Technology requirements for Summit-Autonomous CustomCornea.

W ith the recent surge of interest in wave-front sensing technology as a new diagnostic tool in refractive surgery 1,2 , the concept of wavefront customized correction has now come to the forefront. 3,4 Among the companies leading this effort, the Summit-Autonomous Technologies provides a technology platform within CustomCornea which can be used as a model for wavefront ablation requirements. A...

Run-DMA

Copying data from devices into main memory is a computationally-trivial, yet time-intensive, task. In order to free the CPU to perform more interesting work, computers use direct memory access (DMA) engines — a special-purpose piece of hardware — to transfer data into and out of main memory. We show that the ability to chain together such memory transfers, as provided by commodity hardware, is ...

Stimulation of Rauscher Leukemia Virus DMA Polymerase DMA-directed DMA Synthesis by Cationic Trypanocides and Polyamines1

Activated DMA-directed DNA synthesis catalyzed by Rauscher leukemia virus (RLV) and other type C mammalian retroviral DNA polymerases is uniquely stimulated by biologically active polyamines. Cationic trypanocides may act as antagonists of polyamine function. As described here, several cationic trypanocides stimulate RLV polymerase-catalyzed DNA-directed DNA synthe sis at concentrations signifi...

Understanding DMA Malware

Attackers constantly explore ways to camouflage illicit activities against computer platforms. Stealthy attacks are required in industrial espionage and also by criminals stealing banking credentials. Modern computers contain dedicated hardware such as network and graphics cards. Such devices implement independent execution environments but have direct memory access (DMA) to the host runtime me...
