    • Charles Darwin and ideology: Rethinking the Darwinian revolution 

      Browne, Janet E (Universitat de Valencia, 2016)
      This short paper critiques the idea of any coherent Darwinian ideology. Charles Darwin himself did not adopt any obvious ideology, except perhaps that of anti-slavery. However, his published work, and that of other ...
    • Charles Darwin as a Celebrity 

      Browne, Janet E (Cambridge University Press, 2003)
      Several recent works in sociology examine the manufacture of public identities through the notion of celebrity. This paper explores the imagery of Charles Darwin as a nineteenth-century scientific celebrity by comparing ...

      Browne, Janet E (W.H. Freeman, 2011)
    • Charles LeDray

    • The Charmed Life of Superstar Exporters: Survey Evidence on Firms and Trade Policy 

      Osgood, Iain; Tingley, Dustin; Bernauer, Thomas; Kim, In Song; Milner, Helen V.; Spilker, Gabriele (University of Chicago Press, 2017-01)
      What factors determine firms' attitudes toward trade policy? This paper considers producers' policy preferences and political behavior in light of two key patterns in modern international trade: industries that face import ...
    • Charming CP violation and dipole operators from RS flavor anarchy 

      Delaunay, Cédric; Kamenik, Jernej F.; Perez, Gilad; Randall, Lisa (Springer Verlag, 2013)
      Recently the LHCb collaboration reported evidence for direct CP violation in charm decays. The value is sufficiently large that either substantially enhanced Standard Model contributions or non-Standard Model physics is ...
    • Charting a dynamic DNA methylation landscape of the human genome 

      Ziller, Michael J.; Gu, Hongcang; Müller, Fabian; Donaghey, Julie; Tsai, Linus T.-Y.; Kohlbacher, Oliver; De Jager, Phil L.; Rosen, Evan D.; Bennett, David A.; Bernstein, Bradley E.; Gnirke, Andreas; Meissner, Alexander (2013)
      DNA methylation is a defining feature of mammalian cellular identity and essential for normal development1,2. Most cell types, except germ cells and pre-implantation embryos3–5, display relatively stable DNA methylation ...
    • Charting Cellular Identity During Human in Vitro β-Cell Differentiation 

      Veres, Adrian; Faust, Aubrey; Bushnell, Henry; Engquist, Elise; Kenty, Jennifer; Harb, George; Poh, Yeh-Chuin; Sintov, Elad; Gürtler, Mads; Pagliuca, Felicia; Peterson, Quinn; Melton, Douglas (Springer Science and Business Media LLC, 2019-05)
      In vitro differentiation of human stem cells can produce pancreatic β-cells; the loss of this insulin-secreting cell type underlies type 1 diabetes. Here, as a step towards understanding this differentiation process, we ...
    • Chasing Noise 

      Mendel, Brock; Shleifer, Andrei (Elsevier, 2012)
      We present a simple model in which rational but uninformed traders occasionally chase noise as if it were information, thereby amplifying sentiment shocks and moving prices away from fundamental values. In the model, noise ...
    • Chasing the Identification of ASCA Galactic Objects (ChIcAGO) - An X-ray Survey of Unidentified Sources in the Galactic Plane I: Source Sample and Initial Results 

      Anderson, Gemma E.; Gaensler, B. M.; Kaplan, David L.; Slane, Patrick O.; Muno, Michael P.; Posselt, Bettina; Hong, Jaesub; Murray, Stephen S.; Steeghs, Danny T. H.; Brogan, Crystal L.; Drake, Jeremy J.; Farrell, Sean A.; Benjamin, Robert A.; Chakrabarty, Deepto; Drew, Janet E.; Finley, John P.; Grindlay, Jonathan E.; Lazio, T. Joseph W.; Lee, Julia C.; Mauerhan, Jon C.; van Kerkwijk, Marten H. (IOP Publishing, 2014)
      We present the Chasing the Identification of ASCA Galactic Objects (ChIcAGO) survey, which is designed to identify the unknown X-ray sources discovered during the ASCA Galactic Plane Survey (AGPS). Little is known about ...
    • Checking Polynomial Identities over any Field: Towards a Derandomization? 

      Lewin, Daniel; Vadhan, Salil P. (Association of Computing Machinery, 1998)
      We present a Monte Carlo algorithm for testing multivariate polynomial identities over any field using fewer random bits than other methods. To test if a polynomial \(P(x_1, ..., x_n)\) is zero, our method uses \(\sum_{i=1}^n ...
    • Checkpoint kinase 1 (Chk1) is required for mitotic progression through negative regulation of polo-like kinase 1 (Plk1) 

      Tang, Jiabin; Erikson, Raymond L.; Liu, Xiaoqi (National Academy of Sciences, 2006)
      Although the essential function of checkpoint kinase 1 (Chk1) in DNA damage response has been well established, the role of Chk1 in normal cell cycle progression is unclear. By using RNAi to specifically deplete Chk1, we ...
