— Cloud computing has emerged in recent years as a major segment of the IT industry; however, security concerns remain the primary impediment to full-scale adoption. Leveraging properties of virtualization, virtual machine introspection (VMI) has yielded promising research for cloud security yet adoption of these approaches in production environments(More)
We report a simple technique that allows obtaining mid-infrared absorption spectra with nanoscale spatial resolution under low-power illumination from tunable quantum cascade lasers. Light absorption is detected by measuring associated sample thermal expansion with an atomic force microscope. To detect minute thermal expansion we tune the repetition(More)
