In this paper we investigate the use of discriminatively trained feature transforms to improve the accuracy of a MAP-SVM language recognition system. We train the feature transforms by alternatively solving an SVM optimization on MAP supervectors estimated from transformed features, and performing a small step on the transforms in the direction of the antigradient of the SVM objective function....

A method of generating Deep Shadow Maps from a 3D data set is presented. This method uses ray tracing on the GPU to accumulate opacity and store them in a deep shadow map. The deep shadow map is then sampled based on view direction to determine how much light got to a particular fragment. The shadow maps can also be used to cast shadows onto other objects.

The origin and direction of replication of the resistance plasmid R100.1 and its resistance transfer factor derivative, pAR132, were studied by electron microscopy autoradiography of partially denatured molecules and partial denaturation mapping of replicative intermediates. Results of these studies indicate the existence of an origin of replication at 8.8 kilobases on the R100 map. Replication...
