  • Mekdeci, Brian Anthony; Ross, Adam Michael; Rhodes, Donna H.; Hastings, Daniel E. (International Council on Systems Engineering, 2011-06)
    Previous research has identified design principles that enable survivability for systems, but it is unclear if these principles are appropriate and sufficient for systems of systems as well. This paper presents a preliminary ...
  • Lee, Chia-Hua; Bose, Suman; Van Vliet, Krystyn J.; Karp, Jeffrey Michael; Karnik, Rohit (American Chemical Society (ACS), 2010-12)
    The lateral displacement of cells orthogonal to a flow stream by rolling on asymmetrical receptor patterns presents a new opportunity for the label-free separation and analysis of cells. Understanding the nature of cell ...
  • Dembélé, Lassina; Kumar, Abhinav (Springer Berlin Heidelberg, 2015-07)
    We describe several explicit examples of simple abelian surfaces over real quadratic fields with real multiplication and everywhere good reduction. These examples provide evidence for the Eichler–Shimura conjecture for ...
  • Kaul, Michael G.; Chen, Ou; Chen, Yue; Li, Nan; Okada, Satoshi; Cordero, Jose M.; Heine, Markus; Farrar, Christian T.; Adam, Gerhard; Ittrich, Harald; Nielsen, Peter; Bawendi, Moungi G.; Wei, He; Bruns, Oliver Thomas; Hansen, Eric Calvin; Barch, Mariya; Wisniowska, Agata Elzbieta; Jasanoff, Alan Pradip; Montana Fernandez, Daniel M (National Academy of Sciences (U.S.), 2017-02)
    Medical imaging is routine in the diagnosis and staging of a wide range of medical conditions. In particular, magnetic resonance imaging (MRI) is critical for visualizing soft tissue and organs, with over 60 million MRI ...
  • Boriskina, Svetlana V; Chen, Gang (Elsevier, 2013-10)
    Maximum efficiency of ideal single-junction photovoltaic (PV) cells is limited to 33% (for 1 sun illumination) by intrinsic losses such as band edge thermalization, radiative recombination, and inability to absorb below-bandgap ...
  • Hohm, Olaf; Samtleben, Henning (American Physical Society, 2014-03)
    We present the details of the recently constructed E[subscript 6(6)]-covariant extension of 11-dimensional supergravity. This theory requires a 5 + 27-dimensional spacetime in which the “internal” coordinates transform in ...
  • Hohm, Olaf; Samtleben, Henning (American Physical Society, 2014-03)
    We introduce the exceptional field theory for the group E[subscript 7(7)], based on a (4+56)-dimensional spacetime subject to a covariant section condition. The “internal” generalized diffeomorphisms of the coordinates in ...
  • Hohm, Olaf; Samtleben, Henning (American Physical Society, 2014-09)
    We develop exceptional field theory for E[subscript 8(8)], defined on a (3 + 248)-dimensional generalized spacetime with extended coordinates in the adjoint representation of E[subscript 8(8)]. The fields transform under ...
  • Fogt, Ryan L.; Jones, Megan E.; Jones, Julie M.; Goergens, Chad A.; Solomon, Susan (American Meteorological Society, 2017-10)
    The meteorological conditions during the Amundsen and Scott South Pole expeditions in 1911/12 are examined using a combination of observations collected during the expeditions as well as modern reanalysis and reconstructed ...
  • Holton, Richard (Wiley-Blackwell Pubishers, 2010-12)
    Legal rules admit of exceptions; indeed, it has been a legal maxim that one can infer the existence of a rule from exceptions that are made to it. Hart claims that the exceptions do not admit of exhaustive statement (a ...

  • Yesilaltay, Ayce; Dokshin, Gregoriy A.; Busso, Dolores; Wang, Li; Galiani, Dalia; Vasile, Eliza; Quilaqueo, Linda; Orellana, Juan Andrés; Shalgi, Ruth; Dekel, Nava; Albertini, David F.; Rigotti, Attilio; Page, David C.; Krieger, Monty; Chavarria, Tony E.; Walzer, Dalia F. (National Academy of Sciences (U.S.), 2014-11)
    The HDL receptor scavenger receptor, class B type I (SR-BI) controls the structure and fate of plasma HDL. Female SR-BI KO mice are infertile, apparently because of their abnormal cholesterol-enriched HDL particles. We ...
  • Evans, Jeremy S.; Vydrov, Oleg A.; Van Voorhis, Troy (American Institute of Physics, 2009-07)
    We study real-time electron dynamics in a molecular junction with a variety of approximations to the electronic structure, toward the ultimate aim of determining what ingredients are crucial for the accurate prediction of ...
  • Reilly, D. J.; Taylor, J. M.; Petta, J. R.; Marcus, Charles M.; Hanson, Micah P.; Gossard, A. C. (American Physical Society, 2010-06)
    The influence of gate-controlled two-electron exchange on the relaxation of nuclear polarization in small ensembles (N∼10[superscript 6]) of nuclear spins is examined in a GaAs double quantum dot system. Waiting in the ...
  • Wei, Peng; Katmis, Ferhat; Assaf, Badih A.; Steinberg, Hadar; Jarillo-Herrero, Pablo; Heiman, D.; Moodera, Jagadeesh (American Physical Society, 2013-04)
    An exchange gap in the Dirac surface states of a topological insulator (TI) is necessary for observing the predicted unique features such as the topological magnetoelectric effect as well as to confine Majorana fermions. ...
  • Zhang, Xueyan; Nepf, Heidi (Springer Science + Business Media, 2011-06)
    This study describes the exchange flow between a region with open water and a region with a partial-depth porous obstruction, which represents the thermally-driven exchange that occurs between open water and floating ...
  • Guisinger, Alexandra; Singer, David Andrew (Cambridge University Press, 2010-04)
    If governments choose economic policies that often run counter to their public commitments, are those commitments meaningless? We argue that government proclamations can be critical in signaling economic policy intentions. ...
  • Kowalczyk, Timothy Daniel; Tsuchimochi, Takashi; Chen, Po-Ta; Top, Laken; Van Voorhis, Troy (American Institute of Physics, 2013-04)
    Restricted open-shell Kohn-Sham (ROKS) theory provides a powerful computational tool for calculating singlet excited state energies and dynamics. However, the possibility of multiple solutions to the ROKS equations — with ...
  • Difley, Seth; Van Voorhis, Troy (American Chemical Society, 2011-02)
    Charge transfer (CT) states and excitons are important in energy conversion processes that occur in organic light emitting devices (OLEDS) and organic solar cells. An ab initio density functional theory (DFT) method for ...
  • Abasto, D. F.; Mohseni, Masoud; Lloyd, Seth; Zanardi, P. (Royal Society, The, 2012-07)
    Symmetric couplings among aggregates of n chromophores increase the transfer rate of excitons by a factor n2, a quantum-mechanical phenomenon called ‘supertransfer’. In this work, we demonstrate how supertransfer effects ...
