4560 Background: The Heng et al JCO 2009 prognostic model was developed in the age of VEGF-targeted therapy and this study serves as an external validation while comparing its performance to other models. METHODS 1,028 previously unanalyzed patients were used to externally validate the prognostic criteria for overall survival (OS). The model's(More)
We discuss several strategies to implement Dykstra's projection algorithm on NVIDIA's compute unified device architecture (CUDA). Dykstra's algorithm is the central step in and the computation-ally most expensive part of statistical multi-resolution methods. It projects a given vector onto the intersection of convex sets. Compared with a CPU implementation(More)
We present two implementations of Dykstra's projection algorithm [1] on NVIDIA's compute unified device architecture (CUDA). Dykstra's algorithm is the central step in statistical multi-resolution (SMR) methods [2,3] which are a recent development for the deconvolution of noisy images. Unlike other methods its primary parameter is the confidence level with(More)
