Armentrout, Peter B. | Kinetic-energy dependence of competitive spin-allowed and spin-forbidden reactions: V++CS2 | The kinetic-energy dependence of the V++CS2 reaction is examined using guided ion-beam mass spectrometry. Several different ion sources are used to systematically vary the V+ electronic state distributions and elucidate the reactivities of both the ground and excited state V+ cation. | Carbon disulfide; Vanadium ions; Transition metal ions; Bond energies; Endothermic reactions; Exothermic reactions | 1999 |

Riloff, Ellen M. | Learning dictionaries for information extraction by multi-level bootstrapping | Information extraction systems usually require two dictionaries: a semantic lexicon and a dictionary of extraction patterns for the domain. We present a multilevel bootstrapping algorithm that generates both the semantic lexicon and extraction patterns simultaneously. As input, our technique requir... | Information extraction; Extraction patterns; Multi-level bootstrapping; Learning dictionaries | 1999 |

Zhang, Lixin; Carter, John | Memory system support for image processing | Processor speeds are increasing rapidly, but memory speeds are not keeping pace. Image processing is an important application domain that is particularly impacted by this growing performance gap. Image processing algorithms tend to have poor memory locality because they access their data in a non-se... | Processor speeds; Memory system support; Memory speeds | 1999 |

Tiwari, Ashutosh | Metal-insulator transition in La0.7Sr0.3Mn1-xFexO3 | We report the effect of Fe doping at the Mn site in La0.7Sr0.3MnO3 oxides. We find that the doping of Fe does not cause any structural change, but the electrical transport in the system is strongly affected. The parent compound La0.7Sr0.3MnO3 shows a resistivity peak at T=Tp (365 K) and behaves as ... | Tunneling conductance; Perovskite manganates; Iron doping; Fe doping | 1999 |

Dailey, Andrew T. | Modulation of macrophage and microglial responses to axonal injury in the peripheral and central nervous systems | OBJECTIVE: After axonal injury, macrophages rapidly infiltrate and become activated in the mammalian peripheral nervous system (PNS) but not the central nervous system (CNS). We used the dorsal root pathway to study factors that modulate the response of macrophages to degenerating axons in both the ... | Axonal injury; Macrophage response; Microglial response; Peripheral nervous system; Lewis rats | 1999 |

Baehr, Wolfgang; Rao, Narayanam V. | Molecular characterization of a third member of the guanylyl cyclase-activating protein subfamily | The mammalian retina contains at least two guanylyl cyclases (GC1 and GC2) and two guanylyl cyclase-activating proteins (GCAP1 and GCAP2). Here we present evidence of the presence of a new photoreceptor-specific GCAP, termed GCAP3, which is closely related to GCAP1.
