  • 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 J. (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 James (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 ...
  • 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 ...
  • Andersson, K.; 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 ...
  • 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, ...
  • 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 ...
  • Luo, Tengfei; Garg, Jivtesh; Shiomi, Junichiro; Esfarjani, Keivan; Chen, Gang (IOP Publishing, 2013-01)
    In this paper, thermal conductivity of crystalline GaAs is calculated using first-principles lattice dynamics. The harmonic and cubic force constants are obtained by fitting them to the force-displacement data from density ...
  • Frazzoli, Emilio; Savla, Ketan (Institute of Electrical and Electronics Engineers, 2010-01)
    In this paper we consider a class of dynamic vehicle routing problems, in which a number of mobile agents in the plane must visit target points generated over time by a stochastic process. It is desired to design motion ...
  • Borgs, Christian; Chayes, Jennifer; Karrer, Brian; Meeder, Brendan; Ravi, R.; Reagans, Ray Eugene; Sayedi, Amin (Springer-Verlag, 2010-12)
    We study the effect of information overload on user engagement in an asymmetric social network like Twitter. We introduce simple game-theoretic models that capture rate competition between celebrities producing updates in ...
  • Cardenas, Alvaro A.; Amin, Saurabh; Schwartz, Galina; Dong, Roy; Sastry, Shankar (Institute of Electrical and Electronics Engineers (IEEE), 2012-10)
    We introduce a model for the operational costs of an electric distribution utility. The model focuses on two of the new services that are enabled by the Advanced Metering Infrastructure (AMI): (1) the fine-grained anomaly ...
  • Singal, J.; Petrosian, V.; Ko, Allan (IOP Publishing, 2014-04)
    We present the redshift evolutions and distributions of the gamma-ray luminosity and photon spectral index of flat spectrum radio quasar (FSRQ) type blazars, using non-parametric methods to obtain the evolutions and ...
  • Chung, J. W.; Ryu, Kevin K.; Palacios, Tomas (Institute of Electrical and Electronics Engineers (IEEE), 2010-11)
    The Si substrate of GaN-on-Si wafers offers new opportunities to increase the functionality and performance of nitride-based devices. This paper will review three examples of these new devices/systems. First, GaN-on-Si ...
  • Lu, Bin; Piedra, Daniel; Palacios, Tomas (Institute of Electrical and Electronics Engineers (IEEE), 2010-12)
    Between 5 and 10% of the world's electricity is wasted as dissipated heat in the power electronic circuits needed, for example, in computer power supplies, motor drives or the power inverters of photovoltaic systems. This ...
  • Lan, Tian; Wen, Xiao-Gang; Wang, Juven (American Physical Society, 2015-02)
    Gapped domain walls, as topological line defects between (2+1)D topologically ordered states, are examined. We provide simple criteria to determine the existence of gapped domain walls, which apply to both Abelian and ...
  • Wen, Xiao-Gang; Liu, Min; Liu, Zheng-Xin (American Physical Society, 2011-08)
    We study different quantum phases in integer spin systems with on-site D[subscript 2h]=D[subscript 2]⊗Z[subscript 2] and translation symmetry. We find four distinct nontrivial phases in S=1 spin chains despite the fact ...
  • Wang, Chong; Potter, Andrew C.; Todadri, Senthil (American Physical Society, 2013-09)
    It is well known that the three-dimensional (3D) electronic topological insulator (TI) with charge-conservation and time-reversal symmetry cannot have a trivial insulating surface that preserves symmetry. It is often ...
