Purpose: With the widespread introduction of dual energy computed tomography (DECT), applications utilizing the spectral information to perform material decomposition became available. Among these, a popular application is to decompose contrast-enhanced CT images into virtual non-contrast (VNC) or virtual non-iodine images and into iodine maps. In 2021, photon-counting CT (PCCT) was introduced, which is another spectral CT modality.

Self-efficacy is relevant in explaining performance and well-being in different domains of human behaviour. Despite this need, there are no instruments that assess self-efficacy in university teaching in virtual environments. Therefore, the objective of this study was to design the Self-Efficacy Scale for University Teaching in Virtual Environments (SSUTVE) and analyse its psychometric properties.

The transition to virtual learning formats during the COVID-19 pandemic necessitated substantial curricular adjustments to the University of Hawai'i John A. Burns School of Medicine. This study compares student satisfaction and academic performance between the pre-pandemic (up through March 25, 2020) and pandemic (after March 25, 2020) periods.

Evaluating the contribution of microstructure to overall bone strength is tricky since it is difficult to control changes to pore structure in human or animal samples. We developed an open-source program that can generate three-dimensional models of micron-scale cortical bone. These models can be highly customized with a wide array of variable input parameters to allow for generation of samples with high similarity to CT scans of cortical bone or with specific geometric features.

Introduction: Upper limb (UL) impairment is common in people with multiple sclerosis (pwMS), and functional recovery of the UL is a key rehabilitation goal. Technology-based approaches, like virtual reality (VR), are increasingly promising. While most VR environments are task-oriented, our clinical approach integrates neuroproprioceptive 'facilitation and inhibition' (NFI) principles.
