Gradient-based geometry learning for fan-beam CT reconstruction.

Incorporating computed tomography (CT) reconstruction operators into differentiable pipelines has proven beneficial in many applications. Such approaches usually focus on the projection data and keep the acquisition geometry fixed. However, precise knowledge of the acquisition geometry is essential for high quality reconstruction results.

[Gender and developmental effects on perceived stress, coping, somatic symptoms and psychological disorders among children and adolescents].

The aim of this one-year longitudinal study was to investigate gender and developmental effects on perceived stress related to interpersonal stressors, coping strategies, somatic symptoms and psychological disorders. Additionally, associations of perceived stress and coping styles at the first assessment with psychological problems at the second measurement were examined. In total, N = 169 Austrian children and adolescents (ages 10 to 13 years) participated in this self-report study.
