  • Massachusetts Institute of Technology. Department of Mathematics; Brubaker, Benjamin Brock; Brubaker, Benjamin Brock (Birkhauser Boston, 2012)
    We study spherical Whittaker functions on a metaplectic cover of GL(r + 1) over a nonarchimedean local eld using lattice models from statistical mechanics. An explicit description of this Whittaker function was given ...
  • Hanna, Jacob; Markoulaki, Styliani; Mitalipova, Maisam; Cheng, Albert W.; Cassady, John P.; Staerk, Judith; Carey, Bryce W.; Lengner, Christopher J.; Foreman, Ruth K.; Love, Jennifer; Gao, Qing; Kim, Jongpil; Jaenisch, Rudolf (Elsevier, 2009-05)
    Embryonic stem (ES) cells are isolated from the inner cell mass (ICM) of blastocysts, whereas epiblast stem cells (EpiSCs) are derived from the post-implantation epiblast and display a restricted developmental potential. ...
  • Soto, R.; Martinez, M. N.; Baibich, M. N.; Florez Uribe, Juan Manuel; Vargas, P. (American Physical Society, 2009-05)
    It is well known that the spin-chain compound Ca[subscript 3]Co[subscript 2]O[subscript 6] exhibits interesting plateaus in the magnetization as a function of the magnetic field at low temperatures. The origin of them is ...
  • Kerman, Andrew J. (American Physical Society, 2010-01)
    We propose a superconducting qubit design, based on a tunable rf SQUID and nanowire kinetic inductors, which has a dramatically reduced transverse electromagnetic coupling to its environment, so that its excited state ...
  • Byl, Katie; Tedrake, Russell Louis (Sage, 2009-06)
    Legged robots that operate in the real world are inherently subject to stochasticity in their dynamics and uncertainty about the terrain. Owing to limited energy budgets and limited control authority, these “disturbances” ...
  • Valastyan, Scott; Weinberg, Robert A. (Springer (Biomed Central Ltd.), 2010-11)
    Recent studies have implicated the microRNA biogenesis enzyme Dicer as a suppressor of breast carcinoma metastasis and elucidated upstream signaling pathways that control Dicer levels.
  • Hynes, Richard O.; Hynes, Richard O. (Elsevier, 2011-12)
    Two recent papers in Cancer Cell (Lu et al., this issue of Cancer Cell, and Kang et al.) illustrate means whereby acquisition of VCAM-1 by tumor cells can promote metastasis. First, monocyte/macrophages expressing α4 ...
  • Ottesen, Elizabeth; Marin, Roman, III; Preston, Christina M.; Young, Curtis Robert, III; Ryan, John P.; Scholin, Christopher A.; DeLong, Edward (Nature Publishing Group, 2011-06)
    Planktonic microbial activity and community structure is dynamic, and can change dramatically on time scales of hours to days. Yet for logistical reasons, this temporal scale is typically under-sampled in the marine ...
  • Ventouras, Laure-Anne; Wilson, Samuel T.; Karl, David M.; Martinez, Asuncion; DeLong, Edward (Frontiers Research Foundation, 2013-11)
    Aerobic degradation of methylphosphonate (MPn) by marine bacterioplankton has been hypothesized to contribute significantly to the ocean's methane supersaturation, yet little is known about MPn utilization by marine microbes. ...
  • Sanders, J. G.; Beinart, R. A.; Stewart, F. J.; Delong, Edward; Girguis, P. R.; DeLong, Edward (Nature Publishing Group, 2013-04)
    Despite the ubiquity of chemoautotrophic symbioses at hydrothermal vents, our understanding of the influence of environmental chemistry on symbiont metabolism is limited. Transcriptomic analyses are useful for linking ...
  • Mickley, Loretta J.; Jacob, Daniel J.; Leibensperger, Eric Michael; Zhang, L.; Fisher, J.A.; Pye, Havala Olson Taylor; Tai, Amos P.K. (Copernicus GmbH, 2012-03)
    We applied a multiple linear regression model to understand the relationships of PM[subscript 2.5] with meteorological variables in the contiguous US and from there to infer the sensitivity of PM[subscript 2.5] to climate ...
