Recommendations for the implementation of a national lung cancer screening prog...
Fernandes, M. G. O.; Dias, M.; Santos, R.; Ravara, S.; Fernandes, P.; Firmino-Machado, J.; Antunes, J. P.; Fernandes, O.; Madureira, A.; Hespanhol, V.Lung cancer (LC) is a leading cause of cancer-related mortality worldwide. Lung Cancer Screening (LCS) programs that use low-dose computed tomography (LDCT) have been shown to reduce LC mortality by up to 25 % and are considered cost-effective. The European Health Union has encouraged its Member States to explore the feasibility of LCS implementation in their respective countries. The task force conducted a com...
Adaptando políticas e programas de preparação das pessoas às realidades locais:...
Dias, M.; Diogo, M.; Samora-Arvela, A.; Barreiros, J.Em Portugal, após os incêndios rurais de 2017, onde se verificou a perda de 117 vidas humanas e estimou-se um prejuízo de 1,5 bilhões de euros, o Governo de Portugal avançou com a criação de legislação para promover a implementação de programas de autoproteção nas comunidades rurais. Surge, assim, no ano de 2018, os programas “Aldeia Segura, Pessoas Seguras” (ASPS). Estes programas não são inéditos em Portugal,...
Confronting Vegard's rule in Ge1-x Sn (x) epilayers: from fundamentals to the e...
Magalhaes, S.; Dias, M.; Nunes, B.; Oliveira, F.; Cerqueira, M. F.; Alves, E.Comprehensive and systematic study challenging the application of Vegard's rule to germanium tin solid solutions grown on germanium buffer layers and 100 silicon substrates is presented. The binary's lattice parameters, composition and respective uncertainties are determined through x-ray diffraction via reciprocal space mapping technique employing newly developed software. The tin content is confirmed by Ruthe...
Five-dimensional f(R) braneworld models
Hoff Da Silva, J. M. [UNESP]; Dias, M.Made available in DSpace on 2022-04-29T01:14:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-09-30; After incorporating f(R) gravity into the general braneworld sum rules scope, it is shown that some particular class of warped five-dimensional nonlinear braneworld models, which may be interesting for the hierarchy problem solution, still require a negative tension brane. For other classes of warp fact...
A tutorial approach on mass dimension one fermions phenomenological analysis
Duarte, Laura [UNESP]; Dias, M.; de Campos, F. [UNESP]Made available in DSpace on 2021-06-25T10:11:21Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-09-01; The mass dimension one spinor is a candidate to explain the dark matter content in our universe. This field is an eingenspinor of charge conjugation operator and has a peculiar mass dimension, which restricts its renormalizable interactions with the particles. As a dark matter candidate, its generic sig...
Revisiting the minimal universal extra dimensions with mass-dimension-five oper...
Dias, M.; Duarte, Laura [UNESP]; de Campos, F. [UNESP]Made available in DSpace on 2021-06-25T10:56:15Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-01; We examine a minimally modified version of the minimal universal extra dimension, using electric and magnetic dipole moments and Higgs portals operators to describe new interactions between fermionic dark matter and Standard Model particles. We assume the dark matter in the form of weakly interacting ma...
Fungal contamination and azole-resistance in tea and other medicinal plants com...
Simões, A.; Faria, M.; Dias, M.; Viegas, Carla; Caetano, Liliana AranhaIntroduction. Tea and infusions are common beverages worldwide, prepared by infusing Camellia sinensis or other medicinal plants (eg. Melissa officinalis) with boiling water. Contamination by specific strains of filamentous fungi, such as Aspergillus sp., may originate health risks. While azole antifungal drugs are first-line therapy against fungal infections, the exposure of medicinal plants to azole fungicide...
Mass-dimension-one fermions and their gravitational interaction
Bueno Rogerio, R. J.; Lima, R. De C. [UNESP]; Duarte, L. [UNESP]; Hoff Da Silva, J. M. [UNESP]; Dias, M.; Senise, C. R.Made available in DSpace on 2020-12-12T01:16:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; We investigate in detail the interaction between the spin-(1/2) field endowed with mass dimension one and the graviton. We obtain an interaction vertex that combines the characteristics of scalar-graviton and Dirac's fermion-graviton vertices, due to the scalar-dynamic attribute and the fermionic struct...
DisKnow: a social-driven disaster support knowledge extraction system
Boné, J.; Dias, M.; Ferreira, J. C.; Ribeiro, R.This research is aimed at creating and presenting DisKnow, a data extraction system with the capability of filtering and abstracting tweets, to improve community resilience and decision-making in disaster scenarios. Nowadays most people act as human sensors, exposing detailed information regarding occurring disasters, in social media. Through a pipeline of natural language processing (NLP) tools for text proces...
Named entity recognition for sensitive data discovery in Portuguese
Dias, M.; Boné, J.; Ferreira, J.; Ribeiro, R.; Maia, R.The process of protecting sensitive data is continually growing and becoming increasingly important, especially as a result of the directives and laws imposed by the European Union. The effort to create automatic systems is continuous, but, in most cases, the processes behind them are still manual or semi-automatic. In this work, we have developed a component that can extract and classify sensitive data, from u...
