Becoming activists: How young athletes use visual tools for civic action and me...
Vieira, D.; Dias, T. S.; Sampaio, M.; Pais, S. C.; Ribeiro, N.; Nada, C.; Malafaia, C.How can participatory research, combined with visual methods, enable young people to grow as engaged citizens in their communities? This article introduces an innovative methodological design that draws on a Youth Participatory Action Research (YPAR) approach with 33 young athletes aged 11 to 16 from two different educational settings. Based on both observation notes from the community profiling process and vis...
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...
Two-loop renormalisation of gauge theories in 4D implicit regularisation and co...
Cherchiglia, A.; Arias-Perdomo, D. C.; Vieira, A. R.; Sampaio, M.; Hiller, B.We compute the two-loop β-function of scalar and spinorial quantum electrodynamics as well as pure Yang–Mills and quantum chromodynamics using the background fieldmethod in a fully quadridimensional setup using implicit regularization (IREG). Moreover, a thorough comparison with dimensional approaches such as conventional dimensional regularization (CDR) and dimensional reduction (DRED) is presented. Subtleties...
“Uma praça em cada bairro” program: Analysis and contribution to the requalific...
Narciso, J.; Sampaio, M.The traditional role of the urban public space has shifted during the 20th century and in particular throughout the post-second world war. The global trend to adjust the public space to the car traffic and parking needs was observed in Lisbon as in many other industrialized cities. By the end of the century, some projects to value public space through the pedestrianization of streets were attempted without sign...
Top condensation model: a step towards the correct prediction of the Higgs mass
Osipov, A. A.; Hiller, B.; Blin, A. H.; Palanga, F.; Moreira, J.; Sampaio, M.A realization of the composite Higgs scenario in the context of the effective model with the SU(2)L ×U(1)R symmetric four-Fermi interactions proposed by Miransky, Tanabashi and Yamawaki is studied. The model implements Nambu’s mechanism of dynamical electroweak symmetry breaking leading to the formation of ¯tt and ¯ bb quark condensates. We explore the vacuum structure and spectrum of the model by using the Sch...
Avaliação de websites de hotéis do ponto de vista do marketing digital
Sampaio, M.; Alturas, B.; Fernandes, A. L.A evolução das Tecnologias da Informação alterou radicalmente a forma como as empresas da indústria hoteleira se relacionam com os clientes. A internet permitiu um aumento da participação no mercado, sobretudo de pequenos e médios empreendimentos, e hoje é considerada uma das principais ferramentas de comunicação e venda para as empresas dessa indústria. Sendo assim, este trabalho teve por objetivo aferir a qua...
