    Bayesian feedback in the framework of ecological sciences by Mario Figueira, Xavier Barber, David Conesa, Antonio López-Quílez, Joaquín Martínez-Minaya, Iosu Paradinas, Maria Grazia Pennino

    Published 2024-12-01
    “…For example, species data can be collected from scientific sampling with a completely random sample pattern, but also from opportunistic sampling (e.g., whale watching from commercial fishing vessels or bird watching from citizen science), where observers tend to look for particular species in areas where they expect to find them.Species Distribution Models (SDMs) are widely used tools for analysing this type of ecological data. …”

    Variations of autonomic arousal mediate the reportability of mind blanking occurrences by Paradeisios Alexandros Boulakis, Nicholas John Simos, Stefania Zoi, Sepehr Mortaheb, Christina Schmidt, Federico Raimondo, Athena Demertzi

    Published 2025-02-01
    “…What remains inconclusive is whether MB can also ensue from autonomic arousal manipulations, pointing to the implication of peripheral physiology to mental events. Using experience sampling, neural, and physiological measurements in 26 participants, we first show that MB was reported more frequently in low arousal conditions, elicited by sleep deprivation. …”
