Classification of Seasonal Allergic Rhinitis Patients by Prospective Patient‐Recorded Symptoms: The @IT.2020 Project

Allergy, EarlyView.
Daily prospective symptom reports from participants in this multicentre observational study were compared to retrospective (last 12 months) reports based on ARIA clinical questionnaire. Retrospective reports substantially underestimated, and to a lesser extent overestimated, symptom frequency compared to e‐Diary prospective reports. Since retrospective

Dry eye disease symptoms and associated risk factors in a Norwegian clinical cohort

Acta Ophthalmologica, EarlyView.
Abstract Background The relationship between dry eye disease (DED) symptoms and different demographic, clinical and lifestyle factors remains poorly understood. Norway's cold climate and dry indoor air may accelerate tear evaporation, contributing to a very high meibomian gland dysfunction prevalence, as found in multiple studies.

Step2Motion: Locomotion Reconstruction from Pressure Sensing Insoles

Computer Graphics Forum, EarlyView.
Abstract Human motion is fundamentally driven by continuous physical interaction with the environment. Whether walking, running, or simply standing, the forces exchanged between our feet and the ground provide crucial insights for understanding and reconstructing human movement. Recent advances in wearable insole devices offer a compelling solution for

Walking the walk: Assessing the relative impact of virtual versus actual walks and nature‐based versus urban settings on affect

Environmental Psychology Research, Volume 1, Issue 4, December 2026.
Abstract Background As young people face rising anxiety and depression alongside declining contact with nature, there is growing interest in how the affective benefits of nature‐based settings might be delivered more widely. Methods We conducted two within‐subjects studies comparing four walking conditions across convenient, everyday accessible ...
