Tasdizen, Tolga | Automatic markup of neural cell membranes using boosted decision stumps | To better understand the central nervous system, neurobiologists need to reconstruct the underlying neural circuitry from electron microscopy images. One of the necessary tasks is to segment the individual neurons. For this purpose, we propose a supervised learning approach to detect the cell membra... | | 2009 |

Myers, Chris J. | A standard-cell self-timed multiplier for energy and area critical synchronous systems | This paper describes the design of a standard-cell self-timed multiplier for use in energy and area critical synchronous systems. The area of this multiplier is bounded by N rather than N2 as seen in more traditional combinational parallel array designs, where N is the word size. Energy has a polyn... | | 2001 |

Myers, Chris J. | Timed circuit verification using TEL structures | Abstract-Recent design examples have shown that significant performance gains are realized when circuit designers are allowed to make aggressive timing assumptions. Circuit correctness in these aggressive styles is highly timing dependent and, in industry, they are typically designed by hand. In ord... | | 2001 |

Stringfellow, Gerald B. | Surface photo-absorption studies of the chemical structure of GaInP grown by organometallic vapor phase epitaxy | The surface structure of Ga0.52In0.48P was studied by surface photoabsorption. An absorption peak due to P dimers on Ga0.52In0.48P was observed at 400 nm, shorter than for InP (430 nm). From comparison with results for GaAs and InP, the data are interpreted to indicate that at a tertiarybutylphos... | Absorption peak; Ordering; Substrate orientation | 1995 |
