Power And Hotspot Modeling For Modern GPUs
… The trade-offs among performance, power, and heat must be well modeled and evaluated from the early stage of GPU design. This necessitates a tool that allows GPU architects to quickly and accurately evaluate their design. There are a few models for GPU power but most of them estimate power at …

Nuclear PTEN Regulates Thymidylate Biosynthesis and Cellular Sensitivity to Antifolate Treatment
… of research for this dissertation. Looking at a heat map of all 5 cell lines, it was clear nuclear PTEN stood out and followed a different and opposite pattern to that of wildtype and cytoplasmic membrane PTEN. This led us to compare nuclear PTEN to vector PTEN null cell lines and determine which …
