  • Marzouk, Youssef M.; Najm, Habib N. (Elsevier, 2008-12)
    We consider a Bayesian approach to nonlinear inverse problems in which the unknown quantity is a spatial or temporal field, endowed with a hierarchical Gaussian process prior. Computational challenges in this construction ...
  • Ohlberger, Mario; Smetana, Kathrin (Society for Industrial and Applied Mathematics, 2014-04)
    In this article we introduce a new dimensional reduction approach which is based on the application of reduced basis (RB) techniques in the hierarchical model reduction (HMR) framework. Considering problems that exhibit a ...
  • Ondrus, Alison E.; Kaniskan, Husnu Umit; Movassaghi, Mohammad (Elsevier B.V., 2010-04)
    The union of functionalized pyrroloindolizines for the synthesis of heterodimeric products relevant to myrmicarin alkaloids is described. Design and synthesis of tricyclic substrates and new methods for their union enable ...
  • Gomez-Uribe, Phillip M.; Mueller, Melissa A.; Gleichman, Julia S.; Kramer, Matthew D.; Wang, Qi; Sibrian-Vazquez, Martha; Strongin, Robert M.; Steyger, Peter S.; Cotanche, Douglas Allen; Matsui, Jonathan I. (Public Library of Science, 2013-02)
    Inner ear sensory hair cells die following exposure to aminoglycoside antibiotics or chemotherapeutics like cisplatin, leading to permanent auditory and/or balance deficits in humans. Zebrafish (Danio rerio) are used to ...
  • Jarosz, Daniel F.; Cohen, Susan E.; Delaney, James C.; Essigmann, John M.; Walker, Graham C. (National Academy of Sciences (U.S.), 2009-12)
    The only Y-family DNA polymerase conserved among all domains of life, DinB and its mammalian ortholog pol κ, catalyzes proficient bypass of damaged DNA in translesion synthesis (TLS). Y-family DNA polymerases, including ...

  • San Antonio, James D.; Schweitzer, Mary H.; Jensen, Shane T.; Kalluri, Raghu; Buckley, Michael; Orgel, Joseph P. R. O. (Public Library of Science, 2011-06)
    Eleven collagen peptide sequences recovered from chemical extracts of dinosaur bones were mapped onto molecular models of the vertebrate collagen fibril derived from extant taxa. The dinosaur peptides localized to fibril ...
  • Zapata, Luis E.; Miller, Daniel E.; Ripin, Daniel J.; Fan, Tso Yee (SPIE, 2010-03)
    A cryogenically cooled Yb:YLF laser with 224-W output power at 995 nm, linearly polarized along the c-axis, has been demonstrated, and laser oscillation has also been obtained polarized along the a-axis. The beam quality ...
  • Li, Duo; Demirbas, Umit; Birge, Jonathan R.; Petrich, Gale S.; Kolodziejski, Leslie A.; Sennaroglu, Alphan; Kärtner, Franz X.; Fujimoto, James G. (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    We report a low-cost, 1 GHz repetition-rate, diode-pumped, saturable Bragg reflectors mode-locked Cr:LiSAF laser, which generates nearly transform-limited 103-fs long pulses around 866 nm, with a record high peak power of 1.45 kW.
  • Tinberg, Christine E.; Lippard, Stephen J. (American Chemical Society, 2011-03)
    The controlled oxidation of methane to methanol is a chemical transformation of great value, particularly in the pursuit of alternative fuels, but the reaction remains underutilized industrially because of inefficient and ...
  • Lin, J.; Bayro, M.J.; Khaneja, N.; Griffin, Robert Guy (Elsevier, 2008-12)
    We describe some new developments in the methodology of making heteronuclear and homonuclear recoupling experiments in solid state NMR insensitive to rf-inhomogeneity by phase alternating the irradiation on the spin system ...
  • Burbano, Mario; Marrocchelli, Dario; Yildiz, Bilge; Norberg, Stefan T; Hull, Stephen; Madden, Paul A; Watson, Graeme W; Tuller, Harry L. (IOP Publishing, 2011-06)
    In this paper we present the parameterization of a new interionic potential for stoichiometric, reduced and doped CeO[subscript 2]. We use a dipole polarizable potential (DIPPIM: the dipole polarizable ion model) and ...
  • Green, Jeremy Russell; Engelhardt, Michael; Negele, John W.; Varilly, Patrick (American Institute of Physics, 2011-07)
    Using lattice QCD, a diquark can be studied in a gauge-invariant manner by binding it to a static quark in a heavylight-light hadron. We compute the simultaneous two-quark density of a diquark, including corrections for ...
  • Leithinger, Daniel; Lakatos, David; DeVincenzi, Anthony; Blackshaw, Matthew; Ishii, Hiroshi (Association for Computing Machinery (ACM), 2011-10)
    Actuated shape output provides novel opportunities for experiencing, creating and manipulating 3D content in the physical world. While various shape displays have been proposed, a common approach utilizes an array of linear ...
  • Hsu, Wei-Chun; Tong, Jonathan K.; Liao, Bolin; Burg, Brian R.; Chen, Gang (American Institute of Physics, 2013-02)
    A measurement platform is introduced that combines a bilayer cantilever probe with a Fourier transform infrared spectrometer to measure absolute spectral absorptance between wavelengths of 3 μm and 18 μm directly and ...
  • Braunstein, Samuel L.; Garcia-Patron Sanchez, Raul; Lloyd, Seth; Pirandola, Stefano (American Physical Society, 2009-02)
    We define the direct and reverse secret-key capacities of a memoryless quantum channel as the optimal rates that entanglement-based quantum-key-distribution protocols can reach by using a single forward classical communication ...
  • Goldfless, Stephen Jacob; Belmont, Brian Joshua; de Paz, Alexandra M.; Niles, Jacquin (Oxford University Press (OUP), 2012-01)
    Sequence-specific RNA–protein interactions, though commonly used in biological systems to regulate translation, are challenging to selectively modulate. Here, we demonstrate the use of a chemically-inducible RNA–protein ...
  • Sen, Dipanjan; Cohen, Alan; Thompson, Aidan P.; Goddard, William A., III; Buehler, Markus J. (Cambridge University Press, 2010-01)
    Silicon is an important material not only for semiconductor applications, but also for the development of novel bioinspired and biomimicking materials and structures or drug delivery systems in the context of nanomedicine. ...
  • Han, Zhaohong; Cai, Yan; Kimerling, Lionel C.; Michel, Jurgen; Camacho-Aguilera, Rodolfo Ernesto (American Institute of Physics (AIP), 2013-04)
    Direct band gap narrowing in highly doped n-type Ge is observed through photoluminescence measurements by determining the spectrum peak shift. A linear relationship between the direct band gap emission and carrier concentration ...
  • Bauer, Gerry P.; Choudalakis, Georgios; Gomez-Ceballos, Guillelmo; Hahn, Kristian Allan; Henderson, C.; Knuteson, Bruce O.; Makhoul, K.; Paus, Christoph M. E.; Xie, Si (American Physical Society, 2009-01)
