We report our results after ten year follow-up of 107 consecutive ABG-I hip prostheses implanted between June 1990 and December 1992: Only 84 prostheses were still in the study after ten years, but only six patients had undergone surgical revision. We can consider our clinical outcomes as excellent, with a whole-implant survival rate greater than 96%, a(More)
This study describes the 2-year follow-up of Bankart reconstruction in 44 patients with post-traumatic recurrent anterior instability of the shoulder, using suture anchors and reinforcing the repair with a subscapularis overlap. Forty-three of 44 patients (98%) regained normal stability. One recurrent dislocation occurred. The mean loss of external rotation(More)
The use of dyadic interaction between agents, in combination with homophily (the principle that "likes attract") in the Axelrod model for the study of cultural dissemination, has two important problems: the prediction of monoculture in large societies and an extremely narrow window of noise levels in which diversity with local convergence is obtained.(More)
A new model is proposed, in the context of Axelrod's model for the study of cultural dissemination, to include an external vector field (VF) which describes the effects of mass media on social systems. The VF acts over the whole system and it is characterized by two parameters: a nonnull overlap with each agent in the society and a confidence value of its(More)
We present a model to find analytically the electronic states in self-assembled quantum dots with a truncated spherical cap ('lens') geometry. A conformal analytical image is designed to map the quantum dot boundary into a dot with semi-spherical shape. The Hamiltonian for a carrier confined in the quantum lens is correspondingly mapped into an equivalent(More)
Moment based methods have produced efficient multiscale quantization algorithms for solving singular perturbation/strong coupling problems. One of these, the Eigenvalue Moment Method (EMM), developed by Handy etverging lower and upper bounds to a specific discrete state energy, once the signature property of the associated wavefunction is known. This method(More)
