  • Seeing confusion through a new lens: on the impact of atoms of confusion on novices’ code comprehension 
    da Costa, José Aldo Silva A.S.; Gheyi, Rohit; Castor, Fernando; de Oliveira, Pablo Roberto Fernandes R.F.; Ribeiro, Márcio; Fonseca, Baldoino (Springer, 2023-05-18)
    Code comprehension is crucial for software maintenance and evolution, but it can be hindered by tiny code snippets that can confuse the developers, called atoms of confusion. Previous studies investigated how atoms impact ...
  • The cities we need: Towards an urbanism guided by human needs satisfaction 
    Cardoso, Rodrigo; Sobhani, Ali; Meijers, Evert (SAGE Publications Ltd, 2022-10)
    This article proposes moving beyond the tyranny of economic imperatives towards a human needs-based framework to assess cities and envision their development. Existing calls for such a transition lack a foundation able to ...
  • Examining pathways linking rural labour outflows to the abandonment of arable land in China 
    Chen, Lili; Meadows, Michael; Liu, Ye; Lin, Yanliu (John Wiley and Sons Ltd, 2022-01)
    Against the backdrop of increasing rural labour outflow in China, the marginalisation of agriculture and arable land abandonment has become prevalent. Previous studies have examined the linkages between rural labour outflow ...
  • Scaling Up the Explanation of Multidimensional Projections

    During the 2015 sudden rise in migration movements in Europe, approximately 2.4 million refugees arrived in Europe and 1.2 million asylum applications were received in the European Union countries. We were interested in ...
  • Preventing alloimmunization using a new model for matching extensively typed red blood cells 
    van de Weem, Ronald H.G.; Wemelsfelder, Merel L.; Luken, Jessie S.; de Haas, Masja; Niessen, René W.L.M.; van der Schoot, C. Ellen; Hoogeveen, Han; Janssen, Mart P. (Wiley-Blackwell, 2022-04)
    Background and Objectives: Alloimmunization is a well-known adverse event associated with red blood cell (RBC) transfusions, caused by phenotype incompatibilities between donor and patient RBCs that may lead to haemolytic ...
  • Synthesising Reward Machines for Cooperative Multi-Agent Reinforcement Learning 
    Varricchione, Giovanni; Alechina, Natasha; Dastani, Mehdi; Logan, Brian (2023-09-07)
    Reward machines have recently been proposed as a means of encoding team tasks in cooperative multi-agent reinforcement learning. The resulting multi-agent reward machine is then decomposed into individual reward machines, ...
  • Measuring the quality of projections of high-dimensional labeled data 
    Benato, Bárbara; Falcao, Alexandre; Telea, Alex (Elsevier Limited, 2023-11)
    Dimensionality reduction techniques, also called projections, are one of the main tools for visualizing high-dimensional data. To compare such techniques, several quality metrics have been proposed. However, such metrics ...
  • The effects of the interaction of genetic predisposition with lifestyle factors on bladder cancer risk 
    Yu, Evan Yi Wen; Liu, Yu Xiang; Chen, Ya Ting; Tang, Qiu Yi; Mehrkanoon, Siamak; Wang, Shi Zhi; Li, Wen Chao; Zeegers, Maurice P.; Wesselius, Anke (Wiley-Blackwell, 2023-04)
    Objectives: To investigate the association of polygenic risk score (PRS) and bladder cancer (BC) risk and whether this PRS can be offset by a healthy lifestyle. Methods: Individuals with BC (n = 563) and non-BC controls ...
  • The effectiveness of bovine tuberculosis surveillance in Dutch badgers 
    Orrico, Mario; van Schaik, Gerdien; Koets, Ad; van den Broek, Jan; Montizaan, Margriet; La Haye, Maurice; Rijks, Jolianne M. (Wiley, 2022-07)
    Countries survey wildlife for bovine tuberculosis (bTB) to ensure case detection or to ascertain a high probability of freedom from bTB in wildlife. The Eurasian badger (Meles meles) is a potential bTB reservoir host. ...
  • The Flow of Trust: A Visualization Framework to Externalize, Explore, and Explain Trust in ML Applications 
    van der Elzen, Stef; Andrienko, Gennady L.; Andrienko, Natalia; Fisher, Brian; Martins, Rafael; Peltonen, Jaakko; Telea, Alex; Verleysen, Michel (IEEE Computer Society, 2023-03-01)
    We present a conceptual framework for the development of visual interactive techniques to formalize and externalize trust in machine learning (ML) workflows. Currently, trust in ML applications is an implicit process that ...
