Cyclins and cyclin-dependent kinases (Cdks) are the main components that control the orderly progression through cell cycle. In the mature nervous system, terminally differentiated neurons are permanently withdrawn from cell cycle, as mitotic quiescence is essential for the functional stability of the complexly wired neuronal system. Recently, we(More)

We have demonstrated a record gate delay of 2 ps/stage in a 17-stage ring oscillator fabricated in a 170 GHz f/sub t/, 150 GHz f/sub max/ InP HBT technology. Stable operation was achieved for both normal and higher order ring modes. We performed basic circuit time constant analysis as well as detailed computer simulations, and arrived at calculated gate(More)
Perceptual experts are defined by their ability to make fast and accurate identifications of objects within their domain of expertise at specific levels of categorization (Tanaka & Taylor, 1991). Researchers have previously applied a multidimensional space (MDS) framework to better understand the psychological similarities of members of the same object or(More)
