  • Michaeli, Karen; Fu, Liang (American Physical Society, 2012-10)
    Unconventional superconductors host a plethora of interesting physical phenomena. However, the standard theory of superconductors suggests that unconventional pairing is highly sensitive to disorder, and hence can only be ...
  • Schebaum, Oliver; Fabretti, Savio; Moodera, Jagadeesh S.; Thomas, Andy (IOP Publishing, 2012-03)
    We prepared magnetic tunnel junctions with one ferromagnetic and one superconducting Al–Si electrode. Pure cobalt electrodes were compared with a Co–Fe–B alloy and the Heusler compound Co[subscript 2]FeAl. The polarization ...
  • Ofori-Okai, Benjamin Kwasi; Tao, Ye; Pezzagna, S.; Chang, K.; Loretz, M.; Schirhagl, R.; Moores, B. A.; Groot-Berning, K.; Meijer, J.; Degen, C. L. (American Physical Society, 2012-08)
    We investigate spin and optical properties of individual nitrogen vacancy centers located within 1–10 nm from the diamond surface. We observe stable defects with a characteristic optically detected magnetic-resonance ...
  • Sommer, Ariel Tjodolv; Ku, Mark Jen-Hao; Zwierlein, Martin Wolfram (Institute of Physics Publishing, 2011-05)
    We present measurements of spin transport in ultracold gases of fermionic 6Li in a mixture of two spin states at a Feshbach resonance. In particular, we study the spin-dipole mode, where the two spin components are displaced ...
  • Knutson, Heather A.; Cowan, Nicolas B.; Christiansen, Jessie L.; Agol, Eric; Deming, Drake; Désert, Jean-Michel; Charbonneau, David; Henry, Gregory W.; Homeier, Derek; Langton, Jonathan; Madhusudhan, Nikku; Laughlin, Gregory; Seager, Sara (IOP Publishing, 2011-06)
    In this paper, we describe a uniform analysis of eight transits and eleven secondary eclipses of the extrasolar planet GJ 436b obtained in the 3.6, 4.5, and 8.0 μm bands using the IRAC instrument on the Spitzer Space ...
  • Galvin, Brendan D.; Denning, Daniel Prudden; Horvitz, H. Robert (National Academy of Sciences (U.S.), 2011-02)
    To identify genes involved in protecting cells from programmed cell death in Caenorhabditis elegans, we performed a genetic screen to isolate mutations that cause an increase in the number of programmed cell deaths. We ...
  • Xiao, Xinshu; Wang, Zefeng; Jang, Minyoung; Nutiu, Razvan; Wang, Eric T.; Burge, Christopher B. (Nature Publishing Group, 2009-09)
    Pre-mRNA splicing is regulated through the combinatorial activity of RNA motifs, including splice sites and splicing regulatory elements. Here we show that the activity of the G-run (polyguanine sequence) class of splicing ...
  • Jia, Yali; Tan, Ou; Tokayer, Jason; Potsaid, Benjamin M.; Wang, Yimin; Liu, Jonathan Jaoshin; Kraus, Martin Franz Georg; Subhash, Hrebesh; Fujimoto, James G.; Hornegger, Joachim; Huang, David (Optical Society of America, 2012-02)
    Amplitude decorrelation measurement is sensitive to transverse flow and immune to phase noise in comparison to Doppler and other phase-based approaches. However, the high axial resolution of OCT makes it very sensitive to ...
  • Chuangsuwanich, Ekapol; Cyphers, David Scott; Glass, James R.; Teller, Seth (Institute of Electrical and Electronics Engineers, 2010-12)
    We describe a speech system for commanding robots in human-occupied outdoor military supply depots. To operate in such environments, the robots must be as easy to interact with as are humans, i.e. they must reliably ...
  • Muramatsu, Brandon; McKinney, Andrew F.; Long, Phillip D.; Zornig, John (Institute of Electrical and Electronics Engineers, 2009-08)
    The SpokenMedia project's goal is to increase the effectiveness of web-based lecture media by improving the search and discoverability of specific, relevant media segments. SpokenMedia creates media-linked transcripts that ...
  • Jaffe, Robert L.; Kardar, Mehran; Maghrebi, Mohammad F. (American Physical Society, 2012-06)
    We study the quantum electrodynamics vacuum in the presence of a body rotating along its axis of symmetry and show that the object spontaneously emits energy if it is lossy. The radiated power is expressed as a general ...
  • Faas, Henryk; Watson, Nicki; Borkowski, Andrew W.; Jasanoff, Alan Pradip; King, Oliver D.; Steele, Andrew D.; Lindquist, Susan; Jackson, Walker S. (Elsevier Inc., 2009-08)
    A crucial tenet of the prion hypothesis is that misfolding of the prion protein (PrP) induced by mutations associated with familial prion disease is, in an otherwise normal mammalian brain, sufficient to generate the ...
  • Osburne, Marcia; Holmbeck, Brianne M.; Coe, Allison; Chisholm, Sallie (Penny) (Wiley-Blackwell, 2011-09)
    The marine cyanobacterium Prochlorococcus, the smallest and most abundant oxygenic phototroph, has an extremely streamlined genome and a high rate of protein evolution. High-light adapted strains of Prochlorococcus in ...
  • Lee, Sang Ah; Winkler-Rhoades, Nathan; Spelke, Elizabeth S. (Public Library of Science, 2012-12)
    Humans and animals recover their sense of position and orientation using properties of the surface layout, but the processes underlying this ability are disputed. Although behavioral and neurophysiological experiments on ...
  • Lee, Patrick A.; Ko, Wing Ho; Wen, Xiao-Gang; Ran, Ying (American Physical Society, 2009-01)
    The Dirac spin liquid was proposed to be the ground state of the spin-1/2 kagomé antiferromagnets. In a magnetic field B, we show that the state with Fermi pocket is unstable to the Landau level (LL) state. The LL state ...
  • Kontnik, Renee; Bosak, Tanja; Butcher, Rebecca A.; Brocks, Jochen J.; Losick, Richard; Clardy, Jon; Pearson, Ann (American Chemical Society (ACS), 2008-07)
    Sporulene, a C35-terpenoid hydrocarbon with an unusual pentacyclic structure, is produced by Bacillus subtilis during sporulation.
  • Acemoglu, Daron; Ozdaglar, Asuman E.; Parandehgheibi, Ali (Elsevier B.V., 2010-02)
    We provide a model to investigate the tension between information aggregation and spread of misinformation in large societies (conceptualized as networks of agents communicating with each other). Each individual holds a ...
  • Bakke, Eirik; Karger, David R.; Miller, Robert C. (Association for Computing Machinery (ACM), 2011-05)
    A key feature of relational database applications is managing \emph{plural} relationships---one-to-many and many-to-many---between entities. However, since it is often infeasible to adopt or develop a new database application ...
  • Kroll, Jesse; Frossard, Amanda A.; Shaw, Patrick M.; Russell, Lynn M.; Canagaratna, Manjula R.; Worsnop, Douglas R.; Quinn, Patricia K. (American Geophysical Union (AGU), 2011-03)
    The composition of Arctic aerosol, especially during the springtime Arctic haze, may play an important role in the radiative balance of the Arctic. The contribution of organic components to Arctic haze has only recently ...
  • Bellini, A.; Chernozhukov, Victor V.; Wang, Lie (Oxford University Press, 2011-12)
    We propose a pivotal method for estimating high-dimensional sparse linear regression models, where the overall number of regressors p is large, possibly much larger than n, but only s regressors are significant. The method ...
