In situ structural and texture analyses of monoclinic phase for polycrystalline Ni-rich T49.86Ni50.14 alloy from neutron diffraction data
(Cambridge University Press, 2008-03)
Phase transformation temperatures of a polycrystalline Ni-rich Ti49.86Ni50.14 shape memory alloy were investigated using a differential scanning calorimeter. In situ structural and texture analyses of the monoclinic ...
Die-off of E. coli and enterococci in dairy cowpats
(American Society of Agricultural and Biological Engineers, 2008)
E. coli and enterococci re-growth and decay patterns in cowpats applied to pasturelands were monitored during the spring, summer fall, and winter First-order approximations were used to determine die-off rate coefficients ...
Stochastic simulation of enzyme-catalyzed reactions with disparate timescales
(CELL PRESS, 2008-10-01)
Many physiological characteristics of living cells are regulated by protein interaction networks. Because the total numbers of these protein species can be small, molecular noise can have significant effects on the dynamical ...
Millisecond switching in solid state electrochromic polymer devices fabricated from ionic self-assembled multilayers
(AIP Publishing, 2008-01-01)
The electrochromic switching times of solid state conducting polymer devices fabricated by the ionic self-assembled multilayer method has been investigated. The devices were composed of bilayers of poly(3,4-ethylenedioxy ...
H-2 model reduction for large-scale linear dynamical systems
(Siam Publications, 2008)
The optimal H-2 model reduction problem is of great importance in the area of dynamical systems and simulation. In the literature, two independent frameworks have evolved focusing either on solution of Lyapunov equations ...
Vortex washboard voltage noise in type-II superconductors
Pressure-induced phase transition in PbSc0.5Ta0.5O3 as a model Pb-based perovksite-type relaxor ferroelectric
(American Physical Society, 2008-07-04)
We report pressure-induced structural changes in PbSc0.5Ta0.5O3 studied by single-crystal x-ray diffraction and Raman scattering. The appearance of a soft mode, a change in the volume compressibility, broadening of the ...
Spatial Variability Enhances Species Fitness in Stochastic Predator-Prey Interactions
(American Physical Society, 2008-12-19)
We study the influence of spatially varying reaction rates on a spatial stochastic two-species Lotka-Volterra lattice model for predator-prey interactions using two-dimensional Monte Carlo simulations. The effects of this ...
The interaction between a monolayer of single-molecule magnets and a metal surface
(American Institute of Physics, 2008-04-01)
We calculate within density functional theory (DFT) and the LSDA+U formalism the electronic properties of a nanostructure in which single-molecule magnets Mn(12) are adsorbed via thiol groups onto the Au(111) surface. Our ...
