    • Coordination of Flagella on Filamentous Cells of Escherichia Coli 

      Ishihara, Akira; Segall, Jeffrey E.; Block, Steven M.; Berg, Howard Curtis (American Society for Microbiology, 1983)
      Video techniques were used to study the coordination of different flagella on single filamentous cells of Escherichia coli. Filamentous, nonseptate cells were produced by introducing a cell division mutation into a strain ...
    • Coordination of Growth Rate, Cell Cycle, Stress Response, and Metabolic Activity in Yeast 

      Brauer, M. J.; Huttenhower, Curtis; Airoldi, Edoardo Maria; Rosenstein, R.; Matese, J. C.; Gresham, D.; Boer, V. M.; Troyanskaya, O. G.; Botstein, D. (American Society for Cell Biology (ASCB), 2008)
      We studied the relationship between growth rate and genome-wide gene expression, cell cycle progression, and glucose metabolism in 36 steady-state continuous cultures limited by one of six different nutrients (glucose, ...
    • Cophylogeny and Biogeography of the Fungal Parasite Cyttaria and Its Host Nothofagus, Southern Beech 

      Peterson, Kristin R.; Pfister, Donald H.; Bell, Charles D. (Mycological Society of America, 2010)
      The obligate, biotrophic association among species of the fungal genus Cyttaria and their hosts in the plant genus Nothofagus often is cited as a classic example of cophylogeny and is one of the few cases in which the ...
    • Copper-Mediated Amidation of Heterocyclic and Aromatic C−H Bonds 

      Wang, Qiu; Schreiber, Stuart L. (American Chemical Society, 2009)
      A copper-mediated aerobic coupling reaction enables direct amidation of heterocycles or aromatics having weakly acidic C−H bonds with a variety of nitrogen nucleophiles. These reactions provide efficient access to many ...
    • Cordelia's Love: Credibility and the Social Studies of Science 

      Shapin, Steven (The University of Chicago Press, 1995)
      This article assesses the current state of research on the credibility of scientific claims and makes some recommendations about the lines along which future historical and sociological inquiry might most constructively ...
    • The Core Apoptotic Executioner Proteins CED-3 and CED-4 Promote Initiation of Neuronal Regeneration in Caenorhabditis elegans 

      Pinan-Lucarre, Berangere; Gabel, Christopher V.; Reina, Christopher P.; Hulme, S. Elizabeth; Shevkoplyas, Sergey S.; Slone, R. Daniel; Xue, Jian; Qiao, Yujie; Weisberg, Sarah; Roodhouse, Kevin; Whitesides, George M.; Samuel, Aravinthan DT; Driscoll, Monica (Public Library of Science, 2012)
      A critical accomplishment in the rapidly developing field of regenerative medicine will be the ability to foster repair of neurons severed by injury, disease, or microsurgery. In C. elegans, individual visualized axons ...
    • The Core Apoptotic Executioner Proteins CED-3 and CED-4 Promote Neuronal Regeneration in Caenorhabditis Elegans 

      Pinan-Lucarre, Berangere; Gabel, Christopher V.; Reina, Christopher P.; Hulme, S. Elizabeth; Shevkopylas, Sergey S.; Slone, R. Daniel; Xue, Jian; Qiao, Yujie; Weisberg, Sarah; Roodhouse, Kevin; Sun, Lin; Whitesides, George M.; Samuel, Aravinthan DT; Drisocll, Monica (Public Library of Science, 2012)
      A critical accomplishment in the rapidly developing field of regenerative medicine will be the ability to foster repair of neurons severed by injury, disease, or microsurgery. In C. elegans, individual visualized axons can ...
    • Core foundations of abstract geometry 

      Dillon, Moira Rose; Huang, Y.; Spelke, Elizabeth S. (Proceedings of the National Academy of Sciences, 2013)
      Human adults from diverse cultures share intuitions about the points, lines, and figures of Euclidean geometry. Do children develop these intuitions by drawing on phylogenetically ancient and developmentally precocious ...
    • Core knowledge and its limits: The domain of food 

      Shutts, Kristin Beth; Condry, Kirsten F.; Santos, Laurie R.; Spelke, Elizabeth S. (Elsevier BV, 2009)
      Adults, preschool children, and nonhuman primates detect and categorize food objects according to substance information, conveyed primarily by color and texture. In contrast, they perceive and categorize artifacts primarily ...
    • Core Knowledge and the Emergence of Symbols: The Case of Maps 

      Huang, Yi; Spelke, Elizabeth S. (Informa UK Limited, 2014)
      Map reading is unique to humans but is present in people of diverse cultures, at ages as young as 4 years old. Here, we explore the nature and sources of this ability and ask both what geometric information young children ...
    • Core Multiplication in Childhood 

      McCrink, Koleen; Spelke, Elizabeth S. (Elsevier, 2010)
      A dedicated, non-symbolic, system yielding imprecise representations of large quantities (approximate number system, or ANS) has been shown to support arithmetic calculations of addition and subtraction. In the present ...
    • Core Social Cognition 

      Spelke, Elizabeth S.; Bernier, Emily Pantaleoni; Skerry, Amy (Oxford University Press, 2013)
      Research on human infants and young children has provided evidence for five systems of core knowledge: knowledge of objects and their motions; of agents and their goal-directed actions; of number and the operations of ...
    • Core-collapse Supernovae and Host Galaxy Stellar Populations 

      Kelly, Patrick L.; Kirshner, Robert P. (American Astronomical Society, 2012)
      We have used images and spectra of the Sloan Digital Sky Survey to examine the host galaxies of 519 nearby supernovae (SN). The colors at the sites of the explosions, as well as chemical abundances, and specific star ...
    • Cores in Dwarf Galaxies from Dark Matter with a Yukawa Potential 

      Loeb, Abraham; Weiner, Neal (American Physical Society, 2011)
      We show that cold dark matter particles interacting through a Yukawa potential could naturally explain the recently observed cores in dwarf galaxies without affecting the dynamics of objects with a much larger velocity ...
    • CoREST is an integral component of the CoREST- human histone deacetylase complex 

      You, Angie; Tong, Jeffrey K.; Grozinger, Christina M.; Schreiber, Stuart L. (National Academy of Sciences, 2001)
      Here we describe the components of a histone deacetylase (HDAC) complex that we term the CoREST-HDAC complex. CoREST-HDAC is composed of polypeptides distinct from previously characterized HDAC1/2-containing complexes such ...
    • Core–shell colloidal particles with dynamically tunable scattering properties 

      Meng, Guangnan; Manoharan, Vinothan N.; Perro, Adeline (Royal Society of Chemistry (RSC), 2017)
      We design polystyrene–poly(N′-isopropylacrylamide-co-acrylic acid) core–shell particles that exhibit dynamically tunable scattering. We show that under normal solvent conditions the shell is nearly index-matched to pure ...
    • A Corollary of the B-function Lemma 

      Beilinson, Alexander; Gaitsgory, Dennis (Birkhäuser Basel, 2011)
      Let \(X\) be an algebraic variety, \(f\) a regular function, \(j:U \hookrightarrow X\) the complement to the locus of vanishing of \(f\), and \(M\) a holonomic D-module on \(U\). Consider the \(D_U[s]\)-module \(M\otimes ...
    • CORONA Satellite Photography and Ancient Road Networks: A Northern Mesopotamian Case Study 

      Ur, Jason Alik (Antiquity Publications, 2003)
      Landscape archaeology has emphasised the role of the entire landscape in ancient life, rather than putting an exclusive focus on those loci of intensive behaviour we call “sites.” The broader area of interest requires a ...
