Strategies for the evolution of sex
(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 ...
Effect of annealing temperature on determining trap depths of quartz by various heating rates method
(Pergamon-Elsevier Science, 2001-12)
The aim of this study is to determine the trap parameters (trap depth E, frequency factors) of quartz using various heating rates method and also to investigate the effect of annealing temperature on determining trap depths. ...
Dissipative dynamics and the statistics of energy states of a Hookean model for protein folding
(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 ...
Signals of chaotic behavior in PMMA
(Pergamon-Elsevier Science, 2003-07)
The time evolution of the current passing through PMMA polymer thin films under 10 V at 23degreesC (296 K) was sampled at intervals ranging from 1 to 20 s. The data showed chaotic behavior in the context of pinned charge ...
Monitoring diffusion of reptating polymer chains by a direct energy transfer method: A Monte Carlo simulation
(Wiley-Blackwell, 2002-07-29)
A kinetic Monte Carlo method was used to simulate the diffusion of reptating polymer chains across an interface. A time-resolved fluorescence technique in conjunction with a direct energy transfer method was used to measure ...
Normal forms and nonlocal chaotic behavior in Sprott systems
(Pergamon-Elsevier Science, 2003-06)
The Sprott systems are used as benchmarks for investigating the applicability of the normal form transformation in estimating nonlocal properties of attractors such as positive and zero Liapunov exponents. Possibility of ...
P-T phase diagram for NH₄F
(Editions Scientifiques Medicales Elsevier, 2002-04)
In this study we obtain a P-T phase diagram of NH4F using the mean-field theory. We fit our calculated phase line equations to the experimental P-T phase diagram. By choosing appropriately the coefficients in the free-energy ...
A phase diagram near the NAC point in liquid crystals
(Elsevier Science SA, 2002-07-28)
In this study using a mean field model we obtain the phase line equations for the NA. NC and AC transitions near the NAC point in a mixture of liquid crystals. We then fit these phase line equations to the experimental ...
T-P phase diagram of ammonia solid phases I, II and III
(Elsevier Science, 2002-01-02)
In this study, using the mean field theory, we obtain temperature versus pressure phase diagram for the liquid and solid phases I, II, and III of ammonia. We fit, our phase line equations to the experimentally observed ...
A mean field model near the NAC point in liquid crystals
(Physical Soc Republic China, 2002-10)
In this study we obtain the phase line equations for the nematic-smectic A (NA), smectic A-smectic C (AC) and nematic-smectic C (NC) transitions using a mean field model. We fit these phase line equations to the experimental ...
