Multipath interference impact due to fiber mode coupling in C+L+S multiband tra...
Cancela, L.; Pires, J.Multiband transmission is, nowadays, being implemented worldwide to increase the optical transport network capacity, mainly because it uses the already-installed single-mode fiber (SMF). The G.654E SMF, due to its attributes (e.g., low-loss, and large-effective area in comparison with the standard G.652 SMF), can also increase network capacity and can also be used for multiband (MB) transmission. Nevertheless, ...

Rainho, D.; Pires, J.; Catela, David; Vasconcellos, F.; Brito, L.; Cruz, D.; Silva, E.; Silva, F.; Santos, G.; Mercê, Cristiana; Branco, Marco A. C.Fintar é adquirível e aperfeiçoável através de exercitação específica. Foi objetivo deste estudo verificar se um programa de exercícios específicos propiciaria melhoria de execução técnica qualitativa de 3 fintas básicas do futebol, em escalões de formação. Doze benjamins (B) (10,58±,52 anos; experiência-3,58±1,56 anos) e 16 infantis (I) (11,25±,58 anos; experiência-3,62±1,96 anos), praticaram ao longo de 6 ses...
Comparative analysis of the toxicity profile of eleven consumer-relevant nanoma...
Pires, J.; Moreira, L.; Teixeira, J. P.; Fraga, S.Background: The growing number of items incorporating nanomaterials (NM) has prompted considerable concerns about human health and safety [1]. Metal nanoparticles, inorganic non-metallic, and carbon-based NM are among the types with the highest market volume [2]. Objective: The purpose of this study was to determine the effect of chemical composition [Ag, Au, TiO2, SiO2, and graphene oxide (nano_GO)], primary s...

3D Multi-Material Laser Powder Bed Fusion: a disruptive approach to design/manu...
Bartolomeu, Flávio; Carvalho, O.; Pires, J.; Cunha, A.; Marques, A.; Gasik, M.; Silva, Filipe Samuel[Excerpt] Engineering has been so far a mono-dimension tool where components are mono-material, dense unoptimized and designed for one or two requirements, due to processes’ limitations. Traditional components diverge entirely from lightweight and multi-material nature structures endowed with a high level of multi-functionality. [...]
3D Multi-Material-Selective-Laser-Melting: technology, fabrication and prototypes
Bartolomeu, Flávio; Pires, J.; Marques, A.; Cunha, A.; Carvalho, O.; Gasik, M.; Silva, F. S.[Excerpt] Contrarily to nature, human traditional strategies and inventions both from process and products point of view, use brute force, heavy and inefficient, single and inanimate material (like brick, steel and glass) solutions with unoptimized architectures [1] . To create and developed superior engineering solutions, advanced manufacturing technologies are necessary to evolve from mono-material to multi-m...
May the four be with you: novel IR-subtraction methods to tackle NNLO calculations
Torres Bobadilla, W. J.; Sborlini, G. F. R.; Banerjee, P.; Catani, S.; Cherchiglia, A. L.; Cieri, L.; Dhani, P. K.; Driencourt-Mangin, F.; Engel, T.In this manuscript, we report the outcome of the topical workshop: paving the way to alternative NNLO strategies (https://indico.ific.uv.es/e/WorkStop-ThinkStart_ 3.0), by presenting a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies to deal with infrared and ultraviolet singularities in quantum field theories...
Comparative assessment of the acute toxicity of commonly used metal nanoparticl...
Pires, J.; Moreira, L.; Teixeira, João; Fraga, SóniaMetal nanoparticles (M-NP) have application in several areas such as industry, environment, agriculture, and biomedicine. Consequently, human exposure to these nanosized materials is increasing, which raises serious concerns regarding their safety to the human health and the environment. Biological barriers are important lines of defence to xenobiotics, thus expected targets for M-NP. The present study investig...
In vitro acute toxicity of metal-based nanoparticles in human trophoblast BeWo ...
Pires, J.; Moreira, L.; Teixeira, J.P.; Fraga, S.Metal nanoparticles (M-NP) are among the most widely used nanomaterials in consumer products available in the market. Thus, human exposure to these nanosized materials is increasing, which raises serious concerns regarding their environmental and human safety. Biological barriers are important lines of defence to xenobiotics, thus expected targets for M-NP. In this regard, special consideration must be given to...
Applying the skew-normal distribution to model coherent MPI and to evaluate its...
Cancela, L.; Pires, J.We statistically model the coherent multipath interference (MPI) using an extended skewnormal distribution, with the results showing a good agreement with published experimental data. This distribution is very flexible and permits to model data with large skewness values, which is a typical feature in coherent MPI histograms. Furthermore, the developed model was applied to estimate the impact of coherent MPI on...
