Differences between Two Methods to Stabilize Supramalleolar Osteotomies in Children—A Retrospective Case Series

open access: yesChildren, 2021
Supramalleolar osteotomy (SMO) in pediatric patients can be fixed in various ways. We analyzed the records of 77 pediatric patients (124 SMOs) aged ≤16 years. In 56 patients (96 SMOs), K-wires were used to stabilize SMOs (WF group), while 21 patients (28

Estimating Gravimetric Water Content of a Winter Wheat Field from L-Band Vegetation Optical Depth

open access: yesRemote Sensing, 2019
A considerable amount of water is stored in vegetation, especially in regions with high precipitation rates. Knowledge of the vegetation water status is essential to monitor changes in ecosystem health and to assess the vegetation influence on the water ...

On-Ground Characterization of the SMOS Payload [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2009
The on-ground characterization of the synthetic aperture radiometer onboard the Soil Moisture and Ocean Salinity mission is described. Characterization includes basic functionality, internal calibration, thermal cycling, response to point and flat sources, self-radio-frequency interference, and others.

Evaluation of Satellite-Derived Surface Soil Moisture Products over Agricultural Regions of Canada

open access: yesRemote Sensing, 2020
Soil moisture is a critical indicator for climate change and agricultural drought, but its measurement is challenging due to large variability with land cover, soil type, time, space and depth.
