Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Although age is a known predictor of outcomes following total knee arthroplasty (TKA), most large‐scale studies rely on registry data that lack clinical detail and combines multiple implant designs. This study aimed to determine whether age has an independent effect on implant survivorship and clinical outcomes when a single TKA design

Managerial and Decision Economics, EarlyView.ABSTRACT Exchanges in franchise systems are embedded in the level of trust that exists in franchisee–franchisor relationships. Although trust is essential in business relationships, it can unfold a negative side effect on the appreciation of exchange in these relationships as hidden costs of trust.

Dual Variational Problems and Action Principles for Chen–Lee and Hopf–Langford Systems
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We describe the construction of dual variational principles and action functionals for nonlinear dynamical systems using a methodology based on the dual Lagrange multiplier formalism and a convex optimization approach, to derive families of dual actions that correspond to the given nonlinear ordinary differential system.

Time‐Division Multiplexing for Parallel Transmission at Ultra‐High Field With Limited RF Channels
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Investigating time‐division multiplexing for parallel transmission in ultra high‐field imaging, striving for homogeneous whole brain excitation with a limited number of RF channels. Methods A fast RF switch was built to alternately route 8 transmit channels to each row of a double‐row 16‐element transmit coil array at a 9.4 T human MRI
