    We investigated various photoprotection system combinations to find the combination that optimally extended the photobleach lifetime of a Cy3/Cy5 smFRET pair attached to a DNA hairpin in a single-molecule environment. We ...
  • Photoluminescence sidebands of carbon nanotubes below the bright singlet excitonic levels 

    Murakami, Yoichi; Lu, Benjamin; Kazaoui, Said; Minami, Nobutsugu; Okubo, Tatsuya; Maruyama, Shigeo (2009)
    We performed detailed photoluminescence (PL) spectroscopy studies of three different types of single-walled carbon nanotubes (SWNTs) by using samples that contain essentially only one chiral type of SWNT, (6,5), (7,5), or ...
  • Photothermal energy conversion by plasmonic nanoparticles 

    Cole, Joseph Raymond (2009)
    Photothermal energy conversion is important when designing optically active devices based on plasmonic nanoparticles. Many early applications of these nanoparticles, like photothermal tumor ablation, drug delivery, and ...
  • Physical Layer Algorithm and Hardware Verification of MIMO Relays Using Cooperative Partial Detection 

    Amiri, Kiarash; Wu, Michael; Duarte, Melissa; Cavallaro, Joseph R. (2010-03-01)
    Cooperative communication with multi-antenna relays can significantly increase the reliability and speed. However, cooperative MIMO detection would impose considerable complexity overhead onto the relay if a full ...
  • Physical layer algorithms with limited feedback: Power control and coding strategies 

    Khoshnevis, Ahmad (2007)
    The uncertainty in the received signal is the main limiting factor for the throughput of any communication system with limited resources. In this thesis we analyze the potential gain in throughput by managing channel ...
  • Physical model of the immune response of bacteria against bacteriophage through the adaptive CRISPR-Cas immune system 

    Han, Pu; Niestemski, Liang Ren; Barrick, Jeffrey E.; Deem, Michael W. (2013)
    Bacteria and archaea have evolved an adaptive, heritable immune system that recognizes and protects against viruses or plasmids. This system, known as the CRISPR-Cas system, allows the host to recognize and incorporate ...
  • The physics of eukaryotic chemotaxis 

    Levine, Herbert; Rappel, Wouter-Jan (2013)
    A small scratch on the skin can be quite painful. Fortunately, the pain is transitory and dissipates quickly once the wound heals. The healing process is facilitated by neutrophils, a type of white blood cell that removes ...
  • Pipelining Multiple SVDs On A Single Processor Array 

    Kota, Kishore; Cavallaro, Joseph R. (1994-07-20)
    We present a new family of architectures for processor arrays to implement Jacobi SVD which allow systolic loading and unloading of input and result matrices. Unlike most of the previous SVD arrays in the literature, our ...
