    • Critical analysis of the charge-state dependence of the energy loss of channeled ions 

      Golovchenko, Jene Andrew; Cox, D. E.; Goland, A. N. (American Physical Society (APS), 1982)
      A critical analysis of channeled-ion energy-loss experiments is presented with the goal of commenting on the presence of the Barkas effect of Z31 corrections to the stopping power. Accurate charge-density values are obtained ...
    • A Critical Assessment of Theories of Strain Gradient Plasticity 

      Evans, Anthony G.; Hutchinson, John W. (Elsevier, 2009)
      Theories to extend plasticity to the micron scale have been in existence for over a decade, complemented by a growing body of experimental data. Here, materials and mechanics aspects of two prominent strain gradient theories ...
    • Critical Behavior of an Impurity at the Boson Superfluid–Mott-Insulator Transition 

      Whitsitt, Seth; Sachdev, Subir (American Physical Society (APS), 2017-11-15)
      We present a universal theory for the critical behavior of an impurity at the two-dimensional superfluid–Mott-insulator transition. Our analysis is motivated by a numerical study of the Bose-Hubbard model with an impurity ...
    • Critical Casimir Effect in Three-Dimensional Ising Systems: Measurements on Binary Wetting Films 

      Fukumo, Masafumi; Yano, Yohko F.; Pershan, Peter S. (American Physical Society, 2005)
      The critical Casimir force (CF) is observed in thin wetting films of a binary liquid mixture close to the liquid/vapor coexistence. X-ray reflectivity shows thickness (L) enhancement near the bulk consolute point. The ...
    • A Critical Evaluation of Cohesive Zone Models of Dynamic Fracture 

      Falk, Michael L.; Needleman, Alan; Rice, James R. (EDP Sciences, 2001)
      Finite element calculations of dynamic fracture based on embedding cohesive surfaces in a continuum indicate that the predictions are sensitive to the cohesive law used. Simulations were performed on a square block in plane ...
    • Critical Inquiries into Language Ideologies and Pedagogies in a Linguistically Diverse, Reform-Minded Urban Middle School 

      Abernethy, Frances Harrison (2022-05-12)
      Research underscores that hegemonic stances toward non-mainstream languages and language varieties are prevalent in the larger educational landscape and have potential to cause harm for linguistically diverse student ...
    • A Critical Look at the Embodied Cognition Hypothesis and a New Proposal for Grounding Conceptual Content 

      Mahon, Bradford; Caramazza, Alfonso (Elsevier, 2008)
      Many studies have demonstrated that the sensory and motor systems are activated during conceptual processing. Such results have been interpreted as indicating that concepts, and important aspects of cognition more broadly, ...
    • Critical minimum temperature limits xylogenesis and maintains treelines on the southeastern Tibetan Plateau 

      Li, Xiaoxiang; Liang, Eryuan; Gri?ar, Jozica; Rossi, Sergio; Cufar, Katarina; Ellison, Aaron M. (Elsevier BV, 2017)
      Physiological and ecological mechanisms that define treelines are still debated. It has been suggested that the absence of trees above the treeline is caused by low temperatures that limit growth. Thus, we hypothesized ...
    • Critical period plasticity and sensory function in a neuroligin-3 model of autism 

      LeBlanc, Jocelyn Jacqueline (2013-10-08)
      Extensive experience-dependent refinement of cortical circuits is restricted to critical periods of plasticity early in life. The timing of these critical periods is tightly regulated by the relative levels of excitatory ...
    • Critical Study: Cassam on Self-Knowledge for Humans 

      Boyle, Matthew (Wiley-Blackwell, 2015)
    • Critical temperature and precipitation thresholds for the onset of xylogenesis of Juniperus przewalskii in a semi-arid area of the north-eastern Tibetan Plateau 

      Ren, Ping; Rossi, Sergio; Camarero, J; Ellison, Aaron M.; Liang, Eryuan; Penuelas, Josep (Oxford University Press (OUP), 2017-12-29)
      Background and Aims The onset of xylogenesis plays an important role in tree growth and carbon sequestration, and it is thus a key variable to model the responses of forest ecosystems to climate change. Temperature regulates ...
    • CRKL Is an Important Regulator of PI3K Signaling in PTEN-Deficient Tumors 

      Zhang, Jing (2013-09-25)
      In response to signals mediated by receptor tyrosine kinases (RTKs), G protein-coupled receptors or oncogenes, the two ubiquitously expressed isoforms of class IA phosphatidylinositol-3-kinases (PI3Ks), \(p110\alpha\) and ...
    • The Cromwellian Protectorate and the Languages of Empire 

      Armitage, David (Cambridge University Press, 1992)
      This article recovers some of the classical, constitutional, and religious languages of empire in early-modern Britain by a consideration of the period between the end of the first Anglo-Dutch war in 1654 and the calling ...
    • Cross and Book: Late-Carolingian Breton Gospel Illumination and the Instrumental Cross 

      Kitzinger, Beatrice (2013-02-15)
      Crosses made in metal, paint, or stone stand at a singular intersection of past, present and future in the early medieval period. The historical cross of Golgotha is the source of such manufactured crosses’ form and power. ...
    • Cross Modulation of Two Laser Beams at the Individual-Photon Level 

      Beck, Kristin M.; Chen, Wenlan; Lin, Qian; Gullans, Michael; Lukin, Mikhail D.; Vuletić, Vladan (American Physical Society (APS), 2014)
      Deterministic photon-photon interactions are a long-standing goal in optical science. Using an atomic ensemble inside a cavity, we demonstrate the mutual cross modulation of two continuous light beams at the level of ...
