Energy-consistent discretization of viscous dissipation with application to natural convection flow

Sanderse, Benjamin · Trias Miquel, Francesc Xavier

2025Publisher: ElsevierRepository: UPCommons — Universitat Politècnica de Catalunya

A new energy-consistent discretization of the viscous dissipation function in incompressible flows is proposed. It is implied by choosing a discretization of the diffusive terms and a discretization of the local kinetic energy equation and by requiring that continuous identities…

Perspectives of medicine, human biology, and nursing undergraduates on transversal skills learning: a mixed-methods study

Silva Fontana-Rosa, Nathalia · González de Paz, Luis · Codina Rodríguez, Ana C. + 2 authors

2025Repository: UPCommons — Universitat Politècnica de Catalunya

Background. In health sciences practice, interpersonal skills, critical thinking, and learning-to-learn are crucial transversal skills. Effective teaching necessitates the understanding of undergraduates’ views. This study explored undergraduate experiences in human biology…

Amazonian manatee critical habitat revealed by artificial intelligence-based passive acoustic techniques

Erbs, Florence Amandine · Van der Schaar, Mike Connor Roger Malcolm · Marmontel, Miriam + 3 authors

2025Publisher: John Wiley & sonsRepository: UPCommons — Universitat Politècnica de Catalunya

For many species at risk, monitoring challenges related to low visual detectability and elusive behavior limit the use of traditional visual surveys to collect critical information, hindering the development of sound conservation strategies. Passive acoustics can…

A dataset of synthetic, maturation-informed magnetic resonance images of the human fetal brain

Lajous, Hélène · Le Boeuf Fló, Andrés · Gordaliza, Pedro M. + 5 authors

2025Publisher: NatureRepository: UPCommons — Universitat Politècnica de Catalunya

Magnetic resonance imaging (MRI) is a powerful modality for investigating abnormal developmental patterns in utero. However, since it is not the first-line diagnostic tool in this sensitive population, data remain scarce and heterogeneous across scanners and hospitals. To…
