Behavioral risk models explain locomotor and balance changes when walking at virtual heights.

Walking in daily life requires humans to adapt to environments that can influence one's fear of falling and anxiety about a potential fall. In such environments, individuals may adopt compensatory locomotor and balance changes to maintain a constant expected risk function equal to the product of the probability of some event (e.g.

Understanding determinants of lung cancer preventive care in at-risk urban American Indians and Alaska Natives: A mixed-methods study.

Introduction: Lung cancer is the leading cause of cancer death among American Indian and Alaska Native (AI/AN) people, and AI/AN people have the highest rate of smoking of any racial or ethnic group in the US. There is limited research to inform culturally-relevant strategies for lung cancer prevention inclusive of lung cancer screening (LCS). The objective of this study was to understand determinants of LCS and tobacco cessation care in at-risk urban-dwelling AI/ANs.

Effects of water-table changes following rainfall events on arsenic fate and transport in groundwater-surface water mixing zones.

This study investigated the effects of groundwater-surface water (GW-SW) interactions on the fate and transport of arsenic (As) following rainfall events and subsequent water-table changes in GW-SW mixing zones, comprising the riparian and hyporheic zones, near an abandoned gold mine. During the dry and wet periods, stream conditions changed from flow-through to gaining, respectively. Water-table changes caused by rainfall events controlled flow paths between riparian zones and the stream, affecting spatiotemporal variation in the redox and pH conditions of the aquatic environment.

3D Printed Cardiac Models as an Adjunct to Traditional Teaching of Anatomy in Congenital Heart Disease-A Randomised Controlled Study.

Introduction: Three-dimensional (3D) printed cardiac models are increasingly being used for medical education, simulation and training, communication, surgical planning and research. Given the complexities of congenital cardiac anatomy, 3D printing is well suited as an adjunct to traditional teaching methods. This study aims to explore the influence of 3D printed cardiac models as a teaching aid for nurses and paediatric trainees.
