 | 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 |

 | Stringfellow, Gerald B. | Order and surface processes in III-V semiconductor alloys | Semiconductor alloys have become increasingly useful during the last four decades because, through the use of alloys, the properties of semiconductors can be tailored by varying the composition to precisely match the requirements for specific electronic and photonic devices. | Semiconductor alloys; Transmission-electron-diffraction pattern; Organometallic Vaper-phase epitaxy | 1997 |

 | Stringfellow, Gerald B.; Zhu, Jing Yi; Liu, Feng | Dual-surfactant effect to enhance p-type doping in III-V semiconductor thin films | Surfactant effects are usually achieved by the addition of a single surface element.

 | Mattis, Daniel C. | Eigenfunction localization in dilute lattices of various dimensionalities | As a fraction of bonds p is removed from a lattice, we find a threshold PQ above which all eigenstates are nonpropagating (Anderson localized). This occurs well before the classical percolation threshold. For example, in two dimensions where the classical threshold is pc = 1/2 , we find PQ = 0. | Eigenstates; Dilute lattices | 1981-05 |
