  • Datta, Soumendu; Kabir, Mohammad Mukul; Mookerjee, Abhijit; Saha-Dasgupta, Tanusri (American Physical Society, 2011-02)
    With a goal to produce a giant magnetic moment in a Mn13 cluster that will be useful for practical applications, we have considered the structure and magnetic properties of a pure Mn13 cluster and substitutionally doped ...
  • Wu, Jiang; Griffeth, Nancy; Newport, Calvin; Lynch, Nancy (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 ...
  • 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 ...
  • 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 N. (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 ...
  • 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 ...
  • Ng, Chee Ping; Mohamed Sharif, Abdul Rahim; Heath, Daniel E.; Chow, John W.; Zhang, Claire BY.; Chan-Park, Mary B.; Hammond, Paula T.; Chan, Jerry KY.; Griffith, Linda G. (Elsevier, 2014-02)
    Large-scale expansion of highly functional adult human mesenchymal stem cells (aMSCs) remains technologically challenging as aMSCs lose self renewal capacity and multipotency during traditional long-term culture and their ...
  • Chléirigh, C. Ni; Gomez, Leonardo; Hashemi, Pouya; Hoyt, Judy L. (Institute of Electrical and Electronics Engineers (IEEE), 2010-06)
    The hole mobility characteristics of 〈110〉 /(100)-oriented asymmetrically strained-SiGe p-MOSFETs are studied. Uniaxial mechanical strain is applied to biaxial compressive strained devices and the relative change in ...
  • Gomez, Leonardo; Hashemi, Pouya; Hoyt, Judy L. (Institute of Electrical and Electronics Engineers, 2009-10)
    Hole mobility and velocity are extracted from scaled strained-Si[subscript 0.4]5Ge[subscript 0.55]channel p-MOSFETs on insulator. Devices have been fabricated with sub-100-nm gate lengths, demonstrating hole mobility and ...
  • Carr, Peter A., Sr.; Wang, Harris H.; Sterling, Bram Henry; Isaacs, Farren J.; Lajoie, Marc J.; Xu, George Jing; Church, George M.; Jacobson, Joseph (Oxford University Press (OUP), 2012-05)
    Genome-scale engineering of living organisms requires precise and economical methods to efficiently modify many loci within chromosomes. One such example is the directed integration of chemically synthesized single-stranded ...
  • Shiue, Ren-Jye; Gan, Xuetao; Gao, Yuanda; Li, Luozhou; Yao, Xinwen; Szep, Attila; Walker, Dennis; Hone, James; Englund, Dirk Robert (American Institute of Physics (AIP), 2013-12)
    We demonstrate the controlled enhancement of photoresponsivity in a graphene photodetector by coupling to slow light modes in a long photonic crystal linear defect cavity. Near the Brillouin zone (BZ) boundary, spectral ...
  • Lloyd, Seth; Lupo, Cosmo; Giovannetti, Vittorio; Pirandola, Stefano; Mancini, Stefano (American Physical Society, 2011-07)
    We consider the problem of quantum communication mediated by a passive optical refocusing system. The model captures the basic features of all those situations in which a signal is either refocused by a repeater for ...
  • Cappellaro, Paola; Pham, L. M.; Bar-Gill, N.; Belthangady, C.; Sage, D. Le; Lukin, M. D.; Yacoby, A.; Walsworth, R. L. (American Physical Society, 2012-07)
    We use multipulse dynamical decoupling to increase the coherence lifetime (T[subscript 2]) of large numbers of nitrogen-vacancy (NV) electronic spins in room temperature diamond, thus enabling scalable applications of ...
  • Zhao, Xiaoyong; Poon, Zhiyong; Engler, Amanda C.; Bonner, Daniel K.; Hammond, Paula T. (American Chemical Society, 2012-05)
    One of the major obstacles that delay the clinical translation of polymeric micelle drug delivery systems is whether these self-assembled micelles can retain their integrity in blood following intravenous (IV) injection. ...
