Tip Splittings and Phase Transitions in the Dielectric Breakdown Model: Mapping to the DLA Model
Joachim Mathiesen, Mogens H. Jensen
We show that the fractal growth described by the dielectric breakdown model exhibits a phase transition in the multifractal spectrum of the growth measure. The transition takes pla…
Parametrization of Multiple Pathways in Proteins: Fast Folding versus Tight Transitions
Paul G. Dommersnes, Alex Hansen, Mogens H. Jensen +1
Growing experimental evidence shows that proteins follow one or a few distinct paths when folding. We propose in this paper a procedure to parametrize these observed pathways, and…
Pathways in Two-State Protein Folding
Audun Bakk, Johan S. Hoye, Alex Hansen +2
The thermodynamics of proteins indicate that folding/unfolding takes place either through stable intermediates or through a two-state process without intermediates. The rather shor…
A Model for the Thermodynamics of Globular Proteins
Alex Hansen, Mogens H. Jensen, Kim Sneppen +1
Comments: 6 pages RevTeX, 6 Postscript figures. We review a statistical mechanics treatment of the stability of globular proteins based on a simple model Hamiltonian taking into ac…
Modelling Molecular Motors as Folding-Unfolding Cycles
Alex Hansen, Mogens H. Jensen, Kim Sneppen +1
We propose a model for motor proteins based on a hierarchical Hamiltonian that we have previously introduced to describe protein folding. The proposed motor model has high efficien…
Statistical mechanics of warm and cold unfolding in proteins
Alex Hansen, Mogens H. Jensen, Kim Sneppen +1
We present a statistical mechanics treatment of the stability of globular proteins which takes explicitly into account the coupling between the protein and water degrees of freedom…
A hierarchical scheme for cooperativity and folding in proteins
Alex Hansen, Mogens H. Jensen, Kim Sneppen +1
We propose a protein model based on a hierarchy of constraints that force the protein to follow certain pathways when changing conformation. The model exhibits a first order phase…
Morphological Instabilities in a growing Yeast Colony: Experiment and Theory
Thomas Sams, Kim Sneppen, Mogens H. Jensen +2
We study the growth of colonies of the yeast Pichia membranaefaciens on agarose film. The growth conditions are controlled in a setup where nutrients are supplied through an agaros…
