Liu, Feng | Magnetism and local order: ab initio tight-binding theory | The effects of the local environment on the electronic structure and magnetic moments of Fe, Co, and Ni have been studied by confining these atoms to assume various structural forms such as chains, surfaces, layers, and crystals. The coordination number of the atoms can thus be changed over a wide r... | Local order; Ab-initio tight-binding theory; Magnetic moment; Electronic structure; Fe; Co; Ni | 1989-04 |

Gesteland, Raymond F. | Characterization of lysozyme messenger and lysozyme synthesized in vitro | In vitro systems for protein systhesis have been in wide use for about 10 years. In most of the early work protein synthesis was measured by following the incorporation of radioactive amino acids into acid precipitable material.

Liu, Feng | Magnetism in small vanadium clusters | Using the self-consistent-field molecular-orbital theory and the density-functional approximation, we show that vanadium could become magnetic if its size and dimension were constrained. This is illustrated for vanadium forming clusters with body-centered-cubic (bcc) geometry as well as for linear c... | Vanadium clusters; Molecular-orbital theory; Density-functional approximation; Stoner criterion | 1991-04 |

Angelucci, Alessandra; Lund, Jennifer S. | Circuits for local and global signal integration in primary visual cortex | Contrast-dependent changes in spatial summation and contextual modulation of primary visual cortex (V1) neuron responses to stimulation of their receptive field reveal long-distance integration of visual signals within V1, well beyond the classical receptive field (cRF) of single neurons.

Riloff, Ellen M. | Toward completeness in concept extraction and classification | Many algorithms extract terms from text together with some kind of taxonomic classification (is-a) link. However, the general approaches used today, and specifically the methods of evaluating results, exhibit serious shortcomings.
