Wavelength Tunability of Ion-bombardment Induced Ripples on Sapphire
, 2006 A study of ripple formation on sapphire surfaces by 300-2000 eV Ar+ ion bombardment is presented. Surface characterization by in-situ synchrotron grazing incidence small angle x-ray scattering and ex-situ atomic force microscopy is performed in order to ...

Spectral modelling of force ripples in permanent magnet bearingless motors
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2016 Purpose The purpose of this paper is to propose an analytical model for the calculation of forces ripples in bearingless permanent magnet motor. Design/methodology/approach The model is based on a spectral modeling of the forces based on a spectral analysis of the air-gap flux density. Findings The proposed methodology allows the prediction of the

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
