The old and the new: the evolution of polymer and biomedical clusters in Ohio and Sweden

Johansson, Dan; Cetindamar, Dilek; Carlsson, Bo; … - In: Journal of Evolutionary Economics 10 (2000) 5, pp. 471-488

This paper examines the rapid growth of the polymer-based and biomedical clusters in Ohio and Sweden - two regions of similar size and with similar traditions undergoing similar industrial restructuring. <p>Two issues are addressed: First, why has growth been so strong in these particular clusters,...</p>

Anisotropic dynamic response of pentacene single crystals

Schuster, R.; Knupfer, M.; Zahn, D. R.T.; Berger, H. - In: The European Physical Journal B - Condensed Matter and … 59 (2007) 1, pp. 25-28

We have investigated the polarization and momentum dependence of singlet excitons in pentacene molecular crystals using inelastic electron scattering. Our results demonstrate that both the direction as well as the absolute value of the momentum are decisive for the spectral intensity of these...

Turbulent drag reduction in one and two dimensions

Odijk, Theo - In: Physica A: Statistical Mechanics and its Applications 298 (2001) 1, pp. 140-154

Drag reduction is investigated in one- and two-dimensional turbulent flows that are stationary and homogeneous. In the two-dimensional case, the polymer chains are deformed though advected passively through the Kraichnan cascades within a scaling analysis. The typical rate of shear must then be...

Dynamics of linear polymers in random media

Chakrabarti, Bikas K.; Chattopadhyay, Amit K.; Dutta, Amit - In: Physica A: Statistical Mechanics and its Applications 333 (2004) C, pp. 34-40

We study phenomenological scaling theories of the polymer dynamics in random media, employing the existing scaling theories of polymer chains and the percolation statistics. We investigate both the Rouse and the Zimm model for Brownian dynamics and estimate the diffusion constant of the...
