Dissipative dynamics and the statistics of energy states of a Hookean model for protein folding
Tüzel, Erkan; Erzan, Ayşe (Kluwer Academic Publishers-Plenum Publishers, 2000-07)A generic model of a random polypeptide chain, with discrete torsional degrees of freedom and Hookean spring connecting pails or hydrophobic residues, reproduces the energy probability distribution of real proteins over a ... -
Evolutionary route to diploidy and sex
Tüzel, Erkan; Sevim, Volkan; Erzan, Ayşe (National Academy of Sciences, 2001-11-20)By using a bit-string model of evolution, we find a successful route to diploidy and sex in simple organisms. Allowing the sexually reproducing diploid individuals to also perform mitosis, as they do in a haploid-diploid ... -
Spectral renormalization group for the Gaussian model and ?4 theory on nonspatial networks
Tuncer, Aslı; Erzan, Ayşe (American Physical Society, 2015-08-06)We implement the spectral renormalization group on different deterministic nonspatial networks without translational invariance. We calculate the thermodynamic critical exponents for the Gaussian model on the Cayley tree ... -
The statistics of energy states of a Hookean model for proteins
Erzan, Ayşe; Tüzel, Erkan (TÜBİTAK, 2000)A generic model of a random polypeptide chain, with discrete torsional degrees of freedom and Hookean springs connecting pairs of hydrophobia residues, reproduces the energy probability distribution of real proteins over ... -
Strategies for the evolution of sex
Tüzel, Erkan; Sevim, Volkan; Erzan, Ayşe (American Physical Soc, One Physics Ellipse, 2001-12)We find that the hypothesis made by Jan, Stauffer, and Moseley [Theory Biosci. 119, 166 (2000)] for the evolution of sex, namely, a strategy devised to escape extinction due to too many deleterious mutations, is sufficient ... -
Strategies for the evolution of sex
Tüzel, Erkan; Sevim, Volkan; Erzan, Ayşe (American Institute of Physics Inc., 2001-12)The maintenance of a macroscopic sexual population is addressed. As a scenario, the mechanism of random conversion to sex, in the presence of a constant rate of mutation is examined. This scenario is very closely related ... -
Testing a hypothesis for the evolution of sex
Örçal, Bora; Tüzel, Erkan; Sevim, Volkan; Jan, Naeem; Erzan, Ayşe (World Scientific Publishing Company, 2000-07-11)An asexual set of primitive bacteria is simulated with a lit-string Penna model with a Fermi function for survival. A recent hypothesis by Jan, Stauffer, and Moseley on the evolution of sex from asexual cells as a strategy ...
