A black-box solver for the solution of nonlinear functional equations is a compromise of exibilty, eeciency and stability of the algorithms. We will present a general form of functional equation, a general error indicator and the eecient interaction of the error indicator and the Newton-Raphson iteration during the solution of the problem arising from the(More)
Recovery after total hip arthroplasty (THA) is influenced by several psychological aspects, such as depression, anxiety, resilience, and personality traits. We hypothesized that preoperative depression impedes early functional outcome after THA (primary outcome measure). Additional objectives were perioperative changes in the psychological status and their(More)
