Understanding youth preferences for a mentorship program for celiac disease: A qualitative study
JPGN Reports, EarlyView.Abstract Objective Celiac disease (CeD) is an autoimmune condition triggered by gluten ingestion that causes intestinal inflammation and multiple symptoms. Management requires strict adherence to a gluten‐free diet (GFD), yet youth with CeD on a GFD report lower quality of life (QoL) and higher rates of depression and anxiety.

Blended Wing Body Design in UNICADO
Abstract This paper presents a sizing and design methodology for the conceptual phase of blended wing body (BWB) aircraft. The proposed design framework provides a sized and trimmed lifting body with predefined longitudinal stability. Starting from a specified sizing point and cabin geometry, a four-segment lifting body planform is constructed.

Using art history to explore society's changing connections with agriculture
PLANTS, PEOPLE, PLANET, EarlyView.Food insecurity is a looming challenge that especially affects those least fortunate. Consumer food choices have a substantial impact on the sustainability of current food systems. Here, we use art as a lens through which to consider our contemporary and historical relationship to one of the world's most crucial crops, the potato, in the context of the
