This article is concerned with a dual mixed formulation of the Navier-Stokes system in a polygonal domain of the plane with Dirichlet boundary conditions and its numerical approximation. The gradient tensor, a quantity of practical interest, is introduced as a new unknown. The problem is then approximated by a mixed finite element method. Quasi-optimal a priori error estimates are obtained. The...

Each year, 4.7 million people are bitten by dogs. Of those bitten each year, 386,000 are seriously injured and some killed. Consequently, many insurance companies refuse to issue homeowners insurance to owners of specific breeds of dogs considered "vicious" or high risk of causing injury. This study examined whether vicious dog owners were different on antisocial behaviors and personality dimen...

The fatal outcome in the case described was unfortunate but was undoubtedly largely attributable to the patient's respiratory condition. The great difficulty which may be encountered in closing the duodenal stump in the presence of massive infiltration must, however, be stressed. We are indebted to Dr. A. A. Miller for valuable assistance with the pathological studies and for helpful advice. RE...

Although the filtered backprojection algorithm (FBA) has been the standard reconstruction algorithm in 2D computerized tomography for more than 30 years, its convergence behavior is not completely settled so far. Relying on convergence results by Rieder and Faridani for the semi-discrete FBA [SIAM J. Numer. Anal., 41(3), 869-892, 2003] we show optimality of the fully discrete version for recons...
