Poulter, Charles Dale | Prenyltransferase. Kinetic studies of the 1'-4 coupling reaction with avian liver enzyme. | Prenyltransferase catalyzes the sequential, irreversible 1'-4 condensation of isopentenyl-PP with dimethylallyl-PP and geranyl-PP to yield farnesyl-PP. A kinetic study shows substrate inhibition by isopentenyl-PP at concentrations above 0.7 microM when the concentration of geranyl-PP is 1.0 microM o... | Birds; Kinetics; Structure-Activity Relationship; Substrate Specificity | 1979-10-10 |

Clayton, Dale H. | Ecological basis of coevolutionary history | Macroevolutionary patterns are difficult to interpret because they are the product of a time scale so vast that deterministic and chance events are hard to distinguish. Although the macroevolutionary history of a group can be reconstructed from extant species, determining the ecological context in ... | | 2003 |

Clayton, Dale H.; Rogers, Alan R. | Genetic analysis of lice supports direct contact between modern and archaic humans | Parasites can be used as unique markers to investigate host evolutionary history, independent of host data. Here we show that modern human head lice, Pediculus humanus, are composed of two ancient lineages, whose origin predates modern Homo sapiens by an order of magnitude (ca. 1.18 million years). | Pediculus humanus; Head lice; Molecular phylogeny; Phthirus | 2004 |

Clayton, Dale H. | Biology, ecology, and evolution of chewing lice | Chewing lice are small, dorsoventrally compressed insects and are parasites of virtually all birds (Fig. 1) and some mammals (Fig. 2). Many chewing lice are host specific, being found on only a single species of host. All chewing lice are permanent ectoparasites and complete their entire life c... | Chewing lice | 2003 |

Poulter, Charles Dale | Farnesyl diphosphate synthetase: molecular cloning, sequence, and expression of an essential gene from Saccharomyces cerevisiae | Farnesyl diphosphate (FPP) synthetase is a key enzyme in isoprenoid biosynthesis which supplies C15 precursors for several classes of essential metabolites including sterols, dolichols, and ubiquinones. The structural gene for FPP synthetase was isolated on a 4.5-kilobase EcoRI genomic restriction f... | Genetics; Transferases; Dimethylallyltranstransferase/biosynthesis | 1989-11-15 |

Symko, Orest George | Energy conversion using thermoacoustic devices | Thermoacoustic engines offer the possibility for simple and efficient energy convmiondevices. They can be prime movers where heat produces sound or heat pumps and refrigerators where sound pump heat.

Lawton, Kristy J. | Motor neurons tune premotor activity in a vertebrate central pattern generator | Central patterns generators (CPGs) are neural circuits that drive rhythmic motor output without sensory feedback. Vertebrate CPGs are generally believed to operate in a top-down manner in which premotor interneurons activate motor neurons that in turn drive muscles. In contrast, the frog (Xenopus la... | CPG; feed back; synchrony; vocal; vocalization; Xenopus | 2017 |

Sekercioglu, Cagan | Chewing lice (Phthiraptera) species found on Turkish shorebirds (Charadriiformes) | Approximately 4.500 species of lice have been so far described, with about 4.000 species seen on birds and with 3.000 species in the suborder Ischnocera 1. There are 465 bird species so far recorded in Turkey and the actual total is likely to exceed 500 species. However, the chewing lice fauna of th... | | 2010-01-01 |

Golden, Kenneth M. | Arbitrarily slow approach to limiting behavior | ABSTRACT. Let f(k, t): RN x [0, oo) -- R be jointly continuous in k and t, with lim(t)--(oo) f(k, t) = F(k) discontinuous for a dense set of k's. It is proven that there exists a dense set T of k's such that, for k e T , |f(k, t) - F(k)| approaches 0 arbitrarily slowly, i.e., roughly speaking, more ... | Random; Conductivity; Diffusion | 1991 |

Clayton, Dale H. | Experimental test of the importance of preen oil in Rock Doves (Columba livia) | Most species of birds have a uropygial gland, also known as a preen gland, which produces oil that birds spread through their plumage when preening. The plumage of waterfowl deprived of uropygial oil becomes brittle and is subject to breakage. | Columba livia; Columbiformes; Preen oil; Ectoparasites; Columbicola columbae; Campanulotes compare; Plumage | 2003 |

Golden, Kenneth M. | Classical transport in quasiperiodic media | Abstract. Classical transport coefficients such as the effective conductivity or diffusivity of a quasiperiodic medium were observed [1] to depend discontinuously on the frequencies of the quasiperiodicity. For example, for a one-dimensional medium with a potential V(x) = cosx + coskx , the effecti... | Transport; Diffusion; Random | 1991 |
