The prediction of the side-chain positions of proteins of known tertiary backbone structure was accomplished by a combination of neural networks and a simulated annealing method. Neural networks were used to generate distributions of side-chain dihedral angles. By eliminating network outputs with low activities, we were able to generate a reduced(More)
We consider the structures of six plant-pollinator mutualistic networks. The plants and pollinators are linked by the plant-pollinating relation. We assigned the visiting frequency of pollinators to a plant as a weight of each link. We calculated the cumulative distribution functions of the degree and strength for the networks. We observed a power-law,(More)
We report the optical properties of three dioxythiophene-based conjugated polymers: poly~3,4ethylenedioxythiophene! poly~3,4-propylenedioxythiophene!, and poly„3,4-~2,2-dimethylpropylenedioxy!thiophene.... Films of ca. 200 nm thickness of these polymers were prepared on indium-tin-oxide coated glass substrates using a potentiostatic electropolymerization(More)

The levels in Gd were identified in spontaneous fission studies. Its transition energies are remarkably similar to those in Gd. From that work, an analysis of yrast bands in even–even proton to neutron-rich Ba to Pb nuclei led to the discovery of a new phenomenon, shifted identical bands (SIB). SIBs are yrast bands in neighboring nuclei (a, b) with moments(More)