  • Fendt, Sarah-Maria; Bell, Eric L.; Keibler, Mark Andrew; Davidson, Shawn Michael; Wirth, Gregory J.; Fiske, Brian; Mayers, Jared R.; Schwab, Matthias; Bellinger, Gary; Csibi, Alfredo; Patnaik, Akash; Blouin, Marie Jose; Cantley, Lewis C.; Guarente, Leonard Pershing; Blenis, John; Pollak, Michael N.; Olumi, Aria F.; Vander Heiden, Matthew G.; Stephanopoulos, Gregory (American Association for Cancer Research, 2013-05)
    Metformin inhibits cancer cell proliferation, and epidemiology studies suggest an association with increased survival in patients with cancer taking metformin; however, the mechanism by which metformin improves cancer ...
  • Rothman, Daniel H.; Fournier, Gregory P.; French, Katherine Louise; Alm, Eric J.; Boyle, Edward A.; Summons, Roger Everett; Cao, Changqun (National Academy of Sciences (U.S.), 2014-04)
    The end-Permian extinction is associated with a mysterious disruption to Earth’s carbon cycle. Here we identify causal mechanisms via three observations. First, we show that geochemical signals indicate superexponential ...
  • Lu, Yi-Chun; Gasteiger, Hubert A.; Shao-Horn, Yang (Electrochemical Society, 2011-03)
    This study presents a new method to quantitatively determine the electrocatalytic activity of Vulcan carbon and Vulcan-supported Au nanoparticles, dispersed as catalyst thin films on glass carbon, for oxygen reduction in ...
  • Liu, Adrian Chi-Yan; Tegmark, Max Erik (American Physical Society, 2011-05)
    The technique of 21 cm tomography promises to be a powerful tool for estimating cosmological parameters, constraining the epoch of reionization, and probing the so-called dark ages. However, realizing this promise will ...
  • Barley, Maya E.; Armoundas, Antonis A.; Cohen, Richard J. (Institute of Electrical and Electronics Engineers, 2009-04)
    Treatment of hemodynamically unstable ventricular arrhythmias requires rapid and accurate localization of the reentrant circuit. We have previously described an algorithm that uses the single-equivalent moving dipole model ...
  • O'Donnell, Charles William; Waldispuhl, Jerome; Lis, Mieszko; Halfmann, Randal Arthur; Devadas, Srinivas; Lindquist, Susan; Berger, Bonnie (Oxford University Press, 2011-07)
    Motivation: Proteins of all kinds can self-assemble into highly ordered β-sheet aggregates known as amyloid fibrils, important both biologically and clinically. However, the specific molecular structure of a fibril can ...
  • Diephuis, Bradford J.; Tearney, Guillermo J.; Liu, Linbo; Chu, Kengyeh K.; Houser, Grace H.; Li, Yao; Wilsterman, Eric J.; Shastry, Suresh; Dierksen, Gregory; Birket, Susan E.; Birket, Susan E.; Byan-Parker, Suzanne; Grizzle, William E.; Sorscher, Eric J.; Rowe, Steven M. (Public Library of Science, 2013-01)
    We demonstrate the use of a high resolution form of optical coherence tomography, termed micro-OCT (μOCT), for investigating the functional microanatomy of airway epithelia. μOCT captures several key parameters governing ...

    Global algorithms can improve the analysis of fluorescence energy transfer (FRET) measurement based on fluorescence lifetime microscopy. However, global analysis of FRET data is also susceptible to experimental artifacts. ...
  • Yu, Li; Chang, Wen-Yao; Zuo, Kewei; Wang, Jean; Yu, Douglas; Boning, Duane S. (Institute of Electrical and Electronics Engineers (IEEE), 2012-03)
    As continued scaling becomes increasingly difficult, 3D integration with through silicon vias (TSVs) has emerged as a viable solution to achieve higher bandwidth and power efficiency. Mechanical stress induced by thermal ...
