  • Jung, Heekyung; Lacombe, Julie; Mazzoni, Esteban O.; Liem, Karel F., Jr.; Grinstein, Jonathan; Mahony, Shaun; Mukhopadhyay, Debnath; Gifford, David K.; Young, Richard A. (Elsevier, 2010-09)
    In the developing spinal cord, regional and combinatorial activities of Hox transcription factors are critical in controlling motor neuron fates along the rostrocaudal axis, exemplified by the precise pattern of limb ...
  • Slotine, Jean-Jacques E.; Russo, Giovanni (American Physical Society, 2010-10)
    In many natural synchronization phenomena, communication between individual elements occurs not directly but rather through the environment. One of these instances is bacterial quorum sensing, where bacteria release signaling ...
  • Van Damme, M.; Clarisse, L.; Hurtmans, D. R.; Ngadi, Y.; Clerbaux, C.; Dolman, A. J.; Erisman, J. W.; Coheur, P. -F.; Heald, Colette L. (Copernicus GmbH, 2014-03)
    Ammonia (NH[subscript 3]) emissions in the atmosphere have increased substantially over the past decades, largely because of intensive livestock production and use of fertilizers. As a short-lived species, NH[subscript 3] ...
  • Ivy, Diane J.; Rigby, Matthew; Baasandorj, M.; Burkholder, J. B.; Prinn, Ronald G. (Copernicus GmbH, 2012-08)
    Global emission estimates based on new atmospheric observations are presented for the acylic high molecular weight perfluorocarbons (PFCs): decafluorobutane (C[subscript 4]F[subscript 10]), dodecafluoropentane (C[subscript ...

    HCFC-22 (CHClF[subscript 2]) and HFC-134a (CH[subscript 2]FCF[subscript 3]) are two major gases currently used worldwide in domestic and commercial refrigeration and air conditioning. HCFC-22 contributes to stratospheric ...
  • Nikurashin, Maxim Anatolevich; Ferrari, Raffaele (American Geophysical Union (AGU), 2011-04)
    A global estimate of the energy conversion rate from geostrophic flows into internal lee waves in the ocean is presented. The estimate is based on a linear theory applied to bottom topography at O(1–10) km scales obtained ...
  • Ploegh, Hidde; Yuan, Bingbing B.; Carette, Jan E.; Guimaraes, Carla P.; Wuethrich, Irene; Blomen, Vincent A.; Varadarajan, Malini; Sun, Chong; Bell, George W.; Muellner, Markus K.; Nijman, Sebastian M.; Brummelkamp, Thijn R. (Nature Publishing Group, 2011-05)
    Insertional mutagenesis in a haploid background can disrupt gene function[superscript 1]. We extend our earlier work by using a retroviral gene-trap vector to generate insertions in >98% of the genes expressed in a human ...
  • Wunsch, Carl; Heimbach, Patrick; Ponte, Rui M.; Fukumori, Ichiro; ECCO-GODAE Consortium (Oceanography Society (Virginia Beach, Va.), 2009-06)
    Following on the heels of the World Ocean Circulation Experiment, the Estimating the Circulation and Climate of the Ocean (ECCO) consortium has been directed at making the best possible estimates of ocean circulation ...
  • Chirkov, M.; Stiller, G. P.; Laeng, A.; Kellmann, S.; von Clarmann, T.; Boone, C. D.; Elkins, J. W.; Engel, A.; Glatthor, N.; Grabowski, U.; Harth, C. M.; Kiefer, M.; Kolonjari, F.; Krummel, P.

(Copernicus GmbH, 2016-03)
    We report on HCFC-22 data acquired by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) in the reduced spectral resolution nominal observation mode. The data cover the period from January 2005 to April ...
  • Selin, Noelle Eckley; Wu, S.; Nam, Kyung-min; Reilly, J. M.; Paltsev, Sergey; Prinn, Ronald G.; Webster, Mort David (Institute of Physics Publishing, 2009-12)
    We assess the human health and economic impacts of projected 2000–2050 changes in ozone pollution using the MIT Emissions Prediction and Policy Analysis - Health Effects (EPPA-HE) model, in combination with results from ...
  • Caballero, Ricardo J.; Krishnamurthy, Arvind (American Economic Association, 2009-05)
    The United States is currently engulfed in the most severe financial crisis since the Great Depression. The crisis was triggered by the crash in the real estate “bubble” and amplified by the extreme concentration of ...
  • Lohmeyer, Whitney Quinne; Dwyer, Morgan; Gettliffe, Gwendolyn Vines; Marinan, Anne D.; Stockham, Erik; Weigel, Annalisa L.; Cahoy, Kerri; Alibay, Farah (International Astronautical Federation, 2012-10)
    Under the United States Arms Export Control Act, the International Traffic in Arms Regulations (ITAR) control the export of technologies that are specified as defense articles on the United States Munitions List (USML). ...
  • Mazlish, Bruce (Berkeley Electronic Press, 2009-11)
    Globalism and globalization have been seen as competitors to other allegiances, namely regionalism and nationalism. A look at recent efforts at reconceptualizing global history in China, Korea and the U.S., however, suggests ...
  • Koldewyn, Kami; Jiang, Yuhong V.; Weigelt, Sarah; Kanwisher, Nancy (Springer-Verlag, 2013-02)
    It is widely suggested that ASD is characterized by atypical local/global processing, but the published findings are contradictory. In an effort to resolve this question, we tested a large group of children on both a ...
  • Gurbuzbalaban, Mert; Ozdaglar, Asuman E.; Parrilo, Pablo A. (Springer-Verlag, 2015-04)
    Motivated by machine learning problems over large data sets and distributed optimization over networks, we develop and analyze a new method called incremental Newton method for minimizing the sum of a large number of ...
  • Chen, Sidi; Xue, Yuan; Wu, Xuebing; Le, Cong; Bhutkar, Arjun (AJ); Bell, Eric L.; Zhang, Feng; Langer, Robert; Sharp, Phillip A.; Wu, Xuebing (Cold Spring Harbor Laboratory Press, 2014-05)
    MicroRNAs delicately regulate the balance of angiogenesis. Here we show that depletion of all microRNAs suppresses tumor angiogenesis. We generated microRNA-deficient tumors by knocking out Dicer1. These tumors are highly ...
  • Chen, Harr; Branavan, Satchuthanan R.; Barzilay, Regina; Karger, David R. (Association for Computational Linguistics, 2009-06)
    We present a novel Bayesian topic model for learning discourse-level document structure. Our model leverages insights from discourse theory to constrain latent topic assignments in a way that reflects the underlying ...
  • Britter, Rex E.; Waitz, Ian A.; Barrett, Steven (American Chemical Society (ACS), 2010-10)
    Aircraft emissions impact human health though degradation of air quality. The majority of previous analyses of air quality impacts from aviation have considered only landing and takeoff emissions. We show that aircraft ...
  • Poliannikov, Oleg V.; Zhizhina, Elena; Krim, Hamid (Institute of Electrical and Electronics Engineers, 2010-12)
    In this paper, we study a diffusion stochastic dynamics with a general diffusion coefficient. The main result is that adapting the diffusion coefficient to the Hamiltonian allows to escape local wide minima and to speed ...
  • Ghebrebrhan, Michael; Bermel, Peter A.; Joannopoulos, John D.; Johnson, Steven G.; Avniel, Yehuda B. (Optical Society of America, 2009-04)
    The front-coating (FC) of a solar cell controls its efficiency, determining admission of light into the absorbing material and potentially trapping light to enhance thin absorbers. Single-layer FC designs are well known, ...
