  • Kolpak, Alexie M.; Ismail-Beigi, S. (American Physical Society, 2012-05)
    Phenomenological models suggest that thin epitaxial SrTiO[subscript 3] films on silicon will exhibit ferroelectric behavior as a result of compressive strain. However, such models do not include atomic-scale interface ...
  • Emori, Satoru; Bono, David C.; Beach, Geoffrey Stephen (American Institute of Physics, 2012-07)
    Current-driven domain wall (DW) motion is investigated in Pt/Co/GdOx nanostrips with perpendicular magnetic anisotropy. Measurements of the propagation field and the energy barrier for thermally activated DW motion reveal ...
  • Jaishankar, Aditya; Sharma, Vivek; McKinley, Gareth H. (Royal Society of Chemistry, The, 2011-08)
    Protein–surfactant mixtures arise in many industrial and biological systems, and indeed, blood itself is a mixture of serum albumins along with various other surface-active components. Bovine serum albumin (BSA) solutions, ...
  • Voldman, Joel (Institute of Electrical and Electronics Engineers (IEEE), 2009-06)
    To detect electrical properties of cells, we have developed a method called iso-dielectric separation (IDS), where cells are placed in a spatially varying electric field and a spatially varying conductivity gradient that ...

  • 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 ...

    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 ...
