  • Thomason, Moriah E.; Race, Elizabeth; Burrows, Brittany; Glover, Gary H.; Gabrieli, John D. E.; Gabrieli, Susan (MIT Press Journals, 2010-05)
    A core aspect of working memory (WM) is the capacity to maintain goal-relevant information in mind, but little is known about how this capacity develops in the human brain. We compared brain activation, via fMRI, between ...

Robin (Public Library of Science, 2012-12)
    The natural diversity of plant metabolism has long been a source for human medicines. One group of plant-derived compounds, the monoterpene indole alkaloids (MIAs), includes well-documented therapeutic agents used in the ...
  • Hu, Qing; Kumar, Sushil; Qin, Qi; Williams, Benjamin S.; Reno, John L. (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    We report a novel tuning mechanism based on a “wire-laser” with subwavelength transverse dimensions(w≪λ). By manipulating the waveguided mode propagating outside the cavity, frequency tuning of ∼137GHz (3.6%) is demonstrated ...
  • Raja, Waseem Khan; Padgen, Michael R.; Williams, James K.; Gertler, Frank; Wyckoff, Jeffrey B.; Condeelis, John S.; Castracane, James (2012-03)
    Cancer cells create a unique microenvironment in vivo that enables migration to distant organs. To better understand the tumor microenvironment, special tools and devices are required to monitor the interactions between ...
  • Hsieh, David; Wray, L. A.; Thomale, R.; Platt, C.; Qian, D.; Chen, G. F.; Luo, J. L.; Wang, N. L.; Hasan, M. Z. (American Physical Society, 2012-10)
    We present a polarization-resolved study of the low-energy band structure in the optimally doped iron pnictide superconductor Ba[subscript 0.6]K[subscript 0.4]Fe[subscript 2]As[subscript 2] (T[subscript c]=37 K) using ...
  • Heo, Myoung-Sun; Rvachov, Timur M.; Cotta, Dylan A.; Ketterle, Wolfgang; Wang, Tout Taotao (American Physical Society, 2013-04)
    Collisions of [superscript 6]Li[subscript 2] molecules with free [superscript 6]Li atoms reveal a striking deviation from universal predictions based on long-range van der Waals interactions. Li[subscript 2] closed-channel ...
  • Bonkowski, Michael S.; Pointer, Kelli; Pletcher, Scott D.; Libert, Sergiy V.; Guarente, Leonard Pershing (Wiley Blackwell, 2012-07)
    The variation of individual life spans, even in highly inbred cohorts of animals and under strictly controlled environmental conditions, is substantial and not well understood. This variation in part could be due to ...
  • Strauss, Jacob A.; Lesniewski-Laas, Christopher Tur; Paluska, Justin Mazzola; Ford, Bryan; Morris, Robert Tappan; Kaashoek, M. Frans (Association for Computing Machinery, 2010-01)
    This paper proposes a new storage model, device transparency, in which users view and manage their entire data collection from any of their devices, even from disconnected storage-limited devices holding only a subset of ...
  • White, Richard Mark; Cech, Jennifer; Ratanasirintrawoot, Sutheera; Lin, Charles Y.; Rahl, Peter B.; Burke, Christopher J.; Langdon, Erin; Tomlinson, Matthew L.; Mosher, Jack; Kaufman, Charles; Chen, Frank; Long, Hannah K.; Kramer, Martin; Datta, Sumon; Neuberg, Donna; Granter, Scott; Young, Richard A.; Morrison, Sean; Wheeler, Grant N.; Zon, Leonard I. (Nature Publishing Group, 2011-03)
    Melanoma is a tumour of transformed melanocytes, which are originally derived from the embryonic neural crest. It is unknown to what extent the programs that regulate neural crest development interact with mutations in the ...
  • Van Voorhis, Troy; Kowalczyk, Timothy Daniel; Kaduk, Benjamin J.; Wang, Lee-Ping; Cheng, Chiao-Lun; Wu, Qin (Annual Reviews, 2010-05)
    Diabatic states have a long history in chemistry, beginning with early valence bond pictures of molecular bonding and extending through the construction of model potential energy surfaces to the modern proliferation of ...
  • French, Katherine L.; Tosca, Nicholas J.; Cao, Changqun; Summons, Roger Everett (Elsevier Ltd., 2012-05)
    Many biogeochemical anomalies coincide with the Late Permian Extinction (LPE; 252.28 Ma). Several mechanisms have been proposed to explain the moretane/hopane anomaly that has been identified in samples from Meishan GSSP ...

  • Marshall, John C.; Maze, Guillaume (American Meteorological Society, 2011-10)
    Analyzed fields of ocean circulation and the flux form of the potential vorticity equation are used to map the creation and subsequent circulation of low potential vorticity waters known as subtropical mode water (STMW) ...
  • Sills, E. Scott; Perloe, Mark; Tucker, Michael J.; Kaplan, Carolyn R.; Schattman, Glenn L.; Genton, Marc G. (BioMed Central Ltd, 2001-08)

  • Saunderson, James F.; Parrilo, Pablo A.; Willsky, Alan S. (Institute of Electrical and Electronics Engineers (IEEE), 2013-12)
    Identifying a subspace containing signals of interest in additive noise is a basic system identification problem. Under natural assumptions, this problem is known as the Frisch scheme and can be cast as decomposing an n × ...
