  • Abel, Zachary Ryan; Demaine, Erik D.; Demaine, Martin L.; Ito, Hiro; Snoeyink, Jack; Uehara, Ryuhei (2014-08)
    We investigate folding problems for a class of petal polygons P, which have an n-polygonal base B surrounded by a sequence of triangles. We give linear time algorithms using constant precision to determine if P can fold ...
  • Banerjee, Abhijit; Duflo, Esther; Hornbeck, Richard (American Economic Association, 2014-05)
    Microfinance institutions have started to bundle their basic loans with other financial services, such as health insurance. Using a randomized control trial in Karnataka, India, we evaluate the impact on loan renewal from ...
  • Taylor, John Ryan; Ferrari, Raffaele (American Meteorological Society, 2010-06)
    In this study, the influence of a geostrophically balanced horizontal density gradient on turbulent convection in the ocean is examined using numerical simulations and a theoretical scaling analysis. Starting with uniform ...
  • Person, Michael J.; Elliot, James L.; Gulbis, Amanda A. S.; Hubbard, William B.; McCarthy, D.W.; Kulesa, Craig A.; Benecchi, Susan D. (Elsevier, 2009-06)
    We apply scintillation theory to stellar signal fluctuations in the high-resolution, high signal/noise, dual-wavelength data from the MMT observation of the 2007 March 18 occultation of P445.3 by Pluto. A well-defined high ...
  • MacMinn, Christopher W.; Juanes, Ruben (American Geophysical Union (AGU), 2013-05)
    When carbon dioxide (CO[subscript 2]) dissolves into water, the density of water increases. This seemingly insubstantial phenomenon has profound implications for geologic carbon sequestration. Here we show, by means of ...
  • Brinkema, Eugenie Alexandra (B. Price, 2011-01)
    The roof, the roof, the roof is on fire. The roof, the roof, the roof is on fire. The roof, the roof, the roof is on fire. We don’t need no water let the motherfucker burn. Burn, motherfucker, burn. —Bloodhound Gang, ...
  • Dahle, Hakon; Sarazin, C. L.; Lopez, Laura A.; Kouveliotou, C.; Patel, S. K.; Rol, E.; van der Horst, A. J.; Fynbo, J. P. U.; Wijers, R. A. M. J.; Burrows, David N.; Gehrels, N.; Grupe, D.; Ramirez-Ruiz, E.; Michalowski, M. J. (Institute of Physics/American Astronomical Society, 2013-07)
    We have identified a merging galaxy cluster with evidence of two distinct subclusters. The X-ray and optical data suggest that the subclusters are presently moving away from each other after closest approach. This cluster ...
  • Feingold, Joseph; Gibson, Daniel J.; DePasquale, Brian; Graybiel, Ann M. (National Academy of Sciences (U.S.), 2015-11)
    Studies of neural oscillations in the beta band (13–30 Hz) have demonstrated modulations in beta-band power associated with sensory and motor events on time scales of 1 s or more, and have shown that these are exaggerated ...
  • Chemali, Jessica J.; Ching, ShiNung; Solt, Ken; Purdon, Patrick Lee; Brown, Emery N. (IOP Publishing, 2013-09)
    Objective. Burst suppression is an electroencephalogram pattern in which bursts of electrical activity alternate with an isoelectric state. This pattern is commonly seen in states of severely reduced brain activity such ...
  • Angalakudati, Mallik; Balwani, Siddharth; Calzada, Jorge; Chatterjee, Bikram; Perakis, Georgia; Raad, Nicolas; Uichanco, Joline (Institute for Operations Research and the Management Sciences (INFORMS), 2014-04)
    In this paper, we describe both applied and analytical work in collaboration with a large multistate gas utility. The project addressed a major operational resource allocation challenge that is typical to the industry. We ...
