Palladium/hydrogen catalyzed alcoholysis of benzylsilanes
(Elsevier: Journal of Organometallic Chemistry, 1976)Certain benzylsilanes are converted to methoxy or ethoxysilanes and toluene when treated with methanol or ethanol in the presence of hydrogen and catalytic amounts of palladium on charcoal. The reaction is promoted by a ... -
Papillomavirus DNA replication
(Humana Press: Methods in Molecular Medicine, 1999-09)Papillomavirus genomes replicate and are maintained as stable extrachromosomal plasmid DNA (episomes) in many cell lines. This process requires the viral E1 and E2 proteins and the origin of replication. The minimal origin ... -
Paracrystal model of the high-temperature lamellar phase of a ternary microemulsion system
(Blackwell Publishing : Journal of Applied Crystallography, 1991-10-01)Small-angle neutron scattering was used to investigate the microstructure of the high-temperature L-alpha phase in the AOT/water/decane system [AOT = sodium bis(2-ethylhexyl) sulfosuccinate]. The system was modeled as ... -
Paradoxical shifts in human color sensitivity caused by constructive and destructive interference between signals from the same cone class
(Cambridge University Press, 2006-05)Paradoxical shifts in human color (spectral) sensitivity occur on deep-red (658 nm) background fields. As the radiance of the deep-red background is increased from low to moderate levels, the spectral sensitivity for ... -
Parametric analysis of target/decoy performance
(The International Society for Optical Engineering (SPIE), 1991-04-01)As infrared sensing technology matures and the development of space-based optical sensors becomes feasible, interest has grown in protecting both ballistic and orbiting objects from detection by optical sensors. Such ... -
The Parsec-scale radio structure of NGC 1068 and the nature of the nuclear radio source
(American Astronomical Society, 2004-10-01)We present sensitive, multifrequency Very Long Baseline Array (VLBA2) images of the nuclear radio sources of NGC 1068. At 5 GHz and 8.4 GHz, the radio continuum source S1, argued to mark the location of the hidden active ... -
Partial shape recognition by sub-matrix matching for partial matching guided image labeling
(Elsevier, 2005-10)We propose a new partial shape recognition algorithm by sub-matrix matching using a proximity-based shape representation. Given one or more example object templates and a number of candidate object regions in an image, ... -
The Pem homeobox gene: rapid evolution of the homeodomain, X chromosomal localization, and expression in reproductive tissue
(Elsevier: Genomics, 1996-06-15)A hallmark of homeobox genes is their high degree of sequence conservation in distantly related species. Here, we report the chromosomal localization, sequence, and expression pattern of an orphan homeobox gene,Pem,that ... -
Performance of a novel anisotropic conductive adhesive under thermal and temperature/humidity aging conditions

Period three limit-cycles in injected semiconductor lasers
(Institute of Physics Publishing, 2002-02)Experiments showing period three intensity oscillations are reported for a semiconductor laser subject to external injection. These oscillations appear close to a period doubling bifurcation of the fundamental laser ... -
Period-doubling cascades and chaos in a semiconductor laser with optical injection
(American Physical Society, 1995-05)We characterize the nonlinear dynamics of a semiconductor laser subject to optical injection. The key characteristics of measured optical spectra are reproduced in calculations based on a single-mode model that includes ... -
Period-doubling route to chaos in a semiconductor laser subject to optical injection
(American Institute of Physics, 1994-06-27)Experimental measurements and a single-mode analysis of a quantum-well laser diode subject to strong optical injection are combined to demonstrate that the diode follows a period-doubling route to chaos. All laser parameters ... -
Periodic prime knots and topologically transitive flows on 3-manifolds
(Elsevier Science B.V., Amsterdam, 2006-02-01)Suppose that () is a nonsingular (fixed point free) C^1 flow on a smooth closed 3-dimensional manifold M with H2(M) = 0. Suppose that () has a dense orbit. We show that there exists an open dense set N µ M such that any ... -
Perspective: empirical generalization and the role of culture in new product development
(Blackwell Publishing, Ltd. The definitive version is available at http://www.blackwell-synergy.com, 2007-03)Empirical generalization continues to be a challenge in most applied fields that favor publication of original results. The purpose of this study was to report on a new product development exercise in one, controlled ... -
Phosphorus-31 NMR spectroscopy using a loop-gap resonator
(Elsevier: Journal of Magnetic Resonance, 1986-06-15)The loop-gap resonator provides a simple and convenient alternative for large volume probes that are now practical for applications to NMR spectroscopy. A 400 ml probe is described for use in a large-bore magnet which is ... -
