Arnold Sommerfeld Center for Theoretical Physics ASC and Center for NanoScience CeNS, LMU Munich, Theresienstrasse 37, 80333 Munich, Germany
Phys Rev Lett 99:178101. 2007..To explain this effect, we generalize the Kramers-Langer theory for multidimensional barrier crossing to configuration-dependent mobility matrices...
Recombination rate and selection strength in HIV intra-patient evolutionRichard A Neher
Kavli Institute for Theoretical Physics, University of California, Santa Barbara, California, United States of America
PLoS Comput Biol 6:e1000660. 2010..With the methods developed here, more precise and more detailed studies will be possible as soon as data with higher time resolution and greater sample sizes are available...
Kinetic accessibility of buried DNA sites in nucleosomesWolfram Möbius
Arnold Sommerfeld Center for Theoretical Physics and Center for NanoScience, LMU Munchen, Theresienstrasse 37, 80333 München, Germany
Phys Rev Lett 97:208102. 2006..Close inspection reveals a surprising physical effect of flexibility-assisted barrier crossing, which we characterize within a toy model, the "semiflexible Brownian rotor."..
Dynamic mutation-selection balance as an evolutionary attractorSidhartha Goyal
Kavli Institute for Theoretical Physics, Department of Physics, University of California, Santa Barbara, CA 93106, USA
Genetics 191:1309-19. 2012..This may explain the maintenance of mitochondria and other asexual genomes...
Target search on a dynamic DNA moleculeThomas Schötz
Arnold Sommerfeld Center for Theoretical Physics and Center for Nano Science, University of Munich, Munchen, Germany
Phys Rev E Stat Nonlin Soft Matter Phys 84:051911. 2011..We also rationalize the slow exploration in the frozen limit as a subtle interplay between long jumps and long trapping times of the protein in "islands" within random DNA configurations in solution...
Correlated evolution of nearby residues in Drosophilid proteinsBenjamin Callahan
Department of Applied Physics, Stanford University, Stanford, California, United States of America
PLoS Genet 7:e1001315. 2011....
Blind source separation techniques for the decomposition of multiply labeled fluorescence imagesRichard A Neher
Kavli Institute for Theoretical Physics, University of California, Santa Barbara, California, USA
Biophys J 96:3791-800. 2009....
Competition between recombination and epistasis can cause a transition from allele to genotype selectionRichard A Neher
Kavli Institute for Theoretical Physics, University of California, Santa Barbara, CA 93106, USA
Proc Natl Acad Sci U S A 106:6866-71. 2009..These haplotype blocks disappear in a second transition to pure allele selection. Our results demonstrate that the collective effect of many weak epistatic interactions can have dramatic effects on the population structure...
Intermediate phase in DNA meltingRichard A Neher
Arnold Sommerfeld Center for Theoretical Physics and Center for NanoScience, LMU Munchen, Theresienstrasse 37, 80333 München, Germany
Phys Rev E Stat Nonlin Soft Matter Phys 73:030902. 2006..This continuous transition is in many aspects analogous to Bose-Einstein condensation. When the sequence is weakly disordered, the contour length changes discontinuously with temperature...
DNA as a programmable viscoelastic nanoelementRichard A Neher
Arnold Sommerfeld Center for Theoretical Physics and Center for NanoScience, , Munich, Germany
Biophys J 89:3846-55. 2005..Based on our findings, we suggest new dynamical roles for DNA in artificial nanoscale devices. The basepairing dynamics described here is also relevant for the extension of repetitive sequences inside genomic DNA...
