  • 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 ...
  • 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 ...
  • 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.
  • 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 ...
  • 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 ...
  • Schmalensee, Richard (Oxford University Press, 2012-01)
    Building on a review of experience in the United States and the European Union, this article advances four main propositions concerning policies aimed at increasing electricity generation from renewable energy. First, who ...
  • Fulcoly, Daniel O.; Rhodes, Donna H.; Ross, Adam Michael (Elsevier, 2012-03)
    Complex engineering systems face many unknowns with respect to their operating contexts and time-varying stakeholder needs over their lifespan. A useful means for partitioning this problem is to consider a set of static ...
  • Patnaik, Somani; Brunskill, Emma; Thies, William (Institute of Electrical and Electronics Engineers, 2009-04)
    While mobile phones have found broad application in reporting health, financial, and environmental data, there has been little study of the possible errors incurred during mobile data collection. This paper provides the ...
  • Lucas, Deborah J. (Ernst & Young Global Limited, 2014-11)
    In the wake of the financial crisis, the Dodd–Frank Act established the Financial Stability Oversight Council (FSOC) and the Office of Financial Research (OFR) to address the concern that policymakers lacked sufficient ...
  • Do, Loi Hung; Xue, Genqiang; Que, Lawrence; Lippard, Stephen J. (American Chemical Society (ACS), 2012-01)
    The composition of a (μ-oxo)diiron(III) complex coordinated by tris[(3,5-dimethyl-4-methoxy)pyridyl-2-methyl]amine (R[subscript 3]TPA) ligands was investigated. Characterization using a variety of spectroscopic methods and ...
  • Cook, Kaitlyn; Benitez, Alejandra; Fu, Casey L.; Tintle, Nathan (Frontiers Research Foundation, 2014-04)
    The new class of rare variant tests has usually been evaluated assuming perfect genotype information. In reality, rare variant genotypes may be incorrect, and so rare variant tests should be robust to imperfect data. Errors ...
  • Shatova, Tatyana A.; Lee, Jungkyu K.; Kaastrup, Kaja; Heimer, Brandon Walter; Sikes, Hadley (Royal Society of Chemistry, 2014-04)
    Hypermethylation of CpG islands in gene promoter regions has been shown to be a predictive biomarker for certain diseases. Most current methods for methylation profiling are not well-suited for clinical analysis. Here, we ...
