Satellite Tracking and Photographic-Identification as Connectivity-Based Tools ...
Weyn, Mieke; Marrero-Pérez, Jacobo; Sánchez Mora, Anna; Pimentel González, Atenary; Ferreira, Rita; Sambolino, Annalisa; Dinis, AnaIdentifying biogeographical patterns and important biological (blue) corridors can greatly contribute to conservation planning. Yet, this is particularly challenging when addressing pelagic species. In this study, satellite telemetry and photographic-identification data of short-finned pilot whales (Globicephala macrorhynchus) were used to identify preferred areas and pathways in the Macaronesia biogeographical...
Using OR-Tools When Solving the Nurse Scheduling Problem
Oliveira, Márcia; Rocha, Ana Maria A.C.; Alves, FilipeScheduling of employees is a common problem that can be found in most organizations all over the world. One example is the nurse scheduling problem (NSP), which is a complex combinatorial opti-mization problem faced by healthcare institutions in assigning working and nonworking days. The NSP comprises constraints for the nurses, for the hospital and considers specific labor regulations, aswell as the skills and...

Platinum resistance temperature detectors for biomedical applications
Retolaza, Aritz; Sotgiu, Edoardo; Ferreira, Gabriel M.; Sousa, Paulo J.; Catarino, Susana Oliveira; Minas, Graça; Alves, Filipe; Dias, Rosana[Excerpt] The rapid advancement in biosensing devices is driven by the growing need to continuously monitor human health data and predict the onset of chronic diseases at an early stage. These devices leverage a variety of sensors designed for continuous monitoring of physiological and biochemical markers, often integrated into wearable or implantable patches [1]. Among these sensors, the temperature sensors ar...
Isotope-based inferences of the trophic niche of short-finned pilot whales in t...
Escánez, Alejandro; Marrero-Pérez, Jacobo; Dromby, Morgane; Pimentel-González, Atenary; Dias, Ester; García-Pastor, Ester M.; Weyn, MiekeKnowledge of predator-prey interactions is key in ecological studies and understanding ecosystem function, yet this is still poorly explored in the deep-sea environment. Carbon (delta C-13: C-13/C-12) and nitrogen (delta N-15: N-15/N-14) stable isotope ratios of a deep-diving species, the short-finned pilot whale (Globicephala macrorhynchus), were used to explore knowledge gaps on its ecological niche and forag...
Vólvulo Gástrico Mesentero-Axial Complicado com Isquemia Gástrica em Idade Adulta
Alves, Filipe; Ribeiro Morgado, Margarida; Araújo, Bruno; Guimarães, Luis; Pereira, André; Madureira, António JoséO vólvulo gástrico mesentero-axial é uma entidade rara, caracterizada por rotação anómala do estômago sobre o seu menor eixo com potencial obstrução do outlet gástrico, que, se não for abordada atempadamente, pode associar-se a significativa morbilidade e mortalidade. Descrevemos o caso clínico de uma mulher de 30 anos de idade que se apresentou com quadro sugestivo de obstrução gastrointestinal com um dia de e...
Investigating the role of symptom valorisation in tuberculosis patient delay in...
de Morais, Margarida; Sousa, Sofia; Marques, Jéssica; Moniz, Marta; Duarte, Raquel; Leite, Andreia; Soares, Patricia; Carreira, Mário; Pereira, SofiaBackground: Diagnosis delay contributes to increased tuberculosis (TB) transmission and morbimortality. TB incidence has been decreasing in Portugal, but median patient delay (PD) has risen. Symptom valorisation may determine PD by influencing help-seeking behaviour. We aimed to analyse the association between symptom valorisation and PD, while characterising individuals who disregarded their symptoms. Methods:...
Capacitated waste collection problem solution using an open-source tool
Silva, Adriano S.; Alves, Filipe; Díaz de Tuesta, Jose Luis; Rocha, Ana Maria A.C.; Pereira, Ana I.; Silva, Adrián; Gomes, HelderPopulation in cities is growing worldwide, which puts the systems that offer basic services to citizens under pressure. Among these systems, the Municipal Solid Waste Management System (MSWMS) is also affected. Waste collection and transportation is the first task in an MSWMS, carried out traditionally in most cases. This approach leads to inefficient resource and time expense since routes are prescheduled or d...
Conceptual multi-agent system design for distributed scheduling systems
Alves, Filipe; Rocha, Ana Maria A.C.; Pereira, Ana I.; Leitão, PauloWith the progressive increase in the complexity of dynamic environments, systems require an evolutionary configuration and optimization to meet the increased demand. In this sense, any change in the conditions of systems or products may require distributed scheduling and resource allocation of more elementary services. Centralized approaches might fall into bottleneck issues, becoming complex to adapt, especial...
Citizen science and expert judgement: A cost-efficient combination to monitor a...
Parretti, Paola; Monteiro, João Gama; Gizzi, Francesca; Martinez-Escauriaza, Roi; Alves, Filipe; Chebaane, Sahar; Almeida, Silvia; Pais, Miguel PessanhaMapping the distribution and evaluating the impacts of marine non-indigenous species (NIS) are two fundamental tasks for management purposes, yet they are often time consuming and expensive. This case study focuses on the NIS gilthead seabream Sparus aurata escaped from offshore farms in Madeira Island in order to test an innovative, cost-efficient combined approach to risk assessment and georeferenced dispersa...
