    • 3D Ultrastructure of the Cochlear Outer Hair Cell Lateral Wall Revealed By Electron Tomography 

      Triffo, William Jeffrey; Palsdottir, Hildur; Song, Junha; Morgan, David Gene; McDonald, Kent L.; (2019)
      Outer Hair Cells (OHCs) in the mammalian cochlea display a unique type of voltage-induced mechanical movement termed electromotility, which amplifies auditory signals and contributes to the sensitivity and frequency selectivity of mammalian hearing. Electromotility occurs in the OHC lateral wall, but it is not fully understood how the supramolecular ...
    • 4 Ezra and 2 Baruch: Literary Composition and Oral Performance in First-Century Apocalyptic Literature 

      Henze, Matthias (2012)
      Students of 4 Ezra and 2 Baruch have long noticed numerous thematic, generic, and linguistic parallels that exist between them. Both texts were written in the late first or possibly the early second century C.E., most likely in the land of Israel. The composition of both works was triggered by the Roman destruction of Jerusalem in the year 70 C.E., ...
    • A Bayesian Integrative Model for Genetical Genomics with Spatially Informed Variable Selection 

      Cassese, Alberto; Guindani, Michele; Vannucci, Marina (2014)
      We consider a Bayesian hierarchical model for the integration of gene expression levels with comparative genomic hybridization (CGH) array measurements collected on the same subjects. The approach defines a measurement error model that relates the gene expression levels to latent copy number states. In turn, the latent states are related to the ...
    • A Burrowing/Tunneling Assay for Detection of Hypoxia in Drosophila melanogaster Larvae 

      Qiang, Karen M.; Zhou, Fanli; Beckingham, Kathleen M. (2018)
      Oxygen deprivation in animals can result from exposure to low atmospheric oxygen levels or from internal tissue damage that interferes with oxygen distribution. It is also possible that aberrant behavior of oxygen-sensing neurons could induce hypoxia-like behavior in the presence of normal oxygen levels. In D. melanogaster, development at low oxygen ...
