 | This thesis explores the forensic opportunities afforded by flash memory. It starts with a discussion of flash storage starting with the physics of flash devices, the development of flash translation layers (which allow flash devices to be used with unmodified legacy operating systems), and flash file systems (which provide for better utilization of flash storage at a somewhat higher cost). Then this thesis provides a comprehension survey of the relevant ... |

| CD4+CD25+FoxP-3+ regulatory T-cells (Tregs) suppress immune responses to 'self' antigens, but also have been shown to suppress host anti-tumor responses in several human malignancies, including breast, gastrointestinal, and ovarian cancer. Identification of CML Tregs as suppressors of host anti-CML responses could have a significant impact upon CML treatment strategies. Methods are currently available to selectively suppress Tregs and subsequently boost host anti-CML responses. We have examined the CD4+CD25+FoxP-3+ regulatory T-cell ... |

| Complexity of the channel is beneficial for time reversal communications. After multichannel combining, each user signal is processed with a single channel decision feedback equalizer (DFE) to remove any residual intersymbol interference (ISI) and compensate for channel fluctuations during the packet transmission. This same approach can be applied in a synthetic aperture context where multiple transmissions (separated spatially) substitute for multiple receive elements. As an alternative to the passive time ... |
