
Functional Outcome in an Inpatient Rehabilitation Setting After Post-Intensive ...
Ribeiro, Sofia; Almeida, Gabi; Raposo, Ana Rita; Pereira, Patrícia; Freixo, Sara; Soares, Ivone; Gemelgo, Cláudia; Martins Pereira, FátimaIntroduction: Coronavirus disease 2019 (COVID-19) can cause acute respiratory distress syndrome and acute respiratory failure, requiring hospitalization. The complications and functional consequences of hospitalization at intensive-care units (ICU) are called post-intensive care syndrome (PICS). This study aimed to describe functional outcomes in patients with PICS due to COVID-19 and evaluate the factors that ...
Transcranial Magnetic Stimulation–Electroencephalography (TMS-EEG) in neurosurg...
Oliveira, Martim; Ribeiro, Sofia; Baig Mirza, Asfand; Vastani, Amisha; Díaz-Baamonde, Alba; Tanaka, Masumi; Elhag, Ali; Marchi, FrancescoBackground: Transcranial Magnetic Stimulation–Electroencephalography (TMS-EEG) is a non-operative technique that allows for magnetic cortical stimulation (TMS) and analysis of the electrical currents generated in the brain (EEG). Despite the regular utilization of both techniques independently, little is known about the potential impact of their combination in neurosurgical practice. Methods: This scoping revie...
Decoding Sentiments about Migration in Portuguese Political Manifestos (2011, 2...
Marino, Erik; Vieira, Renata; Baleato, Jesus; Ribeiro, Sofia; Laken, KatarinaThis research conducts a mixed-method analysis of Portuguese political manifestos from 2011, 2015, and 2019, focusing on immigration discourse. We employed Natural Language Processing (NLP) sentiment analysis, with a Multilingual BERT model, alongside qualitative examination of key statements. Findings indicate a generally positive sentiment towards migration among mainstream parties, consistently with Portugal...
Critically ill patient mortality by age: long-term follow-up (CIMbA-LT)
Gonçalves-Pereira, João; Oliveira, André; Vieira, Tatiana; Rodrigues, Ana Rita; Pinto, Maria João; Pipa, Sara; Martinho, Ana; Ribeiro, SofiaBackground The past years have witnessed dramatic changes in the population admitted to the intensive care unit (ICU). Older and sicker patients are now commonly treated in this setting due to the newly available sophisticated life support. However, the short- and long-term benefit of this strategy is scarcely studied. Methods The Critically Ill patients’ mortality by age: Long-Term follow-up (CIMbA-LT) was a m...
Enterococcus spp. from chicken meat collected 20 years apart overcome multiple ...
Rebelo, Andreia; Duarte, Bárbara; Ferreira, Carolina; Mourão, Joana; Ribeiro, Sofia; Freitas, Ana R.; Coque, Teresa M.; Willems, Rob; Corander, JukkaPoultry meat has been a vehicle of antibiotic resistant bacteria and genes. Yet, the diversity of selective pressures associated with their maintenance in the poultry-production chain remains poorly explored. We evaluated the susceptibility of Enterococcus spp. from chicken meat collected 20 years apart to antibiotics, metals, acidic pH and peracetic acid-PAA. Contemporary chicken-meat samples (n = 53 batches, ...
Remote Work and Data Protection: How do Organisations Secure Personal Data Prot...
Ribeiro, SofiaIn the Information Society, business processes tend to become increasingly digital and operate in the virtual world. With the recent pandemic, this transformation has become almost mandatory. With their workers performing their duties remotely, organisations feel the need to digitally adapt their processes. Among several aspects of concern in these transmutations, one stands out: data protection. How can data p...
