      Krieger, Teresa; Simons, Benjamin D. (Company of Biologists, 2015-04-15)
      Recent lineage-tracing studies based on inducible genetic labelling have emphasized a crucial role for stochasticity in the maintenance and regeneration of cycling adult tissues. These studies have revealed that stem ...
    • Dynamic systems approaches and levels of analysis in the nervous system 

      Parker, David; Srivastava, Vipin (Frontiers, 2013-02-05)
      Various analyses are applied to physiological signals. While epistemological diversity is necessary to address effects at different levels, there is often a sense of competition between analyses rather than integration. ...

      We give a general method to find exact cosmological solutions for scalar-field dark energy in the presence of perfect fluids. We use the existence of invariant transformations for the Wheeler De Witt (WdW) equation. We ...
    • Dynamical properties of two- and three-dimensional colloidal clusters of six particles 

      Fačkovec, Boris; Morgan, John William Roger; Wales, David J. (Royal Society of Chemistry, 2016-03-14)
      Colloidal clusters are important systems for studying self-assembly. Clusters of six colloidal particles attracting each other via short-ranged interactions have been recently studied both theoretically and experimentally. ...
    • Dynamically Controlled Iridescence of Cholesteric Cellulose Nanocrystal Suspensions Using Electric Fields 

      Frka-Petesic, B; Radavidson, H; Jean, B; Heux, L (Wiley, 2017-01-01)
      Cellulose nanocrystal suspensions in apolar solvent spontaneously form iridescent liquid crystalline phases but the control of their macroscopic order is usually poor. The use of electric fields can provide control on the ...
    • Dynamics of a Molecular Glass Former: Energy Landscapes for Diffusion in Ortho-Terphenyl 

      Niblett, S. P.; de Souza, V. K.; Stevenson, J. D.; Wales, D. J. (American Institute of Physics Publishing, 2016-07-13)
      Relaxation times and transport processes of many glass-forming supercooled liquids exhibit a super-Arrhenius temperature dependence. We examine this phenomenon by computer simulation of the Lewis-Wahnstrom model for ...
