Testing Models of Intrinsic Brightness Variations in Type Ia Supernovae, and their Impact on Measuring Cosmological Parameters

, 2012
For spectroscopically confirmed Type Ia supernovae we evaluate models of intrinsic brightness variations with detailed data/Monte Carlo comparisons of the dispersion in the following quantities: Hubble-diagram scatter, color difference (B-V-c) between ...

Dynamical replica theoretic analysis of CDMA detection dynamics

, 2005
We investigate the detection dynamics of the Gibbs sampler for code-division multiple access (CDMA) multiuser detection. Our approach is based upon dynamical replica theory which allows an analytic approximation to the dynamics.

Poly(vinyl propionate)-grafted natural rubber as a compatibilizer in vulcanized blends of natural rubber and butadiene-crylonitrile rubber: Effects on morphology, thermal and mechanical properties

eXPRESS Polymer Letters
Natural rubber (NR) and acrylonitrile butadiene rubber (NBR) are typically incompatible due to differences in their polarity, which causes poor mechanical properties.
