  • Cho, Yigil; Shin, Joong-Ho; Costa, Avelino; Kim, Tae Ann; Kunin, Valentin; Li, Ju; Lee, Su Yeon; Yang, Shu; Han, Heung Nam; Choi, In-Suk; Srolovitz, David J. (National Academy of Sciences (U.S.), 2014-12)
    In this paper we discuss the transformation of a sheet of material into a wide range of desired shapes and patterns by introducing a set of simple cuts in a multilevel hierarchy with different motifs. Each choice of ...
  • Lee, Seung-Kon; Jensen, Klavs F.; Sebastian Cabeza, Victor (Royal Society of Chemistry, 2014-09)
    Compared to freestanding nanoparticles, supported nanostructures typically show better mechanical stability as well as ease of handling. Unique shapes such as core–shells, raspberries and crescents have been developed on ...
  • Wu, Jiang; Griffeth, Nancy; Newport, Calvin Charles; Lynch, Nancy Ann (2011-08)
    The VNLayer approach simplifies software development for MANET by providing the developers an abstraction of a network divided into fixed geographical regions, each containing a virtual server for network services. In this ...
  • Desai, Tasha A.; Rodionov, Dmitry A.; Gefland, Mikhail S.; Alm, Eric J.; Rao, Christopher V. (Oxford University Press, 2009-03)
    The transcriptional program for a gene consists of the promoter necessary for recruiting RNA polymerase along with neighboring operator sites that bind different activators and repressors. From a synthetic biology perspective, ...
  • Kurosawa, Kazuhiko; Wewetzer, Sandra J.; Sinskey, Anthony J. (BioMed Central Ltd., 2013-09)
    Background: There has been a great deal of interest in fuel productions from lignocellulosic biomass to minimize the conflict between food and fuel use. The bioconversion of xylose, which is the second most abundant sugar ...
  • Hori, Yuki; Stern, Patrick; Hynes, Richard O.; Irvine, Darrell J. (Elsevier B.V., 2009-12)
    Local immunotherapies are under investigation for the treatment of unresectable tumors and sites of solid tumor resection to prevent local recurrence. Successful local therapy could also theoretically elicit systemic immune ...
  • Hsu, Wei-Chun; Chen, Gang; Weinstein, Lee Adragon; Yerci, Selcuk; Boriskina, Svetlana V. (IOP Publishing, 2015-04)
    We show via numerical simulations that the absorption and solar energy conversion efficiency of a thin-film photovoltaic (PV) cell can be significantly enhanced by embedding it into an optical cavity. A reflective ...
  • Kim, Minkyu; Huang, Aaron; Kang, Jeon Woong; Suthiwangcharoen, Nisaraporn; Nagarajan, Ramanathan; Olsen, Bradley D.; Gkikas, Emmanouil (Royal Society of Chemistry, 2014-02)
    A simple approach to enhancing the activity and stability of organophosphorus hydrolase (OPH) is developed based on interactions between the hydrophobic poly(propylene oxide) (PPO) block of amphiphilic Pluronics and the ...
  • Stolyarov, Alexander Mark; Gumennik, Alexander; McDaniel, William; Shapira, Ofer; Schell, Brent; Sorin, Fabien; Kuriki, Ken; Benoit, Giles; Rose, Aimee; Joannopoulos, John D.; Fink, Yoel (Optical Society of America, 2012-05)
    We demonstrate an in-fiber gas phase chemical detection architecture in which a chemiluminescent (CL) reaction is spatially and spectrally matched to the core modes of hollow photonic bandgap (PBG) fibers in order to enhance ...
  • Conway, Anne E.; Van Nostrand, Eric L.; Pratt, Gabriel A.; Aigner, Stefan; Wilbert, Melissa L.; Sundararaman, Balaji; Lambert, Nicole J.; Sathe, Shashank; Liang, Tiffany Y.; Essex, Anthony; Landais, Severine; Burge, Christopher B.; Jones, D. Leanne; Yeo, Gene W.; Freese, Peter Dale; Lambert, Nicole J.; Burge, Christopher B. (Elsevier, 2016-04)
    Human pluripotent stem cells (hPSCs) require precise control of post-transcriptional RNA networks to maintain proliferation and survival. Using enhanced UV crosslinking and immunoprecipitation (eCLIP), we identify RNA ...
  • Emori, Satoru; Beach, Geoffrey Stephen (American Institute of Physics (AIP), 2011-03)
    The effect of perpendicular magnetic anisotropy (PMA) on current-induced domain wall (DW) motion is investigated by micromagnetic simulations. The critical current density J[subscript C] to drive DWs into periodic ...
  • Sen, Yi-Heng; Jain, Tarun Kumar; Aguilar, Carlos A.; Karnik, Rohit (Royal Society of Chemistry, The, 2012-02)
    Nanofluidic sensing elements have been the focus of recent experiments for numerous applications ranging from nucleic acid fragment sizing to single-molecule DNA sequencing. These applications critically rely on high ...
  • Stocker, Roman; King, King Yeung; Peacock, Thomas; Torres, Carlos R. (Cambridge University Press, 2009-07)
    We present a combined experimental and numerical investigation of a sphere settling in a linearly stratified fluid at small Reynolds numbers. Using time-lapse photography and numerical modelling, we observed and quantified ...
  • Carlyle, Wenda C.; McClain, James B.; Tzafriri, Abraham R.; Bailey, Lynn; Zani, Brett G.; Markham, Peter M.; Stanley, James R.L.; Edelman, Elazer R. (Elsevier, 2012-07)
    Current drug eluting stent (DES) technology is not optimized with regard to the pharmacokinetics of drug delivery. A novel, absorbable-coating sirolimus-eluting stent (AC-SES) was evaluated for its capacity to deliver drug ...
  • Du, Ning; Doyle, Patrick S.; Renner, C. Benjamin (American Institute of Physics (AIP), 2014-05)
    We experimentally demonstrate that addition of small, charge-neutral polymers to a buffer solution can promote compression of dilute solutions of single electrophoresing DNA. This phenomenon contrasts with the observed ...
  • Reusswig, Philip David; Congreve, Daniel Norbert; Thompson, Nicholas J.; Baldo, Marc A. (American Institute of Physics (AIP), 2012-09)
    We demonstrate bilayer organic photovoltaic cells that incorporate a singlet exciton fission sensitizer layer to increase the external quantum efficiency (EQE). This solar cell architecture is realized by pairing the singlet ...
