  • Tan, Kelly R.; Turiault, Marc; Mirzabekov, Julie J.; Doehner, Jana; Deisseroth, Karl; Tye, Kay; Yvon, Cedric; Labouebe, Gwenael; Luscher, Christian (Elsevier, 2012-03)
    Salient but aversive stimuli inhibit the majority of dopamine (DA) neurons in the ventral tegmental area (VTA) and cause conditioned place aversion (CPA). The cellular mechanism underlying DA neuron inhibition has not been ...
  • Fuller, Adelaide M.; Cook, Elizabeth G.; Kelley, Kerry (Genetics Society of America, The, 2010-03)
    TAHRE, the least abundant of the three retrotransposons forming telomeres in Drosophila melanogaster, has high sequence similarity to the gag gene and untranslated regions of HeT-A, the most abundant telomere-specific ...
  • Thaler, Jesse; Waalewijn, Wouter J.; Larkoski, Andrew (Springer-Verlag, 2014-11)
    Discriminating quark jets from gluon jets is an important but challenging problem in jet substructure. In this paper, we use the concept of mutual information to illuminate the physics of quark/gluon tagging. Ideal quark/gluon ...
  • Hu, Qing; Reno, John L.; Burghoff, David Patrick; Chan, Chun Wang Ivan (American Institute of Physics (AIP), 2012-06)
    Using terahertz time-domain spectroscopy, the gain of scattering-assisted terahertz quantum cascade lasers is measured. By examining the intersubband gain and absorption over a wide range of bias voltages, we experimentally ...
  • Fan, Frank H.; Hall, Steven (American Helicopter Society International, Inc., 2014-05)
    This paper investigates the dynamics of the SMART rotor, and presents a method to design a gain-scheduled controller to reduce the harmonic vibration throughout the flight envelope. The dynamics of the SMART rotor was ...
  • Genel, Shy; Fall, S. Michael; Hernquist, Lars; Vogelsberger, Mark; Snyder, Gregory F.; Rodriguez-Gomez, Vicente; Sijacki, Debora; Springel, Volker (IOP Publishing, 2015-05)
    We study the stellar angular momentum of thousands of galaxies in the Illustris cosmological simulation, which captures gravitational and gas dynamics within galaxies, as well as feedback from stars and black holes. We ...
  • Fang, Taotao; Mckee, Christopher F.; Canizares, Claude R.; Wolfire, Mark (IOP Publishing, 2006-06)
    Recent Chandra and XMM-Newton observations of distant quasars have shown strong local (z ~ 0) X-ray absorption lines from highly ionized gas, primarily He-like oxygen. The nature of these X-ray absorbers, i.e., whether ...
  • Lopez, Laura A.; Ramirez-Ruiz, Enrico; Castro, Daniel; Pearson, Sarah (Institute of Physics/American Astronomical Society, 2013-02)
    We present results from a 220 ks observation of the Galactic supernova remnant (SNR) W49B using the Advanced CCD Imaging Spectrometer on board the Chanrda X-ray Observatory. We exploit these data to perform detailed spatially ...
  • Zehavi, Idit; Zheng, Zheng; Weinberg, David H.; Blanton, Michael R.; Bahcall, Neta A.; Berlind, Andreas A.; Brinkmann, Jon; Frieman, Joshua A.; Gunn, James E.; Lupton, Robert H.; Nichol, Robert C.; Percival, Will J.; Schneider, Donald P.; Skibba, Ramin A.; Strauss, Michael A.; Tegmark, Max Erik; York, Donald G. (Institute of Physics Publishing, 2011-07)
    We measure the luminosity and color dependence of galaxy clustering in the largest-ever galaxy redshift survey, the main galaxy sample of the Sloan Digital Sky Survey Seventh Data Release. We focus on the projected correlation ...
