  • Schujman, Gustavo E; Paoletti, Luciana; de Mendoza, Diego; Grossman, Alan D. (2003-05)
    Bacterial cells exert exquisite control over the biosynthesis of their membrane lipids, but the mechanisms are obscure. We describe the identification and purification from Bacillus subtilis of a transcription factor, FapR, ...
  • Milewski, Paul A.; Galeano-Rios, Carlos A.; Nachbin, André; Bush, John W. M. (Cambridge University Press, 2015-07)
    A millimetric droplet bouncing on the surface of a vibrating fluid bath can self-propel by virtue of a resonant interaction with its own wave field. This system represents the first known example of a pilot-wave system of ...
  • Marsland, Robert Alvin; England, Jeremy L. (American Physical Society, 2015-11)
    A long-standing goal of nonequilibrium statistical mechanics has been to extend the conceptual power of the Boltzmann distribution to driven systems. We report some new progress towards this goal. Instead of writing the ...
  • Chesler, Paul; Lekaveckas, Mindaugas; Rajagopal, Krishna (Elsevier, 2013-05)
    We study the energy loss of a heavy quark propagating through the matter produced in the collision of two sheets of energy [P. M. Chesler and L. G. Yaffe, Phys. Rev. Lett. 106, 021601 (2011) [arXiv:1011.3562 [hep-th]].]. ...
  • Yeung, Kitty Y. M.; Chee, Jingyee; Yoon, Hosang; Song, Yi; Kong, Jing; Ham, Donhee (American Chemical Society (ACS), 2014-03)
    We introduce far-infrared graphene plasmonic crystals. Periodic structural perturbation—in a proof-of-concept form of hexagonal lattice of apertures—of a continuous graphene medium alters delocalized plasmonic dynamics, ...
  • Vatansever, Fatma; Hamblin, Michael R (Walter de Gruyter, 2012-10)
    Far infrared (FIR) radiation (λ=3–100 μm) is a subdivision of the electromagnetic spectrum that has been investigated for biological effects. The goal of this review is to cover the use of a further sub-division (3–12 μm) ...
  • Becla, Piotr; Feng, Zhe Chuan; Tien, Der-Chi; Yang, Yu-Chang; Hou, Fu-Chung; Shih, Yen-Hao; Jhang, Sheng-Hong; Yang, Tzuen-Rong (The International Society for Optical Engineering, 2009-09)
    Far-infrared (FIR) reflectance spectroscopy has been employed to study the optical properties for a series of bulk CdZnxTe1-x and CdSexTe1-x wafers. The zone-centre optical phonons for the ternary alloys show a variety of ...
  • Khan, Mustafa; Georgiou, John; Luyben, Thomas T.; Roder, John C.; Okamoto, Kenichi; Rivera Fuentes, Pablo Marcelo; Wrobel, Alexandra T.; Zastrow, Melissa L.; Lippard, Stephen J. (Royal Society of Chemistry, The, 2015-01)
    Imaging mobile zinc in acidic environments remains challenging because most small-molecule optical probes display pH-dependent fluorescence. Here we report a reaction-based sensor that detects mobile zinc unambiguously at ...
  • Tremblay, G. R.; O'Dea, C. P.; Baum, S. A.; Mittal, R.; Combes, F.; Li, Y.; McNamara, B. R.; Bremer, M. N.; Clarke, T. E.; Donahue, M.; Edge, A. C.; Fabian, A. C.; Hamer, S. L.; Hogan, M. T.; Oonk, J. B. R.; Quillen, A. C.; Sanders, J. S.; Salomé, P.; Voit, G. M.; McDonald, Michael A. (Oxford University Press, 2015-06)
    We present a multiwavelength morphological analysis of star-forming clouds and filaments in the central (≲50 kpc) regions of 16 low-redshift (z < 0.3) cool core brightest cluster galaxies. New Hubble Space Telescope imaging ...
  • Turitsyn, Konstantin; Kaplunovich, P. A. (Institute of Electrical and Electronics Engineers (IEEE), 2013-01)
    We present a novel selection algorithm for N-2 contingency analysis problem. The algorithm is based on the iterative bounding of line outage distribution factors and successive pruning of the set of contingency pair ...
  • Townsend, Alex John (Society for Industrial and Applied Mathematics, 2015-08)
    A fast and numerically stable algorithm is described for computing the discrete Hankel transform of order 0 as well as evaluating Schlömilch and Fourier--Bessel expansions in O(N(log N)[superscript 2]/loglog N) operations. ...
  • Wisdom, Jack; Hernandez, David Michael (Oxford University Press, 2015-09)
    We derive and present a fast and accurate solution of the initial value problem for Keplerian motion in universal variables that does not use the Stumpff series. We find that it performs better than methods based on the ...
  • Wrobel, Alexandra T.; Lippard, Stephen J.; Rivera-Fuentes, Pablo; Johnstone, Timothy; Liang, Alexandria D. (American Chemical Society (ACS), 2014-02)
    The first near-infrared fluorescent turn-on sensor for the detection of nitroxyl (HNO), the one-electron reduced form of nitric oxide (NO), is reported. The new copper-based probe, CuDHX1, contains a dihydroxanthene (DHX) ...
  • Ferreira, David; Armour, Kyle C.; Holland, Marika M.; Kostov, Yavor Krasimirov; Marshall, John C; Hausmann, Ute (Springer Berlin Heidelberg, 2016-05)
    We investigate how sea surface temperatures (SSTs) around Antarctica respond to the Southern Annular Mode (SAM) on multiple timescales. To that end we examine the relationship between SAM and SST within unperturbed ...
  • Karger, David R.; Levine, Matthew S. (Society for Industrial and Applied Mathematics, 2015-03)
    Consider an n-vertex, m-edge, undirected graph with integral capacities and max-flow value v. We give a new [~ over O](m + nv)-time maximum flow algorithm. After assigning certain special sampling probabilities to edges ...
  • Bodas, Shreeshankar; Shah, Devavrat (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    We are interested in the following question: given n numbers x[subscript 1], ..., x[subscript n], what sorts of approximation of average x[subscript ave] = 1overn (x[subscript 1] + ... + x[subscript n]) can be achieved by ...
  • Hu, Jingwei; Fomel, Sergey; Demanet, Laurent; Ying, Lexing (Society of Exploration Geophysicists, 2013-06)
    Generalized Radon transforms, such as the hyperbolic Radon transform, cannot be implemented as efficiently in the frequency domain as convolutions, thus limiting their use in seismic data processing. We have devised a fast ...
  • Uttamapinant, Chayasith; Tangpeerachaikul, Anupong; Grecian, Scott; Clarke, Scott M.; Singh, Upinder; Slade, Peter; Gee, Kyle R.; Ting, Alice Y. (Wiley Blackwell, 2012-05)
    Bring your own copper: Copper-chelating azides undergo much faster click reactions (CuAAC) than nonchelating azides under a variety of biocompatible conditions. This kinetic enhancement allows site-specific protein labeling ...
  • Yeh, Tom; Lee, John J.; Darrell, Trevor J. (Institute of Electrical and Electronics Engineers (IEEE), 2009-08)
    Object localization and recognition are important problems in computer vision. However, in many applications, exhaustive search over all object models and image locations is computationally prohibitive. While several methods ...
