  • Webb, Chris D; Teleman, Aurelio; Gordon, Scott; Straight, Aaron; Belmont, Andrew; Lin, Daniel Chi-Hong; Wright, Andrew; Losick, Richard; Grossman, Alan D. (Elsevier, 1997-03)
    To investigate chromosome segregation in B. subtilis, we introduced tandem copies of the lactose operon operator into the chromosome near the replication origin or terminus. We then visualized the position of the operator ...
  • Lichtscheidl, Alejandro G.; Ng, Victor Wee Lin; Takase, Michael K.; Malcolmson, Steven J.; Meek, Simon J.; Li, Bo; Kiesewetter, Elizabeth T.; Hoveyda, Amir H.; Muller, Peter; Schrock, Richard Royce (American Chemical Society (ACS), 2012-06)
    Seven bipyridine adducts of molybdenum imido alkylidene bispyrrolide complexes of the type Mo(NR)(CHCMe[subscript 2]R′)(Pyr)[subscript 2](bipy) (1a–1g; R = 2,6-i-Pr[subscript 2]C[subscript 6]H[subscript 3] (Ar), adamantyl ...
  • Berwick, Robert C.; Okanoya, Kazuo; Bolhuis, Johan J.; Beckers, Gabriel J. L. (Frontiers Research Foundation, 2012-04)
    Comparative studies of linguistic faculties in animals pose an evolutionary paradox: language involves certain perceptual and motor abilities, but it is not clear that this serves as more than an input–output channel for ...
  • Swager, Timothy Manning; Izuhara, Daisuke (Royal Society of Chemistry, 2011-01)
    Bispyridinium-phenylene-based conjugated donor–acceptor copolymers were synthesized by a Stille cross-coupling and cyclization sequence. These polyelectrolytes are freely soluble in organic solvents and display broad optical ...
  • Godzi, Maxim; Calderon, Abram; Stamatov, Rumen; Peterson, Laura; Zaytsev, Anatoly V.; Segura-Pena, Dario; Ballister, Edward R.; Mayo, Alyssa M.; Black, Ben E.; Ataullakhanov, Fazly I.; Lampson, Michael A.; Grishchuk, Ekaterina L. (eLife Sciences Publications, Ltd., 2016-01)
    Aurora B kinase, a key regulator of cell division, localizes to specific cellular locations, but the regulatory mechanisms responsible for phosphorylation of substrates located remotely from kinase enrichment sites are ...
  • Efremov, Artem K.; Cao, Jianshu (Elsevier, 2011-09)
    Cell adhesion plays a central role in multicellular organisms helping to maintain their integrity and homeostasis. This complex process involves many different types of adhesion proteins, and synergetic behavior of these ...
  • Moroz, Yurii S.; Cozzolino, Anthony Frank; Rybak-Akimova, Elena V.; Cummins, Christopher C. (International Union of Crystallography (IUCr), 2011-01)
    The title compound, [Mo[subscript 2](C[subscript 11]H[subscript 16]N)[subscript 4](C[subscript 10]H[subscript 11]N)[subscript 2]], is a dinuclear molybdenum complex with a formal metal-metal bond [Mo...Mo separation = ...
  • Gorantla, Siva K.; Zheng, Lizhong; Coleman, Todd P.; Nakiboglu, Baris (Institute of Electrical and Electronics Engineers (IEEE), 2013-02)
    The bit-wise unequal error protection problem, for the case when the number of groups of bits l is fixed, is considered for variable-length block codes with feedback. An encoding scheme based on fixed-length block codes ...
  • Brakerski, Zvika; Goldwasser, Shafi; Kalai, Yael Tauman (Springer Berlin / Heidelberg, 2011-03)
    We show how to achieve public-key encryption schemes that can securely encrypt nonlinear functions of their own secret key. Specifically, we show that for any constant d ∈ ℕ, there exists a public-key encryption scheme ...
  • Saraf, Shubhangi; Kayal, Neeraj (Institute of Electrical and Electronics Engineers, 2010-03)
    We study EIIE(k) circuits, i.e., depth three arithmetic circuits with top fanin k. We give the first deterministic polynomial time blackbox identity test for EIIE(k) circuits over the field Q of rational numbers, thus ...
  • Huang, J.; Adams, A.; Wang, Chien; Zhang, C. (European Geosciences Union / Copernicus, 2009-11)
    We have recently investigated large-scale co-variability between aerosol and precipitation and other meteorological variables in the West African Monsoon (WAM) region using long term satellite observations and reanalysis ...
  • Ghachem, Malick; James, Erica C. (American Historical Association, 2015-09)
    In the small town of Somers, Connecticut, near the Massachusetts border, the cofounder of a prominent American restaurant chain has built an apparently meticulous replica of Thomas Jefferson’s mansion in Monticello, Virginia. ...
  • Price, Richard H.; Khanna, Gaurav; Hughes, Scott A. (American Physical Society, 2013-11)
    Gravitational waves emitted during the inspiral, plunge and merger of a black hole binary carry linear momentum. This results in an astrophysically important recoil to the final merged black hole, a “kick” that can eject ...
  • Anous, Tarek; Hartman, Thomas; Rovai, Antonin; Sonner, Julian (Springer Berlin Heidelberg, 2016-07)
    We present a first-principles CFT calculation corresponding to the spherical collapse of a shell of matter in three dimensional quantum gravity. In field theory terms, we describe the equilibration process, from early times ...
  • Penna, Robert (American Physical Society, 2015-10)
    Black hole jet power depends on the angular velocity of magnetic field lines, Ω[subscript F]. Force-free black hole magnetospheres typically have Ω[subscript F]/Ω[subscript H] ≈ 0.5, where Ω[subscript H] is the angular ...
  • Simcoe, Robert A. (IOP Publishing, 2014-07)
    We present the analysis of optical and near-infrared spectra of the only four z > 6.5 quasars known to date, discovered in the UKIDSS-LAS and VISTA-VIKING surveys. Our data set consists of new Very Large Telescope/X-Shooter ...
  • Penna, Robert (American Physical Society, 2014-05)
    Spinning black holes tend to expel magnetic fields. In this way they are similar to superconductors. It has been a persistent concern that this black hole “Meissner effect” could quench jet power at high spins. This would ...
  • Penna, Robert (American Physical Society, 2014-08)
    Extremal black holes tend to expel magnetic and electric fields. Fields are unable to reach the horizon because the length of the black hole throat blows up in the extremal limit. The length of the throat is related to the ...
  • Nickel, Marcel Dominik Johannes; Kovtun, Pavel (American Physical Society, 2009-01)
    We describe black holes in d+3 dimensions, whose thermodynamic properties correspond to those of a scale-invariant nonrelativistic (d+1)-dimensional quantum system with a dynamical exponent z=2. The gravitational model ...
  • Nomura, Yasunori; Varela, Jaime; Weinberg, Sean J. (American Physical Society, 2013-04)
    A coarse-grained description for the formation and evaporation of a black hole is given within the framework of a unitary theory of quantum gravity preserving locality, without dropping the information that manifests as ...
