Spatial extent of precipitation events: when big is getting bigger
(Springer Science and Business Media Deutschland GmbH, 2022-03)Using a sub-selection of regional climate models at 0.11 degrees (approximate to 12 km) grid resolution from the EURO-CORDEX ensemble, we investigate how the spatial extent of areas associated with the most intensive daily ... -
Spatial slip behavior of large strike-slip fault belts: Implications for the Holocene slip rates of the eastern termination of the North Anatolian Fault, Turkey
(Blackwell Publishing Ltd, 2015-12)We present new data on Holocene slip rates for the eastern end of the North Anatolian Fault (NAF) by using the optically stimulated luminescence ages of the offset terrace deposits at two sites, where a total of four ... -
Spectral renormalization group for the Gaussian model and ?4 theory on nonspatial networks
(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
(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
(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
(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 ... -
