Association between anticoagulation strategy and quality of life in chronic hemodialysis patients

open access: yesScientific Reports, 2023
Prevention of clotting in hemodialysis (HD) is a concern, but tools to monitor anticoagulation strategies as well as data on bleeding and its impact on quality of life (QoL) are scant.

Exploration of the X-ray Dark-Field Signal in Mineral Building Materials

open access: yesJournal of Imaging, 2022
Mineral building materials suffer from weathering processes such as salt efflorescence, freeze–thaw cycling, and microbial colonization. All of these processes are linked to water (liquid and vapor) in the pore space. The degree of damage following these

Multi-frame DVC for temporal image sequences

open access: yesFrontiers in Materials, 2022
Digital volume correlation (DVC) is a 3D image-based technique for displacement and strain computation. Traditionally, both (digital image correlation) DIC and DVC are methods based on two individual time frames; the estimation of the displacement and ...
