Statistical multifragmentation of nuclei

…, AS Botvina, AS Iljinov, IN Mishustin, K Sneppen - Physics Reports, 1995 - Elsevier
This review is devoted to the Statistical Multifragmentation Model (SMFM) developed in
Copenhagen more than 10 years ago and widely used now for interpreting experimental data on …

Simplified models of biological networks

K Sneppen, S Krishna, S Semsey - Annual review of biophysics, 2010 - annualreviews.org
… As before, for the feedback to have a chance of working, the parameters should satisfy τ L
·c L >K L and τ R ·c R >K R . This system is bistable when (a) c L ·τ L /K L and c R ·τ R /K R are …

Punctuated equilibrium and criticality in a simple model of evolution

P Bak, K Sneppen - Physical review letters, 1993 - APS
… Following Sneppen and Jensen [10] we then measure the distribution, C(x), of the distance
… The exponent appears to be the same as the one studied in a stringmodel by Sneppen and …

Oscillations and temporal signalling in cells

…, S Krishna, S Pigolotti, MH Jensen, K Sneppen - Physical …, 2007 - iopscience.iop.org
The development of new techniques to quantitatively measure gene expression in cells has
shed light on a number of systems that display oscillations in protein concentration. Here we …

Detection of topological patterns in complex networks: correlation profile of the internet

S Maslov, K Sneppen, A Zaliznyak - Physica A: Statistical Mechanics and its …, 2004 - Elsevier
… P(K 1 |K 0 ) crosses over from K 1 /K 1 γ for K 1 ⪡K 1 ∗ =2E/K 0 to 1/K 1 γ power law tail for K
1 ⪢K 1 ∗ … Such a crossover results in an asymptotic scaling <K 1 > K 0 ∼K 0 γ−3 . We have …

[HTML][HTML] Theoretical analysis of epigenetic cell memory by nucleosome modification

IB Dodd, MA Micheelsen, K Sneppen, G Thon - Cell, 2007 - cell.com
Chromosomal regions can adopt stable and heritable alternative states resulting in bistable
gene expression without changes to the DNA sequence. Such epigenetic control is often …

Statistical simulation of the break-up of highly excited nuclei

…, IN Mishustin, JP Bondorf, R Donangelo, K Sneppen - Nuclear Physics A, 1987 - Elsevier
We employ a model of multifragmentation of highly excited nuclei based on the statistical
approach and a liquid-drop description of hot fragments. We consider the principal equations of …

Evolution as a self-organized critical phenomenon.

K Sneppen, P Bak, H Flyvbjerg… - Proceedings of the …, 1995 - National Acad Sciences
We present a simple mathematical model of biological macroevolution. The model describes
an ecology of adapting, interacting species. The environment of any given species is …
