Khan, Faisal Habib | On the design of efficient magnetic coils for the stimulation of peripheral nerves | Neural stimulators are the key building blocks of current neuroprosthetic systems, such as cochlear and retinal implants. Due to direct current injections and foreign body reactions, conventional current passing electrodes suffer from reduced performance and reduced lifetimes. However, magnetic fiel... | 2013-01-01 | |

Hawkes, Kristen | On life history evolution (a comment on Chisholm) | Chisholm (CA 34:I-24) is right that the theory, models, and data of evolutionary biology apply to questions asked by social scientists. Work in life-history theory (Stearns 1992, Roff 1992, Charnov 1993) has especially provocative implications for the understanding of human development (see review i... | 1994-01-01 | |

Hawkes, Kristen | On optimal foraging models and subsistence transitions | Layton, Foley, and Williams are right: "progress" doesn't explain transitions from hunting and gathering to agriculture, by theory and models from behavioral ecology might. | 1992-01-01 | |

Bohs, Lynn A. | Phylogeny of the carolinense clade of solanum (Solanaceae) inferred from nuclear and plastid DNA sequences | The large and economically important genus Solanum contains ca. 1,400 species distributed worldwide. One of the 12-14 major clades identified in the genus is the Leptostemonum clade, or the "spiny solanums." Previous molecular phylogenetic studies have identified 14 major clades in the spiny solanum... | 2014-01-01 | |

Vardeny, Zeev Valentine | Photoexcitation dynamics in polythiophene/fullerene blends for photovoltaic applications | We used the transient and steady state photomodulation spectroscopies for studying the photoexcitations dynamics in blends of regio-regular poly(3-hexylthiophene) (RR-P3HT) and fullerene in a broad spectral range from 0.15 to 2.25 eV. We found that both localized polarons and singlet excitons are in... | 2012-01-01 | |

Kuhlman, Brian | PHD Entrepreneur | The idea for this speech began when my friends and family started asking what I would do after graduating with my PhD in psychology. Folks tended to get a bit confused when I replied that my plan is to start a business. You don't need a PhD to do that! It's true. The path leading from PhD to Entrepr... | entrepreneur; PhD; doctoral; industry; academia | 2013-05-03 |

Khan, Faisal Habib | PV faults: Overview, modeling, prevention and detection techniques | Recent PV faults and subsequent fire-hazards on April 5, 2009, in Bakersfield, California, and April 16, 2011, in Mount Holly, North Carolina provide evidence of a lack of knowledge among PV system manufacturers and installers about different PV faults. The conducted survey within the scope of this ... | 2013-01-01 | |
