  • Savla, Ketan; Frazzoli, Emilio (Institute of Electrical and Electronics Engineers / IEEE Control Systems Society, 2010-08)
    In this technical note, we introduce a model of dynamical queue, in which the service time depends on the server utilization history. The proposed queueing model is motivated by widely accepted empirical laws describing ...
  • Leung, Debbie; Li, Ke; Smith, Graeme; Smolin, John A. (American Physical Society, 2014-07)
    Privacy is a fundamental feature of quantum mechanics. A coherently transmitted quantum state is inherently private. Remarkably, coherent quantum communication is not a prerequisite for privacy: there are quantum channels ...
  • Thaler, Jesse; Van Tilburg, Ken (Springer-Verlag, 2012-02)
    N -subjettiness is a jet shape designed to identify boosted hadronic objects such as top quarks. Given N subjet axes within a jet, N-subjettiness sums the angular distances of jet constituents to their nearest subjet axis. ...
  • Nieves, Veronica; Wang, Jingfeng; Bras, Rafael L.; Wood, Elizabeth B. (American Physical Society, 2010-09)
    Organizations of many variables in nature such as soil moisture and topography exhibit patterns with no dominant scales. The maximum entropy (ME) principle is proposed to show how these variables can be statistically ...
  • Zhang, Xiangxiong; Liu, Yuanyuan; Shu, Chi-Wang (Society for Industrial and Applied Mathematics, 2012-03)
    To easily generalize the maximum-principle-satisfying schemes for scalar conservation laws in [X. Zhang and C.-W. Shu, J. Comput. Phys., 229 (2010), pp. 3091–3120] to convection diffusion equations, we propose a nonconventional ...
  • Fox, Jacob; Lee, Choongbum; Sudakov, Benny (Springer Science + Business Media B.V., 2012-02)
    An old problem of Moser asks: what is the size of the largest union-free subfamily that one can guarantee in every family of m sets? A family of sets is called union-free if there are no three distinct sets in the family ...
  • Markakis, Mihalis G.; Tsitsiklis, John N.; Modiano, Eytan H. (Institute of Electrical and Electronics Engineers (IEEE), 2014-02)
    We consider the problem of scheduling in a single-hop switched network with a mix of heavy-tailed and light-tailed traffic and analyze the impact of heavy-tailed traffic on the performance of Max-Weight scheduling. As a ...
  • Morrison, Robert L., Jr.; Do, Minh N.; Munson, David C. (Institute of Electrical and Electronics Engineers, 2009-04)
    We present a new noniterative approach to synthetic aperture radar (SAR) autofocus, termed the multichannel autofocus (MCA) algorithm. The key in the approach is to exploit the multichannel redundancy of the defocusing ...
  • Naegle, Kristen Marie; Welsch, Roy E.; Yaffe, Michael B.; White, Forest M.; Lauffenburger, Douglas A. (Public Library of Science, 2011-07)
    Advances in proteomic technologies continue to substantially accelerate capability for generating experimental data on protein levels, states, and activities in biological samples. For example, studies on receptor tyrosine ...
  • Mitsos, Alexander; Chachuat, Benoit; Barton, Paul I. (Society for Industrial and Applied Mathematics, 2009-05)
    Theory and implementation for the global optimization of a wide class of algorithms is presented via convex/affine relaxations. The basis for the proposed relaxations is the systematic construction of subgradients for the ...
  • Stewart, Michelle L.; Fire, Emiko; Keating, Amy E.; Walensky, Loren D. (Nature Publishing Group, 2010-08)
    MCL-1 has emerged as a major oncogenic and chemoresistance factor. A screen of stapled peptide helices identified the MCL-1 BH3 domain as selectively inhibiting MCL-1 among the related anti-apoptotic Bcl-2 family members, ...
  • Birsoy, Kivanç; Wang, Tim; Possemato, Richard; Yilmaz, Omer H; Koch, Catherine E; Chen, Walter W; Hutchins, Amanda W; Gultekin, Yetis; Peterson, Tim R; Carette, Jan E; Brummelkamp, Thijn R; Clish, Clary B; Sabatini, David M (Nature Publishing Group, 2012-12)
    There is increasing evidence that oncogenic transformation modifies the metabolic program of cells. A common alteration is the upregulation of glycolysis, and efforts to target glycolytic enzymes for anticancer therapy are ...
  • Kraska, Tim; Pang, Gene; Franklin, Michael J.; Madden, Samuel R.; Fekete, Alan (Association for Computing Machinery, 2013-04)
    Replicating data across multiple data centers allows using data closer to the client, reducing latency for applications, and increases the availability in the event of a data center failure. MDCC (Multi-Data Center ...
  • Ding, Xu Chu; Smith, Stephen L.; Belta, Calin; Rus, Daniela L. (Institute of Electrical and Electronics Engineers (IEEE), 2011-12)
    In this paper, we develop a method to automatically generate a control policy for a dynamical system modeled as a Markov Decision Process (MDP). The control specification is given as a Linear Temporal Logic (LTL) formula ...
  • Ortiz, Alejandra Campbell; Ashton, Andrew; Nepf, Heidi (John Wiley & Sons, Inc/American Geophysical Union, 2013-12)
    The transport of fine sediment and organic matter plays an important role in the nutrient dynamics of shallow aquatic systems, and the fate of these particles is closely linked to vegetation. We describe the mean and ...
  • Mannor, Shie; Tsitsiklis, John N. (International Machine Learning Society, 2011-06)
    We consider finite horizon Markov decision processes under performance measures that involve both the mean and the variance of the cumulative reward. We show that either randomized or history-based policies can improve ...
  • Boning, Duane S.; Balakrishnan, Karthik, Ph. D. Massachusetts Institute of Technology. (Institute of Electrical and Electronics Engineers, 2009-10)
    The impact of contacts on device and circuit performance is becoming larger with technology scaling because of higher resistance as well as increased variability. Thus, techniques are needed for measurement, analysis, and ...
  • LaCurts, Katrina Leigh; Balakrishnan, Hari (Association for Computing Machinery, 2010-11)
    Despite many years of work in wireless mesh networks built using 802.11 radios, the performance and behavior of these networks in the wild is not well-understood. This lack of understanding is due in part to the lack of ...
  • Cowan, Ray Franklin; Fisher, Peter H.; Dujmic, Denis; Henderson, Shawn Wesley; Sciolla, Gabriella; Spitznagel, M.; Yamamoto, R. K.; Zhao, M. (American Physical Society, 2010-02)
    We present results for the moments of observed spectra in inclusive semileptonic B-meson decays to charm hadrons B̅ -->X[subscript c]ℓ-nu[over-bar]. Moments of the hadronic-mass and the combined mass-and-energy spectra for ...
  • O’Hanley, Harry; Buongiorno, Jacopo; Hu, Lin-wen; McKrell, Thomas J.; Hu, Lin-Wen (ASME International, 2011-11)
    Nanofluids are being considered for heat transfer applications. However, their thermo-physical properties are poorly known. Here we focus on nanofluid specific heat capacity. Currently, there exist two models to predict a ...
