A Saturation-Based Method for Primary Resonance Control of Flexible Manipulator
When primary resonance occurs, even a small external disturbance can abruptly excite large amplitude vibration and deteriorate the working performance of a flexible manipulator. Most active control methods are effective for non-resonant vibration but not

Performance of magnetic resonance elastography in primary sclerosing cholangitis [PDF]
AbstractBackground and Aim:Liver stiffness (LS) measured by magnetic resonance elastography (MRE) is emerging as an important biomarker in chronic liver diseases. We examined the diagnostic performance of MRE, factors associated with an increased LS and the prognostic value of LS as measured by MRE among patients with primary sclerosing cholangitis ...
