Optimizing calibration of fluxgate magnetometer offsets using magnetic holes in the earth’s magnetosheath

Earth, Planets and Space
The offset of the fluxgate magnetometer (FGM) drifts slowly with time and temperature, requiring regular in-flight calibration. Recent studies utilizing magnetic holes have optimized calibration error to ~ 0.3 nT in the solar wind, but an order larger in

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.
