  • Cheow, Lih Feng; Han, Jongyoon (American Chemical Society, 2011-09)
    We describe an electrokinetic concentration-enhanced aptamer affinity probe electrophoresis assay to achieve highly sensitive and quantitative detection of protein targets in a microfluidic device. The key weaknesses of ...
  • Blondel, Vincent D.; Hendrickx, Julien; Tsitsiklis, John N. (Society for Industrial and Applied Mathematics, 2010-10)
    We study a simple continuous-time multiagent system related to Krause's model of opinion dynamics: each agent holds a real value, and this value is continuously attracted by every other value differing from it by less than ...
  • Ivan, Ioana Elisabeta; Mitzenmacher, Michael; Thaler, Justin; Yuen, Henry (Institute of Electrical and Electronics Engineers (IEEE), 2012-08)
    Khanna and Sudan [2] studied a natural model of continuous time channels where signals are corrupted by the effects of both noise and delay, and showed that, surprisingly, in some cases both are not enough to prevent such ...
  • Choi, Han-Lim; How, Jonathan P. (2010-06)
    This paper addresses planning of continuous paths for mobile sensors to reduce uncertainty in some quantities of interest in the future. The mutual information between the continuous measurement path and the future ...
  • Barkeshli, Maissam; McGreevy, John (American Physical Society, 2012-08)
    One of the most successful theories of a non-Fermi-liquid metallic state is the composite Fermi-liquid (CFL) theory of the half-filled Landau level. In this paper, we study continuous quantum phase transitions out of the ...
  • Lupo, Cosmo; Lloyd, Seth (American Physical Society, 2015-12)
    Quantum physics allows for unconditionally secure communication through insecure communication channels. The achievable rates of quantum-secured communication are fundamentally limited by the laws of quantum physics and ...
  • Cerf, Nicolas J.; Garcia-Patron Sanchez, Raul (American Physical Society, 2009-03)
    A continuous-variable quantum key distribution protocol based on squeezed states and heterodyne detection is introduced and shown to attain higher secret key rates over a noisy line than any other one-way Gaussian protocol. ...
  • Rumpler, Joseph J.; Fonstad, Clifton G., Jr. (Institute of Electrical and Electronics Engineers, 2009-06)
    We report the successful integration on silicon of small footprint, low-threshold electrically pumped edge-emitting lasers by a new approach incorporating microcleaving technology to produce 6-mum-thick platelet lasers ...
  • Torrezan de Sousa, Antonio Carlos; Han, Seong-Tae; Mastovsky, Ivan; Shapiro, Michael; Sirigiri, Jagadishwar R.; Temkin, Richard J.; Barnes, Alexander; Griffin, Robert Guy (Institute of Electrical and Electronics Engineers / IEEE Nuclear and Plasma Sciences Society, 2010-06)
    The design, operation, and characterization of a continuous-wave (CW) tunable second-harmonic 460-GHz gyrotron are reported. The gyrotron is intended to be used as a submillimeter-wave source for 700-MHz nuclear magnetic ...
  • Huang, Hsin-Fu; Zahn, Markus; Lemaire, Elisabeth (Elsevier, 2010-05)
    A continuum mechanical model is presented to analyze the negative electrorheological responses of a particle-liquid mixture with the suspended micro-particles undergoing Quincke rotation for both Couette and Poiseuille ...
  • Henann, David Lee; Kamrin, Kenneth N. (American Physical Society, 2014-10)
    Recent dense granular flow experiments have shown that shear deformation in one region of a granular medium fluidizes its entirety, including regions far from the sheared zone, effectively erasing the yield condition ...
  • Dunatunga, Sachith Anurudde; Kamrin, Kenneth N (Cambridge University Press, 2015-08)
    We propose and numerically implement a constitutive framework for granular media that allows the material to traverse through its many common phases during the flow process. When dense, the material is treated as a ...
  • Schlaufman, Kevin C. (Institute of Physics/American Astronomical Society, 2015-01)
    It has long been known that stars with high metallicity are more likely to host giant planets than stars with low metallicity. Yet the connection between host star metallicity and the properties of small planets is only ...
  • Pinto, Pedro C.; Win, Moe Z. (Institute of Electrical and Electronics Engineers, 2010-10)
    The intrinsically secure communications graph (iS-graph) is a random graph which captures the connections that can be securely established over a large-scale network, in the presence of eavesdroppers. It is based on ...
  • Hutchinson, Ian H.; Patacchini, Leonardo (American Institute of Physic, 2009-06)
    The classical problem of the interaction of a nonemitting spherical body with a zero mean-free-path continuum plasma is solved numerically in the full range of physically allowed free parameters (electron Debye length to ...
  • Fritscher, Karl; Sharp, Greg; Wachinger, Christian; Golland, Polina (Institute of Electrical and Electronics Engineers (IEEE), 2015-12)
    We propose new methods for automatic segmentation of images based on an atlas of manually labeled scans and contours in the image. First, we introduce a Bayesian framework for creating initial label maps from manually ...
  • Schramm, Oded; Sheffield, Scott Roger (Springer-Verlag, 2012-09)
    Consider an instance h of the Gaussian free field on a simply connected planar domain D with boundary conditions −λ on one boundary arc and λ on the complementary arc, where λ is the special constant √π/8 . We argue that ...
  • Bathe, Mark; Zhou, Zhou; Munteanu, Emilia Laura; He, Jun; Ursell, Tristan; Huang, Kerwyn Casey; Chang, Fred (American Society for Cell Biology, 2014-10)
    The functions of the actin-myosin–based contractile ring in cytokinesis remain to be elucidated. Recent findings show that in the fission yeast Schizosaccharomyces pombe, cleavage furrow ingression is driven by polymerization ...
  • Sautner, Zacharias; Iyer, Rajkamal Janakiraman (MIT Press, 2018-03)
    We analyze contracts between a large buyer and her suppliers. We find that contracts with critical product suppliers contain more clauses that address moral hazard, primarily through monitoring. If holdup concerns are ...
  • Demaine, Erik D.; Hajiaghayi, Mohammad Taghi; Kawarabayashi, Ken-ichi (Association for Computing Machinery (ACM), 2011-06)
    We prove that any graph excluding a fixed minor can have its edges partitioned into a desired number k of color classes such that contracting the edges in any one color class results in a graph of treewidth linear in k. ...
