A patient‐specific 3D model of the knee to compare the femoral rollback before and after total knee arthroplasty (TKA)

Journal of Experimental Orthopaedics, 2021
Purpose Total knee arthroplasty (TKA) is nowadays performed as a standard procedure on a large number of patients suffering from arthrosis. Replacing the knee joint causes changes in the geometry and kinematics of the knee, which are unique to each ...

Physical principles underlying the quantum Hall effect [PDF]

, 2011
In this contribution, we present an introduction to the physical principles underlying the quantum Hall effect. The field theoretic approach to the integral and fractional effect is sketched, with some emphasis on the mechanism of electromagnetic gauge ...

Design and analysis of ultra‐wideband decoupling structure based on polarization mismatch

Electronics Letters
In this work, a polarization rotating surface is designed, analyzed, and applied to the decoupling of ultra‐wideband antennas. A method of using dual‐size combined rings is proposed to expand the operating bandwidth to 4.8 to 18.2 GHz, and the ...

Spatiotemporal Scaling Effect on Rainfall Network Design Using Entropy

Entropy, 2014
Because of high variation in mountainous areas, rainfall data at different spatiotemporal scales may yield potential uncertainty for network design. However, few studies focus on the scaling effect on both the spatial and the temporal scale.
