  • 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. ...
  • 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 ...
  • 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 ...
  • Rusch, Doris C.; Weise, Matthew J. (Association for Computing Machinery (ACM), 2008-08)
    In this paper we will tackle the question of how thinking about game design as metaphorical process can help game designers to systematically expand the experiential scope of videogames. Sharing Eric Zimmerman's and Katie ...
  • Rusch, Doris C.; Weise, Matthew J. (Association for Computing Machinery (ACM), 2008)
    In this paper we will tackle the question of how thinking about game design as metaphorical process can help game designers to systematically expand the experiential scope of videogames. Sharing Eric Zimmerman's and Katie ...
  • Fernandez-Vara, Clara (Digital Games Research Association, 2011-01)
    In the problematic exploration of the narrative potential of videogames, one of the clearest aspects that bridge stories and games is space. This paper examines the different devices that videogames have used to incorporate ...
  • Tan, Philip; Fernandez-Vara, Clara (Association for Computing Machinery (ACM), 2008-11)
    The inclusion of a practicum is one of the main challenges in the game studies curriculum, especially when it comes to teaching professional practices to students. This paper presents how professional management methodologies ...
  • Belenky, Alexander S. (Springer Berlin Heidelberg, 2015-03)
    The problem of developing a decision support system for estimating a) the scale of incorporating available renewable sources of energy (such as solar and wind energy) in a part of a country’s electrical grid (called a ...
  • 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 ...
  • Amin, Saurabh; Schwartz, Galina A.; Cardenas, Alvaro A.; Sastry, S. Shankar; Amin, Saurabhci (Institute of Electrical and Electronics Engineers (IEEE), 2015-02)
    The smart grid refers to the modernization of the power grid infrastructure with new technologies, enabling a more intelligently networked automated system with the goal of improving efficiency, reliability, and security, ...
  • 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 ...
  • Wu, William; Kaashoek, Nicolaas; Tzamos, Christos; Weinberg, Matthew; Daskalakis, Konstantinos (Association for Computing Machinery (ACM), 2015-03)
    An efficient peer grading mechanism is proposed for grading the multitude of assignments in online courses. This novel approach is based on game theory and mechanism design. A set of assumptions and a mathematical model ...
  • 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 ...
  • Kinde, B.; Amon, Angelika B.; Unal, Elcin (American Association for the Advancement of Science (AAAS), 2011-06)
    Eukaryotic organisms age, yet detrimental age-associated traits are not passed on to progeny. How life span is reset from one generation to the next is not known. We show that in budding yeast resetting of life span occurs ...
