    • Consistency of spherical, gravity-dominated dynamics with quasar high-ionization emission-line profiles 

      Kallman, T. R.; Wilkes, Belinda Jane; Krolik, J. H.; Green, Richard (IOP Publishing, 1993)
      Line profile data are used to test a simple kinematic model - spherically symmetric gravitational free fall - in which the number of free parameters is limited by requiring physical self-consistency. The predictions of ...

    • Consistent Factor Estimation in Dynamic Factor Models with Structural Instability 

      Bates, Brandon J.; Plagborg-Møller, Mikkel; Stock, James H.; Watson, Mark W. (Elsevier BV, 2013)
      This paper considers the estimation of approximate dynamic factor models when there is temporal instability in the factor loadings. We characterize the type and magnitude of instabilities under which the principal components ...

    • Consistent scenarios for cosmic-ray excesses from Sommerfeld-enhanced dark matter annihilation 

      Finkbeiner, Douglas; Goodenough, Lisa; Slatyer, Tracy R; Vogelsberger, Mark; Weiner, Neal (IOP Publishing, 2011)
      Anomalies in direct and indirect detection have motivated models of dark matter consisting of a multiplet of nearly-degenerate states, coupled by a new GeV-scale interaction. We perform a careful analysis of the thermal ...

    • Consistent use of effective potentials 

      Andreassen, Anders Johan; Frost, William Thomas; Schwartz, Matthew D (American Physical Society (APS), 2015)
      It is well known that effective potentials can be gauge dependent while their values at extrema should be gauge invariant. Unfortunately, establishing this invariance in perturbation theory is not straightforward, since ...

    • Consistent Use of the Standard Model Effective Potential 

      Andreassen, Anders Johan; Frost, William Thomas; Schwartz, Matthew D (American Physical Society (APS), 2014)
      The stability of the Standard Model is determined by the true minimum of the effective Higgs potential. We show that the potential at its minimum when computed by the traditional method is strongly dependent on the gauge ...

    • Consonant Harmony in Karaim 

      Nevins, Andrew Ira; Vaux, Bert (Dept. of Linguistics and Philosophy, Massachusetts Institute of Technology, 2004)

    • Conspiracy, security, and human care in Donnersmarck's Liben der anderen. 

      Hamilton, John T. (GESIS, 2013)
      Florian Henckel von Donnersmarck's acclaimed film, Das Leben der Anderen (2006), affords a provocative opportunity for investigating the relation between conspiracy and security. Although state-sponsored onspiracies breed ...

    • Constant Growth Rate Can Be Supported by Decreasing Energy Flux and Increasing Aerobic Glycolysis 

      Slavov, Nikolai; Budnik, Bogdan; Schwab, David; Airoldi, Edoardo Maria; van Oudenaarden, Alexander (Elsevier BV, 2014)
      Fermenting glucose in the presence of enough oxygen to support respiration, known as aerobic glycolysis, is believed to maximize growth rate. We observed increasing aerobic glycolysis during exponential growth, suggesting ...

    • The constant inner-disk radius of LMC X-3: A basis for measuring black hole spin 

      Steiner, James; McClintock, Jeffrey E.; Remillard, Ronald A.; Gou, Lijun; Yamada, Shin; Narayan, Ramesh (IOP Publishing, 2010)
      he black hole binary system LMC X-3 has been observed by virtually every X-ray mission since the inception of X-ray astronomy. Among the persistent sources, LMC X-3 is uniquely both habitually soft and highly variable. ...

    • Constant rate of p53 tetramerization in response to DNA damage controls the p53 response 

      Gaglia, Giorgio; Lahav, Galit (BlackWell Publishing Ltd, 2014)
      The dynamics of the tumor suppressor protein p53 have been previously investigated in single cells using fluorescently tagged p53. Such approach reports on the total abundance of p53 but does not provide a measure for ...

    • A Constant Recontracting Model of Sovereign Debt 

      Bulow, Jeremy; Rogoff, Kenneth S. (University of Chicago Press, 1989)
      We present a dynamic model of international lending in which borrowers cannot commit to future repayments and in which debtors can sometimes successfully negotiate partial defaults or "rescheduling agreements." All parties ...

    • Constituency Service and Incumbency Advantage 

      King, Gary (Cambridge University Press, 1991)
      Numerous scholars have documented a dramatic increase in incumbency advantage in US congressional elections and also state legislative elections over the past four decades. For example, Gelman and King show that incumbents ...

    • Constituents' responses to congressional roll call voting 

      Ansolabehere, Stephen Daniel; Jones, Philip Edward (Wiley-Blackwell, 2010)
      Do citizens hold their representatives accountable for policy decisions, as commonly assumed in theories of legislative politics? Previous research has failed to yield clear evidence on this question for two reasons: ...

    • Constitution of Antheridium-Inducing Factor of Anemia Phyllitidis 

      Corey, E. J.; Myers, Andrew G.; Takahashi, Nobutaka; Yamane, Hisakazu; Schraudolf, Helmut (Elsevier, 1986)
      Careful comparison of naturally derived and synthetic samples of the antheridium-inducing factor of Anemia phyllitidis, AA,,, by TLC, HPLC, NMR and GC-MS measurements allow unambiguous assignment of structure 2 to this ...

    • Constitutional Character: Virtues and Vices in Presidential Leadership 

      Thompson, Dennis F. (Wiley-Blackwell, 2010)
      Presidents and presidential candidates should be assessed more than they usually are on the basis of what may be called constitutional character. This refers to the disposition to act, and motivate others to act, according ...

    • Constitutionalizing a Democratic Muslim State without Shari'a: The Religious Establishment in the Tunisian 2014 Constitution 

      Zeghal, Malika (Indiana University Press, 2016)

    • A constitutive description of the anisotropic response of the fascia lata 

      Pancheri, F.Q.; Eng, C.M.; Lieberman, Daniel E.; Biewener, Andrew Austin; Dorfmann, L. (Elsevier BV, 2014)
      In this paper we propose a constitutive model to analyze in-plane extension of goat fascia lata. We first perform a histological analysis of the fascia that shows a well-organized bi-layered arrangement of undulated collagen ...

    • Constitutivism and the virtues 

      Korsgaard, Christine (Informa UK Limited, 2019-04-05)
      In Self-Constitution, I argue that the principles governing action are “constitutive standards” of agency, standards that arise from the nature of agency itself. To be an agent is to be autonomously efficacious, and the ...

    • Constraining Alternate Models of Black Holes: Type I X‐Ray Bursts on Accreting Fermion‐Fermion and Boson‐Fermion Stars 

      Yuan, Ye-Fei; Narayan, Ramesh; Rees, Martin J. (American Astronomical Society, 2004)
      The existence of black holes remains open to doubt until other conceivable options are excluded. With this motivation, we consider a model of a compact star in which most of the mass consists of dark particles of some kind ...

    • Constraining Cosmological Parameters Based on Relative Galaxy Ages 

      Jimenez, Raul; Loeb, Abraham (American Astronomical Society, 2002)
      We propose to use relative galaxy ages as a means of constraining cosmological parameters. By measuring the age difference between two ensembles of passively evolving galaxies at somewhat different redshifts, one could ...