  • Demanet, Laurent; Ferrara, Matthew; Maxwell, Nicholas; Poulson, Jack; Ying, Lexing (SPIE - International Society for Optical Engineering, 2011-05)
    It is not currently known if it is possible to accurately form a synthetic aperture radar image from N data points in provable near-linear complexity, where accuracy is defined as the ℓ₂ error between the full O(N²) ...
  • Demanet, Laurent; Ferrara, Matthew; Maxwell, Nicholas; Poulson, Jack; Ying, Lexing (Society for Industrial and Applied Mathematics, 2012-02)
    In spite of an extensive literature on fast algorithms for synthetic aperture radar (SAR) imaging, it is not currently known if it is possible to accurately form an image from N data points in provable near-linear time ...
  • Zegras, P. Christopher; Lee, Jae Seung; Ben-Joseph, Eran (Sage Publications, 2012-01)
    This article analyses the travel behaviour, residential choices and related preferences of 55+ baby boomers in suburban Boston, USA, looking specifically at age-restricted neighbourhoods. For this highly auto-dependent ...
  • Shmakov, S.; Makarova, K. S.; Semenova, E.; Minakhin, L.; Severinov, K.; Koonin, E. V.; Regev, Aviv; Abudayyeh, Omar Osama; Gootenberg, Jonathan S; Konermann, Silvana M; Joung, Julia; Slaymaker, Ian; Cox, David Benjamin Turitz; Lander, Eric Steven; Zhang, Feng (American Association for the Advancement of Science (AAAS), 2016-08)
    The clustered regularly interspaced short palindromic repeat (CRISPR)–CRISPR-associated genes (Cas) adaptive immune system defends microbes against foreign genetic elements via DNA or RNA-DNA interference. We characterize ...
  • Tonegawa, Susumu; McHugh, Thomas J. (Wiley Blackwell, 2009-07)
    The acquisition of Pavlovian fear learning engages the hippocampus when the conditioned stimuli are multimodal or temporally isolated from the unconditioned stimuli. By subjecting CA3-NR1 KO mice to conditioning protocols ...
  • Zukerberg, Lawrence R; Patrick, Gentry N; Nikolic, Margareta; Humbert, Sandrine; Wu, Chin-Lee; Vidal, Marc; Van Etten, Richard A; Tsai, Li-Huei; Lanier, Lorene M.; Gertler, Frank (Elsevier, 2000-06)
    Cyclin-dependent kinase 5 (Cdk5) is a small serine/threonine kinase that plays a pivotal role during development of the CNS. Cables, a novel protein, interacts with Cdk5 in brain lysates. Cables also binds to and is a ...
  • Agrawal, Kunal; Fineman, Jeremy T.; Krage, Jordan; Leiserson, Charles E.; Toledo, Sivan (Association for Computing Machinery (ACM), 2012-06)
    This paper considers the problem of scheduling streaming applications on uniprocessors in order to minimize the number of cache-misses. Streaming applications are represented as a directed graph (or multigraph), where nodes ...
  • Mao, Yandong; Kohler, Eddie; Morris, Robert Tappan (Association for Computing Machinery (ACM), 2012-04)
    We present Masstree, a fast key-value database designed for SMP machines. Masstree keeps all data in memory. Its main data structure is a trie-like concatenation of B+-trees, each of which handles a fixed-length slice of ...
  • Brodal, Gerth Stolting; Demaine, Erik D.; Fineman, Jeremy T.; Iacono, John; Langerman, Stefan; Munro, J. Ian (Society for Industrial and Applied Mathematics, 2010-01)
    Several existing cache-oblivious dynamic dictionaries achieve O(logB N) (or slightly better O(logB N over M )) memory transfers per operation, where N is the number of items stored, M is the memory size, and B is ...
  • Niesen, Urs; Shah, Devavrat; Wornell, Gregory W. (Institute of Electrical and Electronics Engineers, 2009-08)
    We consider the problem of delivering content cached in a wireless network of n nodes randomly located on a square of area n. In the most general form, this can be analyzed by considering the 2[superscript n] timesn-dimensional ...
