    Motivated by long-term human exploration missions which could benefit from robotic assistants, a prototype thruster based on an Ion-Drag Pump was developed. This thruster utilizes no consumable propellant. Its operated by ...
  • Kerman, Andrew J.; Yang, Joel K. W.; Molnar, Richard J.; Dauler, Eric A.; Berggren, Karl K. (American Physical Society, 2009-03)
    We investigate the role of electrothermal feedback in the operation of superconducting nanowire single-photon detectors (SNSPDs). It is found that the desired mode of operation for SNSPDs is only achieved if this feedback ...
  • Buschhorn, Samuel T.; Kessler, Seth S.; Lachman-Senesh, Noa; Gavin, Jennifer; Thomas, Greg; Wardle, Brian L. (American Institute of Aeronautics and Astronautics, 2013-04)
    Ice protection systems (IPS) are critical components for many aerospace flight vehicles, including commercial transports and unmanned aerial systems (UAS), and can include anti-icing, de-icing, ice sensing, etc. Here, an ...
  • Marsili, Francesco; Najafi, Faraz; Herder, Charles Henry; Berggren, Karl K. (American Institute of Physics (AIP), 2011-03)
    We developed an electrothermal model of NbN superconducting nanowire avalanche photodetectors (SNAPs) on sapphire substrates. SNAPs are single-photon detectors consisting of the parallel connection of N superconducting ...
  • Rollins, A. W.; Fry, J. L.; Hunter, James; Kroll, Jesse; Worsnop, D. R.; Singaram, S. W.; Cohen, R. C. (Copernicus Publications, 2010-02)
    Four hydroxynitrates (R(OH)R'ONO2) representative of atmospheric volatile organic compound (VOC) oxidation products were synthesized, nebulized and sampled into an Aerodyne High Resolution Time of Flight Aerosol Mass ...

    We present a high-resolution elemental-abundance analysis for a sample of 23 very metal-poor ([Fe/H] < −2.0) stars, 12 of which are extremely metal-poor ([Fe/H] < −3.0), and 4 of which are ultra-metal-poor ([Fe/H] < −4.0). ...

D.; Lee, Alex K.Y.; Liggio, John (American Geophysical Union (AGU), 2015-05)
    A large data set including surface, aircraft, and laboratory observations of the atomic oxygen-to-carbon (O:C) and hydrogen-to-carbon (H:C) ratios of organic aerosol (OA) is synthesized and corrected using a recently ...
  • Canagaratna, M. R.; Jimenez, J. L.; Kessler, Sean Herbert; Massoli, P.; Hildebrandt Ruiz, L.; Fortner, E. C.; Williams, L. R.; Wilson, K. R.; Surratt, J. D.; Donahue, Neil M.; Jayne, John T.; Worsnop, D. R.; Kroll, Jesse; Chen, Qi (Copernicus GmbH, 2015-01)
    Elemental compositions of organic aerosol (OA) particles provide useful constraints on OA sources, chemical evolution, and effects. The Aerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) is ...
  • Costinot, Arnaud (Econometric Society, 2009-07)
    Comparative advantage, whether driven by technology or factor endowment, is at the core of neoclassical trade theory. Using tools from the mathematics of complementarity, this paper offers a simple yet unifying perspective ...
  • Costinot, Arnaud; Wang, Su; Vogel, Jonathan (Oxford University Press, 2012-05)
    This article develops an elementary theory of global supply chains. We consider a world economy with an arbitrary number of countries, one factor of production, a continuum of intermediate goods and one final good. Production ...
  • Dong, Guogang; Yang, Qiong; Wang, Qiang; Kim, Yong-Ick; Wood, Thammajun L.; Osteryoung, Katherine W.; van Oudenaarden, Alexander; Golden, Susan S. (Elsevier B.V., 2010-02)
    A circadian clock coordinates physiology and behavior in diverse groups of living organisms. Another major cyclic cellular event, the cell cycle, is regulated by the circadian clock in the few cases where linkage of these ...
  • Mayers, Jared R.; Torrence, Margaret E.; Fiske, Brian Prescott; Davidson, Shawn Michael; Papagiannakopoulos, Thales; Dayton, Talya Lucia; Vander Heiden, Matthew G. (Nature Publishing Group, 2014-09)
    Most patients with pancreatic ductal adenocarcinoma (PDAC) are diagnosed with advanced disease and survive less than 12 months. PDAC has been linked with obesity and glucose intolerance, but whether changes in circulating ...
  • Espelin, Christopher W.; Goldsipe, Arthur C.; Sorger, Peter K.; Lauffenburger, Douglas A.; de Graaf, David; Hendriks, Bart S. (Royal Society of Chemistry, 2010-07)
    Rheumatoid arthritis (RA) is a complex, multicellular disease involving a delicate balance between both pro- and anti-inflammatory cytokines which ultimately determines the disease phenotype. The simultaneous presence of ...
  • Dahlem, Marcus Vinicius Sobral; Holzwarth, Charles W.; Khilo, Anatol M.; Kaertner, Franz X.; Smith, Henry Ignatius; Ippen, Erich P. (Optical Society of America, 2010-05)
    A wide-band, eleven-channel second-order filterbank fabricated on an SOI platform is demonstrated with tunable channel spacing and a 20 GHz single-channel bandwidth. The tuning efficiency is ~28 μW/GHz/ring.
  • Sheltzer, Jason Meyer; Smith, Joan C. (National Academy of Sciences (U.S.), 2014-06)
    Women make up over one-half of all doctoral recipients in biology-related fields but are vastly underrepresented at the faculty level in the life sciences. To explore the current causes of women’s underrepresentation in ...
