    • Laser-assisted metalorganic chemical vapor deposition of zinc selenide 

      Shinn, Gregory B. (1992)
      Laser-assisted metalorganic chemical vapor deposition (LMOCVD) has been used to grow epitaxial zinc selenide at temperatures as low as 200$\sp\circ$C. The metalorganic sources, dimethylzinc (DMZ) and diethylselenide (DESe), ...
    • Laser-assisted metalorganic chemical vapor deposition of zinc sulfide 

      Stokes, Scott Wilson (1997)
      Laser-assisted metalorganic chemical vapor deposition (MOCVD) was used to grow crystalline zinc sulfide at temperatures as low as 200$\sp\circ$C. The metalorganic sources, dimethylzinc and diethylsulfide, were photodissociated ...
    • Laser-induced porous graphene films from commercial polymers 

      Lin, Jian; Peng, Zhiwei; Liu, Yuanyue; Ruiz-Zepeda, Francisco; Ye, Ruquan; Samuel, Errol L.G.; Yacaman, Miguel Jose; Yakobson, Boris I.; Tour, James M. (2014)
      The cost effective synthesis and patterning of carbon nanomaterials is a challenge in electronic and energy storage devices. Here we report a one-step, scalable approach for producing and patterning porous graphene films ...
    • A Lateral Flow Assay for Quantitative Detection of Amplified HIV-1 RNA 

      Rohrman, Brittany A.; Leautaud, Veronica; Molyneux, Elizabeth; Richards-Kortum, Rebecca R. (2012)
      Although the accessibility of HIV treatment in developing nations has increased dramatically over the past decade, viral load testing to monitor the response of patients receiving therapy is often unavailable. Existing ...
    • Lattice Algorithms for Compression Color Space Estimation in JPEG Images 

      Neelamani, Ramesh; de Queiroz, Ricardo; Baraniuk, Richard G. (2001-08-01)
      JPEG (Joint Photographic Experts Group) is an international standard to compress and store digital color images [5]. Given a color image that was previously JPEG-compressed in some hidden color space, we aim to estimate ...
    • Lattice model of oligonucleotide hybridization in solution. II. Specificity and cooperativity 

      Araque, J.C.; Robert, M.A. (2016)
      Because oligonucleotides are short sequences of nucleic acid bases, their association in solution with complementary strands (hybridization) is often seen to conform to a simple two-state model. However, experimental ...
    • Layered Dynamic Fault Detection and Tolerance for Robots 

      Visinsky, Monica L.; Walker, Ian D.; Cavallaro, Joseph R. (1993-05-01)
      Fault tolerance is increasingly important for space and hazardous environment robotics. Robots need to quickly detect and tolerate internal failures in order to continue performing their tasks without the need for immediate ...
    • Lazy Release Consistency for Distributed Shared Memory
