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 ... -
Structure and expression analyses of the Fertilization Independent Seed (FIS) gene orthologs of the apomict Boechera species
(Society for Biology and Biotechnology, 2015)In this study Arabidopsis thaliana Fertilization Independent Seed 2 (FIS2) and Fertilization Independent Endosperm (FIE) genes orthologs were analysed in pseudogamous apomict and sexual Boechera species. FIS genes encode ... -
Study of drying of kappa-carrageenan gel at various temperatures using a fluorescence technique
(Taylor & Francis Inc, 2008-01)The steady-state fluorescence technique was used to study drying of kappa-carrageenan gel at various temperatures. Pyranine was doped as a fluorescence probe, and scattered light, I-sc, and fluorescence intensities, I, ... -
Study on critical behaviour in N-isopropyl acrylamide gels by using fluorescence technique
(Taylor & Francis Group, 2006-11)The steady state fluorescence (SSF) technique was used to study the sol-gel transition for the solution free radical crosslinking copolymerization of N-isopropyl acrylamide (NIPA), with N,N'-methylenebis (acrylamide) (BIS) ... -
Study on swelling of hydrogels (PAAm) at various temperatures by using fluorescence technique
(Springer US, 2007-10)Steady-state fluorescence (SSF) technique was employed for studying swelling of polyacrylamide (PAAm) hydrogels. Disc-shaped gels were prepared by free-radical crosslinking copolymerization of acrylamide (AAm) with N, N'- ... -
