Signal and error assessment of GOCE-based high resolution gravity field models
The signal content and error level of recent GOCE-based high resolution gravity field models is assessed by means of signal degree variances and comparisons to independent GNSS-levelling geoid heights. The signal of the spherical harmonic series of these

Transanal Hemorrhoidal Dearterialization (THD): A Single Center Experience on 100 Consecutive Cases
Introduction. Surgeons, using all available means for the treatment of the hemorrhoidal disease, must make compromises between the radicality of the potential surgical treatment (to prevent recurrence) and the maintenance of the postoperative ...

Applying Hpo Indices to Empirical Thermospheric Density Models During Geomagnetic Storms
Abstract Accurate atmospheric drag modeling is essential for precise orbit determination and prediction of Low Earth Orbit satellites. A key component is the thermospheric density, typically estimated using empirical models driven by geomagnetic activity indices such as the 3‐hr Kp or ap.
