    • Bending forces plastically deform growing bacterial cell walls 

      Amir, Ariel; Babaeipour, F.; McIntosh, D. B.; Nelson, David R.; Jun, Suckjoon (Proceedings of the National Academy of Sciences, 2014)
      Cell walls define a cell shape in bacteria. They are rigid to resist large internal pressures, but remarkably plastic to adapt to a wide range of external forces and geometric constraints. Currently, it is unknown how ...
    • Direct Graphene Growth on Insulator 

      Lippert, Gunther; Dabrowski, Jarek; Lemme, Max; Marcus, Charles Masamed; Seifarth, Olaf; Lupina, Grzegorz (Wiley, 2011)
      Fabrication of graphene devices is often hindered by incompatibility between the silicon technology and the methods of graphene growth. Exfoliation from graphite yields excellent films but is good mainly for research. ...
    • Effect of Succimer on Growth of Preschool Children with Moderate Blood Lead Levels. 

      Peterson, Karen E.; Salganik, Mikhail; Campbell, Carla; Rhoads, George G; Rubin, Judith; Berger, Omer; Ware, James H.; Rogan, Walter (2004)
      Growth deficits associated with lead exposure might be ameliorated by chelation. We examined the effect of succimer on growth in 780 children 12-33 months old who had blood lead levels of 20-44 microg/dL and were randomized ...
    • Fractionalization 

      Alesina, Alberto; Devleeschauwer, Arnaud; Easterly, William; Kurlat, Sergio; Wacziarg, Romain (Springer Verlag, 2003)
      We provide new measures of ethnic, linguistic, and religious fractionalization for about 190 countries. These measures are more comprehensive than those previously used in the economics literature and we compare our new ...
    • Income Distribution, Political Instability, and Investment 

      Alesina, Alberto; Perotti, Roberto (Elsevier, 1996)
      This paper successfully tests on a sample of 71 countries for the period 1960–85 the following hypotheses. Income inequality, by fuelling social discontent, increases sociopolitical instability. The latter, by creating ...
    • Optimal Capital Versus Labor Taxation with Innovation-Led Growth 

      Aghion, Philippe; Akcigit, Ufuk; Fernández-Villaverde, Jesús (National Bureau of Economic Research Inc, 2012)
      Chamley (1986) and Judd (1985) showed that, in a standard neoclassical growth model with capital accumulation and infinitely lived agents, either taxing or subsidizing capital cannot be optimal in the steady state. In this ...
    • A unifying modeling of plant shoot gravitropism with an explicit account of the effects of growth 

      Bastien, Renaud; Douady, Stéphane; Moulia, Bruno (Frontiers Media S.A., 2014)
      Gravitropism, the slow reorientation of plant growth in response to gravity, is a major determinant of the form and posture of land plants. Recently a universal model of shoot gravitropism, the AC model, was presented, in ...
    • When Does Domestic Saving Matter for Economic Growth? 

      Aghion, Philippe; Comin, Diego; Howitt, Peter (2006)
      Can a country grow faster by saving more? We address this question both theoretically and empirically. In our model, growth results from innovations that allow local sectors to catch up with the frontier technology. In ...
