From structural design to model compression: Research progress on lightweight algorithms for motor imagery brain–computer interfaces

Abstract Motor imagery brain–computer interfaces (MI‐BCIs) enable direct brain‐to‐device communication by decoding movement intentions from EEG signals. Although deep learning models have significantly improved decoding accuracy, their high computational complexity and large para...

User engagement behaviours with identity-disclosed social bots on social media: the role of perceived human–machine differences

Purpose This study examines how users interpret identity-disclosed social bots on social media, how perceived human–machine differences shape psychological response orientations and how these orientations are enacted through visible engagement behaviours. Design/methodology/appro...

AI for inclusion: a powerful idea – under which conditions?!

Purpose This opinion piece explores the social, organisational, and political conditions under which artificial intelligence (AI) can genuinely foster inclusion for people with disabilities and other marginalised groups. While AI shows clear potential in fields such as rehabilita...

Trial-level pupil dynamics reflect attention-related variability and medication-associated modulation in ADHD

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) often exhibit rapid fluctuations in attention that are difficult to capture using standard behavioural assessments. We investigated whether trial-level pupil dynamics provide a physiological signal associated with task...

Peak Shaving and Valley Filling: Reconstructing Cognitive Load in Cultural Heritage VR Through Contextualized Scaffolding

Virtual reality supports immersive cultural heritage communication, yet engagement outpaces understanding. A structural cause is that information about an object is scattered across transient carriers (NPC dialogue, annotations, triggered videos), requiring working-memory integra...

Colorectal cancer-derived IGFBP2 promotes liver metastasis by driving intrahepatic fibrotic pre-metastatic niche formation

Colorectal cancer (CRC) liver metastasis (LM) is a leading cause of cancer-related death, with pre-metastatic niche (PMN) formation being critical for metastasis. Insulin-like growth factor binding protein 2 (IGFBP2) is overexpressed in metastatic CRC, but its role in intrahepati...
