    • 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 Supernova Progenitors in the Era of Untargeted Transient Searches 

      Sanders, Nathan Edward (2014-06-06)
      Core-collapse supernovae (SNe) are the highly energetic explosions of massive stars (> 8 solar masses) that are pervasive in their influence throughout astrophysics. They are the phenomenon with primary responsibility for ...
    • 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 ...
    • Coronal Holes 

      Cranmer, Steven R. (Springer International Publishing, 2009)
      Coronal holes are the darkest and least active regions of the Sun, as observed both on the solar disk and above the solar limb. Coronal holes are associated with rapidly expanding open magnetic fields and the acceleration ...
    • Coronary artery disease and the contours of pharmaceuticalization 

      Pollock, Anne; Jones, David Shumway (Elsevier BV, 2015)
      Coronary artery disease (CAD) has dominated mortality for most of the past century, not just in Europe and North America but worldwide. Treatments for CAD, both pharmaceutical and surgical, have become leading sectors of ...
    • Coronary CT Angiography Versus Standard Emergency Department Evaluation for Acute Chest Pain and Diabetic Patients: Is There Benefit With Early Coronary CT Angiography?: Results of the Randomized Comparative Effectiveness ROMICAT II Trial 

      Truong, Quynh A.; Schulman‐Marcus, Joshua; Zakroysky, Pearl; Chou, Eric T.; Nagurney, John T.; Fleg, Jerome L.; Schoenfeld, David A.; Udelson, James E.; Hoffmann, Udo; Woodard, Pamela K. (John Wiley and Sons Inc., 2016)
      Background: Cardiac computed tomography angiography (CCTA) reduces emergency department length of stay compared with standard evaluation in patients with low‐ and intermediate‐risk acute chest pain. Whether diabetic patients ...
    • Corporate Board Gender Diversity and Stock Performance: The Competence Gap or Institutional Investor Bias? 

      Dobbin, Frank; Jung, Jiwook (The North Carolina Law Review Association, 2011)
      Women now make up a sixth of corporate board members in the Fortune 500. Some scholars suggest that women board members boost financial performance, and thus stock price, by making boards more effective. Indeed, early ...
    • Corporate Financial Policy and Taxation in a Growing Economy 

      Feldstein, Martin; Green, Jerry; Sheshinski, Eytan (MIT Press, 1979)
    • Corporate Ownership Around the World 

      La Porta, Rafael; Lopez-De-Silanes, Florencio; Shleifer, Andrei (Wiley-Blackwell, 1999)
      We present data on ownership structures of large corporations in 27 wealthy economies, making an effort to identify ultimate controlling shareholders of these firms. We find that, except in economies with very good shareholder ...
    • Correct Audit Logging: Theory and Practice 

      Amir-Mohammadian, Sepehr; Chong, Stephen N; Skalka, Christian (Springer Berlin Heidelberg, 2016)
      Retrospective security has become increasingly important to the theory and practice of cyber security, with auditing a crucial component of it. However, in systems where auditing is used, programs are typically instrumented ...
    • Corrected placement of Mus-Rattus fossil calibration forces precision in the molecular tree of rodents 

      Kimura, Yuri; Hawkins, Melissa T. R.; McDonough, Molly M.; Jacobs, Louis L.; Flynn, Lawrence J. (Nature Publishing Group, 2015)
