Folding in the Greenland Ice Sheet
Journal of Geophysical Research: Solid Earth, 1987The deformation of layering into folds is modeled for a linear viscous medium moving over a décollement. Folds are generated by flow variations caused by relief on the décollement, variations in friction, or both. The model is applied to folds forming now in the Greenland Ice Sheet near Dye 3, for which more complete data are available than for ...

Folding of viscous sheets and filaments
Europhysics Letters (EPL), 2000We consider the nonlinear folding behavior of a viscous filament or a sheet under the influence of an external force such as gravity. Everyday examples of this phenomenon are provided by the periodic folding of a sheet of honey as it impinges on toast, or the folding of a stream of shampoo as it falls on one's hand.

The folding mechanism of a β-sheet: the WW domain
Journal of Molecular Biology, 2001The folding thermodynamics and kinetics of the Pin WW domain, a three-stranded antiparallel beta-sheet, have been characterized extensively. Folding and activation free energies were determined as a function of temperature for 16 mutants, which sample all strands and turns of the molecule.

Scaling properties of randomly folded plastic sheets
Physical Review E, 2007We study the scaling properties of randomly folded aluminum sheets of different thicknesses h and widths L . We found that the fractal dimension D=2.30+/-0.01 and the force scaling exponent delta=0.21+/-0.02 are independent of the sheet thickness and close to those obtained in numerical simulations with a coarse-grained model of triangulated self ...

Kinetic studies of β-sheet protein folding
Current Opinion in Structural Biology, 1998New studies have shown that folding of beta-sheet proteins can occur with and without intermediates, with fast to slow refolding rates and late to very late transition states. These experiments demonstrate that, despite early speculation to the contrary, beta-sheet protein folding does not appear to be fundamentally different from that of helical and ...

A continuous folding process for sheet materials
International Journal of Materials and Product Technology, 2004In this paper, we present a new and innovative sheet material folding technology and the associated advances in folding different patterns using continuous manufacturing techniques. A novel approach is developed for the continuous folding process where sheet material is progressively folded in two dimensions, through a set of rollers, followed by a ...

Protein Folding and β‐Sheet Proteins
Journal of the Chinese Chemical Society, 2000AbstractThe aim of this comprehensive review is to critically evaluate the progress in research in the area of protein folding. In the first section, we discuss the various models proposed to explain the protein folding paradox. In the succeeding section of the review, a detailed account of the developments in our understanding of the folding path ways

Folding of beta-sheet proteins.
Current opinion in structural biology, 1996In the past year, interesting new information concerning various aspects of the folding process of beta-sheet proteins has been gleaned. Kinetic and equilibrium folding intermediates have been characterized. Studies of extensively denatured states and of model peptide fragments have enabled important steps to be taken towards an understanding of the ...
