  • Gollakota, Shyamnath; Perli, Samuel David; Katabi, Dina (Association for Computing Machinery (ACM), 2009-08)
    The throughput of existing MIMO LANs is limited by the number of antennas on the AP. This paper shows how to overcome this limit. It presents interference alignment and cancellation (IAC), a new approach for decoding ...
  • Adib, Fadel M.; Suresh Kumar, Swarun; Aryan, Omid; Gollakota, Shyamnath; Katabi, Dina (Association for Computing Machinery, 2013-09)
    Recent years have witnessed increasing interest in interference alignment which has been demonstrated to deliver gains for wireless networks both analytically and empirically. Typically, interference alignment is achieved ...
  • Bodas, Shreeshankar; Shah, Devavrat; Wischik, Damon (Institute of Electrical and Electronics Engineers (IEEE), 2012-01)
    This paper looks at the problem of designing wireless medium access algorithms. Inter-user interference at the receivers is an important characteristic of wireless networks. We show that decoding (or canceling) this ...
  • Newport, Calvin Charles; Kowalski, Dariusz R.; Guerraoui, Rachid; Gilbert, Seth (Institute of Electrical and Electronics Engineers, 2009-06)
    This paper presents an efficient protocol for reliably exchanging information in a single-hop, multi-channel radio network subject to unpredictable interference. We model the interference by an adversary that can simultaneously ...
  • Veysset, David Georges; Maznev, Alexei; Saini, Gagan; Kooi, Steven Earl; Pezeril, Thomas; Nelson, Keith Adam (American Institute of Physics, 2012-06)
    We apply time-resolved interferometric imaging to study laser-driven focused shock waves on the microscale. Shock waves are generated in a 10 μm-thick layer of water by sub-nanosecond laser pulses focused into a ring of ...
  • Poliannikov, Oleg V.; Malcolm, Alison E.; Djikpesse, Hugues; Prange, Michael (Society of Exploration Geophysicists, 2011-12)
    Hydraulic fracturing is the process of injecting high-pressure fluids into a reservoir to induce fractures and thus improve reservoir productivity. Microseismic event localization is used to locate created fractures. ...
  • Benkevitch, Leonid; Cappallo, Roger J.; Corey, Brian E.; Doeleman, Sheperd Samuel; Derome, Mark F.; Kincaid, Barton B.; Kratzenberg, Eric; Lonsdale, Colin John; McWhirter, Stephen R.; Oberoi, Divya; Rogers, Alan E. E.; Salah, Joseph E.; Whitney, Alan R.; Hewitt, Jacqueline N.; Matejek, Michael Scott; Morgan, Edward H.; Williams, Christopher Leigh (University of Chicago Press, The, 2010-10)
    The Murchison Wide-Field Array (MWA) is a low-frequency radio telescope, currently under construction, intended to search for the spectral signature of the epoch of reionization (EOR) and to probe the structure of the solar ...
  • Knap, M.; Gopalakrishnan, S.; Yao, N. Y.; Laumann, C. R.; Abanin, D. A.; Lukin, M. D.; Demler, E. A.; Serbyn, Maksym; Papic, Z. (American Physical Society, 2014-10)
    We propose a method for detecting many-body localization (MBL) in disordered spin systems. The method involves pulsed coherent spin manipulations that probe the dephasing of a given spin due to its entanglement with a set ...
  • Waller, Laura; Kim, Jungik; Shao-Horn, Yang; Barbastathis, George (Optical Society of America, 2009-08)
    We have developed a system that uses two 1D interferometric phase projections for reconstruction of 2D water content changes over time in situ in a proton exchange membrane (PEM) fuel cell system. By modifying the filtered ...
  • Tu, Shui Ping; Quante, Michael; Bhagat, Govind; Takaishi, Shigeo; Cui, Guanglin; Yang, Xiang Dong; Muthuplani, Sureshkumar; Shibata, Wataru; Fox, James G.; Pritchard, D. Mark; Wang, Timothy C. (American Association for Cancer Research, 2011-04)
    IFN-γ mediates responses to bacterial infection and autoimmune disease, but it is also an important tumor suppressor. It is upregulated in the gastric mucosa by chronic Helicobacter infection; however, whether it plays a ...
  • Hutchinson, Ian H. (American Physical Society, 2012-06)
    Large-scale particle-in-cell calculations of the plasma wake interactions of two negatively charged grains smaller than the Debye length are carried out using the coptic code over a wide range of subsonic plasma flow ...
  • Krasovskiy, Yuriy P.; Stone, Peter H. (American Meteorological Society, 2009-04)
    The authors introduce a four-box interhemispheric model of the meridional overturning circulation. A single box represents high latitudes in each hemisphere, and in contrast to earlier interhemispheric box models, low ...
  • Lemke, Angelika K.; Sandy, John D.; Voigt, Henning; Dreier, Rita; Lee, Jennifer H.; Grodzinsky, Alan J.; Mentlein, Rolf; Fay, Jakob; Schunke, Michael; Kurz, Bodo (Springer-Verlag, 2010-03)
    Pro-inflammatory cytokines induce meniscal matrix degradation and inhibition of endogenous repair mechanisms, but the pathogenic mechanisms behind this are mostly unknown. Therefore, we investigated details of interleukin-1 ...
  • Moawwad, Ahmed; Khadkikar, Vinod; Kirtley, James L., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2012-10)
    This paper proposes a stationary-frame control method for voltage unbalance compensation using Interline Photovoltaic (I-PV) power system. I-PV power systems are controlled to compensate voltage unbalance autonomously. The ...
  • Khadkikar, Vinod; Kirtley, James L., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    This paper presents a new system configuration for a large-scale Photovoltaic (PV) power system with multi-line transmission/distribution networks. A PV power plant is reconfigured in a way that two adjacent power system ...
  • Antras, Pol; Costinot, Arnaud (American Economic Association, 2010-12)
    This paper develops a simple model of international trade with intermediation. We consider an economy with two islands and two types of agents, farmers and traders. Farmers can produce two goods, but in order to sell ...
  • Pfeiffer, Andrew T.; Murray, Richard A.; Lin, Yijun; Wukitch, Stephen James; Binus, Alan; Gwinn, D. (Institute of Electrical and Electronics Engineers, 2009-08)
    ICRF operations with Alcator C-Mod consists of 4 transmitters, of which two are tunable within the 40 MHz to 80 MHz band. These transmitters were comprised of 3 stages all of which employed vacuum tube amplifiers. As a ...
  • Bourouiba, Lydia; Bartello, Peter (Cambridge University Press, 2007-08)
    Rotating homogeneous turbulence in a finite domain is studied using numerical simulations, with a particular emphasis on the interactions between the wave and zero-frequency modes. Numerical simulations of decaying homogeneous ...
  • Antras, Pol; Costinot, Arnaud (American Economic Association, 2010-05)
    The theory of international trade has paid scant attention to market institutions. Neither neoclassical theory nor new trade models typically specify the process by which supply and demand meet. Yet in the real world, ...
  • Oates, Daniel E.; Eom, Chang-Beom; Folkman, Chad M; Choi, Kyoung-Jin; Jang, Ho Won (Institute of Electrical and Electronics Engineers, 2009-06)
    We report intermodulation distortion (IMD) in high-quality epitaxial YBa[subscript 2]Cu[subscript 3]O[subscript 7-delta] (YBCO) thick films and multilayers prepared by pulsed-laser deposition (PLD) using multiple targets. ...
