  • Optical reflectance assay for the detection of biofilm formation 

    Broschat, Shira L.; Loge, Frank J.; Peppin, Jason D.; White, David; Call, Douglas R.; Kuhn, Edward (Journal of Biomedical Optics, 2005-08)
    We describe the protocol for an inexpensive and nondestructive optical reflectance assay for the measurement of biofilm formation. Reflectance data are obtained using an Ocean Optics !Dunedin, Florida" USB 2000 spectrometer ...
  • Primary structural variation in Anaplasma marginale Msp2 efficiently generates immune escape variants 

    Graca, Telmo; Paradiso, Lydia; Broschat, Shira L.; Noh, Susan M.; Palmer, Guy H. (Infection and Immunity, 2015-11)
    Antigenic variation allows microbial pathogens to evade immune clearance and establish persistent infection. Anaplasma marginale utilizes gene conversion of a repertoire of silent msp2 alleles into a single active expression ...
  • The method of the local parabolic approximation for rough surface scattering 

    Ivanova, Kristink; Broschat, Shira L. (Journal of the Acoustical Society of America, 1993-10)
    A method for evaluation of scattering from rough surfaces which is similar to the Kirchhoff approximation is considered. However, it is based on a local parabolic approximation of the surface irregularities rather than a ...
  • The SSA+ for scattering from dielectric surfaces at very low grazing angles 

    Broschat, Shira L.; Wang, Yanqiu (Taylor and Francis, 2011-02)
    In this paper we develop an extension of the small slope approximation (SSA) for scattering from randomly rough Dirichlet surfaces, which includes some multiple scattering. This extension is designated by SSA+. We focus ...
  • Using protein clusters from whole proteomes to construct and augment a dendrogram 

    Zhou, Yunyun; Call, Douglas R.; Broschat, Shira L.; Van de Peer, Yves (Advances in Bioinformatics, 2013-01)
    In this paper we present a new ab initio approach for constructing an unrooted dendrogram using protein clusters, an approach that has the potential for estimating relationships among several thousands of species based on ...
  • Validation of mixed-genome microarrays as a method for genetic discrimination 

    Wan, Yan; Broschat, Shira L.; Call, Douglas R. (Applied and Environmental Microbiology, 2007-03)
    Comparative genomic hybridizations have been used to examine genetic relationships among bacteria. The microarrays used in these experiments may have open reading frames from one or more reference strains (whole-genome ...
  • Whole-proteome analysis of twelve species of Alphaproteobacteria links four pathogens 

    Zhou, Yunyun; Call, Douglas R.; Broschat, Shira L. (Pathogens, 2013-01)
    Thousands of whole-genome and whole-proteome sequences have been made available through advances in sequencing technology, and sequences of millions more organisms will become available in the coming years. This wealth of ...
