Emotional arousal predicts pupil responses following a single attention shift between bright and dark moving stimuli

Pupil size is widely used as an index of emotional arousal but is also strongly influenced by luminance and attention to bright or dark stimuli. We examined whether trial-by-trial subjective emotional ratings predicted pupil responses when affective sound onset coincided with a s...

FvGI–FvCO–FvFT1 pathway activates FvTFL1 in long days to repress flowering in woodland strawberry ( Fragaria vesca )

Photoperiod is a stable seasonal signal. Although photoperiodic flowering is well understood in short-day (SD) and long-day (LD) annual plants, the regulatory mechanisms in perennials remain elusive. In a perennial woodland strawberry (Fragaria vesca), flowering is induced in SDs...

The aim of this research is to identify the radiological protection problems after the Fukushima accident from the citizens’ perspective and to clarify the major points which should be included in the revised General Recommendations. As research methods, both qualitative and quan...

Near-infrared self-written waveguide spot size converter for single- and multichannel fiber-to-chip self-coupling

Near-infrared (NIR) light-induced self-written (LISW) optical waveguide technology provides passive alignment between telecommunications and silicon photonic devices and offers high-throughput and self-alignment advantages. Although fiber-to-chip self-coupling based on the NIR LI...

Designing Epistemic Partnerships with Generative AI: A Four-Stage Model of Student Engagement in Scientific Argumentation

Abstract This study examined how a design-based learning environment supported first-year undergraduates’ ( N = 31) epistemic engagement with generative AI in a science argumentation course. A two-year design-based research (DBR) study was conducted across two cycles (2024: n = 1...
