  • Masuda, Hitomi; Nakamura, Kuniaki; Takata, Nozomu; Itoh, Bunsho; Hirose, Takashi; Moribe, Hiroki; Mekada, Eisuke; Okada, Masato (Elsevier, 2012-01)
    The transmembrane protein MIG-13 is a key regulator required for anterior migration of neural cells in Caenorhabditis elegans, but the signaling mechanisms involved remain unknown. Here, we isolated a suppressor mutation ...
  • Haldeman, Joe (Association for Computing Machinery, 2009-12)
    I’ve been a writer for 40 years, and my attitude toward writing machines has never been simple. Right now I’m sitting in a quiet one-room cabin in the Maine woods, writing in natural light with a fountain pen into a ...
  • Singer, David Andrew (Cambridge University Press, 2010-05)
    This article argues that the international financial consequences of immigration exert a substantial influence on the choice of exchange rate regimes in the developing world. Over the past two decades, migrant remittances ...
  • Bissember, Alex C.; Levina, Anna; Fu, Gregory C. (American Chemical Society, 2012-08)
    We have exploited a typically undesired elementary step in cross-coupling reactions, β-hydride elimination, to accomplish palladium-catalyzed dehydrohalogenations of alkyl bromides to form terminal olefins. We have applied ...
  • Linares, M.; Altamirano, D.; Chakrabarty, Deepto; Cumming, A.; Keek, L. (Institute of Physics Publishing, 2012-03)
    We present a comprehensive study of the thermonuclear bursts and millihertz quasi-periodic oscillations (mHz QPOs) from the neutron star (NS) transient and 11 Hz X-ray pulsar IGR J17480–2446, located in the globular cluster ...
  • Han, Xue; Qian, Xiaofeng; Bernstein, Jacob G.; Zhou, Huihui; Talei Franzesi, Giovanni; Stern, Patrick; Bronson, Roderick T.; Graybiel, Ann M.; Desimone, Robert; Boyden, Edward Stuart (Elsevier B.V., 2009-04)
    To understand how brain states and behaviors are generated by neural circuits, it would be useful to be able to perturb precisely the activity of specific cell types and pathways in the nonhuman primate nervous system. We ...
  • Malik, Wasim Q. (Institute of Electrical and Electronics Engineers, 2009-02)
    The dependence of multi-antenna capacity on bandwidth is characterized empirically for narrowband, wideband and ultrawideband indoor channels using spatial and polar arrays. It is shown that both the mean and the outage ...
  • Mecca, Vito F.; Krolik, Jeffrey L. (Institute of Electrical and Electronics Engineers, 2009-05)
    Multiple-input multiple-output (MIMO) radar is an emerging technology that has the capability of providing range dependent transmit-domain degrees of freedom via receiver processing. When providing these additional degrees ...
  • Chiani, Marco; Win, Moe Z.; Shin, Hyundong (Institute of Electrical and Electronics Engineers / IEEE Information Society, 2009-12)
    Multiple-input multiple-output (MIMO) systems are being considered as one of the key enabling technologies for future wireless networks. However, the decrease in capacity due to the presence of interferers in MIMO networks ...
  • Forsythe, Keith W.; Bliss, Daniel W., Jr. (Institute of Electrical and Electronics Engineers, 2010-02)
    Ground moving-target indication (GMTI) provides both an opportunity and challenge for coherent multiple-input multiple-output (MIMO) radar. MIMO techniques can improve a radar's angle estimation and the minimum detectable ...
  • Klein, Arno; Mensh, Brett; Ghosh, Satrajit; Tourville, Jason; Hirsch, Joy (BioMed Central Ltd, 2005-10)
    Background: To make inferences about brain structures or activity across multiple individuals, one first needs to determine the structural correspondences across their image data. We have recently developed Mindboggle as ...
  • Bewley, Kathryn D.; Firer‑Sherwood, Mackenzie A.; Mock, Jee‑Young; Ando, Nozomi; Drennan, Catherine L.; Elliott, Sean J.; Drennan, Catherine L. (Portland Press, 2012-12)
    Shewanella oneidensis MR-1 has the ability to use many external terminal electron acceptors during anaerobic respiration, such as DMSO. The pathway that facilitates this electron transfer includes the decahaem cytochrome ...
  • Muentener, Paul Jason; Bonawitz, Elizabeth; Horowitz, Alexandra; Schulz, Laura E. (Public Library of Science, 2012-04)
    Toddlers readily learn predictive relations between events (e.g., that event A predicts event B). However, they intervene on A to try to cause B only in a few contexts: When a dispositional agent initiates the event or ...
  • Grocholski, Brent; Catalli, Krystle C.; Shim, Sang-Heon; Prakapenka, Vitali (National Academy of Sciences, 2012-02)
    The discovery of a phase transition in Mg-silicate perovskite (Pv) to postperovskite (pPv) at lowermost mantle pressure-temperature (P - T) conditions may provide an explanation for the discontinuous increase in shear wave ...
  • Iida, Fumiya; Tedrake, Russell Louis (Institute of Electrical and Electronics Engineers, 2009-08)
    Although there has been an increasing interest in dynamic bipedal locomotion for significant improvement of energy efficiency and dexterity of mobile robots in the real world, their locomotion capabilities are still mostly ...
  • Iida, Fumiya; Tedrake, Russell Louis (Springer Netherlands, 2010-01)
    Toward our comprehensive understanding of legged locomotion in animals and machines, the compass gait model has been intensively studied for a systematic investigation of complex biped locomotion dynamics. While most of ...
  • Ballinger, Brad; Charlton, David; Demaine, Erik D.; Demaine, Martin L.; Iacono, John; Liu, Ching-Hao; Poon, Sheung-Hung (Springer Berlin / Heidelberg, 2009-07)
    Locked tree linkages have been known to exist in the plane since 1998, but it is still open whether they have a polynomial-time characterization. This paper examines the properties needed for planar trees to lock, with a ...
  • Wang, Liying; Zhang, Lihong; Liu, Zhangzhi; Zhao, Dehua; Liu, Xiaomeng; Zhang, Bo; Xie, Jianbo; Hong, Yuanyuan; Li, Pengfei; Chen, Sanfeng; Dixon, Ray; Li, Jilun (Public Library of Science, 2013-10)
    Most biological nitrogen fixation is catalyzed by molybdenum-dependent nitrogenase, an enzyme complex comprising two component proteins that contains three different metalloclusters. Diazotrophs contain a common core of ...
  • Forney, G. David, Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2011-01)
    Given a discrete-time linear system C, a shortest basis for C is a set of linearly independent generators for C with the least possible lengths. A basis B is a shortest basis if and only if it has the predictable span ...
  • Wang, Qiqi; Moin, Parviz; Iaccarino, Gianluca (Society for Industrial and Applied Mathematics, 2009-06)
    Adjoint equations of differential equations have seen widespread applications in optimization, inverse problems, and uncertainty quantification. A major challenge in solving adjoint equations for time dependent systems has ...
