For the series associated to a group or coset R.C.F.T. there is a simple universal form for the inverse of the handle operator in the ring of fusions. These formulae may be easily understood from the quantization of the associated Chern-Simons theory.

OBJECTIVE To determine the potential indications for placement of cartilaginous alar rim grafts in primary and revision septorhinoplasty. METHODS Retrospective medical chart analysis of all patients undergoing septorhinoplasty from March 2003 through June 2004 in a private facial plastic and reconstructive surgery center and a tertiary teaching hospital. Patients who received alar rim grafts ...

BACKGROUND Studies on intracardiac echocardiography for transcatheter closure of secundum atrial septal defect (ASD) only include ASDs ≤38mm diameter without rim deficiency. AIMS To assess transcatheter closure of complex ASDs under intracardiac echocardiography guidance. METHODS Retrospective study from January 2006 to January 2012 in all consecutive adult patients referred to our centre f...

Osteonecrotic collapse of the femoral head is a common refractory disease in orthopedics, and the occurrence of collapse is an important factor in the prognosis of this condition. Osteonecrotic collapse of the femoral head can be delayed or prevented by the formation of a sclerotic rim. This study used finite element analysis to evaluate the mechanical role of a proximal sclerotic rim on stress...

The paper proposes a general optimization model with separable strictly convex objective function to obtain the consistent OWA (ordered weighted averaging) operator family. The consistency means that the aggregation value of the operator monotonically changes with the given orness level. Some properties of the problem are discussed with its analytical solution. The model includes the two most c...
