  • 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 ...
  • O'Hanley, Harrison F.; Buongiorno, Jacopo; McKrell, Thomas J.; Hu, Lin-Wen (Hindawi Pub. Corp., 2011-10)
    Nanofluids are being considered for heat transfer applications; therefore it is important to know their thermophysical properties accurately. In this paper we focused on nanofluid specific heat capacity. Currently, there ...

    Charge sensing with quantum point-contacts (QPCs) is a technique widely used in semiconductor quantum-dot research. Understanding the physics of this measurement process, as well as finding ways of suppressing unwanted ...
  • Fallon, Maurice Francis; Papadopoulos, Georgios; Leonard, John Joseph (Institute of Electrical and Electronics Engineers (IEEE), 2010-05)
    In recent years underwater survey and surveillance missions with more than a single Autonomous Underwater Vehicle (AUV) have become more common thanks to more reliable and cheaper platforms, as well as the addition of ...
  • Pan, Z. -H.; Fedorov, A. V.; Gardner, Dillon Richard; Lee, Young S.; Chu, S.; Valla, T. (American Physical Society, 2012-05)
    Gapless surface states on topological insulators are protected from elastic scattering on nonmagnetic impurities which makes them promising candidates for low-power electronic applications. However, for widespread applications, ...
  • Cowan, Ray Franklin; Dujmic, D.; Sciolla, Gabriella; Flood, Kevin T. (American Physical Society, 2013-10)
    Based on the full BABAR data sample, we report improved measurements of the ratios R(D) = B([¯ over B] → D[subscript τ][superscript −][¯ over v][subscript τ])/B([¯ over B] → Dℓ[superscript −][¯ over v]ℓ) and R(D[superscript ...
