Foweya Gee 2006

open access: yes, 2021
Foweya Gee, 2006 Gee (2006) recognized the close resemblance between Parastenhelia anglica and Karllangia tertia and removed both species from their respective genera and placed them in a newly proposed genus Foweya. Both Foweya anglica (Norman & Scott, 1905) and F.

Sample size determination for GEE analyses of stepped wedge cluster randomized trials

open access: yesBiometrics, 2018
In stepped wedge cluster randomized trials, intact clusters of individuals switch from control to intervention from a randomly assigned period onwards. Such trials are becoming increasingly popular in health services research.

Estimating Forest Stock Volume in Hunan Province, China, by Integrating In Situ Plot Data, Sentinel-2 Images, and Linear and Machine Learning Regression Models

open access: yesRemote Sensing, 2020
The forest stock volume (FSV) is one of the key indicators in forestry resource assessments on local, regional, and national scales. To date, scaling up in situ plot-scale measurements across landscapes is still a great challenge in the estimation of ...

Piezoelectric Biomaterials for Bone Regeneration: Roadmap from Dipole to Osteogenesis

open access: yesAdvanced Science, EarlyView.
Piezoelectric biomaterials convert mechanical forces into electrical signals, offering novel strategies to restore and modulate bone microenvironments for tissue engineering. This review examines molecular dipole origins, spatial arrangements, and pseudo‐piezoelectric mechanisms and highlights dipole‐engineering techniques for osteogenesis regulation ...
