Is full-automation in radiotherapy treatment planning ready for take off?
Callens, Dylan; Malone, Ciaran; Carver, Antony; Fiandra, Christian; Gooding, Mark J; Korreman, Stine S; Matos Dias, Joana; Popple, Richard ARadiotherapy treatment planning is undergoing a transformation with the increasing integration of automation. This transition draws parallels with the aviation industry, which has a long-standing history of addressing challenges and opportunities introduced by automated systems. Both fields witness a shift from manual operations to systems capable of operating independently, raising questions about the risks an...

A stochastic method for exploiting outranking relations in multicriteria choice...
Dias, Luís C.; Rocha, HumbertoThe multicriteria decision aiding field offers many methods to support decision makers in comparing a list of alternatives. Among these, outranking methods such as ELECTRE are appreciated for avoiding full compensation among criteria, but outranking relations are difficult to exploit due to incompleteness and lack of transitivity. This work focuses on choice problems, proposing a stochastic exploitationmethod t...

Reflections on beam configuration optimization for intensity-modulated proton t...
Cao, Wenhua; Rocha, Humberto; Mohan, Radhe; Lim, Gino; Goudarzi, Hadis M; Ferreira, Brígida C; Dias, Joana Maria Pina Cabral MatosPresumably, intensity-modulated proton radiotherapy (IMPT) is the most powerful form of proton radiotherapy. In the current state of the art, IMPT beam configurations (i.e. the number of beams and their directions) are, in general, chosen subjectively based on prior experience and practicality. Beam configuration optimization (BCO) for IMPT could, in theory, significantly enhance IMPT's therapeutic potential. H...
Population density impact on COVID-19 mortality rate: A multifractal analysis u...
Pascoal, R; Rocha, HumbertoThe current COVID-19 pandemic caught everyone off guard and is an excellent case study to investigate the real impact of population density on emerging highly contagious infectious diseases. The relationship between the threat of COVID-19 and population density has been widely debated not only in scientific articles, but also in magazines and reports around the world. It appeared both in the columns of experts ...
