A robust method of identifying moving or changing objects in a video sequence groups each pixel with other adjacent pixels according to either motion or intensity values. Pixels are then repeatedly regrouped into clusters in a hierarchical manner. As these clusters are regrouped, the motion pattern .....

Background:In order to maximize capacity carried in fiber-optic communication systems, spectrally efficient modulation formats are being intensely investigated. One such modulation format is called Nyquist-WDM (Wavelength Division Multiplexing) which results in a rectangular-like spectrum and concur.....

Fast access time is a fundamental requirement while employing flash for system usage. As flash storage capacity doubles every two years, improvements in read speed are required to cope with the growing desired data transfer rates. Flash enhancements have been suggested, such as aggressive scaling, w.....

ER stress, elicited by chemotherapeutic agents such as doxorubicin, 5FU, vincristine and bortezomib, or statins such simvastatin, triggers cell death at least in part through generation of leukotriene C4 (LTC4), which induces ROS accumulation, DNA damage and subsequent cell death. LTC4 can be produc.....
