    Article
    Open Access
    We present a comprehensive framework for studying and leveraging morphological symmetries in robotic systems. These are intrinsic properties of the robot’s morphology, frequently observed in animal biology and robotics, ...
  • MPACT: Mesoscopic profiling and abstraction of crowd trajectories 

    Lemonari, Marilena; Panayiotou, Andreas; Kyriakou, Theodoros; Pelechano Gómez, Núria; Chrysanthou, Yiorgos; Aristidou, Andreas; Charalambous, Panayiotis (John Wiley & sons, 2025-01-01)
    Article
    Open Access
    Simulating believable crowds for applications like movies or games is challenging due to the many components that comprise a realistic outcome. Users typically need to manually tune a large number of simulation parameters ...
  • SoftBinReduce: data reduction for color quantization through soft binning 

    Rodríguez i Corominas, Guillem; Blesa Aguilera, Maria Josep; Blum, Christian Clemens (2025-04-16)
    Article
    Open Access
    In this paper, we propose SoftBinReduce, a data reduction method for Color Quantization. Our approach consists of four main steps: (1) identifying representatives in each channel, (2) generating three-dimensional bins, (3) ...
  • Simplifying deep temporal difference learning 

    Gallici, Matteo; Fellows, Mattie; Ellis, Benjamin; Pou Mulet, Bartomeu; Masmitja Rusiñol, Ivan; Foerster, Jakob Nicolaus; Martín Muñoz, Mario (OpenReview.net, 2025)
    Conference report
    Open Access
    Q-learning played a foundational role in the field reinforcement learning (RL). However, TD algorithms with off-policy data, such as -learning, or nonlinear function approximation like deep neural networks require several ...
  • Can personality traits affect sleep quality in post-COVID-19 patients? 

    Carnes Vendrell, Anna; Piñol Ripoll, Gerard; Ariza González, Mar; Cano Marco, Neus; Segura Fàbregas, Bàrbara; Junqué Plaja, Carme; Béjar Alonso, Javier; Barrué Subirana, Cristian; Garolera Freixa, Maite (Multidisciplinary Digital Publishing Institute (MDPI), 2025-04-23)
    Article
    Open Access
    Objectives: In the present study, we aimed (i) to describe the personality traits of a cohort of post-COVID-19 condition (PCC) patients compared with a healthy control (HC) group, (ii) to evaluate the relationship between ...
  • How to represent landmark trees in digital 3D maps? An automated workflow and user study 

    Grammatikaki, Angeliki; Eschner, Johannes; Ledermann, Florian; Argudo Medrano, Óscar; Waldner, Manuela (2025-05-09)
    Article
    Open Access
    Digital 3D maps created from digital elevation models (DEMs) cannot properly capture trees due to the 2.5D nature of the DEMs. Leveraging publicly available DEMs and orthophotos as the only input data sources, we present ...
  • A minimal base or a direct base? That is the question! 

    Baixeries i Juvillà, Jaume; Napoli, Amedeo (2025-11)
    Article
    Open Access
    In this paper we revisit the problem of computing the closure of a set of attributes given a basis of dependencies or implications. This problem is of main interest in logics, in the relational database model, in lattice ...
  • STRATUM project: AI-based point of care computing for neurosurgical 3D decision support tools 

    Fabelo Gómez, Himar; León Martín, Raquel; Torti, Emanuele; Marco Sola, Santiago; Badouh, Asaf; Verbers, Max; Vega García, Carlos; Santana Nuñez, Javier; Cervero García, Teresa; Moretó Planas, Miquel (Elsevier, 2025-07)
    Article
    Open Access
    Integrated digital diagnostics are transforming complex surgical procedures, with brain tumour surgery being among the most challenging. STRATUM, a five-year Horizon Europe-funded project, aims to develop an advanced 3D ...
  • Metacognitive training for psychosis (MCT): a systematic meta-review of its effectiveness 

    Meinhart, Antonia; Sauvé, Geneviève; Schmueser, Annika; Penney, Danielle; Berna, Fabrice; Gaweda, Lukasz; Lamarca, María; Moritz, Steffen; Ochoa, Susana; König, Caroline; Acuña, Vanessa; Fischer, Rabea (Nature, 2025-04-22)
    Article
    Open Access
    Objective Metacognitive training for psychosis (MCT) targets cognitive biases implicated in the pathogenesis of psychosis, e.g., jumping to conclusions, overconfidence in errors, and inflexibility. This systematic meta-review ...
  • Terrain descriptors for landscape synthesis, analysis and simulation 

    Argudo Medrano, Óscar; Guerin, Eric; Schott, Hugo; Galin, Eric (John Wiley & sons, 2025-04-15)
    Article
    Open Access
    Synthetic landscape generation is an active research area within Computer Graphics. Algorithms for terrain synthesis and ecosystem simulations often rely on simple descriptors such as slope, light accessibility, and drainage ...
