  • Baugher, Britton W. H.; Jarillo-Herrero, Pablo; Lemme, Max C.; Bell, David C.; Williams, James R.; Stern, Lewis A.; Marcus, Charles M. (American Chemical Society (ACS), 2009-09)
    We report on the etching of graphene devices with a helium ion beam, including in situ electrical measurement during lithography. The etching process can be used to nanostructure and electrically isolate different regions ...
  • Bousso, Raphael; Freivogel, Benjamin W.; Leichenauer, Stefan; Rosenhaus, Vladimir (American Physical Society, 2011-01)
    Present treatments of eternal inflation regulate infinities by imposing a geometric cutoff. We point out that some matter systems reach the cutoff in finite time. This implies a nonzero probability for a novel type of ...
  • Smith, Aaron; Knittel, Christopher Roland (International Association for Energy Economics (IAEE), 2015-01)
    Ethanol made from corn comprises 10% of U.S. gasoline, up from 3% in 2003. This dramatic increase was spurred by recent policy initiatives such as the Renewable Fuel Standard and state-level blend mandates and supported ...
  • Setiya, Kieran (Wiley Blackwell, 2014-12)
    The doctor brings disturbing news: you have a condition that will affect any child you conceive in the next two months. The effect of the condition is that the child will suffer a serious, incurable ...
  • Levine, Sheen S.; Bernard, Mark; Bartelt, Valerie L.; Zajac, Edward J.; Stark, David; Apfelbaum, Evan Paul (National Academy of Sciences (U.S.), 2014-12)
    Markets are central to modern society, so their failures can be devastating. Here, we examine a prominent failure: price bubbles. Bubbles emerge when traders err collectively in pricing, causing misfit between market prices ...
  • Zavala, Jesús; Cyr-Racine, Francis-Yan; Pfrommer, Christoph; Bringmann, Torsten; Sigurdson, Kris; Vogelsberger, Mark (Oxford University Press, 2016-05)
    We present the first simulations within an effective theory of structure formation (ETHOS), which includes the effect of interactions between dark matter and dark radiation on the linear initial power spectrum and dark ...
  • Cyr-Racine, Francis-Yan; Sigurdson, Kris; Zavala, Jesús; Bringmann, Torsten; Pfrommer, Christoph; Vogelsberger, Mark (American Physical Society, 2016-06)
    We formulate an effective theory of structure formation (ETHOS) that enables cosmological structure formation to be computed in almost any microphysical model of dark matter physics. This framework maps the detailed ...
  • Har-Peled, Sariel; Indyk, Piotr; Sidiropoulos, Anastasios (Society for Industrial and Applied Mathematics, 2013)
    A classical result in metric geometry asserts that any n-point metric admits a linear-size spanner of dilation O(log n) [PS89]. More generally, for any c > 1, any metric space admits a spanner of size O(n[superscript ...
  • Bhattacharya, Arpita; McIntosh, Kerri B.; Willis, Ian M.; Warner, Jonathan R. (Public Library of Science, 2011-08)
    It has recently become clear that the misassembly of ribosomes in eukaryotic cells can have deleterious effects that go far beyond a simple shortage of ribosomes. In this work we find that cells deficient in ribosomal ...
  • Heller, Ryan C.; Kang, Sukhyun; Lam, Wendy M.; Chen, Shuyan; Chan, Clara Sophia; Bell, Stephen P. (Elsevier B.V., 2011-07)
    Proper eukaryotic DNA replication requires temporal separation of helicase loading from helicase activation and replisome assembly. Using an in vitro assay for eukaryotic origin-dependent replication initiation, we ...
  • Chaudhuri, Swarat; Solar-Lezama, Armando (Springer-Verlag, 2012)
    We give a tutorial introduction to Euler, a system for solving difficult optimization problems involving programs.
  • Bates, R.B.; Ghoniem, A.F.; Bakshi, Akhilesh; Altantzis, Christos (Elsevier, 2015-03)
    Modeling the hydrodynamics of dense-solid gas flows is strongly affected by the wall boundary condition and in particular, the specularity coefficient ϕ which characterizes the tangential momentum transfer from the particles ...
  • Valkov, Boris; Rycroft, Chris H.; Kamrin, Kenneth N. (ASME International, 2015-03)
    We introduce an Eulerian approach for problems involving one or more soft solids immersed in a fluid, which permits mechanical interactions between all phases. The reference map variable is exploited to simulate ...
  • Wu, Hao-Yu; Rubinstein, Michael; Shih, Eugene; Guttag, John V.; Durand, Fredo; Freeman, William T. (Association for Computing Machinery, 2012-07)
    Our goal is to reveal temporal variations in videos that are difficult or impossible to see with the naked eye and display them in an indicative manner. Our method, which we call Eulerian Video Magnification, takes a ...
  • Orphanides, Athanasios (Springer US, 2014-07)
    This paper explores the dominant role of politics in decisions made by euro area governments during the crisis. Decisions that appear to have been driven by local political considerations to the detriment of the euro area ...
  • Duteil, M.; Pope, E. C.; de Polavieja, G. G.; Fürtbauer, I.; Brown, M. R.; King, A. J.; Perez Escudero, Alfonso (Royal Society, 2016-11)
    Ocean acidification (OA)—caused by rising concentrations of carbon dioxide (CO₂)—is thought to be a major threat to marine ecosystems and has been shown to induce behavioural alterations in fish. Here we show behavioural ...
  • Siemens, Mark; Li, Qing; Murname, Margaret M.; Kapteyn, Henry C.; Yang, Ronggui; Anderson, Erik; Nelson, Keith Adam (Institute of Electrical and Electronics Engineers, 2009-08)
    We use coherent extreme ultraviolet radiation to probe surface acoustic wave propagation in nickel-on-sapphire nanostructures. We observe no acoustic dispersion over SAW wavelengths down to 200 nm, meaning the SAW propagation ...
  • Falk, Matthias; Pyles, R. D.; Ustin, S. L.; Paw U, K. T.; Whiting, M. L.; Sanden, B. L.; Brown, P. H.; Xu, Liyi (American Meteorological Society, 2014-04)
    Among the uncertain consequences of climate change on agriculture are changes in timing and quantity of precipitation together with predicted higher temperatures and changes in length of growing season. The understanding ...
  • Barnhart, Cynthia; Fearing, Douglas (Transportation Research Board, 2011-07)
    The collaborative decision-making (CDM) framework introduced into ground delay programs in the late 1990s is an integral component of FAA's traffic flow management (TFM) procedures. CDM allows FAA to act as a mediator when ...
  • Choi, WooJhon; Boas, David A.; Clermont, Allen C.; Feener, Edward P.; Moult, Eric Michael; Baumann, Bernhard; Fujimoto, James G (SPIE, 2017-01)
    The purpose of this study is to evaluate the suitability of five different anesthetic protocols (isoflurane, isoflurane–xylazine, pentobarbital, ketamine–xylazine, and ketamine–xylazine–vecuronium) for functional blood ...
