Mishchenko, Eugene | Generation of spin current by Coulomb drag | Coulomb drag between two quantum wires is exponentially sensitive to the mismatch of their electronic densities. The application of a magnetic field can compensate this mismatch for electrons of opposite spin directions in different wires. The resulting enhanced momentum transfer leads to the conv... | Spin current; Coulomb drag; Quantum wires | 2006-12 |

Ogburn, Joyce L. | Acquiring minds want to know: is full text half full or half empty? | Fulltext has become a more prevalent offering in electronic resources. In some cases the original publisher may produce material both in print and electronic form or in electronic form only, while maintaining control over the contents. In other cases, another party may obtain the rights from the pu... | Full text; Digital libraries; Electronic information | 1996 |

Bastiani, Michael | Guidance of neuronal growth cones in the grasshopper embryo. III. Recognition of specific glial pathways | In the previous 2 papers, we focused on the selective affinities that growth cones display for specific axonal pathways. Little is known, however, about how this orthogonal scaffold of axonal pathways in the CNS is established in the first place, and what, if any, role glia might play in these even... | CNS; Nerve; Cells | 1986 |
