  • Stewart, Iain; Chien, Yang-Ting; Simmons-Duffin, David; Schwartz, Matthew D. (American Physical Society, 2012-02)
    Soft interactions with high-energy jets are explored in radial coordinates which exploit the approximately conformal behavior of perturbative gauge theories. In these coordinates, the jets, approximated by Wilson lines, ...
  • Ogle, Patrick; Boulanger, Francois; Guillard, Pierre; Evans, Daniel A.; Antonucci, Robert; Appleton, P. N.; Nesvadba, Nicole; Leipski, Christian (IOP Publishing, 2010-11)
    H[subscript 2] pure-rotational emission lines are detected from warm (100-1500 K) molecular gas in [17 over 55] (31% of) radio galaxies at redshift z < 0.22 observed with the Spitzer IR Spectrograph. The summed H[subscript ...
  • Stewart, Iain; Tackmann, Frank J.; Walsh, Jonathan R.; Zuberi, Saba (American Physical Society, 2014-03)
    We present predictions for Higgs production via gluon fusion with a p[subscript T] veto on jets and with the resummation of jet-veto logarithms at NNLL′ + NNLO order. These results incorporate explicit O(α[2 over s]) ...
  • Chesler, Paul Michael; Rajagopal, Krishna (American Physical Society, 2014-07)
    We present calculations in which an energetic light quark shoots through a finite slab of strongly coupled N = 4 supersymmetric Yang-Mills (SYM) plasma, with thickness L, focusing on what comes out on the other side. We ...
  • D'Eramo, Francesco; Liu, Hong; Rajagopal, Krishna (World Scientific Publishing, 2011-07)
    We analyze the transverse momentum broadening in the absence of radiation of an energetic parton propagating through quark-gluon plasma via Soft Collinear Effective Theory (SCET). We show that the probability for picking ...
  • Seibold, Benjamin; Rosales, Rodolfo R.; Nave, Jean-Christophe (American Institute of Mathematical Sciences (AIMS), 2012-06)
    We present a systematic methodology to develop high order accurate numerical approaches for linear advection problems. These methods are based on evolving parts of the jet of the solution in time, and are thus called jet ...
  • Larkoski, Andrew James; Neill, Duff Austin; Thaler, Jesse (Springer-Verlag/International School for Advanced Studies (SISSA), 2014-04)
    Broadening is a classic jet observable that probes the transverse momentum structure of jets. Traditionally, broadening has been measured with respect to the thrust axis, which is aligned along the (hemisphere) jet momentum ...
  • Lee, C.; Stewart, Iain; Thaler, Jesse (IOP Publishing, 2012-05)
    In this paper, we review recent theoretical progress and the latest experimental results in jet substructure from the Tevatron and the LHC. We review the status of and outlook for calculation and simulation tools for ...
  • Moult, Ian James; Stewart, Iain (Springer-Verlag, 2014-09)
    Far off-shell Higgs production in H → WW, ZZ, is a particularly powerful probe of Higgs properties, allowing one to disentangle Higgs width and coupling information unavailable in on-shell rate measurements. These measurements ...
  • Beckmann, Nathan Zachary; Sanchez, Daniel (Institute of Electrical and Electronics Engineers (IEEE), 2013-09)
    Shared last-level caches, widely used in chip-multi-processors (CMPs), face two fundamental limitations. First, the latency and energy of shared caches degrade as the system scales up. Second, when multiple workloads share ...
  • Yao, Huan; Royster, Thomas C., IV; McLamb, Jeffrey W.; Mustafa, Mehmet; Yazdani, Navid (Institute of Electrical and Electronics Engineers, 2010-01)
    One of the main components of the next generation protected military satellite communication systems is dynamic bandwidth resource allocation (DBRA). A centralized DBRA algorithm on the satellite dynamically grants terminals ...
  • Weller, Daniel Stuart; Goyal, Vivek K. (Institute of Electrical and Electronics Engineers (IEEE), 2009-05)
    Sampling error due to jitter, or noise in the sample times, affects the precision of analog-to-digital converters in a significant, nonlinear fashion. In this paper, a polynomial least squares (PLS) estimator is derived ...
  • Silbey, Susan S. (Wildy, Simmonds and Hill Publishing, 2012-07)
    Each winter in the northern cities of the United States, a familiar scene illustrates tacit and deeply sedimented, yet common invocations of law. After a heavy snow storm, one can see old chairs, traffic cones, milk crates, ...
  • Costinot, Arnaud (MIT Press, 2009-08)
    This paper analyzes the determinants of protectionism in a small open economy with search frictions. In this environment, jobs generate rents whose access depends on the level of trade protection. By raising the domestic ...
  • Urban, Glen L.; Hauser, John R. (Springer, 2010-11)
    Profile of John D. C. Little
  • Sze, Vivienne; Chandrakasan, Anantha P. (Springer-Verlag, 2012-05)
    This paper uses joint algorithm and architecture design to enable high coding efficiency in conjunction with high processing speed and low area cost. Specifically, it presents several optimizations that can be performed ...
  • Shi, Xiaomeng; Lun, Desmond S.; Medard, Muriel; Kötter, Ralf; Meldrim, James C.; Barry, Andrew James (Institute of Electrical and Electronics Engineers, 2010-02)
    Automated estimation of DNA base-sequences is an important step in genomics and in many other emerging fields in biological and medical sciences. Current automated sequencers process single strands only. To improve the ...
  • Lee, Hyang-Won; Shin, Minsu; Park, Won-Seok; Chong, Song (Institute of Electrical and Electronics Engineers, 2009-09)
    This paper revisits burst contention resolution problems in optical burst switching (OBS) networks from the viewpoint of network utility maximization. Burst collision occurs when two or more bursts access the same wavelength ...
  • Nguyen, Hien M.; Sutton, Bradley P.; Morrison, Robert L., Jr.; Do, Minh N. (Institute of Electrical and Electronics Engineers, 2009-02)
    Magnetic resonance imaging (MRI) uses applied spatial variations in the magnetic field to encode spatial position. Therefore, nonuniformities in the main magnetic field can cause image distortions. In order to correct the ...
  • Venkataraman, Archana; Rathi, Yogesh; Kubicki, Marek; Westin, Carl-Fredrik; Golland, Polina (Springer Berlin / Heidelberg, 2010-09)
    We propose a novel probabilistic framework to merge information from DWI tractography and resting-state fMRI correlations. In particular, we model the interaction of latent anatomical and functional connectivity templates ...