  • Romero, Charles E.; Mason, Brian S.; Sayers, Jack; Mroczkowski, Tony; Sarazin, Craig; Donahue, Megan; Baldi, Alessandro; Clarke, Tracy E.; Sievers, Jonathan; Dicker, Simon R.; Reese, Erik D.; Czakon, Nicole; Devlin, Mark; Korngut, Phillip M.; Golwala, Sunil; Young, Alexander H. (IOP Publishing, 2017-03)
  • Bautz, Marshall W.; McDonald, Michael A. (IOP Publishing, 2015-01)
    We present a catalog of galaxy clusters selected via their Sunyaev-Zel'dovich (SZ) effect signature from 2500 deg[superscript 2] of South Pole Telescope (SPT) data. This work represents the complete sample of clusters ...
  • Andersson, Karl; Bautz, Marshall W.; McDonald, Michael A. (IOP Publishing, 2013-01)
    We present a catalog of galaxy cluster candidates, selected through their Sunyaev-Zel'dovich (SZ) effect signature in the first 720 deg[superscript 2] of the South Pole Telescope (SPT) survey. This area was mapped with the ...
  • Ajello, M.; Rebusco, Paola; Cappelluti, N.; Reimer, O.; Böhringer, H.; La Parola, V.; Cusumano, G. (Institute of Physics/American Astronomical Society, 2010-12)
    We report on the discovery of 10 additional galaxy clusters detected in the ongoing Swift/Burst Alert Telescope (BAT) all-sky survey. Among the newly BAT-discovered clusters there are Bullet, A85, Norma, and PKS 0745-19. ...
  • Ajello, M.; Rebusco, Paola; Cappelluti, N.; Reimer, O.; Böhringer, H.; Greiner, J.; Gehrels, N.; Tueller, J.; Moretti, A. (Institute of Physics/American Astronomical Society, 2009-01)
    We report the detection of 10 clusters of galaxies in the ongoing Swift/Burst Alert Telescope (BAT) all-sky survey. This sample, which mostly comprises merging clusters, was serendipitously detected in the 15-55 keV band. ...
  • Stinson, G. S.; Hennawi, J. F.; Springel, V.; Macciò, A. V.; Kannan, Rahul; Vogelsberger, Mark; Marinacci, Federico (Oxford University Press, 2016-02)
    We study how X-rays from stellar binary systems and the hot intracluster medium (ICM) affect the radiative cooling rates of gas in galaxies. Our study uses a novel implementation of gas cooling in the moving-mesh hydrodynamics ...
  • Snyder, Gregory F.; Lotz, Jennifer M.; Genel, Shy; McBride, Cameron K.; Pillepich, Annalisa; Nelson, Dylan; Sales, Laura V.; Sijacki, Debora; Hernquist, Lars; Springel, Volker; Torrey, Paul A.; Vogelsberger, Mark (Oxford University Press, 2015-12)
    We study how optical galaxy morphology depends on mass and star formation rate (SFR) in the Illustris Simulation. To do so, we measure automated galaxy structures in 10 808 simulated galaxies at z = 0 with stellar masses ...
  • Schwab, Josiah; Bolton, Adam S.; Rappaport, Saul A. (American Astronomical Society, 2010-01)
    Galaxy-scale strong gravitational lenses with measured stellar velocity dispersions allow a test of the weak-field metric on kiloparsec scales and a geometric measurement of the cosmological distance-redshift relation, ...
  • Bagchi, Arjun; Basu, Rudranil; Kakkar, Ashish; Mehra, Aditya (Springer Berlin Heidelberg, 2016-04)
    We investigate the symmetry structure of the non-relativistic limit of Yang-Mills theories. Generalising previous results in the Galilean limit of electrodynamics, we discover that for Yang-Mills theories there are a variety ...
  • Shin, Hyundong; Win, Moe Z. (Institute of Electrical and Electronics Engineers, 2009-04)
    In this paper, we derive Gallager's random coding error exponent for multiple-input multiple-output (MIMO) Rayleigh block-fading channels, assuming no channel-state information (CSI) at the transmitter and perfect CSI at ...
  • Chua, Lynn; Hossain, Chetak; Gyarfas, Andras (Hindawi Publishing Corporation, 2013)
    A coloring of the edges of the r-uniform complete hypergraph is a G[subscript r]-coloring if there is no rainbow simplex; that is, every set of r + l vertices contains two edges of the same color. The notion extends ...
