  • Cardamone, Caroline N.; Abbott, Jonathan E.; Rayyan, Saif; Seaton, Daniel; Pawl, Andrew; Pritchard, David E. (American Institute of Physics, 2011-08)
    Item response theory is useful in both the development and evaluation of assessments and in computing standardized measures of student performance. In item response theory, individual parameters (difficulty, discrimination) ...
  • Stalnaker, Robert (Springer Netherlands, 2008-12)
    This is a discussion of the problem of extending the basic AGM belief revision theory to iterated belief revision: the problem of formulating rules, not only for revising a basic belief state in response to potential new ...
  • Horstmeyer, Roarke William; Oh, Se Baek; Raskar, Ramesh (Optical Society of America, 2010-10)
    We present an iterative camera aperture design procedure, which determines an optimal mask pattern based on a sparse set of desired intensity distributions at different focal depths. This iterative method uses the ambiguity ...
  • Fudenberg, Geoffrey; McCord, Rachel Patton; Naumova, Natalia; Goloborodko, Anton; Lajoie, Bryan R; Dekker, Job; Imakaev, Maksim Viktorovich; Mirny, Leonid A. (Nature Publishing Group, 2012-09)
    Extracting biologically meaningful information from chromosomal interactions obtained with genome-wide chromosome conformation capture (3C) analyses requires the elimination of systematic biases. We present a computational ...
  • Karger, David R.; Oh, Sewoong; Shah, Devavrat (Neural Information Processing Systems, 2011-12)
    Crowdsourcing systems, in which tasks are electronically distributed to numerous “information piece-workers”, have emerged as an effective paradigm for humanpowered solving of large scale problems in domains such as image ...
  • Jo, Gyu-Boong; Lee, Ye-Ryoung; Choi, Jae-Hoon; Christensen, Caleb A.; Kim, Tony H.; Pritchard, David E.; Ketterle, Wolfgang; Thywissen, Joseph H. (American Association for the Advancement of Science (AAAS), 2009-09)
    Can a gas of spin-up and spin-down fermions become ferromagnetic because of repulsive interactions? We addressed this question, for which there is not yet a definitive theoretical answer, in an experiment with an ultracold ...
  • Chern, Gia-Wei; Chubukov, Andrey V.; Nandkishore, Rahul (American Physical Society, 2012-05)
    We consider electrons on a honeycomb or triangular lattice doped to the saddle point of the band structure. We assume the system parameters are such that spin density wave (SDW) order emerges below a temperature T[subscript ...
  • Suckale, Jenny; Hager, Bradford H.; Elkins-Tanton, Linda T.; Nave, Jean-Christophe (American Geophysical Union, 2010-07)
    This is the second paper of two that examine numerical simulations of buoyancy-driven flow in the presence of large viscosity contrasts. In the first paper, we demonstrated that a combination of three numerical tools, an ...

  • Trigo Neri Tabuada, Goncalo Jo; Marcolli, Matilde (Independent University of Moscow, 2014-07)
    In this article one extends the classical theory of (intermediate) Jacobians to the “noncommutative world”. Concretely, one constructs a Q-linear additive Jacobian functor N → J(N) from the category of noncommutative Chow ...
  • Leithinger, Daniel; Olwal, Alex; Ishii, Hiroshi; Follmer, Sean Weston; Cheng, Nadia Gen San (Association for Computing Machinery (ACM), 2012-10)
    Malleable and organic user interfaces have the potential to enable radically new forms of interactions and expressiveness through flexible, free-form and computationally controlled shapes and displays. This work, specifically ...
  • Ou, Jifei; Yao, Lining; Tauber, Daniel; Niiyama, Ryuma; Ishii, Hiroshi; Steimle, Jurgen (Association for Computing Machinery (ACM), 2014-02)
    This works introduces layer jamming as an enabling technology for designing deformable, stiffness-tunable, thin sheet interfaces. Interfaces that exhibit tunable stiffness properties can yield dynamic haptic feedback and ...
  • Samuels, Richard J.; Schoff, James L. (National Bureau of Asian Research, 2013-10)
    This chapter examines the future of Japan’s hedged dependence on U.S. extended deterrence and encourages more imaginative thinking about potential outcomes and strategic implications as the second nuclear age unfolds.
  • Samuels, Richard J. (Muse - Johns Hopkins University Press, 2013)
    For some Japanese political entrepreneurs, the March 2011 catastrophe in Tohoku (3.11) was a warning for Japan to “put it in gear” and head in a new direction—away from nuclear power or toward a muscular military. For ...
  • Schmalensee, Richard (Sloan School of Management, 2011-03)
    This short essay, forthcoming in Competition Policy International, summarizes and evaluates Jeffrey Rohlfs’ 1974 Bell Journal paper, “A Theory of Interdependent Demand for a Telecommunications Service.” Rohlfs’ work ...
  • Taylor, Frank E. (Springer-Verlag, 2015-01)
    The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton–proton collision data with a centre-of-mass energy of s√=7 TeV corresponding to an integrated ...
  • Ma, Frank (Elsevier, 2013-05)
    The jet fragmentation function of inclusive jets with p[subscript T] > 100 GeV/c in PbPb collisions is measured for reconstructed charged particles with p[subscript T] > 1 GeV/c within the jet cone. A data sample of PbPb ...
  • Jouttenus, Teppo Tapani (American Physical Society, 2010-05)
    The jet function for the factorized cross section e[superscript +]e[superscript -] into dijets is given as a function of the jet invariant mass s and with a generic jet algorithm at O(αs). We demonstrate the results using ...
  • Stevens, Justin; van Nieuwenhuizen, Gerrit Jan (American Physical Society, 2014-03)
    Azimuthal angular correlations of charged hadrons with respect to the axis of a reconstructed (trigger) jet in Au + Au and p + p collisions at √s[subscript NN] = 200  GeV in STAR are presented. The trigger jet population ...
  • Tackmann, Frank J.; Waalewijn, Wouter J.; Jouttenus, Teppo Tapani; Stewart, Iain (American Physical Society, 2013-09)
    The invariant mass of a jet is a benchmark variable describing the structure of jets at the LHC. We calculate the jet mass spectrum for Higgs plus one jet at the LHC at next-to-next-to-leading logarithmic (NNLL) order using ...
